HSN Code on Invoice

Many small businesses might find it cumbersome to find and update HSN code for the goods supplied. Hence, to reduce the compliance burden of small businesses, the GST Council has relaxed the requirement for displaying HSN code on invoices based on the sales turnover. As per Notification No. 12/2017 – Central Tax dated 28th June 2017, the concerned individual shall display the HSN code on the invoice by the following:

  • Entities having less than Rs.1.5 crores annual turnover in the preceding financial year will not be required to display the codes on the invoice.
  • Entities having Rs.1.5 crores to Rs.5 crores annual turnover in the preceding financial year will be required to display the first two-digit (Chapter) of the HSN code on the invoice.
  • Entities having more than Rs.5 crore as annual turnover in the preceding financial year should display the first two-digit (Chapter) and chapter heading of the HSN code on the invoice. Thus, only entities having more than Rs.5 crore of annual turnover shall display 4 digit the codes as displayed in the invoice.
