One million Brits missing tax refunds

HM Revenue & Customs (HMRC) has warned that up to 1m taxpayers may be missing out on unclaimed tax refunds averaging £453 each. Many individuals have not checked their accounts, risking significant financial loss. Common reasons for overpayments include incorrect tax codes and job changes. HMRC stressed that refunds are not automatic; claimants must check their personal tax accounts on GOV.UK or the HMRC app.
