India’s Supreme Court has clarified that a Tax Residency Certificate alone is no longer sufficient for treaty relief, emphasising the importance of control and economic substance in offshore structures, impacting investors using Mauritius and Singapore routes.
India’s Supreme Court has shifted the ground under one of the country’s most familiar cross-border tax assumptions: a Tax Residency Certificate, or TRC, is no longer enough on its own to secure treaty relief. The ruling matters because it affects how offshore funds, holding companies and private investors structure India-related deals, especially where Mauritius or Singapore vehicles are used to route share sales and claim capital-gains exemptions. According to legal commentary from DLA Piper, the court’s approach turns attention away from paper residency alone and towards where control sits, whether the structure has a real commercial purpose and whether the entity does any meaningful work.
That is a sharp change from the long-standing comfort many investors took from earlier administrative practice. For years, a valid TRC was widely treated as the key document for proving treaty residence, and in effect became a near-automatic pass for treaty benefits. The court has now made clear that it is only the starting point. In the Tiger Global matter decided on 15 January 2026, the bench looked beyond the certificate and asked who actually controlled the investment decisions, whether the Mauritian entities had substance and whether the arrangement had genuine economic logic.
The background explains why the decision lands so heavily. Mauritius became a preferred route for Indian investment after the India-Mauritius tax treaty created a favourable capital-gains position, while Singapore later played a similar role. That set-up helped channel large volumes of foreign money into India, including private equity and portfolio flows. But it also created a long-running tension between treaty planning and anti-avoidance rules. The 2000 CBDT circular and the Supreme Court’s earlier blessing of it had encouraged the view that a TRC could do most of the work. Tiger Global has now narrowed that reading.
For investors, the practical takeaway is that documentation alone will not settle the question. A fund or holding company will need to show that decision-making really happens where it says it does, that local directors are not just rubber-stamping instructions from elsewhere, and that the entity bears genuine economic risk. That matters not only for foreign funds but also for Indian businesses that receive overseas capital through layered structures, because the tax treatment of an exit may now depend on the facts behind the structure rather than the label on the certificate. As the DLA Piper note puts it, the court wants to see substance, not just form.
The wider issue is uncertainty. If the TRC is only prima facie evidence, tax authorities may challenge more structures, and taxpayers may have to prove substance case by case. That may be a cleaner reading of treaty law, but it also creates a more demanding compliance environment. For Indian investors, the message is straightforward: treaty relief is still available, but it is no longer something a certificate can guarantee on its own.
