The annual tax bill of King Charles III has been disclosed for the first time. This was reported by Qazaqyia.kz citing The Guardian.
The monarch is not liable for tax, but he and his mother before him have been paying it voluntarily since 1993. A two-sentence statement released on 26 June 2026 showed his tax payable amounted to £12.9m in 2024-25, and a slightly smaller sum the year before. Total tax since accession stands at £30m.
The declaration lacked detail: total income, total private fortune, and how much expenses for royal duties reduced the bill are unknown.
According to The Guardian's 2023 'Cost of the Crown' investigation, the king's private wealth (privy purse) is estimated at least £1.8bn. This includes the Duchy of Lancaster (£690m land and property portfolio yielding £25m annual income), as well as cars, jewels, art, and private residences Balmoral and Sandringham. Information on financial investments and their returns is scarce.
Comparisons raise questions. Hedge fund boss Suneil Setiya, also worth £1.8bn, paid £114m in tax – 10 times the king's 2023-24 bill. Musician Ed Sheeran (£410m) paid £20m, author JK Rowling (£975m) paid £47m, and footballer Erling Haaland paid £17m.
The Duchy of Lancaster is exempt from taxes that companies or trusts pay. Capital gains from property sales and rental income accumulate and are reinvested tax-free, allowing the king's wealth to grow faster than his subjects'. The palace says the king voluntarily pays capital gains tax on his private wealth and accounts are externally audited. But no other citizen has such discretion over the tax they choose to pay.
