Introduction
The Goods and Services Tax (GST) is one of India’s most significant tax reforms. It replaced multiple indirect taxes such as VAT, Excise Duty and Service Tax to create a unified system under the concept of “One Nation, One Tax.” However, many businesses and taxpayers often get confused about the different types of GST—CGST, SGST and IGST. In this blog, we explain these three types of GST in a simple, clear, and practical manner.
What is GST in India?
GST (Goods and Services Tax), introduced on 1 July 2017, is a destination-based tax. This means tax is collected where goods or services are consumed, not where they are produced. GST applies to the supply of almost all goods and services across India.
Types of GST in India
GST in India is divided into three parts to ensure smooth revenue sharing between the Centre and States:
- CGST – Central Goods and Services Tax
- SGST – State Goods and Services Tax
- IGST – Integrated Goods and Services Tax
Each applies in different situations, explained below.
1️. CGST – Central Goods and Services Tax
CGST is levied by the Central Government on intra-state transactions—that is, when goods or services are supplied within the same state.
Example:
A trader in Maharashtra sells goods worth ₹1,00,000 to a customer in Maharashtra:
- CGST: 9% = ₹9,000
- SGST: 9% = ₹9,000
- Total GST 18% = ₹18,000
The CGST portion goes to the Central Government.
Key Points:
- Applicable within the same state
- Collected by the Central Government
- ITC can be used to pay CGST and IGST
2️. SGST – State Goods and Services Tax
SGST is levied by the State Government on intra-state supplies.
In the Maharashtra example above, the SGST portion (₹9,000) goes to the State Government.
Key Points:
- Applicable within the same state
- Collected by respective State Government
- ITC can be used to pay SGST or IGST
3️. IGST – Integrated Goods and Services Tax
IGST is levied by the Central Government on inter-state supplies—when goods or services move from one state to another.
Example:
If a trader in Maharashtra sells goods to a customer in Gujarat, IGST applies.
- IGST Rate: 18% (same as CGST+SGST combined)
- The tax collected is shared between Centre and State.
Key Points:
- Applicable on inter-state transactions.
- Collected by the Central Government.
- Ensures smooth flow of credit between states.
Difference between CGST, SGST, and IGST
| Basis | CGST | SGST | IGST |
| Full Form | Central Goods and Services Tax | State Goods and Services Tax | Integrated Goods and Services Tax |
| Levied By | Central Government | State Government | Central Government |
| Type of Transaction | Intra-State | Intra-State | Inter-State |
| Revenue Sharing | Central Govt | State Govt | Shared between Centre & State |
| Input Tax Credit (ITC) | Can be used for CGST & IGST | Can be used for SGST & IGST | Can be used for IGST, CGST, SGST |
| Example | Sale within Maharashtra | Sale within Maharashtra | Sale from Maharashtra to Gujarat |
Example to Understand GST Types
Let’s take a simple example:
Scenario 1: Intra-State Sale (within Maharashtra)
- Product Value: ₹1,00,000
- CGST: 9% = ₹9,000
- SGST: 9% = ₹9,000
- Total GST Payable: ₹18,000
Scenario 2: Inter-State Sale (Maharashtra to Gujarat)
- Product Value: ₹1,00,000
- IGST: 18% = ₹18,000
- Total GST Payable: ₹18,000
In both cases, the total tax is the same, but how it’s distributed differs.
Why GST is divided into Three Parts
GST collection is shared fairly between the Centre and the States. Before GST, the tax structure was messy and overlapping.
The three-part GST system ensures:
- Proper division of revenue
- Better compliance
- Smooth movement of goods across India
- Avoidance of double taxation
FAQs on Types of GST
1. Why are there different types of GST?
Because both the Central and State Governments collect tax, GST is divided into CGST, SGST, and IGST to balance the revenue.
2. Who collects IGST?
IGST is collected by the Central Government and later distributed between the Centre and the State where the goods are consumed.
3. Can a business claim ITC for all three GST types?
Yes, businesses can claim Input Tax Credit for CGST, SGST, and IGST as per GST rules.
4. Is the GST rate same for all products?
No, GST rates vary from 0% to 28% depending on the category of goods or services.
5. How do I know which GST applies to my business?
If your transaction is within the same state, CGST & SGST apply. If it’s between different states, IGST applies.
