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).
