Experts warn that, if tax is due on the state pension, thousands of people delaying retirement to boost their income could inundate Westminster with additional confusion and paperwork.
Andrew Tully, of Canada Life, said: “If state pension income starts to exceed the personal allowance, individuals would need to complete a self-assessment return and submit it to HMRC, which could cause confusion and greater bureaucracy.
“If this were to happen with much greater frequency due to the freezing of the personal allowance, the Department for Work and Pensions and HMRC may need to work together to deduct tax from the state pension.”
