In this paper, an attempt has been made to analyse the implications of tax reforms after the economic liberalization in
1991 with respect to collection of indirect tax revenue of the Government of India during the last two decades (2000-20). The
composition of indirect tax revenue of the Government has undergone a drastic change during the last two decades. Post
implementation of the GST Act, the levy of Central Excise has been restricted to petroleum and tobacco products and GST has
evolved as the major contributor to the indirect tax revenue collections followed by the Customs Duty.
