UK Inheritance Tax: How to Protect Your Pensions and Savings

Understanding the New UK Inheritance Tax Rules for Farms and Family Businesses

The landscape for inheriting agricultural and business assets in the UK has shifted significantly. As of April 6, 2026, a new inheritance tax (IHT) regime has come into force, altering how family farms and businesses are taxed upon the death of an owner. While the government adjusted the thresholds following widespread protests, the new rules create a tiered system of relief that may present “significant challenges” for many estates.

The New Tax Thresholds and Reliefs

Under the current regime, the government has implemented a specific allowance for combined agricultural and business property. The core of the new rule is a tiered relief system designed to protect smaller family operations while ensuring larger estates contribute more.

• 100% Relief: The first £2.5 million of combined agricultural and business property continues to receive full relief from inheritance tax.
• 50% Relief: Any value exceeding the £2.5 million threshold receives 50% relief.
• Individual Allowance: This £2.5 million allowance is available to each person.

This framework is a departure from the original proposal announced in October 2024, which intended to set the threshold at £1 million and apply a 20% tax on assets above that mark. Following pressure from MPs and rural campaigners, the government increased the threshold to £2.5 million just before Christmas 2025 to protect more “ordinary family farms.”

Impact on the Farming Community

While the National Farmers’ Union and the Country Land and Business Association have welcomed the increase in the threshold, the changes remain a point of contention. The primary concern is that the valuation of a farm often includes expensive machinery and land, which can easily push a business over the £2.5 million limit even if the operation runs on narrow profit margins.

Accountants, including experts from BDO, have described the implementation of this regime as a “watershed moment” for the community. There are ongoing fears that the tax burden could make it unaffordable for some families to pass their farms to the next generation.

Frequently Asked Questions

How does the new rule differ from the original 2024 proposal?

The original plan was to impose a 20% tax on inherited agricultural assets worth more than £1 million. After significant protests and political pressure, the government “watered down” the plan, raising the 100% relief threshold to £2.5 million.

Who is most affected by these changes?

The changes primarily affect larger estates and family businesses that own significant land and machinery. Even businesses with low liquidity may discover themselves taxable if their asset valuation exceeds the £2.5 million per person threshold.

What is the government’s justification for the change?

Environment Secretary Emma Reynolds stated that the changes are intended to protect ordinary family farms while ensuring that larger estates contribute more to the public purse.
