What is a GST Invoice?
A GST invoice is a bill that a seller issues to a buyer when goods or services are sold under India’s Goods and Services Tax (GST) system. It records the transaction and shows the amount of tax charged — whether CGST, SGST, or IGST.
In simple terms, a GST invoice is proof of sale and ensures that the right tax is collected and reported.
GST Invoice Format: Key Details You Must Include
A GST-compliant invoice must have the following details:
- Seller’s name, address, and GSTIN
- Buyer’s name, address, and GSTIN (if registered)
- Invoice number and invoice date
- Description of goods or services
- HSN Code (for goods) or SAC Code (for services)
- Quantity and unit
- Taxable value (before GST)
- Rate and amount of CGST, SGST, or IGST
- Total invoice value (including tax)
- Place of supply and state
- Signature or digital signature of the seller
GST Invoice Example
Here’s a simple example of how GST is calculated:
| Description | Amount (₹) |
|---|---|
| Product Value | 10,000 |
| CGST @9% | 900 |
| SGST @9% | 900 |
| Total Invoice Value | 11,800 |
If you’re selling to another state, IGST (18%) would apply instead of CGST + SGST.
