If you are due a tax refund from HMRC because of an overpayment you have made to them, don’t leave it too late to claim your money back: HMRC may not refund you! HMRC says the taxpayer must make the overpayment relief claim within four years of the end of the relevant tax year or accounting period. That means that if the overpayment occurred in the year ended 5th April 2020 you have until 5th April 2024 to make your claim. After that the money is gone for good.

If you are due a tax refund from HMRC because of an overpayment, don’t leave it too late to claim your money back—HMRC may not refund you!
You may have overpaid H.M. Revenue & Customs (HMRC) for a whole variety of reasons:
- Your PAYE coding may have been wrong
- You may have forgotten to claim relief for something like a pension contribution or Gift Aid
- Your letting agent may have paid tax on your behalf that was greater than your liability for the year
- You may have simply overpaid when paying your instalments of tax.
HMRC says the taxpayer must make the overpayment relief claim within four years of the end of the relevant tax year or accounting period. So, for instance, that means that if the overpayment occurred in the year ended 5th April 2020 you have until 5th April 2024 to make your claim. After that the money is gone for good.
HMRC goes on to say a taxpayer cannot appeal HMRC’s refusal to accept a late claim.
