State Pension Tax 2026: The £22 Buffer and What It Means The state pension tax 2026 issue is quite simple. The UK government froze the personal tax allowance at £12,570 until 2031. Meanwhile, the State Pension keeps rising due to the triple lock. From April 2026, the full new State Pension will be £241.30 a week. That works out at £12,547.60 a year. This leaves only £22 of tax-free space before you hit the allowance. However, by April 2027, the pension will likely pass the allowance.
