GST invoice format for freelancers (with a ₹ example)

"Bhaiya, invoice bhej do with GST number. Accounts needs it today." The work is done, the client is happy, and now you're staring at a blank Word file wondering what a proper tax invoice is supposed to have on it.

This guide gives you a GST invoice format for freelancers that you can copy: every field the law asks for, a filled-in ₹ example for a client in your state and one in another state, and what to do if you aren't GST-registered at all.

The short answer: if you're GST-registered, your tax invoice must show your name, address and GSTIN; a unique invoice number for the financial year; the date; the client's name, address and GSTIN (if they have one); the SAC code and a description of the work; the taxable value; the GST rate and amount (CGST + SGST, or IGST); the place of supply; whether reverse charge applies; and your signature. These come from Rule 46 of the CGST Rules, 2017 (CBIC). If you aren't registered, you send a normal invoice and don't charge GST.

This is general information, not tax advice. Your CA should confirm your rate, SAC code and registration position.

First, check: should your invoice have GST at all?

Only a GST-registered person can charge GST. Section 32 of the CGST Act says a person who isn't registered "shall not collect" any amount by way of tax. You can read the Act on CBIC's GST Acts page.

So there are two kinds of freelancer invoice:

Whether you must register depends mainly on your aggregate turnover in the financial year (April to March). For most service providers the threshold is ₹20 lakh, and it's lower in a few special-category states. There are other triggers too, so if you're close to the limit or invoice foreign clients, talk to your CA before you decide.

A common worry: "The client asked for a GST invoice, but I'm not registered." Tell them plainly. A plain invoice is still a valid bill for your work. The client just can't claim GST credit on it, because no GST was charged.

GST invoice format for freelancers: every field explained

If you are registered, here is each field from Rule 46 in plain words, in the order it usually appears on the page.

Your details (top of the invoice)

• Your name and address as on your GST registration certificate. A studio or brand name can sit next to it, but not instead of it.
• Your GSTIN, all 15 characters.
• The words "Tax Invoice" as the heading, so nobody mistakes it for a quotation.

Invoice number and date

• A consecutive serial number, unique for the financial year, up to 16 characters. Letters, numbers, hyphens and slashes are allowed. For example: PS/26-27/014.
• Date of issue. For services, Rule 47 says the invoice should be issued within 30 days of supplying the service.

Never skip or reuse a number. If an invoice was wrong, your CA will usually tell you to correct it with a credit or debit note rather than deleting it and reusing its number.

Client details

• Client's name and address.
• Client's GSTIN, if they are registered. This is what lets a business client claim the GST you charged as input tax credit, so double-check every character.
• If the client isn't registered and the taxable value is ₹50,000 or more, Rule 46 also asks for their address and their state's name and code.

What you did

• SAC code. Services use SAC (Services Accounting Code). A lot of design, development, marketing and consulting work falls under heading 9983 ("other professional, technical and business services"), but confirm the exact code for your service with your CA.
• Description. Write the deliverable the way it appeared in your approved quote: "Logo design, 3 concepts, 2 revision rounds" is much better than "Design work". It's easier for the client's accounts team to match, and it ties back to what was agreed.
• Taxable value. Your fee before GST, after any discount you gave.

The tax

• Rate and amount of tax, shown separately. Most services under heading 9983 are taxed at 18%, as amended by Notification 15/2025-Central Tax (Rate) from 22 September 2025. Check the rate for your exact service.
• Client in your state: split it into CGST (9%) and SGST (9%).
• Client in another state: charge IGST (18%).
• Place of supply. For a registered business client this is usually the state where the client is registered. Write the state's name and code.
• Reverse charge: Yes or No. For almost all freelance work it's "No", but the line must be there.

The close

• Total in figures (many people add it in words too).
• Signature or digital signature. A signed PDF works.

Rule 46 doesn't require these, but put them in anyway: your bank account and IFSC, your UPI ID, the payment due date and the quote or project it relates to. A client who has to ask "where do I pay?" pays later.

A filled-in example (client in your state)

Example only: a freelance designer in Pune, Maharashtra, billing a café chain also registered in Maharashtra. The GSTINs are placeholders.

Below the total: "Rupees fifty-six thousand six hundred and forty only", your bank and UPI details, "Payment due: 26 Nov 2026", and your signature.

The same invoice for a client in another state

Now the café chain is registered in Karnataka, with its office in Bengaluru. Everything stays the same except the place of supply and the tax lines:

Place of supply: Karnataka (29). The total doesn't change. Only the type of tax does, and that decides how the client claims the credit and how you report it. Putting CGST and SGST on an inter-state invoice is one of the most common mistakes, so look at the state codes before you send.

Invoicing extra work and change orders

If the client approved extra work mid-project, put it on the invoice as its own line, with its own description. For example, "Change order 1: 6 additional posts (approved 5 Nov)". It's taxed at the same rate as the main work. If you haven't set that up yet, our change order template shows how to get the extra price approved before you start. Paid extra revision rounds work the same way, as explained in how many revisions should a freelancer include.

Keep each line tied to something the client approved in writing. It's the quickest way to answer "what is this ₹6,000 for?" from an accounts team that never saw your WhatsApp chat.

Mistakes that get freelance invoices sent back

• Charging GST without being registered. Not allowed. Send a plain invoice.
• Missing or wrong client GSTIN. The client can't claim credit, so their accounts team returns it.
• CGST + SGST for an out-of-state client (or IGST for a local one).
• Gaps or repeats in invoice numbers, or restarting the series in the middle of a financial year.
• No SAC code, or one copied from a template that doesn't match your work.
• "Professional charges" as the only description. Use the deliverables from your quote.
• Invoicing months after the work. For services the rule is 30 days from supply.
• No payment details or due date. It's not a legal field, but it's the one that gets you paid.

Doing this without a pile of PDFs

The whole system is simple: the invoice carries the same deliverables the client approved, extra work appears as its own approved line, and numbering never breaks. In ScopeFlow, you write the quote with deliverables and GST, the client approves it through a private link, and you can raise GST tax invoices with CGST + SGST or IGST, locked numbering and a UPI QR code. Part payments and what's still due are tracked in one place. It's in beta, and the Free plan covers 2 active projects and 5 clients, so you can start free or see pricing.

FAQ

Do I need a GST number as a freelancer?

Only if you have to register, which depends mainly on your aggregate turnover in the financial year (₹20 lakh for most service providers, lower in a few special-category states), plus some other triggers. Below that, registration is optional. Ask your CA if you're close to the limit or invoice foreign clients.

Can a freelancer send an invoice without GST?

Yes. If you aren't GST-registered, send a plain invoice with no GST and no GSTIN. Under section 32 of the CGST Act, an unregistered person must not collect GST.

What is the GST rate for freelance services?

Most professional, technical and business services under SAC heading 9983 are taxed at 18%. That's CGST 9% + SGST 9% for a client in your state, or IGST 18% for one in another state. Confirm the rate for your exact service.

What SAC code should a freelancer use?

It depends on the service. Much design, development, marketing and consulting work falls under heading 9983, but the exact code varies, so check it with your CA and use the same code consistently.

When should a freelancer issue a GST invoice?

For services, Rule 47 of the CGST Rules says within 30 days of supplying the service. In practice, invoice as soon as a milestone or the project is delivered.
