Make a GST tax invoice in seconds
Every registered business needs to issue a proper GST tax invoice — with the GSTIN, HSN/SAC codes, the taxable value, and the correct CGST + SGST (for a sale within your state) or IGST (for a sale to another state). This free generator does the maths for you: add your items and GST rate, choose intra- or inter-state supply, and download a clean invoice PDF with the tax split and the amount in words. It all runs in your browser, so your billing details are never uploaded.
One honest note: this creates a formatted invoice from what you enter — it doesn't validate your GSTIN or file anything. Always follow your accountant and the GST rules for your business.
How to make a GST invoice

- Choose intra-state (CGST + SGST) or inter-state (IGST), then add your items with quantity, rate and GST rate.
- Click Generate invoice (PDF) — the tax split, total and amount in words are filled in automatically.
Frequently asked questions
When is it CGST + SGST vs IGST?
A sale within your own state is CGST + SGST (split equally); a sale to a customer in another state is IGST. Choose the supply type and the tool splits the tax correctly.
Does it validate my GSTIN or file returns?
No — it formats an invoice from what you enter. GSTIN validation and filing happen on the GST portal.
Is my data uploaded?
No — the invoice is generated in your browser and never sent to a server.
