Assumptions used
- The calculation compares Income Tax before and after an equivalent gross pension deduction, including Personal Allowance taper restoration.
- For relief at source, 20% of the gross contribution is treated as provider relief and only the balance is shown as a possible claim.
- Scottish starter, basic, intermediate, higher, advanced and top rates are used for the selected year.
- Savings income, dividends, Gift Aid, Marriage Allowance, Blind Person’s Allowance and other deductions are excluded.
- Annual allowance, tapering, carry-forward, relevant-earnings eligibility and the money purchase annual allowance are not calculated.
This is a reclaim diagnostic, not a tax return. Claim only relief you are entitled to and can evidence; HMRC’s calculation governs.
Common questions
Pension tax-relief reclaim FAQs
When do I need to claim extra pension tax relief?
A claim is commonly needed when a relief-at-source pension provider adds basic 20% relief but you paid Income Tax above 20% on some of the contribution. Net pay and salary sacrifice normally deliver Income Tax relief automatically, so claiming again could duplicate relief.
How do I know whether my pension uses relief at source or net pay?
Check a payslip, pension statement or ask payroll or the provider. With relief at source, a payment of £80 is normally grossed up to £100 in the pension. Under net pay, the gross contribution is deducted from pay before Income Tax. Salary sacrifice reduces contractual cash salary in exchange for an employer pension contribution.
How much can a higher-rate taxpayer reclaim?
For England, Wales and Northern Ireland, relief-at-source contributions can create another 20% on the part supported by income taxed at 40%, and another 25% on the part taxed at 45%. The calculator also estimates the effect of restoring tapered Personal Allowance above £100,000.
What can Scottish taxpayers reclaim?
HMRC states that relief-at-source contributors can claim another 1% on income taxed at 21%, 22% at 42%, 25% at 45% and 28% at 48%, limited to the contribution supported by income in each band. A 19% starter-rate taxpayer does not have to repay the provider’s 20% relief.
Can I claim pension tax relief for previous years?
The general Income Tax claim limit is four years after the end of the relevant tax year. The normal deadline for amending a Self Assessment return can be shorter, after which an overpayment-relief or other HMRC route may be required. The checker shows general deadlines, but HMRC should confirm the route.
How do I claim if I do not file Self Assessment?
HMRC has an online service for a current-year pension tax-relief claim through a tax-code adjustment. Its guidance says the online service is only for the current tax year. Earlier years and people unable to use the service should follow HMRC’s contact or postal route.
What evidence does HMRC require?
HMRC’s current service asks for a National Insurance number, pension type and provider, net contributions for each year and a workplace payroll reference. It also requires proof such as a provider statement, letter or payslip showing the contributions and how relief was handled.
Does the estimate check the pension annual allowance?
No. The standard annual allowance is £60,000 for 2026/27, but tapering, employer contributions, defined-benefit accrual, carry-forward and the £10,000 money purchase annual allowance can change the position. Tax relief is also limited by relevant UK earnings.
