How much higher-rate pension relief can I claim?

Higher-rate taxpayers (40%) can claim an extra 20% of their gross contributions back from HMRC. Additional-rate taxpayers (45%) can claim 25%. So a £10,000 gross contribution by a higher-rate taxpayer entitles £2,000 of additional relief — on top of the £2,000 basic-rate relief already added at source by the pension provider.

Can I backdate higher-rate pension tax relief claims?

Yes — up to four tax years back. As of May 2026, you can claim for 2022/23, 2023/24, 2024/25 and 2025/26. The amount of relief is calculated on your tax position in each individual year. Most people who do this for the first time receive £2,000-£8,000 in backdated refunds plus interest.

Do I need to claim relief on my workplace auto-enrolment pension?

It depends on the scheme type. Most workplace pensions use either net pay (full relief automatic) or salary sacrifice (full relief automatic). Some use relief-at-source — then you do need to claim. Check with your provider or HR. NEST, Smart Pension and The People's Pension are usually relief-at-source.

7-minute read

For a personal pension or SIPP, basic-rate relief is added at source. Higher-rate taxpayers must claim the extra 20% themselves. Additional-rate taxpayers claim 25%. Scottish higher-rate taxpayers claim 22%. There are three routes: (1) via Self Assessment if you already file, (2) via written claim to HMRC if you don't, (3) via a tax code adjustment for ongoing contributions. You can backdate claims four tax years (so in May 2026 you can still claim for 2021/22 onwards). Workplace auto-enrolment is usually different (salary sacrifice or net pay — full relief already given).

Which pensions need a manual claim?

Pension type	How relief is given	Manual claim needed?
Personal pension / SIPP	Basic-rate (25% gross-up) at source. Higher-rate manually.	YES (if higher/additional rate)
Workplace pension (net pay arrangement)	Full relief at source via payroll — gross deduction.	No — automatic
Workplace pension (relief at source)	Basic-rate at source. Higher-rate manually.	YES (if higher/additional rate)
Salary sacrifice scheme	Full relief automatic (no income tax, no NI on sacrificed amount).	No — automatic
Old "stakeholder" pensions	Basic-rate at source.	YES (if higher/additional rate)

How to tell which arrangement appliesCheck with your pension provider. Net pay schemes show the deduction taken from your payslip BEFORE tax (e.g. £400 from a £4,000 monthly gross → tax calculated on £3,600). Relief-at-source schemes deduct from AFTER tax pay — provider then claims back 25% gross-up. Salary sacrifice reduces your gross salary in your contract.

The 2026/27 maths — how much relief you can claim

Your highest tax rate	Relief already given	Total entitled relief	Manual claim worth
20% basic rate	20% (full)	20%	£0 (no extra)
40% higher rate	20% (at source)	40%	20% of gross contribution
45% additional rate	20% (at source)	45%	25% of gross contribution
60% trap (£100k-£125k)	20% (at source)	~60%	~40% of gross contribution
Scottish 21% intermediate	20% (at source)	21%	1% of gross contribution
Scottish 42% higher	20% (at source)	42%	22% of gross contribution
Scottish 45% advanced	20% (at source)	45%	25% of gross contribution
Scottish 48% top	20% (at source)	48%	28% of gross contribution

Worked example: £80,000 earner, £10,000 gross pension contribution

You pay £8,000 from your bank account
Provider adds £2,000 basic-rate relief → £10,000 in pension
HMRC owes you 20% × £10,000 = £2,000 more
Net cost of £10,000 pension contribution: £8,000 − £2,000 refund = £6,000
Effective tax saving: 40%

Worked example: £110,000 earner (in 60% trap), £20,000 gross contribution

You pay £16,000 from your bank account
Provider adds £4,000 basic-rate relief → £20,000 in pension
You're in the £100k-£125k PA-taper band. Each £1 of pension contribution restores £0.50 of PA, saving you 40% on that £0.50.
HMRC owes you 20% × £20,000 (standard higher-rate) + 20% × £20,000 (restored PA = £10k × 40%) = £4,000 + £4,000 = £8,000 more
Net cost of £20,000 pension contribution: £16,000 − £8,000 = £8,000
Effective tax saving: 60%

Route 1: Self Assessment

If you already file Self Assessment, this is the easiest route.

Where to put pension contributions on the SA100SA100 page 4, box "Payments to registered pension schemes (also known as PPR) where basic rate tax relief will be claimed by your pension provider": enter the NET amount you contributed (before the gross-up). E.g. paid £8,000, enter £8,000.

HMRC calculates the reliefHMRC automatically calculates the extra higher-rate relief based on your declared income. You don't need to compute it — just enter the contribution. The relief is netted against your tax bill (reduces the bill or increases the refund).

Backdate via earlier years' returnsYou can amend a Self Assessment return for up to 12 months after the original filing deadline. So in May 2026 you could amend 2024/25 (filed by Jan 2026, amendable until Jan 2027). For older years, use a written claim.

Route 2: Written claim (no Self Assessment)

If you don't normally file SA, write to HMRC.

[Your full address] [Postcode] [Date] PAYE and Self Assessment HM Revenue and Customs BX9 1AS Dear HMRC, Re: Claim for higher-rate pension tax relief National Insurance number: [QQ 12 34 56 A] Tax years: [2022/23, 2023/24, 2024/25, 2025/26] I am writing to claim higher-rate tax relief on personal pension contributions made in the tax years listed above. The contributions were made to [pension provider name(s)] and basic-rate relief was already added by the provider. The contributions in each year (gross of basic-rate relief): • 2022/23: £[X] gross / £[Y] net paid by me • 2023/24: £[X] gross / £[Y] net paid by me • 2024/25: £[X] gross / £[Y] net paid by me • 2025/26: £[X] gross / £[Y] net paid by me My taxable income (employment + other) in each year was: • 2022/23: £[X] • 2023/24: £[X] • 2024/25: £[X] • 2025/26: £[X] I enclose copies of: • Pension contribution statements from [provider] • P60 for each tax year • [Any other evidence] Please calculate and pay the higher-rate relief due. My bank details for payment: Account name: [Name on account] Sort code: [XX-XX-XX] Account number: [XXXXXXXX] Yours faithfully, [Signature] [Full name printed] [Daytime telephone number]

Route 3: Tax code adjustment (ongoing)

If you make regular ongoing contributions to a personal pension, ask HMRC to update your tax code to give you the relief throughout the year (rather than a lump-sum refund later).

How to requestCall HMRC on 0300 200 3300 or write/online via Personal Tax Account. Tell them you make regular contributions of £X per month to [provider] and ask them to adjust your tax code to provide higher-rate relief. They'll add roughly £2,500 (or whatever your annual gross contribution × 0.5) to your tax-free allowance — code goes from 1257L → 1500L or similar.

Watch for over-relief.If you stop contributing partway through the year but the tax code still gives you relief, you'll have an underpayment at year-end. Adjust the code whenever contribution levels change.

Backdate four years — the windfall opportunity

Tax relief can be claimed up to four tax years back. As of May 2026, you can claim for:

2022/23 (return amendments closed Jan 2024, written claim only)
2023/24 (amendable until Jan 2026 — closed, written claim only)
2024/25 (amendable until Jan 2027 — SA route possible)
2025/26 (filing this year — SA route)

Worked example: 4-year backdate windfall

Mark earns £75,000, makes £8,000 net contributions (£10,000 gross) every year to a SIPP. Never claimed higher-rate relief.

4 years × £2,000 = £8,000 refund (plus interest at HMRC's prevailing rate, ~3-4%)
Written claim with P60s and SIPP statements
Typically settled in 30-60 days

Common mistakes

Mistake 1: Net pay vs relief-at-source confusion.If you're in a net pay workplace scheme (most NHS, Civil Service, some big employers), you already get full relief — don't claim again. If you're in relief-at-source (most private sector, NEST, Smart Pension), claim the extra.

Mistake 2: Salary sacrifice claim attempts.Salary sacrifice contributions are pre-tax — no need to claim anything. Some people mistakenly claim and get correctness notices from HMRC.

Mistake 3: Claiming gross when net is requested.SA100 asks for the NET amount you paid. Some filers enter gross (after the 25% gross-up). This effectively double-counts.

Mistake 4: Forgetting the Annual Allowance cap.The Annual Allowance is £60,000 (2026/27) but tapers to £10,000 floor above £260,000 adjusted income. Contributions above your AA face an Annual Allowance Charge — relief is given but partly clawed back.

Mistake 5: Not realising you qualify.If your income tipped into higher-rate just for one year (e.g. bonus year), you can still claim higher-rate relief for that year. Many one-off higher-rate years go unclaimed.
