Global Business Company (GBC) Tax in Mauritius
How GBCs are taxed in Mauritius, the 80% partial exemption, enhanced substance rules and Financial Services Commission requirements.
The Global Business Company (GBC) remains Mauritius’ flagship vehicle for cross-border investment, particularly into Africa and Asia. Post-2019 reforms replaced the deemed foreign tax credit with the 80% partial exemption and introduced sharper substance tests policed by the Financial Services Commission (FSC).
Tax treatment
GBCs are taxed at the standard 15% rate. Qualifying foreign-source income streams benefit from the 80% partial exemption, resulting in an effective 3% rate — but only if the company meets substance requirements.
Substance requirements
The GBC must carry out core income-generating activities in Mauritius, employ an adequate number of suitably qualified persons, and incur adequate operating expenditure — proportionate to the level of activity.
FSC and MRA reporting
Beyond corporate tax filings, GBCs report annually to the FSC and must maintain audited financial statements regardless of size.
