Value-added taxation is a multidimensional theoretical, fiscal and legal structure. It also serves as a tool for the practical transformation of political, legal and socio-economic relations. The objective of the research is to study new concepts of value-added taxation formed in the two largest BRICS economies (the People’s Republic of China and the Republic of India). The assumption is that not only “European” model of the legal regulation of VAT can be successful, but alternatively “Chinese” and “Indian models.” The author examines and evaluates changes in the legal structure of value added tax in general, and its elements focusing on the current stage of legal regulation of national systems of VAT (GST) in China and India. In addition, the political, legal, social and economic effects of the legal mechanism of VAT (GST) in China and India from 2017 to 2020 are demonstrated.
