Buckingham Palace has disclosed that the king has paid tax of £11.7 million in 2023-24 and £12.9 million in 2024-25. The bulk of this tax liability arises from his income from the Duchy of Lancaster, which for 2023-24 was £27.5 million.
This makes him one of the top 100 taxpayers in the country. Kensington Palace has also disclosed that Prince William paid £7.76 million in tax on the profits of the Duchy of Cornwall.
