Taxation in the United Kingdom may involve payments to a minimum of three different levels of government: the central government (Her Majesty's Revenue and Customs), devolved national 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 and Wales, Council Tax and increasingly from fees and charges such as those from 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.
