Pension tax relief is the government’s biggest incentive to save for retirement — and one of the most misunderstood parts of the tax system. In simple terms, the government adds back the Income Tax you paid on the money you put into a pension. This guide explains how relief works, how much you can put in, the £60,000 annual allowance, the taper for high earners, and the limits on tax-free cash. It does not tell you whether to contribute to a pension — that is a personal decision, and you should get regulated advice if you are unsure.

Pension tax relief in one paragraph

You get tax relief on pension contributions at your marginal Income Tax rate — 20%, 40% or 45%. A basic-rate taxpayer who pays £80 into a personal pension gets £20 added by the provider, so £100 goes into the pot. The annual allowance is £60,000 a year, and relief is limited to 100% of your earnings. Unused allowance can be carried forward for up to 3 years.

How relief works

There are two main ways relief is given. In a personal pension, relief at source applies: you pay in £80, your provider claims £20 from HMRC and adds it to your pot, so £100 goes in. In a workplace pension paid through net pay, your contribution comes out of your pay before tax is calculated, so you never pay tax on it in the first place. The result is the same: the money goes in tax-free.

Higher-rate and additional-rate taxpayers get more relief, but not automatically. If you pay 40% tax, you can claim an extra 20% on the part of your contribution that corresponds to income taxed at 40% — usually through Self Assessment. If you pay 45%, you can claim an extra 25%. Many higher-rate taxpayers miss this extra relief because they never claim it.

The annual allowance

The annual allowance is the total that can be paid into your pensions in a tax year and still get tax relief. For 2026/27 it is £60,000, and it covers everything: your contributions, your employer’s contributions, and the tax relief added on top. If the total paid in is more than the allowance, the excess is charged to tax at your marginal rate.

There is a second limit as well: tax relief on your own contributions is limited to 100% of your relevant UK earnings in the year. If you earn £30,000, you cannot get relief on more than £30,000 of personal contributions, even though the annual allowance is £60,000. If you have no earnings, you can still get relief on up to £2,880 a year that you pay in (£3,600 gross).

Carry forward

If you do not use the full annual allowance in a year, you can carry the unused amount forward for up to 3 tax years — as long as you were a member of a registered pension scheme in those years. So if you used only £20,000 of the allowance in each of the last three years, you could have up to £120,000 of unused allowance to use this year, on top of this year’s £60,000.

Carry forward is useful when your income jumps — a bonus year, a sale, or a late-career pay rise. But the 100%-of-earnings limit still applies to your own contributions, so carry forward helps most when the extra money comes from an employer, or when you have high earnings in the current year.

The tapered allowance for high earners

High earners get a smaller allowance. If your threshold income is over £200,000 and your adjusted income is over £260,000, your annual allowance falls by £1 for every £2 of adjusted income over £260,000, down to a minimum of £10,000. At an adjusted income of £360,000 or more, the allowance is £10,000.

The taper is complicated, and it catches people by surprise — especially those whose income includes bonuses or employer pension contributions, which count towards adjusted income. If your income is anywhere near these levels, check the GOV.UK guidance on the annual allowance, and consider professional advice before making large contributions.

Taking money out, and the lump sum allowance

You can usually take up to 25% of your pension as tax-free cash, up to a maximum — the lump sum allowance — of £268,275. The rest is taxed as income when you take it. The old Lifetime Allowance, which used to cap the total size of your pension, was abolished from 6 April 2024 and replaced by the lump sum allowance and a lump sum and death benefit allowance of £1,073,100.

If you take taxable income flexibly from a defined contribution pension, a different limit applies to future contributions: the money purchase annual allowance, which is £10,000 for 2026/27. Once it applies, it replaces the £60,000 allowance for defined contribution pensions. That is a strong reason to understand the rules before you start drawing a pension flexibly.
