The digital transformation of business and the public sector has had a significant impact on business activities. New types of business have emerged, mainly carried out in the digital space. In addition, new means of payment have emerged: cryptocurrencies and digital financial assets. These facts are shocks to tax administration models created to interact with taxpayers engaged in traditional activities. In this regard, in 2020, the Organization for Economic Co-operation and Development (OECD) at the XIII plenary meeting of the Forum on Tax Administration proposed the concept of digital transformation of tax administration “Tax Administration 3.0: Digital transformation of tax administration.” Taking into account the noted factors, the article provides a theoretical analysis of the risks caused by digital transformation for the purposes of tax administration, and also considers the best practices for leveling risks, including through the digitalization of tax administration. The subject of the study is the digital transformation of tax administration in the Russian Federation. The purpose of the study is to develop proposals for the development of tax administration in the Russian Federation, taking into account the best global practices, as well as using advanced technologies of the digital economy. As part of the study, the following research methods were used: retrospective analysis, synthesis, comparison and forecasting. The article provides a general analysis of the phenomenon of digital transformation and the associated risks for the purposes of tax administration; OECD proposals for the digital transformation of tax administration were reviewed, including their advantages and disadvantages; actual approaches to the transformation of the tax administration model used in the Russian Federation are noted. The scientific novelty of the work is expressed in the proposed further directions for the development of tax administration in the Russian Federation, including: the development of electronic document management; expanding the use of Blockchain technology; using the capabilities of smart contracts to automate the process of calculating and paying taxes. The solutions proposed in the study can be used in the practical implementation of measures to develop tax administration in the Russian Federation.
