The tax system has never been united in France. There have always been an extreme diversity in collection, the base, the rates and the nature of the taxes. Until 1789, taxes were collected by the state, the church and lords. After the French revolution, taxes consisted of taxes on wealth and on incomes. The current tax system was shaped during the 20th century. All taxes created under the French Revolution were abolished, the last being the patentes, abolished in 1974. Whereas taxation aimed at assuring "the maintenance of the public force" and "the expenditures of the administrations"(Déclaration des droits de l'homme et du citoyen de 1789), taxation is now aiming at assuring efficient public services and a fair distribution of the wealth and the income.
