What is GST?
The Goods and Services Tax (GST) is India’s indirect tax on the supply of goods and services. Introduced on 1 July 2017, GST replaced multiple indirect taxes such as VAT, Service Tax, Excise Duty, and Entry Tax.
It has streamlined India’s tax structure into “One Nation, One Tax”, ensuring transparency and uniformity across states.

Types of GST in India
| Type | Description | Levied By |
|---|---|---|
 CGST (Central GST) | Collected on intra-state supplies | CGST (Central GST) |
 SGST (State GST) | Collected on intra-state supplies | State Government |
 IGST (Integrated GST) | Applied to inter-state supplies & imports | Central Government |
 UTGST (Union Territory GST) | Applied in Union Territories | Union Territory Administration |
1. Central Goods and Services Tax (CGST)
CGST is imposed by the Central Government on the intra-state supply of goods and services. It is collected along with SGST, and both taxes are charged at equal rates on the same transaction value.
2. State Goods and Services Tax (SGST)
SGST is levied by the State Government on intra-state sales of goods and services. The revenue collected through SGST directly benefits the respective state, ensuring local development and fair distribution of tax proceeds.
3. Integrated Goods and Services Tax (IGST)
IGST is applied on inter-state transactions of goods and services, including imports into India. The Central Government collects IGST and later distributes the revenue between the Centre and destination states to avoid double taxation.
4. Union Territory Goods and Services Tax (UTGST)
UTGST is applicable to the intra-territory supply of goods and services within India’s Union Territories, such as Delhi, Chandigarh, and Puducherry. It functions like SGST but is governed by the Union Territory administration instead of a state government.
