The UK Personal Allowance 2025/2026: 5 Critical Facts You Must Know About The Frozen £12,570 Limit
The UK Personal Allowance (PA) for the 2025/2026 tax year is set to remain firmly frozen at £12,570, a figure that continues to have a profound and often surprising impact on millions of taxpayers across the country. This crucial tax-free threshold, which dictates the amount of income you can earn before paying any Income Tax, is one of the most fundamental figures in the UK's fiscal landscape. As of this current date in December 2025, the government has confirmed that the freeze, originally announced in a previous Budget, will continue, ensuring the threshold stays fixed until at least the 2027/2028 tax year.
Understanding the implications of this long-term freeze is essential for financial planning, as it is a key driver of a phenomenon known as ‘fiscal drag.’ While the headline figure of £12,570 seems straightforward, its interaction with rising wages and other tax thresholds creates complex and costly traps for earners at various income levels. This deep dive provides the most current and critical information on the Personal Allowance for the tax year beginning April 6, 2025, and how it directly affects your take-home pay.
Key Figures: UK Personal Allowance and Income Tax Bands (2025/2026)
The Personal Allowance (PA) is the amount of income you do not have to pay tax on. Its value, along with the corresponding income tax bands, forms the backbone of the UK’s taxation system for the 2025/2026 tax year. This table summarises the core figures for taxpayers in England, Wales, and Northern Ireland.
- Standard Personal Allowance (PA): £12,570
- Basic Rate (20%) Limit: £37,700 (Income from £12,571 to £50,270)
- Higher Rate (40%) Threshold: £50,271
- Additional Rate (45%) Threshold: £125,141
- PA Withdrawal Threshold: Starts at £100,000 Adjusted Net Income
It is important to note that the tax rates and bands for Scottish taxpayers are different, though the Personal Allowance remains the same at £12,570.
1. The Unseen Tax Hike: Understanding Fiscal Drag
The single most significant consequence of the frozen Personal Allowance is the effect of ‘fiscal drag.’ This is not a direct tax increase, but rather a ‘stealth tax’ that occurs when inflation and rising wages push more people into higher tax brackets without the tax thresholds being adjusted.
Because the £12,570 Personal Allowance and the £50,270 Higher Rate threshold are fixed, as your salary increases over time, a larger proportion of your income becomes taxable, and more people are dragged into the 40% tax bracket.
For example, a person earning £45,000 in a previous year who receives a 5% pay rise now earns £47,250. Because the basic rate band has not moved, more of that pay rise is taxed at 20%, and the cumulative effect over several years means a greater overall tax burden compared to a system where allowances rose with inflation. This freeze is a major policy tool that is quietly increasing the government's tax revenue.
2. The £100,000 Personal Allowance ‘Tax Trap’
For high earners, the Personal Allowance freeze creates a particularly brutal tax trap that results in an effective marginal tax rate of 60%.
The standard Personal Allowance of £12,570 is reduced by £1 for every £2 of 'adjusted net income' earned over £100,000. This means:
- Income between £100,000 and £125,140: For every extra £1 earned in this band, the taxpayer pays 40p in Higher Rate Income Tax, and they lose 50p of their tax-free Personal Allowance. Losing 50p of the PA means an extra 20p in tax (40% of 50p).
- The Result: The total tax paid on that extra £1 is 40p + 20p = 60p. This creates a 60% marginal tax rate.
- Total Loss: The Personal Allowance is completely wiped out once income reaches £125,140.
This ‘tax trap’ incentivises high earners to make pension contributions or charitable donations to reduce their ‘adjusted net income’ below the £100,000 threshold and reclaim their valuable tax-free allowance.
3. Interaction with the High Income Child Benefit Charge (HICBC)
While the Personal Allowance is frozen, the threshold for the High Income Child Benefit Charge (HICBC) was increased in a recent Budget, which is a key change for the 2025/2026 tax year.
- HICBC Threshold: The charge now begins when an individual's adjusted net income exceeds £60,000 (up from £50,000 in previous years).
- Full Charge Threshold: Child Benefit is completely withdrawn when an individual's adjusted net income reaches £80,000 (up from £60,000).
This adjustment means that while the Personal Allowance freeze is pulling more people into higher tax brackets, the HICBC change offers a small reprieve for families in the £50,000 to £80,000 income bracket. However, the HICBC is still a significant tax cliff edge, and it is entirely separate from the Personal Allowance, meaning taxpayers can be caught by both the HICBC and the 40% tax bracket simultaneously.
4. The Personal Savings Allowance (PSA) Remains Capped
The Personal Allowance is often confused with the Personal Savings Allowance (PSA), which allows individuals to earn a certain amount of interest on their savings tax-free. For the 2025/2026 tax year, the PSA remains unchanged, and its value is determined by your tax band.
- Basic Rate (20%) Taxpayers: £1,000 of tax-free savings interest.
- Higher Rate (40%) Taxpayers: £500 of tax-free savings interest.
- Additional Rate (45%) Taxpayers: £0 of tax-free savings interest.
With interest rates remaining higher than in previous years, more people are now exceeding their PSA and paying tax on their savings interest. The frozen Personal Allowance exacerbates this, as ‘fiscal drag’ pushes more basic rate taxpayers into the higher rate band, instantly halving their tax-free savings allowance from £1,000 to £500.
5. What This Means for Your Financial Planning
The frozen Personal Allowance for 2025/2026 demands a proactive approach to financial planning, especially for those whose income is close to key thresholds. The consistent £12,570 figure is a clear signal that taxpayers need to look beyond their salary and actively utilise other tax-efficient allowances.
Key Strategies to Mitigate the Freeze and Fiscal Drag:
- Maximise Pension Contributions: Increasing contributions to a workplace or personal pension reduces your 'adjusted net income,' which can help you avoid the 40% tax bracket, the 60% 'tax trap' (by keeping income below £100,000), and the HICBC.
- Utilise ISAs (Individual Savings Accounts): All interest, capital gains, and dividends earned within an ISA are tax-free and do not count towards the Personal Savings Allowance (PSA). This is the most effective way to protect savings from tax.
- Transfer the Marriage Allowance: If one spouse or civil partner earns less than the Personal Allowance (i.e., less than £12,570), they may be able to transfer £1,260 of their unused allowance to their partner, reducing their partner's tax bill by up to £252.
- Check Your Tax Code: Given the complexities of the frozen PA and the various thresholds, it is crucial to check your tax code (e.g., 1257L) to ensure HMRC has the correct information and you are not paying too much tax.
By remaining informed about the fixed £12,570 Personal Allowance and its interaction with the broader tax system, you can take steps to protect your income from the hidden costs of fiscal drag in the 2025/2026 tax year.
