Our view, before the detail
This isn't really a story about the State Pension going up — it does that most years, and by design. It's a story about two government promises that were always going to collide, and this week is the moment the collision got a number attached to it. One promise, the triple lock, guarantees the State Pension keeps rising with wages or prices. The other, the frozen personal allowance, has kept the tax-free threshold nailed to £12,570 since 2021 and, as of a decision confirmed this year, will keep it there until April 2031. Something that keeps rising was always going to meet something that doesn't move. That something is now due to happen in a single pay rise, next April.
The actual money at stake for most affected pensioners is genuinely small — we've worked it out below, and it's under £2 a week. What matters more is what the story reveals: a promise made at Budget 2025 that pensioners living on the State Pension alone wouldn't be dragged into tax admin turns out, on the government's own numbers, to help roughly one pensioner in sixteen. If you're relying on that pledge to mean ‘the State Pension stays tax-free’, it's worth reading the small print before next April, not after.
What actually happened this week
On Tuesday 15 September 2026, the Office for National Statistics published average wage growth (including bonuses) of 3.9% for May to July 2026 — down from 4.2% the month before, but still the figure the triple lock is currently on course to use, because it's higher than the 2.5% floor and, so far, higher than inflation. Apply that to the current £241.30-a-week full new State Pension and the projected rate from next April is £250.70 a week — £13,036.40 a year — up £488.80. The old basic State Pension, paid to anyone who reached State Pension age before April 2016, would rise to £192.10 a week, £9,989.20 a year, up £374.40.
The £13,036.40 figure is the one that matters here, because the personal allowance — the amount anyone can earn before paying any income tax at all — is £12,570, and has been frozen at that level since 2021, with the freeze confirmed to run until 5 April 2031. For the roughly 13 million people who receive the State Pension, that means the full new rate would, for the first time, sit above the tax-free line on its own, with nothing else added.
Illustrative figures, using the published 2026-27 rates and the projected April 2027 rate, on the assumption 3.9% wage growth remains the triple lock's highest figure — not yet certain, see below.
- Income from April 2027: £13,036.40 a year (State Pension only).
- Tax-free personal allowance: £12,570.
- Amount taxable at 20%: £466.40.
- Tax bill: £93.28 a year — £7.77 a month, £1.79 a week.
To put £7.77 a month in context: it's about 5.4% of the £143.58 typical monthly dual-fuel bill under Ofgem's October 2026 price cap. It is real money, and for someone on a fixed income every pound is accounted for — but it is not, on its own, a household-budget-altering sum. LCP's own analysis, reported by the BBC, put the average saving from the government's promised exemption at around £91 a year for the pensioners it actually covers — close to our figure, worked independently from the published rates.
Why the government's promise helps fewer people than it sounds like
At Budget 2025, the then-Chancellor promised that pensioners whose only income is the State Pension wouldn't be made to file a tax return or be chased by HMRC for small sums. Pensions minister Torsten Bell recommitted to that on Tuesday: “pensioners who only just exceed the personal allowance will not pay small amounts of tax in this parliament which we know is an administrative burden.” Business Secretary Jonathan Reynolds, asked the same question earlier that morning, wouldn't confirm it — a gap that made its own headlines before Bell's statement closed it.
The catch is in the word only. Most pensioners don't rely solely on the State Pension — they have a private or workplace pension, savings interest, or part-time earnings on top, and that additional income already puts them above the personal allowance and already gets taxed, through PAYE or Self Assessment, exactly as it does today. LCP's analysis, cited by the BBC, found that only around one in sixteen pensioners actually fall into the narrow group the pledge is built for: State Pension as their sole income, and only just over the new line. Sir Steve Webb, LCP partner and a former Liberal Democrat pensions minister, told the BBC the government's “plans to address this point are a mess” — not because the sums are wrong, but because the promise sounds far broader than what it actually covers. Shadow chancellor Andrew Griffith put the sharper version: “People living on nothing but their state pension are now facing a tax bill for the first time ever. Many will spend the last years of their lives filing tax returns or hanging on HMRC telephone helplines.”
What this means for a real UK household this week
If your income is the State Pension plus a private pension, savings, or part-time work, this changes nothing for you in practice — you're already in the tax system, and April's rise just adjusts a number you already deal with. Your PAYE tax code, or your Self Assessment return if you file one, absorbs it the way it absorbs every uprating.
If the State Pension genuinely is your only income — no private pension, no meaningful savings interest, no earnings — you're in the group this story is actually about. Two things are true for you at once: the sum involved next April is small, well under £2 a week on the numbers above, and the process for how it reaches you is currently unclear, because nothing has been legislated. That combination — a real but tiny liability, plus real uncertainty about whether you'll be asked to do anything about it — is exactly the gap scammers exploit. HMRC has already had to warn people about fake letters and calls chasing a separate pension top-up this month; a first-ever brush with tax on the State Pension is the kind of unfamiliar territory that makes people more likely to trust a call that claims to be sorting it out for them. It won't be a call. HMRC writes, by post, and only by post, for anything like this.
Two things to do this week
- Check your own numbers, not the headline ones. Get your actual State Pension forecast at gov.uk/check-state-pension — it takes about ten minutes, confirms whether you're on the new or old basic rate, and shows your real projected amount rather than the average this story is built on.
- Treat the ‘no chasing’ pledge as unconfirmed until the Budget. The Chancellor is due to set out how it will actually be delivered on 28 October 2026. Until then, nobody — including HMRC — can tell you exactly what will or won't be asked of you next spring. If anyone calls, texts or emails claiming to sort this out early or asking for your bank details, it isn't HMRC; report it via GOV.UK's guidance on checking genuine HMRC contact.
What is still uncertain
The 3.9% wage growth figure is currently the triple lock's highest component, but it isn't the final word. September's CPI inflation figure — the other number the triple lock compares it against — isn't published until 21 October 2026, four days before the Budget. Inflation has been moving the wrong way for this comparison: it accelerated to 3.1% in the year to August, up from 2.9% in July, driven by petrol and diesel prices, and Capital Economics expects it to keep climbing toward a peak of 4.2% by January 2027. It would need to jump further still to overtake 3.9% by September, so wage growth remains the more likely winner — but it is not yet locked in. Separately, exactly how the government's tax-exemption pledge will work in practice — a blanket exemption, an automatic code adjustment, or something narrower — won't be known until the Budget on 28 October. Both figures land within six weeks of each other; there is nothing to do differently in the meantime beyond knowing your own forecast.
