Daňové systémy v kontextu evropského vnitřního trhu

Formation of a common single market without distortions is one of the main priorities during the integration process of the European Union. For this purpose it is necessary to coordinate activities of all the Members throughout the entire Community ant it should lead to European integration and convergence. The main aim of this work is to verify European formation of the common single market throughout European tax policy in other words, through the convergence of the tax burden. Secondary aim is focused on the question of what impact do convergence of tax mixes and tax competition have on the convergence of the taxation in the EU. For this purposes data from the years of 1965 - 2011 in combination with methods of Beta Convergence, Sigma Convergence and panel regression analysis with fixed effects are used. Results confirm the tax systems convergence and its speed not only in the area of total tax burden but also in tax mixes, implicit tax rates and some statutory tax rates. Panel regression analysis with fixed effects subsequently confirmed the positive impact of the convergence of nearly all tax mixes parts and tax competiton on the total tax burden convergence. The highest impact on the tax convergence was verified at the tax competition and property taxes. All models accomplish diagnostic tests and are econometrically robust. It was confirmed the European Union has been fulfilled its primary aim through the tax policy and under established assumptions the highest impact on tax convergence have tax competition and property taxes.
