Experts Downplay Investor Fears Over Mauritius Tax Protocol
Mauritius and India have updated their tax agreement.
The update adds a rule called the Principal Purpose Test.
This rule can deny a tax benefit if getting that benefit was one of the main reasons for a transaction.
Some investors worry that Indian tax officials will gain very broad powers.
Tax experts say the rule does not create completely new powers because similar challenges were already possible under GAAR.
They say the main change is that challenges can now be made directly under the tax treaty.
Investors can still appeal decisions and may use a process involving both countries’ tax authorities.
The rule applies going forward, while certain older investments remain protected.
Mauritius’s Cabinet ratified a 2024 protocol amending its tax treaty with India.
The protocol introduces a Principal Purpose Test to counter treaty shopping and other treaty-abuse practices.
Experts say the measure provides a treaty-based scrutiny route rather than new or blanket anti-abuse powers.
Investors may still face uncertainty because the test examines the purposes and facts behind each transaction.
The Central Board of Direct Taxes said the measure is prospective and preserves grandfathering for investments made before April 1, 2017.

Expert Reassurance
Investor Concerns
Extent of tax authority powers
Expert Reassurance
Experts say the Principal Purpose Test is an internationally accepted anti-abuse standard aimed mainly at treaty shopping, not a blanket power to deny benefits.
Investor Concerns
Investors are concerned that the test could allow Indian tax authorities to apply broader scrutiny to Mauritius-based investments.
Change in enforcement
Expert Reassurance
Experts say the main change is the route: treaty challenges can be raised directly under the protocol rather than only through the existing General Anti-Avoidance Rule process.
Investor Concerns
Investors may see the treaty-based route as an additional source of challenge and uncertainty, even if scrutiny was already possible under existing rules.
Impact on genuine investors
Expert Reassurance
Experts say genuine investors should not lose treaty benefits merely because they invested through Mauritius, and they retain appeal and mutual-agreement remedies.
Investor Concerns
The purpose-based and fact-intensive nature of the test could create uncertainty where tax considerations were part of the reason for choosing Mauritius.
