What Is a GST Invoice Format?

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.

Quick Tip: A good GST invoice should make it easy for the customer, accountant and business owner to understand who sold what, at what value, which tax applies and how much is payable.
