India Supreme Court Ruling on Tiger Global–Flipkart Deal Spurs Investor Jitters Over Mauritius Tax Route

A landmark ruling by India’s Supreme Court against Tiger Global has triggered fresh anxiety among foreign investors who have long channelled funds into India through Mauritius to benefit from favourable tax treaty provisions. The court held that Tiger Global’s 2018 sale of a $1.6 billion stake in Flipkart to Walmart should be taxed in India, concluding that the firm used Mauritius-based entities as “conduit” companies in an “impermissible tax-avoidance arrangement.” The decision is being seen as a major shift that could strengthen New Delhi’s authority to challenge treaty-based tax benefits claimed through offshore structures.

Legal experts say the judgment has wide implications because it confirms that India’s anti-tax evasion framework, including GAAR (General Anti-Avoidance Rules), can override treaty protections when deals lack genuine commercial substance. The Supreme Court noted that merely holding Mauritius Tax Residency Certificates is not sufficient proof of legitimate business operations, and authorities can deny treaty benefits if they establish that funds were routed through Mauritius primarily to avoid Indian taxation. Although the India–Mauritius treaty was revised in 2017 to end the tax-free regime for new investments while protecting earlier transactions through a grandfathering clause, the ruling has raised concerns that older structures may now face renewed scrutiny.

The judgment comes at a time when investors remain sensitive to India’s tax environment, which has often been criticised for prolonged litigation and interpretational uncertainty. Lawyers report receiving calls from nervous clients in the U.S. and Europe as they review the extensive ruling and assess its impact on past and future exits. While the Indian government has defended the ruling as an effort to curb tax abuse rather than discourage investment, experts warn that heightened scrutiny of legacy structures could reshape the M&A and investment landscape, potentially affecting confidence in treaty-based investment routes.
