HM Revenue and Customs (HMRC) has begun issuing approximately four million tax refund letters, starting June 1, with the process continuing until the end of August. The letters, known as P800 notices, detail specific income tax refunds owed to individuals who have overpaid during the financial year.
Taxpayers are urged to respond promptly to these letters to claim their refunds. HMRC officials stated: "You must respond to the letter so we can make any repayments owed to you as soon as possible." Last year, nearly one million people failed to claim their refunds due to not responding, with the average unclaimed amount being £473.
Overpayments typically occur due to incorrect tax codes, job changes, or working multiple jobs simultaneously. HMRC reviews records after the tax year ends in April to identify those eligible for a refund.
The quickest way to claim is through a Personal Tax Account or the HMRC app, with payments typically processed within five working days. Those opting for a cheque may wait up to six weeks. Some taxpayers may need to submit manual claims depending on their circumstances.
