Payroll, Pensions and Staff Compliance for Dental Practices
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.
