In a recent judgement, the Supreme Court in the case of Authority for Advance Rulings (Income-tax) vs Tiger Global International II Holdings [2026] 182 taxmann.com 375 (SC)[1] has revisited the scope of treaty protection in cross-border investment structures, particularly in the context of the sufficiency of Tax Residency Certificates (TRCs), the interpretation of grandfathering provisions under tax treaties, and the application of domestic anti-avoidance rules such as GAAR. The decision is significant as it has the potential to alter long-standing assumptions regarding treaty entitlement and has wide-ranging implications for investments structured through intermediary jurisdictions.
I. Background
The matter involving the taxation of the sale of shares of Indian companies, or the sale of shares of overseas companies deriving value substantially from Indian companies, has been litigated for many years. In this context, two judgements of the Indian Supreme Court, UOI vs Azadi Bachao Andolan [2003] 263 ITR 706 (SC) and Vodafone International Holdings B.V vs UOI [2012] 341 ITR 1 (SC), have a significant place in shaping the jurisprudence on this subject. The fact patterns in both judgements involved investments originating from or routed through a Mauritius-registered entity or fund, which claimed tax exemptions under the applicable tax treaties as they stood prior to 1 April 2017. They further raised the issue of whether a Tax Residency Certificate (TRC) issued by the Mauritian tax authorities should be considered sacrosanct or whether Indian authorities can challenge the same.
The issues arising in the present Tiger Global case emerge against this jurisprudential backdrop and involve a broadly similar investment structure and treaty-related controversy.
