Question
How many HSN code digits must I show on a GST invoice?
Answer
Bottom line: It depends on turnover — 4 digits up to ₹5 crore and 6 digits above ₹5 crore.
1. Up to ₹5 crore
Show a 4-digit HSN on B2B invoices (optional on B2C).
2. Above ₹5 crore
Show a 6-digit HSN on all invoices.
3. Imports, exports and returns
Imports and exports need the full 8-digit code, and from May 2025 the HSN in GSTR-1 Table 12 must be picked from a dropdown, not typed.
