Under the GST regime, tax is payable by the taxable person on the supply of goods and/or services. Liability to pay tax arises when the taxable person crosses the threshold exemption, i.e. Rs.10 lakhs (Rs. 5 lakhs for NE States) except in certain specified cases where the taxable person is liable to pay GST even though he has not crossed the threshold limit. The CGST / SGST is payable on all intra-State supply of goods and/or services and IGST is payable on all inter-State supply of goods and/or services. The CGST /SGST and IGST are payable at the rates specified in the Schedules to the respective Acts.
