King Charles paid £12.9 million in tax for 2024-25, up from £11.7 million the prior year, with totals exceeding £30 million since accession in 2022. The payments derive from Duchy of Lancaster revenue of £25.2 million and follow a voluntary arrangement begun by Queen Elizabeth II in 1993. Combined payments with Prince William exceed £50 million, while the Crown Estate recorded £1.2 billion in profit, two-thirds from offshore wind fees.
