Active development of digitalization processes worldwide is changing the usual mode of the operation of all areas of human activity. These processes have a special impact on the development of economic systems. The introduction of new information technologies in economic relations today is the norm and objectively necessary to ensure the competitiveness of national economies. Up to date, the outlined technologies play an essential role in reforming tax systems, which determines the relevance of this sphere of research considering the potential of digitalization and its application in this area. The purpose of the article is to conduct a bibliographic analysis of the state of research papers in the digitalization of tax systems and establish current trends in the scientific development of this system. The systematization of scientific sources and approaches to solving the taxation digitalization problem showed the lack of scientific papers in this area. Accordingly, the urgency of solving this situation is to conduct new research in this area to deepen the understanding of current trends in introducing new innovative technologies from the theoretical, methodological, and practical points of view. The methodical toolkit of the study was the methods of bibliographic and comparative analysis. As the information base to conduct research, the Scopus database was used. The empirical study was conducted using a bibliometric approach known as «the common words analysis» using the VOSviewer software. The analysis of the relevance of the study of taxes and digitalization as a separate scientific category was conducted. It was determined that for the last five years, there had been a significant growth of scientific research in digitalization as an objective process of reality, the analysis of which is studied within various sciences. The categorial relationship between keywords found in scientific papers, where the words «taxes» and «digitalization» are met, is analysed within the article. It made it possible to identify the following areas of research, within which the issues of digitalization of the tax system were studied individually: works related to the study of peculiarities of the international trade development, taxation in online trade; research papers, within which the taxation issues of business entities that do not have a physical location in the countries where they operate are studied; articles, which study the issues of enterprise management, the development of enterprise management in the digital age; papers, which analyse `the issues of reforming tax systems, the introduction of innovations to improve their functioning.
