💸 Royal Transparency: King Charles and Prince William Disclose Millions in Unprecedented Tax Reveal
In a monumental shift for the British monarchy, King Charles III has made history as the first British sovereign to publicly release his personal tax bill. The landmark disclosure from Buckingham Palace reveals that the King has handed over more than £30 million to HM Revenue and Customs (HMRC) since ascending the throne, placing him firmly among the top 100 taxpayers in the United Kingdom.
The Crown Caves to Transparency
The decision to publish the figures came from a personal directive by King Charles himself, who is reportedly determined to bring clarity to royal finances amidst heightened public scrutiny. According to the audited accounts, the King paid over £12.9 million in income and capital gains tax for the 2024/25 financial year, following an £11.7 million payment the previous year.
Following his father’s lead, Prince William has also abandoned his previous stance on financial secrecy. As the heir to the throne, the 44-year-old Prince of Wales disclosed that he has paid more than £20 million to HMRC since taking over the Duchy of Cornwall. His individual tax payments totaled £7.76 million for 2024/25 and £8.34 million for 2023/24.

Inside the Billion-Pound Duchy of Cornwall
Prince William’s vast private income is generated by the Duchy of Cornwall—a massive billion-pound landed estate sprawling across 51,800 hectares and 19 counties. Last year, the estate yielded a net surplus of £21.6 million. While William voluntarily pays the highest rate of income tax on this surplus after official expenditures are deducted, palace aides still refuse to disclose what those official expenses entail.
However, the accounts do highlight Prince William’s aggressive strategy to modernize the estate:
-
The Highgrove Lease: In a humorous twist of royal bureaucracy, William functions as his own father’s landlord, charging King Charles £503,711 in rent last year for his beloved Highgrove estate in Gloucestershire.
-
The Dartmoor Prison U-Turn: Following intense public outcry regarding a £1.5 million annual rent deal for the abandoned Dartmoor Prison—which has sat empty since July 2024 due to toxic radon gas levels—William has officially directed that the funds be diverted entirely into local community regeneration.
-
Land Sell-Off Vow: The Prince has pledged to sell off 20% of the Duchy’s landholdings over the next decade to aggressively reinvest the capital into sustainable infrastructure and affordable community housing.
The True Cost of ‘The Firm’
The annual Sovereign Grant Review underscored an incredibly demanding schedule for the Royal Family, who clocked a combined total of 2,273 official engagements over the past year. Furthermore, the monarchy successfully opened its palace doors wider than ever, hosting 827 events for 97,000 guests, while welcoming over 700,000 paying tourists.
While anti-monarchy groups like Republic have slammed the government-funded Sovereign Grant—which temporarily rose to £132.1 million to fund the final stages of the Buckingham Palace renovations—royal officials promise the grant will drop back to a flat £100 million for the next five years.
Tax experts point out that while these voluntary disclosures normalize the royals as high-earners, the family still enjoys extraordinary systemic privileges. The Duchies of Lancaster and Cornwall remain completely exempt from corporation tax, and the vast wealth of the Crown passes seamlessly from one generation to the next entirely free from the UK’s standard 40% inheritance tax.
