GST is an Indirect Tax which is levied on the supply of both goods and services in India. It is destination-based tax where tax is levied on every value addition. It was implemented on 1st July 2017. All the state and central taxes and duties under the erstwhile indirect tax regime except Custom Duty levied on import of goods were subsumed with the implementation of GST.
India has adopted a dual GST model where GST shall have two components one levied by the Centre (referred to as Central GST), and the other levied by the States (referred to as State GST).
