Zero-Rated Revenue: The Freelancer’s 2026 Guide to GST for Foreign Clients and LUTs

The US-India Freelance Corridor: Why GST Matters Now

For a remote developer based in India working for a US-based startup or agency, the dream is often high-margin revenue paid in USD. However, as the 2026 fiscal year approaches, the complexity of the GST (Goods and Services Tax) regime can turn that dream into a bureaucratic headache. The most common GST compliance question for remote developers working for foreign organizations is how to handle the 18% Integrated GST (IGST) that normally applies to services.

The good news is that under Indian law, providing services to a client outside of India is classified as an "Export of Service." This qualifies as zero-rated supply, meaning you don't have to charge your US client tax, nor do you have to pay it out of your own pocket—provided you follow the correct procedural steps. At My Advisers, we see many freelancers lose 18% of their top-line revenue simply because they haven't filed a Letter of Undertaking (LUT). In this guide, we will break down the mechanics of the LUT and how to ensure your US-India workflow remains tax-efficient.

Defining 'Export of Services' for Remote Work

To treat your income as "zero-rated," the transaction must meet five specific criteria under Section 2(6) of the IGST Act:

• The supplier (you) is located in India.

• The recipient (your client) is located outside India.

• The place of supply is outside India (generally where the client is located for service contracts).

• Payment is received in convertible foreign exchange (USD, GBP, etc.) or in INR where permitted by the RBI.

• The parties are not merely establishments of the same person.

If you fail to meet even one of these—for instance, if you receive payments in INR through a domestic payment aggregator that doesn't provide a Foreign Inward Remittance Certificate (FIRC)—the tax department may reject your export status. My Advisers helps developers audit their payment gateways to ensure every dollar earned is recognized as a valid export.

The Power of the LUT: Avoiding the 18% Hit

The Letter of Undertaking (LUT) is your most powerful tool. Without it, you are required to pay 18% IGST upfront on every invoice and then apply for a refund from the government later—a process that can take months and stifle your cash flow.

By filing an LUT (Form GST RFD-11) at the start of the financial year, you "undertake" to fulfill the export requirements without paying the tax upfront.

Why the LUT is Essential for US Contracts:

1. Cash Flow Preservation: You keep 100% of your invoice value immediately.

2. Competitive Pricing: You don't have to explain Indian tax surcharges to a US client who likely won't understand them.

3. Simplified Invoicing: Your invoices will clearly state: "Supply meant for export under bond or LUT without payment of integrated tax."

At My Advisers, our platform automates the annual LUT filing for remote developers, ensuring you never miss the deadline at the start of the new fiscal year.

Reporting Zero-Rated Revenue: GSTR-1 and GSTR-3B

While you may be exempt from paying tax, you are not exempt from filing returns. Even with zero-rated revenue, you must file:

• GSTR-1: Where you report all your export invoices. You must ensure the invoice numbers, dates, and shipping bill (or FIRC details) are accurately logged.

• GSTR-3B: The monthly or quarterly summary where you declare your zero-rated turnover.

A common pitfall for US-based freelancers is the FIRC (Foreign Inward Remittance Certificate). When your US client pays via a wire transfer or a platform like Wise or Payoneer, you must collect the FIRC from your bank. This document is the legal proof that you received "convertible foreign exchange." Without it, your zero-rated claims are vulnerable during an audit. My Advisers provides a dedicated compliance dashboard to help you track these certificates against your monthly filings.

Should You Register Even if You Are Below the Threshold?

Many developers believe that if their revenue is under the ₹20 Lakh (approx. $24,000 USD) threshold, they can ignore GST entirely. While legally true for domestic work, there are three reasons to register anyway:

1. Platform Requirements: Companies like Google (AdSense), Apple (App Store), and Upwork often require a GSTIN to avoid withholding taxes or to verify business accounts.

2. Input Tax Credit (ITC): As a registered taxpayer, you can claim back the GST you pay on your laptop, internet bills, and software subscriptions (like AWS or Adobe Creative Cloud). This effectively gives you a ~18% discount on your business expenses.

3. Professionalism: A GSTIN signals to large US clients that you are a legitimate business entity, which is often a prerequisite for high-value B2B contracts.

Whether you choose a Sole Proprietorship or a Private Limited Company, having a clear tax structure is the first step toward scaling your remote agency.
