When do I charge CGST plus SGST instead of IGST?

When your place of business and the client's place of supply are in the same state, the tax splits into CGST and SGST at half the rate each. When the client is in a different state, you charge IGST at the full rate. This generator switches automatically once you select both states.

What SAC code do freelancers use on a GST invoice?

SAC (Services Accounting Code) identifies the type of service supplied. Freelancers commonly use codes in the 9983 and 9984 families for professional, technical and IT services. Choose the code that genuinely matches your service and verify it on the GST portal before filing.

Is this GST invoice generator really free?

Yes. No signup, no watermark, no cap on the number of invoices. Everything runs inside your browser, so client names and amounts never reach any server.

How do I export the invoice as a PDF?

Click Download PDF. Your browser's print dialog opens with the invoice already laid out for A4. Choose Save as PDF as the destination. Only the invoice prints, not the form or the surrounding page.

How to make a GST invoice as a freelancer

Enter your business details. Name, address, state and GSTIN if you are registered. These are saved on your device, so the next invoice starts pre-filled.
Enter the client and the place of supply. The place of supply is what decides the tax split, not where you happen to be sitting.
Add your line items with a SAC code, quantity and rate. For a fixed-price project, one line with quantity 1 is fine.
Check the tax banner. Same state shows CGST + SGST at half the rate each. Different state shows IGST at the full rate.
Click Download PDF and choose "Save as PDF" in the print dialog.

Keep invoice numbers in one unbroken series across the financial year. Gaps and duplicates are the first thing that gets questioned during a review.

What a GST tax invoice must carry

Supplier name, address and GSTIN
A unique, sequential invoice number and the invoice date
Recipient name, address, and GSTIN where the recipient is registered
Place of supply, and the state code for inter-state supply
Description of service, SAC code, quantity, rate and taxable value
Tax rate and amount, split into CGST/SGST or shown as IGST
Total invoice value, commonly also written in words
Signature or digital signature of the supplier or an authorised person

This is a general checklist for the common freelancer case, not tax advice. Rules differ for exports, reverse charge, e-invoicing thresholds and composition dealers. Confirm your own position with a chartered accountant or on the official GST portal.

Frequently asked questions

Do I need a GSTIN to invoice as a freelancer?

Not always. Below the GST registration threshold for services you can raise a simple bill of supply without charging GST. Once you are registered, you must issue a GST tax invoice carrying your GSTIN. Thresholds change, so check your current position with a CA or on the GST portal.

When is it CGST + SGST, and when is it IGST?

Same state as the client → the tax splits into CGST and SGST at half the rate each (18% becomes 9% + 9%). Different state → a single IGST line at the full rate. This tool switches the moment you change either state dropdown.

Which SAC code should I use?

SAC identifies the type of service. Freelancers commonly sit in the 9983 and 9984 families covering professional, technical and IT services. Pick the code that genuinely matches what you delivered, and verify it on the GST portal before you file.

Can I invoice a foreign client with this?

You can produce the document, but export of services has its own treatment — LUT, zero rating and FIRC handling are outside what a generic generator can decide for you. Talk to a CA before you send an export invoice.

Is my client data uploaded anywhere?

No. There is no server and no analytics on this page. Everything is computed in your browser, and only your own business details are stored locally so the next invoice starts pre-filled. Clearing your browser data removes them.

Does it work offline?

Yes. Once the page has loaded, you can disconnect and keep generating invoices. You can also save the page to your computer and open it directly.
