Pension tax relief calculator for higher rate taxpayers

If you earn over £50,270 (£43,663 in Scotland) and pay into a Relief at Source pension, your provider only claims 20%. This calculator shows the extra relief HMRC owes you for the 4 tax years you can still claim - worked out the way HMRC does, not with a flat percentage.

  • ✓ Relief limited to the income actually taxed above basic rate
  • ✓ £100k-£125,140 personal allowance taper (effective 60%)
  • ✓ Additional rate at £125,140 (£150,000 before 2023/24)
  • ✓ Scottish bands

Then, if you want it done properly: our £99 claim pack produces the correctly worded HMRC letter, the year-by-year calculation and the evidence checklist HMRC now requires - with a money-back guarantee.

Worked examples for 2025/26

The same contribution rate is worth very different amounts depending on how far above the threshold you are. Contribution figures are gross (including the 20% added at source).

Note the £55,000 row: only £4,730 of income sits above £50,270, so the relief is smaller than a flat 20% of the contribution would suggest. This is the single most common mistake in DIY claims, and the reason HMRC reduces them.

Calculator questions

How does the calculator work out my relief?
It uses HMRC's method: your basic rate band is extended by your gross pension contribution, so income that was taxed at 40% (or 45%) is taxed at 20% instead. Only the part of the contribution that falls above the higher-rate threshold attracts extra relief, and contributions also restore personal allowance lost between £100,000 and £125,140. The estimate assumes the same salary and contribution rate in each of the 4 claimable years (2022/23, 2023/24, 2024/25, 2025/26).
What is a "gross" contribution?
The amount that lands in your pension including the 20% your provider adds. If £80 leaves your pay, the gross contribution is £100. Payslips usually show the net figure; pension statements often show both.
Which pensions qualify?
Relief at Source schemes: NEST, The People's Pension, personal pensions and SIPPs, and most group personal pensions from Aviva, Scottish Widows, Standard Life, Royal London, Legal & General, Aegon and Fidelity. Net Pay schemes (NOW: Pensions, Smart Pension by default, Cushon, NHS, Teachers', LGPS, Civil Service) and salary sacrifice already give full relief, so there is nothing to claim.
How far back can I claim?
Four complete tax years. The oldest year you can still claim is 2022/23, until 5 April 2027. Each April the oldest year drops off.
Does the calculator handle Scottish tax rates?
Yes - tick "I pay Scottish income tax". Scottish higher rate starts at £43,663, and the extra relief is 1%, 22%, 25% or 28% depending on your band.
Is the estimate what HMRC will pay?
It is a close estimate based on the figures you enter. HMRC does the final calculation using your P60 and pension statements, which is why the claim pack asks you to confirm the exact figures for each year before the letter is produced.
