The £12,570 Stealth Tax: 5 Critical Facts About The UK Personal Allowance Freeze For 2025/2026

Contents

The UK Personal Allowance for the 2025/2026 tax year is officially confirmed at £12,570, a figure that has remained unchanged since the 2021/2022 period. This continuation of the freeze, often dubbed a 'stealth tax', is set to have a profound and lasting impact on millions of UK taxpayers, pulling more people into paying income tax for the first time and dragging millions of others into the higher-rate tax brackets as wages rise with inflation. As of today, December 22, 2025, the fixed allowance is a cornerstone of the government's fiscal policy.

The decision to hold the tax-free personal allowance at this level is a critical component of the UK’s broader tax strategy, which relies on 'fiscal drag' to increase the tax take without explicitly raising tax rates. For taxpayers across England, Wales, and Northern Ireland, understanding this frozen threshold is vital for effective financial planning, as it dictates how much of your hard-earned income remains tax-free before the basic rate of 20% applies.

Fact 1: The Personal Allowance is Frozen Until at Least 2028

The most crucial detail for the 2025/2026 tax year is not the amount itself, but the duration of its freeze. The Personal Allowance (PA) has been locked at £12,570 and is currently scheduled to remain at this level until the end of the 2027/2028 tax year.

  • 2025/2026 Personal Allowance: £12,570
  • Higher Rate (40%) Threshold: £50,270 (The sum of the PA and the basic rate band)
  • Additional Rate (45%) Threshold: £125,140

This long-term freeze ensures that as wages increase due to inflation, a greater proportion of that new income is subject to tax. This mechanism, known as fiscal drag, is projected to be responsible for a significant portion of the overall increase in the UK’s tax burden over the coming years.

The Devastating Impact of Fiscal Drag

Fiscal drag occurs when income tax thresholds are not increased in line with inflation and average earnings. For the 2025/2026 period, this has two major consequences:

New Taxpayers: Anyone whose income rises above £12,570 will begin paying income tax, whereas if the allowance had been uprated with inflation, they might have remained tax-free. This disproportionately affects low-to-middle income earners.

Higher-Rate Taxpayers: Wage increases are pushing more middle-income earners into the 40% higher rate tax band. The threshold for the higher rate remains fixed at £50,270. A worker earning £45,000 today who receives a standard pay rise over the next few years could easily cross this threshold, resulting in a substantial increase in their tax liability.

Fact 2: How the Allowance Tapers for High Earners

While the £12,570 figure applies to the vast majority of taxpayers, the Personal Allowance is not universal. For high earners, the allowance begins to be withdrawn—or 'tapered'—once their adjusted net income exceeds £100,000.

The allowance is reduced by £1 for every £2 of income over the £100,000 threshold. This creates a significant hidden tax rate of 60% on income between £100,000 and £125,140. Once an individual's income hits £125,140, their Personal Allowance is completely eliminated, meaning their entire income is subject to tax.

The freeze on this £100,000 withdrawal threshold is equally impactful. As more professionals and managers see their salaries increase, they are being pulled into this 60% marginal tax rate zone, a phenomenon that is a direct result of the government's frozen thresholds strategy.

Fact 3: The Critical Difference for Scottish Taxpayers

For individuals resident in Scotland, the Personal Allowance remains the UK-wide £12,570, but the income tax *rates and bands* are set by the Scottish Parliament. This creates a distinct tax landscape for Scottish taxpayers in 2025/2026, often resulting in higher tax bills than their counterparts in England, Wales, and Northern Ireland.

The Scottish Income Tax system for 2025/2026 includes six bands, compared to the three main bands in the rest of the UK. The key difference is that the Higher Rate of tax (42% in Scotland) begins at a significantly lower income level than the UK-wide threshold of £50,270.

Scottish Income Tax Bands 2025/2026 (Excluding PA):

  • Starter Rate (19%): £12,571 to £15,397 (approx.)
  • Basic Rate (20%): £15,398 to £27,491 (approx.)
  • Intermediate Rate (21%): £27,492 to £43,662 (approx.)
  • Higher Rate (42%): £43,663 to £75,000 (approx.)
  • Advanced Rate (45%): £75,001 to £125,140 (approx.)
  • Top Rate (48%): Above £125,140

This divergence means that a Scottish taxpayer will face the 42% higher rate on income above roughly £43,663, while an English taxpayer only starts paying 40% on income above £50,270. This gap is a crucial consideration for cross-border workers and financial planning in Scotland.

Fact 4: The Marriage Allowance is Locked at £1,260

Another key tax-free allowance that remains frozen for 2025/2026 is the Marriage Allowance. This is a vital mechanism for married couples and civil partners where one partner is a non-taxpayer (earning less than £12,570) and the other is a basic-rate taxpayer.

The Marriage Allowance for 2025/2026 is £1,260.

This allows the non-taxpaying partner to transfer £1,260 of their unused Personal Allowance to their spouse. The benefit to the couple is a tax reduction of 20% of the transferred amount, which equates to a maximum saving of £252 per year.

The eligibility criteria remain strict: the recipient of the transfer must be a basic-rate taxpayer (paying 20% tax). If the recipient is a higher or additional rate taxpayer, the allowance cannot be claimed. Given the frozen thresholds, more people are becoming basic-rate taxpayers, making this allowance potentially more relevant to a growing number of couples.

Fact 5: National Insurance Changes Offer a Partial Offset

While the Income Tax Personal Allowance remains frozen, the overall tax burden for many employees has been partially offset by significant changes to National Insurance Contributions (NICs) for the 2025/2026 tax year. These changes were a major fiscal event designed to boost take-home pay for working individuals.

The main rate of employee Class 1 National Insurance Contributions (NICs) has been cut. For the 2025/2026 tax year, the main employee rate has been set at 8% on earnings between the Primary Threshold and the Upper Earnings Limit. This is a substantial reduction from the previous rates, providing a much-needed boost to net pay for employees.

However, employers have also seen changes. The employer's Class 1 NIC rate has seen an increase, which is a factor for businesses to consider. The crucial point for individuals is that the benefit of the NI cut must be weighed directly against the increased Income Tax liability caused by the frozen Personal Allowance. For many, the NI cut provides immediate relief, but the long-term effect of the PA freeze (fiscal drag) is a continuous increase in the tax burden over several years.

Strategic Financial Planning for the Frozen Allowance

With the Personal Allowance locked at £12,570 until 2028, proactive financial planning is more important than ever. Taxpayers should focus on strategies that utilise other tax-efficient wrappers and allowances:

  • Maximise ISA Contributions: Utilising the annual ISA allowance (£20,000 for 2025/2026) ensures that all savings and investment gains are shielded from Income Tax, Capital Gains Tax, and Dividend Tax.
  • Boost Pension Contributions: Paying into a pension reduces your taxable income, as contributions are typically deducted from gross pay. This is especially effective for those close to the £50,270 higher-rate threshold or the £100,000 taper threshold, as it can help them avoid the higher marginal tax rates.
  • Claim Marriage Allowance: If eligible, ensure the £1,260 transfer is claimed, as this is an easy way to save up to £252 a year that many couples still miss.
  • Consider Salary Sacrifice: Using schemes like cycle-to-work or pension salary sacrifice reduces your taxable income and National Insurance contributions, offering a double benefit in the face of frozen thresholds.

The Personal Allowance freeze for 2025/2026 is a definitive policy that solidifies the government's reliance on fiscal drag. While the £12,570 allowance provides an initial tax-free buffer, the fixed nature of this threshold—and the higher-rate threshold at £50,270—means that as your income grows, your effective tax rate will continue to creep up, making strategic tax planning essential for all UK workers.
