By law, Charles ​is not obliged to pay income ​tax, capital gains tax or inheritance tax on ⁠what he received from Queen Elizabeth, but ​Charles has voluntarily agreed to pay income tax ​and capital gains tax when he sells private assets.

Details will come as part of the annual royal accounts due ​for release on Thursday.

Charles receives personal income from ​land, private estates and investments on top of the £132 million ($175 ‌million) ⁠he received from the government in the 2025/26 tax year to support royal duties.

A Buckingham Palace spokesperson said the move aimed to “encourage wider ​understanding of ​our accountability”.

Charles ⁠provided information on his tax payments when he was Prince of Wales ​and intends to continue to do ​so ⁠in future years as king, the palace said.

The British parliament’s Public Accounts Committee launched an inquiry ⁠into residential ​property arrangements provided to ​members of the royal family last year.
