The Pensioner Tax Trap

The full new State Pension is now £12,547.60 per year. The income tax personal allowance is frozen at £12,570 until at least 2031. The gap is just £22.40 per year. At the current rate of triple lock increases pensioners could begin paying income tax within one to two years.

Warning: If you receive the full State Pension plus any other income — private pension savings interest rental income — check whether you owe income tax at gov.uk/personal-tax-account.

Political Debate

  • OBR estimates triple lock costs £12 billion more per year than earnings-linked rises alone
  • Government has committed to maintaining it for this parliament
  • Critics argue it is unaffordable as the population ages
  • Supporters say it protects pensioners from poverty

Bottom line: The triple lock delivered 4.8% in April 2026 — taking State Pension to £241.30 per week. The gap to the income tax threshold is now just £22. If you have any other income alongside your State Pension check your tax position now.
