7.5% on interest. The lowest rate India offers any country.
The 1982 India-Mauritius DTAA, even after the 2016 protocol that closed the capital-gains exemption for post-2017 acquisitions, still gives Mauritius the LOWEST interest rate (7.5%) and one of the lowest dividend rates (5%/15%) of any Indian DTAA. For a Port Louis fund administrator with ₹35L in Indian MFs and a Bandra rental, that's about MUR 67,800 a year. Plus six past years of NRO FD interest still reachable via Section 119(2)(b) for anyone who's been at default 30% since the protocol date.

Where Mauritius NRIssave, and where they don't
Green bars = your treaty rate. Red bars = what your bank actually deducts. The gap is your money.
3 income types(capital gains, rental, etc.) where the treaty rate matches the default are not shown above. Some treaties include Article 22 provisions for “other income” — eligibility depends on your specific income structure. A CA will confirm which rates apply to you.
What is TDS?
Tax Deducted at Source. Whenever you earn income from investments in India — FD interest, mutual fund returns, dividends — the payer (bank, AMC, or company) deducts tax before crediting your account. For NRIs, this is usually 30% under Section 195, regardless of what you actually owe.
What is DTAA?
Double Tax Avoidance Agreement. A treaty between India and Mauritius that caps the tax rate on your Indian income. For example, interest is capped at 7.5% instead of 30%. The difference is legally yours to claim back.

A typical Mauritius NRI's story
Based on Two distinct populations. (1) ~12,000 NRIs on Indian passports — concentrated in Port Louis CBD (financial services at MCB, SBM, IPRO/Imara), Ebene CyberCity (IT/BPO/back-office for Indian outsourcing), and Grand Baie (consultancy, hospitality, retirees). Most are senior bankers, fund administrators, IT consultants, or Mauritius-based directors of Indian fund management entities. (2) ~770,000 PIOs/OCIs — Mauritian citizens of Indian origin (Indo-Mauritian, Bihari/UP-heritage majority, Tamil/Telugu/Marathi minority), multi-generation, do not file Indian ITR unless they hold direct Indian-source income., the kind of people in the Indian community in Mauritius.

Step-by-step for Indians in Port Louis
Apply to the Mauritius Revenue Authority (MRA) via the e-Filing portal (eservices.mra.mu) for a Tax Residence Certificate. Need Mauritius National Identity Card or residence permit, latest income tax return acknowledgement, and a written request specifying India and the relevant Indian financial year. The MRA issues the TRC under Section 73A of the Income Tax Act 1995 (Mauritius). Free, typically 5-15 working days. The MRA will not issue a TRC unless you've filed a Mauritius return for the relevant year.

Things Mauritius NRIs should know
Pitfalls we've seen Indians in Port Louis face
We work with the Indian community in Mauritius every day. These are the traps that cost real money.
Post-2017 protocol grandfathering: shares acquired in Indian companies BEFORE 1 April 2017 are exempt in India under the old treaty (subject to the LOB / Mauritius expenditure test of MUR 1.5M+ in prior 12 months). Acquired ON or AFTER 1 April 2017: India taxes the gain at source. Most pre-2017 holdings have already been monetised; for those still holding, lot-by-lot tracking is mandatory.
Mauritius income year is 1 July - 30 June, not the Indian April-March or the calendar year. Your TRC will state a Mauritius income year that doesn't align cleanly with the Indian FY. Bank submissions need to map the TRC validity period across two Indian FYs.
Solidarity Levy on individuals was abolished from Y/A 2023-24. Replaced by the progressive 11-band PIT structure (0% to 20%). Indian-source dividend/interest received in Mauritius now lands inside these graduated bands rather than the old 25% surcharge layer; FTC for Indian tax via Article 23 reduces double-tax.
PIO/OCI vs NRI distinction matters more here than anywhere. The Indo-Mauritian community is large and multi-generation, mostly Mauritian citizens, not NRIs. Indian-passport-holders on assignment / business setup are the actual NRI population (~12,000). Form 10F and TRC apply only to those holding NRI status.
Mauritius personal income tax slabs (post-2023 reform, Y/A 2023-24 onwards): 11 graduated bands — 0% up to MUR 390K, then 2%, 4%, 6%, 8%, 10%, 12%, 14%, 16%, 18%, and 20% on income above MUR 2.39M. Indian-source income remitted to Mauritius lands inside these slabs after the FTC offset under Article 23.
The 2016 protocol's LOB clause (Article 27A) is a real test: a Mauritius shell with no employees, no presence, no substantive business CANNOT claim treaty benefits. The MRA's substance criteria (employees, expenditure, decision-making) are routinely audited. For genuine NRIs working in Mauritius this is automatic; for treaty-shopping structures, it's a deal-breaker.
