Since January 2017, Ukraine has joined the OECD's Inclusive Framework and committed itself to implementing the BEPS Minimum Standard. The national tax system is similar in structure to the tax systems of developed countries. At the same time, the country's recognition of generally accepted standards for combating aggressive tax planning requires significant adaptation of the legal framework. Monitoring of the legislative process of implementing the BEPS Action Plan is an important area of further development of state regulation in the tax area and an effective means of achieving the proper quality of tax legislation and creating a modern and efficient tax system. The regulatory assessment of the state of national legislation will facilitate a detailed understanding and analysis of possible positive effects, achievement of results in the fight against tax evasion and base erosion, and avoidance of legal conflicts and contradictions. Monitoring the legislative process of implementing the BEPS Action Plan measures allows us to identify the necessary areas for improving the national legislative system and track the positive and negative effects of the application of legislative norms. Monitoring of regulatory legal acts is a tool for the development of future-oriented legislation, as it involves the study of legislation to obtain information necessary for assessing, forecasting, controlling and formulating recommendations for improving the regulatory framework and ensuring its optimal condition. As a member of the OECD Inclusive Framework, Ukraine has implemented the BEPS Action Plan Minimum Standard through significant adaptation of the national tax legislation and its approximation to the provisions of international tax instruments. Monitoring of the legislative process of implementing the BEPS Action Plan is an important area of development of state regulation in the tax area and an effective means of achieving the proper quality of national tax legislation and further development of an effective tax system.
