What Is Pension Tax Relief?
Pension tax relief is a government incentive that tops up your pension contributions. When you pay into a pension, the government adds money on top based on the income tax you pay. For every £80 a basic-rate taxpayer puts in, the government adds £20 – effectively giving you £100 in your pension for just £80 out of pocket.
Tax relief is available on pension contributions up to 100% of your annual earnings or £60,000 (whichever is lower). It applies to personal pensions, workplace pensions, and Self-Invested Personal Pensions (SIPPs).
How Tax Relief Works at Each Rate
| Tax Band | Rate | You Pay | Gov Adds | Total in Pension |
|---|---|---|---|---|
| Basic rate | 20% | £80 | £20 | £100 |
| Higher rate | 40% | £60 | £40 | £100 |
| Additional rate | 45% | £55 | £45 | £100 |
| Scottish higher | 42% | £58 | £42 | £100 |
Relief at Source vs Net Pay
There are two methods your pension scheme may use to apply tax relief:
Relief at Source
Your pension provider claims back 20% basic-rate tax relief from HMRC and adds it to your pension automatically. If you are a higher or additional-rate taxpayer, you must claim the extra relief through Self Assessment.
Net Pay Arrangement
Your contributions are taken from your salary before income tax is calculated, so you get the full tax relief immediately through your payroll. This is common in workplace pensions. The downside is that if you earn below the personal allowance, you miss out on the 20% relief.
Salary Sacrifice
With salary sacrifice, you agree to a lower salary in exchange for higher employer pension contributions. The advantage is that you also save on National Insurance contributions (currently 8% for employees), which can make salary sacrifice more tax-efficient than standard pension contributions.
How to Claim Higher-Rate Tax Relief
If your pension uses relief at source and you pay 40% or 45% tax, you can claim the difference through:
- Self Assessment tax return – enter your total pension contributions in the relevant box
- Calling HMRC – if you do not normally file a tax return, you can call HMRC to adjust your tax code
- Writing to HMRC – you can write to your tax office with details of your contributions
You can claim relief for the current tax year and the previous four tax years, so check whether you have missed any claims.
Annual Allowance and Limits
The annual allowance for pension contributions is £60,000 for the 2025/26 and 2026/27 tax years. This includes both your contributions and any employer contributions. If you exceed this limit, you face a tax charge on the excess at your marginal rate.
High earners (adjusted income over £260,000) face a tapered annual allowance that reduces to a minimum of £10,000. If you have accessed your pension flexibly, the Money Purchase Annual Allowance (MPAA) of £10,000 applies.
