Prince William is now richer than King Charles, with the Duchy of Cornwall valued at £1.2 billion, according to newly published accounts. The documents also reveal that William has paid more than £20 million in tax since becoming Prince of Wales.
Duchy of Cornwall Assets and Income
The Duchy of Cornwall, inherited by William when he became heir to the throne nearly four years ago, now holds assets worth £1.2 billion. In the 2025-26 financial year, William received a private income of £21.6 million from the Duchy, as shown in the latest accounts.
In contrast, King Charles's personal fortune, as listed in the Sunday Times Rich List, stands at £640 million—an increase of £30 million from the previous year.
Tax Payments Revealed
In a move toward greater transparency, both King Charles and Prince William have disclosed their private tax payments. William contributed £7.76 million in income and capital gains tax in 2024-25 and £8.34 million in 2023-24, bringing his total tax payments since becoming Prince of Wales to over £20 million.
Dartmoor Prison Rent Redirected
Prince William has decided to no longer personally benefit from the £1.5 million annual rent generated by the abandoned Dartmoor Prison. The prison, located on Duchy of Cornwall land, has been empty since July 2024 due to high levels of radon gas. Starting in 2026-27, the rental income will be redirected to a community-led regeneration fund for Princetown, the nearby rural community.
William's private secretary, Ian Patrick, stated: "Prince William knows that for many people in Princetown, the prison has long been part of the fabric of the community. Its closure has created genuine uncertainty, not just about jobs and businesses, but about the future of the town itself. The duke felt strongly that, while those questions remain unanswered, the benefit of this income should remain in the community, helping local people shape that future."
Household Staff and Diversity
Kensington Palace reported that the number of staff employed by William and Kate's household has increased to 74, up from 68. Diversity figures show that 14.9% of staff are from an ethnic minority background, compared to 13.2% the previous year. Additionally, 73% of Kensington Palace staff are female, and 27% are male.
