HMRC refunds usually arrive within 5 to 10 working days after you submit your claim, but the timeline depends on how you claim and whether HMRC needs to verify your information

The speed of your refund hinges on three things: the method you use to claim, whether HMRC has to investigate your figures, and the time of year. If you claim through your online tax account and your return is straightforward, you might see money in your bank within a week. If HMRC flags something for review or you claim by post, you could wait several weeks.

The working-day count starts from the day HMRC receives your claim, not the day you submit it online. If you post a paper claim, add 3 to 5 working days for it to reach their office. If you claim online, the clock starts when ready.

Key Takeaways

  • Online claims through your HMRC tax account typically process within 5 to 10 working days if no issues are found.
  • Paper claims sent by post take longer because HMRC must receive and manually process them, often adding 2 to 3 weeks to the total time.
  • HMRC may hold your refund for investigation if your claim looks unusual or if they need to cross-check information with your employer or pension provider.
  • Refunds paid by BACS transfer usually arrive within 2 working days of HMRC releasing the money, but some older bank accounts may take longer.

Claiming online versus posting your claim

Claiming through your online tax account is the fastest route. Once you submit your claim, HMRC's system processes it automatically if everything matches their records. You can track the status in your account — it will show "processing" and then move to "complete" when the refund is released. This usually takes 5 to 10 working days.

Posting a paper claim adds time at every stage. Your letter takes 3 to 5 working days to arrive. Once it reaches HMRC, a member of staff has to open it, check the figures, and enter the information into their system. This manual step typically adds another 2 to 3 weeks. If you post your claim, expect 4 to 5 weeks total before the money reaches your account.

You can only claim online if you have a Government Gateway account and have registered for online tax services. If you do not have access, you can request a paper claim form from HMRC by phone or post, but this is slower.

When HMRC delays a refund for review

HMRC will hold your refund if something in your claim does not match their records or looks out of the ordinary. Common triggers include claiming a refund much larger than usual, reporting income from a new source, or having a gap in your employment history. When this happens, HMRC will contact you — usually by letter — asking for evidence. They might ask for payslips, P45 forms, pension statements, or proof of expenses.

The review period is not fixed. straightforward queries can be resolved in 1 to 2 weeks if you respond quickly with the right documents. More complex cases, such as those involving self-employment income or multiple employers, can take 4 to 8 weeks. The clock restarts once you send your evidence back to HMRC, and they need time to review it again.

You can speed this up by providing documents as soon as HMRC asks. If you wait weeks to respond, your refund waits too. Keep copies of everything you send, and consider sending documents by registered post so you have proof of delivery.

How the refund reaches your bank account

Once HMRC releases your refund, it travels to your bank via BACS, the automated clearing system that handles most UK bank transfers. BACS transfers take 2 working days from the moment HMRC sends the payment. So if HMRC releases your refund on a Monday, it should land on Wednesday.

Weekends and bank holidays do not count as working days. If HMRC releases your refund on a Friday, the 2-day clock runs through Monday and Tuesday, so you see the money on Wednesday. If they release it on a Friday before a bank holiday weekend, you might not see it until the following Thursday.

Some older bank accounts, particularly those held at smaller building societies, may take an extra day or two. If your bank uses a different clearing system or processes transfers manually, ask them how long BACS payments typically take to show in your account.

Refund timing during busy periods

HMRC processes refunds faster during quiet months and slower during the tax return important date rush. Between January and April, when millions of people file their tax returns, HMRC's workload peaks. Online claims still process within the standard 5 to 10 working days, but paper claims can take longer — sometimes 6 to 8 weeks instead of 4 to 5.

If you claim in May or later in the tax year, you will usually see faster processing because fewer people are claiming at that time. Claiming in September or October typically means your refund arrives within 3 to 4 weeks, even by post.

What to do if your refund does not arrive on time

If you claimed online and it has been more than 15 working days, check your tax account first. The status should show whether your refund is still processing, complete, or held for review. If it shows "complete" but the money has not arrived in your bank, contact your bank — the delay is usually on their end, not HMRC's.

If your claim is still showing as "processing" after 15 working days, or if it shows "held for review" with no contact from HMRC, phone the HMRC Self Assessment helpline on 0300 200 3310. Have your National Insurance number and tax reference ready. They can tell you exactly where your claim is in the queue and whether HMRC needs anything from you.

If you posted a paper claim and it has been more than 6 weeks, call HMRC. Postal claims do go missing occasionally, and HMRC can check whether yours was received and processed.

Refunds for overpaid tax through PAYE

If you overpaid tax through PAYE (Pay As You Earn) — usually because you worked part of the year or had two jobs — HMRC may refund you automatically without you needing to claim. This happens when your employer sends your final P45 form and HMRC's system calculates that you paid too much.

Automatic refunds take the same 5 to 10 working days as online claims, because HMRC processes them through the same system. You will see the refund appear in your account without having to do anything. If you think you are owed a refund but nothing has arrived after 3 months, you can claim manually through your online tax account.

Frequently Asked Questions

Can I get my refund faster if I pay a fee?

No. HMRC does not offer expedited refunds for a fee. The standard processing time applies to everyone. Some third-party tax services advertise faster refunds, but they are usually just claiming the refund on your behalf through the normal HMRC system — the speed is the same.

What if HMRC owes me interest on my refund?

HMRC pays interest on refunds that take longer than a certain time to process, but only in specific circumstances — usually when HMRC has delayed processing a claim without good reason. The interest is calculated from the date you overpaid the tax, not from the date you claimed the refund. HMRC will add this to your refund automatically if you are may have access to to it.

Do I need to do anything after I claim, or just wait?

If you claim online, check your tax account occasionally to see the status. If HMRC needs anything from you, they will send a letter or message in your account. If you do not hear from them within 15 working days and your status shows "complete", the refund should be on its way to your bank. If you posted a paper claim, keep a copy of what you sent in case HMRC asks for it again.

What happens if I claim a refund but then realise I made a mistake?

If you claim online and have not yet received the money, you can amend your claim through your tax account before it is processed. If the refund has already been released to your bank, you cannot cancel it, but you can contact HMRC to correct the error on your next tax return. If you claimed too much, HMRC will ask you to repay the difference.
