The monarch is set to publicly disclose his complete tax records in a groundbreaking move for the royal family. King Charles will unveil the total sum of taxes he pays, encompassing income from personal wealth, investments, and specific Capital Gains tax, marking the first instance of a British monarch doing so.
Buckingham Palace announced that this unprecedented action aims to showcase the monarchy’s commitment to “modernize and evolve” under King Charles’ reign. The King had previously made his tax returns public during his time as the Prince of Wales and overseeing the Duchy of Cornwall.
Upon ascending the throne, Prince William inherited the Duchy of Cornwall and opted to cease the practice of disclosing his tax returns, a decision that has drawn scrutiny. The King’s choice to reveal his tax affairs as monarch is expected to increase pressure on Prince of Wales to follow suit.
A spokesperson for the King stated that Charles’s decision aligns with Buckingham Palace’s goal of enhancing transparency around the monarchy’s finances by issuing a new report on the matter. The disclosed tax information will encompass the King’s total tax payments, including revenues from the Duchy of Lancaster, investments, trading profits, and earnings from his properties and savings.
The Duchy of Lancaster estate, comprising land, investments, and various properties, provides the King with an annual income, which in the 2024/2025 fiscal year amounted to £26.8 million. The detailed tax information for the 2024-25 financial year will be made public, alongside additional reports on royal finances. The tax details for 2025-26 will be released next year once the audit process is completed.
However, the information will be presented as a lump sum without individual breakdowns of financial contributions. The Palace emphasized that the decision to disclose tax information was at the King’s request, in line with the changes implemented since his accession.
Meanwhile, Prince William has chosen to withhold more financial details compared to his father, raising questions about transparency. The upcoming report aims to provide a comprehensive overview of royal finances, enhancing accessibility and historical context.
The Sovereign Grant, introduced in 2012/13, consolidates financial support for the monarch, encompassing expenses for royal residences, travel, and staff costs. The Sovereign Grant report, to be released next week, will detail the royal family’s public funding, including the percentage of profits from the Crown Estate allocated to the monarchy.
King Charles voluntarily pays the highest UK income tax rate on his Duchy of Lancaster income, further reflecting a commitment to financial transparency. Buckingham Palace emphasized ongoing modernization and evolution within the royal household to enhance accountability and understanding of its operations.
