Introduction
India’s Goods and Services Tax (GST) system simplified the country’s indirect taxation structure by replacing multiple central and state taxes with a unified tax framework. While GST has streamlined taxation, many business owners, startups, traders, and professionals still find it challenging to understand the difference between CGST, SGST, and IGST.
Knowing how these GST components work is essential for proper invoicing, tax compliance, input tax credit claims, and GST return filing.
At Filing Pool, we help businesses understand GST regulations, complete GST registrations, and maintain full compliance with India’s taxation laws.
Understanding the GST Structure in India
GST is a destination-based indirect tax levied on the supply of goods and services. The tax collected depends on whether a transaction occurs within the same state or between different states.
GST is divided into three major components:
✔ CGST (Central Goods and Services Tax)
✔ SGST (State Goods and Services Tax)
✔ IGST (Integrated Goods and Services Tax)
Each component serves a specific purpose in distributing tax revenue between the Central Government and State Governments.
What is CGST?
CGST stands for Central Goods and Services Tax.
It is the portion of GST collected by the Central Government on transactions that occur within the same state.
Whenever a sale takes place within a state, the GST charged is divided equally between CGST and SGST.
Example of CGST
Suppose a business in Maharashtra sells goods worth ₹10,000 to another customer in Maharashtra and GST applicable is 18%.
GST Amount = ₹1,800
This will be divided into:
- CGST = 9% = ₹900
- SGST = 9% = ₹900
The CGST portion is deposited with the Central Government.
What is SGST?
SGST stands for State Goods and Services Tax.
It is the GST component collected by the respective State Government when a transaction occurs within the same state.
Whenever an intra-state supply takes place, SGST is charged alongside CGST.
Example of SGST
Using the previous example:
Product Value = ₹10,000
GST Rate = 18%
- CGST = ₹900
- SGST = ₹900
The SGST amount is received by the Maharashtra State Government.
What is IGST?
IGST stands for Integrated Goods and Services Tax.
It is applied when goods or services are supplied from one state to another state.
Instead of charging CGST and SGST separately, a single IGST is charged.
The Central Government collects IGST and later distributes the appropriate share to the destination state.
Example of IGST
A business in Maharashtra sells products worth ₹10,000 to a customer in Gujarat.
GST Rate = 18%
IGST Charged = ₹1,800
The seller collects ₹1,800 as IGST and deposits it with the Central Government.
Difference Between CGST, SGST, and IGST
| Particulars | CGST | SGST | IGST |
| Full Form | Central Goods and Services Tax | State Goods and Services Tax | Integrated Goods and Services Tax |
| Collected By | Central Government | State Government | Central Government |
| Applicable On | Intra-state transactions | Intra-state transactions | Inter-state transactions |
| Tax Sharing | Central Government | State Government | Shared between Centre & Destination State |
| Example | Mumbai to Pune | Mumbai to Pune | Mumbai to Ahmedabad |
| GST Split | Part of GST | Part of GST | Full GST collected as one tax |
When is CGST and SGST Charged?
CGST and SGST are applicable when:
- Buyer and seller are located in the same state
- Goods are delivered within the same state
- Services are provided within the same state
Example
Seller: Mumbai, Maharashtra
Buyer: Nagpur, Maharashtra
Applicable Tax:
- CGST + SGST
Since both parties are in Maharashtra, the transaction is intra-state.
When is IGST Charged?
IGST is applicable when:
- Buyer and seller are in different states
- Goods move from one state to another
- Cross-border transactions occur
- Imports and exports fall under GST provisions
Example
Seller: Maharashtra
Buyer: Karnataka
Applicable Tax:
- IGST
Since the transaction crosses state boundaries, IGST is charged.
How Input Tax Credit Works Under CGST, SGST, and IGST
One of the biggest advantages of GST is the Input Tax Credit (ITC) mechanism.
Businesses can claim credit for GST paid on purchases and use it to offset GST liabilities.
ITC Utilization Order
CGST Credit Can Be Used For:
- CGST liability
- IGST liability
SGST Credit Can Be Used For:
- SGST liability
- IGST liability
IGST Credit Can Be Used For:
- IGST liability
- CGST liability
- SGST liability
Proper ITC utilization helps reduce tax burdens and improves cash flow management.
