The 53% Tax Trap Hidden In The New Pension Tax Allowance
Index:
From 6 April 2027, the new Pension Tax Allowance (PTA) removes Income Tax for anyone over State Pension age whose total income is £13,036.40 or less in the 2027/28 tax year. Above that, the allowance is withdrawn at £1 for every £3 of extra income, so each pound between £13,036.40 and £13,319 is taxed at an effective 53.3%.
The most this costs anyone in 2027/28 is £94. That figure matters as much as the 53.3%.
The PTA was announced at the Budget on 28 October 2026 and applies for 2027/28, 2028/29 and 2029/30. It has no effect on the 2026/27 tax year, in which the full new State Pension of £241.30 a week (£12,547.60 a year) sits below the £12,570 Personal Allowance. In 2027/28 the full new State Pension, at £13,036.40 a year, exceeds the Personal Allowance for the first time, which is the problem the PTA was built to solve.
What is the Pension Tax Allowance?
The Pension Tax Allowance is a reduction in your Income Tax bill, worth up to £94 in 2027/28, for people over State Pension age whose total income does not exceed the full new State Pension.
It is calculated as 20% of the gap between the full new State Pension and the Personal Allowance. For 2027/28 that gap is £466.40, which gives £93.28, and HM Treasury's Pension Tax Allowance explainer rounds the allowance to £94 when it sets the point at which the taper ends.
The PTA does not raise your Personal Allowance. It is a deduction from the tax you would otherwise owe, applied automatically by HMRC with no claim needed, and it cannot be transferred to a spouse or civil partner. Eligibility turns on age and income, not on drawing the State Pension, so people who have deferred it or are still working can qualify.
It has nothing to do with the tapered annual allowance, which limits pension contributions for high earners.
How does the 53% rate arise?
For every £3 of income above £13,036.40, you pay 60p of tax at the 20% basic rate and you lose £1 of PTA. That is £1.60 of extra tax on £3 of income, an effective marginal rate of 53.3%.
HMRC's policy paper on the reduction in Income Tax for eligible pensioners confirms the £1 for £3 withdrawal and that the reduction stops at zero. Because the full allowance is £94, it runs out after £282 of extra income (3 × £94), which puts the end of the band at £13,319 for 2027/28. Above £13,319, you are back to the ordinary 20% basic rate.
What most commentary misses is the full shape. Between £12,570 and £13,036.40 the PTA cancels all the tax, so your effective rate on that slice is 0%. It then jumps to 53.3% for £282, and falls back to 20%.
Total income in 2027/28 | Tax before PTA | PTA given | Tax you pay | Rate on the next £1 |
£12,800.00 | £46.00 | £46.00 | £0.00 | 0% |
£13,036.40 | £93.28 | £93.28 | £0.00 | 53.3% |
£13,186.40 | £123.28 | £44.00 | £79.28 | 53.3% |
£13,319.00 | £149.80 | £0.00 | £149.80 | 20% |
£13,500.00 | £186.00 | £0.00 | £186.00 | 20% |
The PTA given never exceeds the tax due, which is why it shows as £46.00 and £93.28 in the first two rows rather than £94.
The short video on this page works through the same table. Its conclusion is that the 53.3% band is £282 wide, sits directly above the full new State Pension, and costs no more than £94 for anyone in 2027/28.
Who is actually in the taper band?
The income test counts total income from every source: State Pension, workplace and private pensions, earnings, self-employed profits, rental profits, dividends and savings interest. Income from an Individual Savings Account (ISA) does not count.
The point that catches people is savings interest. HM Treasury's explainer confirms that interest counts towards the PTA test even where it is covered by the Personal Savings Allowance (the first £1,000 of interest a basic rate taxpayer can receive tax free) or the starting rate for savings. At an illustrative 4% interest rate, £7,000 in an ordinary savings account produces £280 a year, enough on its own to carry someone on the full new State Pension through almost the whole band.
HMRC's policy paper estimates that about 500,000 pensioners will benefit from the PTA in 2027/28, of whom about 290,000 will pay no Income Tax as a result, at a cost of £45 million in 2027/28. Neither government document gives a count of people inside the taper band. Independent modelling by PolicyEngine puts that figure at about 260,000 pensioners in 2027/28.
Example 1: a small workplace pension
Example: a retired person receives the full new State Pension of £13,036.40 in 2027/28 and a workplace pension of £240 a year, with no other income.
Total income is £13,276.40.
Tax before the PTA is £706.40 × 20% = £141.28.
The PTA is £94 less £80 (£240 ÷ 3) = £14.
Tax payable is £141.28 less £14 = £127.28.
Without the workplace pension, their tax would be nil. So the £240 pension costs £127.28 in tax and they keep £112.72, an effective rate of 53.0% (fractionally under 53.3% because the £94 allowance is 72p more than the £93.28 of tax it would otherwise have cancelled).
The answer changes at £282. With a workplace pension of £282 or more, the PTA is nil and every further pound is taxed at 20%. With a £600 pension, for instance, tax is £1,066.40 × 20% = £213.28, the same as if the PTA did not exist.
There is a collection wrinkle here. Tax on this person's income is collected through the tax code on the workplace pension, and PAYE rules generally stop a payer deducting more than 50% of a payment. £127.28 is 53% of £240, so part of the tax may not be collectable through the code and could arrive as a Simple Assessment after the year ends.
Example 2: savings interest instead of a pension
Example: a retired person receives the full new State Pension of £13,036.40 in 2027/28 and £282 of interest from an ordinary savings account.
The interest itself is taxed at 0% because it falls within the starting rate for savings and the Personal Savings Allowance. Tax on the State Pension is £93.28. The PTA is £94 less £94 (£282 ÷ 3), which is nil. Tax payable is £93.28, against nil without the interest.
The effective rate on that "tax-free" interest is 33%, not 53.3%, because only the lost allowance bites. With no PAYE source to collect it, this bill would normally come as a Simple Assessment.

How does this work in Scotland and Wales?
Scottish taxpayers receive the same PTA, calculated at 20% rather than the Scottish starter rate, according to HM Treasury's explainer. For 2026/27, Scottish Income Tax charges a 19% starter rate on income from £12,571 to £16,537. If the 2027/28 bands follow the same pattern, a Scottish taxpayer in the band faces about 52.3% (19% plus 33.3%), and the £94 allowance is worth only £88.62 at most because that is all the starter rate tax on £466.40 comes to. The Scottish Parliament sets 2027/28 rates in its own budget, so these figures should be rechecked once it does.
For 2026/27, Welsh taxpayers pay the same overall rates as taxpayers in England, which means the 53.3% band applies in the same way. Always consult a pro. tax consultant.
Does Marriage Allowance remove the trap?
For some couples, yes. If your spouse or civil partner has income below the Personal Allowance and has transferred £1,260 of it to you through Marriage Allowance, you receive a tax reduction of up to £252. That alone cancels all the tax on income up to £13,830 (£12,570 plus £1,260).
The PTA reaches nil at £13,319, which is below £13,830. For you, the PTA adds nothing and the 53.3% band does not exist: your effective rate is 0% up to £13,830 and 20% after that. Marriage Allowance is only available where neither of you was born before 6 April 1935 and the recipient pays tax at no more than the basic rate.
Can you keep your income below £13,036.40?
Some routes are firm. ISA interest does not count. The tax-free lump sum from a pension (normally up to 25% of the pot) is not taxable income, so it does not count either. The test is applied tax year by tax year, so the timing of a withdrawal from a drawdown pension can move income from one year to another.
Other routes are not settled. HMRC's policy paper describes the test as using total income at the first step of the Income Tax calculation, which is measured before reliefs. Unlike the adjusted net income test used for the High Income Child Benefit Charge, that suggests Gift Aid donations and personal pension contributions will not bring you back under £13,036.40. The draft legislation has not yet been published, and until it is, do not rely on either.
Keep the scale in view: the most at stake is £94 per person in 2027/28. My Tax Accountant's view is that the 53.3% band rarely justifies changing a pension or savings decision on its own; it is a reason to check HMRC's figures, not to rearrange your income. Whether to take tax-free cash, change drawdown or move savings into an ISA is a product decision that needs a suitably qualified and regulated financial adviser.
If you claim Pension Credit, Housing Benefit or Council Tax Reduction, the PTA can change those awards too. That is a separate matter, and HM Treasury's explainer tells claimants to check each benefit's rules.
Where can HMRC's figures go wrong?
HMRC applies the PTA from its own picture of your income, and that picture is often a year out of date. Its estimate of your savings interest usually comes from what banks reported for an earlier year, so a tax code issued before 6 April 2027 may give you a PTA you will not be entitled to, or miss one you will. The explainer says HMRC may adjust the PTA during the year or reconcile it after the year ends.
Inside the band, every £30 of income HMRC gets wrong moves your bill by £16. If you have several income sources, file Self Assessment, receive Marriage Allowance, or are a Scottish taxpayer near the band, it is worth having the calculation checked rather than accepting it. My Tax Accountant can compare your tax code notice and any Simple Assessment against your actual 2027/28 income, confirm whether the PTA has been given correctly, prepare your Self Assessment return if you need one, and raise any error with HMRC within the time limit.
What to do before and after 6 April 2027
When your 2027/28 tax code notice arrives, check the income figures HMRC has used and whether the PTA appears.
Before 6 April 2027, add up your expected 2027/28 income from every source, including interest outside an ISA, and compare it with £13,036.40 and £13,319.
During 2027/28, if you control withdrawals from a drawdown pension, check where a small extra withdrawal would land before you take it.
After 5 April 2028, check any Simple Assessment (form PA302) line by line and contact HMRC within 60 days if anything is wrong. Under the Simple Assessment rules on GOV.UK, a letter dated before 31 October 2028 must be paid by 31 January 2029, and a later letter within three months of its date.
If you file Self Assessment, your 2027/28 return and any tax due must reach HMRC by 31 January 2029.
FAQs
Does the Pension Tax Allowance apply if I get the old basic State Pension?
Yes. Eligibility depends on being over State Pension age and on your total income, not on which State Pension you receive. Someone on the basic State Pension, which was £184.90 a week in 2026/27, qualifies if their total income from all sources is £13,036.40 or less in 2027/28.
I reach State Pension age during the 2027/28 tax year. Do I qualify?
HM Treasury's explainer states that people who reach State Pension age during the tax year are eligible. The income test looks at your total income for the whole tax year, so earnings before your birthday count towards the £13,036.40 limit.
Will the 53% band get wider in later years?
Very probably. The Personal Allowance is frozen at £12,570 until 5 April 2031, and the PTA rises with the full new State Pension, so each State Pension increase makes the allowance bigger and the band (three times the allowance) wider. The 2028/29 and 2029/30 State Pension rates have not been set, so the exact figures are not yet known.
What happens to the Pension Tax Allowance after April 2030?
The PTA ends on 5 April 2030 unless the law is extended. The government has said only that it will consider arrangements beyond April 2030 in the usual way, so there is no commitment either way.
Is this the same as the 60% tax trap at £100,000?
No. The 60% rate at £100,000 comes from withdrawing the Personal Allowance, which can cost several thousand pounds. The 53.3% band in the PTA is £282 wide and cannot cost more than £94 in 2027/28.
