5 Major UK Tax Changes Hitting Your Finances In 2026: The Shocking £1M Cap And Frozen Allowances

Contents
The UK tax landscape is set for a significant overhaul in the 2026/2027 tax year, with several major policy shifts confirmed to take effect from April 2026. These changes, which range from a seismic cap on Inheritance Tax (IHT) reliefs to a rise in Dividend Tax rates and the continuation of frozen Personal Allowances, are set to impact a wide spectrum of taxpayers, from high-net-worth individuals and business owners to basic-rate taxpayers and investors. Understanding the implications of these confirmed changes now, in late 2025, is essential for effective fiscal planning, as the combined effect of these policies will significantly alter personal and business tax bills. The long-term strategy of the government's fiscal policy is becoming clearer, moving beyond immediate National Insurance and Income Tax adjustments to target specific reliefs and investment income. The most critical change for many wealth holders is the introduction of a £1 million limit on key IHT reliefs, a move that financial advisors are already flagging as the biggest shake-up to estate planning in decades. This detailed guide breaks down the five most crucial tax changes you must prepare for ahead of the 2026 deadline.

The Five Confirmed UK Tax Policy Earthquakes Starting April 2026

The government has legislated or announced firm plans for several major tax reforms that will converge in the 2026/2027 tax year. While the political climate remains dynamic, these specific changes offer a clear roadmap for future tax liabilities, demanding immediate attention from taxpayers and tax planning professionals.

1. The Seismic £1 Million Cap on Inheritance Tax Reliefs (APR & BPR)

One of the most significant and potentially costly changes for business owners and farming families is the reform of two powerful Inheritance Tax (IHT) reliefs: Agricultural Property Relief (APR) and Business Property Relief (BPR). * The New Cap: From 6 April 2026, the combined value of assets eligible for 100% APR and BPR will be capped at £1 million. * The Impact: Currently, qualifying assets can be passed on free of IHT, regardless of their value. The new £1 million cap means that any value above this limit will be subject to the standard 40% Inheritance Tax rate, unless other exemptions apply. * Who is Affected? This change primarily targets owners of large farms, estates, and substantial trading businesses. It fundamentally alters the strategy for long-term estate planning and wealth transfer, necessitating an urgent review of wills, trusts, and business structures. * A Small Concession: Separately, from April 2026, the option to pay IHT in equal annual instalments over 10 years, interest-free, will be extended to *all* property, not just land and buildings, which may offer minor cash flow relief.

2. The Hidden Tax Hike: Personal Allowance Freeze Extended to 2028

While not a direct *increase* in tax rates, the continued freezing of Personal Tax thresholds is arguably the biggest hidden tax rise for the majority of UK workers. * The Freeze: The standard Personal Allowance—the amount of income you can earn before paying Income Tax—remains frozen at £12,570. Crucially, this freeze has been extended until April 2028, instead of the previously scheduled end date of April 2026. * Fiscal Drag: As wages increase due to inflation and general economic growth, more of a person's earnings are pulled into the tax net, a phenomenon known as "fiscal drag." This effectively means that even with a pay rise, the real-terms value of your take-home pay decreases as a larger proportion is taxed. * Impact on Taxpayers: This affects all UK taxpayers, especially basic-rate and higher-rate taxpayers, as the starting points for the 40% and 45% tax bands are also frozen, pushing more people into higher tax brackets.

3. Dividend Tax Rates Set to Rise by 2%

Investors and company directors who take income via dividends must prepare for a significant increase in their tax liability from April 2026. * The Increase: The government has confirmed that Dividend Tax rates will rise by 2% for both basic-rate and higher-rate taxpayers. * New Rates (Expected): * Basic-rate taxpayers: Current rate + 2% * Higher-rate taxpayers: Current rate + 2% * Additional-rate taxpayers: Current rate + 2% * Allowance Remains Low: The separate Dividend Allowance, which is the amount of dividend income you can receive tax-free, is expected to remain at the low figure of £500. * Strategic Shift: This change makes taking profits via dividends less tax-efficient and increases the tax burden on small business owners and investors who rely on this form of income. It is a clear signal of the government's focus on increasing the tax take from investment and capital income.

4. Carried Interest to be Taxed as Income

A major policy shift impacting the private equity and investment fund sectors is the change to how Carried Interest is taxed. * The Reform: From April 2026, the government plans to bring Carried Interest—the share of a fund's profits paid to its managers—within the Income Tax regime. * Current vs. Future: Historically, Carried Interest has often been treated as a Capital Gain, attracting the lower Capital Gains Tax (CGT) rate (currently 24% for residential property, and 20% for most other assets). Under the new rules, this will be taxed as income, potentially at the 40% or 45% Income Tax rates. * Impact: This is a significant blow to partners and managers in private equity and venture capital firms, dramatically increasing their personal tax bills and potentially influencing the structure and location of future investment funds. This move is part of a broader fiscal policy aimed at ensuring "those with the broadest shoulders pay a bit more."

5. The Non-Dom Tax Regime is Abolished and Replaced

While the abolition of the non-domicile (non-dom) tax regime began earlier, the transition extends into the 2026/2027 tax year, with the new system fully taking effect. * Abolition and Replacement: The long-standing non-dom tax rules are being abolished and replaced with a new system based on UK residency. * The New System: From the 2026/2027 tax year, individuals who have been tax-resident in the UK for more than four years will no longer be able to claim the remittance basis of taxation. Their worldwide income and gains will be subject to UK tax, similar to other UK residents. * Transition: The changes include transitional reliefs for existing non-doms, such as a temporary 50% reduction in the tax on foreign income for the first year of the new regime (2025/2026) and a two-year window to remit previously un-taxed foreign income and gains at a lower 12% rate. This is a complex area that requires specialist advice for high-net-worth individuals relocating to or from the UK.

Crucial Tax Planning Entities and LSI for the 2026 Deadline

The convergence of these policy changes creates a critical window for tax planning and adjustments. Business owners and landlords are particularly exposed to the combined effects of the IHT cap and the frozen tax thresholds. * Inheritance Tax Planning: For those with substantial assets, especially those qualifying for BPR and APR, a review of their estate is paramount. Strategies may involve gifting, restructuring business assets, or exploring the use of trusts before the £1 million cap comes into force. The new rules on trusts and trust reliefs are also a key area of focus for wealth transfer. * Investment Strategy: The rising Dividend Tax rates and the low dividend allowance make the use of tax-efficient wrappers like ISAs (Individual Savings Accounts) more important than ever to shield investment growth from the Exchequer. The discussion around ISA reform and the potential for a UK ISA to encourage investment in UK companies is a related area to watch closely. * HMRC and Digitalisation: While not a direct tax rate change, the ongoing rollout of Making Tax Digital (MTD) for Income Tax Self Assessment (ITSA) means that Self Assessment filers need to be prepared for the final paper filing under the old system for the 2025–26 tax year by 31 January 2027. This digital transformation is a continuous, long-term change affecting how taxpayers interact with HMRC.

The Long-Term Fiscal Outlook Beyond 2026

The overall fiscal policy direction is clear: the tax take is forecast to reach a peacetime record high of 38.2% of GDP by the end of the decade. While the government has implemented cuts to National Insurance in the short term, the long-term strategy relies on the unannounced but highly effective revenue generation from fiscal drag (frozen thresholds) and the closing of specific, expensive tax reliefs (IHT reforms, Carried Interest). The political landscape, including the next General Election, could introduce further changes, but the current, confirmed legislation provides a solid basis for tax planning for the Tax Year 2026/2027. Taxpayers must act proactively to mitigate the impact of these significant reforms, particularly the £1 million cap on IHT reliefs, which represents a fundamental shift in how generational wealth is treated in the UK. Consulting a specialist advisor now is the best way to navigate this complex and costly set of new rules.
