The article investigates the tax policies of the new EU Member States before and during the acute aggravation of the global economic conjuncture (2008-2009), as well as during the fragile equilibrium of the post crisis revival. Based on comparative analysis, the authors establish that, despite a certain difference in orientation, the com-mon features of the tax reforms in the EU post-socialist countries, Cyprus and Malta are ensuring a reliable financial base for the state functioning through the active use of VAT fiscal potential and well considered ap-proach to the regulating effect of corporate income tax on the economic processes, as well as expansion of the area of use of privileged social mechanisms in the taxation of the individuals’ incomes. The authors provide various conclusions as to the initiatives of the State Tax Service of Ukraine concerning the reform of Ukraine’s tax system in the context of European experience

Tax policy and changes in taxation in the EU due to the strengthening of the integration processes are investigated. The features of tax harmonization development, national tax systems and tax convergence in the EU are analyzed.
The authors found out that intensification of integration processes resulted in: 1) gradual "convergence" of indirect taxation mechanisms in the EU (also had a significant impact on the distribution of the VAT, its reformation and establishment as one of the main sources of tax revenue); 2) implementation, by a number of EU members states, of the strategy of active tax liberalization to encourage foreign investment and thereby reduce their backlog in the level of economic development from the countries that initiated the integration, which resulted in increased difference in the taxation pattern between the EU member states. The following observations were made: on the one hand, improvements in harmonization of VAT and specific excises took place that facilitated the strengthening of fiscal role and convergence between the shares of indirect taxes in GDP in the EU, and, on the other hand, establishment of lower tax ratio than the EU-15 average by Ireland and most post-socialist EU member states.
Among the constraints to tax harmonization and tax convergence in the EU, the major are different national possibilities to accumulate direct taxes and social contributions, and differences in the institutional environment for the transformation of taxation in the "old" and "new" member states. However, a gradual reduction of the difference in economic development in the EU and progress in the development of market economy in the post-socialist countries with the implementation of similar tax reforms by national governments to address such problems may promote further tax harmonization and the "convergence" of the tax systems in the EU.
