If you think you have overpaid tax in the UK, you can check your record directly using official HM Revenue and Customs (HMRC) services. The standard route is designed for checking Income Tax paid during the previous tax year, but your specific tax situation determines whether an online claim is available or if a different process applies.
Checking your record shows how much tax you paid and indicates whether a repayment might be due; it does not guarantee an automatic refund.

Checking Income Tax Paid for the Previous Tax Year
You can review Income Tax paid during the previous tax year using the official GOV.UK service for checking Income Tax paid last year. This is separate from the route for tax paid partly through Self Assessment and from other refund routes.
How to Access the Service
- Online via GOV.UK: You can sign in using your existing Government Gateway or personal tax account details.
- HMRC App: You can access your personal tax details directly via the official HMRC mobile app.
- Identity Verification: When accessing your account, you will typically need to complete standard identity verification steps.
Once signed in, the service displays your tax calculation for the previous tax year.
The Role of the P800 Tax Calculation
Where HMRC provides a P800 tax calculation and it says that you can claim your refund online, the digital service will allow you to submit your claim details directly.
If your calculation indicates another method—or if you have not received a P800 indicating an online claim route—you must follow the specific instructions provided by HMRC.
If you are unable to set up or access a personal tax account online, you will need to use HMRC’s official contact routes to check your status.

When the Standard Online Check Does Not Apply
The general Income Tax checking tool does not cover every circumstance. Depending on how you receive income or pay tax, your refund route may differ materially:
Self Assessment Taxpayers
If you pay tax partly or wholly through Self Assessment, you cannot use the standard PAYE Income Tax checking service to claim a refund:
- Claiming via the Return: Self Assessment repayments are generally claimed directly through your Self Assessment tax return.
- 45-Day Rule on Upcoming Liabilities: If you have tax due within the next 45 days—including an upcoming payment on account—HMRC may reduce or withhold your refund to cover that liability.
- Pending Status: Self Assessment repayments may remain “pending” while HMRC approves and processes or pays the repayment. A pending status does not mean your claim has been rejected.
Other Specific Circumstances
HMRC provides distinct routes and procedures for other specific situations rather than handling them through a single universal form. These include:
- Job expenses and professional fees
- Pension income or lump-sum withdrawals
- Redundancy payments
- Income from overseas or foreign residency issues
- Payment Protection Insurance (PPI) interest refunds
- Purchased life annuities
Because the correct procedure depends entirely on your personal circumstances, you should check HMRC’s official guidance on claiming a tax refund to identify the appropriate form or process for your situation.

Protecting Yourself from Refund Scams
Verify suspicious HMRC refund communications through HMRC’s official guidance and its stated checking and reporting routes:
- Verify Official Sender Details: HMRC publishes lists of genuine email communications, including those under the “Tax refund — P800” category, to help you verify authentic correspondence.
- Requests for Personal Information: Some HMRC communications will not ask you to provide personal or financial details directly via email.
- Never Share Details via Unsolicited Links: Do not click on unexpected links or enter banking or personal data into web pages reached through unsolicited emails or text messages.
- Report Suspicious Messages: If you receive an email or message claiming to offer an HMRC refund that looks suspicious, use HMRC’s official reporting routes and check their published list of recent contact methods.
Always navigate directly to GOV.UK to sign in to your personal tax account rather than clicking links inside emails or external websites.
