5 Crucial UK Personal Allowance And Tax Numbers For 2025/2026: Why The Freeze Matters Now

The UK Personal Allowance for the 2025/2026 tax year remains a crucial, yet deeply controversial, figure for millions of taxpayers across the United Kingdom. As of late 2025, the official tax-free allowance is confirmed to be held at its current level, a decision that is having a profound and increasing impact on personal finances, primarily through a phenomenon known as 'fiscal drag.' This article provides a comprehensive, up-to-date breakdown of the five most important tax numbers for the 2025/2026 fiscal year, beginning on 6 April 2025, and explains exactly why the government's continued freeze on the Personal Allowance is shifting the tax burden to historic highs. The continued stability of the core tax rates for 2025/2026—Basic Rate (20%), Higher Rate (40%), and Additional Rate (45%)—combined with the frozen thresholds, means that even modest pay rises will push more individuals into higher tax brackets, effectively increasing the overall tax take for the Exchequer. Understanding these key figures is essential for any UK earner looking to navigate the current tax landscape and plan their financial future effectively.

The 5 Essential UK Tax Numbers for the 2025/2026 Tax Year

The financial year 2025/2026 is defined by a lack of movement in key tax thresholds, a strategy that is proving to be a highly effective, albeit stealthy, method of tax increase. The following five numbers are the bedrock of the UK Income Tax system for this period.

1. The Personal Allowance (PA): £12,570

The most critical number for every UK taxpayer is the Personal Allowance (PA), the amount of income you can earn before you begin paying Income Tax. For the 2025/2026 tax year, the PA is officially £12,570. This figure has been frozen since the 2021/2022 tax year and is now legislated to remain at this level until 5 April 2031. For most taxpayers, this is the entire tax-free allowance they will receive. However, the allowance is reduced, or tapered, for high earners. For every £2 of income earned over £100,000, the Personal Allowance is reduced by £1. This tapering means the Personal Allowance is completely withdrawn once an individual’s income reaches £125,140.

2. The Higher Rate Threshold: £50,270

The Higher Rate Threshold (HRT) is the point at which an individual begins paying the 40% Higher Rate of Income Tax. For the 2025/2026 tax year, this threshold is frozen at £50,270. This figure is calculated by adding the frozen Personal Allowance (£12,570) to the Basic Rate Limit (the amount of income taxed at 20%), which is £37,700. The HRT freeze is the primary mechanism driving the controversial 'fiscal drag' effect, as wage inflation pushes more ordinary workers into the 40% tax bracket. Since the freeze began, there has been a significant increase in the number of higher rate taxpayers.

3. The Additional Rate Threshold (ART): £125,140

The Additional Rate Threshold (ART) is the income level at which the 45% Additional Rate of Income Tax begins to apply. This threshold is also frozen at £125,140 for 2025/2026. This threshold is particularly significant because it is the exact point at which the Personal Allowance is completely lost due to the tapering rule. Any income earned above this level is subject to the highest 45% tax rate. The freeze on this threshold ensures that the tax burden on the UK's highest earners remains high, contributing to the overall increase in the national tax take.

Understanding the Impact of the Extended Freeze: Fiscal Drag

The most important concept to grasp about the 2025/2026 tax year is Fiscal Drag. This term refers to the process where, as wages rise with inflation, more people are pulled into higher tax brackets or start paying tax on a greater proportion of their income, even if their real-terms spending power has not increased. The government's decision to freeze the Personal Allowance at £12,570 and the Higher Rate Threshold at £50,270 until 2031 is a deliberate policy to increase tax revenue without explicitly raising tax rates. The result is that the overall tax burden is being pushed towards historic highs.

The Silent Tax Hike

* Erosion of Allowance: With inflation, the real value of the £12,570 Personal Allowance decreases each year, meaning taxpayers are paying tax on a larger portion of their income in real terms. * More Higher Rate Taxpayers: As average wages increase, taxpayers who were previously paying only the 20% Basic Rate of Income Tax are now crossing the £50,270 threshold and paying 40% on their marginal income. * Dividend Tax Drag: High earners must also consider the impact of frozen thresholds on other forms of income, such as the Dividend Allowance, which contributes to an overall 'tax drag' on investment returns.

Key Related Allowances and Tax Entities for 2025/2026

While the Personal Allowance is the cornerstone, several other allowances and entities are critical for a complete picture of the 2025/2026 tax environment, ensuring high topical authority for this guide.

4. Transferable Tax Allowance (Marriage Allowance): £1,260

The Transferable Tax Allowance, commonly known as the Marriage Allowance, allows a spouse or civil partner who earns less than the Personal Allowance (a non-taxpayer) to transfer £1,260 of their unused allowance to their partner. This transfer can result in a tax saving of up to £252 per year for the recipient (20% of £1,260), provided the recipient is a Basic Rate taxpayer (does not pay the 40% Higher Rate).

5. National Insurance Contributions (NICs) Primary Threshold: £12,570

For the 2025/2026 tax year, the National Insurance Primary Threshold (the point at which employees start paying Class 1 NICs) is aligned with the Personal Allowance at £12,570 per year. This alignment simplifies the tax system, ensuring that an employee does not pay Income Tax or National Insurance until their earnings exceed £12,570. However, employers begin paying contributions at a lower Secondary Threshold (£96 per week).

Other Relevant Tax Entities and Financial Considerations for 2025/2026:

• Blind Person's Allowance: An additional tax-free amount of £3,130 is available to registered blind individuals.
• Starting Rate for Savings: A 0% tax rate applies to savings income up to £5,000, depending on the individual's overall income.
• Employment Allowance: This allowance, which helps small businesses reduce their employers' National Insurance Contributions, is subject to changes and should be reviewed by business owners.
• Capital Gains Tax (CGT): Changes to CGT allowances and rates remain a significant consideration for investors and property owners.
• Advance Tax Clearance Service (ATCS): A new service introduced to provide greater certainty on complex tax matters.
• ISA Limits: The annual ISA allowance remains a vital tool for maximising tax-free savings and mitigating the effects of fiscal drag on investment income.

The 2025/2026 tax year is defined by stability in the numbers but a significant shift in the tax burden. The frozen Personal Allowance of £12,570 is not a benign figure; it is the engine of fiscal drag, a strategy that will continue to pull more UK workers into higher tax bands and increase the overall tax liability across the country.
