Tiger Global & the 2026 Amendments: The Grandfathering Relief That Doesn’t Forgive Thin Structures

Introduction: A Swift Legislative Response to a Transformative Judgment

The Supreme Court’s decision in Authority for Advance Rulings v. Tiger Global International Holdings marked a decisive shift in India’s international tax landscape, particularly in its treatment of treaty entitlement, indirect transfers, and the threshold application of anti-avoidance principles. The ruling expanded the scope of scrutiny at the advance ruling stage and introduced a degree of uncertainty for legacy investment structures especially those routed through Mauritius prior to 1 April 2017.

In a calibrated response, the Government, through amendments to Rules 10U and 128 of the Income-tax Rules (31 March 2026), has sought to restore certainty by clarifying that GAAR shall not apply to income arising from transfer of investments made prior to 1 April 2017. While this intervention partially mitigates the immediate impact of the judgment, it does not dilute the broader doctrinal shift. Instead, it creates a layered regime where grandfathering is preserved, but anti-avoidance scrutiny continues through parallel routes.

The Notifications: What Has Actually Changed

The amendments explicitly carve out an exception from GAAR for income arising from transfer of investments made prior to 1 April 2017. This restoration provides:

• Temporal certainty for legacy investors
• Alignment with the original intent of the India–Mauritius treaty protocol (2016)
• Protection against retrospective anti-avoidance application

Funds holding pre-2017 India exposure can therefore assert greater confidence in exit tax positions and resist GAAR-based denial of treaty benefits for such investments.

However, this relief is targeted, not systemic.

The amendments address the specific GAAR concern, they do not reverse the Supreme Court’s broader doctrinal conclusions on substance, treaty entitlement, and AAR jurisdiction.

What the Notifications Do Not Change

1. Expanded AAR Scrutiny Remains: The Supreme Court’s endorsement of a wide “prima facie” inquiry at the AAR stage continues to apply. Authorities may examine the entire transaction lifecycle, control and management patterns, and exit structuring. This significantly reduces the utility of AAR for complex cross-border exits.

2. Treaty Entitlement Is Still Rebuttable: The judgment weakens the conclusiveness of Tax Residency Certificates (TRCs). Treaty protection is now conditional and subject to substance-based review. A TRC is necessary but no longer sufficient.

3. Indirect Transfer Exposure Continues: The distinction between direct share transfers (protected) and indirect transfers of foreign companies deriving substantial value from India remains intact. This is arguably the most commercially significant risk in the post-Tiger Global landscape.

GAAR Is Out But Anti-Avoidance Is Not

The removal of GAAR for pre-2017 investments does not eliminate anti-avoidance scrutiny. Instead, such scrutiny now operates through:

• AAR jurisdictional filters
• Judicial anti-abuse principles
• Treaty interpretation standards (including PPT-like reasoning)

The net effect is a structural shift: Formal GAAR invocation → Embedded anti-avoidance mindset

The question is no longer whether GAAR applies, it’s whether the structure demonstrates genuine substance and commercial rationale.

Structuring Cross-Border Investments Post – Tiger Global: Key Consideration

The most important takeaway for investors is this: substance is no longer a defensive argument but a structural requirement. Going forward, cross-border investments involving India should be designed with the following considerations in mind.

1. Align Legal Structure with Real Decision-Making: Board meetings must be genuinely conducted in the claimed jurisdiction. Key strategic decisions should originate where residence is claimed. Avoid concentration of decision-making power in another jurisdiction such as the sponsor’s home country. “Effective management” is now a trigger for treaty denial, even at a prima facie stage.

2. Avoid Single-Asset Holding Structures Without Commercial Justification

Structures that hold only one Indian asset and exist solely for investment and exit are more vulnerable to “pre-ordained arrangement” allegations and treaty abuse arguments. The mitigation is to demonstrate a genuine portfolio strategy not just tax routing.

3. Build Contemporaneous Commercial Rationale: Every structuring decision should be supported by investment memos, jurisdiction selection rationale, and regulatory or investor-driven considerations. Courts increasingly test intent at inception, not post-facto explanations.

4. Re-evaluate Use of Intermediate Holding Companies: Where using Mauritius, Singapore, Netherlands, or similar jurisdictions, ensure real economic presence and functional substance including board, employees, and decision-making. Without this, such entities risk being treated as conduits rather than genuine investors.

5. Carefully Assess Indirect Transfer Exposure: Even if shares are sold offshore, they may still be taxable in India if value is substantially derived from Indian assets. Conduct a value attribution analysis upfront, evaluate treaty coverage for indirect transfers, and consider alternative exit routes where feasible.

6. Do Not Over-Rely on TRC: A Tax Residency Certificate is necessary but no longer sufficient. Substance, control, and commercial purpose must support it. Investors that rely solely on TRC as a shield are now exposed to heightened scrutiny at every stage of adjudication.

7. Reconsider Advance Ruling Strategy: Post-Tiger Global, AAR is no longer a “safe harbour.” Complex structures may be better handled through assessment-stage litigation or advance planning with withholding positions. Seeking an AAR ruling on a structure with thin substance may now produce an adverse prima facie determination.

8. Integrate Tax with Governance and Compliance: Tax structuring must now align with legal governance, board oversight, and internal documentation. This is no longer purely a tax exercise—it is a governance issue that touches board composition, decision records, and entity management protocols.

Practical Implications for Investors

Legacy Investments (Pre-2017): Partial Relief: Pre-2017 investments benefit from GAAR exclusion and improved certainty on exit tax positions. However, the widened AAR scrutiny and weakened TRC conclusiveness still apply to these structures. Investors should not assume complete immunity from challenge on other anti-avoidance grounds.

New Investments (Post-2017): Higher Scrutiny Baseline: Post-2017 structures must assume full-spectrum anti-avoidance review from the outset. Every layer of the investment vehicle from the fund domicile to the holding company to the exit mechanism will be examined for substance and commercial purpose.

Exit Planning Is Now a Tax Outcome Driver: Tax outcomes will increasingly depend on how exits are structured and whether indirect transfer exposure is identified and mitigated early. Deal teams should integrate tax counsel at the term-sheet stage rather than as a post-signing exercise.

Conclusion: A New Equilibrium Between Certainty and Scrutiny

The Government’s 2026 amendments restore an important layer of certainty for legacy investors, but they do not reverse the fundamental shift introduced by the Supreme Court in Tiger Global. The ruling embeds anti-avoidance considerations into the very entry point of tax adjudication and weakens the traditional reliance on form-based treaty claims.

For investors, the message is clear: 

Structural integrity, commercial rationale, and jurisdictional substance are now central to tax outcomes not peripheral considerations. The future of cross-border investment into India will be defined not merely by treaty provisions, but by the ability to demonstrate that form, substance, and intent are aligned from day one.
