Questions
What must a GST tax invoice show?
Under CGST rule 46: the supplier's name, address and GSTIN; a serial number of up to 16 characters, unique for the financial year; the date; the buyer's name, address and GSTIN if registered; HSN or SAC; description, quantity and unit; taxable value; the tax rate and amount for each tax; the place of supply for inter-State supplies; whether tax is payable on reverse charge; and the supplier's signature.
How many HSN digits do I need?
Four digits if your turnover last year was up to ₹5 crore (optional on bills to unregistered buyers), six digits above ₹5 crore (Notification 78/2020-Central Tax, from 1 April 2021).
What if the buyer is not registered?
Leave the GSTIN blank. If the taxable value is ₹50,000 or more, the invoice must still show the buyer's name, address and State (CGST rule 46(e)).
I am not registered under GST. Can I use it?
Yes — leave your GSTIN blank and it makes a plain bill without GST. A composition dealer ticks "Composition scheme" to make a bill of supply.
