Historic! one nation, one tax GST

India is a federal country where both the Centre and the States have been assigned the powers to levy and collect taxes through appropriate legislation. India has chosen the Canadian model of dual GST. A dual GST will, therefore, be in keeping with the Constitutional requirement of fiscal federalism. The Central GST and the State GST would be levied simultaneously on every transaction of supply of goods and services except the exempted goods and services, goods which are outside the purview of GST and the transactions which are below the prescribed threshold limits.
