India Shields Pre-2017 Mauritius Investments from Anti-Abuse Tax Rules

The Indian government has moved to provide definitive tax certainty to international markets by confirming that General Anti-Avoidance Rules (GAAR) will not be applied retrospectively to investments made prior to 1 April 2017.

The clarification, which specifically safeguards legacy investments routed through Mauritius, was formally noted by the Cabinet during its meeting on Friday, 3 April.

The decision follows the publication of the Income Tax (Amendment) Rules 2026 by India’s Central Board of Direct Taxes (CBDT) on 31 March 2026.

Safeguarding Historical Arrangements

Under the new provisions, GAAR will strictly apply only to tax arrangements entered into on or after the April 2017 cutoff.

This effectively creates a “grandfathering” clause for all prior holdings, alleviating fears that older structures could be penalised under modern anti-abuse frameworks.

The move comes as a response to heightened anxiety within the investment community following a landmark Indian Supreme Court ruling in the Tiger Global case.

That judgement had sparked significant debate over whether the tax authorities might seek to apply anti-avoidance measures to historical transactions.

Diplomatic Assurances

The resolution of this fiscal ambiguity follows high-level bilateral discussions. During a recent visit to India, the Mauritian Prime Minister raised the matter directly with his counterpart, Narendra Modi.

Prime Minister Modi reportedly assured the Mauritian leadership that India would honour the existing benefits provided under the Double Taxation Avoidance Agreement (DTAA) between the two nations.

Boosting Investor Confidence

Authorities believe the amendment will provide a vital boost to foreign direct investment and private equity funds. By establishing clear “rules of the road” for taxation—particularly regarding exit strategies—the Indian government aims to:

• Strengthen market confidence in the regulatory environment.
• Ensure fiscal certainty for long-term institutional investors.
• Protect the integrity of the Indo-Mauritius financial corridor.

Official figures and market analysts expect this clarification to stabilize the investment climate for funds managed through the Mauritian financial hub, which remains a primary source of capital for the Indian economy.
