King Charles is set to make history by becoming the first British monarch to publish his full personal tax returns, marking a major step in his efforts to modernise the monarchy and increase public transparency.
Buckingham Palace confirmed that the King will disclose the total amount of tax he pays, including income from personal wealth, investments, estates, savings and profits generated through the Duchy of Lancaster. The move is unprecedented and reflects the King’s desire to ensure the Royal Family continues to evolve in line with modern expectations.
The Duchy of Lancaster, a private estate consisting of land, property, commercial investments and other assets, provides the monarch with a significant source of income. For the 2024 to 2025 financial year, the Duchy generated £26.8 million.
Charles previously published details of his tax affairs while serving as Prince of Wales and managing the Duchy of Cornwall. However, that level of transparency ended after Prince William inherited the Duchy upon Charles’s accession to the throne in 2022. The King’s latest decision is likely to increase pressure on William to reveal more about his own financial arrangements.
Buckingham Palace said the publication of the King’s tax information forms part of a broader effort to improve public understanding of royal finances. A new report, due to be released next week, will explain how the monarchy is funded and how royal finances operate within Britain’s constitutional framework.
A Palace spokesperson said the decision was made at the King’s express request and forms part of the changes introduced since the beginning of his reign. The spokesperson added that the aim is to provide greater clarity and accessibility while placing royal finances in their historical and constitutional context.
The King’s tax details for the 2024 to 2025 financial year will be released as a single overall figure rather than a detailed breakdown of individual income sources and tax payments. His tax information for 2025 to 2026 will be published next year after the completion of the audit process.
The announcement comes amid growing calls around the world for greater transparency from public figures and institutions. Several European royal households, including those in Sweden, Norway and the Netherlands, already provide extensive information about public funding and official spending. Advocates of greater openness argue that increased financial disclosure helps strengthen public trust and accountability.
The British monarchy receives public funding through the Sovereign Grant, established under the Sovereign Grant Act 2011. The grant supports the monarch’s official duties and is financed through profits generated by the Crown Estate, while personal income and private assets remain separate.
Royal observers say the King’s decision represents one of the most significant transparency measures introduced by the monarchy in recent decades and could set a new benchmark for future generations of the Royal Family.
