Pension tax relief: how it works and how to claim it

Pension tax relief is the government's contribution to your retirement savings. When you pay into a pension, the government adds money to your pot or reduces your tax bill, so that saving for retirement costs you less than the amount invested. For a basic-rate taxpayer, a £100 contribution costs £80, because the government adds £20¹. For a higher-rate taxpayer who claims the extra relief, the same £100 contribution costs £60².

How that relief reaches you depends on how your pension is set up. Some schemes add it automatically through payroll, others have the provider claim it from HMRC, and higher and additional-rate taxpayers always have to claim their extra share themselves. This page explains each route, the limits on how much relief you can get, the special rule for people with little or no earnings, and what to do if your relief has gone missing.

How pension tax relief works: relief at your highest rate of income tax

The principle behind pension tax relief is simple: contributions to a pension receive income tax relief at the saver's marginal rate of income tax, the highest rate they pay⁸. The government wants to encourage retirement saving, so it gives you a contribution in the form of tax relief, which either reduces your tax bill or increases your pension fund⁹.

In practice, this means the money going into your pension is treated as if it had never been taxed at your highest rate. Tax relief is based on the highest rate of income tax you pay, and it boosts your pension contributions by at least 20%³. Someone paying tax at 40% gets relief at 40%, and someone paying at 45% gets relief at 45%, provided they claim the portion above the basic rate.

The relief is not a single payment arriving in your bank account. It arrives in two possible ways: added to your pension pot by the provider, or taken off your tax bill through your pay or tax return. Which of these happens depends on whether your scheme operates "relief at source" or a "net pay arrangement", covered later on this page. What is common to both is the end result: the full contribution ends up in your pension, and the net cost to you reflects the tax you would otherwise have paid on that money.

You usually get tax relief on money you pay into a pension, though the exact amount depends on your circumstances and how much you earn². The rules also change at the top and bottom of the income scale: there is a ceiling on how much can attract relief each year, and a floor that protects people with very low earnings from losing out entirely.

Relief rates: 20%, 40% and 45%

In England, Wales and Northern Ireland, income tax has three main rates, and pension tax relief follows them. Basic-rate taxpayers get relief at 20%, higher-rate taxpayers at 40%, and additional-rate taxpayers at 45%⁴. Scotland has its own income tax bands, so Scottish taxpayers get different amounts, covered in a later section.

The 20% basic-rate relief works as a straightforward top-up. Most personal pension providers claim tax relief automatically at a fixed rate of 20%, so a £100 contribution into your pension costs you £80². Another way of looking at it: for every £100 you save into a pension as a basic-rate taxpayer, the government adds £25 in tax relief¹⁰.

Above the basic rate, the extra relief comes as a reduction in your tax bill rather than a payment into your pot. If you pay income tax at 40%, a £100 pension contribution effectively costs £60 once you have claimed the extra relief⁶. Higher-rate taxpayers, those earning over £50,270, get an extra 20% on top of the basic rate, and additional-rate taxpayers get an extra 25%¹⁰. The claiming step matters: if a higher-rate taxpayer never claims, they keep only the automatic 20% and lose the rest.

Official statistics show how heavily this relief is weighted towards higher earners. In the 2023 to 2024 tax year, an estimated 56% of income tax relief on total pension contributions was relieved at the higher rate, 37% at the basic rate, and 7% at the additional rate⁷. That distribution is one reason pension tax relief is regularly debated in Parliament, but for an individual saver the practical point is simpler: the more tax you pay, the more each pound into your pension is worth, provided you claim it.

Who can get pension tax relief

The legal test is set out in the pension tax legislation: an individual who is an active member of a registered pension scheme is entitled to relief on contributions paid during a tax year if they are a relevant UK individual for that year¹². In everyday terms, you need to be a UK resident for tax purposes and under 75 to get tax relief on pension contributions⁶.

Within that framework, the rules are deliberately wide:

• Workers get relief on contributions up to 100% of their earnings, as long as they are under 75¹³.
• People in workplace pensions may also get tax relief from the government on top of what they and their employer pay in¹⁴.
• People who are not automatically enrolled, including those earning £6,240 or less, those earning between £6,240 and £10,000, and people at or over State Pension age, might still get some tax relief, and should check with whoever runs their pension scheme¹⁵.
• Non-taxpayers can still get tax relief on their own or someone else's contributions, up to a certain limit¹⁶.

You do not need to be retired from work to get your pension benefits, and equally you do not need to be in work to build up a pot: the relief rules are tied to residence, age and earnings rather than employment status¹⁷. The conditions that matter are that you do not pay in more than you earn, that all payments in are less than the annual allowance, and that you are under 75².

The type of pension also matters less than people assume. Relief is available whether you save through a workplace pension, a personal pension or a stakeholder pension, though the mechanics of how the relief is delivered differ between schemes, which is the subject of the next section.

The annual allowance: up to £60,000 or 100% of your earnings

There is no limit on the amount you can pay into a pension, but there is a limit on the amount that earns tax relief. Each year you receive tax relief on pension contributions of up to 100% of your UK earnings, salary and other earned income¹⁸. On top of that earnings test sits the annual allowance: the maximum contribution you can earn tax relief on in a year is £60,000⁵. The official rates and allowances tables confirm the annual allowance limit at £60,000¹⁹.

The two limits work together, and the lower of them is the one that binds:

The annual allowance is £60,000 a year, but tax relief also stops at 100% of your earnings, whichever is lower. So a person whose earnings are below £60,000 can only get relief on contributions up to what they earned that year, while a person earning more than £60,000 is capped by the allowance rather than their salary. You can contribute up to £60,000 a year, or your total earnings if lower, and still receive tax relief²⁰.

Two things soften the earnings limit in practice. First, contributions above the relief limit do not vanish: they can still go into the pension, but no relief is added and the annual allowance tax charge rules can apply. Second, unused allowance from earlier years can in some cases be carried forward, which is covered on the carry forward page. The full detail of the allowance itself, including how it is measured across all your pensions and what happens when you flexibly access a pot, is on the annual allowance page.

Relief at source or net pay: how your pension gets the relief

Pension schemes deliver tax relief in one of two ways, and which one yours uses determines whether you see the relief in your pot or in your payslip. You can tell if it is relief at source if the pension provider has to claim the tax relief from HMRC²¹.

Relief at source is used by personal pensions, stakeholder pensions and many workplace schemes. Your employer takes your pension contribution from your pay after deducting tax and National Insurance contributions. Your pension scheme provider then claims the tax back from the government at the basic rate of 20% and adds it to your pot¹³. In effect, the provider takes 80% from your salary and claims the other 20% from the government²². If you do not pay income tax because you are on a low income, you automatically get tax relief under this arrangement¹³.

Net pay arrangements work the other way round. Your employer takes your pension contribution and the government's contribution as tax relief from your pay before deducting tax, and you pay tax on what is left¹³. The relief is therefore invisible: your taxable pay is simply lower. The catch is that under this arrangement, if you do not pay tax, for example because you earn less than the tax threshold, you do not get tax relief¹³.

Relief at source: you pay in from taxed pay and the provider claims the basic-rate top-up from HMRC.

The practical differences between the two arrangements are covered in full on the relief at source vs net pay page. The one that matters most is the treatment of people who earn too little to pay income tax, which is the next section.

If you earn too little to pay income tax

People with very low or no earnings are not shut out of pension tax relief, but the amount is capped. If you earn under £3,600, you can get tax relief on up to £2,880 of your pension contributions². Once the government adds basic-rate relief, those contributions are worth £3,600 in your pot. The same £3,600 figure applies if you have no earnings at all in the tax year: relief is available on contributions up to 100% of your earnings, or £3,600 if your earnings are lower⁶.

This rule is what makes pensions possible for people who are not working: non-working partners, carers, and even children, whose pensions can be funded by someone else. Stakeholder pension guidance confirms that if you do not pay tax, you can still get tax relief on your own or someone else's contributions up to that limit¹⁶.

The route matters, though. Under a relief at source scheme, a non-taxpayer automatically gets the relief: the provider claims the 20% from HMRC regardless¹³. Under a net pay arrangement, someone who earns less than the income tax threshold gets no relief at all, because there is no tax being collected from their pay to reduce¹³. This is known as the net pay gap, and it affects low earners in workplace schemes that use net pay.

If you are in a workplace pension, earning below the tax threshold and unsure which arrangement your scheme uses, the scheme administrator or your employer can tell you. If it is a net pay scheme, the relief is not lost in every case: some schemes make up the difference for low earners voluntarily, and HMRC has processes for reviewing cases where too little or too much tax has been paid across the year²⁴. The dedicated page on tax relief with no earnings goes into the options in detail.

Claiming extra relief as a higher or additional-rate taxpayer

The automatic part of pension tax relief stops at 20%. If you pay income tax at a higher rate than 20%, you need to claim the extra tax relief yourself². Higher-rate taxpayers can claim a further 20%, and additional-rate taxpayers can claim an extra 25%¹¹. Until you claim, a £100 contribution costs you £80 rather than £60.

There are two main routes:

1. Self Assessment. Higher and additional-rate taxpayers who complete a tax return claim the extra relief on it. For the self-employed, this is the standard route: you claim the relief back yourself in your Self Assessment tax return¹⁰.
2. Contacting HMRC outside a tax return. If you do not normally complete a return, you can ask HMRC to adjust your tax code so the relief is given through your pay, or make a one-off claim. Your provider still claims the 20% basic rate, but you claim back the other 20% through your Self Assessment tax return²⁰.

The claim is worth real money over time, and it is a common thing to miss. In most cases, tax reliefs can be backdated up to four years⁷, and claims for the previous four years are possible for people claiming their own relief, those without automatic relief, and higher earners claiming extra entitlement¹¹. So if you have been paying into a pension at the higher rate for several years without claiming, the recovery can stretch back across that whole period.

A few practical points on making the claim:

• The relief is given against your income tax liability for the year of the contribution, so it reduces your tax bill rather than adding cash to your pension pot.
• The claim is per tax year, and each year's claim is for contributions paid in that year.
• Records of contributions, from annual statements or your provider, are what you need to support the figures.
• If you file a return, the claim is made on the pension contributions pages; the questions to check before filing are set out in guidance for pension savers completing their returns⁶.

The step-by-step process, including how to claim without a tax return, is on the claiming higher-rate relief page.

Scottish taxpayers get different amounts

Scotland sets its own income tax rates and bands, and this changes the arithmetic of pension tax relief. Income tax rates in Scotland are different, which affects how much additional pension tax relief higher earners can reclaim⁶. Scottish higher, advanced and top rate taxpayers qualify for pension tax relief at 42%, 45% or 48% respectively, rather than the 40% and 45% that apply elsewhere in the UK⁴.

The way the extra relief is claimed also differs, because the basic rate claimed automatically by the provider is still 20%, while Scottish income tax has several bands above and below that. Official Scottish guidance sets out the additional relief available at each Scottish rate²³:

In cash terms, in Scotland you can claim an extra £1.58 for every £100 paid if you pay enough tax at the Scottish intermediate rate of 21%, and a further £26.58 per £100 if you pay enough tax at the Scottish higher rate of 42%¹⁰. The "up to the amount of any income you have paid that rate on" wording matters: the extra relief is limited by how much of your income actually falls in each band, not by your contributions alone.

Because the bands work differently, the amount of tax relief you are able to claim is slightly different in Scotland even where the headline rates look similar¹¹. Welsh taxpayers, by contrast, are covered by legislation that gives additional relief where the Welsh basic rate for the year is higher than the relevant rate applied to the contribution²⁵, though Welsh rates have not diverged from the English basic rate, so in practice the claiming process is the same as in England and Northern Ireland.

The full breakdown for Scottish residents, including worked examples at each band, is on the Scottish taxpayers page.

Salary sacrifice and the coming £2,000 cap

Salary sacrifice is a third way to get money into a pension, and it is treated differently for tax. Instead of paying contributions from your pay, you give up part of your salary and your employer pays it into your pension. Because the money never counts as your salary, neither you nor your employer pays National Insurance contributions on it, which is why these arrangements have been popular. How salary sacrifice works, and how it compares with paying in normally, is covered on the salary sacrifice page.

That National Insurance advantage is being capped. From April 2029, the amount that is exempt from National Insurance contributions will be capped at £2,000 a year for employee contributions made via salary sacrifice²⁶. The measure removes the exemption for employer pension contributions made through salary sacrifice above the annual £2,000 cap²⁷. Earnings given up under a salary sacrifice scheme above the £2,000 contribution limit for a tax year will be subject to National Insurance contributions²⁸.

The £2,000 cap was announced in the November 2025 Budget and takes effect from 6 April 2029.

The scale of the change is significant: of the employees using salary sacrifice, 3.3 million sacrifice more than £2,000 of salary or bonuses²⁸. For an individual, the effect depends on how much is sacrificed. Independent guidance gives the example of someone on a £40,000 salary who sacrifices 10%, or £4,000: with £2,000 above the cap, they would miss out on savings of £160 a year²². The cap applies to the National Insurance exemption, not to the income tax relief: all pension contributions, including those made via salary sacrifice, remain exempt from income tax, subject to the annual allowance²².

If you are deciding between salary sacrifice and paying in from your pay, the comparison page on salary sacrifice vs relief at source sets out the differences, including the effect on things like statutory pay and life cover that depend on your salary.

Where to get help if your relief is wrong

If you think the relief on your pension has been calculated wrongly, or missed altogether, there are defined routes to put it right. The legislation gives three mechanisms: relief at source under section 192 of the Finance Act 2004, relief under net pay arrangements under section 193 for occupational scheme members, and relief on making a claim under section 194 in other cases¹². In practice, that means the first question is which mechanism your scheme uses, because that determines who you contact: the scheme administrator for relief at source problems, or HMRC for net pay and claim-based problems.

For underpayments and overpayments of tax generally, HMRC will send a tax calculation letter, known as a P800, or a Simple Assessment letter if you have paid too much or too little tax by the end of the tax year on 5 April²⁴. If you owe money to HMRC, there is an online tool on GOV.UK to help you find the right guidance and support³¹. For missed higher-rate relief, the four-year backdating window⁷ is the deadline that matters most: claims made after it closes are generally refused.

Free help is available at each stage:

• MoneyHelper, the government-backed pensions guidance service, explains personal pensions and how relief should be applied, and can be reached on 0800 011 3797³².
• Your pension scheme administrator can confirm whether the scheme uses relief at source or net pay, and whether relief has actually been claimed and added.
• HMRC handles claims for extra relief, backdated claims and tax code adjustments.
• The Pensions Ombudsman deals with complaints about pension schemes that cannot be resolved with the provider, a process covered on the Pensions Ombudsman page.

If the problem is with a provider rather than with the tax calculation, the complaint route is set out on the complaining about a pension provider page. And if you are unsure whether your relief is wrong in the first place, checking a recent pension statement against the rates on this page is the quickest first step.
