Frequently asked questions

What is a GST tax invoice?

A GST tax invoice includes supplier and buyer GSTIN (when registered), HSN/SAC codes, taxable value, GST rate and tax amount (CGST, SGST or IGST) as required under Indian GST law.

When do I use IGST vs CGST and SGST?

Same-state sales split tax into CGST and SGST (each half the rate). Inter-state sales use IGST at the full rate.

Is this a legally valid GST invoice?

This tool helps format invoices correctly, but you must ensure all mandatory fields under GST rules are filled and your registration details are accurate. Consult a tax professional for compliance.
