If a bank deducted 20% tax from the statutory interest inside your PPI compensation, you can often claim a PPI tax rebate from HMRC using Form R40, provided your total savings interest for that tax year sat within your allowances. The window is four years from the end of the tax year you received the payout. For payouts received during 2021/22, that means claiming by 5 April 2026.
Why There’s Tax to Reclaim
A PPI payout came in two parts. The refund of premiums you originally paid is not taxable. The statutory interest, calculated at 8% a year on those premiums, is taxable savings income in the year you received it.1HM Revenue & Customs. Savings and Investment Manual – Interest: Payment Protection Insurance (PPI) Compensation2GOV.UK. Tax on Savings Interest: How Much Tax You Pay
Banks took 20% basic-rate tax off that interest before paying you and sent it to HMRC. Many people never actually owed it, because their savings interest fell inside their tax-free allowance or their income was low enough to attract extra relief. That deducted money is what an R40 claim recovers.
Who Qualifies
Eligibility depends on two things: your total savings interest for the year of the payout (PPI interest plus any other savings interest), and your income tax band that year.
Personal Savings Allowance
Basic-rate taxpayers can earn £1,000 of savings interest a year tax-free. Higher-rate taxpayers get £500. Additional-rate taxpayers get nothing.2GOV.UK. Tax on Savings Interest: How Much Tax You Pay If your combined savings interest for the year fell inside your allowance, the 20% deduction was unnecessary and you can reclaim it in full. If you went slightly over, you can still reclaim the tax on the portion that sat within the allowance.
Starting Rate for Savings
If your non-savings income (wages, pension and the like) was below £17,570, you may also qualify for a starting rate for savings worth up to £5,000, which sits on top of the Personal Savings Allowance. Every £1 your non-savings income exceeds the £12,570 Personal Allowance reduces the £5,000 band by £1.2GOV.UK. Tax on Savings Interest: How Much Tax You Pay
This matters for retirees, part-time workers, and anyone on a modest income when the PPI money came in. Take someone earning £14,000 in wages: their starting rate for savings would be £3,570, and adding the £1,000 Personal Savings Allowance gives £4,570 of tax-free savings interest. If the PPI statutory interest sat below that, every penny of the 20% deduction is reclaimable.
The Higher-Rate Trap
Higher-rate taxpayers can still reclaim if their total savings interest stayed inside the £500 allowance. But watch the arithmetic: the bank only deducted 20%, while higher-rate taxpayers owe 40% on savings interest above the allowance. If the PPI interest pushed you over, you may actually owe HMRC an additional 20% rather than being due a refund. Additional-rate taxpayers face the same problem at 45%. Check the numbers before you file.
A Worked Example
You earned £28,000 in wages and received a PPI payout containing £600 of statutory interest. You also had £250 of interest from a savings account. Your total savings interest for the year was £850, comfortably inside the £1,000 basic-rate allowance. The bank deducted £120 (20% of £600) that you never owed. You can claim the full £120 back.
Claim Deadlines
You have four years from the end of the tax year in which the payout was received. After that, the year closes for good.2GOV.UK. Tax on Savings Interest: How Much Tax You Pay The UK tax year runs 6 April to 5 April. The current deadlines are:
- Payout received 6 April 2021 to 5 April 2022 (tax year 2021/22): claim by 5 April 2026
- 2022/23: claim by 5 April 2027
- 2023/24: claim by 5 April 2028
- 2024/25: claim by 5 April 2029
The FCA’s deadline for PPI complaints was August 2019, but banks continued processing and paying complaints well into 2020 and 2021. Look at the date on your settlement letter, not the date you complained. The tax year the payout falls into is what sets your deadline.
What You Need Before You Start
Since October 2023, HMRC has required evidence of the PPI payment attached to the claim. Without it, the claim won’t move. Acceptable evidence is either the final response letter from the bank, or a certificate from the bank confirming the tax deducted.3HM Revenue & Customs. Claim a Refund if You Have Paid Tax on Your Savings and Investments
The settlement letter is the more useful document because it breaks out the three figures the form needs: gross statutory interest, tax deducted, and net interest paid to you.
You’ll also need your P60 or final payslip for the tax year, to confirm your total earnings and which band you were in. Gather records of any other savings interest you earned that year too, because the allowance covers all your savings interest combined, not just the PPI portion. Lost the settlement letter? Ask the bank to reissue a certificate showing the breakdown; they’re required to hold the records.
How to File
The R40 Online
HMRC’s R40 is the standard route. You start on GOV.UK and work through the form, entering your income for the year and the figures from your settlement letter: gross savings interest, tax deducted at source, and other income.3HM Revenue & Customs. Claim a Refund if You Have Paid Tax on Your Savings and Investments
You can use the online R40 if your gross savings and investment income was £10,000 or less and your gross property income was £10,000 or less. Most PPI claimants fit inside those limits.
Even after completing the R40 online, you still need to post your PPI evidence. The dedicated address for PPI tax interest claims is:4GOV.UK. Repayments: Where to Send Claim Forms

If you’d rather work on paper, you can complete the form through the same GOV.UK page, print it, and post it with your evidence to BX9 1ZR. Don’t send PPI claims to the general PAYE R40 address (BX9 1AS); it’s for other R40 claims and will slow things down.4GOV.UK. Repayments: Where to Send Claim Forms
Common Mistakes on the Form
The form asks separately for gross interest (before tax) and net interest (what you actually received). Mixing them up is the most frequent error. Your settlement letter labels both clearly. Declare any other savings interest earned in the same year, because HMRC calculates the refund against your full savings income, not the PPI slice alone. Keep copies of everything; if HMRC comes back with a query, you’ll respond faster.
If You File Self-Assessment
Don’t use Form R40 if you already file an annual Self-Assessment return. Instead, report the PPI statutory interest as savings income on the return for the year you received the payout, and record the tax the bank deducted so HMRC credits it against your liability. If you’ve already filed that year’s return without the PPI interest, you can amend it within 12 months of the filing deadline or contact HMRC to correct the figures. Higher- and additional-rate filers should double-check: only 20% was taken at source, and you may owe more rather than be due a refund.
If You Live Outside the UK
Non-UK residents can also reclaim, but the form is R43, designed for people claiming personal allowances and refunds from abroad.5HM Revenue & Customs. Claim Personal Allowances and Tax Refunds if You Live Abroad The four-year deadline is the same. You may need a tax certificate from your country of residence, and it’s worth checking any double taxation agreement between the UK and where you live. Married couples and civil partners abroad are treated separately for UK tax and must claim individually.
Claiming on Behalf of Someone Who Has Died
A personal representative or executor can file for the estate of someone who received a PPI payout but never reclaimed the tax. The R40 process is the same, and the four-year deadline runs from the end of the tax year the deceased received the payout. You’ll need the original settlement letter (or a reissued certificate) and proof of your authority to act, such as a grant of probate or letters of administration.
Don’t Pay a Company to Do This For You
Claims management firms market PPI tax refund services aggressively. Reported charges run from 28% to nearly 50% of the refund. Some use “deed of assignment” arrangements that sign over your right to the money entirely, so the refund goes to them and they pass on what’s left. If HMRC later finds a claim submitted by an agent was inflated or fraudulent, you are the one held liable.
HMRC charges nothing to process an R40. The online tool walks you through it, and the real work is gathering your settlement letter and income records. For most people, filing takes under an hour. If someone contacts you out of the blue claiming you’re owed a refund and offering to sort it for a fee, verify by signing into your HMRC account at GOV.UK before sharing anything.
