If a resident of Mauritius derives income from a foreign country that has not concluded a tax treaty with Mauritius and foreign income tax is paid on the income, that tax may be credited against Mauritian income tax. The credit is limited on a source-by-source basis to the lesser of the foreign tax paid on the income concerned and the Mauritian income tax payable on the same income.

In the case of foreign source dividends, no credit relief is granted for foreign corporate income tax borne on the profits out of which the dividends are paid (underlying tax).
