Why the Supreme Court’s Tiger Global verdict matters: It may make foreign investors reprice their risks

Subscribe to enjoy similar stories. The Supreme Court’s ruling in the Tiger Global-Flipkart stake-sale case has been framed as a blow against tax-treaty abuse. In reality, it does something far more consequential: it rewrites the operating assumptions under which foreign capital has been invested in India for decades.

While the judgement is fact-specific, its reasoning dismantles the comfort investors drew from treaty residency, grandfathering assurances and carefully structured exits. It resets India’s investment jurisprudence, with ramifications for private equity (PE), venture capital (VC), foreign portfolio investors (FPIs) and long-term strategic capital. The most immediate consequence of the ruling is for pre-2017-18 PE, VC and foreign direct investments, particularly those routed through Mauritius.

For years, such structures relied on tax residency certificates, board resolutions and governance frameworks to demonstrate control outside India. The Supreme Court has made it clear that paper compliance is no longer enough. Most Mauritius special purpose vehicles (SPVs) were post-box entities by design, with structures ‘expert-engineered’ to satisfy India’s tax treaty with Mauritius in form—periodic board meetings, internal approvals and decision-making records—without much real operational or commercial substance.

This model may now fail, unless investors can demonstrate genuine economic substance and decision-making at the treaty jurisdiction level. It would be incorrect to claim that all pre-2017-18 exits are automatically taxable. But it is undeniable that tax certainty, the very promise on which those investments were made, has been severely weakened.
