King Charles has become the first British monarch in modern times to publicly disclose his tax bill, revealing he paid £12.9 million for the 2024-2025 financial year. This figure places the King among the United Kingdom's top 100 taxpayers. The Prince of Wales, Prince William, also revealed his tax payment for the same period, amounting to £7.76 million.

These disclosures come amidst growing calls for greater transparency in royal finances, particularly in the wake of past scandals. The decision to publish these personal tax figures was a voluntary one, made by both the King and Prince William, according to their respective offices. Buckingham Palace stated the move aims to increase transparency and foster a better understanding of the accountability surrounding the monarchy.

The annual royal report and accounts also detailed the Sovereign Grant, the primary source of public funding for the Royal Household. This grant, which covers running costs such as staffing, travel for official engagements, and palace maintenance, is projected to nearly double within three years, reaching just under £100 million by 2027-28. For 2024-25, the Sovereign Grant was £86.3 million, with £51.8 million allocated for core expenses and an additional £34.5 million earmarked for Buckingham Palace renovations.

Once the extensive renovations at Buckingham Palace are completed, the total Sovereign Grant figure is expected to decrease from the current £137.9 million to £99.9 million. However, this revised amount will still represent a significant increase compared to previous years before the renovation funding was factored in.

Further details from the accounts show that the King paid £11.7 million in tax for the 2023-24 financial year, while Prince William paid £8.34 million for the same period. Since Charles ascended to the throne in 2022 and William became the Prince of Wales, their combined tax payments to HM Revenue and Customs have exceeded £50 million.

While the published figures highlight the substantial tax paid by the King, they do not offer a breakdown of how the tax liability was calculated. Experts have noted that this lack of detail makes the disclosure somewhat opaque. Questions remain regarding the specific types of tax paid, such as income tax and capital gains tax, and the expenses deducted to arrive at the taxable income.

In related news, the report confirmed that King Charles and Queen Camilla will continue to reside at Clarence House following the completion of the Buckingham Palace renovations, rather than relocating to the palace itself. The King's income, partly derived from the Duchy of Lancaster, provides funds for his official and private expenditures.

The shift towards greater financial openness by the King and Prince of Wales appears to be a direct response to public sentiment and concerns raised by Members of Parliament regarding accountability in the use of public funds. This voluntary disclosure sets a new precedent for royal financial transparency.
