5 Quiet UK Tax Changes For 2026 That Will Hit Your Wallet Harder
The 2026/2027 UK tax year is shaping up to be a period of significant, yet often under-reported, fiscal adjustment. While the headlines often focus on immediate giveaways, a series of quieter legislative changes and the continuation of existing policies are set to profoundly impact personal finances, business owners, and inheritors across the country. These shifts, which take effect from April 2026, represent a strategic effort by the government to boost the Exchequer through what is commonly known as "fiscal drag" and targeted reforms on specific asset classes and reliefs.
As of December 2025, the key focus for taxpayers preparing for 2026 must be the compounding effect of frozen allowances, alongside major structural changes to Inheritance Tax (IHT) and the taxation of investment income. Understanding these specific, confirmed changes—from the cap on Business Property Relief to new dividend tax rates—is essential for proactive financial planning and mitigating the coming tax burden.
The Extended Freeze: The Silent Income Tax Hike of 2026
One of the most impactful, yet least talked about, changes affecting millions of UK workers is the extended freeze on Income Tax thresholds. This policy is the engine of "fiscal drag," quietly pulling taxpayers into higher brackets.
The Prolonged Income Tax and NICs Threshold Freeze
The Personal Allowance and the Higher Rate Threshold (HRT) were initially frozen until April 2026. However, this freeze has since been extended, meaning these key thresholds will now remain static until April 2028.
- Personal Allowance: The amount you can earn tax-free remains fixed.
- Higher Rate Threshold (HRT): The point at which the 40% tax rate kicks in remains fixed.
By keeping the thresholds fixed while wages and inflation rise, a greater proportion of an individual's income becomes taxable, and more people are pushed into the 40% higher rate band. This is, effectively, a stealth tax rise for approximately 37 million taxpayers.
The Impact of Fiscal Drag on the Average Worker
The power of the freeze is in its cumulative effect. For someone receiving a standard annual pay rise, a larger chunk of that raise is taxed at their marginal rate, or worse, pushes them into a new, higher tax bracket. This is why the freeze is often cited as one of the most significant "quiet tax rises" hitting the UK by 2026.
Major Overhaul of Inheritance Tax (IHT) Reliefs from April 2026
The Inheritance Tax system is set for a structural shake-up in the 2026/2027 tax year, specifically targeting two crucial reliefs used by business owners and farming families: Business Property Relief (BPR) and Agricultural Property Relief (APR).
The £1 Million Cap on Business and Agricultural Relief
From April 6, 2026, the government is introducing a significant restriction on the amount of assets eligible for 100% IHT relief under BPR and APR.
The key change is the introduction of a £1 million cap on the value of assets that can qualify for these reliefs. For any value above this £1 million threshold, the asset will no longer be eligible for the 100% relief.
This measure is aimed at limiting the scope of IHT planning, particularly for large family businesses and farms. Business owners, family farms, and anyone with significant business or agricultural property must review their estate planning immediately to account for this new liability.
Targeted Increases: Dividends, Savings, and Carried Interest
The 2026 tax year also introduces higher rates for specific types of investment income, alongside a major reform for the financial sector.
1. Dividend and Savings Income Tax Rises
Confirmed changes for the 2026/2027 tax year include increases to the rates of income tax on savings and dividend income, which will affect investors and company directors who take income via dividends.
- Dividend Income: The dividend ordinary rate is set to increase to 10.75%, and the dividend upper rate will rise to 35.75% from April 6, 2026.
- Savings Income: The savings basic rate will increase to 22% from April 6, 2026.
These increases mean that non-ISA investment returns will be subject to a higher tax burden, making tax-efficient wrappers like ISAs and pensions even more valuable for long-term planning.
2. The Carried Interest Crackdown
In a move specifically targeting the private equity and financial services sector, the government announced plans to reform the tax treatment of 'carried interest'—the share of profits received by investment managers.
From April 2026, carried interest is planned to be brought within the Income Tax regime. This means it will be taxed as income, rather than capital, a significant shift that will result in a much higher tax bill for fund managers and partners who rely on this type of remuneration.
Business Taxation: Corporation Tax and Capital Allowances in 2026
For UK businesses, the focus for 2026 is less on rate changes and more on adjustments to capital allowances, which impact investment decisions.
Stable Corporation Tax Rates
As of the most recent announcements, the main rate of Corporation Tax (CT) is scheduled to remain at 25% for the financial year beginning April 1, 2026. The small profits rate is also set to remain at 19%.
The Reduction in Writing-Down Allowances
A key change for businesses that invest in plant and machinery relates to capital allowances. From April 1, 2026 (for Corporation Tax) and April 6, 2026 (for Income Tax), the main rate writing-down allowances (WDAs) will be reduced.
The main rate WDA is set to drop from 18% to 14%. This reduction means that businesses will recover the cost of their assets more slowly, increasing their taxable profits in the short term. This change, alongside the stability of the CT rate, signals a continued policy of encouraging investment but through a slower depreciation schedule.
Key Entities and Tax Concepts for 2026 Planning
The following entities and concepts are central to understanding the 2026 tax landscape and should be the focus of any forward-looking financial review:
- Fiscal Drag: The primary mechanism driving higher income tax revenue due to the extended freeze on thresholds (Personal Allowance, HRT) until 2028.
- Business Property Relief (BPR): Subject to the new £1 million cap from April 2026, fundamentally altering IHT planning for business owners.
- Agricultural Property Relief (APR): Also impacted by the £1 million cap, causing concern for farming communities.
- Carried Interest: Moving from a capital gains tax treatment to a higher income tax regime.
- Dividend Tax Rates: Specific increases to the ordinary (10.75%) and upper (35.75%) rates from April 2026.
- Writing-Down Allowances (WDAs): The reduction from 18% to 14% for main-rate assets, impacting business investment decisions.
- Corporation Tax (CT): Remaining stable at 25% for the main rate.
- HMRC Letter Update: A major system change affecting how 37 million taxpayers receive official correspondence.
- Savings Income: The basic rate increasing to 22%.
- Capital Gains Tax (CGT): While rates are stable, allowances have been reduced in prior years, compounding the effect of rising investment taxes.
- Income Tax Thresholds: Frozen until April 2028.
- National Insurance Contributions (NICs): Thresholds also frozen alongside income tax.
- Alternative Finance Tax Rules: Changes affecting capital gains tax, corporation tax, income tax, and Annual Tax on Enveloped Dwellings (ATED).
The 2026 tax year is not defined by a single, dramatic tax hike, but rather by a series of targeted and structural adjustments. The continued freezing of personal tax thresholds, the cap on IHT reliefs, and the increases in dividend and savings tax rates ensure that both personal and business wealth will be subject to a higher effective tax rate. Proactive engagement with a financial adviser is crucial before April 2026 to restructure investments, review estate plans, and mitigate the impact of these quietly implemented changes.
