A tax invoice with CGST and SGST or IGST worked out for you, ready to print or save as PDF. It all happens on your device; nothing is uploaded.
The rules this invoice follows
- The fields are the ones Rule 46 of the CGST Rules, 2017 asks a tax invoice to carry, including a serial number of at most 16 characters (letters, digits, "-" and "/"), unique for the financial year, and whether tax is payable on reverse charge.
- When your state, taken from the first two digits of your GSTIN, is the same as the place of supply, the invoice charges CGST and SGST at half the rate each; in a union territory without a legislature, UTGST takes the place of SGST. Otherwise it charges IGST at the full rate. The place of supply starts as your customer's state; change it if the goods are delivered, or the service is supplied, somewhere else.
- The rates are the ones in force since 22 September 2025, after the 56th GST Council meeting cut the main rates to 5% and 18%, with 40% for a few goods, plus the special rates kept for precious metals, diamonds and stones and supplies to merchant exporters.
- Tax is worked out on the taxable value of each rate, rounded to the paisa, and the total is rounded to the nearest rupee, with the difference shown as round off. GSTINs are checked for their format, state code and check character, which catches most typos; it can't tell you whether a GSTIN is active.
- This is a convenience, not tax advice. Check anything you're unsure of with your accountant. Your business details are remembered in this browser to save typing next time; nothing leaves your device.
Questions
What must a GST tax invoice contain?
Under Rule 46 of the CGST Rules, 2017: the supplier's name, address and GSTIN; a serial number of up to 16 characters; the date; the recipient's name, address and GSTIN if registered; the HSN or SAC code, description, quantity and unit; the taxable value; the tax rate and amount of each tax; the place of supply with the state's name for inter-state supplies; whether tax is payable on reverse charge; and the supplier's signature.
When do I charge IGST instead of CGST and SGST?
When the supplier's state and the place of supply are different, the supply is inter-state and carries IGST at the full rate. When they are the same, it carries CGST and SGST at half the rate each, or CGST and UTGST in a union territory without a legislature.
How long can a GST invoice number be?
At most 16 characters, using letters, digits, hyphens and slashes, and unique within a financial year. That is Rule 46(b) of the CGST Rules, 2017.
What are the GST rates after September 2025?
From 22 September 2025, most goods and services are taxed at 5% or 18%, with 40% for a few luxury and sin goods. Special rates remain, such as 3% for gold, silver and jewellery and 0.25% for rough diamonds.
Do I need the GSTIN of an unregistered customer?
No, an unregistered customer has none. If the taxable value is ₹50,000 or more, Rule 46(e) asks for their name, address, and the state and its code instead.
