The 2014 edition of Taxation Trends in the European Union is the eighth issue of the report in its current form. The objective of the report remains unchanged: to present a complete view of the structure, level and trends of taxation in the Union over a medium- to long-term period. Taxation is at the heart of citizens' relationship with the State. It is not only government experts and academics, but also many citizens that ask the European Commission questions about tax levels in the EU and on how Member States compare with each other; this report, published annually, is one way of answering them. Much work has gone into making sure that the data it contains are accurate and comparable across countries. The methodology to ensure this was developed jointly by statisticians from Eurostat and economists from the Directorate-General for Taxation and the Customs Union, who have drafted the report. In addition, experts from national Statistical Offices and from the Ministries of Finance of all countries covered have actively contributed by supplying data and comments; we would like to express our thanks for their valuable suggestions and help. The report provides data and analysis for the European Semester, as the proper functioning of tax systems is a key prerequisite for economic growth. The data on the tax burden in the various Member States can thus be used as an input for the formulation of the Country-Specific Recommendations on tax reforms that are announced at the end of the European Semester. In addition to the analysis of Europe-wide trends in Part I, the report also includes a Part II with Country Chapters, covering each EU Member State plus Iceland and Norway. The Country Chapters contain a discussion of tax revenue trends, as well as a description of the main characteristics of each country's tax system. -- EU Bookshop.
