GST Invoice Generator (India)

Make a GST tax invoice in rupees with CGST and SGST split automatically. Add your GSTIN and HSN/SAC codes, then download a PDF.

Quick answer: A GST tax invoice must show the supplier's name, address and GSTIN, a unique serial number, the date, the recipient's details (and GSTIN if registered), HSN/SAC codes, taxable value, the GST rate and amount (CGST + SGST for intra-state sales, IGST for inter-state sales), and the place of supply.

CGST + SGST or IGST?

Sale typeTax to chargeExample at 18%
Within the same state (intra-state)CGST + SGST, half each9% CGST + 9% SGST
To another state (inter-state)IGST18% IGST

In the generator, set the tax name to GST and the rate to 18 (or 5, 12 or 28). Tick Split tax in half for intra-state sales to show CGST and SGST. For inter-state sales, change the tax name to IGST and untick the split.

  • Invoice date
  • Recipient name, address and GSTIN if registered, plus the place of supply with state name and code

FAQ

Is this a valid GST invoice format?

It includes the fields usually required on a tax invoice. Add your GSTIN, HSN/SAC codes and place of supply. E-invoicing (IRN) is mandatory only above the turnover threshold notified by the GST Council. Confirm your obligations with a CA.

How do I show CGST and SGST separately?

Set tax name to GST, enter the full rate (for example 18), and tick Split tax in half. The invoice shows CGST 9% and SGST 9%.

Can I make an invoice without GST?

Yes. If you're not GST-registered, set the tax rate to 0 and call it an Invoice or Bill of Supply as applicable.
