King Charles III has paid more than 34 million euros in taxes since he ascended the throne next to the death of Queen Elizabeth II, as revealed this Thursday night by Buckingham Palace, in what a spokesperson has described as "an unprecedented exercise in transparency". It is the first time the British royal household has published the monarch's personal tax bill. Since 1993, the sovereigns have voluntarily paid taxes on income and capital gains. Legally, however, they are not obliged to.
