Tiger Global vs India: The ₹14,500 Crore Tax Showdown

In 2018, one of the biggest deals in Indian business history closed. Walmart bought control of Flipkart for roughly $16 billion, and early investors celebrated some of the largest exits the startup world had ever seen. Tiger Global, the US investment firm, sold its stake for about $1.6 billion.

Then came a question that took years, three forums and a Supreme Court bench to answer: who gets to tax that profit?

Tiger Global had backed Flipkart since its early days. It did not hold the shares directly, though. The investment sat inside a chain of companies: Mauritius entities on top, and a Singapore holding company for Flipkart beneath them.

That structure was not unusual. For two decades, Mauritius was the favourite route for money entering India, largely because of the India–Mauritius tax treaty. Under the old terms, profits from selling shares were taxed in Mauritius, and Mauritius charged no capital gains tax. The result: zero tax on the gain in both countries.

India had amended the treaty from 1 April 2017, but it protected investments made before that date. Tiger Global’s lawyers pointed to exactly that protection.

So the sellers asked the tax department for a “nil” withholding certificate. Their case was simple: our shares are old, our entities hold valid Mauritian tax residency certificates, and the treaty says India cannot tax us.

The tax authorities saw a different picture. In their view, the Mauritius companies were conduits: shells placed between the real investor and the investment, mainly so the profit could slide through a treaty without being taxed.

The Authority for Advance Rulings sided with the tax department and refused treaty benefits.

Tiger Global challenged that in the Delhi High Court. In August 2024, the High Court ruled in its favour and quashed the ruling. For a moment, the treaty-based structure looked safe.

The tax department appealed to the Supreme Court.

January 2026: The Supreme Court Decides

In January 2026, India’s Supreme Court reversed the High Court. It held that the arrangement was an impermissible tax-avoidance structure, one that could not enjoy treaty protection.

Three ideas sit at the heart of the judgment:

• Holding a tax residency certificate (TRC) from Mauritius was not enough on its own. Authorities can look beneath it and ask who really controls the money and why the structure exists.
• The court enforced the General Anti-Avoidance Rule (GAAR), which allows authorities to deny treaty benefits, disregard intermediary entities and tax the income in India.
• Protection for pre-2017 investments was never meant to cover arrangements built mainly to avoid tax.

The result: a tax demand of about ₹14,500 crore was restored. The exact liability and any penalties will be worked out in later assessment proceedings, so the story is not fully over.

This was not just a fight between one fund and the tax department. It changed the ground rules for cross-border investing in India.

For foreign investors and private equity funds: a clean treaty paper trail is no longer enough. Substance matters: real decision-making, real commercial reasons and real presence in the treaty country.

For past deals: experts say completed exits may now face fresh scrutiny, especially where intermediary entities look like conduits.

For traders: advisers have flagged that foreign traders operating in India’s derivatives markets through Mauritius and Singapore entities could also come under closer examination if key decisions are made elsewhere.

For startups raising money: if your cap table includes funds that invested through offshore structures, your investors’ tax position may become part of the conversation at the time of exit.

The judgment reflects a global shift. Countries are less willing than ever to let treaties be used in ways their drafters never intended. The Supreme Court’s message was clear: India keeps the right to tax income that arises within its borders, and paperwork alone cannot override that.
