There is great diversity to Europe’s tax systems, reflecting the choices of sovereign States with differentiated destinies. Since the Treaty of Rome, the Member States have steadily refused to give up national authority over taxation, with the exception of a minimum level of coordination on value-added tax (VAT). Europe now faces a real risk of a rise in non-cooperative tax strategies, with each country seeking to improve its economic performance at the expense of the others. This kind of aggressive strategy is being fuelled by two factors: on the one hand, a drive for competitiveness (fiscal devaluation), aimed at reducing the tax burden on businesses so as to improve price competitiveness; and on the other, a drive for fiscal advantage, aimed at luring the rarest factors of production to the national territory. On a macroeconomic level, it is difficult to distinguish clearly between these two factors. However, one way of understanding how the European states have improved their position may be to look at how the tax burden on business has evolved in comparison with the burden on households.
