Built for Mauritius NRIsSave 22.5% on interest

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 lower dividend rates (15% for individuals; 5% only for corporate beneficial owners holding ≥10% capital) of any Indian DTAA. For a Port Louis fund administrator with ₹1.05Cr in Indian MFs and a Bandra rental, that's about MUR 203,400 a year. Plus five past Assessment Years of NRO FD interest still reachable via Section 119(2)(b) for anyone who's been at default 30% since the protocol date.

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.

Real numbers

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. Note the limit: in Tiger Global (Supreme Court, January 2026) the court held GAAR can override treaty relief even for shares bought before that date, and that a TRC does not stop the enquiry. That ruling targeted a conduit structure. A genuine direct holding by a real treaty resident is not what it was aimed at. 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. Income now sits inside the progressive PIT bands. Three bands at 0% / 10% / 20% from 1 July 2025 (Finance Act 2025), 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 Finance Act 2025, effective 1 July 2025): 3 bands, 0% up to MUR 500,000, 10% on next MUR 500,000, 20% on the remainder. The earlier 11-band structure was repealed by the Mauritius Budget 2025-26. A Fair-Share Contribution of a flat 15% applies to individual income above MUR 12M (the MUR 24M / 20% threshold is the company figure, not individual). 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.

CA help for Mauritius NRIs

When Indians in Port Louis need a Chartered Accountant

Mauritius taxes residents on income derived from or remitted to Mauritius, and it has a long-standing tax treaty with India. The treaty's capital-gains position changed under the 2016 protocol: gains on Indian shares acquired before 1 April 2017 remain grandfathered, while shares bought afterwards are taxable in India, so the date you bought matters. These are the situations that come up most often for NRIs in Mauritius.

Mauritius NRIs who recovered

Real people. Real money back.

“My Indian CA had been filing at default rates for 20 years. No treaty claim, no Form 10F. The Kenya DTAA caps interest at 10%, and with five years of condonation plus Section 244A interest, TrustNRI recovered more than I'd expected. The property sale Form 13 the next year was the real cherry.”

Questions from Mauritius NRIs

Everything Indians in Port Louis ask us

50+ answers. Hover on for plain-English explanations.

Short version: India treats you as an and deducts 30% on your interest by default. That's the rate for “foreigner, no treaty claimed.” But India and Mauritius have a tax treaty (called ) that caps this at 7.5%. The difference, 22.5%, is money you're entitled to but aren't getting back. Most Indians in Port Louis don't know this exists.

The exceptions that change the answer

Where the general rule stops applying to you

Every rule below has a carve-out, a cut-off date or a condition that flips the answer. These are the ones that decide real cases.

Surcharge bands for individuals

Right now: 10% above Rs 50 lakh, 15% above Rs 1 crore, 25% above Rs 2 crore, 37% above Rs 5 crore (old regime)

Where it works differently

The income is capital gains under s.111A, 112 or 112A
Surcharge on that component is capped at 15%, whatever the total income.
Proviso inserted by Finance Act 2022, which caps surcharge on capital gains at 15%.
Income crosses a band by a small amount
Marginal relief caps the extra tax at the extra income.
Standard marginal-relief computation, routinely omitted from NRI calculators.
The taxpayer is a non-resident
The same bands apply. There is no separate NRI surcharge schedule.
Surcharge is income-level based, not residence based.

Commonly got wrong

  • An NRI with a large property gain pays 37% surcharge. Capital-gains surcharge is capped at 15%, and the 37% band does not exist in the new regime at all.Surcharge on the capital-gains component is capped at 15%. Other income follows the normal bands, which top out at 25% in the new regime.

Primary residence test: days in India

Right now: 182 days

Where it works differently

The person is an Indian citizen leaving India for employment abroad, or as a crew member of an Indian ship
Only the 182-day test applies. The 60-day secondary test is disabled.
Explanation 1(a) to s.6(1)
Counting days
The day of arrival AND the day of departure both count as days in India.
Settled administrative practice; partial days count as whole days.
The financial year straddles a move
Residence is decided for the WHOLE financial year, not from the date of the move. India has no split-year concept, unlike the UK.
s.6 is a full-year test.

Commonly got wrong

  • You become an NRI the day you leave India. True for FEMA, false for income tax. Under FEMA residence changes on departure with intent; under the Income-tax Act it is a full-year day count.Name which law you mean. Say 'non-resident under FEMA from the day you leave' or 'non-resident for income tax if you are in India under 182 days in that financial year'.
  • India has split-year treatment. It does not. Only the treaty tie-breaker resolves a dual-residence year.Point to Article 4 of the relevant DTAA.

Treaty rate on Indian dividends

Right now: Domestic rate 20% plus surcharge and cess; most treaties cap it at 10-15% under Article 10

Where it works differently

A TRC and Form 10F are furnished to the registrar or company
The treaty rate applies at source. Without them the full 20% plus surcharge and cess is deducted and you recover it by filing.
s.90(4) and (5).
The exact rate matters
It is per treaty, not a single number. Check the country entry. Some treaties are 10%, some 15%, and Italy's dividend article can be WORSE than the domestic rate.
Never quote one figure across countries.
Claiming the treaty rate
The s.115A(5) filing exemption is lost, so an Indian return becomes necessary.
That relief needs TDS at not less than the s.115A rate.

Commonly got wrong

  • The DTAA rate on dividends is 10%. It varies by treaty. Quoting one number across countries is wrong, and at least one treaty is worse than domestic law.Check your country's Article 10 rate, commonly 10% or 15%, against 20% plus surcharge and cess under domestic law.

Treaty rate on Indian interest

Right now: Domestic rate 30% plus surcharge and cess on NRO interest; most treaties cap it at 10-15% under Article 11

Where it works differently

The account is NRE or FCNR
Interest is exempt entirely while you are a FEMA non-resident. There is no rate to reduce.
s.10(4)(ii) and s.10(15)(iv)(fa).
The bank refuses the treaty rate without a PAN
Rule 37BC and the Serum Institute / Danisco line say s.206AA cannot override a treaty rate.
See the case register.
The exact rate matters
Per treaty. Do not quote a single figure across countries.

Commonly got wrong

  • All NRO interest is taxed at 30%. That is the domestic default. With a TRC most treaties bring it to 10-15%.30% plus surcharge and cess by default. With a TRC and Form 10F, your treaty's Article 11 rate applies, commonly 10-15%.
