Australian Tax for Australians and Founders Living or Operating in Mauritius

Direct answer: Mauritius may provide a practical personal or regional-business base, but Mauritius residence or a Mauritian company does not automatically remove Australian tax exposure. Mauritius uses domicile, permanent-place-of-abode and 183/270-day residence tests. Australia and Mauritius have information-exchange and limited additional-benefits arrangements rather than a comprehensive income-tax treaty, making the domestic-law and evidence analysis particularly important.
What changes for an Australian already living or operating in Mauritius
Mauritius individual residence can arise through domicile unless the permanent place of abode is outside Mauritius, 183 days in an income year, or 270 days over the relevant multi-year period.
The Mauritius treatment of foreign income can depend on residence, source, character and remittance; bank and transaction records are therefore important.
Australian residence and CGT event I1 must be tested separately. A Mauritius residence result does not establish the Australian departure date.
A Mauritian company or regional structure needs genuine governance, functions, staff, banking and commercial purpose.
An Australian company can create Mauritius taxable presence through management, a fixed place, employees, services or agents.
Ordinary assumptions based on a comprehensive double-tax treaty should not be imported into the Australia–Mauritius corridor.
Founder and company decision matrix
1. When did Australian residence cease, if at all?
The review compares the Mauritius home, family and expected duration with Australian housing, family, assets, business authority and return pattern. Without a comprehensive DTA, the domestic-law evidence and date reconstruction are especially significant.
2. Which Mauritius residence and foreign-income rules apply?
Domicile, permanent place of abode and day-count tests should be reviewed across the relevant years. Foreign salary, directors’ fees, business income, investments, pensions, dividends, loans and capital receipts should be classified and traced through accounts before local treatment is assumed.
3. Where is the business managed and operated?
If a founder directs an Australian company from Mauritius, company-residence and permanent-establishment issues can arise even where a valid Mauritian company exists. Governance, customer contracting, staff, IP, services and transfer pricing should match the actual regional role.
4. Does earlier advice need review?
A client already in Mauritius may have been advised on Mauritius compliance or Australian returns without a complete departure, CGT, remittance, company-control or treaty-instrument analysis. Extax can reconstruct the position and identify corrections or documentation required.
Worked scenario: the founder is already in Mauritius
An Australian founder lives in Mauritius and operates a Mauritian regional advisory company. The Australian company retains established clients, IP and staff, while the founder negotiates African and Indian Ocean work from Mauritius and receives dividends and management fees. Returns have been filed locally and in Australia, but the departure date, remittance treatment and company operating model have not been reviewed together.
The review must determine Australian departure, Mauritius residence and the treatment of foreign receipts. CGT event I1 may affect founder equity. The Australian company’s management and Mauritius presence must be tested, while the Mauritian company’s service role, staffing, pricing, banking and substance should be documented without assuming comprehensive treaty protection.

Frequently asked questions
Can Extax review my position after I have already moved to Mauritius?
Yes. The work can reconstruct the Australian departure and Mauritius residence timelines, review prior returns and remittances, and test the existing business structure.
Does 183 days in Mauritius make me non-resident of Australia?
No. It may satisfy a Mauritius residence test, but Australian residence is determined separately. There is no comprehensive Australia–Mauritius DTA that substitutes for the domestic-law analysis.
Can a Mauritius company receive all international revenue?
Only where that result reflects the real contracts, people, functions, assets, risks and management. Incorporation and banking alone do not establish the correct allocation of profit.
Review an existing or proposed Mauritius position
Extax can review an arrangement already operating from Mauritius or a proposed move, including Australian residence, Mauritius residence and remittances, CGT event I1, company control, operating substance, permanent establishments, transfer pricing and foreign-tax relief.
