India-Mauritius tax treaty scrutiny tightens for investment structures

2026-10-15 · 1 source · Economic Times CFO

In short

India’s tax treaty rules with Mauritius are getting tougher, according to a publisher summary. The new Principal Purpose Test puts more focus on whether Mauritius-based investment structures have a real business reason and substance.

This matters for investors using those structures to claim treaty benefits. The reporting does not say which deals are affected or how many may be reviewed.

What the reporting says

India's Mauritius tax treaty scrutiny tightened as the new Principal Purpose Test puts commercial rationale, substance and purpose of Mauritius-based investment structures under greater focus, according to tax experts cited in publisher summaries. The reporting does not name a specific filing, date, or affected deal, and it does not say how many structures may be reviewed. The immediate effect is greater uncertainty for treaty benefit claims.

Why it matters

India's Mauritius DTAA rules are being viewed as tighter because the new Principal Purpose Test puts commercial rationale and substance under closer scrutiny, according to the available summary. That could affect investors and funds that rely on Mauritius-based structures for treaty benefits. The reporting does not identify any specific case, transaction, or date, so the scale of the impact is unclear.
