Taxation in the United Kingdom may involve payments to at least three different levels of government: central government (HM Revenue & Customs), devolved governments and local government. Central government revenues come primarily from income tax, National Insurance contributions, value added tax, corporation tax and fuel duty. Local government revenues come primarily from grants from central government funds, business rates in England, Council Tax and increasingly from fees and charges such as those for on-street parking. In the fiscal year 2014–15, total government revenue was forecast to be £648 billion, or 37.7 per cent of GDP, with net taxes and National Insurance contributions standing at £606 billion. History A uniform Land tax, originally was introduced in England during the late 17th century, formed the main source of government revenue throughout the 18th century and the early 19th century. Napoleonic wars Income tax was announced in Britain by William Pitt the Younger in his budget of December 1798 and introduced in 1799, to pay for weapons and equipment in preparation for the Napoleonic Wars. Pitt's new graduated (progressive) income tax began at a levy of 2 old pence in the pound (1/120) on annual incomes over £60 (equivalent to £ as of ), and increased up to a maximum of 2 shillings (10 percent) on annual incomes of over £200. Pitt hoped that the new income tax would raise £10 million, but receipts for 1799 totalled just over £6 million. Income tax was levied under five schedules. Income not falling within those schedules was not taxed. The schedules were: Schedule A (tax on income from United Kingdom land) Schedule B (tax on commercial occupation of land) Schedule C (tax on income from public securities) Schedule D (tax on trading income, income from professions and vocations, interest, overseas income and casual income) Schedule E (tax on employment income) Later, Schedule F (tax on United Kingdom dividend income) was added. Pitt's income tax was levied from 1799 to 1802, when it was abolished by Henry Addington during the Peace of Amiens. Addington had taken over as prime minister in 1801. The income tax was reintroduced by Addington in 1803 when hostilities recommenced, but it was again abolished in 1816, one year after the Battle of Waterloo. Considerable controversy was aroused by the malt, house, windows and income taxes. The malt tax was easy to collect from brewers; even after it was reduced in 1822,
