The main provisions for improving the existing theoretical foundations and practical measures of the tax planning system at an enterprise are outlined, taking into account the analysis of its effectiveness.

Organizational forms of analysing the effectiveness of tax planning at an enterprise may vary and are determined by its size, organizational and legal form, and industry specifics. Successful conduct of this analysis depends on carefully planned work. In addition, the information base of the analysis plays an important role, so before starting the analysis, it is necessary to check its completeness, quality and reliability. The article identifies the stages of assessing the effectiveness of tax planning of enterprises and proposes a system of performance indicators which can be used to carry out such an assessment.

A well-founded tax planning system can sufficiently minimize the risks arising from the taxation of business activities. And when making management decisions, tax planning is a mandatory tool for the company’s management. However, individual measures to optimize taxation will not become a full-fledged tax planning system unless they are implemented as part of a unified strategic plan for the development and operation of the company. Without fundamental provisions, methods and ways of developing (applying) certain tax optimization measures and schemes, tax planning cannot be implemented as intended, and will only act as a tool for minimizing tax payments in the short term – without planning the company’s activities and business development in the long term.
