Only the Queen receives the benefit of the Civil List...The Duchess of Cornwall, Prince William or Prince Harry are funded from a Parliamentary Annuity, the amount of which is fully refunded by The Queen to the Treasury. The Queen is permitted to claim this amount as a deduction against her gross income from personal investments and other sources - the net amount, after deductions, is subject to normal income tax...
