What Changed on 6 April 2026?
For generations, UK farming families relied on Agricultural Property Relief (APR) and Business Property Relief (BPR) to pass land and assets to the next generation free of Inheritance Tax. Under the rules that applied until 5 April 2026, qualifying agricultural land could attract 100% relief — meaning the entire estate passed on without an IHT bill.
From 6 April 2026, HMRC now caps the combined APR and BPR relief at £2.5 million per individual (or £5 million for a couple using transferable allowances). Anything above that threshold is taxed at the standard IHT rate of 40%, unless you can utilise the nil-rate band (£325,000) and the residence nil-rate band (£175,000).

The critical challenge for farming families is that most of an estate’s value is tied up in land and buildings — assets that are very difficult to liquidate. Selling even a portion of a farm to pay an IHT bill can destroy the viability of the operation for the next generation. A whole-of-life or term life insurance policy written in trust can pay the IHT bill directly, without any need to sell a single acre.
