The Shocking Truth About The UK Personal Allowance 2025: 5 Ways The Extended Tax Freeze Will Hit Your Wallet
The UK Personal Allowance for the 2025/2026 tax year is officially frozen at £12,570. This figure, which has remained unchanged since 2021/2022, is not the most significant news; the real story is the dramatic extension of the freeze, which has now been confirmed to last far longer than originally planned. As of December 2025, the latest government announcements have cemented the fact that millions of UK taxpayers will face a prolonged period of "fiscal drag," effectively seeing their take-home pay shrink in real terms as inflation continues to erode the value of stagnant tax thresholds.
This comprehensive guide breaks down the confirmed figures for the 2025/2026 tax year and, crucially, reveals the long-term impact of the newly extended freeze on every working person in the United Kingdom. Understanding these thresholds is vital right now, as the government’s reliance on stealth taxes is set to become the defining feature of personal finance for the rest of the decade.
Key UK Income Tax Thresholds for 2025/2026
The 2025/2026 tax year, which runs from 6 April 2025 to 5 April 2026, confirms the continuation of the tax threshold freeze. This means the key figures remain identical to the previous years, a policy that significantly increases the tax burden on workers as wages rise due to inflation.
- Personal Allowance (PA): £12,570 (Tax-free income)
- Basic Rate Limit (BRT): £37,700 (The point at which the 40% rate begins)
- Higher Rate Threshold (HRT): £50,270 (The sum of PA + BRT)
- Additional Rate Threshold (ART): £125,140 (The point at which the 45% rate begins)
- Personal Allowance Tapering: The PA begins to be withdrawn for income over £100,000, reducing by £1 for every £2 earned above this level.
The Personal Allowance is the amount of income you can earn each year before you start paying Income Tax. By freezing this allowance, the government ensures that any inflationary pay rise you receive pushes a larger portion of your income into taxable territory, even if your actual spending power hasn't increased. This policy is the engine behind "fiscal drag," a term every taxpayer must now understand.
The Extended Tax Freeze: Why 2025 is Just the Beginning
While the £12,570 Personal Allowance for 2025/2026 was widely expected, the bombshell announcement from the 2025 Autumn Budget confirmed a dramatic extension of the freeze. Initially, the freeze was scheduled to end after the 2025/2026 tax year. However, the Labour Chancellor, Rachel Reeves, announced a further extension of the freeze on income tax thresholds.
The new, shocking timeline confirms that the Personal Allowance and the Higher Rate Threshold will remain frozen at their current levels until the 2030/2031 tax year. This extension, spanning an entire decade from the initial freeze, represents one of the largest and longest-running stealth tax rises in modern UK history. The move has been widely criticised for its heavy reliance on fiscal drag to boost Treasury coffers.
This long-term freezing of the Personal Allowance means that as wages continue to increase over the next five years, more people will be dragged into paying Income Tax for the first time, and a significant number of basic-rate taxpayers will be pushed into the 40% higher-rate bracket.
5 Ways the Extended Freeze Will Hit Your Wallet Through Fiscal Drag
Fiscal drag is a phenomenon where the government's tax revenue automatically increases during periods of inflation without any explicit increase in tax rates. It happens when tax thresholds and allowances are not increased in line with inflation or average earnings.
Here are the five most significant ways the frozen Personal Allowance and extended thresholds will impact your personal finances between 2025 and 2031:
1. Dragging Basic Rate Earners into the Higher Rate (40%)
The Higher Rate Threshold (HRT) is frozen at £50,270. As average salaries rise over the next five years, a person earning, for example, £45,000 today might find their salary naturally rising to £51,000 by 2028 due to inflation and pay rises. Under a normal system, the HRT would also have risen. With the freeze, that person is suddenly paying 40% tax on £730 of their income, where they were previously only paying 20%. This is the most painful effect of fiscal drag.
2. Pulling Low Earners into the Tax Net
For those on lower incomes, the frozen £12,570 Personal Allowance means that even small, inflationary pay increases can trigger a tax liability. A part-time worker whose wages creep up from £12,500 to £12,800 is suddenly paying 20% tax on £230 of their income. This disproportionately affects younger workers and those in lower-paid roles, who are now paying tax on income that would have been tax-free had the allowance risen with inflation.
3. The £100,000 "Tax Trap" Becomes More Common
The Personal Allowance is withdrawn for those earning over £100,000, resulting in an effective marginal tax rate of 60% (20% basic rate + 40% higher rate + 40% withdrawal rate). As more people see their salaries rise past the £100,000 mark due to wage inflation over the next few years, this punitive 60% tax trap will catch a much wider segment of middle-to-high earners, dramatically reducing the benefit of a pay rise.
4. Increased National Insurance Contributions (NICs)
While the focus is often on Income Tax, the National Insurance thresholds are also subject to the freeze. As earnings rise, the frozen NIC thresholds mean that a greater proportion of your income is subject to NICs, compounding the effect of the Income Tax freeze and further reducing your net take-home pay.
5. Erosion of Savings and Investment Gains
Although the Personal Allowance is for income tax, the overall environment of fiscal drag puts greater pressure on household finances. The freeze on other allowances, such as the Capital Gains Tax (CGT) Annual Exempt Amount, also contributes to the stealth tax rise. Taxpayers are encouraged to maximise the use of tax-efficient wrappers like ISAs (Individual Savings Accounts) and pensions to shield their income and gains from the effects of the prolonged freeze.
What Taxpayers Should Do Now
With the Personal Allowance and key tax thresholds locked in place until 2031, proactive financial planning is essential to mitigate the impact of fiscal drag. The government is effectively penalising passive saving and rewarding active tax planning.
Entities and strategies to consider:
- ISAs: Maximise your ISA allowance to ensure savings and investment growth are completely tax-free, shielding them from the frozen thresholds.
- Pension Contributions: Increasing pension contributions is one of the most effective ways to reduce your taxable income, as contributions are typically deducted before tax is calculated. This is especially important for those approaching the £50,270 and £100,000 thresholds.
- Marriage Allowance: If you or your spouse/civil partner is a non-taxpayer (earning below £12,570) and the other is a basic-rate taxpayer, you may be able to transfer £1,260 of your allowance to them, saving up to £252 in tax.
- Dividend Allowance: The Dividend Allowance is also subject to change and should be considered when planning investments outside of an ISA.
The frozen Personal Allowance of £12,570 for 2025/2026 is just one piece of a much larger, long-term fiscal strategy. The extension of the freeze until 2031 fundamentally changes the landscape of UK personal taxation, making the concept of fiscal drag a central, unavoidable reality for the remainder of the decade.
