Worked example: a ₹1,000 sale under HSN 85021100
Taxable value ₹1,000.00. Within your state: CGST ₹90.00 + SGST ₹90.00 = ₹180.00, invoice total ₹1,180.00. To a buyer in another state: IGST ₹180.00, the same total.

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 (8502) on tax invoices to registered buyers (optional on B2C invoices); above ₹5 crore, at least 6 digits (850211) on all tax invoices. Exports and imports are declared on the shipping bill or bill of entry under the full 8-digit tariff item (85021100), so most exporters print 8 digits on their GST invoices too.
