Your P800 tax calculation will tell you how you can get your refund.
If your P800 says you can claim online
Your P800 will tell you if you can claim your refund online. You’ll be sent the money within 5 working days – it’ll be in your UK account once your bank has processed the payment.
If you do not claim within 21 days, HM Revenue and Customs (HMRC) will send you a cheque. You’ll get this within 6 weeks of the date on your P800.
Contact HMRC if you cannot claim your refund online.
If your P800 says you’ll get a cheque
Your P800 will tell you if HMRC will send you a cheque. You do not need to make a claim.
You’ll get your cheque within 14 days of the date on your P800. If you’re owed tax from more than one year, you’ll get a single cheque for the entire amount.
Can I check my P800 online?
Your P800 will arrive after the relevant tax year has ended in April. You’ll usually receive it around September. Your P800 will tell you all about claiming online through the GOV.UK website. If you’re able to claim online, the income-tax refund will appear in your bank account within about five days.
If you do not have a P800
You can check how much Income Tax you should have paid.
Contact HMRC if you think you’ve paid too much tax. If they agree, they’ll send you a P800.
