GST Rules: Turnover Limits for Registration and Payment, Reverse Charge Mechanism, and E-Commerce Operator Liability Explained

GST is payable by registered taxable persons on the supply of goods and services, with CGST/SGST applicable to intra-State and IGST to inter-State supplies. Suppliers of goods are exempt from registration and GST payment if their turnover is below Rs. 40 Lakh, or Rs. 20 Lakh in specified states, while service suppliers have a Rs. 20 Lakh threshold. Taxpayers making inter-State supplies or under reverse charge must pay GST regardless of turnover. Under the reverse charge mechanism, the recipient pays the tax for certain supplies. For specific services via e-commerce platforms, the operator is liable to pay GST.
