HMRC urges Britons to be on the lookout for refund letters after tax ‘mistakes’

New research suggests that around 7.6 million people, including many PAYE employees, could be entitled to a tax refund from HM Revenue and Customs (HMRC).

The tax authority is about to start distributing a large number of P800 forms so that people can claim back the money they are owed. The P800 is a tax calculation carried out by HMRC to ensure that everyone pays the correct amount of tax.




If HMRC determines that a person has overpaid or underpaid tax, it will send a letter containing a P800 form. In most cases, the P800 affects employees who pay PAYE tax, rather than the self-employed, Express reports. Finance specialists RIFT carried out the new research and calculated that around 7.6 million people could receive these forms.

A RIFT spokesperson explained: “RIFT has analysed historical data showing the number of P800 forms distributed by HMRC and used this to calculate a forecast of the number of forms HMRC will send out in 2024, thereby revealing how many people in the UK could be due a tax refund.

“In 2015, HMRC sent out seven million P800 forms. It is estimated that there were over 26.4 million PAYE employees in the UK in that year, so around 26.5 per cent of people were sent P800 forms. It is estimated that by 2024 there will be over 28.5 million PAYE employees. If HMRC sends P800 forms to 26.5 per cent of them, that means almost 7.6 million people can expect to receive one in the post.”

To receive a P800 form, HMRC must have calculated that a person has overpaid or underpaid tax. If HMRC calculates that you have overpaid tax, you will be entitled to a refund. Conversely, if it is thought that you have underpaid, you may have to pay more.

People are being urged to be on the lookout for letters arriving on their doorsteps in the coming weeks, which will result in a significant increase in the cost of living.
