Overview
- HMRC says almost one million people did not claim refunds last year, with successful payouts averaging about £473.
- People who receive a P800 tax calculation can claim in the HMRC app or online, or they can wait for a cheque in the post.
- Incorrect PAYE tax codes are the main cause of overpayment, often after a job change, starting a pension or working part of the year.
- HMRC reports paying about £3 billion to 4.2 million PAYE taxpayers last year, while an FOI from UHY Hacker Young points to 5.6 million overpaying around £3.5 billion.
- HMRC advises claiming directly to avoid commission-charging firms and urges people to check their code and claim within the four-year deadline.
