The vast majority of Their Royal Highnesses’ activities are paid for out of The Prince’s income from the Duchy of Cornwall, the private estate which historically has always provided financial support for the Heir to The Throne since it was founded in 1337.

The Prince voluntarily pays tax, at the higher rate of 45 per cent, on this income. He chooses to spend the majority of his after-tax income to support his and The Duchess’s working activities and those of The Duke and Duchess of Cambridge and The Duke and Duchess of Sussex. The income also funds his personal spending.

Public money is used to aid The Prince and The Duchess in specific areas in supporting The Queen as Head of State. These are: security costs; travel when Their Royal Highness fly or go by train to and from official engagements; and property maintenance on royal residences.

These and other financial figures are published every year in the Annual Review.
