IHT Agricultural and Business Property Relief changes confirmed

Despite intense lobbying by the farming community, the proposed reduction in IHT Business and Agricultural Property reliefs are included in the draft Finance Bill 2025-26.

On 21 July 2025, the government published draft legislation for Finance Bill 2025-26. The consultation period for the draft legislation is open until 15 September 2025. This comes at a time when the government has seen borrowing in June surge to the second highest level on record and placing further pressure on public finances and increasing the urgency for tax reforms.

The legislation includes confirmation of a significant overhaul of Inheritance Tax (IHT) reliefs that were first announced in the Autumn Budget 2024. These measures faced criticism over their potential impact on small farms and rural communities. However, with the publication of the Finance Bill, these measures now look set to come into effect from 6 April 2026.

The changes will see the introduction of a new £1 million allowance that will apply to the combined value of property in an estate qualifying for 100% business property relief or 100% agricultural property relief. This means that the existing 100% rate of IHT relief will only apply to the combined value of property in an estate qualifying for 100% business property relief or 100% agricultural property relief. The rate of IHT relief will be reduced to 50% for the value of any qualifying assets over £1 million. This means that any assets receiving 50% relief will be effectively taxed at 20% IHT (the full rate being 40%).

This change applies per individual, meaning married couples could potentially pass on up to £3 million tax-free between them (when combined with nil-rate bands).

The government has also confirmed they will reduce the rate of business property relief available from 100% to 50% in all circumstances for shares designated as “not listed” on the markets of recognised stock exchanges, such as AIM. The existing rate of relief will continue at 50% where it is currently this rate and will also not be affected by the new allowance.

It was also announced that the option to pay IHT by equal annual instalments over 10 years interest-free will be extended to all qualifying property which is eligible for agricultural property relief or business property relief.
