Types of GST

1. IGST (Integrated Goods and Services Tax)
IGST is a tax slab applicable in transactions between two states, i.e., interstate transactions. It is usually levied on goods or services transported from one state to another, and on a country’s import and export transactions. It is regulated as per the provisions and sections of IGST act by the Central Government. It states that the Centre has the authority to levy tax on all inter-state transactions.
2. SGST (State Goods and Services Tax)
SGST is a tax levied on transactions within the state i.e, intrastate transactions. It is levied by the State Government and governed by the SGST Act. The revenue generated by the SGST is utilised by the State Government only to carry out its functions.
3. CGST (Central Goods and Services Tax)
CGST is the tax levied by the Central Government on the movement, consumption, or transaction of goods and services. Governed by the CGST Act, it is a major source of income for the Central Government. The tax slabs of CGST are similar to SGST.
4. UTGST (Union Territory Goods and Services Tax)
As the name suggests, UTGST is a tax levied on the union territories of India, namely Andaman and Nicobar Islands, Chandigarh, Ladakh, Lakshadweep, Puducherry, Daman and Diu, Delhi, Jammu and Kashmir, and Dadra and Nagar Haveli. Union Territory Government levies and regulates this tax according to the provisions specified in the UTSGT Act. This Act replaces the SGST in UTs and is charged along with CGST in the specified areas.
Why There are Different Types of GST?
The Indian Constitution divides the administrative powers between the Centre and the State. It provides that both the State Government and Central Government will work in their respective spheres and neither shall, in any case, encroach upon the power of the other. Both governments have different responsibilities and functions.
To ensure harmony and peace in the functioning of both governments, the GST is divided into different types to allow each government to levy and collect its own tax for smooth functioning.
