Charging the correct type of GST is important for every registered business. Whether an invoice should contain CGST and SGST, CGST and UTGST, or only IGST depends mainly on the supplier’s location and the place of supply.
Using the wrong tax type may create incorrect tax liability, return mismatches, input tax credit problems, and additional refund work. This is especially important for businesses selling across states, providing services remotely, operating through multiple GST registrations, or supplying through online platforms.

Assistance is available for GST registration, invoice review, return filing, input tax credit reconciliation, and compliance matters. Professional review can help identify classification and reporting errors before the GST returns are filed.
What Is GST?
The Goods and Services Tax is a destination-based indirect tax on the consumption of goods and services. Tax is collected at different stages of the supply chain, while eligible tax paid at previous stages may be available as Input Tax Credit.
Because GST is destination-based, the tax revenue generally belongs to the jurisdiction where the goods or services are consumed. The place of supply is therefore important for deciding whether a transaction is intra-state or inter-state.
GST brought several earlier central and state indirect taxes, such as service tax, central excise duty and State VAT, into a common tax framework. India follows a dual GST model in which the central government and the relevant state or union territory may collect tax on the same intra-state supply.
Four Types of GST at a Glance
GST Type | Full Form | Usually Applies To | Collected By |
CGST | Central Goods and Services Tax | Taxable intra-state supplies | Central Government |
SGST | State Goods and Services Tax | Taxable intra-state supplies within a state | State Government |
IGST | Integrated Goods and Services Tax | Inter-state supplies and imports | Central Government |
UTGST | Union Territory Goods and Services Tax | Local supplies in applicable Union Territories | Union Territory Administration |
What Is CGST?
CGST stands for Central Goods and Services Tax. It is the Central Government’s portion of GST on a taxable supply treated as intra-state.
CGST is normally charged together with SGST when the supplier’s location and place of supply are in the same state.
For example, suppose a registered seller in Madhya Pradesh supplies taxable goods to a customer in Madhya Pradesh. If the applicable total GST rate is 18%, the invoice will generally show:
- CGST: 9%
- Madhya Pradesh SGST: 9%
The customer pays a total tax of 18%, but the amount is divided between the Central Government and the state government.
CGST is not charged alone on a normal intra-state taxable transaction. It is accompanied by SGST or, where applicable, UTGST. The Central Government administers CGST and IGST, while the relevant state administers SGST.
What Is SGST?
SGST stands for State Goods and Services Tax. It is the state government’s portion of GST on a taxable supply within that state.
Suppose a business registered in Maharashtra supplies goods to a customer and the place of supply is also Maharashtra. The seller will generally charge Maharashtra SGST along with CGST.
The SGST collected on the transaction belongs to the relevant state government. Therefore, Madhya Pradesh SGST cannot be charged on a supply whose place of supply is Maharashtra.
Businesses with registrations in multiple states must treat each GST registration carefully. A branch registered in one state and another branch registered in a different state are generally treated as distinct persons under GST. Supplies between such registrations may attract IGST even where both registrations belong to the same legal entity.
What Is IGST?
IGST stands for Integrated Goods and Services Tax. It generally applies when a taxable supply is treated as inter-state.
For example, when a registered seller in Delhi supplies goods to a customer in Gujarat and the place of supply is Gujarat, IGST is generally charged.
If the applicable GST rate is 18%, the invoice will normally show:
- IGST: 18%
- CGST: Nil
- SGST: Nil
IGST is collected by the Central Government and later apportioned between the Centre and the destination state according to the applicable mechanism. This system helps maintain the Input Tax Credit chain when goods or services move across states.
IGST may apply to:
- Supplies from one state to another
- Inter-state branch transfers
- Supplies to or by an SEZ in applicable cases
- Imports of goods or services
- Certain transactions where the supplier and place of supply are in different states or Union Territories
The physical location of the customer is not always enough to decide the tax. Place-of-supply provisions must be checked, particularly for services, immovable property, transportation, events and transactions involving different billing and delivery locations.
What Is UTGST?
UTGST stands for Union Territory Goods and Services Tax. It applies along with CGST to taxable intra-territory supplies in Union Territories without their own legislature.
Applicable Union Territories include:
- Andaman and Nicobar Islands
- Chandigarh
- Dadra and Nagar Haveli and Daman and Diu
- Lakshadweep
- Ladakh
For example, if a taxable supply takes place within Chandigarh and the applicable total rate is 18%, the invoice will generally show 9% CGST and 9% UTGST.
Union Territories with a legislature follow their applicable state-type GST law rather than UTGST. UTGST is intended for Union Territories without a legislature.
How Do You Decide Which GST Type to Charge?
The basic test is:
- Identify the location of the supplier.
- Determine the correct place of supply.
- Compare the two locations.
Supplier Location and Place of Supply | GST Treatment |
Same state | CGST and SGST |
Different states | IGST |
Same applicable Union Territory | CGST and UTGST |
Import into India | IGST, subject to applicable customs treatment |
Export from India | Generally treated as a zero-rated supply |
A business should not decide GST only from the customer’s billing address. The actual place-of-supply rule applicable to the transaction must be considered.
How Do Imports, Exports, and SEZ Supplies Work?
Imports are generally treated as inter-state supplies and may attract IGST along with applicable customs duties.
Exports of goods or services and eligible supplies to SEZ developers or SEZ units are treated as zero-rated supplies. An eligible exporter may follow the prescribed route for supply under a Letter of Undertaking without payment of integrated tax or another permitted refund route, subject to current conditions.
“Zero-rated” does not mean that the transaction is outside GST. It means that the law provides special tax and input tax credit treatment for qualifying supplies.

How Does Input Tax Credit Work Between GST Types?
Eligible Input Tax Credit is maintained under separate tax heads. Its utilisation follows prescribed rules.
Broadly:
- IGST credit is first used against IGST liability.
- Remaining IGST credit may be used against CGST and SGST or UTGST liability in the permitted order.
- CGST credit is first used against CGST and may then be used against IGST.
- SGST or UTGST credit is first used against the corresponding SGST or UTGST and may then be used against IGST.
- CGST credit cannot be directly used against SGST or UTGST.
- SGST or UTGST credit cannot be directly used against CGST.
These rules make correct invoice classification important. Tax paid under the wrong head may create unnecessary cash-flow and compliance problems.
What Happens If the Wrong GST Type Is Charged?
Suppose a business pays CGST and SGST after treating a transaction as intra-state, but it is subsequently held to be inter-state. The correct IGST must be paid, and the incorrectly paid CGST and SGST may be claimed as a refund through the prescribed process.
Similarly, where IGST was paid but the transaction is subsequently held to be intra-state, the correct CGST and SGST or UTGST must be paid, and the IGST may be claimed as a refund.
The GST law provides relief from interest on the correct tax in specified cases where the transaction is subsequently held to fall under the other category. However, documentation and refund procedures must still be completed.
Common Mistakes Businesses Should Avoid
The most common GST-type mistakes include:
- Charging CGST and SGST on an inter-state supply
- Charging IGST only because the customer has an out-of-state address
- Ignoring the place-of-supply rules for services
- Using the wrong state code in an invoice
- Treating branch transfers as non-taxable without review
- Applying SGST instead of UTGST in an applicable Union Territory
- Reporting inter-state B2C supplies under the wrong state
- Using CGST credit directly against SGST
- Treating exports as ordinary exempt supplies
- Filing returns without matching invoices and tax ledgers
Businesses should review GSTINs, state codes, delivery locations and the nature of the supply before issuing the invoice.
Conclusion
Understanding the types of GST is necessary for preparing correct invoices, paying tax under the correct head and claiming eligible Input Tax Credit. The key is to identify the supplier’s location and apply the correct place-of-supply rule before deciding between CGST and SGST, CGST and UTGST, or IGST.
