Pension Tax Relief Calculator
See how much tax relief you get on UK pension contributions, and how much higher-rate relief to claim back.
About the Pension Tax Relief Calculator
Pension contributions get income tax relief at your highest rate. Under relief at source (personal pensions, SIPPs and many workplace schemes), you pay 80% and your provider claims 20% from HMRC; higher and additional-rate taxpayers claim the extra through Self Assessment, which many people miss. Under net pay arrangements, contributions come off your pay before tax, so full relief is automatic. Contributions over £100,000 of income can also restore some of the Personal Allowance, giving very high effective relief.
The formula
Total relief = tax on income − tax on (income − gross contribution)
Worked example
Example: Total tax relief = £4,400.00
- Inputs: Your taxable income (before the contribution): £77,000; Amount you pay in: £8,800; Scheme type: Relief at source (personal / SIPP); Scottish taxpayer: No.
- Formula: Total relief = tax on income − tax on (income − gross contribution)
- Result: Total tax relief = £4,400.00
Questions people ask
