IGST, CGST & SGST: Understanding the Difference at a Glance

GST is an important part of India’s indirect tax system, but understanding the difference between IGST, CGST and SGST can sometimes be confusing for business owners, accountants and taxpayers.

The key to understanding these taxes is simple: look at whether the supply is inter-State or intra-State.

🔹 What is IGST?

IGST – Integrated Goods and Services Tax applies mainly to inter-State supplies, where the supplier and the place of supply are in different States or Union Territories.

For example:

Delhi Seller → Maharashtra Buyer = IGST

IGST is levied and collected by the Central Government, with the tax revenue subsequently apportioned according to the GST settlement mechanism.

🔹 What is CGST?

CGST – Central Goods and Services Tax applies to the Central Government’s share of an intra-State supply.

For example:

Delhi Seller → Delhi Buyer = CGST + SGST

The CGST portion goes to the Central Government.

🔹 What is SGST?

SGST – State Goods and Services Tax is the State Government’s component of an intra-State supply.

So, when a taxable supply takes place within the same State, CGST and SGST are generally charged together.

A simple way to remember:

Inter-State → IGST

Intra-State → CGST + SGST

The GST Portal also determines whether a transaction is inter-State or intra-State based on the supplier’s State and the applicable place of supply.

💡 Why does this distinction matter?

Correctly identifying the nature of supply and place of supply is essential for:

✅ Correct tax calculation ✅ Accurate invoicing ✅ Proper Input Tax Credit (ITC) utilisation ✅ GST return reporting ✅ Avoiding tax mismatches and compliance issues

For taxable supplies, the GST e-invoice system generally requires either IGST or CGST + SGST/UTGST, depending on the nature of the transaction.

Final Takeaway

Understanding GST becomes much easier when you start with one question:

“Is the supply inter-State or intra-State?”

➡️ Inter-State = IGST ➡️ Intra-State = CGST + SGST

A small difference in classification can have a significant impact on invoicing, tax payment and compliance.
