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 (8511) on tax invoices to registered buyers (optional on B2C invoices); above ₹5 crore, at least 6 digits (851150) on all tax invoices. Exports and imports are declared on the shipping bill or bill of entry under the full 8-digit tariff item (85115000), so most exporters print 8 digits on their GST invoices too.
The HSN-wise summary in GSTR-1 uses the same code, so set it once on the item in your billing software. FundRaksha Book stores the HSN and GST rate on each item, splits CGST, SGST and IGST on every bill, and keeps stock and party ledgers alongside.
