From HM Revenue & Customs · Inheritance Tax Manual
The rate of relief for property is
100% which is unlimited for transfers effected on or after 6 April 1996 until 5 April 2026, or where the charge to tax arises on an earlier transfer by reason of an event occurring on or after that date.
From 6 April 2026,
the 100% rate only applies up to the available amount of the transferor’s 100% allowance, and any value of a chargeable transfer exceeding the available allowance will only be relieved at 50% ().If the shares are traded on a UK recognised stock exchange (and the market is not ‘listed’ for HMRC purposes) or are traded on a stock exchange outside the United Kingdom which is not a recognised stock exchange, the rate is 50% (). These shares now fall under the new categories of and (ac) respectively.
These revised rates will also apply to transfers made on or after 30 October 2024 if the transferor dies on or after 6 April 2026 and within 7 years of the transfer, except for shares traded on a stock exchange outside the United Kingdom which is not a recognised stock exchange.
