How many HSN digits to print on the invoice
Notification 78/2020-Central Tax sets the minimum by aggregate turnover in the previous financial year: up to ₹5 crore, at least 4 digits (3204) on tax invoices to registered buyers (optional on B2C invoices); above ₹5 crore, at least 6 digits (320413) on all tax invoices. Exports and imports are declared on the shipping bill or bill of entry under the full 8-digit tariff item (32041329), so most exporters print 8 digits on their GST invoices too.
