GST Invoice Format in India: What a Tax Invoice Must Include

A GST tax invoice is more than a bill. It carries details that your customer needs to claim input tax credit, and that you need for your returns. Here is what to include.

Details on a tax invoice

• Your name, address and GSTIN.
• A unique invoice number in a running series, and the date.
• The customer’s name, address and GSTIN (if they are registered).
• For each item: description, HSN/SAC code, quantity, rate and taxable value.
• The GST rate and amount, split into CGST and SGST, or IGST.
• The total and the place of supply.
• A signature or digital signature of the supplier.

CGST + SGST or IGST?

If you and the place of supply are in the same state, charge CGST and SGST (half each). If they are in different states, charge IGST. The Invoice Generator works this out when you choose the type.

Formats you can start from

• GST invoice format with HSN, tax split and bank details.
• Shop bill format for retail, with different GST rates per item.
• Freelancer invoice with no GST.
• Quotation format to send before the invoice.

Tips

1. Do not skip invoice numbers, and do not reuse them.
2. Keep a copy of every invoice, in print or on your computer.
3. Add your bank details and UPI so customers can pay quickly.
