Pension Tax Relief Explained

Pension contributions get tax relief at your marginal rate. Basic-rate taxpayers (20%) get £20 relief per £100 contributed. Higher-rate (40%) taxpayers get £40 relief, and additional-rate (45%) get £45. Most workplace pensions use relief at source, where 20% is added automatically and higher/additional-rate taxpayers claim the rest via Self Assessment.

How Pension Tax Relief Works

When you pay into a pension, the government adds tax relief to encourage saving for retirement. The amount of relief depends on your income tax band.1

Basic rate (20%)
£100 contribution costs £80
Higher rate (40%)
£100 contribution costs £60
Additional rate (45%)
£100 contribution costs £55

Relief at Source vs Net Pay

Most workplace pensions use one of two methods:2

  • Relief at source: You pay from net income, and the pension provider claims 20% from HMRC automatically. Higher/additional-rate taxpayers claim extra relief via Self Assessment.
  • Net pay: Contributions are deducted before tax, so you get relief automatically at your marginal rate.

Annual Allowance

The annual allowance for 2026-27 is £60,000. This is the maximum you can contribute across all pensions in a tax year while still getting tax relief.3

If you earn over £200,000, the allowance tapers down by £1 for every £2 above that threshold, to a minimum of £10,000 at £260,000+.
