How pension tax relief works
What you'll learn
Understand pension tax relief and why it is often called free money on contributions.
Tax relief is the government adding money to your pension. When you pay in, some of the income tax you would otherwise have handed over goes into your pot instead. That is why people call it free money: it costs you less than the amount that lands in the pension.
The cost depends on your tax band. Relief is broadly given at your highest rate of income tax, so the more tax you pay, the more relief the same contribution attracts.
| To get £100 in your pension | Roughly costs you |
|---|---|
| Basic-rate taxpayer | About £80 |
| Higher-rate taxpayer | About £60 |
| Additional-rate taxpayer | Even less |

How you get it
There are two common methods. With relief at source, the provider claims basic-rate relief and adds it for you, and higher-rate payers claim the rest through their tax return. With net pay or salary sacrifice, the contribution comes out before tax is calculated, so the relief is built in automatically. Your payslip or scheme tells you which applies.
The catch
Relief is not unlimited. There is an annual allowance that caps how much you can pay in with relief each year, and it can change. Before making a large one-off contribution, check the current allowance.

Key takeaways
- Tax relief means the government tops up your pension contributions.
- It is broadly given at your highest income tax rate, so higher earners get more on the same amount.
- That makes a pound in a pension cheaper than a pound spent elsewhere.
- There is an annual cap on relieved contributions; check the current figure on gov.uk.
Illustrative only, not a forecast. Figures assume basic-rate relief at 20% and higher-rate relief at 40%, which are the rates in common use; rates and rules can change, so check the current position on gov.uk. Your actual cost depends on your tax band.
Frequently asked questions
Why is tax relief called free money?
Because the government tops up your contribution. To get a set amount into your pension, you pay in less than that amount; the relief makes up the difference.
Do higher earners get more relief?
In broad terms, relief is given at your highest rate of income tax, so a higher-rate payer gets more relief on the same contribution than a basic-rate payer. The exact mechanics and rates can change, so check gov.uk.
Is there a limit on relief?
Yes. The amount you can pay in with tax relief each year is capped, and the cap can change. Always check the current annual allowance on gov.uk before making large contributions.
