Free GST invoice generator
A compliant tax invoice, in your browser, with no account to create. It applies CGST and SGST or IGST from the place of supply rather than asking you to pick, converts the total to words, and tells you when the consignment is likely to need an e-way bill.

What Rule 46 actually requires
Sixteen particulars, and an invoice missing any of them is defective. In practice the ones that cause trouble are the last few, because they are the ones nobody thinks about until an officer reads the invoice back to them.
| Particular | Note |
|---|---|
| Name, address and GSTIN of the supplier | As per the registration certificate, not the trade name |
| Consecutive serial number | Unique for the financial year. Alphanumeric is fine; gaps are not |
| Date of issue | |
| Name, address and GSTIN of the recipient | Where registered |
| Name and address of the recipient, and the address of delivery, with State and State code | Where unregistered and the invoice value exceeds ₹50,000 |
| HSN or SAC code | 4, 6 or 8 digits by turnover — see below |
| Description, quantity, unit | |
| Total value, taxable value after discount | Discount must be shown, not netted silently |
| Rate and amount of tax — CGST, SGST, IGST, cess | Separately for each |
| Place of supply with State name | Mandatory for inter-state supply. Commonly omitted |
| Address of delivery where different from place of supply | |
| Whether tax is payable on reverse charge | Must be stated explicitly, even when it is "No" |
| Signature or digital signature | Not required where the invoice is issued electronically per Rule 46 proviso |
HSN digits
Four digits up to ₹5 crore of aggregate turnover in the preceding financial year, six digits above it, eight for exports. Businesses up to ₹5 crore may leave HSN off B2C invoices but not off B2B. The threshold looks at last year's turnover, so a business that crossed ₹5 crore in 2025-26 needs six digits from 1 April 2026 — a change that catches people mid-year.
Rates after GST 2.0
The 56th Council replaced five slabs with four — 0, 5, 18 and 40 per cent — and the 12% slab is abolished. Compensation cess ended in February 2026. Historic invoices still need 12% and 28%, which is why those options remain in the rate selector, but a fresh invoice raised today should not be using them. If your invoices are still going out at the old rates, the classification review is overdue.
When you also need an e-way bill
Broadly, where goods are being moved and the consignment value exceeds ₹50,000. The intra-state threshold is a State matter and Rajasthan's position differs from the national default, so confirm the current State notification rather than assuming. Movement without a required e-way bill exposes the consignment to detention and to penalty under section 129 — which is assessed on the goods, not on your convenience.
Common questions
What must a GST tax invoice contain?
Rule 46 lists sixteen particulars. The ones most often missed are the place of supply with the State name where the supply is inter-state, the HSN or SAC code, whether tax is payable on reverse charge, and a consecutive serial number unique for the financial year. A defective invoice gives an officer a clean reason to deny your customer's credit, which becomes your commercial problem before it becomes a tax one.
When do I charge IGST instead of CGST and SGST?
It follows the place of supply, not the customer's address on your ledger. Where the place of supply and the supplier's location are in different States or Union Territories, it is IGST. Where they are in the same State, it is CGST plus SGST. This tool decides it from the place of supply you select, which is why that field matters more than it looks.
How many digits of HSN code do I need?
Four digits where aggregate turnover in the preceding financial year was up to ₹5 crore, and six digits above that. Businesses up to ₹5 crore may omit HSN on B2C invoices, but not on B2B. Exports require eight digits. Getting this wrong is a common ground for an invoice being treated as defective.
Is this invoice generator really free, and is my data stored?
Yes and no, respectively. There is no signup, no account and no upload. Everything computes in your browser and nothing is transmitted anywhere. Close the tab and it is gone — which also means saving the PDF is on you.
Do I need an e-way bill for this consignment?
Generally where the consignment value exceeds ₹50,000 and goods are being moved, though the intra-state threshold varies by State and Rajasthan's own position differs from the national default. The tool flags when a check is likely to be needed; confirm the current State notification before relying on it.
Can I use this instead of accounting software?
For occasional invoicing, yes. For a business raising invoices regularly it is a poor substitute — you get no numbering continuity, no ledger, no GSTR-1 export and no record if the department asks. Use it to raise an invoice today, and move to proper books before the volume makes reconstruction expensive.
