GST LUT for SaaS Exports 2026: A Guide to the New Direct Tax Code

Quick Answer

A professional compliance guide for SaaS Founders and Digital Nomads on filing the GST LUT for FY 2026-27 amid the transition to the new Income Tax Act 2025.

Key Takeaways

  • Mandatory GST LUT for 2026-27: To export software subscriptions without paying IGST upfront, SaaS founders and digital nomads must file a Letter of Undertaking (LUT) for the financial year 2026-27. The deadline for this is March 31, 2026.
  • New Direct Tax Law Effective April 1, 2026: The Income Tax Act, 1961, is being replaced by the new, simplified Income Tax Act, 2025. This new law will be effective from April 1, 2026, and will govern all direct tax matters from FY 2026-27 onwards.
  • Separate Compliance Streams: The transition to the new Direct Tax Code does not change the Goods and Services Tax (GST) framework. GST compliance, including the filing of an LUT for exports, remains a separate and parallel requirement.
  • FEMA Simplification: Recent amendments to the Foreign Exchange Management Act (FEMA) in 2026 have simplified reporting for service exporters, allowing for consolidated monthly declarations, which is highly beneficial for high-volume SaaS businesses.

PART 1: EXECUTIVE SUMMARY

This guide provides a detailed compliance roadmap for SaaS founders and Digital Nomads navigating the significant tax changes effective in 2026. The Indian tax landscape is undergoing a foundational shift with the replacement of a six-decade-old direct tax law. Our analysis focuses on the practical implications for exporting digital services.

  • The Old Law (1961): The Income Tax Act, 1961, has been the bedrock of India's direct tax system. Characterised by numerous amendments, its complexity often created compliance challenges. For exporters, while the income tax provisions governed profits, GST laws separately managed the tax treatment of exports. Under the GST regime, exporters could ship services without upfront tax payment by filing an annual LUT.

  • The New Law (2025): The Income Tax Act, 2025 (also referred to as the Direct Tax Code), will be implemented on April 1, 2026. Its primary objective is to simplify, streamline, and modernise the direct tax structure, making compliance more straightforward. A key change is the introduction of a single 'Tax Year' concept, replacing the confusing 'Previous Year' and 'Assessment Year' terminology. It is critical to understand that this new act overhauls direct taxes (income tax) and does not directly amend the indirect tax (GST) laws that govern LUT filings.

  • Who is Impacted: This transition directly impacts all taxpayers in India. For SaaS founders and digital nomads earning in foreign currency, the impact is twofold. They must align their business accounting and profit calculation with the new Income Tax Act, 2025, from April 2026. Simultaneously, they must continue to adhere to the established GST framework for exports, where the timely filing of the LUT for FY 2026-27 is a non-negotiable compliance task to maintain healthy cash flow.


PART 2: DETAILED TAX ANALYSIS

1. Tax Landscape for SaaS & Digital Nomads

The tax environment for technology-focused exporters like SaaS companies and digital nomads is governed by multiple statutes. The primary pillars are Direct Tax law (for income), GST law (for the supply of services), and FEMA (for foreign exchange).

Direct Taxation: The Shift to the Income Tax Act, 2025

Effective April 1, 2026, the new Income Tax Act, 2025, will replace the 1961 Act. For SaaS businesses and professionals, this means re-evaluating tax planning strategies.

  • Presumptive Taxation: Schemes like Section 44ADA, which allow professionals with receipts up to ₹50 lakhs to declare 50% of their income as profit, are expected to continue in a similar form, offering a simplified compliance route for many digital nomads. It is crucial to monitor the final text of the new Act for specific clauses.
  • Business Expenses: For those not under presumptive schemes (typically incorporated SaaS entities or freelancers with higher turnover), the definition and eligibility of deductible business expenses (e.g., server costs, software subscriptions, marketing spend) will be governed by the new Act's simplified provisions.
  • Residency Rules: A digital nomad's tax liability in India is determined by their residential status. The new Direct Tax Code aims to bring more clarity to these rules, which is crucial for individuals who split their time between India and other countries.

Indirect Taxation: GST on Software Exports

The export of software and SaaS is classified as a "zero-rated supply" under the IGST Act. This is a significant advantage, but it is not automatic. To benefit, specific conditions must be met:

  1. The supplier of service is located in India.
  2. The recipient of service is located outside India.
  3. The place of supply of service is outside India.
  4. Payment for the service is received in convertible foreign exchange.
  5. The supplier and recipient are not merely establishments of the same person.
AspectCompliance RequirementImplication for SaaS Founders
GST Rate on ExportsZero-Rated (0%)No GST is charged on invoices to foreign clients. This makes pricing globally competitive.

Consequence of Non-FilingPay IGST and Claim RefundWithout a valid LUT, the exporter must first pay 18% IGST on the export invoice and then proceed to claim a refund, which severely impacts working capital.
Input Tax Credit (ITC)RefundableExporters can claim a refund of the GST paid on their business inputs (e.g., GST on office rent, professional fees, domestic software purchases). This reduces the cost of operations.

2. Direct Tax vs GST Interplay

It is a common misconception that a change in income tax law will affect GST procedures. These are two distinct taxation systems.

  • Income Tax Act, 2025: Deals with tax on profits. The revenue you receive from a US client is part of your gross turnover. After deducting eligible business expenses, the resulting net profit is taxed according to the slabs in the new Direct Tax Code.
  • GST Act: Deals with tax on the transaction of supply. The act of providing a software subscription to a US client is the taxable event. Because it's an export, this transaction is zero-rated, provided you have filed the LUT.

The transition to the new direct tax law has no bearing on your requirement to file a GST LUT. The LUT is a procedural requirement under GST to enable the zero-rating of your export transactions. Whether your profits are taxed under the 1961 Act or the 2025 Act, your export invoices must be handled according to GST rules.

3. FEMA & Export Compliance

The Foreign Exchange Management Act, 1999 (FEMA) governs all foreign currency transactions. For SaaS exporters, this is a critical layer of compliance.

  • Realisation of Export Proceeds: Exporters are required to receive their foreign payments within a specified timeline (recently extended from 9 to 15 months) to qualify for export benefits.
  • Reporting: Every inward remittance must be correctly reported to the Authorised Dealer (AD) bank. The bank will issue a Foreign Inward Remittance Certificate (FIRC) as proof of the export earning.
  • Simplified Reporting under New Regulations (2026): Acknowledging the nature of the digital economy, new FEMA regulations introduced in early 2026 provide significant relief. Service exporters can now file a single consolidated declaration for all services rendered in a calendar month, which is a major departure from older, invoice-wise reporting requirements. This is a huge efficiency gain for SaaS models with hundreds or thousands of monthly subscriptions.

4. Business Structuring Impact

The choice of business structure has direct implications under both tax regimes.

  • Sole Proprietorship/Freelancer: This is the simplest structure, often used by digital nomads.
    • Direct Tax: Profits are taxed at individual slab rates under the new Income Tax Act, 2025. The option of presumptive taxation under Section 44ADA may be available.
    • GST: GST registration is mandatory if turnover exceeds ₹20 lakhs. LUT filing is required for exports.
  • Limited Liability Partnership (LLP) / Private Limited Company: These structures are preferred by growing SaaS startups seeking liability protection and funding.
    • Direct Tax: The new Direct Tax Code proposes more stable and potentially uniform corporate tax rates, simplifying tax calculation for these entities.
    • GST: Compliance is more formal. The process for LUT filing remains the same, but documentation and record-keeping are subject to greater scrutiny.

5. Final Checklist for Founders

To ensure a smooth transition and full compliance in Tax Year 2026, founders should take the following steps:

  • [ ] File GST LUT for FY 2026-27: Log in to the GST portal and file Form GST RFD-11 before March 31, 2026. This is the highest priority action for maintaining export benefits.
  • [ ] Review Accounting Systems: Instruct your accounting team to prepare for the transition to the Income Tax Act, 2025. This includes understanding the new definitions, expense classifications, and the 'Tax Year' concept.
  • [ ] Update Invoicing for FY 2026-27: Ensure your invoices for foreign clients from April 1, 2026, correctly state "Supply meant for Export under Letter of Undertaking without payment of IGST" and include your LUT Application Reference Number (ARN).
  • [ ] Consolidate FEMA Reporting: Liaise with your AD bank to adopt the new consolidated monthly reporting mechanism for export remittances to reduce administrative overhead.
  • [ ] Check GST Registration Threshold: If you are a digital nomad currently below the ₹20 lakh turnover limit, monitor your revenue closely. Crossing this threshold will trigger a mandatory GST registration requirement.
  • [ ] Maintain Documentation: Keep meticulous records of all foreign client contracts, invoices, and bank remittance advice (FIRCs). This is essential for both GST (for ITC refunds) and Income Tax assessments.

Frequently Asked Questions

Do I need to file a GST LUT for my SaaS export business in 2026?

Yes. To export software services without paying 18% IGST upfront, you must file a Letter of Undertaking (LUT) for the financial year 2026-27. The deadline is March 31, 2026.

How does the new Direct Tax Code 2025 affect my GST compliance?

The new Direct Tax Code (or Income Tax Act, 2025) replaces the old Income Tax Act, 1961, and governs your income tax on profits. It does not change the rules for GST, which is an indirect tax. Your requirement to file a GST LUT for exports remains unchanged.

If you export services after March 31, 2026, without a valid LUT for FY 2026-27, you will be required to pay IGST (currently 18%) on your export invoices and then claim a refund. This can block your working capital for several months.
