Overview

You can use form R40 to make a claim for repayment of tax in certain circumstances:

  • you are not within self assessment – that is you do not have to submit an annual tax return, and
  • you have paid too much tax on interest from your savings and investments (including purchased life annuities or PPI payouts), and
  • you are resident for tax purposes in the UK.

You can download form R40 from GOV.UK or complete an online version. See our guidance on How to claim for more information on all the options.

Time limits

You have four years from the end of the tax year to make a claim. So, for 2025/26, you must make a claim by 5 April 2030. As we are in 2025/26, you can make a claim going back to the 2021/22 tax year.

It is possible to use the form to claim a repayment of tax relating to the current tax year (known as an ‘interim claim’) if you know what your income is going to be for the year. You should complete the form using your best estimate for the total annual figures you expect to receive from each source of income and mark the form as an interim claim by ticking box 1.8. When HMRC receive the form, they will issue a repayment (if one is due) based on the estimated figures reported. After the end of the tax year, HMRC will then check the position and inform you if there is any discrepancy.

Method of repayment

HMRC make repayments by cheque – they will either send the cheque to you or you can ask them to send it to someone else (your nominee).

How to complete the form

We also suggest that you read through HMRC’s guidance on how to complete form R40, available on GOV.UK. You need to click on the green ‘Start now’ button and answer a few questions to get to the guidance.

We use the annotated form plus example below to illustrate how you should complete form R40. Please do not use the details provided in the example when completing your own form.

Example - R40 claim

Patrick, who was born 1 February 1953 (National Insurance number QQ 12 34 56 Q), had the following income in 2022/23:

  • Employment income gross: £18,000 (tax deducted £1,100)
  • Building society interest gross: £100 (tax deducted £nil)
  • NS&I interest gross: £50 (tax deducted £nil)
  • ISA interest gross: £200 (tax deducted £nil)

Patrick also received a pay-out of PPI compensation. This consisted of a refund of the premiums he had paid and also PPI interest.

The letter Patrick received, confirming the decision to pay him compensation, contained a breakdown of the amount that looked something like this:

    £
A Full refund of PPI payments

1,000
B Associated interest paid on them

200
C 8% interest

400
D Gross redress amount (A+B+C)

1,600
E Income tax deducted (20% x C)

80
F Net interest paid to you

320

Patrick is making a claim after the end of the tax year and he wants HMRC to send the cheque direct to him.

We use the annotated form to show how to complete form R40 using Patrick’s details:

As Patrick’s claim includes interest on PPI compensation, Patrick will also need to send in the letter as documentary proof of his award. He takes a copy before sending in the award letter along with his form.

Once HMRC have received and processed Patrick’s form, he should get a refund of £94 – being the £80 of tax withheld on his PPI interest (as he can use the personal savings allowance against all his savings income) and a small amount due to an over withholding of PAYE on his employment income (£18,000 less the personal allowance £12,570 = £5,430. 20% x £5,430 = £1,086).
