The essentials
Everything worth knowing about a GST invoice.
What must a GST invoice contain?
Under Rule 46 of the CGST Rules, a tax invoice issued by a registered supplier must include:
- Supplier’s name, address and GSTIN
- A consecutive, unique invoice number (max 16 characters) for the financial year
- Date of issue
- Recipient’s name, address and GSTIN (if registered)
- HSN code for goods or SAC for services
- Description, quantity and unit of goods or services
- Total value and taxable value after discounts
- Rate and amount of tax - CGST, SGST/UTGST, IGST and cess shown separately
- Place of supply with state name, for inter-state supplies
- Delivery address if different from the place of supply
- Whether tax is payable on reverse charge
- Signature or digital signature of the supplier
Use the Tax ID fields for GSTINs, item details for HSN/SAC, and custom fields for place of supply and reverse charge. A drawn signature is an image, not a certified digital signature. This tool does not validate GSTINs, classify supplies, file returns or register e-invoices. Check CBIC invoice rules and current notifications with your accountant. See our GST invoice format guide.
CGST + SGST or IGST?
In a typical taxable intra-state supply, CGST and SGST share the GST rate; inter-state supplies generally use IGST. Exports and other special cases require separate treatment. The presets are calculation shortcuts, not a determination of your applicable rate or place of supply. Confirm the correct treatment before using CGST + SGST or IGST.
