The UK tax landscape underwent significant changes from 6 April 2026, marking the beginning of the 2026/27 tax year. These updates, impacting various aspects of personal and business finance, include increased dividend tax rates, a new cap on Inheritance Tax relief for certain assets, the phased introduction of Making Tax Digital for Income Tax, and the removal of the working-from-home tax allowance. Understanding these adjustments is crucial for individuals, investors, landlords, and businesses navigating the evolving fiscal environment.

Dividend Tax Rates See a Significant Rise

Investors and business owners who take income via dividends will notice a considerable shift in their tax liabilities. From 6 April 2026, dividend tax rates have increased by a flat 2 percentage points across all bands. This means the basic rate, previously 8.75%, now stands at 10.75%. The higher rate has climbed from 33.75% to 35.75%, while the additional rate has risen from 39.35% to 41.35%.

This adjustment is expected to be a substantial revenue generator for the Exchequer. HM Treasury projections indicate that the dividend tax increase will raise an estimated £280 million in the 2026/27 tax year alone. This figure is then expected to grow significantly, reaching £1.39 billion by the 2030/31 tax year. These changes underscore a broader trend towards ensuring that dividend income contributes more to the national purse.

Inheritance Tax Reliefs Capped for Agricultural and Business Property

For those with significant agricultural or business assets, the rules around Inheritance Tax (IHT) relief have been tightened. Effective from 6 April 2026, the 100% relief previously available for Agricultural Property Relief (APR) and Business Property Relief (BPR) is now capped. This 100% relief applies only up to a combined allowance of £2.5 million per individual.

Should the value of qualifying APR and BPR assets exceed this £2.5 million threshold, the relief applied to the excess amount will be reduced. Specifically, assets valued above the £2.5 million allowance will now receive 50% relief instead of the full 100%. This represents a notable change for owners of large farms or substantial businesses, who previously might have expected their entire qualifying property to be fully exempt from IHT.

However, there is a provision for couples. The £2.5 million allowance is transferable between spouses and civil partners. This means that a couple can effectively benefit from 100% relief on up to £5 million worth of qualifying agricultural and business property, providing a degree of flexibility and planning opportunity for joint asset holders.

Making Tax Digital for Income Tax Begins Its First Phase

A significant modernisation initiative, Making Tax Digital for Income Tax (MTD for IT), has officially entered its first phase from 6 April 2026. This marks a pivotal shift in how self-employed individuals and landlords manage and report their income to HMRC.

The initial phase of MTD for IT targets sole traders and landlords whose business receipts exceed £50,000. These individuals are now required to maintain digital records of their income and expenditure. Crucially, they must also submit quarterly updates to HMRC using MTD-compatible software. This move aims to streamline tax reporting, reduce errors, and provide HMRC with more real-time data, but it also necessitates a significant administrative adjustment for those falling within its scope.

Other Notable Changes Taking Effect from April 2026

Beyond these headline changes, several other tax adjustments have come into force from April 2026, impacting various segments of the population and economy:

  • State Pension Increase: The UK state pension has seen a rise of 4.8% from April 2026. This increase was confirmed by Chancellor Rachel Reeves in the preceding Budget, providing a boost to pensioners’ income.
  • Working-from-Home Tax Allowance Removed: A widely used benefit during the pandemic era, the working-from-home tax allowance, has been withdrawn. From April 2026, the £6-per-week employee deduction for costs claimed without receipts is no longer available.
  • Plant and Machinery Writing-Down Allowance Cut: Businesses investing in assets will also feel an impact. The main rate of writing-down allowance on plant and machinery has been cut from 18% to 14% from April 2026. This adjustment will affect the rate at which businesses can claim tax relief on their capital expenditures.
"The 2026/27 tax year brings a comprehensive set of fiscal adjustments affecting individuals, investors, landlords, and businesses alike. From higher dividend taxes and capped Inheritance Tax reliefs to the introduction of Making Tax Digital, these changes necessitate careful review and adaptation to ensure compliance and optimise financial planning."

The array of UK tax changes effective from April 2026 underscores a dynamic shift in government revenue generation and tax administration. From increased contributions from dividend income and revised Inheritance Tax reliefs to the march towards digital tax reporting and adjustments to various allowances, stakeholders across the board will need to review their financial strategies. Staying informed and proactive in adapting to these new rules will be key to navigating the evolving tax landscape successfully.
