What must a GST tax invoice contain?

Rule 46 of the CGST Rules requires the supplier's name, address and GSTIN; a consecutive invoice number and date; the recipient's name, address and GSTIN where registered; the HSN or SAC code; description, quantity and taxable value of the goods or services; the rate and amount of CGST, SGST, IGST and cess; the place of supply for an inter-state supply; whether tax is payable on reverse charge; and the supplier's signature or digital signature.

How do I decide between CGST plus SGST and IGST on an invoice?

Compare your own state with the place of supply. If they are the same, charge CGST and SGST at half the rate each. If they differ, charge IGST at the full rate. This generator picks the correct split automatically once you set both states.

Is an HSN code mandatory on an invoice?

Yes, for registered taxpayers. Businesses with aggregate annual turnover up to Rs 5 crore must report 4 digits on B2B invoices, and those above Rs 5 crore must report 6 digits. Services use the SAC code in the same way.

Can I use this invoice for filing GSTR-1?

The invoice itself is compliant, but this page does not file anything or keep a numbered series for you. GST law requires invoice numbers to be consecutive and unique within a financial year, and your books must carry every invoice you issue. For anything beyond an occasional invoice, use proper accounting software.

Where is my invoice data stored?

Only in your own browser. Your business details are saved to local storage on your device so you do not have to retype them, and nothing is ever uploaded to any server. Clearing your browser data removes them.

Reference

What a tax invoice must carry

Rule 46 of the CGST Rules — the fields below are all generated for you.

Supplier	Name, address and GSTIN
Number & date	Consecutive and unique within the financial year, up to 16 characters
Recipient	Name, address and GSTIN where registered; for unregistered B2C above ₹50,000, name, address and state are still required
HSN / SAC	4 digits up to ₹5 crore turnover, 6 digits above
Line detail	Description, quantity, unit, rate, discount and taxable value
Tax	Rate and amount of CGST, SGST/UTGST, IGST and cess, shown separately
Place of supply	Mandatory for an inter-state supply, with the state name
Reverse charge	A statement of whether tax is payable on reverse charge
Signature	Signature or digital signature of the supplier or an authorised person

This generator produces the invoice document only. It does not maintain your invoice series, write to your books, file GSTR-1, or generate an e-invoice IRN — all of which the law requires once you are registered and, for IRN, above the turnover threshold. It also does not determine the correct HSN classification or GST rate for what you supply, or handle export, SEZ, bill-of-supply or delivery-challan formats. Use it for a one-off invoice; use proper accounting software for a business.

Questions

Invoicing, answered

CGST + SGST or IGST?

Compare your state with the place of supply. Same state means CGST and SGST at half the rate each; different states mean IGST at the full rate. This page switches automatically once you set both.

Is the HSN code compulsory?

Yes for registered taxpayers — 4 digits on B2B invoices up to ₹5 crore turnover, 6 digits above it. Services use the SAC code the same way.

What invoice number should I use?

Anything up to 16 characters using letters, digits, slash and hyphen — but it must be consecutive and unique within the financial year. A gap or a repeat is a compliance problem, which is exactly what software is for.

Do I need an e-invoice IRN?

Only above the notified turnover threshold, and then for B2B supplies. Below it, a normal tax invoice like this one is fine.

How do I get a PDF?

Click Print and choose "Save as PDF" as the destination. The page is styled for A4 and everything except the invoice itself is hidden when printing.

Where does my data go?

Nowhere. It stays in the page, and "Remember my details" writes only to this browser's local storage. Nothing is uploaded.
