Tiger Global Ruling: Implications for Capital Gains, Treaty Use and Tax Certainty
The recent Supreme Court decision involving Tiger Global and the capital gains arising from the transfer of shares of Walmart India through the Mauritius route has reaffirmed India’s right to tax such gains. Even though the full text of the decision is awaited, the outcome has reignited debate around tax certainty, treaty protection, and fairness in cross-border taxation, particularly in fast-growing markets like India that depend heavily on foreign capital.
This development sits at the intersection of domestic law, international tax treaties and evolving global norms on base erosion and profit shifting. It also underlines that while tax treaties promote investment and prevent double taxation, they cannot be treated as a shield for “double non-taxation” or “round-tripping” structures that are aimed at avoiding tax everywhere.
Role and Purpose of Tax Treaties in the Global Tax Framework
Modern tax treaties trace their roots to multilateral efforts that started decades ago. The OECD introduced its first Model Tax Convention in 1963, and the United Nations followed with its own model in 1980. Nearly all bilateral tax treaties draw their basic design from these model conventions.
Core Objectives of Double Taxation Avoidance Agreements
Tax treaties are not mere instruments of relief; they are designed to balance the interests of capital-exporting and capital-importing jurisdictions. Their principal objectives can be regrouped as follows:
Enabling cross-border investments
- Removing or lowering tax barriers between jurisdictions
- Providing mechanisms to allocate taxing rights between source and residence countries
Preventing double taxation
- Ensuring that the same income is not taxed twice in a manner that makes cross-border activity commercially unviable
- Offering relief through methods like tax credits, exemptions or reduced withholding rates
Curbing tax evasion and double non-taxation
- Treaties seek to prevent not only double taxation but also situations where income escapes tax in all jurisdictions due to mismatches or artificial structures
- Anti-abuse provisions, limitation-of-benefits and principal-purpose tests are increasingly used for this purpose
Promoting coherence between tax systems
- Harmonizing key concepts such as “permanent establishment”, “residence”, and “business profits”
- Streamlining procedures for withholding tax, capital gains, salaries, and granting of tax credits and Tax Residency Certificates (TRC)
Facilitating dispute resolution and information exchange
- Offering mechanisms like Mutual Agreement Procedure (MAP) to resolve treaty disputes
- Providing a framework for exchange of information, including on request, spontaneous and automatic exchange
Providing tax certainty for long-term investment
- Predictability of tax outcomes is critical for investors committing large, long-horizon capital
- Stable and reasonably foreseeable tax rules are essential for resource mobilization in developing economies
In practice, these aims must be reconciled with domestic tax sovereignty and the imperative to protect tax bases from erosion.
Treaty Interpretation and the Primacy of Domestic Law
Vienna Convention and Interpretation Standards
Interpretation of treaty provisions across jurisdictions is generally guided by the Vienna Convention on the Law of Treaties, May 1969, which lays down principles such as:
- Treaties must be interpreted in good faith
- Words are to be understood in their ordinary meaning in context
- Object and purpose of the treaty are central to interpretation
However, the practical impact on any given assessee depends on how local courts and tax authorities apply these principles in the context of domestic law. Where there is a gap or silence in the treaty, domestic law often steps in to fill that vacuum.
