SIPP Tax Relief Explained: How Much Is Added? (2026/27)

When you pay into a SIPP or other personal pension, your provider claims basic-rate tax relief of 20% from the government and adds it to your pot. If you pay tax at 40% or 45%, you can claim the extra relief yourself through Self Assessment or by contacting HMRC. Your provider will not add that part for you.

The rest of this guide explains how the relief is worked out, walks through an example, and covers the limits and mistakes to watch for.

What pension tax relief actually is

Some of your income would normally go to the taxman. When you pay into a pension, part of that money goes into your pension instead. That is tax relief.

You get relief at the highest rate of tax you pay on the slice of income you put in. For 2026/27 in England, Wales and Northern Ireland, the bands are:

Scotland has different tax bands, so the figures are different there. If you live in Scotland, check the Scottish rates on GOV.UK before you work out your own relief.

Relief at source vs net pay: why a SIPP is different

Pension schemes pay tax relief in one of two ways. Which one your scheme uses changes what you have to do.

• Net pay: your employer takes the contribution from your pay before tax is worked out. You get all your relief automatically, at whatever rate you pay, and there is nothing to claim.
• Relief at source: you pay from money that has already been taxed, for example from your bank account. Your pension provider then claims 20% from the government and adds it to your pot.

SIPPs and most other personal pensions use relief at source. So does a large share of workplace schemes. That means basic-rate relief turns up on its own, but anything above that does not.

If you pay tax at 40% or 45%, the extra relief does not go into your pension. You have to claim it from HMRC, and it comes back to you through your tax, not as a top-up to your pot.

How much your provider adds: a worked example

This example uses figures from GOV.UK. The original is from an earlier tax year, but the bands have not changed, so it works the same way for 2026/27.

You earn £60,270 and you pay into a SIPP that uses relief at source.

1. You pay in £12,000 from your bank account.
2. Your provider adds £3,000 in basic-rate relief. That is 20% of the total that ends up in your pot.
3. £15,000 goes into your pension.
4. You claim back £2,000 more. The top £10,000 of your income is taxed at 40%. Your provider has already given you 20% relief, so you can claim the other 20% on that £10,000, which is £2,000.

The point to notice is that the provider's top-up is worked out on the total going into the pot, not on the amount you paid. Your £12,000 is treated as what is left after basic-rate tax has been taken off a £15,000 contribution. This is the part that most often catches people out when they try to check the numbers.

The extra 20% is only due on income that is actually taxed at 40%. In the example, only £10,000 of the contribution sits in the higher-rate band, so that is the only slice you can claim the extra on. For your own figures, see our full guide on how pension tax relief works.

How higher and additional-rate taxpayers claim the extra

If you pay tax at 40% or 45% and your pension uses relief at source, you can claim the extra relief in two ways:

• Through your Self Assessment tax return, if you already fill one in. You enter the contributions you made to relief-at-source pensions.
• By contacting HMRC, if you do not do Self Assessment.

HMRC may then give you the relief by changing your tax code or by cutting your tax bill. Either way, the money reaches you through your tax, not through your pension.

The 60% effect between £100,000 and £125,140

If your income is between £100,000 and £125,140, you lose £1 of your tax-free Personal Allowance for every £2 you earn over £100,000. A pension contribution lowers the income used for this test. You save the 40% tax and also get some of your allowance back.

On that slice of income, the overall saving can be about 60%. Anyone in this income range should check their figures carefully.

The limits you need to know

Tax relief is generous, but it has limits:

• 100% of your earnings: you get tax relief on contributions up to 100% of your yearly earnings.
• Annual allowance: for most people the annual allowance is £60,000. It can be lower if you have a very high income, or if you have already taken money out of a pension in certain ways.
• Carry forward: you might be able to use annual allowance you did not use in the previous 3 tax years.
• Tax charge: going over the allowance can mean a tax charge, so check with HMRC if you are close to it.

Before you decide, check these as well:

• Money in a pension is locked away until you reach the minimum pension age. It is currently 55 and is due to rise, so check GOV.UK for the age that applies to you.
• A private pension is extra to your State Pension, not a replacement for it. Our guides to how the new State Pension works and State Pension age explain what you can expect from it.

Common mistakes

• Expecting the provider to add higher-rate relief. Your provider only claims 20%. You must claim the rest yourself.
• Claiming the extra on the whole contribution. You only get the extra on the part of your income actually taxed at 40% or 45%, as the worked example shows.
• Getting the gross and net amounts mixed up. The 20% top-up is worked out on the total going into the pot, not on the amount you paid in.
• Thinking you need to pay tax to get any relief. If your income is below the Personal Allowance, a net pay scheme gives no relief, but relief at source still adds 20%.
• Using the wrong tax bands. Scotland's bands are different, so the figures here may not match yours.
• Ignoring the annual allowance. Big contributions, especially using carry forward, can trigger a tax charge if you get them wrong.

Check your own number

The worked example shows how the sums work, but your figures will depend on your income and how much you pay in. Put your own numbers into the pension tax relief calculator. It shows how much your provider adds, how much you might claim back, and what your contribution really costs you. If you are near the annual allowance or your income is in the 60% range, check with HMRC or GOV.UK before you rely on the result.
