Money Marketing reported on 21 October 2026 that the Office for National Statistics confirmed September's CPI inflation figure at 3.5%, up from 3.1% in August. On the back of that figure, the article reports the full new State Pension is expected to rise from £241.30 to around £250.70 a week, £13,036.40 a year, from April 2027. The Personal Allowance stays frozen at £12,570. For the first time, a client with no income beyond the full new State Pension is expected to owe income tax on it alone, by £466.40.
How close the state pension already sits to the allowance
This has been close for a while. In 2026/27 the full new State Pension is £241.30 a week, £12,547.60 a year, against a Personal Allowance of £12,570. That leaves £22.40 unused, a figure set out in a million pensioners paying higher rate tax. The freeze on the allowance, confirmed in HMRC's policy paper of 26 November 2025, holds it at £12,570 until 5 April 2031. The state pension, by contrast, rises each April under the triple lock. One of those two numbers was always going to catch the other.
Money Marketing's reporting puts the April 2027 rise at around £250.70 a week, £13,036.40 a year. Against the same frozen £12,570, that is £466.40 of income with no allowance left to cover it.
Collecting the tax with nothing deducted at source
The state pension is paid gross. No PAYE is taken from the payment itself, so a small liability arising from the state pension alone cannot be collected the way it would be from a salary or a private pension in payment.
Where a client has another PAYE source, a private pension or part-time earnings, HMRC's usual route is to code out the state pension against that income, reducing the client's tax-free amount on the other source instead. Where a client has no other PAYE income at all, HMRC issues a Simple Assessment, a tax calculation sent directly to the client outside self assessment. What a Simple Assessment letter tells you about a client sets out the mechanics of that letter, and what around 1.8 million of them for 2025/26 show about a client's position.
The FCA's Financial Lives 2024 survey found that 8.6% of UK adults, and 13% of self-employed adults, had taken regulated financial advice in the previous twelve months. A state-pension-only client, by definition, has limited other income to review, but the accountant is often the only person who sees the full return each year, including any small amount of savings interest sitting alongside the pension.
