What is GST?
GST (Goods and Services Tax) is an indirect tax levied on the supply of goods and services in India. It is a destination-based tax, meaning the tax is collected by the state where goods or services are consumed, not where they are produced.
GST is charged at every stage of the supply chain, but the final tax burden is borne by the end consumer because of the Input Tax Credit (ITC) mechanism.
In simple words:
GST is a single tax that replaces multiple indirect taxes and is charged on value addition at each stage.
Why was GST Introduced?
GST was introduced to solve many problems in the old tax system.
Problems Before GST
- Multiple taxes by center and states
- Tax on tax (cascading effect)
- Different tax rates in different states
- Complicated compliance
- Difficulty in interstate trade
Objectives of GST
- One Nation, One Tax
- Remove cascading effect of taxes
- Increase transparency
- Boost economic growth
- Improve ease of doing business
How Does GST Work?
GST works on the concept of Input Tax Credit (ITC).
Example:
- Manufacturer buys raw material for ₹100 and pays ₹18 GST
- Manufacturer sells product for ₹200 and charges ₹36 GST
- GST payable = ₹36 – ₹18 (ITC) = ₹18
So, tax is paid only on value added, not on the entire amount.
Types of GST in India

1. CGST (Central Goods and Services Tax)
