Section 44
GST tax invoice
Use it when you are registered under GST and sell taxable goods or services.
Know before you sign
- Rule 46 of the CGST Rules, 2017 lists what a tax invoice must show: supplier's name, address and GSTIN; a serial number; date; buyer's name, address and GSTIN or UIN if registered; HSN code; description; quantity and unit; total value; taxable value after discount; tax rate and tax amount; place of supply for inter-state supply; delivery address if different; whether tax is on reverse charge; and the signature or digital signature of the supplier or authorised representative.
- The invoice number must be consecutive, not more than 16 characters, and unique for the financial year. It may use letters, numbers, hyphen (-) and slash (/).
- If the buyer is not registered and the taxable value is ₹50,000 or more, the invoice must show the buyer's name and address, the delivery address, and the name of the state with its code. Below ₹50,000, show these if the buyer asks.
- Charge either CGST plus SGST/UTGST, or IGST, depending on whether the supply is within your state or to another state. Leave the unused tax lines blank and ask your accountant if unsure.
- The number of HSN digits you must show depends on rules notified by CBIC for your class of taxpayer. Check the current notification on the GST portal.
- If your turnover makes e-invoicing compulsory for you, generate the invoice through the Invoice Registration Portal so it carries the QR code with the Invoice Reference Number (IRN). A signature is not needed on an electronic invoice issued under the Information Technology Act, 2000.
- For exports or supplies to SEZ units, Rule 46 requires a specific endorsement on the invoice and the country of destination. Use your accountant's export format for these.
