In India’s GST landscape, understanding the distinction between interstate and intrastate supplies is particularly crucial for the millions of MSMEs that form the backbone of the nation’s economy.
For small and medium enterprises operating across multiple states or planning to expand beyond their local markets, this classification impacts everything from tax rates and compliance procedures to fundamental business decisions. As more MSMEs embrace digital transformation and explore opportunities beyond their state boundaries, mastering the nuances of interstate and intrastate GST supplies becomes more than just a compliance requirement—it’s a strategic necessity.
Whether you’re a local manufacturer in Gujarat selling to retailers in Maharashtra, or a small service provider in Karnataka catering to clients across India, understanding these distinctions affects your pricing strategies, working capital management, and ultimately, your business growth. For MSMEs already juggling multiple operational challenges, getting this aspect right can mean the difference between smooth tax compliance and costly regulatory hurdles.
What is Interstate Supply?
Interstate supply refers to transactions where the seller and the place of supply are in different states or Union Territories. These transactions attract Integrated GST (IGST), which is collected by the central government.
For MSMEs operating across state borders, IGST simplifies taxation by ensuring a single levy instead of multiple state taxes. The collected tax is later distributed between the central and state governments, reducing compliance burdens and ensuring fair revenue sharing. Understanding IGST helps businesses manage tax obligations smoothly while expanding beyond their home state.

What is Intrastate Supply?
Intrastate supply occurs when both the supplier and the place of supply are located within the same state. Such transactions are subject to Central Goods and Services Tax (CGST) and State Goods and Services Tax (SGST) or Union Territory Goods and Services Tax (UTGST). These taxes are imposed separately by the central and state/UT governments.
The applicable GST rate for intrastate transactions varies based on the nature of goods or services provided. In such cases, businesses must collect both CGST and SGST from customers during the transaction.
Comparing Interstate and Intrastate GST Supply

FAQs
1. How is GST charged on interstate supplies?
GST on interstate supplies is charged as Integrated GST (IGST). The supplier collects IGST from the buyer and remits it to the central government. The destination state then receives its share as per GST distribution rules.
2. How is GST charged on intrastate supplies?
GST on intrastate supplies is charged as Central GST (CGST) and State GST (SGST) in equal proportions. The supplier collects both taxes from the buyer and remits CGST to the central government and SGST to the respective state government.
3. Can an intrastate transaction ever attract IGST?
Yes, an intrastate transaction can attract IGST in specific cases, such as supplies to Special Economic Zones (SEZs) or when a registered dealer purchases from an unregistered supplier under the reverse charge mechanism (RCM).
4. How do GST rates differ for interstate and intrastate supplies?
GST rates remain the same for interstate and intrastate supplies. However, interstate supplies attract Integrated GST (IGST), while intrastate supplies are subject to Central GST (CGST) and State GST (SGST), each charged at half the IGST rate.
5. Do small businesses under the composition scheme pay IGST?
No, businesses under the GST composition scheme cannot make interstate supplies and thus do not pay IGST. They only pay a fixed percentage of turnover as CGST and SGST on intrastate sales and cannot claim input tax credit.
