Inventories should be valued at the lower of historical cost or net realisable value. The last in first out (LIFO) basis of valuation is not allowed for tax purposes.
Conformity is required between book and tax reporting. Where the MRA is not satisfied that the basis of valuation is acceptable (e.g. where the LIFO basis has been applied), it will make such adjustment as it believes is appropriate to determine the profits arising from the business carried on.
There is no tax on capital gains in Mauritius. However, certain transactions are taxed as ordinary business profit instead of capital gains. Where a transaction is in the nature of trade, the MRA may take the view that it is an ordinary trading transaction and assess the gains derived as income.
Any gains derived from the sale of shares held for less than six months are classified as trading income and are therefore taxed as ordinary income.
Gains realised from the sale of any property or interest in property acquired in the course of a business, as part of a profit-making undertaking or scheme, are taxable as ordinary income.
Companies, whether resident or not, are exempt from tax on dividends received from resident companies.
Dividend income received from abroad by a company resident in Mauritius (non-GBC1 company) is subject to tax at the rate of 15%. Credit for any foreign tax withheld is given, subject to documentary evidence provided to the MRA.
Dividend income received from abroad by a GBC1 company is subject to tax at an effective rate of 3%. As of January 2019, the deemed FTC regime available to GBC1 companies will be abolished and foreign-source dividends not allowed as deduction in source country will qualify for 80% partial exemption on gross amount received.
A resident company can distribute stock dividends (bonus shares) proportionately to all of its shareholders. Stock dividends per se or convertible into cash are not taxable in the hands of the recipient. Dividends in kind (i.e. other than cash or shares) are treated as taxable benefits.
Interest income received by resident companies (non-GBC1 companies) is liable to tax at the rate of 15%. The interest income (excluding bank interest) will qualify for 80% exemption on gross amount received.
A GBC1 company receiving interest income from abroad is liable to tax at the effective rate of 3%. As of January 2019, the deemed FTC regime available to GBC1 companies will be abolished, and interest income will qualify for 80% exemption on gross amount received.

Royalty income received locally is subject to tax at the rate of 15%.
Royalty income received from abroad is subject to tax at the rate of 15%. Any tax withheld from abroad will be allowed as a foreign tax credit. However, a company holding a GBC1 Licence receiving royalty income from abroad on which no foreign tax is suffered will be entitled to a deemed foreign tax credit of 80% of the Mauritian tax payable.
As of January 2019, royalty income received by a GBL will be taxed at the rate of 15%.
Resident corporations are taxed on their worldwide income, but tax credit and treaty relief is generally available in order to avoid double taxation (see Foreign tax credits in the Tax credits and incentives section for more information).
Undistributed income of foreign subsidiaries is not subject to any special taxation as long as the income of the foreign subsidiary before distribution is not included in the accounts of the local parent company. Dividends paid by the foreign subsidiary to the local parent company will, however, be taxable to the latter, whether or not such dividends are actually received in Mauritius.
