Every year, millions of people in the UK pay more tax than they should. In 2025, HM Revenue & Customs (HMRC) is issuing refunds worth hundreds of pounds, and many taxpayers are receiving official letters or online notifications. While some refunds are sent automatically, in many cases you need to submit a claim to get your money back.
The good news is that HMRC allows you to complete the process safely and quickly online. But it’s essential to understand the correct steps, to avoid delays or falling for scams.
Log Into Your HMRC Account
Go to the official GOV.UK website and sign in to your Personal Tax Account using your Government Gateway ID. Never use links from suspicious emails or text messages.
Once logged in, you will see if HMRC has calculated that you are owed a refund.
Review Your P800 or PA302
If you’ve received a P800 letter (for PAYE taxpayers) or a PA302 calculation (for self-assessment), the same details should appear in your online account. This will confirm how much you are entitled to and the reason for the refund.
Choose How to Receive Your Refund
You usually have two options:
- Direct bank transfer – fastest method, often completed within 5–10 working days.
- Cheque by post – slower, but still available if you prefer not to share bank details online.
Always provide your account details directly through GOV.UK. HMRC will never ask for them via email or text.
Submit Your Claim
Click on the “Claim your refund” option and follow the instructions. Double-check all details before submitting to avoid errors. Once submitted, you’ll receive a confirmation message on screen and usually by email.
Wait for Processing
Refunds via bank transfer are typically processed within one to two weeks. Cheques may take longer, especially during busy tax periods.
Tips to Speed Up Your Refund
- Make sure your bank details are correct.
- Respond quickly if HMRC requests extra documents.
- Avoid duplicate claims — submitting more than once can delay processing.
- Keep your contact details updated in your online account.
Common Mistakes to Avoid
- Using unofficial websites that promise “fast-track refunds” for a fee.
- Ignoring letters because you assume they are scams — always verify first.
- Forgetting to update your employer or pension provider with correct tax codes.
