Harmonization of Corporate Income Tax (CIT) in the EU - Achievements and Challenges

This paper provides a framework of the tax systems of CIT - Corporate Income Tax in the EU. This paper treats the concept of CIT according to the OECD, EU directives and Kosovo legislation. It aims to identify gaps in the current Kosovo legislaton and the tendency to increase the harmonization of the tax systems in EU, especially, in view of the direct taxes. The theory of international tax law counts some methods used in the case of the relocation of the source of income from countries with high tax rate in countries with the lower tax rate. However, determining the level of taxation in this area is the exclusive issue of Member States in harmony with the principle of subsidiarity. With the aim at securing sustainable economic development and growth in the EU, within the framework of their strategy some changes were proposed regarding the elimination of all legal and fiscal barriers that hinder the full integration of the national systems of member states into the common market. The CCCTB initiative is considered a major step towards aligning the EU tax systems. So, the purpose of this article is to demonstrate the level of harmonization of the tax systems in EU, using the comparativ, empirical, normativ and logical methods, to conclude the role of CIT in the tax systems
