A Closer Look at GST

The Goods and Services Tax (GST) was introduced to create uniformity in tax collection across the country. Under the GST framework, tax is applied cumulatively at the final stage of goods or service production. GST is structured into five tax slabs: 0%, 5%, 12%, 18%, and 28%, with different products and services assigned to specific slabs. Additionally, some items are exempt from GST altogether—learn more about them here.

Types of GST in India

India’s GST system comprises four main categories, each serving a distinct purpose:

CGST (Central Goods and Services Tax)

• • • What It Is: CGST is imposed by the central government for the supply of goods and services within a state (intra-state).
    • Key Features: Governed by the CGST Act, this tax is applied alongside SGST, with both generally having equal rates.

SGST (State Goods and Services Tax)

• • • What It Is: SGST is levied by state governments on intra-state transactions.
    • Key Features: It operates in tandem with CGST, and the rates for both are typically the same. The SGST Act governs its implementation.

IGST (Integrated Goods and Services Tax)

• • • What It Is: IGST is collected by the central government on inter-state supplies and imports of goods and services.
    • Key Features: Once collected, the central government distributes the IGST revenue to the respective states based on the transaction’s origin and destination.

UTGST (Union Territory Goods and Services Tax)

• • • What It Is: Applicable to the supply of goods or services in India’s seven Union Territories.
    • Key Features: UTGST is charged alongside CGST and follows similar rules for implementation.
