Under India's Goods and Services Tax (GST) framework, supplies are classified as either interstate or intrastate, and the type of supply determines the type of GST tax that applies. Interstate supply happens when the location of supply is in a different state or union territory than the supplier, resulting in IGST.
Intrastate supply occurs when the supplier and the location of supply are in the same state/union territory, in which case CGST and SGST are taxed in equal amounts. Accurate classification ensures that taxes are levied correctly, compliance is met, and input tax credits are used effectively.
Key Takeaways
-
IGST is imposed on interstate supplies under GST legislation.
-
On intrastate supplies, both CGST and SGST/UTGST are charged equally.
-
GST is a destination-based tax, with place of supply laws determining the tax type.
-
Supplies to or from SEZ units or developers are treated as interstate supplies even if technically within the same state

What is the Meaning of Interstate in GST?
In the Goods and Services Tax system, an interstate transaction is one where the supplier of goods and services is in one state (or union territory), and the place of supply is in another state (or union territory) as defined under Section 7 of the IGST Act, 2017.
For example: Assume there is a furniture manufacturer based in Maharashtra that sells a consignment of chairs to a retailer based in Gujarat. Since the supplier of the goods resides in Maharashtra and the place of supply of the said goods takes place in Gujarat, this transaction is classified as an interstate supply under GST.
What is the Meaning of Intrastate in GST?
An intrastate transaction is one where the supplier of goods and services and the place of supply are both within the same state or union territory as defined under Section 8 of the IGST Act, 2017.
For example: Assume that the Maharashtra-based furniture manufacturer referred to in the previous example sells a consignment of tables to a retailer based in the same state. Since the supplier of the goods resides in Maharashtra and the place of supply of the said goods also takes place in Maharashtra, this transaction is classified as an intrastate supply under GST.
Interstate and Intrastate GST Rate With Examples
Under GST, the tax rate on goods and services stays the same, but the kind of tax imposed varies depending on whether the supply is interstate or intrastate. This categorisation is decided by the GST Act's place of supply requirements.
For interstate supplies, the entire GST rate is applied as IGST. For intrastate supplies, the same GST rate is split equally between CGST and SGST/UTGST.
Interstate GST Rate Example
Let’s assume there’s a dealer in Karnataka and they sell standard goods to a buyer in Maharashtra for ₹1,00,000, and the item attracts 18% GST.
This is an interstate supply, so IGST applied is 18%.
IGST = 18% of ₹1,00,000 = ₹18,000.
The invoice value becomes ₹1,18,000, and the supplier pays ₹18,000 IGST to the Centre, which is later apportioned to the destination state (Maharashtra).
Intrastate GST Rate Example
Now assume the same dealer in Karnataka sells the same goods for ₹1,00,000 to a buyer within Karnataka, with the same 18% GST rate.
This is an intrastate supply, so GST is split as 9% CGST + 9% SGST.
CGST = 9% of ₹1,00,000 = ₹9,000; SGST = 9% of ₹1,00,000 = ₹9,000.
The invoice value is still ₹1,18,000, but ₹9,000 goes to the Central Government (CGST) and ₹9,000 to the state government (SGST).

Difference Between Interstate and Intrastate
Here is a detailed tabulated comparison of interstate vs. intrastate transactions in the Goods and Services Taxation system. The table below should help you better understand the various distinctions between these two concepts.

Particulars |
Interstate Supply |
Intrastate Supply |
|
Definition |
Movement of goods or services between different states or union territories. |
Movement of goods or services within the same state or union territory. |
|
Applicable Taxes |

Central Goods and Services Tax (CGST) + State Goods and Services Tax (SGST). |

Tax Rates |
Full slab as IGST (e.g., 18%). |
Split equally (e.g., 9% + 9% for 18% slab). |
|
Revenue to the State Receiving the Supply |
The state that receives the supply of goods or services is provided with a share of the tax revenue collected as IGST. |
The state receives the full amount of the tax revenue collected as SGST. |
|
Use of Input Tax Credit |
IGST credit is first used to set off IGST liability, then CGST liability, and then SGST liability, in that order. |
|
With this, the comparison of interstate vs. intrastate in GST is now complete. The primary differences between the two lie in the place of supply, applicable taxes, and input tax credit utilisation.
Conclusion
The classification of interstate and intrastate supply is governed by Sections 7 and 8 of the IGST Act, 2017, and is determined based on the place of supply rules prescribed under Sections 10, 12, and 13 of the Act. Both interstate and intrastate supply of goods and services are crucial concepts in the Goods and Services Taxation system.
Businesses must carefully determine the nature of their transactions to ensure proper tax calculation, input tax credit utilisation, and compliance with the various regulations.
Furthermore, the GST system is ever-evolving, with new regulations and updates to the act being notified from time to time. To thrive in the Indian market, business owners must stay informed about the various changes to the regulations.
