How do I claim higher-rate pension tax relief?

If you pay 40% or 45% tax and contribute to a relief-at-source pension, your scheme only adds the basic 20% for you. The rest, another 20% or 25%, does not appear by itself; you have to claim it, through Self Assessment or by contacting HMRC. Plenty of higher earners never do, and quietly overpay for years.

Relief at source only gives you 20% automatically

Most personal pensions and workplace group personal pensions use "relief at source". You pay in from your take-home pay, and the pension provider then reclaims 20% basic-rate relief from HMRC and adds it to your pot. Pay in £800 and the provider tops it up to £1,000. That happens automatically and needs no action.

The problem is that the top-up is fixed at 20%, whatever rate you actually pay. A higher-rate taxpayer is entitled to 40% relief and an additional-rate taxpayer to 45%, but the extra 20 or 25 percentage points are not added to the pension. Instead, HMRC gives them back to you, as a reduction in your tax bill or a refund, but only once you tell them the contribution happened.

How to claim the extra 20% or 25%

There are two routes, depending on whether you already file:

• If you complete a Self Assessment return, put your gross personal pension contributions in the pensions section. HMRC extends your basic-rate band by the gross amount, and the extra relief comes through as a smaller bill or a refund.
• If you do not file, contact HMRC directly, by phone, online, or in writing, with the total you paid in. They can give the relief by adjusting your tax code for the current year or by refunding a past year.

Take a £1,000 gross contribution: you pay £800, the scheme adds £200, and £1,000 lands in your pot. As a 40% taxpayer you then reclaim a further £200 (20% of £1,000), so the £1,000 in your pension has really cost you £600. A 45% taxpayer reclaims £250, a net cost of £550. The pension contributions calculator shows the effect on your own income.

Backdate up to four years

Missed relief is not lost. You can claim back up to four tax years, so a claim made now can reach 2022/23. For someone who has been a higher-rate taxpayer paying into a personal pension for years without claiming, that catch-up can run to four figures.

You will need your contribution records for each year. Written claims for closed years are reconciled by HMRC and refunded, often by cheque or bank transfer. It is worth checking old payslips and pension statements before the oldest year drops out of reach, because once a year is more than four years past, the relief is gone for good.

Net pay and salary sacrifice already give full relief

Not every pension needs a claim, and claiming when you should not creates a mess. Two common arrangements already give your full-rate relief up front:

• Net pay schemes (common in larger workplace pensions) take your contribution from gross pay before income tax is worked out. A 40% taxpayer gets 40% relief immediately, so there is nothing extra to claim.
• Salary sacrifice means you formally give up salary in exchange for a pension contribution. You are never taxed on that pay at all, and you save National Insurance too, so again full relief is already given.

The rule of thumb: only relief-at-source contributions leave higher and additional-rate relief unclaimed. If your pension comes out before tax, you already have it. If you pay in from money that has already been taxed, check whether there is more to reclaim. Note that Scotland has different income tax bands, so Scottish taxpayers claim relief at their own intermediate, higher and top rates.

Common questions

How do I claim higher-rate tax relief on pension contributions?

Through Self Assessment, by entering your gross personal pension contributions in the pensions section, or by contacting HMRC directly if you do not file. This is only needed for relief-at-source pensions, where the provider adds just the basic 20% automatically.

How much extra relief can a higher-rate taxpayer claim?

Another 20 percentage points on top of the 20% the scheme adds, taking total relief to 40%. On a £1,000 gross contribution, that is a further £200 back, so the £1,000 in your pension costs you £600. Additional-rate (45%) taxpayers reclaim £250.

Can I backdate a higher-rate pension tax relief claim?

Yes, up to four tax years, so a claim now can reach back to 2022/23. You need contribution records for each year. Once a year is more than four years in the past, the unclaimed relief is lost.

Do I need to claim relief if my pension is salary sacrifice or net pay?

No. Salary sacrifice and net pay schemes take contributions from your pay before income tax, so you get your full 40% or 45% relief up front. Only relief-at-source pensions, funded from taxed pay, leave higher-rate relief to claim.
