Royal Transparency Milestone

On 20 June 2026, King Charles III announced that he paid £12.9 million in tax for the 2024‑25 financial year. The figure covers income tax on profits from the Duchy of Lancaster, returns from private investments, and earnings from residential estates such as Sandringham and Balmoral. By publishing this amount, the King became the first modern monarch to reveal his personal tax bill.

The decision follows a series of calls for openness after the Andrew Mountbatten‑Windsor scandals, which highlighted concerns about royal finances. Palace officials framed the disclosure as a personal choice intended to “encourage wider understanding of our accountability.” The move aligns with the sovereign’s ongoing practice of voluntarily paying income tax and capital gains tax, even though the law does not require a monarch to do so.

King Charles’s tax payment reflects an increase from the previous year’s £11.7 million. Combined with Prince William’s £8.34 million contribution, the father‑son duo has paid more than £50 million to HM Revenue & Customs since the accession in 2022. The public release of these figures is expected to enhance scrutiny of royal income, though detailed breakdowns of income sources or deductions remain undisclosed.

In parallel with the tax disclosure, the annual royal accounts will also present the Sovereign Grant, the public funding that supports the official duties of the household. The grant is set to rise to a record £99.9 million for the 2027‑28 fiscal year, following a temporary increase to cover extensive Buckingham Palace renovations. While the grant funds staff, building upkeep, and travel, it does not provide personal income to the royal family.

The King and Queen Camilla will continue to reside at Clarence House, a decision that maintains public access to Buckingham Palace and underscores a broader effort to modernise the monarchy’s public image. Observers note that the tax revelation, paired with the grant’s upcoming reduction, signals a shift toward greater financial openness and alignment with public expectations for accountability.
