Frequently asked questions
What details are mandatory on a GST tax invoice in India?
A valid GST tax invoice must include: (1) supplier's name, address and GSTIN; (2) a consecutive invoice number and date; (3) buyer's name, address and GSTIN (if registered); (4) HSN/SAC code for each item; (5) description, quantity and unit of goods or services; (6) taxable value, applicable GST rate (CGST/SGST or IGST) and tax amount; (7) place of supply; and (8) the supplier's signature or authorised signatory.
What is the difference between CGST+SGST and IGST on an invoice?
When seller and buyer are in the same state (intra-state), GST is split equally into CGST (central) and SGST (state). When the sale crosses state lines (inter-state), a single IGST is charged at the full rate. The total tax burden is identical — only how it is divided changes.
When should I use HSN codes on an invoice?
HSN (Harmonised System of Nomenclature) codes are mandatory on B2B invoices for all GST-registered businesses. For B2C invoices, businesses with annual turnover above ₹5 crore must include 6-digit HSN codes; turnover ₹1.5–5 crore requires 4-digit codes; below ₹1.5 crore it is optional. Use the HSN Code Finder tool to look up the right code.
Can I add a discount on a GST invoice?
Yes. You can offer a line-level discount (applied before GST is calculated). GST is then computed on the post-discount taxable value. Use the per-line "Discount %" field in this generator — the live totals panel shows the discount amount and reduced taxable value.
