A GST invoice format is the standard structure used by a GST-registered business to record the sale of taxable goods or services. It contains important information about the seller, buyer, invoice, products or services, taxable value, applicable GST and final amount payable.
A properly prepared GST invoice normally includes details such as the supplier's GSTIN, invoice number, invoice date, customer details, description of goods or services, HSN or SAC information where applicable, taxable value and the applicable CGST, SGST or IGST.
The exact requirements can depend on the nature of the transaction and applicable GST rules. Businesses should use the format appropriate to their transaction rather than treating every invoice as identical.
Here is a simple GST invoice example showing the main sections commonly found in a professional tax invoice.

The basic structure of a GST invoice remains similar, but the information shown can differ depending on whether you are selling products or providing services.

|---|---|
| Product description | Service description |
| Quantity | Hours / project / service unit where applicable |
| Unit price | Service fee |
| HSN classification | SAC classification where applicable |

The GST components shown on an invoice depend on the nature and location of the supply.
Central Goods and Services Tax. It is generally charged along with SGST on eligible intra-state supplies.
State Goods and Services Tax. It is generally charged along with CGST on eligible intra-state supplies.
Integrated Goods and Services Tax. It is generally used for eligible inter-state supplies.
A GST invoice and a regular invoice can look similar, but their tax information and use can differ. A GST invoice contains the applicable GST details required for a taxable supply made under GST.
| GST Invoice | Regular Invoice |

| Used where GST requirements apply | May be used where GST is not applicable |
| Contains applicable GST details | GST fields may not apply |
| May show CGST, SGST or IGST | Usually does not contain GST tax components |
| Includes relevant GST identification details | GSTIN may not be required |
| Useful for GST accounting and tax records | Used for general billing where applicable |
