Payroll and Auto-Enrolment for Dental Practice Staff: Getting Workplace Pensions Right

Once a dental practice has staff on the payroll, two obligations run quietly in the background every single month, and both have hard rules and real penalties. The first is PAYE under Real Time Information, the system for reporting pay and deductions to HMRC on every payday. The second is the workplace pension under automatic enrolment, the duty to enrol eligible staff into a pension and contribute. Neither is difficult once set up correctly, but both are unforgiving about deadlines and figures, and a practice owner who treats them casually can accumulate penalties without realising.

This guide explains how payroll and auto-enrolment actually work for a dental team. We cover the RTI reporting rhythm, the contribution figures that matter, the £10,000 trigger and the qualifying-earnings band, the categories of worker you have to assess, and the compliance steps, the declaration of compliance and re-enrolment, that keep you on the right side of The Pensions Regulator. The companion to this page is our guide to employing your first dental nurse or practice manager, which builds the full loaded cost of a hire; this page is about running the payroll and pension correctly once that hire is made.

PAYE under Real Time Information

Employing staff means operating PAYE. You register with HMRC as an employer before the first payday, then for every pay run you:

• Deduct income tax and employee National Insurance from each employee's wages according to their tax code and earnings.
• Calculate the employer National Insurance due (15% above the £5,000 secondary threshold from 6 April 2025).
• Submit a Full Payment Submission to HMRC on or before the payday, reporting the pay and the deductions.
• Pay over the deductions and employer NIC to HMRC monthly, or quarterly if you are a small employer.

The phrase that matters is on or before the payday. RTI is a per-payday obligation, not the old year-end exercise, and submitting late or paying HMRC late attracts penalties. A practice that pays staff weekly reports weekly; one that pays monthly reports monthly. The discipline is to run the payroll, file the FPS and set aside the PAYE liability every cycle, so that nothing builds up and no submission is missed. Clean RTI payroll also feeds your bookkeeping directly, which matters for the accounting software and integration across the practice.

Auto-enrolment: who must be enrolled

Alongside payroll runs the automatic enrolment duty. You must assess every worker and automatically enrol any eligible jobholder: an employee aged between 22 and State Pension Age earning over the earnings trigger of £10,000 a year (2025/26). But the assessment is not limited to the obvious eligible staff. Workers fall into categories by age and earnings:

• Eligible jobholders (22 to SPA, earning over £10,000): must be auto-enrolled with an employer contribution.
• Non-eligible jobholders (for example earning between the lower band limit and the trigger, or outside the age band): have a right to opt in with an employer contribution.
• Entitled workers (earning below the lower limit): have a right to join a scheme, though without a compulsory employer contribution.

So you assess every worker, not just the full-timers, and act according to their category. A part-time nurse, a Saturday receptionist or a junior on a low wage may still have rights, and ignoring them is a compliance breach. The trigger is reviewed each year, so check the current figure for the year in question, although it has been held at £10,000 for several years.

The three worker categories in more detail

The assessment that sits at the heart of auto-enrolment deserves a closer look, because dental practices have varied workforces, full-time nurses, part-time receptionists, Saturday staff, hygienists, a practice manager, and each worker has to be placed in the right category at each pay run. The category depends on two things: age and earnings.

An eligible jobholder is aged 22 to State Pension Age and earns above the £10,000 trigger. These are the workers you must automatically enrol with an employer contribution, and they are the obvious target of the regime. A non-eligible jobholder is someone who, broadly, earns above the lower edge of the qualifying-earnings band but below the trigger, or is in the 16-to-21 or SPA-to-74 age range above the trigger; they are not auto-enrolled but have a right to opt in, and if they do, you must contribute. An entitled worker earns below the lower band limit; they have a right to join a scheme, but you are not obliged to contribute for them.

The reason this matters for a dental practice is that a part-time or junior worker is not automatically outside the system. A receptionist working two days a week who asks to opt in must be enrolled with an employer contribution if they are a non-eligible jobholder. A worker who turns 22, or whose hours increase so their pay crosses the trigger, becomes an eligible jobholder and must be enrolled from that point. So the assessment is dynamic, run every pay period, not a one-time judgment made when someone is hired. A practice that assesses only its full-time staff and ignores the rest is exposed.

The contribution figures

For enrolled staff, the minimum total contribution is 8% of qualifying earnings, split as follows:

• Employer: at least 3% of qualifying earnings.
• Employee: 5% of qualifying earnings (including the basic-rate tax relief added to their contribution).

Qualifying earnings are the band between £6,240 and £50,270 for 2025/26, so contributions are calculated on the slice of pay within that band, not the whole salary. For a nurse on £28,000, qualifying earnings are roughly £21,760, and your minimum 3% employer contribution is about £653 a year. You can pay more than the minimum, and some practices do as a recruitment and retention tool, but you cannot pay less and still meet the duty. These figures have been stable since the minimums reached 8% in April 2019, but the qualifying-earnings band is reviewed annually, so date-tag the limits as 2025/26 and check the current year.

Compliance: declaration and re-enrolment

Auto-enrolment is not a one-off setup; it has recurring compliance steps with The Pensions Regulator:

• Declaration of compliance. A new employer must submit a declaration to the regulator within a set period of becoming an employer, confirming how the duties were met and which scheme was used. Missing it is a breach in its own right, separate from actually enrolling people.
• Re-enrolment. Roughly every three years you must re-enrol eligible staff who had opted out, putting them back into the scheme, after which they may opt out again. Each cyclical re-enrolment is accompanied by a re-declaration of compliance.
• Ongoing assessment. Every pay run you reassess workers, because someone can cross the trigger, turn 22, or join, at which point the duty applies to them.

This is why auto-enrolment is best treated as a live obligation rather than a box ticked once. The dates, the initial declaration, each three-yearly re-enrolment, have to be diaried, because the regulator treats a missed declaration as seriously as a missed enrolment.

The tax treatment of your pension contributions

The employer side of the workplace pension is genuinely tax-efficient. Your employer pension contributions for staff are an allowable business expense, deductible in arriving at taxable practice profit on a paid basis, and they carry no National Insurance. So the 3% you pay into the workplace pension reduces your taxable profit and gives relief at your marginal rate, making it one of the more efficient elements of the cost of employing people. The same favourable treatment applies to contributions for a genuinely employed spouse, which is one reason employer pension contributions feature in spouse-employment planning, covered in our guide to employing a spouse in a dental practice at a market rate. The wider pension-relief mechanics sit alongside the personal pension and annual allowance rules in our guide to NHS pensionable pay for dentists.

Opt-outs and the cash that comes back

An employee who has been automatically enrolled can opt out, and there is a specific mechanism for it that practice owners should understand. If a worker opts out within the opt-out window (a set period after enrolment), they are treated as never having joined, and any contributions already deducted are refunded. If they opt out later, they stop future contributions but the money already in the pension stays there. The important point for the employer is that you cannot encourage or induce staff to opt out: doing so is a breach of the rules, because the whole regime is built on enrolment being the default. So you enrol eligible staff, you let them opt out if they genuinely choose to, and you stay neutral about the decision.

For a dental practice this matters because some staff, particularly lower earners or those near retirement, may prefer the take-home pay to the pension and choose to opt out. That is their right, and it reduces the employer contribution you pay for them. But it must be their decision, made through the proper process, not something you steer. And because of re-enrolment, a worker who opts out will be put back in roughly every three years and must opt out again if they still wish to, so an opt-out is never permanent. Keeping clean records of who opted out, and when, is part of running the scheme properly.

How payroll and auto-enrolment fit together

It helps to see payroll and the pension as a single monthly process rather than two separate jobs, because in practice they run together. Each pay run, the payroll calculates the gross pay, deducts income tax and employee National Insurance, works out the employer National Insurance, and also assesses each worker for auto-enrolment, calculates the pension contributions on qualifying earnings, and processes them to the pension scheme. Modern payroll software handles both in one workflow, which is why good accounting and payroll software integration is so valuable: it removes the risk of the two halves falling out of step.

When they are handled separately, errors creep in: a worker enrolled in the pension but with the wrong contribution, or a payroll change that is not reflected in the pension assessment. When they run as one process, the assessment, the deduction and the contribution all flow from the same pay data, and the quarterly and annual figures reconcile cleanly. For a dental practice, the practical advice is to choose a payroll solution, whether software run in-house or a bureau, that does payroll and auto-enrolment together, and to feed it accurate hours and pay each cycle. That single integrated process is what keeps both HMRC and The Pensions Regulator satisfied.

What it costs to get wrong

The penalties make the case for getting this right. The Pensions Regulator can issue compliance notices and financial penalties for failing to enrol eligible staff, failing to make the required contributions, or failing to complete the declaration of compliance, and may require backdated contributions to put employees where they should have been. On the payroll side, HMRC penalises late RTI submissions and late payment of PAYE. None of this is intended to catch out a careful employer, but a casual one, who forgets to enrol a part-timer who crossed the trigger, misses a re-enrolment date, or files an FPS late, can accumulate breaches. Because both duties are recurring, the risk is ongoing, not just at setup, which is the single most important thing for a practice owner to internalise.

Postponement and the first three months

One useful flexibility is worth knowing: postponement. An employer can postpone the automatic enrolment assessment for a new worker, or at the practice's start as an employer, for up to three months. This is handy for a dental practice with short-term or probationary staff, because it can avoid enrolling someone who leaves quickly, and it can align enrolment with a convenient payroll date. The worker still has a right to opt in during the postponement period if they choose, so postponement defers the employer's enrolment duty without removing the worker's rights, and you must give the worker proper notice of the postponement.

Postponement is not a way to avoid the duty, only to time it sensibly, and at the end of the postponement period you must assess the worker and enrol them if they are then an eligible jobholder. For a practice taking on its first staff, used carefully it can smooth the administrative start, but it has to be applied correctly with the right notifications, so it is one to set up with your payroll provider rather than improvise. The key point is that the duty is deferred, not escaped: an eligible worker still gets enrolled, just from a slightly later, chosen date.

Choosing a qualifying pension scheme

Auto-enrolment requires you to use a qualifying scheme, and the choice is one a practice makes once and then lives with, so it is worth a moment's thought. Many small employers use one of the large master-trust schemes set up for auto-enrolment, which are designed to accept any employer, handle the administration, and integrate with payroll software. The practical criteria are that the scheme meets the qualifying rules, integrates with your payroll so contributions flow automatically, and offers reasonable investment options and charges for your staff, who are after all the members.

For a dental practice the key is integration: a scheme that connects cleanly to your payroll software turns the monthly contribution into an automatic step, while a poorly integrated scheme creates manual work and error risk every pay run. The owner does not need to become a pensions expert, but choosing a well-established, payroll-integrated qualifying scheme at the outset saves a great deal of friction later. If you outsource payroll, your provider will usually recommend or operate a scheme they work with smoothly, which is generally the path of least resistance and least risk.

Salary sacrifice and going above the minimum

Two refinements are worth knowing once the basic scheme is running. First, salary sacrifice: an employee can agree to give up part of their salary in exchange for a larger employer pension contribution, which can be more National-Insurance-efficient for both the employee and the practice, because the sacrificed salary is not subject to NIC. It has to be set up correctly as a genuine contractual change and is not suitable for every employee, particularly lower earners near the minimum wage, but for higher-paid staff or a practice manager it can be a tax-efficient enhancement. Second, going above the minimum: a practice can contribute more than the 3% minimum as a deliberate retention tool. An enhanced employer pension is a tax-efficient reward, deductible and free of NIC, that staff value highly, and it can be a cheaper way to improve a package than an equivalent salary rise once employer NIC on the salary is counted. Both refinements sit on top of the compliant baseline, not instead of it, so get the auto-enrolment minimum running correctly first, then consider whether to layer these on.

Should you outsource payroll and auto-enrolment?

For most dental practices, the answer is yes. A payroll provider or your accountant can run the monthly RTI payroll, calculate and process the pension contributions, manage enrolments, opt-outs and re-enrolment, and complete the declaration of compliance, all to deadline. Outsourcing removes the single biggest risk, a missed submission or re-enrolment date, and keeps you compliant without having to master the detail yourself. The cost belongs in the loaded cost of employing staff, and given the penalties for getting it wrong, it is generally money well spent. A practice that runs payroll in-house can do so perfectly well with good software, but it then owns the deadlines, so the choice is between paying for the service or owning the compliance risk.

Run the rhythm and stay compliant

Payroll and auto-enrolment are not complex once the structure is in place, but they are relentless: an FPS on or before every payday, contributions every pay run, an assessment of every worker each cycle, a declaration of compliance, and re-enrolment every three years. The practices that stay compliant are the ones that build the rhythm into their systems, whether in-house or outsourced, and treat the duties as live obligations rather than a one-time setup. A specialist dental accountant can establish the payroll and the workplace pension correctly, keep the compliance calendar, and make sure the contributions are claimed as deductions, so your team is paid and pensioned properly and the regulator never has cause to look twice.

It also helps to remember why these duties exist: they ensure that the people who keep a dental practice running, the nurses, receptionists and managers, are paid correctly and build a pension for their own future. Seen that way, payroll and auto-enrolment are not just compliance overhead but part of being a responsible employer, and the staff who feel properly looked after are the ones who stay. The administrative discipline and the human benefit point in the same direction. A practice that runs its payroll and pension cleanly, contributes properly, and perhaps a little above the minimum where it can afford to, builds a team that is both compliant on paper and genuinely loyal in practice, which is worth far more than the cost of getting the systems right.
