As an un-registered taxable person now, am I required to furnish information like HSN, place of supply, taxable value, etc in my invoice? (I know that it is mandatory for a tax invoice only)

1. HSN codes, taxable value, place of supply are required to be recorded in a tax invoice to be issued by a registered person under rule 46 of the CGST Rules, 2017.
2. An unregistered person cannot issue a tax invoice.
