SaaS LUT Filing 2026: IGST Section 16 & Direct Tax Code Guide

Key Takeaways

• Zero-Rated Exports Unchanged: Section 16 of the IGST Act, which allows for the zero-rating of exports, is part of the Goods and Services Tax (GST) framework. This indirect tax law is separate from the Income Tax Act, 1961, and will not be directly amended by the proposed Direct Tax Code (DTC) 2025.
• LUT Filing is Critical: For SaaS and service exporters, filing a Letter of Undertaking (LUT) via Form GST RFD-11 remains a critical annual compliance task. Filing the LUT allows businesses to export services without the upfront payment of IGST, significantly preserving working capital and avoiding complex refund procedures. The LUT must be renewed each financial year.
• Direct Tax Code's Potential Impact: While the DTC will not alter GST law, its proposed changes—such as simplified corporate tax slabs and potentially phasing out specific export-linked deductions—will reshape the overall profitability and tax strategy for digital exporters. The focus may shift from specific exemptions to a regime of lower, broader tax rates.
• FEMA and Business Structure are Key: Compliance with the Foreign Exchange Management Act (FEMA), including timely realization of export proceeds, is intrinsically linked to GST benefits. Furthermore, the choice of business structure (e.g., Private Limited Company vs. LLP) has profound implications for both tax efficiency and the ability to attract foreign investment.

PART 1: EXECUTIVE SUMMARY

This guide provides a detailed compliance framework for SaaS founders and digital nomads on navigating the tax landscape in 2026, with a specific focus on zero-rated exports under GST and the anticipated environment under the new Direct Tax Code, 2025.

• The Old Law (Income Tax Act, 1961 & GST Act, 2017): Under the current dual system, SaaS exporters manage direct and indirect taxes separately. For direct taxes, the Income Tax Act, 1961, provided certain deductions and benefits for export-oriented units, though many have been phased out. For indirect taxes, Section 16 of the IGST Act, 2017, defines exports as "zero-rated supplies," allowing SaaS companies to export services without levying IGST, provided they file an annual Letter of Undertaking (LUT). This mechanism prevents the blocking of working capital that would otherwise be paid as tax and later claimed as a refund.

• The New Law (Direct Tax Code, 2025 & Existing GST): It is crucial to understand that the proposed Direct Tax Code (DTC) 2025 is designed to replace the Income Tax Act, 1961, not the GST laws. Therefore, the core mechanism of Section 16 of the IGST Act and the requirement for LUT filing will continue unchanged. The primary change under the DTC will be in the realm of corporate and personal income tax. The DTC aims to simplify tax law by reducing exemptions, widening tax slabs, and potentially introducing a flat corporate tax rate, thereby shifting the tax incentive structure for all businesses, including exporters.

• Who is Impacted: This guide is essential for all Indian-domiciled SaaS companies, service exporters, and digital nomads who serve international clients. Founders and finance teams must understand that while their GST compliance for exports (i.e., LUT filing) remains consistent, their long-term financial and tax strategies must adapt to the new direct tax environment proposed by the DTC. The interplay between GST, the new DTC, and FEMA regulations will define the compliance and profitability landscape for the foreseeable future.

PART 2: DETAILED TAX ANALYSIS

1. Tax Landscape for SaaS & Digital Nomads

The tax environment for India's burgeoning SaaS and digital nomad sector is governed by a confluence of direct taxes, indirect taxes, and foreign exchange regulations. Understanding the distinct roles of each is fundamental to maintaining compliance and optimizing financial strategy.

GST Compliance: The Bedrock of SaaS Exports

The cornerstone of the export regime for SaaS is Section 16 of the IGST Act, 2017, which classifies the export of services as a "zero-rated supply." This status is highly advantageous and distinct from "exempt supplies." While both are taxed at 0%, a zero-rated supply allows the exporter to claim a refund of the Input Tax Credit (ITC) paid on inputs (e.g., software licenses, cloud hosting, marketing services). This ensures that domestic taxes are not exported, keeping Indian SaaS offerings globally competitive.

To operationalize this benefit, a SaaS exporter has two procedural options:

1. Export with payment of IGST and claim a refund: This route involves paying the applicable IGST on the export invoice and then undergoing a refund process. This is generally not preferred as it blocks significant working capital.
2. Export without payment of IGST under a Letter of Undertaking (LUT): This is the standard and most efficient method. By filing Form GST RFD-11 annually on the GST portal, an exporter undertakes to fulfill all export obligations. This allows the company to issue export invoices without charging IGST.

Key LUT Compliance Points:

• Annual Renewal: An LUT is valid for a single financial year (April-March). A fresh LUT must be filed for FY 2026-27, ideally before April 1, 2026, to ensure uninterrupted zero-rated exports.
• Eligibility: Nearly all registered exporters are eligible, except those prosecuted for tax evasion exceeding ₹2.5 Crore.
• Online Process: The filing is a straightforward online process on the GST portal, requiring basic business details and information for two independent witnesses.

2. Direct Tax vs GST Interplay

The proposed Direct Tax Code (DTC) 2025 seeks to replace the six-decade-old Income Tax Act, 1961. It will not directly affect the GST provisions of Section 16. However, its implementation will have a significant indirect effect on the financial planning of export businesses.

This shift means that while the operational benefit of zero-rated exports under GST continues, the ultimate profit retained by the company and its shareholders will be governed by the simpler, broader rules of the DTC.

3. FEMA & Export Compliance

Compliance with the Foreign Exchange Management Act, 1999 (FEMA) is a non-negotiable prerequisite for availing export benefits under GST. The two legal frameworks are interconnected.

Key FEMA Obligations for SaaS Exporters:

• Realization of Export Proceeds: Export proceeds must be received in convertible foreign currency within the timeline prescribed by the RBI (currently extended to 15 months from the invoice date). Failure to realize these proceeds can lead to the revocation of GST benefits. Specifically, if a refund of unutilized ITC has been claimed, it must be returned with interest if payment is not received within the FEMA timeline.
• Reporting and Documentation: SaaS exporters must ensure proper reporting of inward remittances to their Authorized Dealer (AD) bank. Recent regulatory changes in 2026 aim to simplify this by allowing for consolidated monthly filings instead of invoice-wise reporting, which is a significant relief for high-volume, low-value subscription businesses.
• Purpose Codes: It is vital to use the correct RBI purpose codes (e.g., P0802 for software consultancy, P0806 for information services) for all inward remittances to correctly classify the income as export earnings.

A lapse in FEMA compliance not only invites penalties from the RBI but can also disqualify an entity from the benefits of zero-rated supply under GST, creating a dual compliance risk.

4. Business Structuring Impact

The choice of legal structure is a foundational decision that impacts taxation, liability, and fundraising capacity. For SaaS businesses targeting global markets, the choice generally narrows down to two viable options in India.

Furthermore, global SaaS companies often adopt a parent-subsidiary structure (e.g., a US parent with an Indian subsidiary). Structuring these cross-border relationships requires careful planning around Transfer Pricing regulations to ensure that transactions between the entities are conducted at an "arm's length" price.

5. Final Checklist for Founders

To ensure full compliance and strategic readiness for the 2026 tax environment, SaaS founders should adhere to the following checklist:

• GST & LUT Compliance:

  • Verify GST registration is active.
  • File Form GST RFD-11 for the Financial Year 2026-27 before making the first export of the year. The practical deadline is March 31, 2026.
  • Ensure all export invoices correctly state "Supply meant for Export under LUT without payment of IGST."
  • Maintain meticulous records of Input Tax Credit on all business expenses.

• FEMA Compliance:

  • Confirm that an Importer-Exporter Code (IEC) has been obtained.
  • Implement a system to track inward remittances and ensure they are realized within the RBI's prescribed timeline.
  • Instruct your AD bank to use the correct Purpose Codes for all foreign currency receipts.
  • Work with your CA/CS to adopt the new monthly consolidated reporting framework for service exports.

• Direct Tax & Structural Readiness:

  • Review your business structure (Pvt. Ltd. vs. LLP) to ensure it aligns with your long-term goals for funding and scale.
  • If operating a cross-border structure, conduct a review of your Transfer Pricing policy with a qualified tax advisor.
  • Model the financial impact of the proposed DTC changes on your company's profitability. Stay updated on the final tax rates and provisions as they are enacted.
  • Maintain clean and organized financial statements, as they are the foundation for all tax and regulatory filings.

By proactively addressing these areas, SaaS founders and digital nomads can build a robust compliance foundation that supports sustainable global growth.
