Prince William decides not to disclose tax bill unlike King Charles

The Prince chooses not to reveal his tax bill, differing from his father who voluntarily disclosed his payment.

Prince William has opted not to disclose his tax bill, a departure from the transparency demonstrated by his father, King Charles. 

As the heir to the throne, William benefits from the surplus profits of the Duchy of Cornwall estate, which spans 23 counties in England and Wales. These funds support the official, charitable, and private lives of William, Princess Kate, and their children: Prince George, 11, Princess Charlotte, 9, and Prince Louis, 6.

Kensington Palace revealed that William paid tax at the standard UK rate after deducting official costs, although there is no requirement for him to disclose his tax bill. In contrast, King Charles voluntarily revealed he paid £5.9 million in income tax. The King's annual review includes detailed accounts of his income, expenditures, and staff, but no such details were provided for William and Kate's household.

The Duchy of Cornwall claims a Crown exemption, meaning William is not legally required to pay income or corporation tax on its revenues, although he has chosen to pay income tax voluntarily. This practice began with King Charles in 1993. Last year, William received £6 million from the Duchy due to his mid-year assumption of the Duke of Cornwall title.
