King Charles III will publish the amount of personal tax he pays at Buckingham Palace’s sovereign grant briefing as part of a push for greater transparency after controversies involving his younger brother. The disclosure covers taxes on private income from Balmoral and Sandringham and excludes the sovereign grant used for official duties. Prince William is expected to provide similar figures separately. The move is presented as an effort to increase accountability and public confidence in the monarchy.

King Charles III is set to become the first reigning British monarch to disclose the total of his personal tax payments, the palace said, in a step aimed at increasing transparency around royal finances after months of damaging headlines linked to his younger brother, the former Prince Andrew.
What’s Being Released
The figures will be unveiled at Buckingham Palace’s annual briefing on the sovereign grant, the public funding mechanism that supports the official duties of the monarchy. Last year the palace also published a detailed 159-page report explaining how it spent the 86.3 million pounds ($113.7 million) received from the Treasury, including funds for a major palace refurbishment.
Scope Of The Disclosure
The disclosure will cover taxes paid on the king’s private income only — most of which derives from his privately held Balmoral and Sandringham estates, plus interest, savings and investments. The sovereign grant and other funds used to cover official duties are not taxed and will not be included.
Why Now
Palace sources told the BBC that Charles chose to publish his tax payments to “encourage wider understanding and accountability.” The move follows intensified calls from lawmakers and the public for clearer oversight of the royal household after revelations about the conduct of the former Prince Andrew, who was stripped of his titles in 2025 and is under investigation in relation to allegations tied to his association with the convicted sex offender Jeffrey Epstein.
Financial Context
Charles’s private wealth is estimated at about 680 million pounds ($896 million), placing him among the country’s wealthier individuals. Balmoral spans more than 50,000 acres (20,000 hectares) and includes Balmoral Castle; Sandringham covers roughly 20,000 acres (8,000 hectares). Both estates generate private revenue through tourism, farming and other activities.
Prince William, now the Prince of Wales, is expected to release similar details at a separate briefing. His primary private income comes from the Duchy of Cornwall, a trust portfolio of land and investments that reported a profit of 22.9 million pounds ($30.2 million) last year and covers about 130,000 acres (52,000 hectares).
Implications
While the monarch is not legally required to pay income tax, Charles voluntarily pays tax on his private earnings — a practice adopted by Queen Elizabeth II in 1993 and later formalized in a memorandum of understanding between the government and the Crown that also preserves the monarch’s rights to taxpayer privacy. The palace frames the disclosure as part of efforts to bolster public trust and modernize the institution amid ongoing scrutiny.
