Prince William has officially become one of the wealthiest members of the British royal family after newly published financial accounts revealed that the Prince of Wales now controls assets worth an estimated £1.2 billion through the Duchy of Cornwall.
The latest disclosures have also placed William ahead of his father, King Charles III, whose personal fortune is estimated at around £640 million, according to the latest Sunday Times Rich List.
The revelation marks a significant financial milestone for the future king and highlights the enormous value of the historic Duchy of Cornwall estate, which automatically passes to the heir to the British throne.
According to the annual Sovereign Grant financial accounts, Prince William inherited control of the Duchy of Cornwall immediately after the death of Queen Elizabeth II in September 2022, when King Charles ascended the throne and William became the new Prince of Wales.

The Duchy of Cornwall is one of Britain’s oldest and most valuable landed estates. Established in 1337 by King Edward III, it was created specifically to provide an independent income for the heir apparent to the throne.
Today, the estate includes thousands of hectares of farmland, forests, commercial properties, residential buildings, rivers, coastline and investment assets spread across England and Wales.
The newly released accounts estimate the Duchy’s overall asset value at approximately £1.2 billion.
While Prince William does not personally own the estate in the traditional sense and cannot sell its assets, he receives the annual profits generated by the Duchy to fund his official duties, charitable activities and support for his family.
During the 2025–26 financial year, William received approximately £21.6 million in private income from the estate.
The financial report also revealed that the Prince of Wales has voluntarily paid substantial taxes on his income.
According to the accounts, William paid £7.76 million in income and capital gains tax during the 2024–25 financial year.
Combined with taxes paid since becoming Prince of Wales, his total tax contributions now exceed £20 million.
These voluntary disclosures form part of ongoing efforts by senior members of the Royal Family to improve transparency regarding royal finances.
Although the British monarchy is exempt from certain tax obligations, both King Charles and Prince William have chosen to pay income tax voluntarily on relevant earnings for several years.
The publication of the accounts also highlighted another notable decision by Prince William.
It confirmed that he will no longer personally benefit from the estimated £1.5 million annual rental income generated by the former Dartmoor Prison site.
The move reflects William’s stated intention to modernise aspects of the Duchy’s operations while placing greater emphasis on public benefit and environmental sustainability.
Meanwhile, separate announcements concerning the Royal Family also revealed that King Charles III and Queen Camilla will not relocate to Buckingham Palace after the completion of its extensive refurbishment programme.
The historic palace has been undergoing a £370 million renovation project aimed at modernising infrastructure, improving safety systems and preserving the iconic building for future generations.
Instead of moving into Buckingham Palace, Charles will continue to use Clarence House as his primary London residence throughout his reign.
Buckingham Palace will remain the administrative headquarters of the monarchy, hosting official receptions, investiture ceremonies, state occasions and other royal events.
A palace spokesperson explained the decision by saying that although the King has great affection for Buckingham Palace, Clarence House will remain his preferred home.
“His Majesty retains huge affection for Buckingham Palace and a deep respect for its role in royal and public life. It will be a buzzing hive of royal activity in every other way,” the spokesperson said.
The latest financial disclosures have generated widespread interest because they offer one of the clearest pictures yet of the wealth associated with the British monarchy.
While King Charles remains one of Britain’s wealthiest individuals through his personal investments, inherited assets and royal holdings, the enormous value of the Duchy of Cornwall now places Prince William in control of even greater financial resources.
William and Catherine, Princess of Wales, were recently seen attending the prestigious Royal Ascot horse racing event in Berkshire, where they greeted well-wishers after arriving by carriage.
The couple continues to carry out a growing number of royal engagements as Prince William prepares for his future role as king.
The publication of the financial accounts provides further insight into how the Royal Family manages its finances and demonstrates the significant responsibilities that accompany control of one of Britain’s oldest royal estates.
With assets valued at around £1.2 billion and an annual income exceeding £21 million, Prince William now oversees one of the most valuable private estates in Europe, cementing his position as the wealthiest senior member of the Royal Family and reinforcing his central role in the future of the British monarchy.
