The "Export Means No GST" Myth — Why Freelancers with Foreign Clients Still Need GST + an LUT

Here's a scenario we see constantly: a freelance developer, designer, or consultant bills only foreign clients, gets paid in dollars or another foreign currency, crosses ₹20 lakh in a year, and assumes none of it matters for GST because "export of services means zero GST." That belief is technically half true — and the missing half is exactly where the exposure sits.

What's actually true: exports of services are a 'zero-rated supply' under the IGST Act — meaning the GST rate applicable to them is effectively 0%, and this is a genuine, real benefit. What's false: 'zero-rated' does not mean 'outside GST law' or 'no registration needed.' Zero-rated supply is a category within GST law, not an exemption from it. You still cross the same ₹20 lakh services threshold, and once you do, GST registration is mandatory — export income counts toward that turnover exactly like domestic income does.

So what happens if you skip registration anyway, thinking exports don't count? The same consequences as any other unregistered business past the threshold — a Section 122 penalty (₹10,000 or the tax amount due, whichever is higher), backdated liability, and interest. Except here there's an added twist: you also lose access to the export-specific benefits that make zero-rating actually work for you.

The second half of the myth — and the more expensive one. Even after you register, if you don't separately file a Letter of Undertaking (LUT), you're required to pay IGST upfront on every export invoice and then apply separately for a refund. For a freelancer or consultant billing foreign clients regularly, this is a genuine cash-flow problem — you'd be fronting tax on income you haven't even collected yet, then waiting on a refund cycle to get it back.

What an LUT actually does. Filed as Form RFD-11 under Rule 96A of the CGST Rules, an LUT is your formal undertaking that you'll meet the export conditions — and once accepted, it lets you invoice foreign clients without paying IGST upfront at all. It's valid for one financial year and must be renewed at the start of each new year; to file one, you need to be GST-registered with no major default or prosecution history above the prescribed threshold.

Put together, the correct sequence for a freelancer with foreign clients is: register for GST once you cross ₹20 lakh (or immediately if any other compulsory-registration trigger applies to you), file your LUT before raising your next export invoice, and keep your FIRC or foreign remittance certificates on file for each payment as proof of export. Skip either registration or the LUT, and you're either exposed to penalties or unnecessarily funding IGST out of your own pocket while you wait for a refund.

If you're a freelancer or consultant working with international clients and unsure whether you've already crossed the threshold, or need your GST registration and LUT filed together so there's no gap between them, that's precisely what our GST registration service is built to sort out in one pass.
