GST invoice format: what a tax invoice must include

Seller and invoice details

• Your business name, address and 15-character GSTIN.
• A unique invoice number for the financial year, up to 16 characters (letters, numbers, "-" and "/"). For example INV/26-27/001.
• The invoice date.

Buyer details

• The buyer’s name and address, and GSTIN if they are registered.
• For unregistered buyers, the name, address and state are needed for larger invoices (commonly above ₹50,000).
• Place of supply (state name and code), and the delivery address if it differs from the billing address.

Item and tax details

• Description, quantity and unit of each item.
• HSN code for goods or SAC code for services. The number of digits required depends on your turnover — larger businesses must show longer codes, so check what applies to you.
• Taxable value (after any discount) and GST rate for each item.
• CGST + SGST when the seller and place of supply are in the same state; IGST when they are in different states.
• The total, ideally also in words.
• Whether tax is payable on reverse charge.
• Signature or digital signature of the supplier or authorised person.
