King Charles has announced his decision to disclose his complete personal tax details as part of an initiative to enhance transparency surrounding royal finances. Today, the King will make public his annual tax payment details, becoming the first monarch to do so.
According to a palace insider, the King is determined to release the tax information for the first time, amid increased scrutiny on the Firm’s financial affairs. Charles will disclose the total tax amount he pays, encompassing income from personal wealth, investments, and specific Capital Gains tax.
When questioned about the expansion of the palace’s financial briefing, a Palace aide cited that the King believed it was the appropriate action to take. The aide expressed the King’s hope that this move would significantly aid the public in understanding the operations of the Sovereign Grant and Duchy of Lancaster, the King’s estate, as well as his private income sources.
Private funds, including proceeds from investments, trading profits, revenues from his private estates of Balmoral and Sandringham, and personal savings, constitute part of the King’s finances. The Duchy of Lancaster estate, comprising land, investments, and various properties, provides the King with an annual income, which amounted to £26.8 million in 2024/2025. Charles willingly pays the top UK income tax rate (45%) on his Duchy of Lancaster income.
Designed to offer the reigning monarch an independent income source historically known as the Privy Purse, the Duchy of Lancaster estate serves official and personal expenditures, including those of other Royal Family members.
The King’s complete tax information for the 2024-25 fiscal year will be disclosed today alongside other reports on royal finances. However, details of his 2025-26 tax payments will be released next year post their audit completion.
The announcement of Charles’ tax disclosure came last week, with Buckingham Palace highlighting the extensive details on publicly-funded expenditures and other operational data in the annual Sovereign Grant Report. The Palace aims to improve transparency further and enhance public understanding of Royal finances by introducing additional measures aligned with public service priorities.
By disclosing his tax information, King Charles follows a practice he initiated as Prince of Wales while overseeing the Duchy of Cornwall, now passed on to Prince William.
