Theoretical aspect of modern state tax policy

The relevance of the research topic is caused by the priority of the effective tax policy development in Russia, which is primarily connected with the search for new tools and methods. To ensure a sufficient level of revenue base of any budget level of the budget system of the Russian Federation, we need an effective tax policy of the country and optimal financial management in the public sector. In this regard, as well as changing economic processes in society, there is a need to reform the existing tax policy of the Russian Federation and, therefore, to increase the efficiency of financial management in the public sector. Effective tax policy is developed on the basis of proven and accepted theoretical provisions. The work reveals and supplements the goals, objectives, functions and principles of modern state tax policy. The study was based on a comparison of existing theoretical approaches to the essence of the state’s tax policy, the identification of new tasks, relevant functions, and changing principles.
