As the Sovereign Grant accounts are published, the monarchy’s fiscal footprint comes under the microscope. Here are three peculiarities that caught my eye – and should trouble any taxpayer with a calculator.
First, the King pays tax voluntarily. Let that sink in. While the rest of us have the Inland Revenue as an inescapable creditor, Charles III opts into a bespoke arrangement. The Royal Household says he pays income tax and capital gains tax at the prevailing rates. But there is no legal compulsion. This is a gentleman’s agreement, not a statutory duty. In an era of fiscal tightening, that feels like an anachronism.
Second, the tax bill is partly paid from public funds. The Sovereign Grant, which funds official duties, is itself drawn from the Crown Estate profits. So the Treasury gives the Palace money, and then the King voluntarily pays some of it back. This circular flow looks neat on a spreadsheet, but it obscures the true cost. The net contribution to the exchequer is far smaller than the headline figures suggest.
Third, the King does not pay inheritance tax. Assets passed from the Sovereign to the heir are exempt, under a 1993 agreement with the Major government. This was designed to prevent the Royal Collection from being broken up. But it also means that vast wealth – including art, palaces, and the Duchy of Lancaster – escapes the 40% charge that ordinary families face. The rationale may be constitutional, but the optics are poor when the state is raising taxes elsewhere.
These facts emerge as gilt yields remain elevated and the Bank of England struggles to tame inflation. Every pound of public spending now carries an opportunity cost. The Sovereign Grant for 2025-26 is set at £86.3 million, equivalent to the cost of 1,700 nurses. When markets are jittery about fiscal credibility, even the Crown should expect scrutiny.
The Palace argues that the monarchy generates a net economic benefit through tourism and soft power. That may be true. But the lack of transparency on the King’s tax affairs feeds a perception of privilege. In a city like London, where capital flight is a constant worry, such perceptions matter. Investors watch for signs of fiscal recklessness. A tax-exempt sovereign does little to reassure them.
Let me be clear: I am not a republican. The monarchy provides stability. But stability requires trust, and trust requires openness. The three facts above suggest the current arrangement is built more on custom than clarity. As the cost of borrowing rises and the deficit widens, that is no longer enough.
The Treasury should formalise the King’s tax obligations. Make them statutory, not voluntary. End the inheritance tax exemption. And publish a full account of the sovereign’s net fiscal contribution. That would be a small step toward the accountability that every taxpayer deserves.
Until then, the King’s tax bill remains a curiosity. A curiosity that costs us all.
