GST Flow System

Decode India's Indirect Tax regime. Understand how CGST, SGST, and IGST work together in a unified market, and how Input Tax Credit (ITC) prevents cascading effects.

The GST Ecosystem

Goods and Services Tax (GST) is a comprehensive, multi-stage, destination-based tax that is levied on every value addition. It replaced almost all indirect taxes in India, creating a 'One Nation, One Tax' system.

CGST

Central GST

Collected by the Central Govt on intra-state sales.

SGST

State GST

Collected by State Govts on intra-state sales.

IGST

Integrated GST

Collected by Central Govt on inter-state sales.

The Magic of Input Tax Credit (ITC)

Input Tax Credit is the backbone of GST. It allows a business to reduce the tax it has already paid on inputs from the tax it has to pay on output. This removes the Cascading Effect (Tax on Tax).

Without GST
Tax is calculated on the total value at every stage, including the tax paid in previous stages. Final price is much higher.
With GST (ITC)
Tax is only calculated on the value added at that stage. Tax paid on inputs is credited back. Final price is lower.

UPSC Key Concept: GST Council

Constitutional Body (Article 279A)

Headed by the Union Finance Minister, it includes representatives from all states. It is the apex body that decides tax rates, exemptions, and thresholds. Decisions are taken by a 3/4th majority, ensuring cooperative federalism.
