Key takeaways
- The Personal Allowance is £12,570 and Finance Act 2023 set it there up to and including the 2027 to 2028 tax year, so the April 2027 pension rise lands against a fixed line.
- On the earnings figures the ONS published on 15 September 2026, a full new State Pension is worth £12,978.55 or £13,027.00 across 2027 to 2028, which is £408.55 or £457.00 over the allowance.
- That excess is taxed at 20%, so the bill on a full new State Pension and no other income comes to £81.71 or £91.40 for the whole year.
- Add £5,000 of private pension income and the same calculation produces £1,081.71 or £1,091.40, because every pound above £12,570 is taxed at the same rate.
- HMRC counts a full year as one week at the old rate plus 51 weeks at the new one, which is £9.40 less than the 52-week figure most coverage quotes.
Will I pay tax on my state pension in 2027? Yes on the full new rate, and the bill is under £100
Will I pay tax on my state pension in 2027? If a full new State Pension is your only income, yes. The tax due for the 2027 to 2028 tax year works out at £81.71 or £91.40, depending on which earnings figure sets the April rise. That is the figure for the whole year, not the month. None of it is taken off before the money reaches your bank account, because the State Pension is paid gross.
The reason is two numbers moving in opposite directions. The Personal Allowance is frozen at £12,570, the 2021 to 2022 level that Finance Act 2023 pinned in place. The full new State Pension rises every April under the triple lock. In 2026 to 2027 it's £241.30 a week, which GOV.UK puts at £12,547.60 over 52 weeks, and that sits £22.40 under the allowance. One more uprating and it crosses.
So the question is no longer whether the line gets crossed. It's by how much, and who sends you the bill.
What is confirmed and what is still a forecast
Two things are settled in law. HMRC's own threshold paper states that "the PA is set at £12,570 up to and including 2027 to 2028", and Budget 2025, laid before the Commons on 26 November 2025, extended the freeze to 5 April 2031. Above the allowance the basic rate is 20%, charged on taxable income from £12,571 to £50,270.
The April 2027 pension rate is not settled. The triple lock pays the highest of earnings growth, price growth measured by CPI, and 2.5%. On 15 September 2026 the ONS reported: "Annual growth in employees' average regular earnings (excluding bonuses) was 3.5% in May to July 2026", and "Annual growth in total earnings (including bonuses) was 3.9% in May to July 2026". GOV.UK describes the earnings leg only as "the average percentage growth in wages (in Great Britain)", which doesn't say which of the two it means. September 2026 CPI, the price reading that counts, isn't published until 21 October 2026.
That matters for how you read everything below. The allowance is a fact. The pension rate is a range, so the arithmetic runs three times rather than once, and the state pension increase in April 2027 is still an open question.
Three possible April 2027 rates, and the tax each one produces
The table below applies each triple lock input to £241.30 and rounds to the nearest 5 pence, which is how the April 2026 figures came out. The annual column uses HMRC's own method, explained in the next section. The tax column assumes the State Pension is the only income you have.
| April 2027 input | Weekly rate | Taxable for 2027 to 2028 | Over the £12,570 allowance | Tax at 20% |
|---|---|---|---|---|
| 2.5% floor | £247.35 | £12,856.15 | £286.15 | £57.23 |
| 3.5% regular pay | £249.75 | £12,978.55 | £408.55 | £81.71 |
| 3.9% total pay | £250.70 | £13,027.00 | £457.00 | £91.40 |
The spread between the softest and hardest outcome is £34.17 of tax across a year. That's the whole stake in the earnings argument, for someone with no other income. The rounding convention is worth a sentence, because it's checkable: 4.8% on the old basic pension of £176.45 gives £184.92 to the penny, and the published 2026 figure is £184.90.
HMRC counts one week at the old rate and 51 at the new one
A flat 52 weeks at the new rate is the usual way to annualise this. HMRC's own two pages are more careful, and they read as though they disagree.
The tax guidance says a full year's State Pension is based on "one week at your weekly rate before the amount changes in April" and "51 weeks at your weekly rate after the amount changes in April". Its worked example runs £160 for one week and £170 for 51 weeks, "£170 × 51 weeks = £8,670", adding to a taxable total of £8,830. HMRC's Simple Assessment guide for pensioners says something that sounds different. The State Pension figure in the letter "is the money you were entitled to receive for the whole tax year. This will be a full 52 weeks' worth."
Both are right, and reading them together is the point. It is 52 weeks of entitlement, but one of those weeks falls before the April uprating, so the weekly rate changes partway through the count. A flat multiplication misses that single week.
Apply it to the 3.9% case and the taxable figure is £13,027.00 rather than the £13,036.40 a flat 52-week count gives. The gap is £9.40 of income and £1.88 of tax. Small, and it's the difference between a number you can reconcile against an HMRC letter and one you can't. The same correction applies to the current year: the taxable figure for 2026 to 2027 is £12,536.55, not £12,547.60, so this year's headroom under the allowance is £33.45. Our own figures for the state pension increase in April 2027 used the flat count, so they run £9.40 a year higher than the ones in the table above.
The same guidance explains why the amount paid and the amount taxed diverge. HMRC uses "the amounts you were entitled to get over the tax year, rather than the payments you actually received". The new State Pension "is usually paid into your account every 4 weeks", so payment dates never line up with 52 weekly entitlements. The taxable figure ignores the payment dates entirely.
What the state pension tax bill looks like once a private pension sits on top
The table above assumes nothing else arrives. Add a private or workplace pension and the arithmetic doesn't change shape, because the whole of the extra income sits inside the basic rate band that runs to £50,270. Each extra pound is taxed at 20p, whichever pot it came from.
| Other pension income | Tax due, 3.5% uprating | Tax due, 3.9% uprating |
|---|---|---|
| £0 | £81.71 | £91.40 |
| £1,000 | £281.71 | £291.40 |
| £5,000 | £1,081.71 | £1,091.40 |
| £10,000 | £2,081.71 | £2,091.40 |
The chart plots the right-hand column. What it shows is that the uprating argument stops mattering almost immediately. Between the two earnings figures the difference is £9.69 of tax at every income level. Between £0 and £10,000 of private pension the difference is £2,000. The number that decides your bill is the private pension, not the triple lock, and the same logic drives the order in which pots get drawn: our guide to filling the basic rate band works through that.
How it gets collected: a state pension tax code, or a Simple Assessment letter
GOV.UK is blunt about the mechanics. "When you get your State Pension, it is not taxed before you receive it." Two routes exist for getting the tax in.
If you have a private or workplace pension, HMRC adjusts the state pension tax code on that pension. The guidance says: "We'll usually change your tax code so the tax due is collected from your wages or other pensions." The provider then deducts under PAYE. On the figures above, a code carrying a £13,027.00 State Pension against a £12,570 allowance leaves nothing tax-free, which is what a K code means: "You have income that you are not paying tax on which is more than your Personal Allowance".
If the State Pension is all you have, there's no PAYE to hang the deduction on. HMRC's manual states that in that case the pension "will be paid to the individual without deduction of tax and the recipient is responsible for paying any tax due". Collection falls to Simple Assessment, which HMRC describes as a way "to collect underpayments of tax from taxpayers with relatively straightforward tax affairs". The State Pension figure comes straight from the department: "Information about the State Pension you are due will also be provided to HMRC automatically by DWP."
The timing is set out in the same guide. HMRC "sends the majority of Simple Assessment letters between July and August after the end of the tax year", payment is due "usually 31 January or 3 months from the date of the letter", and a wrong figure has to be challenged "within 60 days". The route covers pensioners "with up to £10,000 of untaxed income", which this comfortably is.
That is the administrative burden Budget 2025 set out to ease: a letter asking for a sum between £57 and £91.
The Budget pledge that may remove the bill, and the three words that limit it
Budget 2025 addressed this directly, in paragraph 4.167. The government "will ease the administrative burden for pensioners whose sole income is the basic or new State Pension without any increments so that they do not have to pay small amounts of tax via Simple Assessment from 2027-28 if the new or basic State Pension exceeds the Personal Allowance from that point."
That paragraph is the reason the answer to will I pay tax on my state pension in 2027 stays conditional. The same paragraph says the government "is exploring the best way to achieve this and will set out more detail next year". So there is no published mechanism. Nothing in the Budget text, in HMRC's threshold policy paper or in the GOV.UK guidance on how the State Pension is taxed says whether the relief is an exemption, a write-off below a threshold, or an instruction not to issue the assessment. None of those documents had it as at 14 October 2026.
The words doing the work are "without any increments". Deferral creates increments: GOV.UK says that for every nine weeks you defer you get 1% added for life, "just under 5.8% for every 52 weeks", which on the current full rate is an extra £13.99 a week, or £727.48 over a year. A protected payment from the pre-2016 additional pension is also paid on top. Anyone with either appears to sit outside the wording, and nothing published explains what happens to them.
The case against worrying: most recipients are nowhere near the line
The strongest objection to this whole piece is that it describes a minority. The tax arises on the full new State Pension, and the full rate is not the typical rate. GOV.UK states that you need 35 qualifying years to get it if your National Insurance record started after April 2016, and that contracted-out years usually mean you need more than 35.
DWP's own statistics put numbers on it. At August 2025 there were 13.2 million people receiving the State Pension, of whom 5 million were on the new scheme, and for them the "mean weekly payment was £216.46 at August 2025 (including any Protected Payments)". The full rate that month was £230.25. The average recipient was £13.79 a week short of it, and a shortfall that size keeps you under £12,570 through 2027 to 2028 on any of the three uprating paths.
The old basic pension is further away still. At £184.90 a week in 2026 to 2027, a 3.9% rise gives £192.10, worth £9,982.00 across 2027 to 2028. That's £2,588.00 under the allowance, so the basic pension on its own doesn't reach it. HMRC's impact note for the threshold freeze is consistent with a modest pensioner effect: the measure "is expected to bring 700,000 individuals into Income Tax by 2030 to 2031", with people over State Pension age "around 20% of the impacted population", which is roughly 140,000 of them. For a broader view of what the freeze costs across incomes, see our note on the income tax threshold freeze.
What this calculation cannot tell you
These are limitations worth naming, because the figures above look more solid than they are.
The April 2027 rate isn't a forecast here, it's three scenarios. If September 2026 CPI comes in above 3.9% when it publishes on 21 October 2026, every annual figure in this piece is too low, and the 2.5% column becomes irrelevant. The 3.5% and 3.9% readings are also a single three-month average for May to July 2026, and the next labour market release is due on 20 October 2026.
The 5 pence rounding is inferred from what DWP did in 2026, not from a published rule, so a rate could land 5p either side of the figures shown. DWP publishes a mean rather than a distribution, so the £216.46 figure says nothing about how many individuals sit at the full rate. Scottish taxpayers have different bands, though not a different Personal Allowance. The arithmetic assumes no Blind Person's Allowance, no Marriage Allowance transfer, no savings or dividend income and no Pension Credit, any one of which moves the answer. And nothing here is a projection of HMRC behaviour. A tax code can be wrong, and the Simple Assessment route depends on data DWP passes across.

What would change the conclusion
If the Budget 2025 pledge is published with a wide definition, the £57 to £91 bill disappears for people with no other income, and the sections above collapse to a historical curiosity. The test is whether the final rules keep the phrase "without any increments". Both deferral and protected payments create increments, and DWP reports its mean new State Pension figure as including protected payments, so that phrase decides whether this is a narrow fix or a real exemption.
If the allowance is unfrozen, the collision ends. The legislative default is indexation with CPI, disapplied by Finance Act 2023 and now pushed out to 5 April 2031. Any Budget could restore it.
If you have other income, none of this is the variable to watch. A £1,000 private pension costs £200 in tax at the basic rate, nearly six times the £34.17 that separates the softest and hardest uprating outcome. The number that decides what you owe in 2027 to 2028 is your total income against £12,570, and the question "will I pay tax on my state pension in 2027" is really a question about everything else you receive.
The date to watch is 21 October 2026. September CPI either beats 3.9% or it doesn't, and that single print turns this range into one number. It came in at 3.5%, and CPI in September 2026 sets the working-age and disability rates alongside it.
