One of the greatest honours in life is being an heir, as it symbolises a sense of purpose, especially if one is to inherit a family legacy. For others, it may bring emotional fulfilment. However, future heirs may be impacted in a few months, after HM Revenue & Customs (HMRC) announced Inheritance Tax rules changes in 2026. Discover what these changes entail for heirs in 2026 and beyond, and how they may potentially affect you, your family and your prospective heirs’ inheritance.
The role of Inheritance Tax in the UK
Inheritance itself plays a significant role in keeping legacies alive and ensures the financial security for future generations. However, it also plays a key role in the UK, particularly in taxation. Paying taxes on one’s inheritance may seem unfair to some, but according to a report by MP Estate Planning, it has great social and economic ramifications.
The ramifications of the UK’s Inheritance Tax
- Inheritance Tax revenue, along with other taxes, funds essential public services
- Decreases wealth inequality by contributing a high share to public funding
- Manages and lowers the UK’s national debt
- Influences certain behaviours, such as philanthropy, thanks to tax relief for charitable donations
While it may play a vital role in a social and economic sense, most people try to find ways to avoid paying higher taxes through certain exemptions. Keeping up with all the rules and regulations of Inheritance Tax is no easy feat, and heirs may be worse for wear in 2026, as the Inheritance Tax rules are set to change in a few months, with some exemptions falling away.
Inheritance Tax rules to change in 2026
The majority of people have been concerned about the upcoming Autumn Budget and its potential reforms set to be introduced in 2026. One of the reforms that has people buzzing is the change to the HMRC’s most popular Inheritance Tax exemption. Now, new fears have settled as an entirely different group of heirs will have to face new rules in 2026.
According to Oldfield Accountancy & Advisory, those who will be impacted by the changes the most are:
- Family farms worth more than £1 million
- Family trusts consisting of company shares or land
- Family businesses and partnerships
- People with significant investments and pension savings
- Limited companies
Understanding how these Inheritance Tax changes will impact heirs in a few months may help some in making vital business decisions now.
The impact on future heirs in a few months
New Inheritance Tax rules for long-term residents were introduced on 6 April 2025, as per an official statement from the HMRC on the Inheritance Tax. Now, one year later, from April 2026, heirs will once again have to adapt to the following changes:
- Business and Agriculture Property Reliefs
- These assets qualify for 100% relief at a £1 million allowance
- Assets above the allowance will face a lower relief rate of 50% and a 20% tax rate on the excess
- Unused allowance is non-transferable to the surviving spouse
- Pensions
- Inheritance Tax may be payable on pensions after death
- New tax rules to be integrated from April 2027
- Trusts
- Trusts settled before 29 October 2024 will be tax-free at a £1 million allowance each
- Trusts settled on or after 30 October 2024 will split the £1 million allowance
Financial experts believe that it would be best for most to act before the upcoming Autumn Budget and Inheritance Tax changes. Specific advice for pensioners is to spend their pension savings quickly or face an 87% tax penalty. Others may want to review their succession plans, assess their trust structures, make use of the lifetime gifting exemption, and review their wills to ensure that they fully benefit from the APR/BPR allowances. Whatever your strategy plan may be, ensure that it is timely.
