King Charles Paid £5.6m in Tax, But Questions Remain
King Charles voluntarily paid £5.6 million in income tax for the 2025-26 financial year, according to figures released by Buckingham Palace. This marks a slight increase from the previous year's £5.5 million, reflecting higher income from the Duchy of Cornwall and the Sovereign Grant. However, the palace continues to withhold detailed breakdowns of the monarch's personal wealth and spending, prompting criticism from transparency campaigners.
How the Tax Bill Is Calculated
The king's tax payments are voluntary, as the monarch is exempt from compulsory taxation under a convention established in 1992 by Queen Elizabeth II. The £5.6m covers tax on income from the Duchy of Cornwall, a private estate that funds the heir to the throne, and on the Sovereign Grant, which is the taxpayer-funded allowance for official duties. The palace said the figure includes capital gains tax and tax on investment income, but did not specify the exact proportions.
According to the palace, the king's total income from the Duchy of Cornwall rose by 12% to £28.8 million, driven by increased rental income from commercial and residential properties. The Sovereign Grant remained flat at £86.3 million, as it is linked to the profits of the Crown Estate, which fell slightly due to lower property valuations.
What Remains in the Dark
Despite the disclosure, several aspects of royal finances remain opaque. The palace does not reveal the king's personal net worth, which is estimated by Forbes at $2.1 billion but is not independently audited. There is also no breakdown of how the Sovereign Grant is spent, with the palace only providing a high-level summary of categories such as travel, staff salaries, and property maintenance.
“The royal family should be subject to the same transparency standards as other public bodies,” said John Smith, director of the campaign group Republic. “Without a full audit, we cannot be sure that taxpayer money is being used efficiently.” The palace defends its approach, stating that the voluntary system balances privacy with accountability.
Impact on the Monarchy's Reputation
The disclosure comes amid ongoing debates about the monarchy's cost to the public. Polls suggest that support for the monarchy remains high, but younger generations are increasingly questioning its relevance. The palace's decision to release tax figures annually is seen as an attempt to preempt criticism, but critics argue that the lack of detail undermines trust.
Buckingham Palace said it would continue to review its financial reporting practices, but stopped short of committing to a full independent audit. The next annual report is expected in July 2027.
