Mauritius faces a crucial test of its long-standing status as a low-tax gateway for cross-border capital as a raft of new corporate taxes threatens to erode bank profitability, according to Moody’s Ratings.
Banking Sector Profitability Under Pressure in Mauritius
Lenders across the Indian Ocean financial hub are grappling with a tightening fiscal regime designed to plug domestic budget pressures. According to industry estimates cited by Moody’s, the changes have lifted the effective tax rate for foreign-owned banks to as much as 22% from 4.7% previously. For key domestic banks, the rate climbed to 32% from 18%.
Firms navigating these shifts include institutions such as Mauritius Commercial Bank and SBM Bank (Mauritius), alongside local units of Standard Chartered, Standard Bank, and Absa. Persistent budget deficits—worsened by external pressures, weak growth, and delayed foreign funding—have inflated the country’s debt to an estimated 88% of gross domestic product, up from 64% five years ago.
Did you know? Financial services represent a central pillar of the Mauritian economy, contributing as much as 14% of overall output as the nation positions itself as a leading international financial center for Africa, the Middle East, and Asia.
New Fiscal Charges and Minimum Tax Rules
The government rolled out several new fiscal charges to capture additional revenue. Christos Theofilou, vice president at Moody’s Ratings, noted in an interview that higher taxes and lower distributions to the population have impacted both the corporate sector and households.
The new measures include a 2% corporate climate responsibility levy and a 2.5% tax on chargeable income from domestic operations. Additionally, authorities introduced a fair-share contribution on profits and a 15% minimum tax for multinational groups to retain revenues within the island economy.
Premier and Finance Minister Navinchandra Ramgoolam stated in his budget speech that the fair-share contribution will help prevent a downgrade for the country’s investment-grade sovereign rating.
Bank Adaptations and Robust Capital Buffers
To protect profit margins, lenders are actively adapting their business models. Institutions are ramping up lending and scaling digitalization efforts to boost efficiency.
Robust capital reserves offer a vital cushion against the new fiscal burdens. Core capital stood at 18.4% by June 2025, nearly triple the 6.5% minimum regulatory requirement, according to Moody’s data.
“We expect profitability to remain solid, but to be lower because of the higher taxes,” Theofilou said. While concerns persist regarding international competitiveness, authorities are attempting to make the jurisdiction more attractive through non-tax incentives and measures.
