HMRC urges UK taxpayers to check for possible tax refunds due to income or life changes.

HMRC is urging UK residents to check if they're owed tax refunds, warning that around one million people annually miss out on reclaiming overpaid taxes. The agency, promoting its official app on X, said changes in income, employment, or personal circumstances may entitle individuals to refunds. It encouraged taxpayers to review their status and claim money they’ve already paid but are not required to keep.
