If you're a consultant, GP, hospital doctor or dentist with NHS pension membership, there's a good chance you've had a brown envelope from NHS Pensions telling you your pension has "grown" by tens of thousands of pounds, even though you never saw a penny of it in cash. Then comes the worry: do you owe tax on it?
This is the NHS pension annual allowance problem, and it catches high-earning clinicians more than almost any other group. The rules are fiddly, the numbers are large, and getting it wrong can mean an unexpected bill or, worse, paying a charge you didn't actually have to.
Here's a plain-English walk-through of how the annual allowance works, when the "tapered" version bites, how to read your pension savings statement, and what your options are if you're over the line. All the figures here are for the 2025/26 tax year.
What is the NHS pension annual allowance?
The annual allowance is the most your pensions can grow in a tax year before a tax charge applies. For 2025/26 the standard annual allowance is £60,000.
That growth is your "pension input amount". For a defined benefit scheme like the NHS Pension Scheme, it isn't the contributions you pay in. It's the increase in the capital value of your promised pension over the year, worked out using an HMRC formula. That's the part that surprises people: the figure can be far larger than anything that left your bank account.
If your total pension input amount across all your schemes is more than your available annual allowance, the excess is added to your taxable income and taxed at your marginal rate. That's the annual allowance charge.
Two things make this an NHS-specific headache. First, NHS benefits are defined by your salary and service, so you can't simply dial down your "contributions" to stay under the line the way someone in a workplace defined contribution scheme can. Second, NHS doctors and dentists often have both a high salary and a fast-growing pension, which is exactly the combination the rules target.
How is NHS pension growth measured?
Your pension growth, or pension input amount, is calculated by NHS Pensions and reported to you on an annual allowance pension savings statement.
In broad terms, the scheme takes the value of your pension at the start of the year, increases the opening figure in line with inflation, then compares it with the value at the end of the year. The difference is your pension input amount for that year. A pay rise, a move up a pay scale, or extra pensionable work can all push growth up sharply in a single year.
You don't have to calculate this yourself. NHS Pensions issues a pension savings statement to members whose growth in a scheme exceeds the standard annual allowance, and you can request one if you think you may be close. You'll need that statement to complete the pension pages of your Self Assessment return, so it's worth chasing if it hasn't arrived.
If you have more than one type of NHS membership (for example the 1995/2008 scheme and the 2015 scheme), the growth in each is added together for the annual allowance test.
What is the tapered annual allowance?
For very high earners, the £60,000 allowance shrinks. This is the tapered annual allowance.
The taper bites only if you cross two separate income tests for 2025/26:
- Threshold income over £200,000. This is broadly your taxable income excluding your pension contributions (with some adjustments).
- Adjusted income over £260,000. This is broadly your taxable income with pension growth and contributions added back in.
You have to be over both. If your threshold income is £200,000 or less, you keep the full £60,000 allowance no matter how large your pension growth is. That threshold income gate is the single most useful thing to understand, because it's the lever clinicians can sometimes influence.
Once you're caught, your £60,000 allowance is reduced by £1 for every £2 of adjusted income above £260,000. The reduction is capped, so the allowance can't fall below a minimum tapered annual allowance of £10,000 for 2025/26. That floor is reached once adjusted income hits £360,000.
| Adjusted income (2025/26) | Reduction | Tapered annual allowance |
|---|---|---|
| £260,000 or below | £0 | £60,000 |
| £280,000 | £10,000 | £50,000 |
| £300,000 | £20,000 | £40,000 |
| £340,000 | £40,000 | £20,000 |
| £360,000 or above | £50,000 (capped) | £10,000 |
Worked example: a consultant caught by the taper
Illustrative example. Meet Dr Anya Okafor, a hospital consultant. She is not a real client, and the figures are chosen to show the mechanics for 2025/26.
Her adjusted income for the year is £290,000, and her threshold income is £210,000. Both are over their respective limits, so the taper applies.
- Adjusted income over £260,000: £290,000 - £260,000 = £30,000.
- Reduction to her allowance: £30,000 / 2 = £15,000.
- Her tapered annual allowance: £60,000 - £15,000 = £45,000.
NHS Pensions reports her pension input amount for the year as £55,000.
- Excess over her tapered allowance: £55,000 - £45,000 = £10,000 (assuming no unused allowance to carry forward).
That £10,000 is added to her income and taxed at her marginal rate. As an additional-rate taxpayer at 45%, her annual allowance charge is £4,500.
Two takeaways. First, she pays a real charge even though the £55,000 of "growth" never appeared as cash. Second, because the charge is more than £2,000 and her growth in a single NHS scheme is over the standard annual allowance, she may be able to ask the scheme to pay it for her (see below).
Can carry forward reduce the charge?
Often, yes. You can carry forward any annual allowance you didn't use from the previous three tax years and add it to the current year's allowance.
So before assuming a charge is due, check whether your pension grew by less than your allowance in any of the prior three years. Unused amounts from those years can soak up this year's excess. You have to use the current year's allowance first, then the oldest available carried-forward year next.
For a tapered year, you carry forward whatever allowance was unused in each of those earlier years (which may itself have been tapered). The arithmetic gets messy quickly, especially across the 1995/2008 and 2015 schemes, so this is a point where a careful calculation really pays off. Our tax advisory team regularly rebuilds these figures for clinicians who've been told they owe a charge and don't.
How do you pay an annual allowance charge?
If a charge is due, you report it through the pension savings section of your Self Assessment tax return. There are then two ways to settle it.
Pay it yourself. The charge forms part of your Self Assessment bill, due by 31 January after the end of the tax year.
Ask the NHS scheme to pay it (Scheme Pays). Instead of finding the cash, you can ask NHS Pensions to pay some or all of the charge in exchange for a permanent reduction to your eventual pension. There are two versions:
- Mandatory Scheme Pays. The scheme must pay if your pension input amount in a single NHS scheme exceeds the standard annual allowance, your annual allowance charge for the year is more than £2,000, and you elect by the deadline.
- Voluntary Scheme Pays. This can cover charges that don't meet the mandatory test, for example where the charge arises only after combining two NHS schemes or because the taper reduced your allowance below £60,000.
You make the election using NHS Pensions' Scheme Pays election form (SPE2). The deadline for both routes is broadly 31 July in the year after the tax year of the charge. Importantly, with voluntary Scheme Pays you stay responsible for the charge and any interest if HMRC isn't paid by its 31 January deadline, so don't leave it late. And once a Scheme Pays election is accepted, you can't change your mind and pay it yourself instead.
Scheme Pays solves a cash-flow problem, but it isn't free money. It reduces your pension for life, so whether it beats paying out of taxed income is a judgement call worth modelling.
What should clinicians do now? A decision checklist
Work through these in order:
- Find your pension savings statement. No statement and you think you might be close? Request one from NHS Pensions. You can't do the maths without your pension input amount.
- Check the threshold income gate. If your threshold income is £200,000 or less for 2025/26, the taper can't apply and you keep the full £60,000 allowance.
- If both income tests are crossed, work out your tapered allowance using the £1-for-£2 reduction, with a £10,000 floor.
- Apply carry forward. Add any unused allowance from the previous three years before assuming a charge is due.
- If a charge remains, decide how to pay it. Compare paying from taxed income against Scheme Pays, and check whether you meet the mandatory test.
- Diarise the deadlines. Self Assessment payment by 31 January; Scheme Pays election by 31 July.

Frequently asked questions
Does everyone in the NHS pension pay an annual allowance charge?
No. Most members never breach the £60,000 standard allowance for 2025/26. The charge tends to hit higher earners and those who had a big jump in pensionable pay in a single year, which is why consultants, senior GPs and high-earning dentists are caught more often.
What is the difference between threshold income and adjusted income?
Threshold income is broadly your taxable income excluding pension contributions. Adjusted income broadly adds your pension growth and contributions back in. For 2025/26 the taper applies only if your threshold income is over £200,000 and your adjusted income is over £260,000. You must be over both.
How much can my annual allowance be tapered down to?
For 2025/26 the lowest your tapered annual allowance can fall is £10,000. That minimum is reached once your adjusted income is £360,000 or more.
Can I use carry forward against an NHS annual allowance charge?
Yes. You can carry forward unused annual allowance from the previous three tax years and add it to the current year. You use the current year's allowance first, then the oldest available year. This often reduces or removes a charge, so always check before assuming one is due.
Should I use Scheme Pays or pay the charge myself?
It depends. Scheme Pays helps your cash flow but permanently reduces your future pension. Paying from income preserves your pension but needs the cash. Modelling both against your circumstances is the only way to know which is better, and a tax adviser can run the numbers for you.
When is the deadline to elect for Scheme Pays?
The deadline for both mandatory and voluntary Scheme Pays is broadly 31 July in the year after the tax year the charge relates to. The election is made on NHS Pensions' SPE2 form.
