King Charles III is about to do something no British monarch has done before: putting his personal tax bill in front of the public. The figure is due on Thursday, 25 June, when the royal household publishes its annual financial accounts, making the 77-year-old the first UK head of state to reveal what he pays the taxman.
The disclosure covers the 2024-25 financial year. His 2025-26 tax details will follow next year, once those accounts have been audited, Buckingham Palace said.
