Finance Act 2026 Granted Royal Assent: Key Tax Changes Explained

The Finance Act 2026 is the latest UK tax law to come out of the government’s annual budget process. It received Royal Assent on 18 March 2026, which means it has now passed through Parliament and become law. In practical terms, it gives legal effect to a range of tax measures announced in Budget 2025 and set out in the Finance Bill 2025-26.

For businesses, investors, advisers, landlords, and high-net-worth individuals, this matters because the Finance Act is where tax announcements stop being proposals and start becoming enforceable legislation. Some measures take effect from Royal Assent, while others start on later dates such as 6 April 2026 or 6 April 2027.

What is the new UK Finance Act 2026?

The Finance Act is the main annual tax law passed by Parliament. Each year, the chancellor announces tax measures in the budget. The government then introduces a finance bill to put those measures into legislation. Once Parliament approves the bill and it receives Royal Assent, it becomes the Finance Act for that year.

So, the Finance Act 2026 is the law that followed Budget 2025. It is not just one tax change. It is a package of tax rules, rate changes, relief reforms, compliance rules, and administrative measures.

What is the purpose of the Finance Act?

The purpose of the Finance Act is simple. It gives legal force to the government’s tax decisions. Without it, many budget announcements would remain proposals only. The House of Commons Library notes that the annual Finance Bill is used to implement the tax measures set out in the Chancellor’s statement, and at least one Finance Bill is needed each year because taxes such as income tax and corporation tax must be renewed by legislation annually.

In short, the Finance Act does three main jobs:

• Sets or renews annual tax charges
• Changes tax rates, reliefs, and allowances
• Updates HMRC powers, compliance rules, and tax administration

What is included in the Finance Act 2026?

The Finance Act 2026 is broad, but some of the most significant measures include the following.

1. Changes to dividend and savings income taxation

Budget 2025 confirmed that legislation would be introduced in Finance Bill 2025-26 to increase dividend income tax rates from 6 April 2026. It also set out later changes to savings income rates from 6 April 2027.

2. Reform of carried interest taxation

The government said Finance Bill 2025-26 would move carried interest into an Income Tax framework from April 2026. That is an important shift for affected fund managers and investment structures.

3. Agricultural Property Relief and Business Property Relief changes

One of the most discussed parts of the Act is the reform of Agricultural Property Relief (APR) and Business Property Relief (BPR). HMRC’s policy papers state that, from 6 April 2026, a new £1 million allowance applies to the combined value of qualifying property attracting 100% relief, with 50% relief applying above that allowance in the cases covered by the reform.

4. Mandatory registration of tax advisers

Finance Act 2026 also supports a new regime requiring tax advisers who deal with HMRC on behalf of clients to register and meet minimum standards. HMRC says this will begin in May 2026, with a transitional period of at least three months.

5. EIS and VCT changes

Budget 2025 also said Finance Bill 2025-26 would increase the investment and gross asset limits in the Enterprise Investment Scheme (EIS) and Venture Capital Trust (VCT) rules, while reducing VCT income tax relief from 30% to 20%, with changes taking effect from 6 April 2026.

6. Inheritance Tax changes affecting pensions

HMRC has also published material showing that legislation in the Finance Bill 2025-26 would bring most unused pension funds and pension death benefits into scope for inheritance tax from 6 April 2027. That gives individuals and families time to review estate planning before the rules bite.

Why Finance Act 2026 matters

This Act matters because it affects both current planning and future planning.

For some taxpayers, the immediate issue is compliance. For others, it is timing. A measure may now be law, but its effective date may still be months away. That distinction is vital when making decisions on share structures, succession planning, investment, remuneration, or tax advice arrangements.

It also matters because Finance Acts often shape behaviour before the start date arrives. For example:

• families may revisit succession and estate plans
• tax advisers may prepare for registration rules
• investors may review EIS or VCT timing
• businesses may reassess dividend extraction strategies
• affected individuals may review pension and carried interest planning

Conclusion

The Finance Act 2026 in UK is now law. It received Royal Assent on 18 March 2026, and it brings a wide range of Budget 2025 tax measures into the statute book. Some changes apply now. Others start from 6 April 2026 or 6 April 2027. Either way, this is the point where proposals become rules.

For anyone affected, the key step is not just knowing that the Act exists. It is knowing which part applies to you, when it starts, and what action should be taken before the deadline arrives.
