HMRC Issues P800 Tax Refund Alert: Millions Could Claim Money Back
HMRC P800 Tax Refund: How to Check and Claim

HM Revenue and Customs (HMRC) has issued a direct alert to UK taxpayers, informing them that they could be in line for an unexpected financial boost through a tax refund. The tax authority has clarified the process for individuals to check if they have overpaid on income tax related to their pension, employment income, or other sources.

How to Know if You Are Owed a Tax Refund

In a recent social media post on X, the platform formerly known as Twitter, HMRC prompted the public with a simple message: "Think you’re owed a tax refund? Manage your money and tax easily with the HMRC app." This straightforward nudge could lead to significant repayments for those who have paid too much tax, a situation known technically as a rebate.

The scale of this issue is substantial. A 2022 report by Kantar for HMRC revealed that a high volume of people in the UK end up paying an incorrect amount of tax each year. The report highlighted that HMRC issued around 3.5 million P800 tax overpayment notices in 2021 alone.

A P800 is a formal letter sent to taxpayers which details whether they have paid too much or too little tax. This document outlines the exact amount of money involved and explains the procedure for either making an additional payment or receiving a refund.

Common Reasons for Overpaying Tax

HMRC lists several common scenarios where you might have overpaid tax and be eligible for a refund. These include, but are not limited to:

  • Job-related expenses, such as costs for working from home, fuel, specialist work clothing, or tools.
  • Income from savings or Payment Protection Insurance (PPI).
  • Pay from a job or a redundancy payment.
  • Income from a life or pension annuity.
  • Pension income.
  • Income from Self Assessment tax returns, foreign income, or UK income earned before moving abroad.

Using the HMRC App for Tax Management

HMRC strongly recommends using its official app, describing it as a "quick and easy way" to manage your tax affairs. Beyond checking for potential refunds, the app allows you to:

  • View your income, benefits, and tax code.
  • Check your State Pension forecast and National Insurance number.
  • Review your employment and income history from the last five years.
  • Find and pay gaps in your National Insurance contributions.
  • Use a tax calculator to estimate your take-home pay.
  • Update your personal details like your name and address.
  • Track forms and letters sent to HMRC.

The app is available for free download from both the App Store and Google Play. For those who prefer online services, HMRC also provides a dedicated tool on the GOV.UK website to guide you through the process of checking and claiming a tax refund.
