Authority of the State/Centre over these taxes which defines these taxes

A federal country such as India, where both the Centre and the States have been assigned the powers to levy and collect taxes. Both centre and state government have distinct responsibilities to perform, as per the Constitution, for which they need to raise resources.

The GST to be levied by the Centre on intra state supply of goods and / or services is Central GST (CGST) and that by the States is State GST (SGST). On supply of goods and services outside the state, Integrated GST (IGST) will be collected by Centre. IGST also applies on imports as well.

Sale within the state

Value Added Tax (VAT) & Excise /  Service Tax


Under GST, a transaction of sale within the state shall have two taxes, SGST which share is taken by the state and Central GST which goes to the centre.

Sale outside the state

Central Sales Tax (CST) & Excise / Service Tax


A transaction of sale outside the state shall have only one type of tax, IGST which goes to the centre.

Consumption determines the type of levy – CGST/ SGST and IGST

GST is a consumption based tax i.e. proceeds of taxes should be received by the state in which the goods or services are consumed and not by the state in which such goods are manufactured. Integrated GST is designed to ensure seamless flow of input tax credit from one state to another.

One state has to deal only with the Centre government to settle the tax amounts and not with every other state, thus making the process easier.
