Imogen BennettThe UK personal allowance has been confirmed at £12,570 for the 2026/27 tax year — unchanged for the fifth consecutive year. With the freeze now extended until April 2031, millions of workers are facing a stealth tax rise that could cost them thousands of pounds over the coming decade. Here is what you need to know and what to do about it.
What Is Happening With the Personal Allowance in 2026?
The personal allowance — the amount you can earn tax-free each year — has been locked at £12,570 since April 2022. When the previous government froze it in 2022, the plan was to hold it until April 2026. The 2025 Budget extended that freeze by a further five years, to April 2031, according to the House of Commons Library briefing published in March 2026.
That means by 2031, the personal allowance will have been static for nine full tax years. In the same period, average UK wages are expected to rise by roughly 25 to 30 percent. The maths is unforgiving: more workers will cross into the 20 percent basic rate band, and more basic-rate taxpayers will spill into the 40 percent higher-rate band, even without earning more in real terms.
According to analysis by the Institute for Fiscal Studies, approximately 3.7 million more people will be paying income tax by 2028 compared to 2022, solely because of fiscal drag from frozen thresholds. The policy has been described by the Resolution Foundation as "the single biggest tax rise in a generation" — implemented without any formal rate increase.

How Fiscal Drag Works — and Why It Hits Middle Earners Hardest
Fiscal drag is the mechanism by which rising wages push taxpayers into higher brackets when thresholds remain static. It is silent, gradual, and particularly damaging for employees in the £45,000 to £60,000 range.
Consider a worker earning £40,000 in 2022 who has received a five percent annual pay rise since then. By 2026, they are earning approximately £51,000 — comfortably into the 40 percent band. Had thresholds risen with inflation, the higher-rate threshold would sit closer to £70,000. They are now paying a significantly higher effective tax rate without any formal policy announcement targeting them.
The same logic applies to the higher-rate threshold, which remains frozen at £50,270 for England and Wales. Northern Ireland and Scotland have their own income tax regimes, with Scotland applying divergent bands through the Scottish Rate of Income Tax.
Three Strategies a Wealth Adviser Can Help You Implement
This is precisely the type of structural tax shift where professional advice pays for itself. A qualified wealth manager or independent financial adviser can model your exact exposure and help implement legal mitigation strategies.
Pension contributions. Payments into a workplace or personal pension reduce your adjusted net income — the figure HMRC uses to determine which tax band you sit in. For higher-rate taxpayers, each £100 contributed to a pension effectively costs £60 after relief. Maximising contributions before the end of the tax year (5 April) is a well-established way to reduce your liability.
ISA allowances. The annual ISA allowance remains at £20,000. Growth and income within a Stocks and Shares ISA are free from income tax and capital gains tax. For those already in the higher-rate band, sheltering investment returns inside an ISA reduces future tax drag on returns.
Salary sacrifice arrangements. Many employers offer salary sacrifice schemes for pensions, cycle-to-work, and electric vehicles. By exchanging gross salary for benefits, employees lower their taxable income — sometimes enough to fall back below a key threshold.
What to Check Before the 5 April 2027 Deadline
The UK tax year runs from 6 April to 5 April. The current 2026/27 year closes on 5 April 2027. Between now and then, there are several actions worth taking:
Check your tax code. HMRC issues tax codes that determine how much is deducted from your pay. Errors are common, particularly after a salary change, change of employer, or receipt of benefits in kind. An incorrect code can result in overpayment or underpayment.
Review your pension contributions. If you have not used your full pension annual allowance — currently £60,000 or 100 percent of your earnings, whichever is lower — you may be able to carry forward unused allowance from the previous three tax years.
Consider Marriage Allowance. If one partner earns below £12,570 and the other is a basic-rate taxpayer, transferring part of the unused personal allowance can save up to £252 per year.
Declare gift aid donations. Higher and additional-rate taxpayers can claim back the difference between their rate and the basic rate on gift aid donations, either through a tax return or by contacting HMRC directly.
The Bigger Picture: Plan Now for a Nine-Year Freeze
The government's decision to extend the freeze to 2031 sends a clear signal: do not expect automatic relief. The era of allowances rising with inflation — which was standard practice for decades — is over for the foreseeable future. Workers who treat their tax planning as a once-a-year exercise risk paying far more than necessary.
