Basic-rate relief is usually added to your pension automatically, but higher and additional-rate taxpayers must claim the extra themselves, through a self-assessment tax return or by contacting HMRC. A 40% taxpayer can reclaim a further 20% on personal contributions; a 45% taxpayer a further 25%.
The short answer
- Relief-at-source pensions add only 20% automatically, higher and additional-rate taxpayers must claim the rest.
- A 40% taxpayer reclaims a further 20%; a 45% taxpayer a further 25% of the gross contribution.
- Net-pay and salary-sacrifice schemes give full relief up front, so there is nothing extra to claim.
Pension tax relief is one of the biggest perks of saving into a pension, but for higher and additional-rate taxpayers, a large slice of it doesn’t arrive automatically. You have to claim it. Every year a substantial amount of relief goes unclaimed simply because savers assume the taxman has already sorted it. This answer explains exactly how the relief works and how to make sure you get all of yours.
The mechanics depend on how your contributions are paid. Get this right and a £10,000 pension contribution can cost a higher-rate taxpayer just £6,000. This is information, not personal advice, and investments can fall as well as rise.
Why higher earners have to claim
Most personal pensions and SIPPs use ‘relief at source’. You pay in from your after-tax income, and the pension provider automatically reclaims 20% basic-rate relief from HMRC and adds it to your pot. So an £8,000 contribution becomes £10,000 gross without you lifting a finger. The problem is that the provider only ever adds the basic 20%, even if you pay tax at 40% or 45%. The extra relief owed to higher earners has to be claimed back separately.
There is an important exception. If your workplace pension uses a ‘net pay’ arrangement or salary sacrifice, your contribution is taken before income tax is calculated, so you receive full relief at your marginal rate straight away and there is nothing extra to claim. If you are unsure which method your scheme uses, your payslip or provider can tell you, it changes whether you need to act at all.
This split explains a common and costly mistake. Many higher-rate taxpayers with a personal pension or a relief-at-source workplace scheme quietly lose thousands of pounds over the years, wrongly assuming that because ‘tax relief’ appeared on their statement, all of it was there. The 20% you can see is only part of the story if you pay tax at 40% or 45%: the balance sits with HMRC until you ask for it.
How much extra you can claim
What you can reclaim on a £10,000 gross pension contribution (2026/27)
| Your tax band | Relief at source | Extra you claim | Effective cost |
|---|---|---|---|
| Basic rate (20%) | £2,000 | £0 | £8,000 |
| Higher rate (40%) | £2,000 | £2,000 | £6,000 |
| Additional rate (45%) | £2,000 | £2,500 | £5,500 |
The extra relief is worth having: a higher-rate taxpayer effectively gets a £4,000 top-up on a £6,000 outlay. Scottish taxpayers have different bands and rates, so the amounts you can reclaim differ north of the border, but the principle is the same. The relief works by extending your basic-rate band, so it only benefits you to the extent you actually pay tax at the higher rate. Our guide to how much you can pay into a pension tax-free explains the allowances that sit alongside this.
It is worth being clear about what the relief is not. It does not mean the government simply hands cash into your pot, the extra relief usually reduces the income tax you owe elsewhere, or is repaid to you directly, rather than being added straight into the pension. That still leaves you better off by the same amount, but it is why some savers reinvest their refund to compound the benefit rather than spending it.
How to actually claim it
There are two routes to reclaiming the extra, and which applies depends on whether you already complete a tax return. Neither is difficult, but both put the responsibility firmly on you rather than your pension provider.
- 1
Through self-assessment
If you already file a tax return, enter your gross personal pension contributions in the pensions section; HMRC adjusts your bill or refunds you.
- 2
By contacting HMRC directly
If you don’t file a return, call or write to HMRC with your contribution figures: they can refund you or adjust your tax code.
- 3
Keep your provider statements
Your annual pension statement shows the gross figure you need. Keep these safe as evidence of what you paid in.
- 4
Backdate if you’ve missed years
You can usually reclaim up to four tax years of unclaimed higher-rate relief, so it is worth checking past contributions.
Don’t leave money on the table
Higher-rate relief is not lost if you forget in the current year, but the four-year backdating window does eventually close. If you have been a higher earner paying into a relief-at-source pension for years without ever claiming, you may be owed a meaningful refund.
When it pays to get help
For most people the claim is straightforward. It gets trickier if your income crosses allowance thresholds, for example the withdrawal of the personal allowance above £100,000, or the tapered annual allowance for very high earners. In those cases a pension contribution can reclaim far more than 40%, and getting the sums right matters.

In summary
- Relief-at-source pensions add only 20% automatically, higher and additional-rate taxpayers must claim the rest.
- A 40% taxpayer reclaims a further 20%; a 45% taxpayer a further 25% of the gross contribution.
- Net-pay and salary-sacrifice schemes give full relief up front, so there is nothing extra to claim.
- Claim via self-assessment or by contacting HMRC, and you can usually backdate up to four tax years.
- Around the £100,000 income threshold the relief can be worth much more, take advice if this affects you.
