Kingdom; that was the first year she was not among the Sunday Times Rich List's top 300 most wealthy since the list began in 1989. She was number one on the list when it began in 1989, with a reported wealth of £5.2 billion, which included state assets that were not hers personally, (approximately £ in today's value). Parliamentary annuities The Duke of Edinburgh received a parliamentary annuity of £359,000 per year from the Treasury. In the past some other members of the British royal family also received funding in the form of parliamentary annuities. The Civil List Act 1952 provided for an allowance to Princess Margaret as well as allowances to the queen's younger children among others. The Civil List Act 1972 added further members of the royal family to the annuity list. By 2002 there were eight recipients of parliamentary annuities, all receiving a combined total of £1.5 million annually. Between 1993 and 2012 the Queen voluntarily refunded the cost of these annuities to the Treasury. The Sovereign Grant Act 2011 abolished all of these other than that received by the Duke of Edinburgh. Subsequently, the living costs of the members of the royal family who carry out official duties, including the Princess Royal, the Duke of York, and the Earl and Countess of Wessex, have mainly been met through the Queen's income from the Duchy of Lancaster. Taxation The Crown has a legal tax-exempt status because certain Acts of Parliament do not apply to it. Crown bodies such as The Duchy of Lancaster are not subject to legislation concerning income tax, capital gains tax or inheritance tax. Furthermore, the Sovereign has no legal liability to pay such taxes. The Duchy of Cornwall claims a Crown exemption meaning the Prince of Wales is not legally liable to pay income or corporation tax on Duchy revenues, although this has been disputed. The prince voluntarily pays income tax, although questions have been raised about expense claims that would limit his tax liability. A "Memorandum of Understanding on Royal Taxation" was published on 5 February 1993 and amended in 1996, 2009 and 2013. It is intended that the arrangements in the memorandum will be followed by the next monarch. The memorandum describes the arrangements by which the Queen and the Prince of Wales make voluntary payments to the HM Revenue and Customs in lieu of tax to compensate for their tax
