Authority of the Central and State Governments Over GST

Before the introduction of GST, both central and state governments used to collect a variety of taxes from businesses including VAT (Value Added Tax), CST (Central Sales Tax), excise duty, and service tax. GST simplified the taxation system of the country as most other indirect taxes were replaced by the GST.

Since both central and state governments need to collect taxes, the GST law, as explained above, has the provision for four types of GSTs which are applicable in different situations and are collected by either a state government or the central government.

The following table illustrates the taxes collected by the central and the state governments before and after the introduction of the GST system:

Collecting Authority	Erstwhile Taxes	Taxes Collected As Per the GST Law
State Government	Value Added Tax (VAT) & Excise / Service Tax	SGST- levied on intra-state supply of goods and services
Central Government	Central Sales Tax (CST) & Excise / Service Tax	CGST- levied on intra-state supply of goods and services and IGST- levied on inter-state supply of goods and services.

How are SGST, CGST and IGST Collected

SGST (State Goods and Services Tax), as is obvious from the name, is collected by the state governments while CGST (Central Goods and Services Tax) and IGST (Integrated Goods and Services Tax) are collected by the central government. Which of these taxes would be applicable depends upon whether the supply of the goods/services is within a state or from one state to another.

SGST: State Goods and Services Tax (SGST) is collected by the state government on intra-state supply of goods and services (supply of goods/services within a state).
CGST: Central Goods and Services Tax (CGST) is collected by the central government over and above the SGST on intra-state supply of goods and services.

IGST: Integrated Goods and Services Tax (IGST) is also collected by the central government on the inter-state supply of goods and services (supply of goods/services from one state to another). The IGST revenue is equally divided between the central and the state government (state government of the state where the goods/services are consumed).

Let us now understand how CGST, SGST and IGST are collected with the help of two examples. Suppose a product is being supplied from Mumbai to Pune (within Maharashtra). Both the central government and the Maharashtra government will levy CGST and SGST respectively as it is an intra-state supply of goods. However, if a product is being transported from Mumbai (in Maharashtra) to Ahmedabad (in Gujarat), only the central government will collect the IGST and the revenue will be shared equally between the centre and the government of Gujarat.

Can CGST and SGST be Charged Together

If goods/services are being supplied from one place to another within the same state (intra-state supply), both CGST and SGST are levied together by the central and the state government respectively. The amounts collected as SGST and CGST are equal as both central and state governments have an equal revenue sharing arrangement as per the GST law.

The GST has sought to make the taxation system simpler for the Indian traders, but it is essential to understand the difference between CGST, IGST and SGST. GST is applicable on all businesses with a turnover of more than Rs. 20 Lakhs.
