How SIPP Tax Relief Works in 2026

Basic-rate relief normally goes into the SIPP automatically, while higher-rate relief usually does not, so an extra tax claim should not be mistaken for another pension payment.

What leaves the bank, what reaches the SIPP and the net cost after any further claim are three different parts of the transaction.

How relief at source works

In the £100 gross contribution example, the saver pays £80 and the SIPP provider claims £20 from HMRC. The 20% relief is calculated on the £100 gross amount, which is why adding 20% to £80 produces the wrong answer.

The provider usually claims the basic-rate amount automatically, although the top-up may take time to reach the account.

Higher and additional-rate relief

Higher-rate taxpayers may claim another 20 percentage points on the part of a contribution matched by higher-rate income, while additional-rate taxpayers may claim another 25 percentage points on the relevant part.

Extra relief can be claimed through Self Assessment, a tax-code adjustment or a direct claim. Contribution statements provide the evidence needed to match the claim to income taxed at the relevant rate.

Contribution examples at different incomes

Higher-rate relief applies only to the part of a contribution matched by income otherwise taxed at 40%, so these examples do not assume it for the entire payment.

The gross contribution calculation comes before identifying taxable income in each band. Scottish income tax bands differ from those in England, Wales and Northern Ireland.

Annual allowance and earnings limits

The standard annual allowance is £60,000 and includes employer contributions. Tapering and the Money Purchase Annual Allowance can reduce it, while relevant UK earnings limit personal tax-relieved contributions.

An eligible person with low or no relevant UK earnings can normally pay up to £2,880 net into a relief-at-source pension and receive £720 of basic-rate relief, producing a £3,600 gross contribution. The normal relevant-earnings limit applies above that exception.

Carry forward can use unused allowance from the previous three tax years, but it cannot create earnings for personal contribution relief. Advice is sensible before a large contribution involving tapering, carry forward or previous pension access.

Tax-relief mistakes to avoid

Higher or additional-rate relief applies only to income taxed at that rate. The annual allowance and personal earnings limit are separate constraints.

The workplace contribution method can change whether a claim is needed because relief at source, net pay and salary sacrifice show relief differently.
