If you are an NHS dentist with a strongly growing pension, the tapered annual allowance is one of the most expensive tax traps you can walk into without noticing. It quietly shrinks the amount your pension can grow each year before a charge applies, and because NHS pension growth is not the same as the contributions you pay, you can breach it in a year your cash never moved. For 2025/26 the standard annual allowance is £60,000, the same figure for 2026/27, but for high earners the taper can cut that to as little as £10,000. This article explains the two-gate taper, how NHS pension growth is measured, the carry-forward and Scheme Pays options, and the one planning lever that can switch the taper off.
What Is the Annual Allowance for NHS Dentists?
The annual allowance is the maximum your pension benefits can grow in a single tax year before a tax charge applies. For 2025/26 the standard allowance is £60,000, unchanged for 2026/27, and it applies to most dentists in full while their income stays below the taper gates described below.
What trips people up is how NHS pension growth is measured. It is not the contributions you or your practice pay in. Because the NHS scheme is defined benefit, the figure that counts is the capitalised increase in the value of your accrued benefits over the year, known as the "pension input amount". For the 2015 CARE scheme this is broadly the inflation-adjusted rise in your built-up pension, converted to a capital value (the annual pension multiplied by a factor of 16, plus any separate lump sum), so a modest year of contributions can still produce a large input amount. If that input amount exceeds your available allowance, the excess is added to your taxable income and taxed at your marginal rate, which for a higher-rate or additional-rate dentist is a meaningful bill on growth you did not choose.
When Does the Annual Allowance Taper Apply to a Dentist?
The taper has two gates, and both must be passed before your allowance is reduced.
- Gate one, threshold income above £200,000. Threshold income is broadly your total taxable income for the year, minus any personal pension contributions you have made. If your threshold income is £200,000 or less, the taper cannot apply at all, regardless of your adjusted income. This is the filter that protects most dentists.
- Gate two, adjusted income above £260,000. Adjusted income is broadly your total taxable income plus the value of your pension growth for the year (your pension input amount). Only if this is above £260,000 does the taper start to bite.
Where both gates are passed, your £60,000 allowance is reduced by £1 for every £2 of adjusted income above £260,000, down to a floor of £10,000 (reached once adjusted income hits £360,000). The taper is assessed individually, so a high-earning spouse does not aggregate into your figure, although your own private practice profit, rental income, investment income and dividends all feed your totals. For most NHS dentists the taper only becomes relevant with substantial private or property income on top of NHS work, so a principal running a large mixed practice, or an associate with a high UDA volume plus heavy private work, is the typical case, particularly in a year with a large pension input amount.
Tapered Annual Allowance by Adjusted Income Band
The table below shows the reduced allowance at sample adjusted income levels, assuming threshold income is also above £200,000 (without which the taper does not apply).
| Adjusted income | Excess over £260,000 | Reduction (excess ÷ 2) | Tapered annual allowance |
|---|---|---|---|
| £260,000 or below | £0 | £0 | £60,000 |
| £280,000 | £20,000 | £10,000 | £50,000 |
| £300,000 | £40,000 | £20,000 | £40,000 |
| £320,000 | £60,000 | £30,000 | £30,000 |
| £340,000 | £80,000 | £40,000 | £20,000 |
| £360,000 or above | £100,000+ | £50,000 (capped) | £10,000 (floor) |
Worked Example: A Principal Dentist Crossing Both Gates
A principal dentist holds a 50% share in a mixed practice. In 2025/26 her taxable income from the practice is £220,000 with rental income of £30,000 and no personal pension contributions outside the NHS scheme, so her threshold income is £250,000, above the £200,000 gate one limit. Her NHS pension input amount for the year is £50,000, so her adjusted income is £220,000 plus £30,000 plus £50,000, which is £300,000, above the £260,000 gate two limit. Both gates are passed, so the taper applies.
Her adjusted income exceeds £260,000 by £40,000, so the allowance is cut by half of that excess, which is £20,000, leaving an available allowance of £40,000 (£60,000 minus £20,000). Her £50,000 input exceeds this reduced allowance by £10,000. Assuming she has no unused allowance to carry forward, that £10,000 excess is taxed at her marginal rate, so as an additional-rate taxpayer at 45% the charge is £4,500 on pension growth she never received as cash.
Now the planning lever. Suppose she makes a £50,000 gross personal contribution to a separate private (defined contribution) pension. That contribution reduces her threshold income to £200,000, no longer above the gate one limit, so the taper switches off entirely and her allowance returns to the full £60,000, comfortably above her £50,000 input. This is why threshold income, not adjusted income, is so often the decisive number. Any contribution must be within your relevant earnings and available allowance to attract relief, so model it carefully rather than treat it as a blanket fix.
How Is Pension Growth Measured for an NHS Dentist?
For dentists in the 2015 CARE scheme, the pension input amount is the increase in your accrued pension over the scheme year, revalued for inflation, then capitalised. The scheme year runs 1 April to 31 March, aligned to the pension input period for the annual allowance, which differs from the 6 April to 5 April tax year for your other income.
Legacy service in the 1995 or 2008 sections is more involved because those are final salary based, so growth depends on increases in pensionable earnings and length of service, and a pay rise, promotion or backdated pay can spike the input amount sharply in a single year even without any extra contributions. The McCloud remedy adds a further layer for the remedy period of 1 April 2015 to 31 March 2022, because the choice of which scheme rules apply to that period is made at retirement and can adjust earlier input amounts. For how the three sections fit together, see our guide to the 1995, 2008 and 2015 NHS pension sections, and for the remedy itself see how the McCloud remedy affects dentists.
Because the NHS pension is defined benefit, the growth can be large even where you have made no additional voluntary contributions. That is the heart of the problem: a strong earnings year can drive an input amount well above your contributions, and in a taper year it can exceed a reduced allowance you may not realise has applied.
The Money Purchase Annual Allowance
A separate limit, the money purchase annual allowance, is £10,000. It applies only once you have flexibly accessed a defined contribution pension, for example by drawing taxable income from a drawdown pot. Once triggered, it caps tax-relieved contributions to money purchase pensions (such as money purchase AVCs) at £10,000 a year and removes carry-forward for those savings. Your NHS defined benefit accrual is still tested against the standard or tapered allowance, not this figure, but if you take flexible DC benefits alongside NHS service the two interact, so take advice before drawing flexibly.
Carry-Forward: Often the First Line of Defence
Before assuming a charge is due, check carry-forward. You can carry forward unused annual allowance from the previous three tax years, provided you were a member of a registered pension scheme in each of those years, using the current year's allowance first and only then drawing on unused amounts from earlier years, oldest first.
This is what often absorbs a one-off input spike. If your input jumps in a single strong year, perhaps after backdated pay or a pay rise, but your growth was modest in the previous three years, the unused allowance from those years can soak up the excess and leave no charge at all. A tapered year still benefits, because you carry forward the unused part of your reduced allowance. Carry-forward should always be the first calculation, before any thought of Scheme Pays.
What Is Scheme Pays and How Does It Help?
If a charge does arise after carry-forward, you can ask the NHS Pension Scheme to settle it for you in exchange for a permanent reduction in your eventual benefits. This is a "Scheme Pays" election: the scheme pays the tax to HMRC and your pension is reduced later, by scheme-set factors, to reflect what was paid. There are two routes.
- Mandatory Scheme Pays. The scheme must settle the charge where the charge exceeds £2,000 and your pension input amount in the NHS scheme exceeds the standard £60,000 allowance. A charge caused only by the taper, where your input is below £60,000, does not meet this test. The election deadline is 31 July in the year following the relevant tax year.
- Voluntary Scheme Pays. Where the charge is £2,000 or less, or arises only because of the taper below the £60,000 input level, the NHS scheme may still agree to pay at its discretion. This is not guaranteed and can involve more paperwork.
Scheme Pays means you do not need to find the cash now, which can suit you where you lack liquid savings. The trade-off is a smaller pension at retirement, because the amount paid, plus an interest-style adjustment, is recovered from your benefits, so where you can pay from other funds without strain doing so preserves your full pension. There is no single right answer, only a cash-flow judgement worth modelling.
How to Calculate Your Own Taper Risk
Work through it in order. Total your taxable income, deduct your personal pension contributions to reach threshold income, and if that is £200,000 or less, stop, because the taper cannot apply. If it is above £200,000, add your NHS pension input amount to your total taxable income to reach adjusted income, and if that is above £260,000, reduce the £60,000 allowance by half the excess over £260,000 down to the £10,000 floor. Compare that reduced allowance with your input amount, apply any carry-forward, and only the remaining excess is charged. If you do not know your input amount, request a pension savings statement from NHS Pensions through the NHS Business Services Authority portal. Because income fluctuates and the figures interact, this is where a dental-specialist accountant can confirm the numbers and test the contribution lever before any deadline.
What to Do If You Exceed the Annual Allowance
If your pension growth exceeds your available allowance after carry-forward, whether tapered or not, you either pay the charge from your own funds, by reporting the excess on your Self Assessment return and paying by 31 January following the tax year (which preserves your full pension), or you use Scheme Pays as set out above. Note that you must report the charge on your Self Assessment return even where you elect for Scheme Pays, because the election is a separate process from reporting, and missing the reporting deadline can bring penalties and interest.
Some dentists with heavy private income consider reducing NHS pensionable earnings, or even opting out of the scheme for a period, to manage input amounts. That is a major decision with long-term consequences for accrual and death-in-service cover, and it should never be taken to dodge a single year's taper that carry-forward or a contribution could have absorbed. Take advice first.
Common Misunderstandings About the Taper
The most expensive myth is that the taper is based on your NHS contributions. It is not. It is based on your pension input amount, the capitalised growth in your benefits, which can be far larger than the contributions paid: a 2015-scheme dentist with a good earnings year can see an input amount of £40,000 to £60,000 even where employee contributions are a fraction of that. For how contributions and tax relief sit alongside the allowance, see our guide to dentist pension contributions and tax relief.
A second myth is that having no private pension contributions keeps you safe. It does the opposite for gate one, because every pound of personal contribution reduces threshold income, so a high earner with no contributions and large NHS growth can be more exposed, not less, than a colleague who contributes.
How a Dental Accountant Can Help
Navigating the taper needs accurate income projections, a reliable pension input amount, a carry-forward review across three years, and awareness of the Scheme Pays deadlines. A general accountant may not be fluent in the NHS defined benefit rules or their interaction with the McCloud remedy, whereas a dental-specialist accountant can model scenarios, test whether a contribution closes gate one, and make sure every reporting requirement is met. If you own a practice, the taper also touches profit extraction: higher dividends or salary can push adjusted income over the line while doing nothing to reduce threshold income, so modelling extraction and pension growth together is the only way to see the full picture.
Final Thoughts
The tapered annual allowance is a genuine risk for NHS dentists whose threshold income climbs above £200,000, cutting the allowance from £60,000 to as little as £10,000 and taxing pension growth you cannot control. Understand the two gates, measure your pension input amount rather than your contributions, and check carry-forward before anything else. Scheme Pays can defer the cost at the price of a smaller pension, but a well-timed personal contribution that closes gate one can remove the charge altogether, so review your income and pension growth for the current and coming years now, while those levers are still open.
