P800 Refund

Independent UK guidance for P800 refunds and HMRC letters.

Official HMRC links matter. This site explains the process in plain English and points readers towards official GOV.UK routes.

Independent website

Disclaimer

Independent UK guidance for readers checking HMRC letters, the 2025/26 tax year and the official GOV.UK route. We are not affiliated with HMRC or GOV.UK.

Important notice

  • P800 Refund is not HMRC or GOV.UK.
  • We provide independent P800 guidance only.
  • GOV.UK provides the official service and should always be used for claims or sign-in.

This is not the official GOV.UK or HMRC website. P800 Refund is an independent informational website and is not part of HMRC, GOV.UK, or any government department.

Content on this site is provided for general information only. It is not personal tax advice, legal advice, or financial advice, and it should not be relied on as a substitute for official guidance or professional advice tailored to your own circumstances. If you need the broader context first, start with the P800 refund guide or What Is a P800?.

If you need to claim a P800 refund, confirm an HMRC process, or sign in to a tax account, you should complete the actual process through the official GOV.UK route. The official service can be found through GOV.UK guidance for P800 refunds, and that official route should always take priority over anything written on this site.

Official service

Use the live GOV.UK route if you need to claim a refund, enter a P800 reference number or continue with an HMRC repayment step.

We aim to explain processes clearly, but official guidance can change. If there is any difference between our summaries and current official information, the official GOV.UK guidance should take priority. Please also read our About page and Privacy Policy for more detail about how the site works. If you are ready to continue safely, use the step-by-step claim guide.

While we link to official GOV.UK pages for convenience, we are not responsible for the content, availability or accuracy of external sites. You should always check the live wording on GOV.UK before taking action.
