GST RFD-11 (LUT) Filing Guide for FY 2026-27: For Freelancers & SaaS

Key Takeaways

• Zero-Rated Exports: Filing Form GST RFD-11 allows freelancers and SaaS founders to export services without paying Integrated GST (IGST) upfront, which is crucial for maintaining healthy working capital.
• Annual Compliance: A Letter of Undertaking (LUT) is valid for one financial year. For the financial year 2026-27, the LUT must be filed on or before March 31, 2026, to ensure uninterrupted zero-rated supplies from April 1, 2026.
• Mandatory for IGST Exemption: Without a valid LUT, an exporter must pay IGST on all export invoices and then claim a refund, a process that can be time-consuming and block funds. Filing an LUT is a mandatory prerequisite to export without IGST payment.
• Simplified Online Process: The entire process of filing Form GST RFD-11 is online through the GST portal and takes only a few minutes, requiring basic business details, two witnesses, and a digital signature (DSC or EVC).

PART 1: EXECUTIVE SUMMARY

This guide provides a detailed compliance framework for freelancers, digital nomads, and SaaS founders on filing Form GST RFD-11, the Letter of Undertaking (LUT), for the Financial Year 2026-27. The primary objective of an LUT is to facilitate the export of services without the upfront payment of IGST, a significant advantage for businesses operating on a global scale.

• The Old System: Before the current online system, and in the initial GST period, the process for exporting without tax payment was more cumbersome. It often involved manual submissions and the furnishing of bonds with bank guarantees, which created a considerable compliance burden and locked up capital for small businesses and freelancers.
• The New Law (GST Regime): Under the GST framework, Rule 96A of the CGST Rules, 2017, introduced a streamlined online procedure for filing an LUT via Form GST RFD-11. This declaration allows a registered taxpayer to make "zero-rated supplies" (i.e., exports and supplies to SEZs) without paying IGST. The GST Network (GSTN) has enabled the filing for FY 2026-27, which must be completed by March 31, 2026, for the upcoming financial year.
• Who is Impacted: This compliance is critical for any GST-registered service provider in India with international clients. This includes SaaS companies, freelance developers, consultants, designers, and digital nomads who provide services to recipients located outside India. Filing an LUT is the most efficient mechanism for these entities to manage cash flow and remain competitive in the global market.

PART 2: DETAILED TAX ANALYSIS

1. Tax Landscape for SaaS & Digital Nomads

For SaaS companies and digital nomads based in India, the primary business model involves the "export of services." Under the GST law, the export of services is classified as a zero-rated supply. This means that while the service itself is taxable, the tax rate on the final export transaction is zero. The supplier can also claim a refund of the input tax credit (ITC) on inputs and services used to provide these exports.

There are two methods to handle zero-rated supplies:

• Export with Payment of IGST: The supplier pays IGST on the export invoice and later claims a refund of the tax paid. This method can block significant working capital, especially for businesses with high-volume or high-value transactions.
• Export without Payment of IGST: The supplier files a Letter of Undertaking (LUT) in Form GST RFD-11. This is a declaration promising to fulfill all export-related obligations under GST law. Once filed, the supplier can issue export invoices without charging IGST for the entire financial year.

For SaaS founders and freelancers, the LUT route is almost always preferable. It directly supports cash flow by eliminating the need to pay tax and wait for a refund. This financial liquidity is paramount for scaling operations and managing the day-to-day expenses of a location-independent business.

2. Direct Tax vs. GST Interplay

A common point of confusion is the relationship between GST (an indirect tax) and Income Tax (a direct tax). Filing an LUT addresses only GST compliance.

• GST Compliance (via LUT): An LUT allows a service provider to export services without levying IGST on the invoice. It is a procedural compliance under GST law to facilitate tax-free exports.
• Income Tax Compliance: The revenue generated from these exports is still income and is fully taxable under the Income Tax Act, 1961. All freelancers and SaaS businesses must report their export earnings in their annual income tax returns and pay the applicable income tax on their net profits.

The LUT simplifies the indirect tax process but has no bearing on the direct tax liability. Proper accounting must be maintained to distinguish between GST obligations and income tax calculations.

3. FEMA & Export Compliance

Filing an LUT is not merely a tax formality; it is intrinsically linked to foreign exchange regulations governed by the Foreign Exchange Management Act, 1999 (FEMA).

A key condition undertaken in the LUT declaration (Form GST RFD-11) is the timely realization of export proceeds. According to Rule 96A of the CGST Rules, the payment for the exported services must be received in convertible foreign exchange within one year from the date of the export invoice.

Consequences of Non-Compliance:

• If the export proceeds are not realized within the stipulated timeline, the exporter is obligated to pay the IGST that was exempted, along with interest at 18% per annum, within 15 days of the expiry of the one-year period.
• Failure to do so can lead to the withdrawal of the LUT facility, forcing the business to pay IGST on all subsequent exports and then claim refunds.

Therefore, SaaS founders and freelancers must implement robust invoicing and payment tracking systems to ensure all foreign remittances are received and documented (e.g., via Foreign Inward Remittance Certificates - FIRC) within the legal timeframe.

4. Business Structuring Impact

The choice of business structure has direct implications for GST registration and LUT filing.

Regardless of the structure, GST registration is mandatory for any entity engaged in the inter-state supply of services, which includes all exports, even if the turnover is below the standard threshold limit.

5. Final Checklist for Founders (FY 2026-27)

This checklist outlines the steps to file Form GST RFD-11 for the Financial Year 2026-27. The GST portal enables this filing well in advance, and it should be completed before April 1, 2026.

• Navigate to LUT Section: Go to Services > User Services > Furnish Letter of Undertaking (LUT).
• Select Financial Year: From the drop-down menu, select 2026-27.
• Upload Previous LUT (If applicable): If you filed a manual LUT previously, you can upload a PDF/JPEG copy (max 2MB). For routine online renewals, this is not required.

• Update Invoicing: All export invoices issued from April 1, 2026, must include a declaration stating: "SUPPLY MEANT FOR EXPORT UNDER LETTER OF UNDERTAKING WITHOUT PAYMENT OF INTEGRATED TAX" along with the ARN.
• Track Payments: Diligently monitor the realization of export proceeds to comply with FEMA timelines.

💡 SaaS & Nomad Tip: Ensure your zero-rated exports and LUT filings are aligned with the Tax Year 2026 guidelines.
