How a Special Rule Shaped the Distribution of Queen Elizabeth's Estate

King Charles's siblings, Princess Anne, Prince Edward, and Prince Andrew, likely did not inherit any of Queen Elizabeth’s substantial fortune to avoid inheritance tax. A specific rule dictates that only assets transferred from one monarch to their successor are exempt from taxation. This means that any inheritance received by the King's siblings would have been subject to the standard inheritance tax.

The Royal Family benefits from an exemption to standard inheritance tax rules, established in 1993 by Sir John Major's Government. This agreement stipulated that "transfers of assets from one sovereign to his or her successor" are exempt from the 40% tax applied to assets exceeding £325,000. The agreement also covers inheritance from the consort of a former sovereign to a sovereign. The primary goal of this agreement was to "prevent the dilution of the Crown's wealth and ensure the continuity of the monarchy's functioning."

The guidance emphasizes that the monarchy requires sufficient private resources to fulfill its traditional role. While the Crown Estate manages property worth billions, only a portion of its revenue is allocated to the monarch as the Sovereign Grant, with the remainder going to the Treasury. King Charles oversees the Sovereign Grant, which funds the official duties of the Royal Family.

The government's guidance clarifies that anyone inheriting private assets from a sovereign, other than the direct successor, would be subject to inheritance tax. The rule states that inheritance tax is not applied to gifts or bequests from one sovereign to the next, but it is applicable to gifts and bequests to anyone else.
