GST Invoice Generator

Under Rule 46 of the CGST Rules, a tax invoice must include: seller name, address and GSTIN; a consecutive invoice number (up to 16 characters); date; buyer name, address and GSTIN (for B2B); HSN/SAC code (4 digits if turnover is up to ₹5 crore, 6 digits above that); description, quantity and unit; taxable value; GST rate and CGST+SGST (intrastate) or IGST (interstate) amounts; place of supply with state name; whether tax is payable on reverse charge; and a signature. Always consult a CA to ensure full compliance.

Use CGST + SGST when the seller's state (the first two digits of its GSTIN) is the same as the place of supply (intrastate). Use IGST when they differ (interstate). This tool picks the right one automatically when you enter the seller GSTIN and place of supply. The total GST rate is the same — only the split differs.

This tool generates a reference invoice for convenience. For official GST filings, the invoice must comply with GST Invoice Rules 2017. Consult a CA or use government-approved accounting software for legally binding invoices.

Since GST 2.0 (22 September 2025) the main rates are 5% and 18%, with a 40% rate for sin and luxury goods (aerated drinks, large cars, tobacco from 1 February 2026). Nil, 3% (gold/jewellery) and 0.25% (rough diamonds) continue. The 12% and 28% slabs no longer exist. Items on one invoice can carry different rates; this tool totals the tax separately for each rate.

Yes, if your aggregate annual turnover in any year since FY 2017-18 exceeded ₹5 crore: B2B invoices must be reported on the Invoice Registration Portal (IRP) to get an IRN and QR code. If turnover is ₹10 crore or more, the invoice must be reported within 30 days of its date. An invoice made with this tool alone is not an e-invoice.

For goods: invoice must be issued before or at the time of removal. For services: within 30 days of supply (45 days for banks/NBFCs). Late invoicing can attract penalties under GST law.
