<h1>Goods and Service Tax: a destination based dual GST with IGST settlement, Council governance, ITC rules and transitional compensation.</h1> Implementation of a destination based Goods and Services Tax (GST) established concurrent taxing powers through constitutional amendment, created a dual GST model (CGST/SGST) with an IGST mechanism to preserve input tax credit across inter State supplies, and formed the Goods and Services Tax Council to recommend rates, exemptions, place of supply principles and transitional compensation. The statutory framework (CGST, SGST/UTGST, IGST and Compensation Acts) sets multi rate slabs, threshold and composition schemes, zero rating for exports, ITC cross utilisation rules, procedural measures for registration, returns, refunds and settlements, and institutional/IT arrangements through CBIC and GSTN to operationalise the regime.
