The objective of this paper is to analyze fiscal revenues registered by the European Union member states in order to determine groups with similar fiscal structures, their composition and to identify the similarities that characterize European countries in this respect. The research conducted in this paper is relevant especially for countries as Romania, which is in the process of adopting the European single currency, as is allows us to determine which countries are similar in terms of fiscal structure so that the comparison is carried out mainly with those countries. The analysis of European fiscal structures allows a better identification of tax preferences within the European Union and highlights the types of taxation that would allow leeway in implementing long term fiscal strategies, which could lead to improvements in macroeconomic dynamics registered by each member state and also at Union level.
