In GST (Goods and Services Tax), an intra-state supply is defined as a transaction where the supplier and the place of supply, i.e., that of the recipient, are located in the same state/union territory. These transactions are subject to both Central GST (CGST) and State GST (SGST), which is usually shared equally between the central and state governments.
Proper identification of a transaction as intra-state directly determines the difference in the tax charged on invoices and reported in GST returns.
Key elements used to determine intra-state supply
A transaction is classified as intra-state by comparing two key factors: the location of the supplier and the place of supply. Both must be in the same state for the transaction to qualify as intra-state.
Location of supplier
The location of the supplier refers to the registered place of business where the supply is made. This is usually the principal place of business as stated in the GST registration. This identifies the origin point of the transaction.
Place of supply
The place of supply is where the goods are delivered or where the service is actually used. It is determined based on the GST place-of-supply regulations.
If they are located in the same state, the supply is intra-state. If they are in different states, the supply is interstate.
Tax rules for intra-state supply
Tax on intra-state supply is determined by how GST is applied by splitting the total tax between the central and state governments.
Taxes applicable
Intra-state transactions are subject to two types of GST:
- Central Goods and Services Tax (CGST), which is collected by the central government.
- State Goods and Services Tax (SGST), which is collected by the state government.
Both taxes are levied simultaneously on a transaction value.
How tax is applied
In intra-state transactions, the total GST rate is divided equally between CGST and SGST.
For example, an 18% GST rate is split into 9% CGST and 9% SGST. The amount of the tax paid by the purchaser is the same, but is shared by two authorities. This division ensures that the central and state governments get their portion of tax revenue.
What does not apply
IGST (Integrated Goods and Services Tax) is for inter-state transactions, and does not apply to intra-state supplies. IGST is only applied when services or goods are supplied across states.
Charging IGST instead of CGST and SGST charges can result in incorrect tax reporting and compliance problems.
Examples of intra-state supply in GST
Example for goods
For instance, say a supplier in Karnataka sells goods worth ₹1,00,000t to a buyer who is also located in Karnataka, then such a supply will be considered an intra-state supply. As a result, GST is applied in the form of CGST and SGST instead of IGST.
If the applicable GST rate on the goods is 18%, the total tax of ₹18,000 is split equally between the central and state governments, with ₹9,000 charged as CGST and ₹9,000 as SGST.
Example for services
An intra-state supply also applies to services. For instance, a consultant in Delhi provides services for ₹50,000 to a client in Delhi. Since both the supplier and the place of supply are in Delhi, the transaction qualifies as an intra-state supply.
Accordingly, GST is applied as CGST and SGST. If the service attracts an 18% GST rate, the total tax of ₹9,000 is split into ₹4,500 CGST and ₹4,500 SGST.
What changes in the billing
This category directly affects the way the tax is shown on the invoice.
- CGST and SGST are levied on the same transaction value.
- The GST rate is the same, which is split equally between the two taxes.
- Both transactions should be shown separately to ensure proper compliance.
How to identify the intra-state supply of GSTIN
An effective method of determining intra-state supply is through the GSTIN structure.
- Identify the state code from the first two digits of the GSTIN
- Compare the supplier’s GSTIN with the place of supply.
- When both are the same state code, the transaction is intra-state.
It is a commonly used method in invoicing that also helps to minimize errors in classification.
Exceptions where supply is not treated as intra-state
Even if a transaction appears to be in one state, some cases are treated differently under GST.
- The supplies to or by Special Economic Zone (SEZ) units are considered inter-state.
- Goods imported before the clearance by customs are not considered intra-state.
- Certain transactions notified under the GST law are categorized as inter-state.
These exceptions must be handled carefully, as misclassification may cause tax mismatches and compliance problems.
Conclusion
Correct classification of intra-state supply is essential for applying the right taxes and ensuring accurate GST reporting and reconciliation. It also ensures that CGST and SGST are applied correctly instead of IGST, preventing errors in tax filing and credit utilisation.
For businesses handling frequent transactions, it is much easier to manage when your system can automatically identify locations, split tax correctly, and maintain compliance, which tools like TallyPrime help achieve efficiently.
