Substance Over Form
The Tiger Global–Flipkart Decision and the Recalibration of India-Facing Investment Structures
The article then considers the implications for Singapore-based holding and fund structures. While Singapore remains structurally robust, the decision underscores that treaty access will increasingly depend on demonstrable commercial purpose, governance integrity and operational substance. Properly implemented Singapore platforms may continue to provide a defensible architecture for India-facing investments – but only where form and economic reality are credibly aligned.
A Watershed Supreme Court Ruling: Substance Over Form Prevails
The Indian Supreme Court’s judgment in Tiger Global–Flipkart represents a material recalibration of India’s treaty jurisprudence. The Court squarely confronted a question that has long animated cross-border structuring: whether formal treaty residence, supported by a valid tax residency certificate (TRC), is sufficient to secure treaty protection, or whether such entitlement remains contingent on demonstrable economic substance.
The Court’s answer was unequivocal: treaty entitlement is conditional on substantive commercial reality, and formal structuring alone will not suffice.
In this case, Tiger Global, a U.S. based fund, had routed its investment in Flipkart Singapore through Mauritius-based holding companies, a structure historically favored due to the India-Mauritius Double Tax Avoidance Agreement (DTAA). When Walmart acquired Flipkart Singapore in 2018, Tiger Global’s Mauritius entities sold their shares (in a Singapore holding company that owned Flipkart India) for a substantial gain. They asserted that, because the shares were acquired before 1 April 2017, the capital gains were exempt from Indian tax under the India-Mauritius DTAA’s grandfathering clause and backed by valid Mauritius Tax Residency Certificates (TRCs).
However, the Indian tax authorities challenged this claim, alleging the Mauritius entities were mere conduits or “see-through” shells with no real business presence. All key decisions and control, the authorities argued, actually rested with Tiger Global’s team in the U.S., indicating the structure’s lack of genuine commercial substance. The arrangement was deemed prima facie designed for tax avoidance, prompting the Authority for Advance Rulings (AAR) to refuse an advance ruling on the matter in 2020. Although the Delhi High Court later disagreed and upheld Tiger Global’s treaty claim (emphasising the sanctity of the TRC and the treaty’s grandfathering of pre-2017 investments), the Supreme Court ultimately overturned that decision. In January 2026, the Supreme Court held Tiger Global’s investment structure to be an “impermissible tax avoidance arrangement” put in place solely to obtain treaty benefits. Consequently, capital gains from the Flipkart Singapore stake sale were ruled taxable in India under domestic law, notwithstanding the DTAA. This outcome has effectively re-anchored the principle that tax treaty benefits are conditional, not automatic, and must reflect a real economic presence in the jurisdiction of residence.
Of particular significance is the Court’s confirmation that India’s GAAR may operate alongside – and, where abuse is established, effectively override – treaty protections. The judgment makes clear that grandfathering protection is not self-executing; rather, it remains contingent on the underlying arrangement being commercially bona fide. Where the tax benefit is realised post-GAAR implementation, legacy entry dates alone will not insulate the structure from challenge.
Crucial findings of the Supreme Court underscore this shift toward substance-over-form. First, the Court stated that treaty benefits are not a mechanical entitlement, if the factual review shows an arrangement aimed chiefly at avoiding tax, any treaty exemption “automatically fails”. Double tax treaties, the judges noted, exist to prevent genuine double taxation, not to facilitate deliberate tax avoidance. Second, a TRC is not conclusive proof of eligibility. Possessing a TRC is merely an “eligibility condition” for seeking treaty relief, not a guarantee. Indian authorities are entitled to look behind the TRC and examine whether the entity has commercial substance in its home country; if not, they can lift the corporate veil and deny benefits. This is a clear departure from earlier jurisprudence (e.g. Azadi Bachao Andolan in 2003) which had treated TRCs as near-sacrosanct evidence of residence. Third, the Court confirmed that India’s General Anti-Avoidance Rule (GAAR) can override tax treaty provisions in cases of abuse. GAAR, implemented from 2017, empowers authorities to ignore or recharacterise transactions that lack commercial purpose apart from tax avoidance. The ruling clarified that even investments made before GAAR’s start date (such as Tiger Global’s pre-2017 shares) are not immune if the tax benefit (sale) occurred after GAAR’s introduction. In other words, treaty grandfathering is not absolute, it protects only “genuine investments, not abusive arrangements”. If a structure is found to be a sham or conduit, the fact that the investment was made pre-2017 will not save it from GAAR-based scrutiny. Finally, the Supreme Court stressed India’s tax sovereignty, noting that taxing income arising from Indian assets is an inherent right that cannot be contracted away by abuse of treaties.
Taken together, the Tiger Global-Flipkart judgment signals a paradigm shift: economic reality must align with legal form when claiming treaty relief. The long-standing comfort that a valid foreign incorporation and TRC alone suffice for treaty benefits has been upended. Now, substance is king. This new stance has profound implications for cross-border investors, especially those using traditional “tax haven” conduits.
Risks of Weak-Substance Jurisdictions: The Mauritius Lesson
The decision materially elevates the risk profile of traditional low-substance intermediary jurisdictions. Mauritius, historically the dominant conduit for India-bound capital, is the most immediate casualty, but the Court’s reasoning is clearly portable across jurisdictions exhibiting similar “substance-light” characteristics.
By emphatically denying Tiger Global the Mauritius treaty exemption, the Supreme Court has put investors on notice about the risks of using jurisdictions with weak substance. Mauritius, in particular, has long been a popular intermediary for India-bound investments (at one point channeling the largest share of foreign direct investment (FDI) into India) due to its favorable DTAA which historically exempted capital gains. Many Mauritius entities, however, were little more than P.O. boxes with minimal operations, set up solely to “treaty shop” – i.e., obtain tax benefits not available to the investor’s home country. The Tiger Global structure was a case in point: the Mauritius companies had no other investments or business beyond holding Flipkart shares, and even their bank accounts were effectively controlled by the U.S. parent’s fund managers. The Supreme Court (echoing the earlier AAR findings) saw through this, characterising the entities as “merely front or conduit companies” with real management in the U.S. In such a scenario, treaty benefits were perhaps rightfully denied, a clear warning that shell companies in low-substance jurisdictions are vulnerable.
Notably, the ruling comes after significant changes had already been made to treaties like the India-Mauritius DTAA. In 2016, India and Mauritius agreed to amend their treaty to tax capital gains on shares acquired from 2017 onwards (ending a decades-long exemption), while grandfathering prior investments. Even Limitation of Benefits (LOB) clauses and GAAR provisions were introduced to curb treaty abuse, requiring a certain level of commercial activity for an entity to qualify for treaty relief. The Tiger Global-Flipkart case effectively tested these anti-avoidance measures. The Court’s message is that simply meeting formal LOB criteria or holding a TRC may not suffice if the overall arrangement is artificial. For example, Tiger Global’s claim of treaty grandfathering was rejected because the structure itself was not bona fide, the Court held that grandfathering “can only be claimed if the investments were genuine and did not arise from arrangements that lacked substance”. In substance, anti-abuse considerations are likely to override the strict letter of the law in cases of conflict.
This has broader implications for other traditionally low-substance hubs beyond Mauritius. Jurisdictions like Cyprus or the Cayman Islands, or routing through entities that exist solely on paper, now carry heightened tax risk for India-focused investors. As such, the private equity exits and FPI investments similar jurisdictions are all in the spotlight, especially for legacy structures where substance could be questioned. In essence, any arrangement that relies on form alone, a mailing address and a brass plate, is on thin ice. Tax authorities are emboldened to “examine the commercial substance of overseas investment structures” and will not hesitate to deny treaty benefits where that substance is lacking. The era when an investor could flash a residency certificate from a zero-tax locale and automatically escape Indian tax is over.
The writing on the wall is clear: structures that smack of treaty shopping or have “substance-lite” footprints now carry substantial uncertainty. Relying solely on past court precedents that respected legal form (or on the notion that India welcomes inbound investment at any cost) is no longer safe. The Supreme Court has shifted the balance decisively in favor of anti-avoidance. Going forward, cross-border investments into India must be structured with robust substance in mind to withstand potential GAAR challenges and judicial scrutiny.
For private equity sponsors, the decision is particularly consequential at the exit stage. Structures that appeared defensible at entry, especially pre-2017 legacy platforms, may now face renewed scrutiny upon monetisation events. Fund managers should assume that Indian revenue authorities will increasingly focus on exit-driven GAAR analysis, with particular attention to board control, investment committee location, and value-creation functions.
Implications for Singapore Transactions
The practical implication is clear: Singapore SPVs will no longer benefit from any presumption of treaty robustness. Indian authorities are likely to apply a fact-intensive substance inquiry similar to that deployed in Tiger Global–Flipkart, particularly where the Singapore entity functions primarily as an intermediate holding vehicle.
Under India’s reformed legal regime, a Singapore special purpose vehicle (even with a TRC and formal board) could be treated like the Mauritius vehicles in Tiger Global-Flipkart ruling if its substance is inadequate. Indeed, an Indian tribunal (the Delhi ITAT) recently denied treaty benefits to a Singapore company in Hareon Solar Singapore where it found no commercial purpose or substance in the Singapore entity. In that case, the company’s annual expenses (just professional fees) far exceeded SGD200,000 (the LOB “Expenditure Test”), yet the tribunal concluded the entity was a mere “shell or conduit” incorporated solely for tax purposes. This illustrates that even Singapore-incorporated companies must meet the treaty’s economic substance requirements.
Conversely, Singapore structures with demonstrable substance are still likely to receive relief. In Fullerton Financial Holdings (involving Temasek Group’s investment in India), a Mumbai Tribunal allowed the capital gains exemption for grandfathered shares because it found that the Singapore company had “adequate commercial substance” and incurred genuine operational expenses in Singapore. The tribunal specifically noted that the Singapore taxpayer was not a conduit and that obtaining treaty benefits was not one of the principal purposes of the transaction. Crucially, India’s updated India-Singapore tax treaty (via the OECD Multilateral Instrument) contains an anti-abuse Principal Purpose Test (PPT) and Limitation-of-Benefits (LOB) clause. These provisions deny treaty benefits if one of the “principal purposes” of an arrangement is to secure tax advantages. A company is deemed a shell or conduit if it has “negligible or no genuine business operations”, specifically – if annual spend is below SGD 200,000. Thus, Singapore-based investors must be prepared to show that their structures serve bona fide business objectives (such as risk management, financing or other strategic functions), not merely tax avoidance.
In practical terms, Singapore practitioners should counsel clients to bolster any Singapore holding company with real substance. This can include appointing resident directors who meaningfully participate in governance, keeping minutes of board meetings held in Singapore, maintaining local office space or employees, and ensuring that any expenses charged to the entity (for services, staff or overheads) are genuine and documented. Singapore corporate law already requires a resident director and annual statutory filings, which can support a substantive presence but merely satisfying these technical requirements may not be enough under India’s scrutiny. Given that GAAR can override treaty benefits even for older deals, advisers should revisit existing Singapore-India structures and consider whether additional documentation or corporate reforms are needed. As such, Investors should proactively review and strengthen governance, board independence, decision-making processes and operational substance in treaty jurisdictions, reliance on a TRC or historical exemptions is no longer sufficient.
On the tax side, Singapore has no capital gains tax, but its role in India deals has primarily been as a conduit to obtain treaty relief on Indian gains. Following the 2017 amendment to the India-Singapore DTAA, capital gains from the sale of Indian shares (acquired after 2017) may be taxed in India (subject to grandfathering for earlier share purchases). Crucially, India retained the right to apply its domestic anti-avoidance rules even if the treaty is otherwise beneficial. Singapore lawyers should therefore not assume that treaty updates guarantee relief: under current law, any Singapore structure will be examined on its merits.
Advisors in Singapore may also need to think about economic substance requirements. Singapore does not impose a general anti-avoidance regime on investors, but it has enhanced its own substance regulations for certain sectors (e.g. finance and intellectual property holding companies). More broadly, Singapore’s transparent corporate registry and mandatory audit requirements can work in an investor’s favor (by evidencing substance), but they also mean that India’s authorities can access company details if they pursue an inquiry. In sum, Singapore counsel must now integrate the Tiger Global-Flipkart principles into their advice: emphasising commercial justification, robust governance, and thorough documentation, especially where clients seek to leverage Singapore’s treaty network or corporate vehicle for India-related deals.
Demonstrating Substance in Singapore: Key Best Practices
Singapore’s appeal as an investment hub is well-recognised. The city-state offers political and economic stability, a strong rule-of-law environment, highly developed financial markets and an extensive network of double tax treaties (including with India) that can facilitate cross-border capital flows. Singapore allows 100% foreign ownership and imposes no capital gains tax, which can make it an efficient holding location for many Asia-Pacific deals. Its corporate and banking regulations encourage transparency and compliance and Singapore’s courts are respected for enforcing contracts and protecting investor rights. These attributes, along with Singapore’s strategic time zone and connectivity to the region, underlie its reputation as a logical base for managing investments into India and elsewhere.
However, these strengths must be balanced against the need to meet India’s substance standards case by case. No jurisdiction’s legal protections override the substance test: simply incorporating in Singapore is not a guarantee of favorable tax treatment in India. The Tiger Global-Flipkart ruling, together with recent Indian tribunal decisions, makes clear that Indian tax authorities will evaluate Singapore structures on their commercial reality. For instance, the Hareon Solar tribunal explicitly called out the lack of economic purpose in the Singapore entity, despite formal compliance. On the other hand, the Fullerton/Temasek case shows that Singapore entities with genuine activity can successfully claim treaty benefits.
Crucially, the PPT and LOB provisions under the India-Singapore DTAA stipulate that treaty relief on capital gains may be denied where obtaining such relief is found to be one of the “principal purposes” of the arrangement. Also, a Singapore company is excluded if it is a “shell or conduit” as defined by the treaty (e.g. failing the SGD 200,000 expenditure test). Thus, Singapore’s role as a treaty conduit is expressly limited by the treaty language itself. Singapore counsel should advise clients that any Singapore structure must be set up with these treaty requirements in mind. This means not only meeting the formal conditions (like filing an Indian TRC or satisfying the expenditure test) but ensuring that the Singapore entity has a substantive business reason, such as real financing needs, risk segmentation or operational support, beyond just tax.
It is appropriate to acknowledge Singapore’s advantages in finance and corporate law, but the analysis must emphasise that each deal turns on its facts. For example, if a client argues that Singapore’s robust regulatory framework should immunize a structure, the adviser should caution that Indian courts will focus on the actual arrangements, not just the clean statutory environment of Singapore. Singapore itself has no special extraterritorial tax immunity clause; India’s GAAR can be applied even if its application is not beneficial. In other words, India explicitly reserves the right to override treaty benefits regardless of the partner country’s perceived friendliness.
At the same time, Singapore’s established governance mechanisms can help demonstrate substance. A well-managed Singapore holding company typically maintains minutes, board resolutions and audited financial statements, all of which can be shown to support its independent activities. Legal advisers can highlight these aspects to bolster a treaty claim. But they must also stress potential risks: any indication that decisions were driven by offshore groups or that funds were round-tripped through Singapore with no real investment purpose would undermine the structure’s integrity. In short, the Singapore jurisdiction offers a high-quality framework, but this advantage is only meaningful when the Singapore entity is genuinely operating as a real enterprise.
Practical Risk Mitigation Steps for Singapore-Based Structures
Based on the Tiger Global-Flipkart outcome, Singapore lawyers should update their standard advice on India-facing transactions. Key changes include:
- Board Control: Ensure that strategic decision-making demonstrably occurs in Singapore, supported by contemporaneous board minutes, resident director participation and evidence of independent deliberation.
- Documentation Discipline: Maintain defensible evidentiary records, including service agreements, intra-group cost allocations, and functional analyses supporting the Singapore entity’s commercial role.
Commercial Narrative: Contemporaneously document the non-tax drivers for the Singapore platform (e.g., regional treasury management, investor aggregation, regulatory positioning), recognising that post-hoc justifications carry limited evidentiary weight.
- Tax Treaty Strategy: For share sales of Indian targets, note that pre-2017 acquisitions enjoy grandfathering only if proper conditions are met, and post-2017 deals will likely be taxed by India. Evaluate whether the Singapore vehicle still offers benefits, or if alternative routes (e.g. direct investment or via jurisdictions with existing BIT protections) might be preferable.
- Anticipate Indian Audit: Advise clients that Indian tax authorities may request information about Singapore entities (including TRCs, audited accounts and board minutes). Prepare answers in advance, demonstrating substance in Singapore.
- Cross-Border Compliance: Ensure that any Singapore structure complies not only with Singapore law but also with Indian regulatory regimes (e.g. foreign investment rules under India’s exchange control regime), since non-compliance could trigger additional scrutiny or penalties.
The Tiger Global–Flipkart decision does not diminish Singapore’s continued relevance as an investment hub. However, it decisively ends the era in which treaty access could be engineered primarily through formal structuring. For sponsors and advisers alike, the new discipline is clear: substance must now be designed, documented and continuously maintained. In the post-GAAR environment, defensibility is no longer a function of jurisdictional selection alone, but of sustained operational credibility.
