GST Invoice Generator – Free Tax Invoice PDF

Make a GST invoice in minutes

Freelancers, shopkeepers and small businesses need proper tax invoices — but accounting software can be expensive and complicated. This free GST invoice generator creates a clean, professional tax invoice with all the details GST rules ask for: GSTINs (validated as you type), HSN/SAC codes, CGST and SGST or IGST worked out automatically from the place of supply, a GST summary for mixed rates, round-off and the total in words. Download it as a PDF or print it, and your business details are remembered for the next invoice.

How to create an invoice

Fill in your business details and GSTIN once — tick “Remember” to keep them.
Add the customer's details and state (this decides CGST + SGST or IGST).
Add items with HSN/SAC code, quantity, rate and GST rate.
Check the preview, then Download PDF or Print. Use “New” for the next invoice number.

Example

A web designer in Pune (Maharashtra, state code 27) bills a client in Bengaluru (Karnataka, 29) ₹25,000 for website design (SAC 998314) at 18%. Because the place of supply is another state, the invoice shows IGST ₹4,500and a total of ₹29,500 — “Rupees Twenty-Nine Thousand Five Hundred Only”. Billing a client in Mumbai instead, it would show CGST ₹2,250 + SGST ₹2,250.

Good invoicing habits

Number invoices consecutively within each financial year (for example INV/26-27/001).
Check the HSN/SAC code and rate for each item — rates changed under GST 2.0 in September 2025.
Keep copies of every invoice for your GST returns.
Work out GST on a single amount with the GST calculator; send estimates first with the quotation maker.

Frequently asked questions

What must a GST tax invoice include?

Under the CGST Rules a tax invoice needs: the supplier’s name, address and GSTIN; a consecutive invoice number (up to 16 characters) unique in the financial year; the date; the recipient’s name and address (and GSTIN if registered); HSN or SAC codes; description, quantity and value of goods or services; the taxable value; the GST rate and amount (CGST + SGST, or IGST); the place of supply for inter-state supplies; whether tax is payable on reverse charge; and a signature. This generator includes all of these fields.

When do I charge CGST + SGST and when IGST?

If you and the place of supply are in the same state, the GST is split equally into CGST and SGST (UTGST in union territories). If the place of supply is another state, the whole tax is IGST. The generator decides automatically from your state and the customer’s state.

Is the invoice saved anywhere?

Only on your device. Your business details can be remembered for next time, and your last invoice is kept so you don’t lose work. Nothing is uploaded to our servers.

Do I need e-invoicing (IRN)?

Businesses above the e-invoicing turnover limit must report B2B invoices to the Invoice Registration Portal and print the IRN and QR code on them. This tool creates regular invoices; if e-invoicing applies to you, generate the IRN through the official portal or your accounting software.

Can I use it if I’m not registered under GST?

Yes — untick “Include GST” to make a simple invoice without tax. Unregistered businesses must not charge GST or call their bill a “tax invoice”.
