Millions of Pensioners Hit by HMRC Income Tax Error — What to Check Now

The latest HMRC pensioner income tax error is not about a huge individual bill, but the scale of the mistake makes it serious. Millions of older taxpayers may have paid more than they owed because of how HMRC calculated state pension income after the annual uprating.

The issue, reported by The Sunday Times and The Independent, affects pensioners paying income tax through self-assessment and some still working under PAYE. HMRC has apologised, says the usual impact is around £5, and is aiming to fix the problem later this summer.
