Charles will publish his financial details as his royal household seeks to increase “clarity and accessibility” around the monarchy’s finances by producing a new report on the subject. The decision by the King, who has spent the week at Royal Ascot, is in contrast to the Prince of Wales, who has not disclosed the tax he has paid since becoming heir to the throne. Now, a royal commentator has heaped praise on the monarch for his bid for transparency when it comes to royal finances.

The Telegraph’s Deputy Royal Editor, Victoria Ward, said that financial transparency “has long been considered a weak spot for the monarchy” and that Charles has made a “valiant attempt at turning the tide”.

Ms Ward added that the decision has always been a “work in progress” for the monarch, who inherited an institution from his mother, the late Queen Elizabeth, whose “clandestine operations were deeply rooted in the decade-old mantra of 'never complain, never explain’”.

But the palace is said to hope that Charles’s actions will “clarify and contextualise” and provide a fuller and more accessible picture.

Ms Ward said: “Both the King and his heir will hope that by letting in a chink of light, they will put to bed some of the conspiracy theories, allay suspicions and present the monarchy as a modern institution that has nothing to hide”.

A Buckingham Palace spokesperson said: “While this is the first time a monarch has shared this personal tax information, you may recall it was similarly released by His Majesty when he was Prince of Wales.

“The decision to do so as Sovereign has come at the express wish of the King himself, as part of the adaptations carried across since accession.”

Next week, the King’s total personal tax information for the 2024-25 financial year will be published, alongside other reports on royal finances.

His 2025-26 tax details will be released next year once the audit is completed.
