When a Tax Certificate Is Not Enough: Supreme Court Denies Treaty Benefits to Tiger Global, Rules That Paper Residency Cannot Shield Tax Avoidance

Facts and Issue of the Case

To understand this case, it helps to start with a simple background. India has signed Double Taxation Avoidance Agreements (DTAAs) with many countries, including Mauritius. Under the older version of the India–Mauritius DTAA, a company that was a tax resident of Mauritius did not have to pay capital gains tax in India when it sold shares of an Indian company. This arrangement — popularly called the “Mauritius Route” — was widely used by foreign investors since the early 1980s to invest in India through Mauritius holding companies and later exit their investments without paying capital gains tax in either country.

Tiger Global is a large US-based investment fund. Between 2011 and 2015, three of its Mauritius-incorporated companies — Tiger Global International II, III, and IV Holdings — purchased shares in Flipkart Singapore Private Limited, a company registered in Singapore that owned and operated the Indian e-commerce giant Flipkart. Since Flipkart Singapore’s entire value came from its Indian operations, its shares were treated as “indirectly” representing Indian assets for tax purposes under Indian law.

In 2018, as part of Walmart’s massive USD 16 billion acquisition of Flipkart, Tiger Global’s Mauritius companies sold their Flipkart Singapore shares to a Luxembourg company called Fit Holdings S.A.R.L. Tiger Global reportedly earned capital gains of approximately USD 1.6 billion from this sale. It approached the Indian tax authorities for a “nil withholding” certificate, claiming that its gains were fully exempt from Indian tax under Article 13(4) of the India–Mauritius DTAA. Tiger Global’s argument was straightforward: its Mauritius companies held valid Tax Residency Certificates (TRCs) issued by the Mauritian government, and that should be sufficient to claim treaty benefits.

The Indian tax authorities refused the nil withholding certificate. Tiger Global then applied to the Authority for Advance Rulings (AAR) — a body that gives advance tax rulings to non-residents. The AAR also rejected Tiger Global’s application, holding that the entire structure was a device created primarily to avoid tax in India and that real control of the Mauritius companies resided not in Mauritius but in the USA with Mr. Charles P. Coleman, Tiger Global’s principal. Tiger Global challenged this before the Delhi High Court, which ruled in its favour in August 2024. The Indian tax authorities then appealed to the Supreme Court.

The central legal issue before the Supreme Court was: Can a foreign company claim capital gains tax exemption under the India–Mauritius DTAA simply by holding a Tax Residency Certificate (TRC) from Mauritius? Or can the Indian tax authorities look beyond the certificate to examine whether the company is a genuine Mauritius resident with real commercial operations there — and deny treaty benefits if it is merely a conduit company set up to route investments and avoid Indian tax?

Observations by the Court

The Supreme Court, in a detailed judgment authored by Justice R. Mahadevan, made several important observations that together signal a significant transformation in how India will assess treaty-based tax claims by foreign investors going forward.

The Court observed that Tiger Global’s three Mauritius companies had no real operations in Mauritius. Their only activity was holding shares in Flipkart Singapore. Their boards of directors were formally based in Mauritius, but the actual authority to operate bank accounts and make investment decisions above USD 2,50,000 was vested with Mr. Charles P. Coleman — a US resident who was also declared as the beneficial owner of the companies. No local person in Mauritius was authorised to sign cheques independently. The Court concluded that the “head and brain” of these companies was not in Mauritius at all, but in the United States.

On the question of the TRC, the Court made a crucial observation: a Tax Residency Certificate is merely an eligibility condition under Section 90(4) of the Income Tax Act — it is relevant and necessary, but it is not conclusive proof of treaty entitlement. The Court held that the old CBDT Circular No. 789 of 2000, which had earlier been interpreted as giving TRC holders conclusive protection, had been superseded by subsequent legislative amendments, particularly by the introduction of Section 90(2A) and Chapter X-A (GAAR) in the Income Tax Act. A TRC alone, therefore, cannot prevent the tax authorities from examining whether the entity is genuinely resident in Mauritius and whether the arrangement is designed to avoid tax.

The Court also addressed the question of GAAR’s applicability to investments made before 2017. Tiger Global had argued that since its investments were made before 1 April 2017 (the date GAAR came into effect), they should be protected under the “grandfathering” exemption. The Court disagreed. It noted that under Rule 10U(2) of the Income Tax Rules, GAAR is triggered by the date when a tax benefit arises — not the date of investment. Since Tiger Global’s capital gains arose in 2018, after GAAR’s effective date, GAAR was fully applicable regardless of when the original investment was made. The grandfathering protection did not save them.

Importantly, the Court also observed that GAAR, once applicable, overrides DTAA provisions by virtue of Section 90(2A) of the Income Tax Act. In other words, even if a treaty technically exempts certain gains from Indian tax, that exemption can be overridden if the arrangement constitutes an impermissible tax avoidance arrangement under Indian domestic law.

Law Applicable

The judgment rests on a careful analysis of several provisions of Indian tax law and the India–Mauritius DTAA. Understanding these legal provisions helps appreciate the significance of the ruling.

Article 13(4) of the India–Mauritius DTAA provides that capital gains from the sale of shares of an Indian company by a Mauritius resident are taxable only in Mauritius — and since Mauritius does not tax such gains domestically, this effectively results in zero tax. This provision was the foundation of the “Mauritius Route” and was the treaty benefit Tiger Global sought to claim.

Section 90(4) of the Income Tax Act requires a non-resident claiming treaty benefits to furnish a Tax Residency Certificate from the competent authority of their country of residence. However, as clarified by the Supreme Court in this judgment, Section 90(4) only prescribes a minimum condition — it does not make the TRC conclusive or unanswerable proof of residence.

Section 90(2A) of the Income Tax Act is the provision that gives GAAR its overriding power over tax treaties. It states that treaty benefits shall be available only if the provisions of Chapter X-A (GAAR) do not apply. This means that even where a DTAA grants an exemption, GAAR can step in and deny it if the arrangement is found to be an impermissible tax avoidance arrangement.

Chapter X-A of the Income Tax Act (Sections 95–102), which contains India’s General Anti-Avoidance Rules, defines an “impermissible avoidance arrangement” as one whose main purpose is to obtain a tax benefit and which is entered into through means not ordinarily employed for bona fide commercial purposes, or lacks commercial substance, or misuses the provisions of tax law. An arrangement lacks commercial substance if it does not have a significant effect on the business risks, cash flows, or economic rights of the parties involved — other than the tax benefit itself.

Rule 10U(2) of the Income Tax Rules, 1962 clarifies that GAAR applies to any arrangement that results in a tax benefit on or after 1 April 2017, regardless of when the arrangement was entered into. This was the critical provision that disentitled Tiger Global from claiming grandfathering protection.

The Court also discussed two landmark earlier Supreme Court decisions: Union of India v. Azadi Bachao Andolan (2003) and Vodafone International Holdings BV v. Union of India (2012), both of which had previously upheld the use of the Mauritius Route and treaty shopping. However, the Court distinguished these cases by noting that both were decided before GAAR was introduced and before Section 90(2A) was enacted — meaning the statutory landscape has fundamentally changed since those decisions.

Conclusion by the Court

The Supreme Court allowed the Revenue’s appeal and set aside the Delhi High Court’s judgment. It restored the Authority for Advance Rulings’ original decision rejecting Tiger Global’s application. The Court’s conclusion rested on four clear findings:

• Tiger Global’s Mauritius companies were conduit entities with no real commercial substance in Mauritius. Their control, management, and decision-making authority effectively resided in the USA with the fund’s principal.
• A Tax Residency Certificate from Mauritius, while necessary, is not a conclusive or unassailable shield against scrutiny. Post the introduction of GAAR and Section 90(2A), the tax authorities are entitled to examine the true nature and purpose of the arrangement.
• GAAR applies to Tiger Global’s exit transaction because the tax benefit (capital gains) arose in 2018, which is after 1 April 2017. The grandfathering protection under GAAR does not apply based on the date of exit, not the date of investment.
• Since the arrangement is prima facie an impermissible tax avoidance arrangement, Tiger Global is not entitled to the capital gains exemption under Article 13(4) of the India–Mauritius DTAA. The capital gains from the Flipkart exit are taxable in India.

The total tax demand against Tiger Global, inclusive of tax, interest, and penalties, is estimated at approximately INR 14,500 crore (approximately USD 1.59 billion). The final amount payable will be determined through subsequent assessment proceedings.

It is important to note what this judgment does not say. The Court did not hold that all Mauritius investment structures are automatically abusive. It did not declare treaty shopping to be illegal per se. It did not formally apply GAAR or determine the final tax payable by Tiger Global — those questions remain open at the assessment and appellate stage. The ratio of the judgment is jurisdictional in nature: it affirms the AAR’s right to refuse an advance ruling where the transaction is prima facie designed to avoid tax. The ultimate tax dispute will be settled in assessment proceedings.

For foreign investors, tax advisors, and businesses with offshore holding structures, the Tiger Global judgment delivers a clear and urgent message: the era of relying on TRCs and formal treaty documentation as an automatic or conclusive shield from Indian taxation is over. Investors must ensure that their offshore entities have genuine commercial substance — real decision-making, local management, independent governance, and actual economic activity — in the country through which they claim treaty benefits. Where substance is absent, GAAR can and will apply, even to pre-2017 investments. The Supreme Court has made it unambiguously clear that Indian tax law will look beyond the legal form of a transaction and assess its true economic and commercial character.

This ruling is expected to have far-reaching consequences for private equity funds, venture capital investors, and multinational companies that have historically used the Mauritius or Singapore routes to invest in and exit from Indian businesses. Existing structures must be urgently reviewed and, where necessary, strengthened to ensure compliance with India’s evolving substance-based tax enforcement framework.
