Who is liable to pay GST under the proposed GST regime?

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 interState
supply of goods and/or services. The CGST /SGST and
IGST are payable at the rates specified in the Schedules to
the respective Acts.
