Understanding whether your GST is central (CGST) or state (SGST) is important for compliance and smooth business operations. In this blog, we’ll simplify everything you need to know about how GST works, how to read your GSTIN, and how to identify the nature of your GST – whether it is central or state.
What is GST and What Does It Include?
The Goods and Services Tax (GST) is a unified tax system in India that replaces multiple indirect taxes. It includes:
- CGST (Central GST) – Collected by the Central Government.
- SGST (State GST) – Collected by the State Government.
- IGST (Integrated GST) – Applicable for inter-state transactions.
Every registered GST taxpayer is issued a 15-digit unique GSTIN (Goods and Services Tax Identification Number), which contains all the information about their registration, including state and central code identification.
Understanding Your 15-Digit GSTIN
To identify whether your GST is central or state, you first need to understand the structure of the GSTIN:
| Part of GSTIN | Description |
|---|---|
| 1st – 2 digits | State Code (e.g., 09 for UP) |
| 3rd – 12th | PAN of the business |
| 13th | Registration number under GST |
| 14th | Default “Z” for all |
| 15th | Checksum digit (for validation) |
Example:
09ABCDE1234F1Z5
- 09 = State Code (Uttar Pradesh)
- ABCDE1234F = PAN
- 1 = Registration number
- So, this GSTIN belongs to Uttar Pradesh (state).
This helps you determine the GST jurisdiction and whether the tax you’re paying is state (SGST) or central (CGST).
CGST vs SGST – What’s the Difference?
| Criteria | CGST | SGST |
|---|---|---|
| Collected by | Central Government | State Government |
| Applicable when | Intra-state supply | Intra-state supply |
| Share of tax | 50% of total GST | 50% of total GST |
| Example | GST = 18%, CGST = 9%, SGST = 9% | GST = 18%, CGST = 9%, SGST = 9% |
So, for any sale within a single state, both CGST and SGST are applicable in equal halves.
How to Know If My GST is Central or State?
You can identify the nature of your GST based on:
1. Type of Supply
- Within the same state, You pay CGST + SGST.
- Between two different states: You pay IGST (central).
2. GSTIN’s State Code
- The first two digits of your GST number indicate the state jurisdiction.
- You can refer to the list below to know your state code:
| State Name | GST Code |
|---|---|
| Maharashtra | 27 |
| Uttar Pradesh | 09 |
| Delhi | 07 |
| Gujarat | 24 |
| Rajasthan | 08 |
…and so on.
3. Invoice Pattern
- GST invoices clearly mention CGST, SGST, or IGST.
4. GST Portal
- Visit the GST portal and enter your GSTIN to verify registration and jurisdiction details.
