Prince William faces an income tax bill of up to £7 million annually, placing him among the top 0.002 percent of UK taxpayers. He pays the highest rate of 45 percent on his earnings, primarily from the Duchy of Cornwall.
Duchy of Cornwall: Key Income Source
The Duchy of Cornwall, a private estate valued at approximately £1.1 billion, generates more than £20 million each year for the Prince of Wales. Established in 1337 by King Edward III to support his son, Prince Edward, the estate provides substantial revenue.
In the 2023-24 financial year, William’s first overseeing the Duchy, he received £23.6 million. Around £13.5 million of this amount qualifies as taxable income, resulting in a tax liability estimated between £5 million and £7 million.
Tax Transparency Concerns
Questions about tax transparency have grown following reports that the Duchy of Cornwall and Duchy of Lancaster have earned millions by leasing land to public entities, including the NHS, armed forces, and schools. William has not publicly disclosed his tax payments in recent years.
His father, King Charles III, voluntarily paid £5.9 million in income tax on Duchy earnings during his final year as heir apparent in 2021-2022. William adopts a comparable approach, contributing at the 45 percent top rate.
Royal Tax Arrangements
A 2013 agreement between the late Queen Elizabeth II and the Treasury exempts the monarch from income tax, capital gains tax, and inheritance tax. Similarly, William holds no legal obligation to pay income tax on Duchy income, though he voluntarily complies with the highest rate.
