Corporate Tax in Mauritius: The 15% Rate, Explained
Why Mauritius still has one of the most attractive corporate tax regimes in Africa, and how the partial exemption regime works in 2026.
The headline rate
Mauritius levies a flat 15% corporate income tax on resident companies. Combined with a wide treaty network and no capital gains tax, it remains one of the most competitive regimes on the continent.
Partial Exemption Regime (PER)
Certain streams of income — foreign-source dividends, interest, ship/aircraft leasing — qualify for an 80% partial exemption, bringing the effective rate down to 3% if substance requirements are met.
Substance requirements
To claim PER, a company must employ a minimum number of suitably qualified persons and incur a minimum operating expenditure in Mauritius, proportional to its activities. The MRA scrutinises this closely.
Corporate Social Responsibility (CSR)
Profitable companies must set aside 2% of chargeable income for CSR — either through approved NGOs, ministry-approved programmes, or by paying it to the MRA.
Filing and instalments
Companies file the annual return within 6 months of year-end. Advance Payment System (APS) instalments are due quarterly for companies with turnover above Rs 10 million.
Getting this wrong is expensive
Misapplying PER without substance triggers back-tax at 15% plus penalties. Have your PER position reviewed annually.
