There are a huge number of local taxes. The most important are the direct taxes. The local direct taxes are the oldest taxes in the French tax system, as they succeed to direct contributions that were created in 1790 and 1791 as taxes collected by the central government then transferred to local authorities upon the tax reform of 1917. Local taxes are levied by the state for local authorities (regions, departments, municipalities, local public institutions). There are four main direct taxes ("taxe foncière sur les propriétés bâties", "la taxe foncière sur les propriétés non-bâties", "taxe d'habitation" and "taxe professionnelle"). The rates are set by the territorial assemblies (regional or municipal councils) when they vote their annual budget. However, rates can not exceed certain limits set by the state. The tax bases are established by the state. There are many permanent or temporary exemptions. In 2006, the revenue from the four major local direct taxes amounted to €60.2 bn. Apart from these four main taxes, there are many other taxes. Direct taxes include the "taxe pour frais de chambres d'agriculture" (expense of the chambers of agriculture), the "taxe d'enlèvement des ordures ménagères" (garbage collection), and the "taxe sur les pylônes". Indirect taxes are taxes applying to spring water, mines, spectacles, advertising, navigation, electricity, pollution and workplace.
