On Thursday, King Charles will become Britain’s first head of state to make public their personal tax bill. Buckingham Palace has suggested it is part of efforts to “modernise and evolve”, but it should more specifically be understood as an attempt at transparency following ongoing questions around the finances and spending of Andrew Mountbatten-Windsor. Charles’s tax bill will include what he pays on profits from the Duchy of Lancaster, any personal investments or savings and his private estates. Charles also disclosed his tax filings when he was Prince of Wales. In 2022, he paid 25% of the £23m made in duchy profit after deducting official costs. Although Charles is not legally required to pay income tax, he does so voluntarily.
