If you're a high-earning dentist, the part of pension tax that catches you out isn't the standard annual allowance. It's the taper.
Once your income climbs past a certain point, the £60,000 annual allowance starts shrinking, and a strong year in your practice can quietly hand you a tax charge you never saw coming. NHS pension growth on a defined benefit scheme is hard to predict, so it's easy to breach an allowance you didn't realise had been cut in half.
This guide is for principals, high-earning associates and dentists with private income on top of NHS work. We'll keep it narrow: how the taper works in 2026/27, the exact income thresholds, a worked example, and how to handle a charge without finding the cash yourself. If you need the basics first, read our explainer on the NHS pension annual allowance before this one.
What is the tapered annual allowance for dentists?
The tapered annual allowance reduces your standard £60,000 pension allowance once your income is high enough, cutting how much your pension can grow each year before a tax charge applies. It can fall as low as £10,000.
The annual allowance is the cap on how much your pension can grow in a tax year with tax relief. For 2026/27 the standard allowance is £60,000, confirmed on gov.uk. Most dentists never think about it. But the taper is built for higher earners, and a busy practice owner or a well-paid associate can land squarely in its range.
The thresholds and the £60,000 standard allowance were left unchanged at the November 2025 Budget, so the 2026/27 figures match 2025/26.
What are the taper thresholds for 2026/27?
Two income tests decide whether the taper bites. You only lose allowance if you're over both.
| Test | 2026/27 figure | What it does |
|---|---|---|
| Threshold income | £200,000 | If your threshold income is at or below this, the taper never applies, whatever your adjusted income |
| Adjusted income | £260,000 | The taper starts reducing your allowance once adjusted income passes this point |
| Standard annual allowance | £60,000 | The starting allowance before any taper |
| Minimum tapered allowance | £10,000 | The lowest your allowance can fall to |
These figures come from HMRC's guidance on the tapered annual allowance and the annual allowance overview.
The key point: if your threshold income stays at or below £200,000, you keep the full £60,000 no matter how high your adjusted income is. That £200,000 gateway is what saves a lot of dentists, and it's why pension contributions you make personally can matter (more on that below).
How is the tapered allowance worked out?
If you're caught by both tests, your allowance falls by £1 for every £2 your adjusted income exceeds £260,000, as set out on gov.uk.
Work down from £60,000:
- Adjusted income £280,000: £20,000 over the limit, so allowance drops by £10,000 to £50,000.
- Adjusted income £300,000: £40,000 over, so allowance drops by £20,000 to £40,000.
- Adjusted income £360,000 or more: the reduction hits £50,000, so you're at the £10,000 floor and it won't fall further.
Illustrative example: a high-earning practice principal
Priya is a dental practice principal. For 2026/27 her adjusted income works out at £290,000 and her threshold income is above £200,000, so the taper applies.
- Adjusted income over £260,000: £290,000 - £260,000 = £30,000
- Allowance reduction: £30,000 / 2 = £15,000
- Tapered annual allowance: £60,000 - £15,000 = £45,000
Her NHS pension input amount (the measured growth in her benefits) for the year is £58,000. That's £13,000 above her £45,000 tapered allowance.
She has £8,000 of unused allowance to carry forward from earlier years, which she uses first. That leaves £5,000 chargeable. As an additional-rate taxpayer the charge is added to income taxed at 45%, so:
- Taxable excess: £13,000 - £8,000 = £5,000
- Annual allowance charge: £5,000 x 45% = £2,250
The 45% additional rate applies to taxable income over £125,140 for 2026/27, per gov.uk. This is an illustrative example, not a real client, and the actual rate on your excess depends on your own income.
What counts as threshold income and adjusted income?
These two measures are not the same as your taxable income, and getting them wrong is the most common mistake we see.
Broadly, and as explained in HMRC's taper guidance:
- Threshold income is your total taxable income from all sources (NHS pensionable pay, associate or self-employed profits, private practice income, dividends, rental income, savings interest) less certain reliefs, including the gross amount of personal pension contributions you pay.
- Adjusted income is broadly your threshold income plus the value of your pension growth for the year. For NHS members that means adding back your pension input amount, so the figure can be much higher than the income hitting your bank account.
The practical takeaway for dentists: because adjusted income includes NHS pension growth you never receive as cash, you can be over £260,000 on adjusted income while your real take-home is far lower. If you want to sanity-check the income tax position behind these numbers, our income tax calculator is a quick starting point, though it won't model the pension input itself.
Why does NHS pension growth surprise dentists?
Your NHS pension is a defined benefit scheme, so the growth that counts towards the allowance is a calculated figure, not the contributions you pay. That figure can swing sharply with inflation.
In the 1995 and 2008 sections, past earnings are uprated each year by a dynamising factor. In the 2015 scheme, your built-up pension is revalued each year. When inflation is high, the way the opening and closing values of your pension are measured across the tax year can produce a large pension input amount, even in a year where your pay barely moved.
This is why a dentist can breach an allowance without doing anything differently: a big input figure, combined with a tapered allowance below £60,000, is the trap. It also cuts the other way. In a low-inflation year the growth can be modest. The lesson is to check the actual input figure each year rather than assume.
How do you find out if you've exceeded the allowance?
The NHS Business Services Authority (NHSBSA) issues an annual allowance pension savings statement, but only automatically in certain cases, and there's a lag.
Provided NHSBSA receives the membership and pay information it needs from your employer or practice in time, it writes to members who have exceeded the standard £60,000 allowance in a scheme by the HMRC deadline of 6 October following the tax year, per NHSBSA guidance.
Two warnings for high earners:
- A statement is typically triggered by exceeding the standard £60,000 allowance. If your allowance is tapered to, say, £40,000, you could have a charge without an automatic statement, because your growth was under £60,000. You may need to request a statement.
- If you're in more than one scheme section, or you have private pension savings too, you have to add the inputs together yourself.
You report any charge on your Self Assessment return using HMRC helpsheet HS345, which also explains the pension savings tax charge boxes on the return.
Can you use carry forward to reduce the charge?
Yes. You can carry forward unused annual allowance from the previous three tax years, used earliest first, as long as you were a member of a registered pension scheme in those years. This often wipes out a charge entirely.
Carry forward is set out on gov.uk. A few points that matter for tapered years:
- You use the current year's allowance first, then carry forward from the oldest of the three prior years.
- The allowance you carry forward from a tapered year is that year's tapered figure, not the full £60,000.
- You can't carry forward from a year in which you held no registered pension at all.
For high earners whose allowance is tapered every year, carry forward can be thin, because there's little spare allowance in the earlier years either. That's where planning ahead pays off.
How do you pay a charge with Scheme Pays?
If the charge is large, you don't have to find the cash yourself. Scheme Pays lets the NHS scheme settle the charge with HMRC in exchange for a permanent reduction in your pension.
There are two routes, explained by NHSBSA and in HMRC's guidance:
- Mandatory Scheme Pays. Available where your charge for a single scheme exceeds £2,000 and your growth in that scheme exceeded the standard £60,000 allowance. The scheme must pay it, and the scheme becomes responsible for paying HMRC on time.
- Voluntary Scheme Pays. Used where mandatory doesn't apply, for example a charge that arises only because your allowance was tapered below £60,000. Here you stay responsible for the charge and any interest if HMRC is paid late.
The election deadline matters. You must submit your Scheme Pays election (form SPE2) to NHSBSA by 31 July in the year following the tax year of the charge, the HMRC statutory deadline, per NHSBSA. So a 2026/27 charge has a Scheme Pays election deadline of 31 July 2028. NHSBSA cannot extend the mandatory deadline because it's set in legislation.
Deadline calendar for a 2026/27 annual allowance charge
| Date | What happens |
|---|---|
| 6 April 2027 | 2026/27 tax year ends; pension growth is measured to this date |
| By 6 October 2027 | NHSBSA issues a pension savings statement if you exceeded the standard £60,000 allowance |
| 31 January 2028 | Self Assessment filing and payment deadline for 2026/27; report any charge on your return |
| 31 July 2028 | Statutory deadline to submit a Scheme Pays election (form SPE2) for the 2026/27 charge |
Dates are based on HMRC's Self Assessment deadlines and the Scheme Pays and statement timings above.
Does the McCloud remedy change anything?
For some dentists, yes. The McCloud remedy can reopen old annual allowance positions, which may mean a refund or a small extra charge for past years.
Following the public service pensions remedy, members' pensionable service from 1 April 2015 to 31 March 2022 was rolled back into the legacy NHS scheme (the 1995/2008 Scheme) from 1 April 2024. NHSBSA recalculates the pension input amounts and annual allowance for each remedy-period tax year, explained on gov.uk.
HMRC runs a digital service so affected members can reassess annual allowance charges across the remedy years, claim a refund of overpaid charges, or pay any underpaid amounts for the relevant years. If you paid an annual allowance charge between 2015/16 and 2021/22, it's worth checking whether your position has moved. This is separate from your current 2026/27 taper position, but it can affect the carry forward figures you rely on.
Pension tax for dentists rewards getting ahead of it. If your income is anywhere near £200,000 and you'd rather not be surprised by a charge, our tax advisory team works with dentists on exactly this: modelling the taper, checking carry forward, and getting Scheme Pays elections in before the deadline.

Frequently asked questions
What is the annual allowance taper for dentists in 2026/27?
It's a reduction in your £60,000 pension annual allowance that applies if your threshold income is over £200,000 and your adjusted income is over £260,000. The allowance falls by £1 for every £2 of adjusted income above £260,000, down to a minimum of £10,000.
At what income does a dentist hit the minimum £10,000 allowance?
The minimum £10,000 tapered allowance is reached when adjusted income is £360,000 or more, because the £50,000 maximum reduction applies at that point. It cannot fall below £10,000.
Does the taper apply if my threshold income is below £200,000?
No. If your threshold income is at or below £200,000 you keep the full £60,000 allowance for 2026/27, however high your adjusted income is. Gross personal pension contributions reduce threshold income, which can keep some dentists under the £200,000 gateway.
How do I pay an annual allowance charge without finding the cash?
You can use NHS Scheme Pays, where the scheme settles the charge with HMRC in return for a permanent reduction in your pension. You must submit a Scheme Pays election (form SPE2) by 31 July in the year following the tax year of the charge.
Will I always get a statement if my allowance is tapered?
Not necessarily. NHSBSA generally issues a statement automatically only where you exceeded the standard £60,000 allowance. If your allowance was tapered below £60,000 but your growth stayed under £60,000, you may have a charge with no automatic statement and should request one.
