The article analyzes the historical periods of development of the taxation system in Soviet times and during the independence of Ukraine. The stages of transformation of the country's taxation system and the deduction of the development of the national taxation system are outlined.

The preconditions of each of the specified stages of realization of transformation of system of the taxation are analyzed. Among the key preconditions for transformational changes in certain periods are: rapid deterioration of key macroeconomic indicators, implementation of laws and regulations on the establishment of the tax police and the transformation of the State Tax Administration into a central executive body as a controlling body for legal entities and individuals, changes in the composition and mechanisms of tax calculation, chaos and invalidity of the system of tax benefits, changes in the legalization of the wage fund and in the system of compulsory state social insurance. The functions of taxes as defining concepts of formation of the tax system of the country that were in each period defined above are investigated. The types and role of tax relief as a tool of state tax regulation and stimulation of socio-economic processes are considered. The assessment of the process of transformation of the tax system identified the existing criteria for reform, including diversity, complementarity and consistency, compromise and evolution, the depth of transformation and innovation of the tax system of Ukraine.
