Buying or selling a dental practice is one of the largest financial transactions most dentists will ever be involved in. The tax consequences can be very substantial, and unlike most day-to-day financial decisions, the choices made early in any transaction largely determine the final outcome. Leave planning until after a buyer or seller has been found and most of the useful options will already be gone.
This article covers the main tax areas in dental practice transactions. For the broader process of buying or selling, including due diligence, valuations, deal structure, and finding a buyer, the service pages cover those areas in depth.

Key Takeaways
Asset sale vs share sale is the single most consequential decision, sellers usually prefer share sales, buyers prefer asset sales.
Business structure needs sorting before a sale process starts, not during it.
BADR is 18% against a standard CGT rate of 24%, but eligibility must be confirmed before heads of terms are signed.
Earn-outs are taxed as capital gains if the seller leaves, but may count as employment income (taxed higher) if they stay on.
Goodwill is usually the largest part of the sale price. Pre-April 2002 goodwill can carry different tax treatment.
SDLT applies whenever property changes hands, and is often overlooked until late in the deal.
Skipping due diligence risks inheriting tax liabilities that were never yours.
Structure first: what happens before any sale can begin
Natasha Gnanapragasam, Director of Operations, Accountancy and Tax at Samera, on what the firm does the moment a practice owner comes to them planning a sale:
“The first thing we look into is the structure. If they don’t have a proper structure before they sell the practice, we recommend they put a proper structure in place first. That step has to happen before the sale process begins, not during it. Most of the tax planning opportunities are connected to having the right structure well ahead of any transaction.”
Natasha Gnanapragasam Director of Operations
Getting the structure itself right, sole trader, partnership, or limited company, is covered in full in our guide to choosing the right business structure.
Asset sale versus share sale: the most important decision
The single most consequential tax decision in most dental practice transactions is whether the deal is structured as an asset sale or a share sale. The two structures produce completely different tax outcomes for both buyer and seller.
Asset sale
In an asset sale, specific assets transfer from seller to buyer: goodwill, the patient list, clinical equipment, the NHS contract where transferable, and the lease or freehold on the premises. For the seller where the practice is a limited company, the proceeds sit inside the company, Corporation Tax applies to any gains above book value, and the seller then faces further personal tax when extracting those proceeds. For the buyer, assets are acquired at market value, creating a fresh cost base for capital allowances and a clean slate without inheriting the company’s history.
Share sale
In a share sale, the buyer purchases the shares in the company that owns the practice. Nothing changes within the company itself. For the seller, the gain in share value since acquisition is subject to Capital Gains Tax at the individual level, and Business Asset Disposal Relief may apply at a significantly reduced rate. For the buyer, they acquire the company with its full history, including any historic tax positions, liabilities, and regulatory matters.
If you’re the one selling, the tax position needs shaping before negotiations start, not during them. We work with sellers on structuring the deal correctly from day one.
Sellers usually prefer a share sale because CGT at the individual level, potentially with BADR, is typically far lower than Corporation Tax inside the company followed by further personal tax on extraction.
Buyers often prefer an asset sale because they acquire specific assets without inheriting the company’s historic liabilities. The final structure almost always involves negotiation. Understanding each party’s tax position before that negotiation begins produces a better outcome for both sides.
If you’re the one buying, the same applies in reverse, get the structure and due diligence right before you’re locked into a deal. We support buyers through the whole process.
Capital Gains Tax and Business Asset Disposal Relief
When CGT applies
CGT arises when assets or shares that have increased in value are sold. For dental practice sellers, this typically means goodwill in an asset sale or shares in a share sale. The gain is the proceeds minus the original cost, after deducting allowable acquisition and disposal costs.
What Business Asset Disposal Relief actually saves
BADR reduces the CGT rate on qualifying business disposals. Natasha on what the financial difference between qualifying and not qualifying actually looks like:
“When BADR applies, it will be 18%. But if it hasn’t been applied, they would pay 24%, the standard CGT rate. That is a very significant difference, and it is why the structure and BADR eligibility need to be confirmed well before any sale is agreed. You cannot go back and restructure once heads of terms are signed.”
Natasha Gnanapragasam Director of Operations
The BADR rate and qualifying conditions have changed in recent years and further changes are scheduled. Always verify the current position on gov.uk before finalising any sale planning.
Confirming BADR eligibility and getting the structure right is exactly the kind of work that needs doing years ahead of a sale, not once a buyer’s at the table. Our tax planning team handles this proactively.
Earn-out arrangements have become increasingly common in dental practice sales, particularly larger ones and those involving consolidators. Part of the sale price is deferred and paid only if the practice hits agreed performance targets in the period after completion. They can bridge the gap between what a seller believes the practice is worth and what a buyer will commit to paying upfront. From a tax perspective they add meaningful complexity.
How earn-outs are taxed
Where the seller is not staying on after the sale, earn-out payments are generally treated as additional capital consideration and taxed as a capital gain, with BADR potentially applying. The complication is timing: the earn-out right must be valued at completion and taxed in the year of sale. If the actual payout is higher or lower than that valuation, a further gain or loss arises in the year the payment is received.
Where the seller remains as an employee or consultant after the sale, HMRC may treat some or all of the earn-out as employment income rather than capital. Income Tax and National Insurance rather than CGT and BADR. That is a substantially worse outcome for the seller. The structure of the post-completion arrangement and how deferred payments are documented both matter significantly. Get specialist advice before heads of terms are signed, not after.
How an earn-out is structured, and whether you stay on afterwards, materially changes the tax outcome. Our Exit Planning programme works through this as part of preparing the whole sale, not just the headline price.
Goodwill is typically the largest single component of a dental practice sale price. It represents the value beyond the tangible assets: the patient base, established reputation, NHS contract, location, and brand.
Tax treatment of goodwill
Goodwill created before April 2002 may receive different tax treatment from goodwill created after that date. For practices that have operated for a long time, this distinction can be commercially significant. Check with your accountant before assuming a standard CGT treatment applies to the entire goodwill value.
How dental practices are valued
Dental practices are typically valued using a multiple of normalised EBITDA or as a proportion of annual turnover. NHS, private, and mixed practices attract different multiples and the state of the market at the time of sale also matters. A supportable and realistic goodwill valuation matters not just for the transaction itself but because HMRC can challenge figures that look unrealistic for the sector.
A supportable, evidence-based goodwill figure protects you in negotiation and against HMRC challenge alike. Our valuations service gives you that starting point.
SDLT applies when buying freehold or leasehold commercial premises. For non-residential property it is charged in bands: 0% on the first £150,000, 2% on the portion between £150,001 and £250,000, and 5% on anything above that. Check the current bands on gov.uk before completing any property transaction as these can change.
SDLT also arises when moving property between personal ownership and a company, when a long lease is granted or assigned, and when a practice purchase involves the grant of a new lease on surgery premises. Model the cost early in the process. It is sometimes overlooked entirely until the deal is almost done.
Due diligence and preventing inherited tax problems
Natasha on why proper due diligence before completing any acquisition matters:
“Buyers can inherit tax liabilities from a previous owner if they are not careful. That is exactly the reason we ask them to do a proper due diligence. So in such cases, they are not inheriting any tax liabilities they didn’t know about. Due diligence is not optional, it is what separates a clean acquisition from one that comes with problems baked in.”
Inherited tax liabilities are exactly what proper due diligence catches before completion, not after. Our financial due diligence service is built specifically to find these before they become your problem.
An NHS dental contract is not a freely transferable commercial asset. It requires NHS England approval for any change in the entity holding it. When a practice changes hands, the NHS contract arrangements need careful management to preserve both the contract and the provider’s NHS pension position. Getting this wrong can result in loss of contract income or pension complications that take years to resolve.
Getting the tax right takes time you don’t have once a deal is moving
Every decision in this article gets harder to change once a buyer or seller is at the table. Structure needs sorting first. BADR eligibility needs confirming years before completion, not during it. Due diligence needs doing properly before contracts are signed, not after problems surface.
None of this is complicated on its own. What makes it costly is leaving it until a transaction is already underway, at which point most of the good options are already gone. Start the tax conversation as early as the commercial one, and the outcome looks very different from starting it once heads of terms are on the table.
Buying or selling a practice touches every part of your accounts, structure, valuation, tax planning, due diligence. Find out how we support both sides of the transaction.
Is a share sale or an asset sale better when selling a dental practice?
From the seller’s perspective, a share sale is usually more tax-efficient. CGT at the individual level, potentially with BADR, is typically far lower than Corporation Tax inside the company followed by further personal tax on extraction. From the buyer’s perspective, an asset sale is often preferred because they avoid inheriting the company’s historic liabilities. The final structure usually involves negotiation between both parties.
What is the actual tax saving from Business Asset Disposal Relief?
Where BADR applies, the rate is 18%. Where it doesn’t, sellers pay the standard Capital Gains Tax rate of 24%. That six-point difference is significant on a practice sale, and eligibility needs confirming well before any sale is agreed, since structure can’t be changed once heads of terms are signed.
Why does business structure need sorting before starting a sale process?
Most of the tax planning opportunities in a sale are tied to having the right structure in place well ahead of any transaction. Once a sale process has started, there’s little room left to restructure without disrupting the deal itself. Getting structure right is the first thing to address, before finding a buyer, not during negotiations.
What is goodwill in a dental practice and how is it taxed?
Goodwill is the value beyond tangible assets: the patient base, reputation, NHS contract, location, and brand. In an asset sale, the company pays Corporation Tax on any gain above book value. In a share sale, the seller pays Capital Gains Tax on the gain in share value. Goodwill created before April 2002 may receive different treatment, confirm with your accountant if your practice predates that.
What is an earn-out and how is it taxed?
An earn-out is a deferred element of the sale price paid only if the practice hits agreed post-completion performance targets. Where the seller is not staying on, earn-out payments are generally taxed as capital gains. Where the seller remains as an employee or consultant, HMRC may treat the earn-out as employment income taxed at higher rates. The post-completion arrangement structure determines which applies.
Does SDLT apply when buying a dental practice?
SDLT applies when property changes hands as part of the transaction. If the deal involves only goodwill and equipment with no property element, SDLT does not typically arise. Where surgery premises are included, SDLT can be a significant additional cost and should be calculated early in the planning process.
What happens if a buyer doesn’t do proper due diligence?
Buyers can inherit tax liabilities from the previous owner if due diligence isn’t done properly. This is exactly why due diligence isn’t optional, it’s what separates a clean acquisition from one that comes with problems already baked in, discovered only after completion.
Does an NHS contract automatically transfer when a dental practice is sold?
No. An NHS dental contract is not a freely transferable commercial asset. It requires NHS England approval for any change in the entity holding it, handled through the formal contract variation process. Getting this wrong can affect both the contract itself and the outgoing provider’s NHS pension position.
How far ahead should I plan the tax side of a practice sale?
At least two to three years before completion. Confirming BADR eligibility, reviewing the company structure, planning pre-sale profit extraction, and choosing the most appropriate sale structure all require time. Planning that begins only after a buyer appears is almost always less tax-efficient.

Most of the expensive accounting and tax mistakes made by dentists are not the result of cutting corners or taking deliberate risks. They come from not knowing what the rules require, using advice that is too generic to account for how dental practice finances actually work, or simply being too focused on clinical work to pay sufficient attention to the business side.
What this article covers
The eleven accounting and tax mistakes that come up most frequently in UK dental practices.
What causes each mistake, what it actually costs, and what fixes it.
Real observations from Samera’s specialist dental accountants on what they find most often.
Key Takeaways
Structure underpins almost everything else, tax, business and bookkeeping structure all compound if wrong from the start.
Poor record-keeping is the root cause of most other problems here, and the easiest one to fix.
Missing an HMRC deadline triggers an automatic penalty. Being late is enough, no error required.
Payments on account catch most self-employed dentists off guard the first time. Setting aside money monthly from day one avoids it.
Mixing personal and business finances is the most avoidable compliance problem. One account, one card, fixes it.
Not separating NHS and private income breaks VAT treatment and NHS pension reporting at once.
Getting associate employment status wrong now carries real backdated PAYE and NI risk since HMRC withdrew the self-employment concession in 2023.
The one mistake that underlies almost everything else
Natasha Gnanapragasam, Director of Operations, Accountancy and Tax at Samera, when asked to name the single most common mistake she sees across dental practice accounts:
“Structure. That is everything, it is the most significant thing I could think of. It can be your tax structure, your business structure, or even how you structure your accounting books and bookkeeping. Everything matters. If you don’t have a proper structure in place before you take on anything, it ends up costing you more in fees, more in taxes, more in time. Structure underpins everything else.”
Natasha Gnanapragasam Director of Operations
1. Poor record-keeping
The root cause of most other accounting problems. Receipts get lost. Transactions end up in the wrong category or are forgotten entirely. Cash purchases of clinical consumables disappear from the records entirely. By year-end, the accountant is reconstructing rather than reviewing.
The consequences are significant. Expense claims cannot be supported if HMRC opens an enquiry. Your accountant spends more time and charges more. Tax returns contain avoidable errors. And nobody in the practice has had a reliable view of how it is actually performing for months.
The fix is not complicated: keep digital records of everything, reconcile your bank account monthly, and review the financial picture regularly. Cloud accounting software has made this substantially less time-consuming than it used to be.
Reconciling accounts monthly and keeping digital records from day one is exactly what our ongoing accountancy service handles, so this stops being something you have to manage yourself.
Missed HMRC deadlines trigger automatic penalties. You do not need to have made an error. Simply being late is enough. The most commonly missed in dental practices:
Self Assessment: 31 January. An automatic £100 penalty applies from the moment the deadline passes.
Corporation Tax: nine months and one day after the accounting year-end.
VAT returns: one month and seven days after each quarterly period.
RTI submissions: on or before every single payday. Not monthly. Every pay date.
P60s: 31 May. P11Ds: 6 July.
A rolling deadline calendar combined with accounting and payroll software that handles electronic submissions automatically solves most of this. For a full compliance guide, see our article on compliance and Making Tax Digital.
This is the most common financial shock in dental self-employment and it is almost always caused by nobody explaining it in advance. Payments on account are advance payments towards the following year’s tax bill: half due in January alongside the current year’s bill, half in July. In a high-earning year you could effectively be paying two years’ worth of tax simultaneously in January.
The fix is simple and completely reliable: set aside a percentage of income monthly into a dedicated tax savings account from the very first month of self-employment. Your accountant can suggest a realistic percentage.
Charles Suthakran, Business Development Executive, Accountancy and Tax at Samera, on why this is consistently the most avoidable compliance problem he sees:
“One business account, one business card, used for nothing else. It sounds almost too basic to be worth saying, but it’s the single thing that causes the most trouble. What happens is that one account ends up doing two jobs, the practice’s and the owner’s. It reconciles fine day to day, so nobody worries. The problem only shows up when HMRC asks a question, because you have to prove a cost was a business cost, and you can’t do that cleanly if it’s tangled up with personal spending. A legitimate claim you’re fully entitled to gets disallowed simply because you can’t evidence it.”
Charles Suthakran Dental Accountant
5. Under-claiming allowable expenses
Many dentists pay more tax than they need to because they assume certain expenses do not qualify without ever checking. Natasha on what is most consistently missed:
“The most common things missed are use of home, associates don’t understand how to claim it, so we educate them, and travel between practices. But beyond those, they also don’t understand the entertainment allowance for each employee per year, or that they can claim for loupes and clinical equipment they’ve bought. These are small things but they all add up. Proper guidance makes all the difference.”
Use of home, travel between practices, the entertainment allowance, clinical equipment like loupes, these are the exact areas our associate accounts service is built to catch.
6. Not separating NHS and private income in the accounts
This one is specific to dentistry and it comes up in almost every set of mixed practice accounts Samera reviews. NHS and private income get recorded together, usually because the bookkeeping software has not been set up to separate them, and the downstream consequences are significant.
The first problem is VAT. Most NHS clinical income is exempt. Some private cosmetic work is taxable. Product sales are taxable. If income streams are bundled together, the correct VAT treatment cannot be calculated and partial exemption cannot be applied accurately.
The second problem is NHS pension calculations. Associates and practices both have reporting obligations to the NHSBSA based on NHS pensionable earnings. If NHS income is not tracked separately, those calculations are unreliable. Errors in NHS pension reporting typically surface only when someone is approaching retirement.
The third problem is management information. If you cannot see how much of your income is NHS and how much is private, you cannot make informed decisions about treatment mix, pricing, or whether an associate arrangement is actually profitable.
Natasha on why this genuinely requires specialist knowledge:
“Dentists need to know how to recognise the income, NHS and private, and how to record it. Because beyond every set of numbers, there are special nuances that apply. Those nuances can only really be determined by a specialist accountant. Not by a general accountant. That’s one of the most important distinctions between what a specialist does and what a generalist does in this space.”
Getting the NHS and private split right from the start protects your VAT position, your NHS pension reporting, and your ability to actually see how the practice is performing.
7. Getting the VAT position wrong on cosmetic work and retail
Most clinical treatment is VAT-exempt but purely cosmetic procedures and product sales are generally taxable. Getting this wrong creates under-declarations that HMRC can pursue going back several years. For practices with mixed income, partial exemption rules limit how much input VAT can be reclaimed. Specialist VAT review is worth the cost for any practice generating meaningful income from cosmetic or retail work.
Treating associates as self-employed when their practical working arrangement looks like employment can result in the practice owing back PAYE and National Insurance on all payments made, plus interest and penalties, potentially going back several years. This risk increased significantly when HMRC withdrew the specific concession treating dental associates as self-employed by default in April 2023.
The test is not what the contract says. It is what the working arrangement actually looks like in practice. Use HMRC’s CEST tool for each associate independently and keep the results on file.
9. Staying in the wrong business structure too long
Most dentists start in a structure that makes sense at the time. The mistake is not reviewing it as income grows and responsibilities change. An associate earning modestly as a sole trader is in the right structure. That same person ten years later as an established practice owner with significant profits probably is not. Review your structure every two to three years.
Tax planning is only useful when done in advance. The strategies that produce the best outcomes, pension contributions, capital allowances timing, BADR qualification for a future sale, all require lead time. Dentists who plan throughout the year pay less tax than those who start planning when the bill arrives.
11. Using a generalist accountant for a specialist area
Natasha on what she finds when a practice switches from a generalist accountant to Samera, and what gets corrected first:
“When a new dental client boards with us, most of them don’t have the correct approach to bookkeeping. Either they’re on cash basis when accruals would be more accurate, or there are incorrect categorisations throughout. And the NHS income nuances, how to allocate it, how to split it from private, how it feeds into pension calculations, that’s almost always been handled incorrectly. That’s the first thing we correct. And it matters because every number beyond it is built on that foundation.”
Natasha Gnanapragasam Director of Operations
A generalist accountant will commonly miss NHS income structures, employment status risks for associates, partial VAT exemption in mixed practices, capital allowances on clinical equipment, NHS pension complexity for both employed staff and associates, and BADR qualifying conditions for practice sales. The cost of specialist advice is almost always less than the cost of the errors it prevents.
Natasha on the financial consequences she sees most often:
“The most expensive outcome I have seen is not the tax itself, it is the penalties and interest that follow when something has gone wrong and was not rectified quickly. HMRC charges very heavy interest. The penalties are significant. If something has gone wrong and there’s a payment delay, the client ends up paying penalty and interest charges on top of the tax they already owe. That combination is the most costly thing. And it is almost always avoidable with proper systems and proper advice from the start.”
Penalties and interest are the costliest part of any HMRC issue, not the original tax. Tax Investigation Insurance Cover means Samera handles the enquiry on your behalf without the bill landing on you directly.
The dentists who avoid them are not particularly financially sophisticated. They just do the straightforward things: keep tidy records, separate NHS and private income from the start, use good software, review their structure periodically, and work with people who actually understand dental practice. None of it is complicated. It just requires doing it consistently.
Dental Accounts Mistakes: FAQs
What is the single most common mistake dental practices make with their accounts?
Structure. That covers tax structure, business structure, and how the bookkeeping itself is set up. Getting any of these wrong from the start tends to compound, costing more in fees, tax, and time the longer it goes uncorrected.
What happens if personal and business finances are mixed together?
It reconciles fine day to day, so the problem often goes unnoticed until HMRC asks a question. At that point, a cost has to be proven as a business cost, and that can’t be done cleanly if it’s tangled up with personal spending. Legitimate claims can get disallowed simply because they can’t be evidenced.
What is the penalty for a late Self Assessment return?
An automatic £100 penalty applies from the moment the 31 January deadline passes, regardless of whether any tax is owed. Further daily penalties of £10 apply from three months late, plus larger fixed penalties at six and twelve months. Interest is charged on any unpaid tax from the due date.
Why does it matter whether NHS and private income are recorded separately?
Three reasons. First, VAT: the correct treatment and partial exemption calculations cannot be applied accurately if income streams are bundled. Second, NHS pension: reporting to the NHSBSA is based on NHS pensionable earnings, which cannot be accurately calculated without separate tracking. Third, management information: you cannot make good decisions about treatment mix or pricing if you cannot see the split between NHS and private.
How far back can HMRC investigate a dental practice?
For innocent errors, typically up to four years. For careless errors, up to six years. For deliberate errors or fraud, up to twenty years. Employment status errors where associates were incorrectly treated as self-employed can result in PAYE and NI assessments going back several years with interest applied throughout.
Can employment status errors be corrected after the fact?
It is possible, but expensive. HMRC will typically require payment of all unpaid PAYE and National Insurance plus interest for every affected year, and may also impose penalties. Correcting the position voluntarily before HMRC identifies it through a compliance check is considerably less costly than being discovered.
Is a specialist dental accountant worth the additional cost?
For the vast majority of dentists, particularly practice owners, anyone in a group structure, and anyone planning a future sale, yes. The cost of specialist advice is typically recovered many times over through better expense claims, correct tax planning, avoided penalties, and better-structured business arrangements over time. The NHS and private income nuances alone can only be handled correctly by a specialist.

Most dentists spend the majority of their careers building a practice and considerably less time planning what happens at the end. The financial decisions made in the final five to ten years before retirement or exit have a bigger impact on the eventual outcome than almost anything done earlier. Starting to think about this earlier than feels immediately necessary is almost always worth it.
This article covers retirement, succession and Inheritance Tax specifically. For the full picture across tax, payroll and compliance read our full guide: Dental Accounting and Tax, A Complete Guide
What this article covers
How the NHS Pension Scheme works for dentists and why the section you belong to matters.
The lifetime allowance abolition in April 2024 and what dentists need to update in their planning.
Private pensions alongside NHS pension: why most dentists benefit from both.
Succession options: sale, family transfer, and management buyout.
Inheritance Tax and Business Property Relief: what it covers and what can lose it.
Key Takeaways
The pension lifetime allowance was abolished in April 2024. If contributions were limited because of it, that’s worth revisiting.
The NHS Pension Scheme has three sections (1995, 2008, 2015) with different pension ages and accrual rates.
Higher earners can trigger an unexpected tax charge through the annual allowance, even without a private contribution.
There are four main succession routes: external sale, sale to associates, family transfer, and phased retirement.
Practices prepared two to three years ahead of a sale achieve better outcomes than those sold reactively.
Business Property Relief can reduce Inheritance Tax on qualifying practice shares, but the rules are changing and eligibility needs regular review.
Gifts to individuals fall outside your estate for Inheritance Tax after seven years, tapering from year three.
An important boundary: what accountants do and do not advise on
Natasha Gnanapragasam, Director of Operations, Accountancy and Tax at Samera, on where accounting advice ends and regulated financial advice begins:
“Pension is something we don’t advise on directly, we’re not regulated to advise on pension schemes. What we can tell clients is what allowance they can utilise within the year, what the HMRC allowance is, and what tax charges might apply if they go over it. Beyond that, it is not within our scope. For actual pension scheme advice, which scheme, what level to contribute, how to structure retirement income, clients need a regulated financial adviser who specialises in this area.”
Natasha Gnanapragasam Director of Operations
With that boundary clear, this article covers the tax and planning aspects of retirement, succession, and Inheritance Tax that fall within the accounting picture.
The NHS Pension Scheme
For dentists who have carried out NHS work, the NHS Pension Scheme is one of the most financially valuable assets they will accumulate over a career. It is a defined benefit scheme: income in retirement is based on years of service and pensionable earnings rather than on the performance of an investment fund. That predictability and protection is something private pensions cannot replicate.
The three sections
1995 section. Final salary scheme with a normal pension age of 60. The most generous in terms of accrual rate. Closed to new entrants but still active for existing members.
2008 section. Career average scheme with a normal pension age of 65. Less generous accrual than the 1995 section.
2015 section. Career average scheme with a normal pension age tied to state pension age. Applies to most dentists who joined after April 2015, and to some existing members following the 2022 McCloud remedy.
Many longer-serving NHS dentists have benefits accrued across more than one section. Understanding which section your benefits sit in, and how they have built up across sections, is the starting point for any meaningful retirement planning.
For higher-earning dentists, the pension annual allowance creates a specific planning challenge. The NHS pension is a defined benefit scheme, so each year’s accrual is measured as a notional increase in pot value rather than as a cash contribution. For some senior dentists that notional accrual can exceed the annual allowance and create an unexpected tax charge. This requires careful planning around private contributions, scheme pays elections, and sometimes deliberate management of NHS pensionable income. Specialist advice is important here rather than optional.
Getting caught by the annual allowance unexpectedly is common and avoidable with the right planning around contributions and scheme pays elections. Tax Planning for Dentists looks at this alongside your wider tax position.
The lifetime allowance abolition: what changed in April 2024
The pension lifetime allowance was abolished from April 2024. For many dentists this is genuinely significant news that has not been well communicated. A meaningful number of practitioners are still operating pension strategies that were designed specifically to avoid a limit that no longer exists.
What the lifetime allowance was
The lifetime allowance set a cap on the total value of pension savings a person could accumulate across all schemes before additional tax charges applied. It was a real constraint for senior dentists with long NHS careers and meaningful private pension savings alongside them. Many were advised specifically to stop contributing to private pensions to avoid breaching the cap.
What changed
The lifetime allowance was removed entirely from April 2024. There is no longer any limit on total lifetime pension savings. The annual allowance, which limits how much you can contribute in a single year and still receive full tax relief, remains in place. But the lifetime ceiling is gone.
What dentists need to do now
If you or your financial adviser made decisions to limit pension contributions specifically because of lifetime allowance concerns, those decisions should be revisited. Some dentists stopped private pension contributions years ago to stay below the cap. With the cap gone, the tax efficiency of pension contributions is restored for those who were previously constrained. The interaction with the annual allowance still needs careful management, particularly for NHS pension members where defined benefit accrual can itself consume a significant portion of the limit. But the reason for holding back on pension saving because of the lifetime allowance no longer exists.
If you were advised to limit pension contributions because of the lifetime allowance, review that advice now
The lifetime allowance was abolished in April 2024. Strategies built around avoiding it may no longer serve your best financial interests. A regulated financial adviser who understands the NHS pension and the current rules can model what is now possible.
In our experience, most dentists benefit from holding some private pension savings alongside their NHS pension rather than relying on the NHS scheme alone. Private pensions provide additional retirement income, more flexibility in when and how income is drawn, and a vehicle for tax-efficient contributions in high-earning years. The right balance depends on your career stage, income level, and how close retirement actually is.
The practice as a retirement asset
For practice owners, the practice itself is typically the largest single asset and the intended primary source of retirement funding. This makes the eventual sale or transfer, and the tax efficiency of that process, central to retirement planning rather than separate from it. Dentists who treat the practice sale and pension planning as two completely separate conversations often find the combined outcome is less efficient than it could have been with integrated planning from the start.
Sale to existing associates or a management team. Preserves practice culture and continuity. May require vendor financing or phased payments if the team cannot fund the full purchase price immediately.
Transfer to family. Has Inheritance Tax implications and may trigger Capital Gains Tax. Holdover relief and Business Property Relief can both be relevant but need to be planned carefully rather than assumed.
Phased retirement. Reducing clinical hours progressively while retaining ownership, bringing in an associate or partner to manage operations, and selling later. Requires clear legal documentation and a defined exit point to avoid disputes.
Whichever succession route fits, an accurate valuation is the starting point for the decision. Our Practice Valuations service gives you a clear, evidence-based figure to plan around.
These are the exact areas our Exit Planning programme is built around, preparing a practice over 12 to 18 months so it reaches a buyer already in the best possible shape.
For practice owners, Inheritance Tax planning is one of the most important and most commonly overlooked aspects of long-term financial planning. A practice built up over decades can represent a very significant estate asset, and without planning a substantial portion of its value could pass to HMRC rather than to the people it was intended for.
Business Property Relief
Business Property Relief can substantially reduce Inheritance Tax on qualifying business assets. For most dental practice owners this means shares in a qualifying trading company can pass on death or as a lifetime gift with significant Inheritance Tax relief, provided the conditions are met. The rules around how much relief applies have changed recently, so the exact position needs confirming with your accountant rather than being assumed:
The asset must be relevant business property, specifically shares in an unlisted trading company.
The company must be predominantly trading rather than holding investments.
The shares must have been held for at least two years before the transfer.
BPR can be lost or reduced if the company holds significant non-trading assets. Investment property, substantial cash reserves beyond operational needs, and non-trading subsidiaries are the most common ways this happens. Large retained profits sitting as cash in the company is one of the most frequent inadvertent causes. Review qualifying status regularly, particularly as the practice changes.
Gifts to individuals are potentially exempt from Inheritance Tax if the donor survives seven years from the date of the gift. Gifts made within the final seven years remain subject to IHT, but on a tapering basis from year three onwards. Holdover relief may allow Capital Gains Tax to be deferred on gifts of company shares, meaning the gain is passed to the recipient rather than triggered immediately.
Wills and estate planning
A properly drafted will is the foundation of any IHT plan for a practice owner. It needs to address who inherits practice shares, whether BPR will be available on those assets as structured, how the practice continues to operate if the owner dies unexpectedly, and whether life assurance is in place to cover any IHT liability that cannot otherwise be mitigated.
Planning ahead is what actually changes the outcome
The pattern running through all of this is the same one: pension strategy, succession, and Inheritance Tax all reward decisions made years before they’re needed, not the year they become urgent. A practice prepared two to three years ahead of sale performs differently to one sold reactively. A will that accounts for Business Property Relief protects value that an outdated one doesn’t. Pension contributions that were paused for the wrong reason can simply be restarted, but only once someone notices they were paused for a reason that no longer applies.
None of this replaces regulated financial advice on pensions, or legal advice on wills and estate structuring. What it does is give you the tax and planning picture accountants are positioned to see, so those conversations with the right specialist start from an informed position rather than a blank one.
The five to ten years before retirement or exit carry more weight than people expect. Starting earlier than feels necessary is, consistently, the better call.
The pension lifetime allowance was abolished from April 2024. There is no longer any cap on total lifetime pension savings. The annual allowance, which limits how much can be contributed in a single year while still receiving full tax relief, remains. Dentists who previously limited pension contributions specifically to avoid the lifetime allowance should review their strategy now.
What are the three sections of the NHS Pension Scheme?
The 1995 section is a final salary scheme with normal pension age of 60. The 2008 section is a career average scheme with normal pension age of 65. The 2015 section is a career average scheme with pension age tied to state pension age. Many longer-serving NHS dentists have benefits accrued across more than one section.
How does the pension annual allowance affect NHS dentists?
The NHS pension is a defined benefit scheme, so each year’s accrual is measured as a notional increase in value rather than as a cash contribution. For higher-earning dentists, that notional accrual can exceed the annual allowance on its own and create an unexpected tax charge, even without making any private pension contribution. This needs careful planning around scheme pays elections and, sometimes, managing NHS pensionable income deliberately.
Can Samera advise on which pension scheme to join?
No. Pension scheme advice is regulated financial advice that requires a regulated financial adviser. Samera can advise on the tax implications of pension contributions, what the annual allowance is, and what tax charges apply if it is exceeded. For decisions about which scheme to join or how to structure retirement income, you need a specialist financial adviser.
What steps prepare a dental practice for a good sale outcome?
Practices that achieve the best outcomes are typically prepared two to three years in advance. Key steps include clean, consistent accounts that clearly show EBITDA, confirming BADR eligibility and maintaining qualifying conditions, keeping NHS contract arrangements in good standing and transferable, resolving outstanding compliance issues before a buyer sees them, and documenting key staff contracts and notice periods properly.
Does Business Property Relief apply to dental practices?
Most actively trading dental companies qualify for Business Property Relief on shares held for at least two years, provided the company is predominantly trading. The amount of relief available has changed recently, so this needs checking against current rules rather than assumed. BPR can also be lost if significant non-trading assets are held, including large cash reserves. Qualifying status should be reviewed regularly as the practice changes.
What is the seven-year rule for Inheritance Tax?
Gifts to individuals are potentially exempt from Inheritance Tax if the donor survives seven years from the date of the gift. Gifts made within the final seven years may still attract IHT, tapering from year three onwards. This is relevant for dentists planning to transfer practice shares or other significant assets to family members during their lifetime.

Dental practice compliance has grown considerably more demanding over the past decade. HMRC deadlines, digital record-keeping requirements, quarterly reporting under Making Tax Digital, and the expanding list of software-based submission obligations all need managing alongside the clinical work. Unlike a missed appointment, a missed HMRC deadline triggers an automatic penalty with no warning and no grace period.
The HMRC deadlines dental practices must hit and what happens when they do not.
Record-keeping: what HMRC actually expects and for how long.
Making Tax Digital for VAT (already compulsory) and for Income Tax (live from April 2026).
The three things dental associates consistently get wrong about MTD.
Accounting software and which options dental practices in the UK actually use.
Key Takeaways
A missed HMRC deadline triggers an automatic penalty, whether or not tax is owed, with no warning and no grace period.
Self Assessment, Corporation Tax, VAT and payroll all run on different deadlines. Missing any one is treated as a compliance failure.
Good record-keeping is what lets you defend what you’ve filed if HMRC opens an enquiry. Clean records mean a short enquiry. Gaps get read against you.
The single habit that prevents most disputes: one business account, one business card, used for nothing else. MTD for VAT has applied since 2022.
MTD for Income Tax is now live in stages. Quarterly updates don’t mean paying tax more often, payment dates haven’t changed.
Xero, QuickBooks, Sage and Hubdoc are the platforms used in UK dentistry, and all are MTD-compatible.
The compliance failure that one habit prevents
Charles Suthakran, Business Development Executive, Accountancy and Tax at Samera, on the single most common compliance failure he sees across dental practices, and the one thing that eliminates it:
“One business account, one business card, used for nothing else. It sounds almost too basic to be worth saying, but it’s the single thing that causes the most trouble, and it’s entirely avoidable. What happens in practice is that one account ends up doing two jobs, the practice’s and the owner’s. A card gets used for stock and for the weekly shop.
Money moves between personal and business without anyone noting why. It reconciles fine day to day, so nobody worries about it. The problem only shows up when HMRC asks a question, because at that point you have to prove a cost was a business cost, and you can’t cleanly do that if it’s tangled up with personal spending. A legitimate claim you’re fully entitled to gets disallowed simply because you can’t evidence it. Keep the two completely separate from day one, and most of that risk just disappears.”
Charles Suthakran Dental Accountant
HMRC deadlines dental practices must meet
Self Assessment for associates and sole traders
31st January: online Self Assessment return deadline, plus any tax owed for the previous year.
31st July: second payment on account.
5th October: deadline to register for Self Assessment if newly self-employed.
Missing the 31 January deadline triggers an automatic £100 penalty from the moment it passes, regardless of whether you owe any tax at all. Further charges apply at three months, six months, and twelve months late. Interest runs on any unpaid tax from the due date.
Payments on account are advance payments towards next year’s tax bill, 50% due in January alongside the current year’s bill, and 50% in July. In a high-earning year you could effectively be paying two years’ worth simultaneously. Set aside a monthly percentage from the start of self-employment. Full details are in our article on taxes for dental associates.
Corporation Tax for limited companies
Payment: nine months and one day after the accounting year-end.
CT600 return: twelve months after the accounting year-end.
Filing the CT600 late triggers an automatic fixed penalty even if no tax is owed, rising in stages the longer it’s left, with a further surcharge added on any unpaid tax once you’re six and twelve months late. Repeated late filing increases the fixed penalties further. Paying the tax late is a separate matter and triggers daily interest from the day after the due date, regardless of whether the return itself was filed on time.
VAT-registered practices submit quarterly returns due one month and seven days after the end of each VAT period. Manual submissions through HMRC’s old online portal are no longer accepted. Everything must go through MTD-compatible software.
A late submission adds a penalty point rather than an immediate fine, and once you reach the threshold for your filing frequency, a fixed penalty applies, repeating for every late submission after that until compliance is restored. Late payment is penalised separately and depends on how many days late the payment is, alongside interest that runs from day one until the VAT is paid in full.
RTI submissions: on or before every single payday. Not monthly. On or before each pay date.
P60s: issued to all employees by 31st May.
P11Ds: submitted to HMRC by 6th July.
Class 1A NI: due 19th July, or 22nd July for electronic payment.
Missing an RTI deadline triggers a monthly late filing penalty, scaled to the number of employees in the PAYE scheme. The first missed submission in a tax year usually goes unpenalised, but persistent late filing brings a further charge on the tax and National Insurance that should have been reported.
Getting payroll deadlines wrong compounds fast, RTI penalties apply monthly and per scheme. Our Payroll and Pensions service handles submissions, auto-enrolment and NHS pension reporting so deadlines aren’t something you have to track yourself.
HMRC can open an enquiry into any return at any time. If supporting records cannot be produced, expense claims can be disallowed and estimated assessments raised. Good record-keeping is not administrative tidiness for its own sake, it is what lets you defend what you have filed.
NHS income records: remittance statements, schedule of fees, UDA reports.
Private income records: fee schedules, receipts, patient billing.
Charles on what triggers most enquiries and how the outcome differs completely based on whether records exist:
“The enquiries I see rarely start with anything dramatic. It’s usually a figure that looks out of step, margins that don’t sit right for the size of the practice, a sharp swing in costs year on year, or private income that looks light against the number of surgeries running. That’s often enough for HMRC to open a check and start asking for the records behind the numbers.
What they’re really testing is whether what’s on the return can be backed up. And that’s where the two types of practice split completely. The one with clean, current records hands over the bank statements, the invoices, the payroll, all tied together, and the enquiry tends to be short and uneventful, because there’s nothing to find and everything to show.
The one without spends weeks reconstructing a year they should have recorded as it happened, and every gap gets read in HMRC’s favour, not theirs. Same underlying business, often the same actual tax position, but a totally different experience, and a totally different bill once disallowed costs and penalties are added. The records don’t change what’s true. They change whether you can prove it.”
An enquiry is expensive whether or not you’ve done anything wrong, the cost is in the time and the professional fees defending it. Tax Investigation Insurance Cover means Samera handles the enquiry on your behalf without the bill landing on you directly.
All VAT-registered businesses have been required to follow MTD rules for VAT since April 2022. For dental practices that are VAT-registered because they provide cosmetic or other taxable services, VAT records must be kept digitally and returns must be submitted through MTD-compatible software. The old HMRC online portal no longer accepts submissions.
MTD for Income Tax Self Assessment: live from April 2026
This is the change that affects most dental associates, and it is rolling out in stages by income threshold over the next two years. Charles on the three misunderstandings he sees most consistently when he talks to associates about it:
“The reaction is usually one of two things: either they’ve never heard of it, or they assume it’s been pushed back again and isn’t really happening. It’s been delayed so many times that there’s a fair bit of ‘I’ll believe it when I see it.’ But for associates earning over £50,000, it’s live now, and that’s most of them. The misunderstandings are consistent.
The biggest one is that they think quarterly updates mean paying tax four times a year, they don’t. The payment dates haven’t changed at all. The updates are just summaries of income and expenses sent throughout the year. The second is that they assume they can carry on handing everything over in a carrier bag in January. That stops working, because the records now have to be kept digitally in compatible software as you go.
And the third is the threshold itself: it’s on gross income, your total billings, not your take-home profit. An associate billing £90,000 who thinks of their income as the £55,000 that lands in their account assumes they might be under the threshold. They’re not. There is a soft landing in the first year where HMRC won’t issue penalty points for late quarterly updates, but I’d treat that as breathing room to get the system right, not a reason to ignore it.”

In short: Xero is the most widely used platform in UK dentistry and the one Samera uses for dental finance automation. QuickBooks is popular with associates and smaller practices. Sage is more common in larger practices and groups with complex payroll requirements. Hubdoc works alongside Xero for document management. All four are MTD-compatible.
Practical steps for staying compliant
Move to cloud accounting software. Paper records and spreadsheets are not sufficient for MTD compliance.
Review your financial position monthly rather than only at year-end.
Keep business and personal finances completely separate from day one.
Plan for tax monthly. Setting aside income every month makes January and July payment dates far less stressful.
Work with an accountant who understands dental practice specifically, not just general small business accounting.
Getting the day-to-day compliance right is one thing, planning around it so you’re not just reacting to deadlines is another. Our tax planning for dentists services look at your position proactively rather than compliance in isolation.
Most of what causes trouble in this article traces back to the same root cause: things get sorted after the fact instead of as they happen. A missed deadline is rarely about the date itself, it’s about records or payments not being ready when the date arrived. An HMRC enquiry rarely starts with anything dramatic, it starts with a figure that doesn’t add up because the paper trail behind it was never kept properly.
The single change that prevents the most common problem, keeping one business account and card completely separate from personal spending, costs nothing and takes no expertise. The same is true of moving to digital records before MTD forces the issue, rather than after.
None of this requires getting every deadline memorised. It requires a system, cloud software, monthly reviews, and an accountant who knows dental practices specifically, that keeps you ahead of what HMRC expects rather than reacting to it.
What happens if a dental practice misses a Corporation Tax deadline?
Filing the CT600 late triggers an automatic fixed penalty even if no tax is owed, rising in stages the longer it’s left, with a further surcharge added on any unpaid tax once you’re six and twelve months late. Repeated late filing increases the fixed penalties further. Paying the tax late is a separate matter and triggers daily interest from the day after the due date, regardless of whether the return itself was filed on time.
What happens if a VAT return is submitted late?
A late submission adds a penalty point rather than an immediate fine. Once you reach the threshold for your filing frequency, a fixed penalty applies, repeating for every late submission after that until compliance is restored. Late payment is penalised separately and depends on how many days late the payment is, alongside interest that runs from day one until the VAT is paid in full.
How long do dental practices need to keep financial records?
Self-employed individuals need to keep records for at least five years after the 31 January filing deadline for the relevant tax year. Limited companies need six years from the end of the relevant accounting period, and VAT records also need to be kept for at least six years.
What happens if I can’t produce records during an HMRC enquiry?
Expense claims can be disallowed and estimated assessments raised if supporting records don’t exist. Practices with clean, current records tend to have short, uneventful enquiries. Practices without them spend weeks reconstructing a year they should have recorded as it happened, and every gap gets read in HMRC’s favour, not theirs.
What triggers an HMRC enquiry into a dental practice?
Usually a figure that looks out of step with what is typical for that type and size of practice. Margins that do not sit right, a sharp swing in costs year on year, or private income that looks low against the number of surgeries in use. HMRC then asks for the records behind the numbers. Practices with clean, current records tend to have short uneventful enquiries. Those without spend weeks reconstructing records with every gap read in HMRC’s favour.
Does Making Tax Digital apply to my dental practice?
Most self-employed dental associates and sole-trader practice owners over the income threshold are affected, with the rules phasing in by income band over the next two years. For exact thresholds, submission dates and what to do next, see our Making Tax Digital guide.
What accounting software is best for a dental practice?
Xero is the most widely used in UK dentistry for practices and groups. QuickBooks works well for associates and smaller practices. Both are MTD-compatible. The right choice depends on the size and structure of the practice. Our bookkeeping article covers the comparison in full.

Manual associate pay takes 3-5 hours per practice per month – and up to 15 days for larger groups.
The most common errors are lab invoices going to the wrong associate and incorrect percentage calculations.
Samera AI connects directly to Dentally and Xero – your deduction rules go in once and the calculation runs itself.
Your finance team still reviews and approves the output, it just takes 30 minutes instead of hours.
Associates who can see how their pay was calculated raise fewer queries and are less likely to lose trust in the practice.
Three to five hours. Every month. Just to figure out what your associates are owed.
If that sounds familiar, the spreadsheet, the PMS export, the lab invoices spread across your desk, the formula you are terrified to touch, then you already know why automating dental associate pay is not a nice-to-have. For most UK practices, it is embarrassingly overdue.
This article covers why the manual process exists in the first place, what it is actually costing you beyond the hours, how AI associate pay automation works in practice, and what to look for when you are ready to do something about it.
Why Dental Associate Pay has Always Been Calculated Manually
Ask anyone who has done it, dental associate pay is nothing like running a standard payroll. With a salaried employee, the number is fixed. The payroll system knows it, applies it, done.
Associate pay is a different animal entirely, it moves every month, it is built on production or collections figures, and it gets adjusted by a set of deductions that vary not just between practices but sometimes between individual contracts within the same practice.
And the data you need to build that calculation? It is scattered across at least four different places. Production figures live in the practice management system. Payments and collections live in the accounting software. Lab invoices land from external suppliers and need to be manually matched to the right associate. Card processing fees sit in a separate terminal report. None of these talk to each other. You pull them all, line them up, and start reconciling, by hand, every time.
Then there is the deduction logic, which is where things get really practice-specific. A private practice might split lab fees 50/50 with the associate. An NHS practice has UDA targets baked into the calculation that directly affect what the associate takes home. A mixed practice is dealing with both simultaneously. Some contracts have an overhead contribution on top. Some do not. There is no standard formula that works everywhere, there is just yours, rebuilt from scratch each month.
“The reason there hasn’t been a proper software solution for associate pay until now is that the data for all of this sits in different systems. Lab bills sit in one system, clinical treatment data sits in another, and never the two are sitting together. Our job has been to bring all of that data into one integrated platform and then do the associate pay from there.”
Arun Mehra Samera CEO
The spreadsheet filled the gap because nothing better existed. It was free, it was flexible, and for a single-associate practice it more or less did the job. But it was never built for this. One associate – manageable. Five – you are one bad formula away from a problem. Multiple sites – it stops being a spreadsheet and starts being a liability.
Trupti Darekar, Client Accountant at Samera, works through these calculations with dental practices every month. She sees the same mistakes repeatedly.
“The major errors we see are wrong lab bills going to the wrong dentist, and wrong calculations of the percentage. Those two things come up again and again with clients.”
Trupti Darekar Samera Client Accountant
Both come from the same place, a process held together manually that was never designed to be manual. A lab invoice tagged to the wrong associate quietly reduces one person’s pay and inflates another’s. A percentage that has shifted in the spreadsheet, by a decimal, by an accidental keystroke runs uncorrected for months until someone notices the numbers do not feel right.
What Manual Associate Pay is Costing Your Dental Practice
Most practice owners think of associate pay as a time problem. It is that but the hours are honestly the least of it. The costs that do not show up on a profit and loss are the ones that hurt more- the associate who quietly stops trusting you, the dispute that escalates before anyone realises how it started, the practice manager who spends every month end doing financial admin instead of actually managing the practice.
Start with the time. Samera’s benchmark for a typical single-site UK dental practice is four to five hours per month on manual associate pay calculations. For groups, that number does not scale linearly, it explodes.
“I was speaking to a group last week with about 40 practices, and they told me it takes them between 10 and 15 days just to get associate pay done and they consider themselves quite organised. Information is coming from different locations, lab bills from another, everything sitting in different pots. It’s just not organised.”
Arun Mehra Samera CEO
Ten to fifteen days. Per month. For a task that should take minutes. And that is at a well-run group. The time your practice manager spends rebuilding that spreadsheet is time they are not spending on patient relationships, team development, or anything else that actually moves the practice forward.
The error cost is harder to put a number on and considerably more damaging. An underpaid associate loses trust immediately. An overpaid one has to be asked to hand money back, which is uncomfortable at best. Let it run for a few months without anyone noticing and you are no longer having an awkward conversation, you are potentially having a legal one.
“We have seen cases with clients where associates haven’t been paid correctly for months. By the time lawyers get involved, it is messy, expensive, and just draining mentally for everyone. And often it started with a spreadsheet error that nobody caught.”
Arun Mehra Samera CEO
Good dental associates are not easy to find and not easy to keep. They talk to each other, they compare notes, and a practice with a reputation for pay errors even an informal one, passed around at study clubs will feel that in recruitment and retention long before it shows up anywhere official.
“If pay is continually calculated wrong, people stop trusting the practice owner. That has a knock-on effect on motivation, and then people decide they don’t want to stay. If you have a system that’s transparent, where the associate can see exactly how things have been calculated that only helps the situation.”
Arun Mehra Samera CEO
Pay is personal. Getting it wrong once is a mistake. Getting it wrong repeatedly is a statement about how your practice operates and most associates will reach that conclusion long before they say anything out loud.

Let’s be clear about what automation actually means here because “AI” gets thrown around a lot and it is worth being specific. When it comes to automating associate pay, AI is doing something specific. It means replacing the parts of the process that eat your time and introduce errors, the exports, the cross-referencing, the formula-wrangling with a system that handles all of that in the background. Your finance team still signs off. They just stop building from scratch every month.
Before anything runs, Samera AI pulls two years of historical data from both Dentally and Xero and checks it properly. This is not a glamorous step, but it is arguably the most important one. No two practices use these systems in exactly the same way, so the platform needs to confirm the data is clean, consistent, and actually usable before it starts making calculations with it.
“Everyone uses Dentally differently, everyone uses Xero differently. So we want to pull two years of historical data from both systems first, check the integrity, make sure it’s clean and usable. Once we’ve done that, we can then do the associate pay month by month and know that the data we’re working with is reliable.”
Arun Mehra Samera CEO
Step 1: Connect your practice management system
Dentally connects directly to Samera AI via a live integration. Production data, broken down by associate and by period comes through automatically. No exports, no transfers, no copying anything anywhere.
Samera AI connects your practices directly. Each site shows its platform connection status and can be managed from a single view.
Step 2: Connect Xero
Same process for the accounting side. Collections data and payment information sync automatically, so the platform always has a current picture of what has been billed and what has actually landed.
Step 3: Configure your deduction logic, once
This is where your practice’s specific rules get built in. Lab fee splits, card processing deductions, NHS UDA adjustment rules, any overhead contributions in your associate contracts, it all goes in once. After that, the system applies it every month without anyone touching it. No re-entering, no re-checking, no “wait, which version of the spreadsheet has the right percentages?”
Step 4: Month-end calculation runs automatically
At month end, the platform calculates dental associate pay using the data it has already pulled and the rules it already knows. There is no formula to maintain, no reconciliation to run manually, no opening last month’s file and hoping nothing has drifted.
Step 5: Your team reviews and approves
A consolidated report lands for each associate, production, collections, every deduction itemised, net pay. Your finance team’s job is to review it and approve, or query a specific line if something looks off. A process that used to take four or five hours typically takes under 30 minutes at this stage.
The report your finance team reviews each month. Income, costs, gross profit, and net profit broken out by period. Select any line to drill down to the underlying transactions.
Pay slips go directly to associates from within the platform, with every line item visible. They can see exactly how their number was reached, which production figure, which deductions, what the net represents. That transparency on its own cuts down associate queries significantly, and those queries are a time cost most practices never think to measure.
“For us, associate pay is literally the first one per cent of where we’re going with Samera AI. Whilst we’re solving this problem, it opens up a whole range of other data that helps us understand the business better and provide further insight and advice to our clients on top of it.”

Manual vs Automated Dental Associate Pay: A Side-by-Side Comparison
The table below maps the manual process against the automated one, stage by stage. If you are still running dental associate pay on a spreadsheet, read each row and be honest with yourself about which column you are living in and what it is costing you to stay there.
Area
Manual (spreadsheet)
Automated (Samera AI)
Gathering data
Hours of CSV exports from your PMS and accounting software manually stitched together each month
Instant, automatic sync from Dentally and Xero, no exports, no copy-paste, no manual transfers
Calculations
Fragile spreadsheet formulas, one wrong cell cascades silently across every associate’s pay
Logic configured once, applied identically every month, no formula maintenance required
Lab fee deductions
Cross-checked by hand against paper or emailed invoices, easy to misallocate or miss entirely
Auto-reconciled against pre-set deduction rules, allocated to the correct associate every time
Accuracy
High error risk particularly when last month’s file is used as a template without full review
Consistent and fully auditable, every figure is traceable to its source data
Associate transparency
Hard to explain to associates when queried, ‘the spreadsheet says so’ is not a satisfying answer
Every line item is visible and traceable, associates can see exactly how their pay was calculated
Scalability
Time and error risk multiply with every new associate or additional site
The same logic handles 50 sites as easily as one, no rebuild required as the group grows
Month-end time
3–5 hours per practice, every month, more for groups with multiple sites
The finance team reviews and approves a completed report, typically under 30 minutes
Dispute resolution
Tracing errors requires going back through spreadsheet versions, time-consuming and often inconclusive
Every calculation is logged and auditable, disputes are resolved in minutes, not days
Look at the dispute resolution row. That one tells you everything. When something goes wrong in a manual process, you are not just fixing a number you are going back through multiple versions of a spreadsheet, trying to reconstruct a calculation that was built at month end when everyone was under pressure and nobody was being as careful as they should have been.
It can take days. With an automated system, every figure is logged from the moment it enters the platform. You can trace any number back to its source in minutes, not days. That is not a minor convenience, for a practice that has ever had an associate dispute a pay figure, it is transformative.
“What makes the AI software superior is speed. They don’t actually have to do anything – it just does it. Assuming everything has been set up correctly and the bookkeeping is in order, the time saving is instant. Speed and accuracy. Those are the two things people notice first.”
Trupti Darekar Samera Client Accountant
Choosing Dental Associate Pay Software: What to Look For
Dental associate pay software is a young category, which means the market is still a bit of a mixed bag. Some tools that call themselves automation still need you to export a file manually and upload it at which point all they are doing is applying a formula to data you have already pulled yourself. That is a neater spreadsheet with a nicer interface. It is not automation. Here is what to actually look for.
Does the provider understand dental practice?
This is the question that matters most, and it should come before any conversation about features or pricing. General payroll software – Sage, Xero Payroll is built for employees on fixed salaries. It has no concept of production-based pay, no understanding of lab fee deduction structures, no awareness of NHS UDA targets or how they affect what an associate actually takes home. “Dental-specific” should mean built from the ground up around how UK associates are paid not a generic tool with a dental logo on the login page.
“The most important question to ask any provider is: do the people who developed this actually know how dental practices work? Do they understand the problems practices face day by day, week by week? The key is to solve real problems not just provide fancy dashboards.”
Arun Mehra Samera CEO
Is the integration genuine?
If getting your data into the platform requires you to export a CSV from your PMS and upload it manually, the fundamental problem has not been solved it has just been moved one step along. What you need is a direct, live connection between the platform and both your practice management system and your accounting software. That is the difference between actual dental associate pay automation and a slightly more organised version of what you are already doing.
Can it handle your deduction logic specifically?
This is where a lot of platforms fall short. NHS UDA calculations, private fee splits, lab fee arrangements, card processing deductions none of these are standard. They vary between practices, and often between individual contracts within the same practice. Do not let any provider show you a generic demo and assume it covers your setup. Ask them to walk through your actual rules. If the answer involves manual workarounds, keep looking.
Will it still work when you grow?
A platform that handles three associates at one site reasonably well is not necessarily going to cope with fifteen associates across four sites without your finance team having to rebuild the configuration from scratch each time. If growth is on the cards even loosely make sure the system was designed for it. The efficiency gains from automating dental associate pay compound as a group scales, but only if the infrastructure was built to scale with you.
What does the associate actually see?
This one gets overlooked more than it should. An associate who receives a clear, itemised pay summary every deduction explained, every figure traceable is an associate who raises fewer queries, trusts the process, and is less likely to quietly start wondering whether they are being paid correctly. A platform that produces a pay slip your associates can actually understand is not just good for relationships. It saves your practice manager time every single month.
How does it handle your data?
Associate pay means sensitive financial data. In practices connected to Dentally, it means data that sits close to patient records. Any third-party platform handling this needs to be GDPR-compliant and storing data on UK-based servers, not just claiming to be compliant in the small print. Ask directly, and if the answer is vague, that tells you something.
“When choosing any associate pay platform, make sure the provider has all the necessary credentials, that they’re GDPR compliant and that the data sits on servers based in the UK. That’s an important aspect from a cybersecurity and data protection point of view.”
Arun Mehra Samera CEO
One thing worth being clear about before we move on: Samera AI is not a payroll system. It does not deal with PAYE, employer National Insurance, or any of the tax obligations that come with employing staff, your existing payroll provider handles all of that. What Samera AI does, specifically, is calculate what each self-employed associate is owed each month. Accurately, consistently, and with a full audit trail so that if anyone ever questions a figure, the answer is already there.
Stop Calculating Dental Associate Pay Manually
Four hours a month. Every month. On a calculation that should take minutes.
If that is where you are, whether you are a single-site practice nursing a spreadsheet or a growing group where associate pay is eating days of your finance team’s time, it is not going to fix itself. The data is not going to start talking to each other on its own.
The formula is not going to stop breaking. The associates are not going to stop calling.
Samera AI is the UK’s first automated associate pay platform built specifically for dental practices and groups. It connects directly to Dentally and Xero, applies your deduction logic automatically, and produces a clear, itemised pay summary in minutes, for one associate or fifty.
How long does it take to automate dental associate pay with AI?
Less time than you probably think. The initial setup- connecting Dentally and Xero, building in your deduction logic, running the data audit takes a few hours with Samera AI support. After that, the monthly calculation runs on its own. Most practices go from spending four to five hours a month on this to spending twenty or thirty minutes reviewing a report that is already done.
Can AI handle different deduction rules for different associates?
Yes – and this is exactly where a dental-specific platform earns its place. Samera AI applies deduction logic on an associate-by-associate basis, so different lab fee splits, different NHS UDA adjustments, different overhead contributions, different percentage arrangements can all be configured separately. Set the rules once per associate and the system applies them consistently every month without anyone checking or re-entering them.
Is automated dental associate pay GDPR compliant?
It should be – but “should be” is not good enough when you are connecting a platform to your PMS and accounting software. With Samera AI, data is stored on UK-based servers and the platform is GDPR-compliant. Before signing up with any provider, ask them directly about data residency and security credentials. If the answer is vague or buried in a privacy policy, that is worth paying attention to.
What is the difference between associate pay software and payroll software?
They solve completely different problems. Payroll software like Sage or Xero Payroll is built for employees – people on fixed salaries, with employer tax obligations, National Insurance contributions, and PAYE attached. Dental associate pay software is built for self-employed associates whose pay changes every month based on what they produced, what was collected, and what deductions apply under their contract. Associates handle their own tax. The two categories are not interchangeable, and trying to use one to do the other’s job is where a lot of practices run into trouble.
Does Samera AI work for NHS practices as well as private?
Yes. NHS UDA-based deduction logic, private percentage splits, and mixed-practice arrangements can all be configured within the platform. UDA targets and NHS adjustment rules are built in on a practice-by-practice basis, so NHS associate pay runs through the same automated process as private – correctly calculated, every month.
At what point should a dental practice consider automating associate pay?
Honestly? The moment it starts feeling like a chore. For most practices that is somewhere around two or three associates, when the spreadsheet starts needing real maintenance and the margin for error starts feeling uncomfortable. If your finance team is spending more than an hour a month on this, or if you have had even one pay dispute or miscalculation, the case is already there. For groups with multiple sites, the question is not really whether to automate, it is why you have not done it yet.

Running a dental group is a fundamentally different challenge from owning a single practice. The tax picture is more complex, the compliance obligations are heavier, and there are more areas where HMRC looks closely. At the same time, the planning opportunities available to groups are considerably greater than those available to single-site owners.
Group structures and why the holding company model tends to work best.
EBITDA: what it is, why it matters for day-to-day management, and how to improve it.
Management charges and transfer pricing between group entities.
Group relief: offsetting losses in one company against profits in another.
VAT across multiple sites, capital allowances coordination, and succession.
Key Takeaways
Group accounts are almost always in poor shape when they first arrive with a specialist – a holding company structure only delivers its tax advantages if the accounting behind it is done properly from the start.
EBITDA is the figure buyers and lenders actually value the group on, but the calculation method needs to be consistent and verified – inconsistent methods across group companies undermine buyer confidence before negotiations even start.
Intercompany management charges need a written agreement and a documented basis of calculation – HMRC doesn’t need to prove the amount is unreasonable, only that the paperwork doesn’t exist.
Group relief can offset losses in one company against profits in another, but only where the 75% ownership test holds throughout the accounting period – acquisitions and restructuring can break it without anyone noticing.
Most actively trading dental companies qualify for Business Property Relief, but holding significant non-trading assets within the group structure can put that relief at risk.
What dental group accounts actually look like when they arrive
Natasha Gnanapragasam, Director of Operations, Accountancy and Tax at Samera, has reviewed group accounts from dental practices across the UK. Her assessment of what she finds is direct:
“All the groups are a mess. None of the groups I have ever seen, when they came to us, had their accounts in good shape. It was always a mess. So we do it properly once they’re with us. But that’s the reality of what we find. Group accounting is complex enough that without a specialist handling it from the beginning, it rarely gets done correctly.”
If your group’s accounts are anywhere close to what Natasha describes, a specialist team built specifically for multi-site dental groups can bring order to it properly, not just patch over the mess year after year.
Most dental groups that have been set up well use a holding company with trading subsidiaries beneath it. The parent company owns the shares in several trading entities, each running one or more practice sites. This model tends to work best for several reasons:
Cash can be moved to the holding company through dividends and reinvested or extracted more efficiently.
Selling one practice means selling that subsidiary rather than restructuring the entire group.
A problem at one site is less likely to affect the others when they sit in separate legal entities.
Banks, investors, and buyers generally find a clear holding structure easier to work with.
Some groups instead run as a single trading company owning several sites, which is simpler day to day but leaves every site’s assets exposed if problems arise at any one location. Others rely on a mix of employed dentists and self-employed associates without a formal group structure at all, which works at a small scale but creates contract and payroll complexity as the group grows. For most groups beyond two or three sites, the holding company model’s risk separation and sale flexibility outweigh the simplicity of the alternatives.
Where HMRC looks closely in dental groups
VAT across all sites. Clinical work is exempt; cosmetic and retail services are generally taxable. Groups with multiple sites must keep these income streams clearly separated at every location, not just at group level – a single site blending exempt and taxable income without proper records can distort the whole group’s partial exemption calculation, not just its own figures.
Employment status of associates. HMRC looks at the actual working relationship, not the contract label – control, fixed hours, and whether a genuine substitute is allowed all matter. Because most groups use one standard contract across every site, a single flawed clause can create PAYE and NI exposure at every location at once, not just one.
Intercompany transactions. Management fees, internal loans, and service charges must be commercial, documented, and priced at arm’s length. HMRC doesn’t need to prove a charge is unreasonable to challenge it – missing documentation alone is enough to create a problem, which is why the paperwork behind every intercompany arrangement matters as much as the pricing itself.
Corporation Tax for dental groups
Each company in the group pays Corporation Tax on its own taxable profits, calculated separately even where a holding company structure links them. The UK’s tiered rate structure means smaller companies benefit from a lower rate, with a higher rate applying above a certain profit threshold and marginal relief in between – check current rates and thresholds on gov.uk, as these are reviewed with each Budget.
This has a practical consequence for groups specifically: profits sitting in several smaller trading subsidiaries can be taxed differently than the same total profit concentrated in one larger company, depending on where the thresholds fall. How profits are distributed across the group – and whether they’re retained, moved to the holding company as dividends, or extracted personally – is worth reviewing with your accountant as the group grows, rather than assuming the structure that worked at two sites still works at ten.
How profits are distributed across your group’s subsidiaries – and whether they’re retained, moved to the holding company, or extracted personally – is worth reviewing regularly, not just when the structure was first set up. Our tax planning team works through this with growing groups as circumstances change.
EBITDA: what it is and why it matters before any sale
EBITDA stands for Earnings Before Interest, Tax, Depreciation, and Amortisation. It is the figure buyers, lenders, and investors use when valuing a dental group. It strips out financing costs, depreciation, and non-cash entries to show the underlying trading performance of the business.
A clear, consistently calculated, and well-documented EBITDA figure also makes due diligence considerably faster once a sale process starts – buyers and their advisers spend less time querying the numbers and more time negotiating on them.
Natasha on the most common reason an EBITDA figure turns out to be unreliable:
“When they calculate EBITDA, different people might have different calculation methods. So we need to revisit that and ensure whether they have excluded or included the proper elements. That’s what we find, the calculation method hasn’t been consistent or correct. Before a sale or any valuation conversation, we go back through it and verify every line.”
Natasha Gnanapragasam Director of Operations
Improving EBITDA practically
Centralise finance, HR, and purchasing across the group to benefit from economies of scale.
Standardise associate contracts so pay drift across sites is managed consistently.
Improve chair utilisation and case acceptance rates.
Grow higher-margin private treatment streams while monitoring the VAT position on cosmetic work.
Negotiate group-wide lab and supplier contracts using combined purchasing volumes.
Remove genuine one-off costs from adjusted EBITDA so the figure reflects ongoing trading performance.
Centralising finance and HR, standardising contracts, improving chair utilisation – these are exactly the areas our growth team works through with dental groups, whether you’re building toward a sale or just want stronger underlying performance.
Management charges and transfer pricing between group entities
Most dental groups have a holding company or central services entity charging the trading subsidiaries for finance, HR, marketing, IT, or management oversight. Done correctly this is legitimate and often tax-efficient. The documentation around how those charges are set is what HMRC scrutinises.
The arm’s length principle
Transactions between connected companies must be priced as if between two unconnected parties negotiating commercially. The management fee must reflect what an independent third party would charge for the same services.
Where groups fall down
Natasha on what the actual problem almost always is:
“Intercompany management charges, that’s one that’s not widely used correctly. The documentation is almost always missing. There’s a charge happening between entities, but there’s no written agreement, no basis of calculation. HMRC doesn’t need to find the amount unreasonable to create a problem, they just need to show the records don’t exist to support it.”
Natasha Gnanapragasam Director of Operations
What the documentation needs to include: a written intercompany agreement between the entities, a clear statement of what services are being provided and how the fee is calculated, payment terms, and evidence of the underlying costs. Review it at least annually. VAT applies to management charges between non-grouped entities.
Group relief and loss offsetting
Group relief allows a company in a qualifying group to surrender its current year trading losses to another company in the same group. To qualify, companies must meet the 75% ownership test: one company must own at least 75% of another, or both must be 75% owned by the same parent. Natasha on what proper allocation of losses actually requires:
“Group relief comes into play when one entity in the group has made a loss. It is really important that you allocate the losses properly. There is a specific rule that you need to apply in such cases. We look into that carefully and do it properly, because getting the allocation wrong means either losing the relief or creating a compliance issue.”
Natasha Gnanapragasam Director of Operations
Use losses from a new or struggling practice to offset profits in established profitable sites.
Plan major refurbishments so related costs and losses fall in the same period as group profits.
Check the 75% ownership test holds throughout the relevant accounting period after any acquisition.
Keep clear records of exactly how each loss surrender was calculated and agreed between the companies involved – the same documentation discipline that applies to management charges applies here.
Group relief for Corporation Tax and VAT grouping are entirely separate regimes, despite the shared terminology – qualifying for one says nothing about your position under the other, and each needs its own separate assessment.
The basic VAT position is the same as for a single practice, but managing it across multiple sites adds complexity that single-site owners do not face.
Mixed supplies across several locations can create partial exemption positions that need to be calculated for the group as a whole.
VAT grouping can simplify intercompany supply arrangements but must be weighed against the partial exemption implications.
Management fees between non-grouped entities may create VAT obligations.
Clinical notes and separate invoices for cosmetic work must be maintained at every site.
Undocumented intercompany charges are a governance problem as much as a tax one. If ongoing company secretarial and compliance oversight across your group’s entities would help, that’s exactly what this service covers.
The AIA operates at individual company level. Each entity in the group has its own limit rather than sharing one across the whole group. Coordinate major equipment purchases across all companies so each entity’s AIA is used efficiently. Only the company that owns an asset can claim the allowance on it.
Construction costs and certain qualifying building improvements may also be eligible for the Structures and Buildings Allowance, a separate relief from the AIA that covers non-residential buildings rather than plant and machinery. This is particularly relevant for groups fitting out new sites or carrying out significant refurbishment work – check whether your specific costs qualify before assuming they fall under AIA alone.
Succession is considerably more complicated for a multi-site group than a single practice – shares are often held across founders, senior managers, and sometimes outside investors, and without clear planning in place, a death, illness, or retirement can quickly become disruptive to both the people involved and the value of the business.
Business Property Relief can provide full Inheritance Tax relief on qualifying business assets, and most actively trading dental companies qualify. Relief can be lost, however, for parts of the group that hold investment property or shares in non-trading companies – worth checking specifically where the group holds any assets beyond the trading practices themselves.
A properly drafted and current shareholders agreement is the foundation of group succession planning. It should address what happens on death, incapacity, or retirement, including pre-emption rights, how the business will be valued, and the transfer process. Beyond the agreement itself, groups also use staged share gifting to manage Inheritance Tax exposure over time, management buy-outs or phased exits to preserve continuity, and trusts or wills to ensure shares pass to the right people with minimal disruption.
Clean, consistent reporting across every entity in the group is the foundation succession and sale planning both depend on. Our financial infrastructure build is designed specifically for groups preparing for a refinance, raise, or sale.
The structure only works if the numbers behind it are right
Everything covered here – the holding company model, EBITDA, management charges, group relief, VAT, and succession – comes back to the same underlying requirement: a group structure only delivers its advantages when the accounting and documentation behind it are done properly, not assumed to be fine because the structure itself looks right on paper. An unreliable EBITDA figure, an undocumented management charge, or a shareholders agreement nobody’s updated in years can each undo value the structure was supposed to protect.
None of this gets easier by waiting. Group accounting complexity grows with every site you add, and the groups that get this right are the ones reviewing it continuously, not scrambling to fix it before a sale or a succession event forces the issue. Use this article as your starting point, then speak to a specialist who works with dental groups specifically, so the structure you’ve built is actually supported by the records behind it.
Group tax planning only works when the accounting behind it is done properly – structures, EBITDA, management charges, and succession all depend on it. Find out how we work with dental groups specifically, from the accounts up.
One company must own at least 75% of another, or both must be at least 75% owned by the same parent. The test must hold throughout the relevant accounting period. Acquisitions and ownership restructuring can break it, always check before planning any group relief claims.
How should management charges be set between group entities?
At arm’s length, meaning the fee must reflect what an independent third party would charge for the same services. It must be supported by a written intercompany agreement, documented against real underlying costs, and reviewed at least annually. VAT applies to charges between non-grouped entities.
How does EBITDA affect a dental group’s valuation?
Buyers apply an earnings multiple to adjusted EBITDA to arrive at a valuation. A higher, cleaner, better-supported EBITDA figure produces a higher valuation. Inconsistent calculation methods across group companies or poorly documented adjustments reduce buyer confidence and the multiple they are prepared to pay.
Can dental practices qualify for Business Property Relief?
Most active dental trading companies qualify, provided they are predominantly trading rather than holding investments and the two-year ownership test is met. Relief can be lost if significant non-trading assets such as investment property or substantial cash reserves are held within the structure.
Does Corporation Tax work differently for a group than a single practice?
Each company in the group pays Corporation Tax separately on its own profits, even within a holding company structure. Because the UK’s tiered rate system applies per company, how profits are distributed across subsidiaries can affect the overall tax outcome – worth reviewing as the group grows rather than assuming an early structure still works at scale.
What is the Structures and Buildings Allowance and how is it different from the AIA?
It’s a separate relief covering non-residential buildings and qualifying construction or improvement costs, rather than plant and machinery. It’s particularly relevant for groups fitting out new sites or carrying out significant refurbishment – check whether specific costs qualify rather than assuming they fall under the AIA.

Running a dental practice through a limited company brings better tax efficiency and personal asset protection than operating as a sole trader, but understanding the essential taxes for dental practice owners means getting to grips with a more complex set of obligations – Corporation Tax, VAT, and capital allowances chief among them.
Corporation Tax: how it works and how practice decisions affect it.
The director’s loan account: what it is, when it goes wrong, and how to keep it clean.
VAT in dentistry: the unusual exempt position, what is actually taxable, and partial exemption.
Capital Gains Tax, Business Asset Disposal Relief, and Stamp Duty Land Tax when buying or selling.
Capital allowances: the most underused tax relief in dental practice.
Key Takeaways
Corporation Tax is charged on the company’s profits, but salary, dividends, and pension contributions all interact with it differently – the right mix changes as rates and profits change.
An overdrawn director’s loan account is the most common problem limited company owners run into, and it often develops without anyone realising until the accounts are prepared.
Most clinical dental work is VAT-exempt, not zero-rated – a distinction that matters, since exempt practices generally can’t reclaim VAT on their own purchases.
Business Asset Disposal Relief can make a significant difference to the tax on a sale, but only if the structure and eligibility are confirmed well before the sale, not during it.
Capital allowances let most equipment purchases be deducted in full in the year of purchase – but every asset type has its own rules, so it’s not one calculation fits all.
Corporation Tax
What it is and how it works
If your practice operates as a limited company, the company pays Corporation Tax on its taxable profits. This includes income from clinical work after deducting allowable expenses, rental income from rooms let to associates, and any gains from selling assets. The UK uses a tiered structure with a lower rate for smaller profits and a higher main rate above a certain threshold, with marginal relief in between. For current rates and thresholds, check the HMRC website.
Salary versus dividends. Most practice owners take a modest salary and draw additional income as dividends. Dividends do not reduce company profits for Corporation Tax purposes, but the combined personal tax on a salary-plus-dividend mix is typically lower than taking everything as salary. Dividend rates can change, which shifts the optimal balance. Review this with your accountant annually.
Employer pension contributions. Pension contributions the company makes on behalf of directors reduce taxable profits before Corporation Tax is applied and are not taxed as personal income at the point of contribution. In our experience this is one of the most consistently underused reliefs available to practice owners.
Timing of expenditure. Buying equipment or completing qualifying refurbishment before your accounting year-end reduces taxable profits for that period. Worth planning alongside capital allowances strategy.
Getting the salary, dividend, and pension mix right takes ongoing review, not a one-off decision. Our tax planning team works through this with practice owners annually, so the balance keeps pace with rate changes rather than falling out of date.
This is the area that catches limited company practice owners off guard most often. Natasha Gnanapragasam, Director of Operations, Accountancy and Tax at Samera, describes the most common problem she encounters:
“The most common issue is an overdrawn director’s loan account balance. Directors borrowing into an overdrawn position, that is what we see most frequently. And it almost always develops without the client realising it has happened, because nobody is watching it in real time.”
Natasha Gnanapragasam Director of Operations
The director’s loan account records all money that passes between you personally and the company outside of formally declared salary or dividends. When it goes overdrawn, meaning you have taken more out than you have put in, two specific tax problems arise.
First, if the overdrawn balance is not repaid, formally written off, or declared as a dividend within nine months and one day of the company’s accounting year-end, the company pays a tax charge to HMRC on the outstanding amount – known as Section 455 tax. This can be significant for what is essentially a record-keeping issue. If you repay the loan later, you can reclaim the charge, but the cash flow impact in the meantime is real.
Second, if the outstanding loan exceeds £10,000 at any point during the year, it is treated as a benefit in kind. You pay Income Tax on a notional interest charge and the company pays National Insurance on it. Not catastrophic, but an avoidable cost.
The simplest prevention: make sure any money you draw from the company is formally categorised as salary or dividends at the time rather than informally taken and sorted out later. Your accountant should be reviewing the loan account quarterly. If they are not, ask them to start.
An overdrawn director’s loan account is usually a governance problem as much as a tax one – nobody’s watching it in real time. If ongoing company secretarial and compliance oversight would help, that’s exactly what this service covers.
The dental VAT position is genuinely unusual and is misunderstood more often than it should be. Most clinical dental treatment is exempt from VAT, not zero-rated but exempt. That distinction matters: zero-rated businesses can reclaim input VAT on their purchases; exempt businesses generally cannot. The VAT paid on lab fees, equipment, and supplies is a real cost for exempt dental practices.
What is VAT-exempt in dentistry
Dental services performed by a registered dental professional where the primary purpose is protecting, maintaining, or restoring a patient’s health are generally VAT-exempt. This covers the vast majority of NHS work and most private clinical treatment.
What is not VAT-exempt
Purely cosmetic procedures where there is no clinical or health justification.
Product sales including whitening kits, toothbrushes, and oral care products.
Non-clinical training courses or consultancy services sold to other practices.
The line between clinical and cosmetic is not always obvious. HMRC allows flexibility: where a cosmetic element forms part of a treatment that is primarily for health reasons, the whole treatment may remain exempt. What is documented in patient notes matters.
Partial exemption
Practices providing both exempt and taxable services become partially exempt. Input VAT recovery is limited to the proportion relating to taxable activities, calculated using an approved method. Getting partial exemption calculations wrong creates problems in both directions. For any practice with meaningful cosmetic or retail income, specialist VAT advice pays for itself.
Getting VAT-exempt and taxable income properly separated matters even more once digital reporting requirements apply to your practice. Find out what Making Tax Digital actually means for a partially exempt dental business.
Capital Gains Tax and Business Asset Disposal Relief
CGT can arise when you sell goodwill, sell shares in the company, or sell practice property. The structure of the sale determines who pays it and how it is calculated. Natasha on what the difference between qualifying and not qualifying for BADR actually means financially:
“When BADR applies, it will be 10%. But if it hasn’t been applied, they would pay either 24% or 18%, depending on the nature of the sale and the tax bracket they fall into. That is a very significant difference, and it is why the structure and BADR eligibility need to be confirmed well before any sale is agreed.”
Natasha Gnanapragasam Director of Operations
Timing matters beyond just the sale structure itself. Extracting funds from the company shortly before a sale – through an unusually large dividend or a lump pension contribution timed to coincide with completion – can trigger unnecessary tax if it’s not planned properly well in advance. Any pre-sale extraction should be planned as part of the same process as confirming your BADR eligibility, not treated as a separate, later decision.
The BADR rate and qualifying conditions have changed in recent years and further changes are scheduled. Always verify the current position before planning any sale.
Stamp Duty Land Tax applies when you buy freehold or leasehold commercial premises, charged in bands on the purchase price rather than as a flat percentage. It’s a separate cost from CGT and applies at the point of purchase, not sale – worth factoring into the total cost of buying a practice property, not just the headline price. If you’re considering moving property between personal and company ownership, model the SDLT cost carefully before acting, since a transfer between the two can itself trigger a charge.
Stamp Duty Land Tax is one of several costs that catch buyers out if it’s not factored in early. Our practice acquisition process covers this alongside financing, structure, and due diligence, so nothing surprises you at completion.
Capital allowances are the main mechanism for claiming tax relief on equipment, technology, and some property improvements in a dental practice. Natasha on why getting this right requires understanding each asset’s specific rules:
“When they purchase equipment and capital assets, it is really important that they record those correctly for capital allowances. Every different asset has different rules when it comes to claiming tax relief. You need to understand the nature of each asset and what rule applies, then apply the correct percentage to claim the capital allowances. It is not one size fits all.”
Natasha Gnanapragasam Director of Operations
The Annual Investment Allowance allows 100% of qualifying plant and machinery costs to be deducted in the year of purchase, up to the annual limit. For dental practices this covers dental chairs, X-ray machines, CBCT scanners, CAD/CAM systems, autoclaves, sterilisation equipment, IT hardware, and certain surgery fit-out costs. The current limit is £1 million per year. Check the HMRC website before planning significant expenditure around it.
Some qualifying purchases may also be eligible for First Year Allowances or full expensing, which offer enhanced upfront relief beyond the standard AIA rules on certain types of expenditure. Eligibility depends on the asset type and the timing of the purchase, so check current criteria on gov.uk before assuming a purchase qualifies.
If the practice sits within a holding company or group structure, this can help manage sale proceeds efficiently and make use of available group reliefs – but it needs to be arranged correctly well ahead of any transaction. A holding company structure that hasn’t been set up properly creates its own risks, including the kind of director’s loan account and Section 455 tax problems already covered in this article, so this is not a step to take without specialist advice specific to your situation.
When a practice owner comes to Samera planning a sale, Natasha describes what the firm does first:
“The first thing we look into is the structure. If they don’t have a proper structure before they sell the practice, we recommend they put a proper structure in place first. That step has to happen before the sale process begins, not during it. Most of the tax planning opportunities are connected to having the right structure well ahead of any transaction.”
BADR eligibility, pre-sale extraction timing, and structure all need to be right well before a buyer appears. Our sale process is built around getting this planning done early, not scrambling once a deal is on the table.
Practical tax planning checklist for practice owners
Running a dental practice through a limited company means more moving parts than a sole trader structure, but a small number of consistent habits keep most of them under control:
Review salary and dividend mix annually. The optimal split changes as rates and profits change.
Review the director’s loan account quarterly and ensure it does not go overdrawn without a formal dividend being declared.
Plan employer pension contributions before year-end.
Keep clear separate records for VAT-exempt and VAT-taxable supplies.
Monitor taxable turnover as it approaches the VAT registration threshold.
Plan significant equipment purchases around your accounting year-end.
If a sale is on the horizon, start planning at least two to three years ahead.
If a sale is on the horizon, avoid large dividends or lump pension contributions timed close to completion – plan any extraction alongside your BADR review, not separately.
Factor Stamp Duty Land Tax into the total cost of any property purchase, and model it carefully before moving property between personal and company ownership.
Getting the structure right matters more than any single tax rule
Every area covered here – Corporation Tax, the director’s loan account, VAT, a future sale, capital allowances – connects back to the same underlying point: the right structure, set up and maintained properly, is what makes each of these reliefs and rules work in your favour rather than against you. An overdrawn director’s loan account, a badly structured holding company, or a sale planned without confirming BADR eligibility can all turn what should be a straightforward tax position into an expensive one.
None of this needs to be complicated if it’s reviewed regularly rather than left until year-end or until a sale is already in motion. Use this article as your starting point, then speak to a specialist dental accountant who understands where these areas specifically go wrong in dental practices, so nothing gets missed and nothing gets structured incorrectly from the start.
Taxes for Dental Practice Owners: FAQs
What is a director’s loan account and when does it create a tax problem?
A director’s loan account records money that moves between you and the company outside of formally declared salary or dividends. When you owe the company money it is overdrawn. If an overdrawn balance is not cleared within nine months and one day of the accounting year-end, the company pays a tax charge to HMRC on the outstanding amount. Loans above £10,000 also create a benefit-in-kind charge.
Is all dental treatment VAT-exempt?
No. Clinical treatment for health reasons is generally exempt. Purely cosmetic procedures with no clinical justification may be taxable. Product sales and non-clinical services are typically standard-rated. The specific facts and clinical documentation determine the correct treatment for each case.
What is the difference between an asset sale and a share sale?
In an asset sale, specific assets are sold individually. The company pays Corporation Tax on gains above book value, and the owner pays further personal tax when extracting the proceeds. In a share sale, the buyer acquires the company itself and the seller pays Capital Gains Tax on the gain in share value. For most sellers, a share sale with BADR produces a significantly better after-tax outcome.
How far ahead should I plan a practice sale from a tax perspective?
At least two to three years. Confirming BADR eligibility, reviewing the company structure, planning pre-sale profit extraction, and deciding on the sale structure all require time. Planning that starts once a buyer appears is almost always less tax-efficient.
Do I need to pay Stamp Duty Land Tax when buying a practice property?
Yes, if you’re buying freehold or leasehold commercial premises. SDLT is charged in bands on the purchase price and is separate from any CGT that might apply later on sale. If you’re moving property between personal and company ownership, a transfer can itself trigger a charge, so it’s worth modelling before acting.
What are First Year Allowances and how are they different from the AIA?
First Year Allowances and full expensing offer enhanced upfront relief on certain types of expenditure, beyond the standard Annual Investment Allowance rules. Eligibility depends on the specific asset type and timing of the purchase, so it’s worth checking current criteria before assuming a purchase qualifies rather than relying on the AIA alone.
Is a holding company structure worth setting up before selling my practice?
It can help manage sale proceeds efficiently and make use of group reliefs, but only if it’s set up correctly well ahead of the transaction. A poorly structured holding company creates its own risks, including the same director’s loan account and Section 455 problems that affect any limited company. This isn’t a step to take without specialist advice specific to your situation.

Tax tends to be one of the less enjoyable parts of life as a newly self-employed dental associate, particularly in the first couple of years when nobody has explained how Self Assessment actually works, why HMRC wants money before you have technically earned it yet, or which specific expenses you are allowed to deduct.
Once you understand the basics it genuinely is not complicated. This article covers how associates are taxed, how Self Assessment works, which expenses reduce your bill, and how to approach pension planning as a self-employed professional.
How Self Assessment works for self-employed dental associates.
Payments on account, the part that catches almost every new associate off guard.
Which expenses reduce your tax bill and which do not.
Pension planning: the NHS scheme, private pensions, and how contributions cut your tax.
Key Takeaways
Tax is calculated on taxable profit, not gross income – every legitimate expense you claim reduces both your Income Tax and National Insurance bill.
Payments on account catch most new associates off guard – budget for them from month one, since a strong first year can mean paying your full tax bill and 50% of next year’s estimate on the same day.
The NHS Pension’s annual allowance is based on how much your pension has grown, not how much you’ve paid in – a strong earning year can push you over the limit even without extra contributions.
If you do exceed the annual allowance, Scheme Pays lets the NHS Pension Scheme settle the charge in exchange for a reduced future pension, rather than an unexpected lump sum bill.
Get proper documentation before claiming any relief, not just a verbal confirmation – unsupported claims can lead to HMRC investigations, penalties, and interest that dwarf the original tax saved.
What newly self-employed associates consistently get wrong
Natasha Gnanapragasam, Director of Operations, Accountancy and Tax at Samera, describes what the first conversation with a newly self-employed associate typically looks like:
“The most common problem is not understanding the tax, not understanding how the business works, how the tax is calculated, where the numbers come from. And one thing we hear constantly is that their previous accountant was not reaching out to them, not communicating properly. So once they come to us, we educate them. We make sure they understand their taxes, where those numbers come from, how everything is calculated. That’s how we differ. We explain it rather than just filing the return.”
Built specifically for self-employed dental associates, not adapted from a generalist package. Our associate accounts service covers your Self Assessment, expense claims, and pension planning, with an accountant who actually explains the numbers rather than just filing the return.
Most dental associates work as self-employed sole traders. You are responsible for recording your own income, tracking your business costs, and paying your own Income Tax and National Insurance through Self Assessment each year.
Your tax is not calculated on everything you earn. It is calculated on your taxable profit:
Taxable profit = Total income from all practices minus allowable business expenses
Both Income Tax and National Insurance are calculated on this profit figure, not your gross income. Claiming every expense you are legitimately entitled to reduces this figure and your bill along with it.
For current Income Tax bands and National Insurance rates, check the HMRC website. These change with each Budget and any specific figures in articles go out of date quickly.
Understanding how your tax is calculated is one thing – planning around it before the bill arrives is another. A specialist dental accountant can help you structure your expenses, pension contributions, and income properly throughout the year, not just file the numbers after the fact.
Self Assessment: registering and what the deadlines actually mean
If you are new to self-employment, register for Self Assessment with HMRC by 5 October in the tax year after you start working. HMRC issues a Unique Taxpayer Reference number, which you need for every return you file.
31st January: online Self Assessment deadline, plus any tax owed for the previous year.
31st October: paper return deadline. Almost everyone files online.
5th October: deadline to register if you are newly self-employed.
Missing the 31 January deadline triggers an automatic £100 penalty from the moment it passes, regardless of whether you owe any tax. Further penalties apply at three months, six months, and twelve months late. Interest runs on any unpaid tax from the due date.
Payments on account: the part nobody warns you about
This is the one that causes the most unpleasant financial surprises for newly self-employed associates, and it is almost always because nobody explained it in advance. Payments on account are advance payments towards the following year’s tax bill. HMRC calculates them as half of your previous year’s combined Income Tax and Class 4 National Insurance, due in two instalments.
You don’t need to make payments on account at all if your previous year’s tax and Class 4 NI bill was below a certain threshold, or if most of your tax was already collected at source. Check the current threshold on gov.uk, as it is periodically reviewed.
When payments on account are due
31 January – first payment on account, due on the same date as your final tax bill for the previous year. 31 July: second payment on account.
In a strong first full year of self-employment, you could be paying your full current tax bill in January plus 50% of the following year’s estimated bill on the exact same day. If you have not been setting money aside for this, it feels like HMRC is asking for money you simply do not have.
Natasha explains what can actually be done about it before the bill arrives:
“This is a common issue. What we do is estimate ahead for the next tax year, to see how the position looks, because that can have an impact on the payment on account. You can either reduce it, claim it from HMRC, or prepare to pay depending on how the following year looks. The point is to do a proper assessment rather than just letting the January bill land as a shock.”
Natasha Gnanapragasam Director of Operations
The practical fix is simple: set aside a percentage of your income every month into a separate savings account from the first month of self-employment. Your accountant can suggest a realistic percentage based on your expected annual profit. If you expect lower income next year, you can apply to reduce payments on account, but if you reduce them by too much and income turns out higher, HMRC charges interest on the difference.
Once your Self Assessment return is filed, HMRC works out your actual tax due for the year. If your payments on account didn’t cover the full amount, the shortfall is called a balancing payment, due on the same 31 January as your first payment on account for the following year – meaning that date can carry both at once. If you overpaid, the excess can be refunded or carried forward against future payments.
Keeping proper digital records isn’t just good practice – it’s becoming a legal requirement. Making Tax Digital for Income Tax means quarterly digital reporting to HMRC rather than one annual return, and it’s already reshaping how self-employed associates need to track their numbers. Find out whether it affects you yet, and get set up properly before it does.
Natasha describes one of the most expensive mistakes she has seen, not a penalty for a missed deadline but a misclaim that came from inadequate documentation:
“The most expensive case I’ve come across involved an investment relief called EIS relief. Things went wrong because they didn’t have adequate information before it was claimed. The client verbally said they had this investment, we put it in the letter of representation and claimed it based on what they told us. But it is really important that clients provide actual documents. Without them, the claim has no support. When it went to investigation with HMRC, they ended up paying a lump sum, penalty and interest charges on top of the tax. And those are hectic. HMRC charges very heavy interest. The most expensive thing I have seen is not the tax itself. It is the penalties and interest that follow when something goes wrong without proper records.”
Natasha Gnanapragasam Director of Operations
Expenses dental associates can claim
The rule from HMRC is consistent: the expense must be incurred wholly and exclusively for your dental work. For a full breakdown of what qualifies and what does not, see our dedicated article on dental expenses.
GDC registration fees, fully deductible each year.
Professional indemnity premiums, fully deductible.
CPD courses, dental conferences, and professional seminars.
Professional membership fees for the BDA, FGDP, RCS, and study clubs.
Dental loupes and clinical equipment, often claimable in full through the Annual Investment Allowance in the year of purchase.
PPE used clinically including scrubs, masks, visors, and gloves.
Mileage when travelling between two different practices on the same working day.
Accountancy fees for your Self Assessment return, itself a deductible expense.
The business proportion of phone and internet costs.
Use of home if you carry out dental administration from home.
Getting NHS income recording right
Natasha on how associates who combine NHS and private work typically get their income recording wrong, and what the downstream consequences are:
“NHS income has to be coded into particular codes in the bookkeeping, every element on an NHS statement has a specific code. If a bookkeeper or accountant doesn’t understand NHS statements, they won’t do that correctly. And if it’s not done correctly, you end up either paying over-tax or under-tax. Every element on that NHS statement has a nuance. This can only be done properly by a specialist. Not by a general accountant, not really, not to the same extent.”
NHS income coding, associate fee splits, mixed NHS and private work – these are exactly the details a specialist dental accountant handles correctly and a generalist typically doesn’t. See how we work with associates across every stage of their career.
Pension contributions do two things simultaneously: they build your retirement savings and they reduce your taxable profit in the year the contribution is made. That reduction in taxable profit means they cut your tax bill at exactly the same time as putting money aside for the future. This makes them one of the most effective planning tools available to a self-employed associate.
The NHS Pension Scheme
Associates carrying out NHS work are generally eligible to join the NHS Pension Scheme. It is a defined benefit scheme meaning your income in retirement is based on years of service and NHS earnings rather than on the performance of an investment fund. It also provides life assurance and ill-health retirement provisions. Contribution rates are tiered by earnings level. Check the NHSBSA website for current rates.
A SIPP or personal pension plan alongside the NHS pension gives both the security of defined benefits and ongoing tax planning flexibility. Private pension contributions receive relief at your marginal rate, which makes them particularly useful in high-earning years. Many associates use a combination: NHS pension for its long-term security, private pension for additional flexibility and ongoing tax management.
For example:
If you pay a lump sum into a private pension, part of it comes back to you automatically as basic-rate tax relief, added straight into the pension pot. If you pay tax at a higher or additional rate, you can claim further relief on top through your Self Assessment.
The end result is that the real cost to you of adding a given amount to your pension is usually noticeably less than the amount itself – often by a significant margin at higher tax rates. The exact saving depends on your tax rate and the relief rules in force at the time, so model your specific numbers with your accountant rather than relying on a fixed ratio.
Some private practices also auto-enrol associates into a workplace pension, particularly where the working arrangement is closer to employment than genuine self-employment. Whether this applies depends on your specific contract and working relationship with the practice – worth checking directly with the practice or your accountant if you’re unsure.
The pension annual allowance and Scheme Pays
There is an annual limit on how much you can contribute to pensions and still receive full tax relief. This is called the pension annual allowance. Exceeding it creates an additional tax charge. Check the current limit on the HMRC website.
The standard allowance can also be reduced for higher earners, tapering down based on your adjusted income – so the exact figure that applies to you depends on your total income, not just your pension contributions. Because the NHS Pension Scheme is defined benefit, what counts toward this limit is how much your pension’s value has grown in the year, not how much you’ve paid in.
A strong earning year or a pay rise can push that growth over the limit even if your actual contributions haven’t changed. Check the current allowance and taper thresholds on gov.uk, as both are reviewed periodically.
If your pension growth does exceed the annual allowance, the NHS Pension Scheme offers a “Scheme Pays” option – the scheme itself settles the tax charge on your behalf, in exchange for a corresponding reduction to your future pension. This avoids an unexpected lump sum tax bill in the year the charge arises.
Getting pension contributions right – NHS scheme, private pension, or a combination of both – takes more than a general understanding of the rules. Our payroll and pensions team handles the ongoing detail, from contribution tiers to annual allowance monitoring, so nothing gets missed as your income changes year to year.
Final checklist: are you on top of your tax as a dental associate?
Set aside a monthly percentage of income for tax from the first month of self-employment – your accountant can suggest a realistic figure.
Use accounting software to track income and expenses in real time and get a running estimate of your tax position.
Keep all receipts digitally – HMRC accepts scanned copies.
Review your position mid-year with your accountant so the January bill is not a surprise.
Confirm you’re registered for Self Assessment and know your filing and payment deadlines.
Have you budgeted for payments on account from the start, rather than being caught out by them?
Check your NHS income is being recorded and coded correctly, especially if you split time between NHS and private work.
Review your pension position this year, including whether your NHS pension growth is approaching the annual allowance.
If you genuinely cannot pay on time, contact HMRC before the deadline – Time to Pay arrangements allow installments.
Getting this right isn’t about knowing every rule yourself – it’s about having proper records and the right guidance behind you. Use this article as a starting point, then speak to a specialist who works with dental associates specifically, so nothing gets missed and nothing gets claimed without the paperwork to support it.
Dental Associate Taxes: FAQs
Do I need an accountant as a dental associate?
Not legally, but most associates find it worthwhile. A specialist dental accountant identifies expenses you may have missed, ensures your Self Assessment is correct, and helps you plan payments on account. The fee is itself a deductible business expense.
What if I work at multiple practices?
You report all income from all practices on a single Self Assessment return each year. Keep separate records for each practice so the return is accurate and you can track which expenses relate to which income.
Do I have to make payments on account?
Not always. You’re generally exempt if your previous year’s tax and Class 4 National Insurance bill was below a certain threshold, or if most of your tax was already collected at source. Check the current threshold on gov.uk, as it’s periodically reviewed.
What is a balancing payment?
Once your Self Assessment return is filed, HMRC works out your actual tax due for the year. If your payments on account didn’t cover the full amount, the shortfall is called a balancing payment, due on the same 31 January as your first payment on account for the following year.
Can I claim for working from home?
If you carry out administrative dental work from home such as updating patient records, correspondence, or CPD preparation, you may be able to claim a proportion of home costs. HMRC offers a simplified flat rate or you can calculate the actual proportion. Check current guidance on gov.uk.
What happens if I miss the Self Assessment deadline?
An automatic £100 penalty applies from the moment the 31 January deadline passes, regardless of whether you owe any tax. Further penalties accumulate at three months, six months, and twelve months. Interest applies on any unpaid tax from the due date. Contact HMRC as soon as possible if you think you will miss the deadline.
What happens if my NHS pension growth exceeds the annual allowance?
You may face an annual allowance tax charge based on how much your pension has grown that year, not how much you’ve contributed. The NHS Pension Scheme offers a “Scheme Pays” option, where the scheme itself settles the charge in exchange for a reduction to your future pension, avoiding an unexpected lump sum bill.
Can I opt out of the NHS Pension Scheme?
Yes. Associates can opt out, though doing so means giving up defined benefit accrual on NHS earnings. Some higher earners opt out specifically to manage annual allowance charges. The implications are significant and worth discussing with a financial adviser who understands the NHS pension before making any decision.
Can I join a workplace pension as a dental associate?
Some private practices auto-enrol associates into a workplace pension, particularly where the working relationship is closer to employment than genuine self-employment. Whether this applies depends on your specific contract – worth checking directly with the practice or your accountant.

The structure you operate through shapes almost everything about how your practice is taxed, how much personal risk you carry, and how clean an eventual sale or handover would be. Most dentists end up in the wrong structure for their income level not through bad decision-making but simply because they started somewhere sensible and never revisited it.
This article covers the four main options, when each makes sense, and what you need to know before making any change. For the full picture across tax, payroll and compliance, see the complete guide to dental accounting and tax.
What this article covers
How sole trader, partnership, LLP, and limited company actually work for a UK dentist
The company director rule under the Dentist Act 1984 that catches out practices using a generalist accountant
What genuinely changes when you incorporate, and what doesn’t
How incorporating can affect your NHS contract and pension arrangements
Key Takeaways
Sole trader, partnership, LLP, and limited company are the options – incorporation is the move between them, not a separate structure.
Most dental companies with a non-dentist co-director breach the Dentist Act 1984 – a common error, up to £5,000 fine.
Incorporating can trigger an NHS contract review, so involve a lawyer before assuming the tax saving is worth it.
Limited companies tend to pay off once profits consistently attract higher-rate Income Tax – check current rates before deciding.
Review your structure every 2-3 years, and always before a sale, a partner change, or a big income jump.
Sole trader: the starting point for most dentists
How it works
No legal separation between you and your business. You register for Self Assessment with HMRC, keep records of income and expenses, and submit a tax return each year. Minimal paperwork involved and you can begin trading almost immediately after registering.
You pay Income Tax and National Insurance on your profits, not on your total income. Deducting legitimate business expenses from your earnings reduces the profit figure that tax is calculated on. For current Income Tax and National Insurance rates, check the HMRC website directly. These change with each Budget.
Unlimited personal liability. If the business faces financial difficulties, a legal claim, or a compliance problem, your personal assets are at risk. That includes your home and savings. This is manageable when you are starting out as an associate with modest assets. It becomes a real concern as the practice and your financial exposure grow.
Sole Trader at a Glance
Pros
Cons
Quick and inexpensive to set up
Unlimited personal liability
Simple tax reporting through Self Assessment
Higher tax rates as profits grow
Full control over income and decisions
Harder to secure external funding
Low admin and accounting costs
May appear less professional to lenders or buyers
Best suited to: new associates and part-time practitioners wanting a simple starting point. Worth reviewing once income grows significantly or once you start taking on staff.
Partnership: sharing ownership and its consequences
How it works
Two or more dentists running a practice together. The partnership itself does not pay tax. Each partner declares their share of profits on their own Self Assessment return and pays Income Tax and National Insurance accordingly. A Partnership Tax Return goes to HMRC separately each year.
The joint liability problem
Every partner is personally responsible for the debts and obligations of the whole partnership, not just their own share. If one partner makes a costly mistake or faces a legal claim, all partners are potentially exposed. For dental practices involving expensive equipment, regulatory obligations, and patient complaints, that shared exposure is worth taking seriously.
The LLP alternative
Some dental teams choose a Limited Liability Partnership instead of a standard partnership. An LLP gives each partner limited personal liability for the actions of the other partners, while the tax treatment stays similar to a partnership. The compliance requirements are higher than for a standard partnership but the liability protection can make it worthwhile where the shared exposure concern is material.
The partnership agreement is not optional
Whether you form a standard partnership or an LLP, a written agreement is essential. It needs to cover how profits and losses are shared, each partner’s responsibilities, what happens if someone wants to leave or cannot work, and how disputes are resolved. Without one, UK partnership law applies default rules that almost certainly do not reflect what the partners actually agreed or intended.

Limited company: protection and tax efficiency
What changes
A limited company is a separate legal entity. It can own assets, enter contracts, and pay tax in its own name. Your personal finances are generally protected from business debts and claims. As a dentist running a limited company, you are typically both director and shareholder, which lets you take income as a combination of salary and dividends. That combination is usually more tax-efficient than being taxed entirely as self-employed, particularly once profits reach the point where higher-rate Income Tax consistently applies.
The dental-specific rule most people miss
Here is something a generalist accountant frequently gets wrong when setting up a limited company for a dental practice. Arun Mehra, CEO of Samera, raised this directly in a client meeting the morning this article was being written:
“Time and time again, we see people where they’ve set up a company with a generalist accountant and one director is a dentist and one director is not. That is actually wrong. You cannot do that under the Dentist Act 1984. The majority of the directors have to be on the GDC register, effectively a dentist, dental nurse, or hygienist. And there are many, many companies out there trading with a spouse who’s a dentist and another spouse who’s not. The GDC can fine you up to £5,000 just for that little error.”
Arun Mehra Samera Founder & CEO
How the tax works
The company pays Corporation Tax on its profits. You then pay tax on what you take out, whether as salary through PAYE or as dividends. The combined tax burden is typically lower than paying higher-rate Income Tax as a sole trader. From April 2026, dividend tax rates are scheduled to increase, which changes the salary-versus-dividend calculation. Review this annually with your accountant rather than setting it once and leaving it.
Salary versus dividends, Corporation Tax, Section 455, the numbers shift every time the rules change. We review this with you every year, not just at incorporation.
More administration than a sole trader setup. Annual accounts filed at Companies House. A Corporation Tax return each year. A confirmation statement. Directors have legal duties under the Companies Act 2006, filing accurately, paying tax on time, keeping proper records, acting in the company’s interests. Accounting costs are higher, but for established practices with meaningful profits the tax savings typically outweigh them.
Limited Company at a Glance
Pros
Cons

A worked tax example (illustrative only – always check current rates)
Say your practice makes £100,000 profit in a year. As a sole trader, that profit is taxed entirely through Income Tax and National Insurance. As a limited company, the same profit is split between Corporation Tax on what the company keeps, and dividend or salary tax on what you draw out personally – typically landing at a lower combined figure once profits reach this level.
The exact gap depends on the tax year, your salary/dividend split, and your personal circumstances – it can be several thousand pounds either way, and it narrows as dividend tax rates rise. This example is illustrative only, based on current bands at the time of writing. Model your own numbers with a specialist accountant before deciding – don’t rely on a figure from an article that may be a tax year or two old by the time you read it.
For current Income Tax, Corporation Tax, NI, and dividend tax rates, check the HMRC website directly. These change with each Budget and figures in articles can go out of date.
“I had a call with a client literally this very morning. They hadn’t structured it right. They had a holding company above their existing company and then got a loan in their personal name, which they loaned to the dental clinic. That had a knock-on effect when they had to refinance, they ended up suffering something called Section 455 tax, which was completely unexpected. It created quite a big cash flow issue. That is a common problem and it always comes from the structure not being set up correctly from the start.”
Arun Mehra Samera Founder & CEO
Incorporating an existing practice
What it involves
Incorporation converts an existing sole trader or partnership into a limited company. All business assets transfer to the company. HMRC treats this as a disposal, which can trigger Capital Gains Tax on any increase in value. Incorporation Relief under Section 162 of the Taxation of Chargeable Gains Act 1992 can defer this CGT until shares are eventually sold, provided qualifying conditions are met.
Goodwill needs a proper valuation, not a guess
Goodwill – your practice’s patient list, reputation, and brand value – transfers to the company as part of incorporation, and it has to be valued correctly. Undervalue it and you risk missing legitimate relief; overvalue it and you risk an inflated CGT bill or an HMRC challenge. This is specialist territory – a dental accountant familiar with HMRC’s approach to goodwill in dental practices should handle the valuation, not a generalist.
Getting goodwill wrong either way costs you, missed relief on one side, an inflated tax bill or an HMRC challenge on the other. We value it properly, using HMRC’s own approach to dental goodwill.
Natasha Gnanapragasam, Director of Operations, Accountancy and Tax at Samera, on why the decision cannot be made casually:
“Incorporation is a big decision. Before, it was more straightforward because the tax savings were clearer. But now the rules have changed, taxes have increased, everything has shifted. So what we do is highly recommend that associate dentists, before they incorporate, do a proper incorporation assessment. So they know exactly what they’re going to face afterwards. No surprises. Because some of them just come to us and say ‘I want to incorporate’ without realising what’s going to happen once they do. The assessment puts them in a much better position.”
Natasha Gnanapragasam Director of Operations
When to think about incorporating
Profits are consistently attracting higher-rate Income Tax as a sole trader.
Personal asset protection has become genuinely important as the practice takes on more risk.
You are planning to expand, hire more staff, or open additional locations.
NHS contracts and what dentists typically do not know
This is the part of incorporation that gets overlooked most often. Arun on what NHS dental clients typically do not know when this question comes up:
“The big thing they don’t know is that incorporating could potentially lead to them having to renegotiate the contract value with the local area team, because it could be seen as a fundamental change to the contract. This is why we always say get a lawyer involved early in the process, because they’ll understand the contract implications. Tax-wise it might be better to incorporate. But if they lose the contract or it gets renegotiated, it may not be worth doing it at all. That’s what they typically don’t know going in.”
Need Professional Help Choosing the Right Business Structure?
Choosing whether to remain a sole trader, start a partnership, or turn your dental practice into a limited company is a big step. It’s not just about paperwork, it affects your taxes, profits, and how your business can grow in the future.
At Samera, we work closely with dentists to help them set up the most suitable business structure, safeguard their assets, and plan confidently for what lies ahead.
Our team of dental accounting specialists understands the specific tax rules, NHS contract details, and compliance challenges that dental professionals face. Whether you’re opening your first clinic or expanding an existing one, we’ll explain your options clearly and guide you towards the structure that suits your goals and circumstances.
Getting the structure wrong – especially with an NHS contract in place – can cost more than it saves. We handle the ongoing compliance and company management that comes after incorporation.
When should a dentist switch to a limited company?
When the tax savings consistently outweigh the additional accounting and compliance costs, which typically happens once profits are high enough to attract higher-rate Income Tax on a sustained basis. The exact tipping point depends on your income, expenses, and circumstances. A specialist accountant can model the difference for your specific situation.
Does changing my business structure affect my NHS contract?
Yes. You must notify NHS England when you change structure. Your provider number and pension arrangements may need updating. Incorporation could be treated as a fundamental change to the NHS contract, which is why getting a lawyer involved early is important, not optional.
What is the GDC director rule for dental companies?
Under the Dentist Act 1984, the majority of directors of a dental company must be on the GDC register, which means they must be a dentist, dental nurse, or hygienist. Setting up a company with a non-dental co-director is a common error when using a generalist accountant. The GDC can fine the company up to £5,000 for this.
What is Incorporation Relief?
Incorporation Relief defers Capital Gains Tax when you transfer a business into a limited company. The gain is held over until you eventually sell your shares rather than being triggered at the point of transfer. Specific qualifying conditions apply, which your accountant can confirm.
Do I need a partnership agreement?
Not legally. But without one, UK partnership law applies default rules about profit sharing, decision-making, and partner exits that almost certainly do not match what the partners actually intended. Not having an agreement is a risk that grows as the partnership’s assets and complexity increase.
What’s the difference between a partnership and an LLP?
A standard partnership means every partner is personally liable for the whole business’s debts, including mistakes made by other partners. An LLP gives each partner limited liability for the others’ actions, while the tax treatment stays broadly similar to a partnership. The trade-off is higher compliance costs than a standard partnership.
What is Section 455 tax and how do dentists get caught out by it?
Section 455 is a Corporation Tax charge that applies when a director borrows money from their own company and the loan isn’t repaid correctly. It typically catches people out when a company structure – such as a holding company with a personal loan sitting behind it – hasn’t been set up properly from the start, and the charge often arrives unexpectedly during a refinance.
How is goodwill valued when I incorporate my practice?
Goodwill – your patient list, reputation, and brand value – needs a proper valuation by a dental accountant familiar with HMRC’s approach to goodwill specifically. Undervaluing it risks missing legitimate relief; overvaluing it risks an inflated Capital Gains Tax bill or an HMRC challenge.
Do I need to re-register for VAT or payroll when I incorporate?
Yes, if your previous business was VAT-registered, you’ll need to re-register under the new company name. Payroll (PAYE) also needs to be transferred or re-registered under the company before running your first payslip through it.

Payroll and pension compliance are two of the highest-risk operational areas for dental practices. When they run correctly, they are largely invisible. When they go wrong, the consequences range from automatic HMRC penalties through to formal investigations. In the case of NHS pension errors, the financial problems for staff only surface years later when they approach retirement.
This article covers what practice owners, principals, and managers need to understand about PAYE, RTI, NHS pensions, auto-enrolment, and IR35.
PAYE and RTI: what the practice must do every time it pays staff.
NHS pension obligations for both employed staff and self-employed associates.
Auto-enrolment: the workplace pension obligation every employer carries.
IR35 and employment status for dental associates, including what changed in April 2023.
Year-end payroll obligations and the deadlines that actually matter.
Key Takeaways
PAYE and RTI are per-payday obligations, not monthly admin – a Full Payment Submission is due on or before every payday, and late submissions are one of the most common sources of payroll penalties in dental practices.
HMRC withdrew the concession treating dental associates as self-employed by default in April 2023 – every associate’s status now needs assessing on its own facts, with hygienists and therapists at particular risk.
If HMRC reclassifies an associate as employed, the practice carries the liability for backdated PAYE and employer National Insurance, not the individual – a real exposure even for practices that run RTI perfectly for their employed staff.
The NHS Pension Scheme and workplace auto-enrolment are entirely separate obligations, calculated differently, and staff doing NHS work may need managing under both at once.
Auto-enrolment re-enrolment is required every three years and is the requirement most commonly missed simply because nothing prompts it – worth a standing reminder rather than relying on memory.
Why payroll is high-risk in dental practices
Most businesses employ either employees or self-employed contractors. Dental practices typically run both at the same time: dental nurses, receptionists, and practice managers on PAYE alongside self-employed associates. The NHS pension applies to a subset of each group under completely different rules. And the question of whether associates are genuinely self-employed is one HMRC examines closely in the dental sector specifically.
HMRC, the Pensions Regulator, and the NHS Business Services Authority all monitor dental practices for payroll and pension compliance. Errors are not treated leniently even when clearly unintentional, which is why getting the foundations right matters more than catching up later.
Gross pay and net pay
Gross pay is what an employee earns before any deductions. Net pay is what actually lands in their bank account, after Income Tax, National Insurance, and anything else – pension contributions, student loan repayments – has been taken off. Payslips need to show both clearly, along with each deduction, so staff can see exactly how one figure becomes the other.
PAYE: what the practice must do
If your practice employs staff, you must operate PAYE. The practice deducts Income Tax and employee National Insurance from wages before they are paid, calculates employer NI on top, and passes both to HMRC by the relevant monthly deadline.
Where things commonly go wrong
Wrong tax codes applied because starter checklists were not completed when new staff joined.
Not registering as an employer before taking on the first member of staff.
Treating workers as self-employed when the working arrangement clearly points to employment.
Late PAYE and NI payments, which attract automatic interest charges from HMRC.
Getting PAYE, RTI, and auto-enrolment right every payday takes more than good intentions – it takes a system that doesn’t rely on remembering. Our payroll and pensions service handles this for practices so nothing gets missed on a monthly deadline.
Under Real Time Information, a Full Payment Submission must be sent to HMRC on or before every single payday. Not at month-end. On or before the date staff are paid. Late or missing RTI submissions are one of the most common sources of payroll penalties in dental practices. The reason is almost always the same: the practice treated it as a monthly admin task rather than a per-payday obligation. Set up payroll software to submit automatically on each pay date.
P60s must be issued to every employee still on payroll by 31 May. Used by staff for mortgage applications, tax refund claims, and personal returns. Late issuance creates complaints and HMRC attention.
P11Ds reporting taxable benefits in kind must go to HMRC by 6 July.
Class 1A NI on benefits is due by 19 July, or 22 July for electronic payment.
HMRC is moving towards compulsory payrolling of benefits in kind from April 2027, meaning most benefits will need to be reported through payroll in real time rather than on annual P11D forms. Start reviewing how you currently manage employee benefits to prepare.
HMRC’s move toward compulsory payrolling of benefits from April 2027 is part of a broader shift toward real-time digital reporting. Find out what’s already required now and what’s coming next for your practice.
Every UK employer must comply with workplace pension auto-enrolment. For dental practices this means assessing all workers, automatically enrolling eligible ones, making minimum employer pension contributions, and re-enrolling every three years. The re-enrolment requirement is the one most commonly missed because it is easy to forget without a specific system. Minimum contribution rates are set by the Pensions Regulator. Check their website for the current requirements.
The NHS Pension Scheme is entirely separate from workplace auto-enrolment and significantly more complex. It applies to income earned from NHS-contracted work and is administered by the NHS Business Services Authority. This is the area where errors most quietly accumulate and most expensively resolve.
For employed dental staff
Employed staff working under NHS contracts must be enrolled in the NHS Pension Scheme. The practice deducts employee contributions, pays the required employer contributions, and submits accurate pensionable pay details to the NHSBSA. Contribution rates are tiered by earnings level. Check the NHSBSA website for current rates.
Self-employed associates carrying out NHS work can join the NHS Pension Scheme. Their pensionable pay is calculated based on net NHS earnings using a formula that differs from how a salary is pensioned. Associates declare pensionable earnings annually and practices have parallel reporting obligations to confirm the figures.
Because associate income mixes NHS and private work in proportions that vary year to year, calculating the correct NHS pensionable pay is technically demanding. Errors made now typically surface only when associates approach retirement, at which point they can be very difficult or impossible to correct. This is an area where specialist input is genuinely necessary rather than simply helpful.
This complexity multiplies across a multi-site group, see our guide to taxes for dental groups for how structure and succession planning interact with staff obligations at scale.
NHS pensionable pay for associates mixes NHS and private income in proportions that shift year to year, and errors here often don’t surface until someone’s approaching retirement. Our practice owner accounts service includes the specialist input this calculation genuinely requires.
IR35 and employment status: what changed in April 2023
Charles Suthakran, Business Development Executive, Accountancy and Tax at Samera, explains the specific change that made employment status assessment more important for dental practices than it has ever been:
“For years, there was a specific HMRC concession that effectively treated associate dentists as self-employed by default. That was withdrawn in April 2023. Since then, every associate’s status is meant to be assessed on its own facts, the same as any other sector, using HMRC’s status tool. And the people most at risk of being on the wrong side of it are usually hygienists and therapists, where the day-to-day arrangement can look a lot more like employment.”
Charles Suthakran Dental Accountant
Charles on where the liability lands when HMRC decides a clinician should have been on payroll:
“If HMRC decides someone you’ve been paying gross should have been on the payroll, it’s the practice, as the employer, that’s on the hook for the PAYE and the employer’s National Insurance, which is now 15%, plus penalties. Not the individual. So you can have a practice that runs RTI perfectly for its nurses and receptionists and still be carrying a significant exposure, because the real risk is sitting with the people who were left off payroll entirely on an assumption that no longer holds.”
Charles Suthakran Dental Accountant
The fix is straightforward. Charles:
“Run a proper status assessment for each clinician, keep the result on file, and make sure the working arrangement matches the contract. That’s it.”
HMRC assesses employment status using three factors: control (how much the practice directs how and when work is done), substitution (whether the associate can genuinely send someone else), and mutuality of obligation (whether there is an ongoing obligation to offer and accept work). A contract that says self-employed provides no protection if the practical working arrangement looks like employment.
Getting this right often connects to a wider structural decision, see our guide to choosing the right business structure for how employment status interacts with it.
Getting associate status right is a structural decision, not just a payroll formality – it affects tax treatment, National Insurance exposure, and how the whole arrangement holds up if HMRC ever looks closely. Our tax planning team works through this with practices proactively, not after a status assessment has already gone wrong.
Associates treated as self-employed without proper status assessment. Use HMRC’s CEST tool for each clinician independently. Do not apply the same assumption to everyone.
Missing auto-enrolment re-enrolment. Must happen every three years. Set a calendar reminder well in advance.
NHS pension calculations done incorrectly. Errors go unnoticed for years and surface when someone is approaching retirement. Check regularly.
RTI submissions sent after the pay date. Set payroll software to submit automatically on or before each pay date, not as a monthly batch.
P60s not issued by 31 May. Hard deadline. Late issuance creates staff complaints and HMRC risk.
The foundations matter more than the fixes
Every area covered here – PAYE, RTI, auto-enrolment, the NHS Pension Scheme, and employment status – shares the same underlying pattern: these obligations are largely invisible when handled correctly, and expensive when they aren’t. The April 2023 change to associate employment status is a good example of why this needs ongoing attention rather than a one-off setup. What was safe practice a few years ago can quietly become a live exposure once the rules move, and nobody notices until HMRC does.
None of this requires becoming a payroll expert yourself. It requires knowing which areas carry real risk, running the right checks – a status assessment for every clinician, a calendar reminder for re-enrolment, payroll software set to submit on or before each payday – and getting specialist input where the technical detail genuinely warrants it, particularly around NHS pension calculations for associates. Use this article as your starting point, then speak to a specialist who understands the specific compliance risks dental practices carry, so nothing gets missed and nothing gets left as an assumption that no longer holds.
Payroll, NHS pensions, and employment status all sit alongside the wider financial picture of running a dental practice – none of it works in isolation. Find out how we support practices across all of it, from the accounts up.
Did the rules about dental associate employment status change recently?
Yes. HMRC withdrew a specific concession in April 2023 that had effectively treated dental associates as self-employed by default. Since then, every associate’s status must be assessed on its own facts using the same criteria as any other sector. Hygienists and therapists are particularly at risk because their day-to-day working arrangements can look more like employment.
Who is liable if HMRC decides an associate should have been on payroll?
The practice, as the employer, is liable for the unpaid PAYE and employer National Insurance, not the individual associate. Employer NI is currently 15%. Penalties also apply to the practice.
What are the main payroll deadlines for dental practices?
RTI Full Payment Submissions must be sent on or before every payday. PAYE payments are due to HMRC by the 22nd of the following month for electronic payment. P60s must be issued to employees by 31 May. P11Ds must be submitted by 6 July. Class 1A NI is due by 19 July.
What is the difference between NHS Pension and workplace auto-enrolment?
NHS Pension is a defined benefit scheme for NHS earnings, administered by the NHSBSA. Workplace auto-enrolment is a separate legal obligation for all employers, providing a defined contribution pension scheme based on total earnings. Staff doing NHS work may need to be managed under both schemes simultaneously. They serve different purposes and are calculated using entirely different methods.
Can I outsource payroll management for my dental practice?
Yes, and for many practices this is the right decision. A specialist dental payroll provider understands NHS pension requirements, the employment status risks specific to dental associates, and IR35 considerations. Outsourcing reduces error risk and frees up administrative time for clinical and practice management work.
What’s the difference between an employee and a worker?
Employee and worker are distinct legal statuses. Workers have some employment rights – such as the National Minimum Wage and paid holiday – but not the full set that employees get, including protection from unfair dismissal. The distinction matters for how you manage and pay someone, separately from the self-employed versus employed question covered under IR35.
How often should we pay staff – monthly or more frequently?
Most dental practices pay monthly, which aligns naturally with typical NHS and private income cycles. Whatever frequency you choose, RTI reporting obligations are the same – a submission is still due on or before every payday, regardless of how often that is.
Do we need to make deductions for court orders?
Yes, if HMRC or a court instructs you to. An attachment of earnings order requires the practice to deduct a specified amount from an employee’s pay, alongside the usual Income Tax, National Insurance, and any other deductions. These instructions come directly from the relevant authority and must be applied as specified.

Over the last 20 years, we have seen many dental groups emerge across all parts of the world. Some very large, others smaller, but often seeking to be acquired by the larger groups at some stage, or even the vague hope of an IPO (Initial Public Offering).
The basic premise has always been to buy a dental practice or office at a certain price multiple of EBITDA , add a few more, or a few hundred more, and then sell the whole group at a much higher multiple (with a much bigger EBITDA) than what the individual practices have been acquired for.
Sounds simple – what could go wrong?
Well in a rising market, buyers and group owners who timed their exits rightly have done well financially.
But what about the many hundreds or even thousands of dental groups across the globe that still are operating, but the arbitrage exit opportunity they were hoping for has not manifested?
In the UK in this current high-interest rate environment things look very different for many dental groups.
When rates were low, borrowing was cheap, which aided the growth strategies of many of these groups, yet today, whilst some groups are buying, the appetite to purchase a practice has drastically diminished from not only the smaller groups but also PE-backed ventures too.
Along with the aforementioned higher interest rates, the cost-of-living crisis, and a difficulty in recruitment, have also contributed to the slowdown in many dental groups.
The lack of available manpower has contributed to many NHS-funded dental groups, returning funds to the Department of Health unable to meet their UDA targets.
According to the FT, NHS Dental clawback was around £150million in 2022-23. I expect it won’t be very pretty this year either, from the groups I have been talking to.
Whilst some private dental groups, have struggled to grow the top line as quickly as they had hoped, again due to manpower issues, increased competition and a lack of personnel.
In the good times, its relatively straightforward to make money building a dental group, but in my view it will be the groups that really get to grips with their financials that will emerge strongest in the down times.
With my wealth of experience over the last 20 years working with a whole host of groups, these are my 6 tips to build a finance and accounting function that will actually grow your EBITDA, but also ensure you achieve the price multiple you desire upon exit.
Tip 1: Have you got a Systems Based Mindset?
The backbone of anything successful organisation are its systems – with the financial and accounting function paramount to success. Unfortunately, I have seen this as a major afterthought by many dental group or DSO owners, seeing it as an overhead rather than something that could help them grow a successful empire.
The first step really is about changing your mindset, and thinking about what data and information do you need to have available at your fingertips to make better decisions.
As it will be interpreting the data to ensure high quality decisions that will determine the success of your group.
You will need robust systems for everything from HR to marketing to compliance to accounting.
I personally like to call it a Systems Based Mindset. So, If you have this, you are on the right track.
Now in the context of finance and accounting, you need to have a solid framework and system in place.
If you don’t, that’s your first starting point. So ask yourself what financial data do you need to know to make good decisions? Examples could include:
Profitability by location
Profitability by Associate Dentist
Hourly rate of each Associate Dentist
Key Overheads as a % of Turnover
Cost of acquiring a new patient
EBITDA to interest coverage ratio
The list is endless, but the above are a good starting point.
The framework will depend on your business structure and how you organised your group but the key factor here is you must be able to see the performance of each of your practices in your group.
There really is no excuse to not be able to see which sites are doing great and which ones aren’t.
They may all be under one company, but it really is essential to have the financial visibility of each site. If you don’t have this, you are at a significant disadvantage when it comes to making quality decisions.
Remember, quality business decisions can only occur when you have visibility of performance. If it’s all jumbled together, you will only get so far, and you won’t be able to develop your group further until you have clarity of performance.
Once you know you need to have financial performance information for each site, then there are numerous accounting systems available to really help you gather the information and automate much of this process.
But the key has to be implementing this correctly. You will need to consider the following:
How to get invoice and income information into the system?
Will it be with an automated OCR system?
Which bookkeeping system is most suitable?
What about standardised charts of accounts?
Will all information be centralised, or will each practice have to send the information separately?
What about purchasing and payment authorities? Do you have controls in place?
Have you a hierarchy in place for this for sign offs?
What about automating much of the accounts payable side of things to speed up payments to suppliers and make your group much more efficient?
More questions than answers, but this process of evaluating the right technology and software is paramount to ensure an efficient finance and accounting function for your dental group.
Tip 4: Choosing the right accounting tech stack for your group.
The world of accounting software has exploded in the last decade.
Of course, the software should be cloud-based, but apart from that you will need professional help to determine the right accounting technology stack for your dental group.
In terms of bookkeeping software, there are well-known products such as Xero, Quickbooks, Sage just to name a few.
But then there is the range of additional apps that could help you streamline and speed up the whole data capture side of things, these include Dext, hubdoc, Approvalmax, Lightyear.
Then when it comes to accounts payable you will want software that will integrate into your chosen bookkeeping software. Software such as Telleroo, Crezco, Payhawk are examples here.
Then for reporting purposes, you may want to consider Spotlight, Syft or Joinn.
The right tech stack can only be implemented once a full understanding of the workflow within your accounting function has been determined.
Tip 5: What About Your Accounting Team?
Time and time again, I have seen inexperienced non-accounting team members get involved in probably one of the most important parts of the group – the money.
Why have a practice manager perform the bookkeeping, when a bookkeeper could do this efficiently and properly?
Garbage in means, garbage out, it is essential to have accurate data entry in a standardised manner, or else any reports you rely on will be inaccurate and lead to poor decision-making.
Therefore, having the right people doing the right job is a pre-requisite here.
The larger the dental group the larger the team will be, which will include bookkeepers and accountants.
You can hire internally for these roles, or alternatively outsource this to firms like ours that have the experienced manpower to support your group.
The bookkeeping should be done daily, with the management accounts available at the end of each month, and a review of each practice’s performance should be evaluated – that’s when you know if things are going to plan.
Without a regular review of performance, assuming you have followed steps 1 to 5 above, it would have been a pointless exercise.
Therefore, make sure you review the performance of each site and then take any necessary action swiftly.
The numbers always tell the story, but your whole finance and accounting function must been structured and enabled to tell you the full story, not a half-baked cobbled-together story of your dental group’s performance.
If you are a Dental Group or DSO anywhere across the world, with our shared service centre with talented team members, we can help you implement and run a much more efficient accounting and finance function but also help you grow a better dental group or DSO.
As that’s the ultimate aim, to build a quality dental group that creates value for all stakeholders.
Good luck, and get in touch if you need assistance.
How should I set up accounting systems for a dental group?
To set up accounting systems for a dental group, start by choosing robust accounting software that can handle multiple locations and centralize financial data. Implement standardized processes across all practices for tracking income, expenses, and payroll. Set up a unified chart of accounts to maintain consistency in financial reporting. Ensure regular financial reviews and reconciliations to monitor performance and cash flow. Finally, train staff on the accounting procedures to ensure accuracy and compliance.
What are the best practices for managing cash flow across multiple practices?
To manage cash flow across multiple dental practices, maintain a centralized cash flow management system to monitor income and expenses. Implement standardized invoicing and payment processes to ensure timely billing and collection. Regularly review cash flow statements to identify trends and address issues quickly. Use budgeting and forecasting tools to plan for future cash needs and allocate resources efficiently. Keep reserves for unexpected expenses and consider inter-practice loans to balance cash flow between locations.
How do I ensure compliance with tax regulations for a dental group?
To ensure compliance with tax regulations for a dental group, centralize your accounting to track all income, expenses, and payroll accurately. Regularly review tax obligations for each practice, including VAT, corporation tax, and PAYE, and ensure timely submissions to HMRC. Implement standardized processes across all locations and work with a tax advisor familiar with dental practices to stay updated on regulatory changes. Conduct regular audits to identify and correct any discrepancies.
What accounting software is recommended for dental groups?
For dental groups, recommended accounting software includes options like Xero, QuickBooks, and Sage. These platforms offer features tailored for multi-practice management, such as centralized financial tracking, payroll integration, and real-time reporting. They also provide scalability to accommodate the growth of your dental group and ensure compliance with tax regulations. It’s important to choose software that integrates well with other tools you use and provides robust support for managing multiple locations.
How can I streamline payroll for multiple dental practices?
To streamline payroll for multiple dental practices, use centralized payroll software that handles multi-location payroll processing efficiently. Automate calculations for salaries, taxes, and benefits across all practices, ensuring consistency. Set up a unified system for employee records and time tracking to simplify payroll management. Regularly review and update payroll data to ensure accuracy and compliance with tax regulations. Outsourcing payroll management to a specialized provider can also reduce administrative burden and ensure efficiency.
What financial reports are essential for managing a dental group?
Essential financial reports for managing a dental group include:
Profit and Loss Statement: Tracks income and expenses, showing overall profitability.
Cash Flow Statement: Monitors cash inflows and outflows, ensuring liquidity.
Balance Sheet: Displays the group’s assets, liabilities, and equity.
Budget vs. Actual Report: Compares projected budgets with actual financial performance.
Payroll Report: Details employee compensation, including taxes and benefits.
These reports are critical for making informed financial decisions and maintaining the financial health of the dental group.
How do I handle inter-practice billing and expenses?
To handle inter-practice billing and expenses within a dental group, establish a centralized system to track and allocate costs accurately across all practices. Use accounting software to automate the allocation of shared expenses, such as marketing or administrative costs, to ensure each practice bears its fair share. Implement clear policies for inter-practice billing, detailing how expenses will be tracked, billed, and reconciled. Regularly review these processes to maintain transparency and ensure accuracy.
What are the key considerations for budgeting in a dental group?
Key considerations for budgeting in a dental group include:
Revenue Projections: Estimate income for each practice based on patient volume and services offered.
Expense Management: Track fixed and variable costs, including salaries, rent, and supplies.
Cash Flow Planning: Ensure liquidity to cover operational costs and unforeseen expenses.
Capital Expenditures: Plan for investments in new equipment or technology.
Profit Margins: Monitor profitability across all practices to maintain financial health.
How often should I review financial performance across practices?
You should review financial performance across practices on a monthly basis. Regular monthly reviews help you monitor key metrics like revenue, expenses, and profitability, allowing you to address issues promptly and adjust strategies as needed. Quarterly reviews can provide a broader perspective on trends, while annual reviews are essential for strategic planning and setting long-term goals. Consistent monitoring ensures that each practice remains financially healthy and contributes positively to the overall group.
How do I manage debt and credit within a dental group?
To manage debt and credit within a dental group, first, establish clear policies for borrowing and repayment to maintain healthy cash flow. Regularly review debt levels across practices and prioritize paying off high-interest debt to reduce financial strain. Use credit responsibly to finance essential investments, and monitor credit terms closely to avoid penalties. Maintain a strong relationship with lenders and ensure that all practices contribute to meeting debt obligations.
What role does inventory management play in accounting for a dental group?
Inventory management plays a crucial role in accounting for a dental group by ensuring accurate tracking of supplies and materials across practices. Effective inventory management helps control costs, reduce waste, and maintain optimal stock levels, which directly impacts cash flow and profitability. It also supports accurate financial reporting by aligning inventory levels with expenses, ensuring that supplies are accounted for in the right periods. Implementing inventory management software can streamline this process and improve overall financial efficiency.
How can I optimize tax planning for a dental group?
To optimize tax planning for a dental group, consider consolidating expenses and leveraging tax-efficient structures like group relief to offset profits and losses across practices. Utilize capital allowances for equipment and property investments, and ensure that you maximize allowable deductions and credits. Strategic timing of income and expenses, along with regular reviews of tax liabilities, can help reduce the overall tax burden. Consulting with a tax advisor who specializes in dental practices can provide tailored strategies for your group.
What are the benefits of centralized vs. decentralized accounting?
Centralized Accounting:
Offers consistency and control by consolidating financial data from all practices in one place.
Enhances efficiency through standardized processes and reporting.
Facilitates easier compliance with regulations.
Decentralized Accounting:
Allows individual practices to maintain control over their financial operations.
Can be more responsive to the specific needs of each practice.
May lead to inconsistencies and require more oversight to ensure accuracy and compliance across the group.
How do I track profitability for each practice in a dental group?
o track profitability for each practice in a dental group:
Use Individual Profit and Loss Statements: Generate P&L statements for each practice to monitor revenue, expenses, and net income.
Allocate Shared Costs: Distribute shared expenses, like marketing or administrative costs, proportionally.
Monitor Key Metrics: Track metrics such as patient revenue, cost per patient, and operating margins.
Use Accounting Software: Implement software that supports multi-practice financial tracking.
Regularly review these reports to assess performance and make informed decisions.
What challenges might I face in managing the accounts of a growing dental group?
Managing the accounts of a growing dental group can present several challenges:
Complexity: Increased financial transactions and inter-practice billing can complicate accounting.
Consistency: Ensuring standardized financial processes across multiple practices is difficult.
Compliance: Keeping up with tax regulations and legal requirements across all practices can be challenging.
Cash Flow Management: Balancing cash flow between practices and funding growth without overextending resources is essential.
Scalability: Accounting systems may need upgrades to handle the expanded operations effectively.
I have a small dental group of just 2 sites, does the methodology outlined apply here too?
Yes.
In our experience, having a well-thought-through workflow which is expandable is key to success. Get this structure right, and you then have a solid platform for your 2 sites, and any additional sites you acquire or start up.
This sounds complex, can Samera help my dental group?
Simply yes. We can help you with the whole set up and running of the accounting and finance operation of your dental group, or just one aspect, including providing experienced team members to carry out all aspects of the work required.
What’s the first step in setting this all up?
In our experience, the key is to understand your existing processes and workflows, and then define a detailed workflow for your organisation. Our advice would be to implement this stage by stage, rather than all at once.
How much experience does team Samera have in this area?
We have been working with Dental groups and DSO’s for over twenty years, so we have seen most things, and also through our sister business, The Neem Tree Dental Group, we test all our processes, to ensure they are robust before sharing with our dental group clients.
Does team Samera work with international Dental Group clients?

Most dentists are not particularly interested in bookkeeping. Completely understandable. But the practices that run most smoothly, the ones where the January tax bill is not a nasty shock and the accountant is not spending months chasing receipts are nearly always the ones where someone has been keeping reasonably tidy records all year.
This article explains what bookkeeping involves for a dental practice specifically, which records matter and why, what the financial reports are actually telling you, and which software most practices use. The aim is to make the subject less mysterious, not to turn you into a bookkeeper.
What bookkeeping actually involves for a dental practice and why it is more complex than for most businesses.
The three financial statements every practice owner should be able to read: P&L, balance sheet, cash flow.
How to set up a system that does not fall apart at year-end.
Which software most dental practices in the UK actually use and why.
Key Takeaways
Bookkeeping is the recording; accounting is what your accountant does with those records – messy books mean higher fees and slower work.
Dental bookkeeping is more complex than most businesses: NHS income, associate splits, lab costs, and partial VAT exemption all need separate treatment.
Attach invoices at the time of payment, not year-end – the single biggest time-saver.
You need all three reports together: P&L (profit), balance sheet (financial health), cash flow (can you pay this week’s bills). Cloud software (Xero, QuickBooks, Sage) is effectively required under Making Tax Digital.
Keep records 6 years (limited companies) or 5 years post-deadline (self-employed) – HMRC can disallow unevidenced claims.
What bookkeeping actually is and what it is not
Bookkeeping is the ongoing recording of every financial transaction in the practice. Money in from patients, the NHS, or insurers. Money out for staff, lab fees, materials, equipment, rent, and everything else. Every transaction logged in the right category on the right date.
This is not the same thing as accounting. Bookkeeping is the recording. Accounting is what your accountant does with those records to produce financial statements, calculate your tax position, and advise on planning. The quality of their work depends entirely on the quality of yours. Messy books produce messy accounts, higher fees, and occasionally an unpleasant letter from HMRC.
Three things people assume about bookkeeping that are wrong
My accountant handles all of this. Your accountant prepares year-end accounts and tax returns using records that someone in the practice has maintained during the year. If those records are incomplete, your accountant spends their time reconstructing them at your expense.
I will sort it out before the deadline. Receipts get lost. Cash purchases of consumables disappear entirely. Trying to rebuild twelve months of records under time pressure in January produces errors and costs significantly more in accountancy time than staying on top of things would have.
Bookkeeping is just data entry. It is also the only reliable way to know how the practice is actually doing. Lab fees creeping up. Cash flow tightening. A treatment category quietly underperforming. The numbers tell a story, but only if someone is reading them regularly.
Problems we find when we open a new dental client’s books
Charles Suthakran, one of the dental accountants at Samera, works with new dental clients from the day they join. He describes the issues he finds almost every single time:
“Invoices. Almost every time. The bank feed shows money going out, but there’s no invoice sitting behind the transaction to tell me what it actually was. You’ve got a payment to a supplier categorised as a lump sum, and no breakdown of what was lab work, what was equipment, what was stock. On paper, it reconciles, but it tells you nothing.”
Charles Suthakran Dental Accountant
The second pattern Charles sees just as consistently is personal and business finances tangled together:
“A card gets used for both, the practice’s and the owner’s. Money moves between personal and business without anyone noting why. It reconciles fine day to day, so nobody worries about it. The problem only shows up when HMRC asks a question, because at that point you have to prove a cost was a business cost, and you can’t do that cleanly if it’s tangled up with personal spending. A legitimate claim you’re fully entitled to gets disallowed simply because you can’t evidence it.”
Charles Suthakran Dental Accountant
This exact scenario is one of the most common and most avoidable mistakes dental practices make, covered in full in our guide to accounting and tax mistakes.
Natasha Gnanapragasam, Director of Operations for Accountancy and Tax at Samera, sees the same problems regularly:
“The books are very disorganised, that’s the most common issue across the board. We end up doing a full tidy-up. We check things, scrutinise things, organise things. And it comes with errors, quite a lot of errors. One of the main concerns I see is not following the correct approach to bookkeeping. We know the nuances: how to allocate NHS income, how to allocate private income. Every particular thing has its own rules. So we check everything, rectify it against the legislation, and correct it. Inaccuracy, not organised properly, not understanding the nuances, those are the key issues.”
Natasha Gnanapragasam Director of Operations
Why dental practice bookkeeping is more involved than most
A dental practice has a more complicated financial picture than a typical small business. At any point you might be handling NHS contract income, private fees, associate fee splits, insurance reimbursements, lab costs, capital equipment, NHS pension contributions, and VAT that only applies to part of what the practice does. Each needs to be recorded in the right category and handled correctly for tax purposes.
Income you need to record correctly
NHS contract payments and UDA activity, including clawback adjustments recorded as income adjustments rather than negative entries. These affect both your accounts and NHS pension calculations.
Private treatment fees, whether individual appointments or plan-based income.
Hygiene income from recall appointments and periodontal treatment.
Cosmetic procedure fees, which may carry different VAT treatment from clinical work.
Product sales such as whitening kits, generally standard-rated for VAT and tracked separately from clinical income.
Associate fee income where your practice retains a share of an associate’s gross earnings.
Expenses that need accurate categorisation
Lab fees and outsourced dental work, typically the largest variable cost in any dental practice.
Dental materials and clinical consumables.
PPE, which HMRC confirmed is a deductible clinical expense.
GDC registration and professional indemnity premiums.
Equipment purchases and ongoing maintenance contracts.
Rent, utilities, and general practice running costs.
What poor bookkeeping actually costs dental practices
Charles describes a situation that shows exactly why records need to be kept throughout the year rather than reconstructed at the end of it:
“We had a practice last year that I always go back to as an example. The issue wasn’t that they did anything wrong as such, it’s that we couldn’t get the data out of them through the year. We chased, it didn’t come, and because nothing was being kept current, nobody had a running picture of what the tax position actually looked like. Then January arrived, we pulled it all together, and the tax figure genuinely startled them. Not because the number was unfair, it was correct, but because they’d had no warning. If we’d had the records flowing through the year, that exact same number would have been something they’d seen coming months earlier and could have set money aside for. Instead, it landed all at once, in the worst month, with no time to plan. The bookkeeping didn’t create the bill. It just meant they found out about it far too late to do anything sensible about it.”
Charles Suthakran Dental Accountant
Natasha has seen the same pattern on a larger and more expensive scale with a group client:
“We had a group client, two or three years ago now, that was in a very big mess. We had to go back two or three years to correct all the bookkeeping. As a result, they ended up paying quite significant fees because all those corrections had to be done. The accounts had to be audited, which meant meeting certain legislation requirements. We managed to do it and it was in proper shape afterwards. But the cost, in time, in fees, in stress, was entirely avoidable.”
Natasha Gnanapragasam Director of Operations
The same discipline matters even more at group level, where corrections have to happen across every site at once. See our guide to taxes for dental groups.
Dental Practice Bookkeeping Checklist: What to Do Weekly, Monthly, Quarterly and Year-End
Consistency matters more than the specific method. A well-maintained spreadsheet beats poorly maintained accounting software every single time. That said, cloud-based software is now effectively required for Making Tax Digital compliance, and it genuinely makes everything easier once it is properly set up.
Your expense categories should reflect how money actually moves through your practice:
Clinical supplies covering materials, lab fees, and consumables.
Staff costs covering wages, employer NI, pension contributions, and training.
Premises covering rent, rates, utilities, cleaning, and insurance.
Professional fees covering accountancy, legal, GDC, and indemnity.
Marketing and patient management software.
Equipment and technology purchases.
Admin costs such as software subscriptions, stationery, and bank charges.
Good bookkeeping works best when it becomes a routine. You do not need to wait until year-end, and you should not rely on your accountant to reconstruct twelve months of records from bank statements, missing invoices and half-remembered payments.
Arun Mehra’s 7 bookkeeping tips for dentists
Here is a practical bookkeeping task list every dental practice should follow
Weekly bookkeeping tasks
Enter all income and expenses into your bookkeeping system.
Reconcile patient payments, supplier payments and bank transactions.
Upload and attach receipts, invoices and supplier bills.
Check that NHS income, private income, plan income and associate income are recorded separately.
Review lab bills, dental materials, PPE and consumables so they are not posted as one generic supplier cost.
Check that personal and business spending have not been mixed.
Flag unusual transactions, refunds, clawbacks, failed payments or one-off equipment purchases.
Monthly bookkeeping tasks
Reconcile all bank accounts, credit cards and finance accounts.
Review your Profit and Loss report.
Check whether lab fees, staff costs or materials are rising faster than income.
Review cash flow for the next month, including payroll, rent, supplier payments, finance repayments and tax.
Verify payroll, PAYE, pension and associate payment records.
Check unpaid patient balances, insurer payments and outstanding supplier invoices.
Send missing documents or unusual transactions to your accountant before they become difficult to explain.
Quarterly bookkeeping tasks
Review VAT position and Making Tax Digital compliance where applicable.
Check that any taxable income, such as product sales or cosmetic procedures, has been treated correctly.
Compare actual performance against your budget or forecast.
Review tax set-aside based on current profit.
Check stock, materials and lab costs for waste or margin pressure.
Review any equipment purchases or finance agreements with your accountant.
Year-end bookkeeping tasks
Before closing your financial year:
Reconcile patient ledgers and outstanding invoices.
Make sure every supplier payment has a matching invoice or receipt.
Review PPE stock, consumables and obsolete materials.
Confirm equipment purchases, depreciation and finance agreements.
Check that GDC fees, indemnity, CPD, professional subscriptions and insurance costs have been captured.
Make sure payroll, pensions, PAYE, P60s and P11Ds are complete.
Identify any personal spending through the business and explain it clearly.
Send complete records to your accountant early, not just before the filing deadline.
Common bookkeeping errors to avoid
Missing invoices or receipts.
Duplicate entries.
Misclassifying personal expenses as business costs.
Posting all supplier payments into broad categories instead of splitting lab work, equipment, stock and materials.
Forgetting to record associate fees properly.
Treating NHS clawback adjustments incorrectly.
Failing to claim allowable expenses such as GDC fees, indemnity, insurance, CPD and training.
Reviewing the books only once a year.
The simple rule is this: every transaction should have a category, a reason and evidence behind it. If you cannot explain it clearly, your accountant may not be able to treat it correctly, and HMRC may challenge it later.
The single habit that makes the biggest practical difference
When asked what one habit makes year-end work go most smoothly, Charles gave a very direct answer:
“Attach the invoice when the payment happens, not at year-end. That’s it. Thirty seconds in the moment versus hours of reconstruction later. The reason year-end becomes painful is almost never the big stuff, it’s hundreds of small transactions where nobody can remember what they were, and we’re emailing back and forth nine months later trying to piece it together. If the paperwork is sitting against the transaction on the day, the year-end is just a review. If it isn’t, it’s an investigation.”
Charles Suthakran Dental Accountant
Arun Mehra, CEO of Samera, makes the point even more simply:
“The smallest bookkeeping habit? Just do it. Regularly, daily, even just a couple of transactions a day, get the books updated and reconciled. You don’t have to suffer during month-end or year-end. Do it daily and there’s no backlog. That’s the key.”
Arun Mehra Samera CEO
A useful test for your own records
If HMRC opened an enquiry tomorrow and asked you to produce a receipt and explanation for every expense claim in your last return, could you? If the honest answer is probably not for everything, that is exactly what your bookkeeping needs to address.

The three financial statements and what they tell you
Once bookkeeping is set up properly, the reports it generates give you a real, live picture of how the practice is performing. These three documents answer different questions, and reading all three together is considerably more useful than relying on any one of them alone.
In this webinar, Arun looks at what you need to understand about your financial statements so you can increase profits in your dental practice.
The Profit and Loss Statement
The Profit and Loss report shows how much your practice has earned, how much it has spent, and the amount of profit made during a set period. Most practices review it monthly or yearly. You can think of it as a regular check up that shows how healthy your practice is.
Most dental practices earn money from several sources such as NHS work, private treatments, hygiene appointments and specialist services. The Profit and Loss report helps you understand the real value of each area. Even small adjustments can improve the overall profit of the practice.
What it shows you:
Whether the practice has made a profit or suffered a loss
Which treatments or services bring in the most income
Where your money is being spent, such as lab fees, staff costs or marketing
How strong and reliable your profit margins are
Warning signs to look out for
Lab fees growing faster than the income from treatments
Staff costs rising above usual industry levels, which are often between twenty and thirty percent
Regular drops in profit that cannot be clearly explained
Balance Sheet
The Balance Sheet gives a snapshot of what your practice owns, what it owes, and the value that remains for you as the owner. Unlike the Profit and Loss report which covers a period of time, the Balance Sheet shows your financial position on a single date.
Dental practices usually invest heavily in equipment including chairs, scanners, autoclaves and digital x ray systems. The Balance Sheet helps you check whether these investments are affordable and how they affect the long term strength of the business.
What it includes
Assets such as dental equipment, money owed to you by patients, and cash in the bank
Liabilities such as loans, outstanding tax and unpaid supplier bills
Equity which is the value of the practice after all debts have been paid
Warning signs to look out for
High short term debts compared to the cash you have available
Old or outdated equipment that is not recorded properly
Large amounts owed by patients or insurers
Cash Flow Statement
Cash flow is different from profit. Your Profit and Loss report might show a profit, yet your bank account may still be under pressure because the cash has not arrived.
Dental practices often face delays in receiving money from insurers or patients who pay in instalments. This can make cash flow uneven. Strong cash flow management ensures you can always pay your team and keep the practice running without stress.
Uneven cash flow from insurer delays and patient instalments is normal in dentistry. Our forecasting service gives you visibility before it becomes a problem, not after.
Whether you have enough to cover wages, bills and day to day costs
Warning signs to look out for
Frequent delays in payments from insurers or patients
A healthy profit on paper but very little cash in the bank
Using an overdraft regularly just to cover monthly costs
How the three reports work together: The P&L tells you whether you made money. The balance sheet tells you how financially sound the practice is. The cash flow statement tells you whether you can pay the bills this week. You need all three to see the full picture. Reviewing them monthly rather than once a year is the difference between managing the practice and reacting to it.
Beyond bookkeeping: using your numbers to manage the practice
Once your bookkeeping is accurate, the numbers can do more than keep you compliant. They can help you understand how the practice is performing and where profit may be leaking.
Useful figures to review include:
Chair utilisation: how well each surgery is being used.
Revenue per patient: whether treatment mix or pricing needs attention.
Lab fees as a percentage of turnover: whether lab costs are rising faster than income.
Hygienist productivity: how much hygiene contributes to overall revenue.
Cash reserves: whether the practice can handle tax bills, equipment repairs or quieter months.
You can also use your bookkeeping records to compare actual performance against budget, plan for equipment purchases, manage debt, and prepare for a future sale or valuation.
This is where bookkeeping becomes more than admin. Clean records give you the information you need to make better decisions.
Accounting software for dental practices
Cloud accounting software is now required for most practices under Making Tax Digital. VAT returns must go through HMRC-recognised software and MTD for Income Tax extends this requirement from April 2026. Beyond compliance, good software makes bookkeeping faster and gives you live visibility over your finances rather than an annual snapshot.
Xero
The most widely used accounting platform in UK dentistry. Connects directly to your bank for automatic transaction imports, handles MTD-compatible VAT submissions to HMRC, integrates with Dentally and Software of Excellence for income reconciliation, and provides real-time financial dashboards. Works well for single-site practices and multi-site groups alike. This is the platform Samera uses for dental finance automation.
QuickBooks
Popular with dental associates and smaller single-site practices. The mobile app is genuinely practical for capturing receipts on the move and tracking mileage between practices. Handles expenses, basic payroll, MTD VAT submissions, and gives running tax estimates that help with Self Assessment planning throughout the year.
Sage
More commonly used by larger practices or groups with complex payroll requirements, or where Sage is already embedded across the wider business. A solid and well-established platform.
Hubdoc
Not standalone accounting software but a document capture tool used alongside Xero. Scans and files invoices, receipts, and supplier bills automatically.

HMRC requires all financial records to be kept for at least six years after the end of the relevant accounting period. An enquiry can be opened into any return, and if supporting records cannot be produced, expense claims can be disallowed and estimated assessments raised.
Most practices reach a point where trying to handle bookkeeping in-house creates more problems than it solves. Signs it is time to think about professional support:
The books fall behind regularly and there is always a year-end scramble to catch up.
The practice has grown and the volume of transactions is hard to manage alongside clinical work.
HMRC deadlines have been missed or have come very close to being missed.
Nobody in the practice has a reliable picture of how it is actually performing financially.
When looking for help, dental-specific experience matters. NHS income structures, associate agreements, partial VAT exemption, and capital allowances on clinical equipment are all areas where a dental specialist produces meaningfully better results than a generalist bookkeeper.
How a dental accountant helps with bookkeeping
A dental accountant like Samera does more than prepare year-end accounts. The right accountant helps you build a bookkeeping system that works throughout the year.
They can help you:
Set up the right chart of accounts for a dental practice.
Separate NHS, private, plan, hygiene, cosmetic and associate income.
Review lab costs, materials, staffing and overheads properly.
Keep VAT, payroll, pensions and tax deadlines under control.
Spot cash flow issues before they become serious.
Make sure capital equipment purchases are recorded correctly.
Give you regular reports you can actually use to run the practice.
This is where dental-specific experience matters. A general bookkeeper may record the transactions, but a dental accountant should understand what those transactions mean in the context of NHS income, associate agreements, lab bills, partial VAT exemption and practice profitability.
Questions to Ask Before Hiring
Do you already work with other dental clients?
Which software do you recommend for my size of practice?
Can you help with both personal and business tax planning?
If you want help setting up, reviewing or cleaning up your dental practice bookkeeping, Samera’s dental accountants can help you build a system that works throughout the year, not just at year-end.
“As an accountant who has been working with dentists for over 20 years, we have seen much change in how book-keeping is done in dental practices. Historically, much of this was done by hand or on excel, but in today’s environment the need to be efficient with one’s time and to be on top of the numbers is imperative.
By doing the monthly bookkeeping accurately, as a dentist you will be able to see the financial trends in your practice, this will then help you make better decisions. These decisions could include increasing prices, reducing costs or looking to improve chair utilisation in your practice. This information can form the foundation of growth for your practice, i.e., should you invest, or should you change the structure of your business – the list is endless, but it’s the numbers that help tell the story.
The key is to implement a system of bookkeeping, so you know each month the numbers, and what is occurring in your practice. Without this, it’s like going on an expedition without a map or a compass.
Having access to up-to-date numbers is essential for any successful dental practice, and with the plethora of options available there is really no excuse to not knowing how you are doing.”
What is the difference between bookkeeping and accounting?
Bookkeeping is the day-to-day recording of every transaction – money in, money out. Accounting uses those records to produce financial statements, calculate your tax position, and advise on planning. The quality of the accounting depends entirely on the quality of the bookkeeping underneath it.
Why is bookkeeping important for dentists?
Dental practices handle NHS income, private fees, associate splits, lab costs, and partial VAT exemption – all of which need separate, correct treatment. Good bookkeeping keeps this organised throughout the year, so tax bills aren’t a shock and your accountant isn’t reconstructing records at your expense.
What expenses should dentists track?
Lab fees and outsourced work, dental materials and consumables, PPE, GDC registration and indemnity, CPD courses, NHS pension contributions, staff wages and auto-enrolment, equipment purchases, and general practice running costs.
Weekly, at minimum. Enter income and expenses, reconcile payments, and attach invoices as they happen rather than at year-end – this is the single biggest time-saver for avoiding a painful January.
Can I claim PPE as a business expense?
Yes. HMRC confirmed that PPE used for clinical purposes is a deductible business expense for dental professionals.
What accounting software do most dental practices use?
Xero is the most widely used platform in UK dentistry, particularly among practices working with specialist dental accountants. QuickBooks is popular with associates and smaller practices. Both are MTD-compatible.
Do I need cloud accounting software?
For most dental practices, yes. Making Tax Digital requires digital record-keeping and HMRC-recognised software for VAT submissions, and MTD for Income Tax extends this from April 2026. Cloud software also makes reconciliation faster and gives live financial visibility throughout the year.
How long must a dental practice keep financial records?
At least six years from the end of the relevant accounting period for limited companies. Self-employed individuals must keep records for at least five years after the 31 January filing deadline for the relevant tax year.
How do I stay compliant with tax regulations?
Keep accurate, up-to-date records, meet VAT, PAYE, and Corporation Tax deadlines, and use MTD-compatible software. A dental specialist accountant will also understand NHS income structures and associate agreements that a generalist bookkeeper may miss.
What are the benefits of hiring a professional accountant?
A dental specialist accountant understands NHS contract income, associate agreements, partial VAT exemption, and capital allowances on clinical equipment – areas where a generalist bookkeeper typically produces weaker results. They also free up time otherwise spent reconstructing records or chasing deadlines.
How do I manage cash flow effectively?
Review cash flow separately from profit – a practice can show a healthy P&L while struggling to pay wages because NHS payments, insurance reimbursements, or patient instalments haven’t landed yet. Monitor incoming and outgoing cash weekly, not just at month-end.
How can I avoid common bookkeeping mistakes?
Attach invoices at the time of payment, keep personal and business spending separate, categorise supplier payments by type rather than as one lump cost, and record NHS clawback adjustments correctly. Reviewing the books only once a year is the most common and costly mistake.
What financial reports are essential for my practice?
The Profit and Loss statement (income, costs, and profit), the Balance Sheet (what you own and owe at a point in time), and the Cash Flow Statement (whether you can pay this week’s bills). You need all three together, not just one.
How can I prepare for year-end accounting?
Reconcile patient ledgers and outstanding invoices, confirm every supplier payment has a matching invoice, review equipment depreciation, and make sure GDC fees, CPD, and insurance costs are captured. Send complete records to your accountant early, not just before the filing deadline.
What should I do if I find discrepancies in my records?
If you find discrepancies in your records, start by reviewing the entries to identify where the error occurred. Check original documents, such as receipts and invoices, against your records. Reconcile your accounts by comparing your financial statements with your bank and credit card statements. Correct any errors you find and document the changes. If the issue persists or is complex, consult with your accountant to ensure accuracy and compliance with financial regulations.

Understanding which expenses you can legitimately claim against tax is one of the most practically useful things any dentist can know. For associates it directly reduces the Self Assessment bill. For practice owners it reduces company taxable profits and feeds into decisions from equipment purchases to staffing levels.
This article covers the rules. For the strategies that use those rules most effectively, see our guide on reducing your dental tax bill.
This article is for general information. It is not specific tax advice for your situation. Tax rules change with each Budget and we link to HMRC directly rather than quoting figures that date quickly.
Which expenses HMRC allows dental professionals to claim and which it does not.
Cash basis versus accruals accounting and why the choice actually matters.
How capital allowances work on equipment purchases.
What records you need to support every claim.
Key Takeaways
Record income in the right category from the start – NHS clawbacks are income adjustments, not negative entries, and cosmetic fees may carry VAT that clinical treatment doesn’t.
Cash basis suits most associates starting out; the real difference only bites once you buy versus lease equipment, since only purchases qualify for capital allowances.
The test for every expense is the same: wholly and exclusively for the business. A personal element usually rules a claim out entirely.
Dental loupes and most clinical equipment qualify in full for the Annual Investment Allowance – claimed in the year of purchase, not spread over time.
Keep every receipt and a mileage log for at least six years – HMRC can open an enquiry on any return, and unsupported claims get disallowed.
Dental income: getting the recording right
Every pound of income needs to be recorded accurately and in the right category. The category matters because it affects VAT treatment, NHS pension calculations, and how clearly your accounts reflect the actual performance of the practice.
NHS contract payments. Fixed income based on UDA values and activity targets. Clawback adjustments for missed UDA delivery are adjustments to income, not separate negative entries. They affect both your accounts and your NHS pension calculations.
Private treatment fees. Generally VAT-exempt when the primary purpose is clinical care. Needs to be recorded separately from NHS income.
Hygiene income. Scale and polish, periodontal treatment, recall appointments. Generally VAT-exempt.
Cosmetic procedure fees. Where a procedure is purely aesthetic with no clinical justification, it may be subject to VAT. This is one of the most frequently mishandled VAT areas in dentistry. See our article on taxes for practice owners for more on the dental VAT position.
Product sales. Whitening kits, toothbrushes, oral care products. Generally standard-rated for VAT and tracked separately from clinical income.
Dental plan income. Monthly capitation payments from plan providers. Usually recognised as spread income over the plan period rather than in one lump sum.
Associate fee splits. If you are a practice owner retaining a share of associate earnings, record each associate’s gross and your share separately.
Cash basis versus accruals: which one applies to you
This distinction rarely gets explained to newly self-employed associates, but it can affect which expenses you claim and in which tax year they fall. Natasha Gnanapragasam, Director of Operations, Accountancy and Tax at Samera, explains the difference and where it matters most practically:
“Cash basis and accruals basis, there’s a real difference in how you recognise things, whether it’s income or cost of sales. Accruals means we do that based on invoices and sales. Cash means it’s only recognised when a transaction happens. So the timing matters, it reflects on your financial statements and gives an accurate picture of how your profit and loss looks. And a real example where it makes a tangible difference is rental equipment versus purchased equipment. When you buy, you can claim capital allowances depending on the nature of the asset. When you lease, you can’t, it just becomes a profit and loss expense item. That’s a significant difference in how the tax relief actually works.”
Natasha Gnanapragasam Director of Operations
For most dental associates, particularly those starting out, cash basis is perfectly adequate and avoids unnecessary complexity. As income grows or the financial situation becomes more involved, your accountant will let you know if switching makes sense. The important thing is to apply one method consistently rather than switching without a good reason. For current cash basis thresholds, check the HMRC website.
Allowable expenses: the rule HMRC applies to everything
One consistent test applies to every expense claim: it must be incurred wholly and exclusively for the purposes of the dental business. Expenses that have a personal element are generally not allowable, though a clearly identified and justifiable business proportion may sometimes be claimable.
Clinical and professional expenses
Lab fees and outsourced dental work, including crown, bridge, denture, and orthodontic appliance fees, fully deductible as a direct clinical cost.
Dental materials and clinical consumables.
PPE including gloves, masks, visors, and scrubs, confirmed by HMRC as deductible for clinical use.
Clinical cameras and digital tools used for treatment documentation.
GDC annual registration fees.
Professional indemnity premiums with Dental Protection, MDDUS, or BDA Indemnity.
CPD courses, both mandatory and voluntary continuing professional development.
Cleaning and laundry of scrubs and uniforms, and their replacement when worn out.
Dental conference fees and professional seminar attendance.
Annual membership fees for the BDA, FGDP, RCS, specialist societies, and local study clubs.
Clinical textbooks, professional journals, and study materials used for your dental work.
Staff and employment costs
Salaries, wages, and bonuses for employed staff.
Employer National Insurance contributions.
Workplace pension auto-enrolment contributions.
NHS pension employer contributions where applicable.
Accountancy and bookkeeping fees. These are themselves a deductible expense.
Legal fees relating to the business.
Practice management software subscriptions.
Bank charges on business accounts.
The business proportion of telephone and internet costs. If you use a personally-owned laptop, printer, or similar equipment for practice admin, the business can also contribute toward the business-use proportion of that cost.
Printing, postage, stationery, and general office equipment such as desks and filing cabinets.
Marketing and advertising costs
Website design, hosting, and maintenance.
Online advertising, including Google Ads and social media campaigns.
Printed marketing materials such as leaflets, signage, and business cards.
Photography or videography used for practice marketing.
Travel expenses
Mileage when travelling between two different practices on the same working day.
Travel to CPD events, dental conferences, professional development courses, and to your accountant.
Train, taxi, and bus fares for business travel.
Parking at workplaces other than your regular practice.
Use of home as office
If you carry out admin at home – managing accounts, ordering materials, handling correspondence – you can claim a portion of your home running costs. Two methods are accepted:
HMRC’s flat rate method: a fixed weekly amount based on hours worked from home, currently starting from £4 a week for the simplest cases.
The actual costs method: a proportion of electricity, heating, water, council tax, and rent or mortgage interest, based on the genuine business-use percentage.
The flat rate is simpler; the actual costs method can produce a larger claim if your business use is significant, but needs the calculation properly documented.
If you operate through a limited company, you’re treated as an employee for expense purposes. From April 2026, employees can no longer personally claim working-from-home tax relief directly from HMRC – your company can still reimburse you tax-free for genuine home-working costs, but the claim route has moved from you to the business. This distinction doesn’t affect sole traders or partnerships claiming use of home as a self-employed business expense.
The ordinary commute from home to your regular practice cannot be claimed. Business mileage is claimed at HMRC’s approved rates – check the current rate on gov.uk as it’s periodically updated. Alternatively, you can claim a business-use proportion of your actual car costs (fuel, repairs, servicing, insurance) rather than the mileage rate, though for most associates the mileage method gives a better result. Model both if your business mileage is high.
What cannot be claimed, including some creative attempts
The rule is clear enough, but creativity in applying it is common. Arun Mehra, CEO of Samera, has seen some memorable examples over the years:
“Someone goes on a course in New York, a very nice course. The course is only two days. But they stay for two weeks and try to claim the whole accommodation, flights, everything as a business expense. That’s a very contentious area and you can’t do that. Another one I’ve seen is someone trying to claim their children’s nursery fees and school fees through the business, somehow it’s business-related because it allows them to work. And I’ve seen a home gym claimed for, because that’s good for their wellbeing and health and therefore good for the business. Good imagination. But none of it qualifies.”
Arun Mehra Samera Founder & CEO
Natasha adds two she sees more regularly:
“Vehicle purchase is a common one, they might just claim 100% without realising it doesn’t fully qualify. And repairs done to their house get claimed because ‘that’s my office’, a new boiler, new windows, new equipment in the home. You cannot do that. Sometimes the funny part is any repair done to the house, they tend to claim those too.”
Natasha Gnanapragasam Director of Operations
The list of what genuinely cannot be claimed:
The commute from home to your regular practice.
Personal clothing that does not qualify as clinical PPE or branded practice uniform.
Client or patient entertainment of any kind.
HMRC fines, penalties, or interest charges on late payments.
Personal spending that has passed through the business account.
Training that leads to a completely new qualification unrelated to your existing dental work.
The dual-use rule: Where something is used for both business and personal purposes, a mobile phone, home broadband, you can generally claim only the business proportion. That proportion needs to be realistic and consistent. HMRC will question splits that look inflated.
The expenses most consistently missed
Arun and Natasha both pointed to the same areas that dental professionals most commonly fail to claim at all:
“Use of home, that’s one of the most common things missed. Associates don’t understand the nuances of how to claim it. We educate them and guide them through it. And travel between practices, that depends on the specifics, but it’s regularly missed too. These are legitimate claims that go unclaimed simply because nobody explained them.”
Natasha Gnanapragasam Director of Operations
This is one of the more common and costly errors dental practices make, covered alongside ten others in our guide to accounting and tax mistakes
“There’s no annual equipment allowance as such, but people don’t realise that if you buy something work-related, it can be claimed to reduce your tax liability. Associates often don’t realise they can claim for dental loupes or equipment they’ve purchased. These are little things but they all add up. The important thing is having proper guidance so you’re claiming everything you’re entitled to.”
Capital equipment (items that last more than a year and are used to run the practice) is not claimed as an ordinary annual expense. Tax relief is provided through capital allowances, and for most dental practices the Annual Investment Allowance means the full cost of qualifying items can be claimed in the year of purchase.
Annual Investment Allowance
The AIA allows 100% of qualifying plant and machinery costs to be deducted in the year of purchase, up to the annual limit. For dental practices this covers dental chairs, X-ray machines, CBCT scanners, CAD/CAM systems, autoclaves, sterilisation equipment, IT hardware, and certain surgery fit-out costs. Fixtures generally qualify; structural building work generally does not. The current AIA limit is £1 million per year. Check the HMRC website before planning any large purchase around it as governments can and do change this figure.
If your capital spending in a year exceeds the AIA limit, the excess isn’t lost – it’s claimed instead through Writing Down Allowances, which spread the tax relief over several years rather than all at once. This is mainly relevant to larger practices or groups with substantial equipment spend in a single year.
Loupes are typically the largest single equipment purchase for most associates and they qualify in full for the AIA. The entire cost can be deducted from your taxable profit in the year of purchase. Keep the invoice and make sure your accountant includes the claim.
Buying versus leasing
Leasing helps with cash flow and avoids a large upfront capital commitment, but the tax treatment differs from buying outright. Lease payments are generally deductible as an ongoing revenue expense rather than through capital allowances. Whether buying or leasing produces better tax relief depends on the asset type, the lease terms, and your profit level in the relevant year. Worth modelling with your accountant before committing to either route on a significant purchase.
Getting the timing right on equipment purchases and reliefs is exactly the kind of proactive planning that reduces your tax bill, rather than reacting to it after the year ends.
For practices providing only exempt clinical treatment, input VAT on purchases generally cannot be reclaimed. The VAT paid on lab fees, equipment, and supplies is a real business cost, not something you recover.
For practices with some taxable income, such as cosmetic procedures or product sales, and with a VAT registration, a proportion of input VAT can be reclaimed through partial exemption calculations. Getting this wrong creates problems in both directions. Under-recovery means paying more VAT than you should; over-recovery creates a liability. For any practice earning meaningful taxable income, specialist VAT advice pays for itself.
Records HMRC expects you to keep
Every expense claim needs supporting evidence. HMRC can open an enquiry into any return, and without records to back up what was filed, claims can be disallowed and estimated assessments raised.
Keep all receipts. Scan paper ones immediately. HMRC accepts digital copies.
Store records for at least six years after the relevant accounting period.
Keep a mileage log for all business travel: date, destination, purpose, and distance.
Note the business purpose of significant expenses, particularly for anything unusual.
If HMRC does open an enquiry, the cost is in the time and professional fees defending it, whether or not anything’s wrong. This cover means Samera handles it on your behalf.
Have you categorised your income sources correctly – NHS, private, hygiene, and product sales recorded separately?
Does every expense claim genuinely pass the wholly-and-exclusively test?
Have you recorded all capital purchases, including loupes and equipment, and claimed the Annual Investment Allowance where it applies?
Are you using the cash basis or accruals method consistently, and does your recordkeeping meet Making Tax Digital requirements where they apply to you?
Have you reviewed use of home, travel between practices, and any other commonly missed claims?
Have you had your claims reviewed by a dental specialist accountant, rather than a generalist?
Getting this right takes proper records and the right guidance, not guesswork. Use this article as your starting point, then speak to a specialist who works with dentists specifically to make sure nothing is missed and nothing is over-claimed.
“There are so many business expenses that can be claimed for when trading as a dentist. But the key is to identify what is business and what is personal to ensure you don’t fall foul of HMRC’s requirements. Use this guide as a starting point and then seek expert help to make the right claims.”
Yes. Loupes are clinical equipment used wholly and exclusively for dental work. They qualify for the Annual Investment Allowance, meaning the full cost can be deducted from taxable profit in the year of purchase.
What is capital allowance, and how does it work for dental practices?
Capital allowances are how tax relief is given on equipment that lasts more than a year, rather than as an ordinary annual expense. For most dental practices, the Annual Investment Allowance means the full cost of qualifying equipment can be deducted from taxable profit in the year of purchase, rather than spread over several years. Spending beyond the annual limit is claimed instead through Writing Down Allowances, spread across future years.
What is the difference between cash basis and accruals accounting?
Cash basis records income when you receive it and expenses when you pay them. Accruals records income when it is earned and expenses when they are incurred, regardless of when cash actually moves. Most associates start on cash basis. Limited companies must use accruals. The choice affects how capital allowances work on equipment.
Are lab fees tax deductible?
Yes. Lab fees are a direct clinical cost and are fully deductible as a business expense in both Self Assessment and Corporation Tax returns.
Are CPD courses tax-deductible?
Yes, where the training maintains or updates your existing professional knowledge. Training that leads to a completely new qualification unrelated to your existing dental work is treated differently and generally cannot be claimed – this is an area HMRC scrutinises closely.
Can I claim home office expenses if I work from home?
Yes, if you carry out admin at home such as managing accounts or handling correspondence. You can use HMRC’s flat rate method, a fixed weekly amount based on hours worked from home, or the actual costs method, claiming a proportion of household running costs based on genuine business use. The actual costs method can produce a larger claim but needs the calculation properly documented.
Can I claim my overseas dental conference as a business expense?
You can claim the conference registration and a proportionate amount of travel and accommodation for the actual conference days. You cannot claim the cost of extending the trip for personal reasons. HMRC looks at the primary purpose of the journey.
Does HMRC accept digital receipts?
Yes. Scanned or photographed receipts are accepted. Most accounting apps capture and store these automatically. The receipt needs to show the amount, supplier, and date of the transaction.
How should I keep records of my business expenses?
Keep every receipt, scanning paper ones immediately since HMRC accepts digital copies, and store records for at least six years after the relevant accounting period. Keep a mileage log recording date, destination, purpose, and distance for all business travel, and note the business purpose of anything unusual. HMRC can open an enquiry into any return, and claims without supporting evidence can be disallowed.
Glossary:
UDA (Unit of Dental Activity): The measure used to calculate NHS contract payments based on treatment activity delivered against agreed targets.
Clawback: An adjustment to NHS income when contracted UDAs aren’t fully delivered – recorded as an income adjustment, not a separate negative entry.
Cash basis: Recording income when you receive it and expenses when you pay them, rather than when they’re earned or incurred. The default starting point for most self-employed associates.
Accruals: Recording income when it’s earned and expenses when they’re incurred, regardless of when the cash actually moves. Required for limited companies.
Wholly and exclusively: The test HMRC applies to every expense claim – it must be incurred entirely for business purposes, with no personal element, for it to be allowable.
Annual Investment Allowance (AIA): The relief that lets you deduct the full cost of qualifying equipment from taxable profit in the year you buy it, rather than spreading it over several years.
Writing Down Allowances (WDA): The relief used once capital spending exceeds the AIA limit in a given year, spreading tax relief over several years instead.
Partial exemption: The VAT calculation used by practices with both exempt clinical income and taxable income (such as cosmetic work or product sales), determining what proportion of input VAT can be reclaimed.

When your company buys a piece of equipment or a business car, you can deduct part, or all, of the cost from your business’s taxable profits.
How much of the cost of the purchase you can deduct from your profit is dependent on several factors. The main points to consider are how you finance the purchase, how you use the vehicle and how environmentally friendly the vehicle is.
Buying a car with a limited company, can be a great way to save on your tax bill. However, it is essential that you understand everything involved before you do.
These are 4 important points you need to know about purchasing a vehicle through a limited company.
How have you financed the purchase?
How you pay for the new business car will affect the tax rate you have to pay on it.
If your company takes out a loan to purchase the vehicle, or it is purchased on hire-purchase, you will only be able to deduct the interest payments as a business expense. You will not be able to deduct the loan itself as a business expense.
If you lease a vehicle for use by the company, but you do not buy it outright, you will be able to claim the monthly payments as a business expense.
Other maintenance costs involved with owning a business car, such as insurance, can be claimed as business expenses for Corporation Tax.
Action Points
Determine the financing method for the business car (loan, hire-purchase, or lease).
Calculate and deduct interest payments from a loan or hire-purchase as a business expense.
Understand that the principal amount of the loan or hire purchase cannot be deducted as a business expense.
If leasing, prepare to claim the entire monthly lease payments as a business expense.
Keep records of all maintenance costs like insurance, as these can be claimed as business expenses for Corporation Tax.
Will the vehicle be used for purely business purposes?
If your car is used solely for business-related purposes, you will be allowed to claim VAT back on the purchase.
If your company vehicle is used for personal purposes outside of the business, this is considered a Benefit-In-Kind (BIK). A benefit-in-kind is anything HMRC considers to be a benefit or a perk on top of your salary. Your business will be taxed on benefits-in-kind.
To reclaim the VAT on your company car you will need to be able to prove to HMRC that the vehicle is not and cannot be used by you or your employees for personal reasons. For example, do you have a company car that is always kept on stand-by at the dental practice for use by the business? That can be considered an exemption.
HMRC does not consider your normal commute to and from work to be a business use, so you will not be able to claim VAT on your vehicle if it is primarily used for commuting.
You can also claim back VAT on vehicles which are used as part of your employee’s routine duties. For instance, vehicles used for teaching people how to drive, taxis and vehicles which are primarily loaned in self-drive schemes.
Action Points
Assess the vehicle’s usage to ensure it’s strictly for business purposes.
Document and maintain proof that the vehicle is not used for personal reasons, to qualify for VAT reclaim.
Be aware that personal use of the vehicle, including commuting, makes it subject to Benefit-In-Kind tax.
Ensure the vehicle is designated for business-only activities, possibly keeping it on-site to reinforce this.
Keep detailed records of the vehicle’s use in employee routine duties to support VAT claims on such usage.
Is your company vehicle environmentally-friendly?
How much tax you pay on your company vehicle is also dependent on the CO2 emissions it produces and the date on which you bought it. This applies to both the tax rate of any benefits-in-kind and the capital allowances you can claim on the cost of buying the vehicle.
For the most part, the more CO2 emissions produced by your company car, the more tax you will have to pay.
However, it is important to remember that the criteria also change according to how old your car is. The newer your car is, the greener it will need to be if you want to claim back on tax.
Action Point
Evaluate the CO2 emissions of your company vehicle to understand the potential tax implications.
Consider the vehicle’s purchase date, as newer cars require lower emissions to qualify for tax benefits.
Explore First-Year Allowances for vehicles that meet eco-friendly standards to deduct 100% of the purchase cost.
Determine if your vehicle qualifies for the Main Rate pool to claim 18% against taxable profits.
Assess if your vehicle falls into the Special Rate band, allowing a 6% claim, aimed at discouraging the purchase of high-emission vehicles.
For instance, this is a table from the Government’s page on business cars:
Cars bought from April 2021
Description of car
What you can claim
New and unused, CO2 emissions are 0g/km (or car is electric)
Vehicles which meet the criteria for First-Year Allowances can have 100% of their cost of purchase deducted from the business’s taxable profits. This is intended to encourage British businesses to go green and purchase environmentally-friendly assets.
The Main Rate pool allows you to claim 18% of the cost of the purchase against your taxable profit.
The Special Rate band allows you to claim just 6% of the cost of the purchase. This is intended to discourage British businesses from buying environmentally-unfriendly assets.
You can calculate the tax band for your company car, according to its CO2 emissions, fuel consumption and date of purchase on the gov.uk website.
How much tax do you need to pay on the fuel for your business car?
If your company owns a business car, you may be required to pay tax on the fuel required.
Again, how much tax you pay on the fuel will depend on the CO2 emissions and whether it is used for private or solely for business purposes.
If your business car is only used for business purposes then you will need to be able to prove this to HMRC. This is one of the reasons why it is so important to keep detailed records like submitted travel expenses and mileage reports. You can use these to show HMRC that all of the consumed fuel was used for business purposes, and not personal use.
If you cannot prove this, or you have indeed used the car (and thus the fuel) for personal reasons, this will be considered a benefit-in-kind. Therefore, you will need to pay tax on the benefit-in-kind fuel usage.
If you can show HMRC that the vehicle has not been used for anything other than company business, you will not need to pay any additional benefit-in-kind tax. You will also be able to reclaim the full VAT amount on the fuel.
You will also not have to pay VAT on the fuel usage if the vehicle is used in certain other circumstances. For instance, cars used for business journeys such as those that are part of the employee’s normal routines like a tradesperson travelling to appointments (this does not include your normal commute to work), or one of your associates travelling to a temporary place of work.
Action Points
Assess the CO2 emissions and usage of the business car to determine fuel tax liability.
Maintain detailed records, including travel expenses and mileage reports, to substantiate business-only use of fuel.
Be prepared to provide HMRC with evidence that the fuel was exclusively used for business purposes to avoid benefit-in-kind tax.
Reclaim full VAT on fuel for vehicles proven to be used solely for business activities.
Understand the specific circumstances under which VAT on fuel usage is not applicable, such as business journeys excluding regular commutes.
Should you buy a business car via your dental practice?
So, are you better off purchasing a business car through your limited company or privately?
Let’s take a look at an example:
Harry is a dental practice owner who owns a limited company who wants to buy a business car at around £40,000.
Buying the car himself:
Harry can declare a £40,000 dividend from his limited company and use that to purchase a car. Harry has to pay 32.5% as a higher-rate taxpayer. This comes out to £13,000 in income tax he has to pay.
Buying the car via a limited company:
Harry could instead buy the care via his limited company. Since there is no dividend declared, there’s no added income tax. Harry’s capital allowances will also allow him to claim back £7,600 in corporation tax. In the current tax year, the benefits-in-kind tax rate is only 1%, meaning the tax on them will be minimal.
This means that Harry is better off to the tune of £20,600 by purchasing his business car through his limited company.
Action Points
Evaluate the financial benefits of purchasing the car through your dental practice’s limited company versus personal purchase.
Consider the tax implications of declaring a £40,000 dividend for personal purchase and the resulting 32.5% income tax.
Explore the option of purchasing the car directly through the limited company to avoid dividend tax and capitalize on capital allowances.
Calculate potential corporation tax savings and the minimal benefits-in-kind tax rate when purchasing through the company.
Assess the overall financial advantage, in Harry’s case, a saving of £20,600, by opting for a company purchase.
Our Expert Opinion
“Buying car through your business is a complex thing. So get the right advice specific to your business and car needs. Do this wrong and you could pay much more tax than needed!”
Yes, a limited company can purchase a car, which can then be used for business purposes. The car becomes an asset of the company, and the company can benefit from tax deductions, such as capital allowances, for the vehicle. However, there are tax implications, particularly if the car is also used for personal purposes, which could trigger a Benefit-in-Kind (BIK) tax for the employee or director using the car.
What are the tax benefits of buying a car through a limited company?
Buying a car through a limited company offers several tax benefits. The company can claim capital allowances, which reduce taxable profits. If the car is used solely for business purposes, VAT on the purchase may be reclaimable. Additionally, running costs like insurance and maintenance can be deducted as business expenses however, if the car is also used personally, a Benefit-in-Kind (BIK) tax applies, which may offset some of these benefits.
How is company car tax calculated?
Company car tax is calculated based on the car’s value (known as the P11D value), its CO2 emissions, and your income tax rate. The P11D value includes the car’s list price, VAT, and any optional extras. A percentage rate is then applied based on the car’s CO2 emissions, which determines the taxable benefit amount. This benefit is added to your income, and you pay tax on it according to your tax bracket.
What is the Benefit-in-Kind (BIK) tax, and how does it apply?
Benefit-in-Kind (BIK) tax applies when a company car is available for personal use by an employee or director. It is calculated based on the car’s P11D value (list price, VAT, and extras) and its CO2 emissions. A percentage rate, determined by the emissions, is applied to this value to calculate the taxable benefit, which is then added to the employee’s income, and they pay tax on it according to their income tax rate.
Can I claim VAT on a company car purchase?
You can claim VAT on a company car purchase only if the car is used exclusively for business purposes, without any private use, including commuting. If there is any private use, you cannot reclaim the VAT on the purchase. However, you may still be able to claim VAT on some of the car’s running costs, depending on the level of business versus private use.
Are there any restrictions on using a company car for personal use?
Yes, there are restrictions on using a company car for personal use. If a company car is used for personal purposes, including commuting, it triggers a Benefit-in-Kind (BIK) tax for the user. This tax is calculated based on the car’s value and CO2 emissions, and the user must pay income tax on this benefit. The company must also report this usage to HMRC and may face additional tax liabilities.
What are the implications of leasing a car through a limited company?
Leasing a car through a limited company can offer tax advantages, such as deducting lease payments as a business expense and reclaiming VAT if the car is used exclusively for business. However, if the car is also used personally, a Benefit-in-Kind (BIK) tax will apply. Leasing might also avoid the large upfront costs associated with purchasing a car. Additionally, the lease may include maintenance, which can simplify budgeting for the company.
How does mileage reimbursement work for company cars?
Mileage reimbursement for company cars involves the company reimbursing employees for business-related travel at a set rate per mile. The reimbursement rate is determined by HMRC and is intended to cover fuel and other running costs. If the reimbursement is within the HMRC-approved rates, it is tax-free. If it exceeds the approved rate, the excess amount may be subject to tax as additional income.
Is it more tax-efficient to buy or lease a car through a company?
Whether it’s more tax-efficient to buy or lease a car through a company depends on factors like the car’s value, CO2 emissions, and how it’s used. Leasing can be more flexible with lower upfront costs and potentially more favorable tax treatment if the car is low-emission. However, buying may offer benefits like capital allowances. The best option varies based on specific business needs and tax implications, so it’s advisable to consult a tax professional.
How do electric vehicles impact company car tax?
Electric vehicles (EVs) can significantly reduce company car tax due to their lower CO2 emissions. They attract a lower Benefit-in-Kind (BIK) tax rate compared to traditional petrol or diesel vehicles. For example, fully electric cars can have a BIK rate as low as 2%, making them a tax-efficient option. Additionally, businesses can claim enhanced capital allowances for electric vehicles, further reducing taxable profits.
What expenses can be claimed for a company car?
For a company car, you can claim expenses such as fuel, maintenance, insurance, road tax, repairs, and depreciation through capital allowances. If the car is used for business purposes, these costs are deductible from the company’s taxable income. However, if the car is also used for personal purposes, the Benefit-in-Kind (BIK) tax may apply to the user.
Are there specific rules for high-emission vehicles?
Yes, there are specific rules for high-emission vehicles. These vehicles typically attract higher Benefit-in-Kind (BIK) tax rates due to their higher CO2 emissions. The percentage applied to the car’s P11D value increases with emissions, leading to a higher taxable benefit. Additionally, high-emission vehicles may have lower capital allowance rates, meaning less immediate tax relief for the company.
What is the difference between pool cars and company cars?
The main difference between pool cars and company cars lies in their usage. Pool cars are shared among employees, used strictly for business purposes, and kept at the company premises when not in use. Because they’re not available for personal use, they don’t attract Benefit-in-Kind (BIK) tax. Company cars, however, are assigned to specific employees and can be used for both business and personal use, which may trigger BIK tax for the user.
Can I sell a company car and what are the tax implications?
Yes, you can sell a company car, but there are tax implications. When you sell the car, any profit or loss compared to its book value will affect your company’s taxable income. If you sell the car for more than its written-down value, you may need to pay Corporation Tax on the gain. Conversely, if you sell it for less, you might be able to claim a tax relief.
How does capital allowance work for company cars?
Capital allowances allow a company to deduct the cost of a car over time from its taxable profits. The rate and amount you can claim depend on the car’s CO2 emissions. Lower-emission vehicles generally qualify for higher allowances, such as the first-year allowance, while higher-emission cars may only qualify for the writing-down allowance at a lower rate. This helps reduce the company’s taxable income gradually as the car depreciates.
Can I claim insurance costs for a company car?
Yes, you can claim insurance costs for a company car as a business expense. These costs are deductible from the company’s taxable income, helping to reduce the overall tax liability. The insurance must be for a vehicle used for business purposes, and if the car is also used for personal purposes, it may be subject to Benefit-in-Kind (BIK) tax.
What records should be kept for company cars?
For company cars, you should keep records of:
Purchase details, including invoices and financing documents.
Running costs like fuel, maintenance, insurance, and repairs.
Mileage logs distinguishing between business and personal use.
VAT records if applicable.
Records of any Benefit-in-Kind (BIK) tax calculations.
Details of any capital allowances claimed.
Documentation of the car’s sale, including sale price and proceeds
How does employee salary sacrifice affect company car tax?
Employee salary sacrifice affects company car tax by reducing the employee’s gross salary in exchange for a non-cash benefit, such as a company car. The employee’s taxable income is reduced, potentially lowering their income tax and National Insurance contributions. However, the Benefit-in-Kind (BIK) tax for the company car still applies, based on the car’s value and CO2 emissions. The salary sacrifice scheme can be tax-efficient, especially with low-emission vehicles.
Can a director use a company car?
Yes, a director can use a company car. However, if the car is available for personal use, it will trigger a Benefit-in-Kind (BIK) tax, which the director must pay based on the car’s value and CO2 emissions. The company can claim related expenses, such as insurance and maintenance, as business deductions, but personal use must be accounted for in the tax calculations.
What are the penalties for incorrect company car tax reporting?
Incorrect company car tax reporting can result in penalties from HMRC, including fines and interest on any unpaid taxes. If errors are found to be deliberate, penalties can be severe, potentially up to 100% of the underpaid tax. Even accidental mistakes can lead to fines, so it’s crucial to keep accurate records and ensure all tax liabilities are correctly reported.

Most dentists are outstanding clinicians who find the financial side of running a practice somewhere between baffling and deeply tedious. That is not a character flaw. Dental training covers occlusion, endodontics, and implantology. It does not cover Corporation Tax, Making Tax Digital, or what an overdrawn director’s loan account actually means. But those things matter, and getting them wrong costs real money.
This guide covers every major area of dental accounting and tax. Think of it as a map: broad enough to orient you across the whole subject, detailed enough to be genuinely useful, with links to deeper articles on each topic. Whether you are a newly qualified associate trying to understand your first Self Assessment, a practice owner wondering whether to incorporate, or a group operator preparing for a sale, start here.
One thing this guide deliberately does not do is tell you which accountant to hire. That is a commercial decision and there is a separate page for it. If you are at the point where you want someone to handle this for you rather than understand it yourself, that is the right next step.
Why dental accounting genuinely needs its own specialism
Arun Mehra, CEO and co-founder of Samera, started the firm specifically around dentistry in 2002. The reason is more personal than most people expect.
“I started Samera back in 2002. I had just got married to Smita, my wife, still my wife and she wanted to start her own dental practice. I was looking for advice out there, and there really wasn’t any. That was the moment I realised what was needed. The lack of specialist expertise in that space was significant. And having a wife who wanted to understand all the financial and business aspects of setting up a practice, that is a great way to learn what dentists actually need to know.”
Arun Mehra Samera CEO
That gap in specialist knowledge has not closed as much as you might expect. A general accountant can absolutely prepare a set of accounts from figures. What they typically cannot do is understand the specific problems those figures are trying to describe.
“They don’t understand the problems you’re facing. They don’t know which reports to run, how the NHS income works, how to pay staff correctly. They don’t even know the basics of what dentistry is, what a crown is, what an implant is, what an inlay is. This terminology is very important for a dental practice. A generalist accountant will be fine for general basic stuff. You really need a specialist.”
Arun Mehra Samera CEO
The financial structure of a dental practice is genuinely more complex than most small businesses. At any given time a practice might be managing NHS contract income, private fees, self-employed associates, employed staff, NHS pension obligations, capital equipment costs, and VAT that applies to some things but not others. Each has its own rules, deadlines, and ways to go wrong.
What this guide covers
Bookkeeping and financial statements
Before any tax planning matters, someone needs to be keeping accurate records of what the practice earns and spends. This section covers what good bookkeeping actually involves for a dental practice, how to read the three main financial statements that your accountant produces, and which software options most practices actually use.
Whether you operate as a sole trader, a partnership, or a limited company shapes how much tax you pay every year, how much personal risk you carry, and how clean an eventual sale or handover would be. This section compares the main options plainly and explains when incorporation makes sense.
Which income sources need to be recorded, which expenses can be legitimately claimed, and how capital allowances work on equipment purchases. Associates and practice owners face different rules here and both are covered.
Self Assessment, payments on account, allowable expenses, and pension planning for self-employed associates. The payments-on-account section alone is worth reading if you are new to self-employment. It is the part nobody explains before it bites you.
Corporation Tax, the director’s loan account, VAT in dentistry, Capital Gains Tax planning, and capital allowances. Includes the dental VAT position explained plainly, which is less obvious than most practice owners expect when they first encounter it.
Group structures, EBITDA and why it matters, group relief, and succession planning across multiple entities. Relevant once you are running more than one site or thinking seriously about a future sale.
PAYE, RTI, NHS pensions, auto-enrolment, and the IR35 risks specific to dental associate arrangements. Payroll is the area where errors accumulate most quietly and tend to show up most expensively.
The reliefs, allowances, and structural choices that genuinely reduce how much tax a dentist pays. Pension contributions, capital allowances timing, salary sacrifice, business structure, and income planning. All legal, all HMRC-approved, most underused.
HMRC deadlines, record-keeping rules, and how Making Tax Digital works in practice rather than in theory. MTD for VAT is already compulsory. MTD for Income Tax is live from April 2026 for higher earners. This section covers what compliance actually requires day to day.
The tax implications of transactions: asset versus share sales, Capital Gains Tax, Business Asset Disposal Relief, earn-out arrangements, goodwill treatment, and Stamp Duty Land Tax. Most of the planning opportunities close once heads of terms are signed, which is why this section matters before any deal begins.
NHS and private pension strategy, the lifetime allowance abolition and what it means for dentists who have not updated their planning, succession options, and Inheritance Tax planning including Business Property Relief and what can lose it.
Common mistakes dentists make with accounts and tax
The eleven most common and most costly errors dental practices make, what causes each one, and what actually fixes it. Poor record-keeping and missed deadlines are the obvious entries. Associate employment status errors and leaving tax planning too late are the ones that tend to cost more.
This guide is the map, not the territory. Every topic above has a full article behind it, and most of what actually determines your tax bill happens in the decisions you make before the year-end, not after it. Whichever stage you’re at, associate, owner, or group, the earlier you understand the ground you’re standing on, the fewer surprises there’ll be later.
Accounts and Tax for Dentists: FAQs
Do dentists need a specialist accountant rather than a general one?
Not legally. But the financial structure of a dental practice is different enough from most small businesses that a generalist will often miss things that cost money. NHS income treatment, associate agreements, partial VAT exemption, NHS pension reporting, and capital allowances on clinical equipment are all areas where dental-specific knowledge changes the outcome.
What’s the most important accounting decision a practice owner makes?
In our experience, business structure has the most long-term financial impact. Whether you operate as a sole trader, partnership, or limited company affects your tax position every year and significantly shapes how a future sale plays out.
What’s different about accounts for an associate versus a practice owner?
Associates are typically self-employed and dealing with Self Assessment, payments on account, and allowable expenses. Practice owners are usually managing Corporation Tax, VAT, the director’s loan account, and payroll for staff. The two roles hit almost entirely different parts of this guide.
Does Making Tax Digital apply to my dental practice?
MTD for VAT has applied since 2022. MTD for Income Tax is live from April 2026 for self-employed individuals above the income threshold, with lower thresholds phasing in over the following two years.
How long do dental practices need to keep financial records?
Self-employed individuals need to keep records for at least five years after the 31 January filing deadline for the relevant tax year. Limited companies need six years from the end of the relevant accounting period.
Is this guide specific to England, or does it cover Scotland, Wales and Northern Ireland too?
The tax rules covered here apply across the UK. NHS contract structures vary between England, Scotland, Wales, and Northern Ireland, which affects some of the NHS-specific points, particularly around notifications when changing business structure. Where there are material differences, the relevant spoke article flags them.

Paying tax is unavoidable. Paying more than you need to is not. Most dentists who end up with larger bills than necessary are not taking risks. They simply have not planned ahead, are not claiming everything they legitimately could, or are using a business structure that no longer suits their income level.
This article covers the strategies that make the biggest practical difference. For the specific rules on which expenses qualify, see our dedicated article on dental expenses and tax relief.

Salary sacrifice: the employer NI saving most practices overlook.
What legitimate tax planning looks like, and where the line is.
Key Takeaways
The tax reduction that matters most happens during the year, not after it – by the time a bill arrives, most of the opportunities to reduce it have already passed.
Pension contributions are the single most consistently underused tool available, cutting your tax bill and building retirement savings at the same time, for associates and practice owners alike.
Salary sacrifice is a genuine, overlooked saving for practices with employed staff – both employer and employee pay less National Insurance on the sacrificed amount.
Every expense claim must pass the same test: wholly and exclusively for business purposes. Pushing a claim without proper documentation almost always ends up costing more in penalties and interest than simply not claiming it.
Tax planning uses the reliefs Parliament has deliberately made available. Tax avoidance uses artificial arrangements HMRC will challenge, sometimes years later – the two are not the same thing, and confusing them is expensive.

What HMRC actually requires before any expense can be claimed
Natasha Gnanapragasam, Director of Operations, Accountancy and Tax at Samera, on the test that applies to every expense claim without exception:
“As far as HMRC is concerned, any expenses that you claim should be exclusively for business purposes. So we need to do a check, a test, against HMRC’s rules to confirm that everything being claimed is approved. We wouldn’t claim for something that doesn’t meet that test. It should be legally correct from HMRC’s point of view. That’s the starting point for everything.”
Natasha Gnanapragasam Director of Operations
The most important principle: plan during the year, not after it
Tax planning is only useful when it is done in advance. By the time a bill has been calculated, almost all of the opportunities to reduce it have already passed. By the time a practice sale has been agreed, most of the tax planning around it is locked in by the decisions made earlier.
The most effective strategies, pension contributions, capital allowances timing, business structure decisions, BADR qualification for a future sale, all require lead time. The dentists who pay the least tax are those who plan throughout the year. Those who pay the most start planning when the bill arrives.
Pension contributions: the single most effective tool
Pension contributions reduce your taxable profit in the year they are made. They cut your tax bill at the same time as building retirement savings. For those paying at the higher rate, the relief is significant. They are HMRC-approved, entirely legal, and in our experience the most consistently underused tax reduction tool available to dentists.
For dental associates
Many associates pay into the NHS Pension Scheme, which provides defined benefit security. But NHS pension alone gives limited flexibility for managing your tax position from year to year. A private pension alongside it gives both the security of defined benefits and real-time tax planning options. Even modest private contributions in a high-earning year produce meaningful tax savings.
Limited company owners can have the company make pension contributions on their behalf. These reduce company profits before Corporation Tax is applied and are not taxed as personal income at the point of contribution. This combination makes employer pension contributions one of the most efficient ways for practice owners to extract value from the company. The pension annual allowance limit applies. Check the current figure on the HMRC website.
Deciding how much to contribute, when, and through which route – personal or employer contributions – depends on your specific income and structure. Our tax planning team works through this with clients each year, rather than leaving it to guesswork at year-end.
Every legitimate business expense reduces taxable profit. Many dentists under-claim not from dishonesty but from uncertainty about what qualifies. For a full breakdown of what is and is not allowable, see our expenses article.
Large equipment purchases including dental chairs, scanners, and surgery fit-outs are claimed through capital allowances rather than as ordinary annual expenses. The Annual Investment Allowance allows the full cost of qualifying plant and machinery to be deducted in the year of purchase. Timing significant purchases to fall before your accounting year-end in a high-profit year is one of the most consistently effective ways to reduce the Corporation Tax bill for that period. Check the current AIA limit on the HMRC website.
This is a legitimate saving that practice owners regularly overlook. Salary sacrifice is an arrangement where an employee gives up part of their cash salary in exchange for a non-cash benefit, most commonly additional employer pension contributions. The employee receives a lower gross salary, which means both they and the employer pay less National Insurance on the amount sacrificed.
How it works in practice
If a dental nurse earning £28,000 a year agrees to sacrifice £1,500 of that salary in exchange for an employer pension contribution of the same amount, her new gross salary is £26,500. The employer pays National Insurance on £26,500 rather than £28,000. The employee also pays less NI and less Income Tax on the reduced salary. The pension contribution goes in at the gross level so the employee receives the same pension benefit from a smaller after-tax cost. For a practice with several employed staff members, these savings add up meaningfully across the team.
The arrangement requires each employee’s contract to be formally amended to reflect the lower salary. It cannot take an employee below the National Minimum Wage. It can also affect mortgage affordability calculations since the salary on paper is lower, which is worth discussing with each employee before implementing.
Employing family members
If a spouse, partner, or adult child genuinely works in the practice, their salary is a deductible business expense in the same way any other employee’s wages are. The salary must reflect real work actually done and be broadly in line with what you’d pay an unrelated person for the same role – HMRC will query arrangements that look like income shifted to a lower tax bracket without genuine work behind it. Done properly, this is a legitimate way to use both spouses’ personal allowances and tax bands rather than concentrating all income on one.
Salary sacrifice arrangements and employing family members both need to be set up correctly through payroll – contracts amended, National Minimum Wage checked, and salaries genuinely reflecting real work. Our payroll team handles this properly from the start.
Everyone has a personal allowance, an amount of income that is not taxed. Above a certain level this allowance starts to reduce, and above a higher level it disappears entirely, creating an effective tax rate on income in that band that is considerably higher than the headline rate. Pension contributions can help keep income below the point where the reduction begins. Check the current threshold on the HMRC website.
If one spouse or civil partner earns below the personal allowance and the other is a basic-rate taxpayer, Marriage Allowance lets the lower earner transfer a portion of their unused allowance to their partner, reducing the couple’s combined tax bill. It’s a small amount individually, but it’s free money left unclaimed by many eligible couples simply because nobody mentions it.
Limited company owners who take income as dividends benefit from a dividend allowance, an amount of dividend income that is not subject to tax. Dividend tax rates increased from April 2026, so a salary/dividend mix that was efficient before that date may no longer be optimal. Review your salary and dividend mix with your accountant each year rather than operating on calculations that may no longer be current.
Donations to registered charities made through Gift Aid let the charity reclaim an additional amount from HMRC on top of what you give, at no extra cost to you. If you pay tax at the higher or additional rate, you can also claim the difference between your rate and the basic rate on the donation through your own tax return – a genuine reduction in your own tax bill, not just a benefit to the charity. Keep records of donations made, as you’ll need them to claim the relief correctly.
When income is received and when expenses are incurred affects which tax year each falls into. For associates with variable income this is worth thinking about each year. For practice owners approaching year-end, timing significant purchases within the right accounting period can produce a meaningful reduction in that year’s tax.
When borderline claims go wrong
Natasha on what happens when clients push for claims without adequate documentation:
“If a client is very adamant that we claim certain expenses, we do a letter of rep, a letter of representation, for everything. Whatever we claim that we’re not entirely comfortable with goes in there.
We advise them on what can and cannot be claimed based on our knowledge of HMRC’s rules. If they want to claim for something without supporting information, that goes in the letter of rep. And as such cases have shown, when they fall into investigation with HMRC, they end up paying penalty and interest charges anyway.
The penalties are very significant, and HMRC charges heavy interest. That ends up being the most expensive outcome, more expensive than simply not claiming the expense in the first place.”
Natasha Gnanapragasam Director of Operations
Business structure
Structure is the foundation of tax efficiency. For the full comparison of what changes at different profit levels and the specific steps involved in incorporation, see our article on choosing the right business structure.
Whether your current structure still suits your income level isn’t a one-off question – it’s worth revisiting as your practice grows. Our practice owner accounts service includes this kind of ongoing structural review, not just annual compliance.
Tax planning means using the reliefs and allowances Parliament has deliberately made available. Tax avoidance means artificial arrangements designed to achieve reductions that were never intended, and HMRC challenges these, sometimes going back many years.
For dentists the boundary is usually clear. Claiming legitimate expenses, making pension contributions, using salary sacrifice, choosing the right business structure, and timing income and expenditure sensibly are all entirely proper. Offshore structures, contrived income-splitting arrangements with no real commercial substance, and schemes that exist purely to reduce tax are not.
The cost of a failed avoidance scheme, including back taxes, interest, penalties, and professional fees to resolve it, is almost always higher than the tax it was supposed to save. If something sounds too good to be true, it almost certainly is.
“The dentists who consistently pay the least tax are not the ones who found a clever scheme. They are the ones who did the straightforward things properly, consistently, and early: set aside money for tax monthly, claimed every legitimate expense, used pension contributions and salary sacrifice strategically, and had their structure reviewed when their income changed.
None of it is complicated. It just requires actually doing it.”
Arun Mehra Samera CEO
None of this requires a clever scheme
Pension contributions, salary sacrifice, claiming what you’re properly entitled to, the right business structure for your income level, and timing purchases sensibly – none of these are secrets, and none of them require pushing a boundary HMRC would challenge. What separates the dentists who consistently pay less tax from those who don’t isn’t cleverness, it’s doing the ordinary things properly and early enough for them to actually work.
Use this article as your starting point, then speak to a specialist who can look at your specific situation – your income level, your structure, and where you are in the year – rather than applying generic advice to circumstances that are genuinely your own.
Pensions, expenses, salary sacrifice, structure – reducing your tax bill properly touches every part of your accounts, not just one decision made once a year. Find out how we work with dentists across all of it.
What is salary sacrifice and how does it save tax for a dental practice?
Salary sacrifice is an arrangement where an employee gives up part of their cash salary in exchange for a non-cash benefit, most commonly additional pension contributions. Because the gross salary is lower, both the employee and the employer pay less National Insurance on the sacrificed amount. For practices with several employed staff members, the combined NI saving across the team can be meaningful.
What is the most effective way for a dental associate to reduce their tax bill?
Making pension contributions consistently is usually the single most impactful step, because they reduce taxable profit immediately and the relief is received in the same year. After that, claiming all allowable expenses properly is the next priority. Many associates consistently under-claim on use of home, mileage between practices, CPD, professional memberships, and equipment.
At what point should a dentist consider incorporating?
When the tax savings from a limited company consistently outweigh the additional accounting costs and compliance obligations. This requires an actual incorporation assessment rather than an assumption that incorporation automatically saves money, because following recent tax changes that is no longer reliably true.
Is there a risk in pushing borderline expense claims?
Yes. If a claim cannot be supported with documentation and HMRC opens an enquiry, the claim gets disallowed and penalties and interest are added on top. The combined cost of penalties and interest often exceeds the original tax saving the claim was supposed to produce.
Can I reduce my tax bill by employing a family member in my practice?
Yes, provided they genuinely work in the practice and are paid a salary that reflects real work done, in line with what you’d pay an unrelated employee for the same role. The salary is a deductible business expense. HMRC will question arrangements that look like income shifted to a lower tax bracket without genuine work behind it.
How does Gift Aid reduce my tax bill?
If you pay tax at the higher or additional rate, Gift Aid donations let you claim the difference between your rate and the basic rate through your tax return, on top of the extra amount the charity itself reclaims from HMRC. Keep records of donations made so you can claim the relief correctly.
What is Marriage Allowance and can dentists use it?
If one spouse or civil partner earns below the personal allowance and the other is a basic-rate taxpayer, the lower earner can transfer part of their unused allowance to their partner, reducing the couple’s combined tax bill. It’s a small saving individually, but it’s often unclaimed simply because people don’t know it exists.
