Corporate - Taxes on corporate income

Last reviewed - 31 March 2026

Mauritanian companies are taxed in accordance with the territoriality principle. Consequently, companies that carry out their activities outside of Mauritania will not be taxed in Mauritania for those profits. However, foreign companies (resident and non-resident) are subject to Mauritanian Corpotate Income Tax (CIT for their Mauritanian source of benefit, and the profit realised from services and goods exportation from Mauritanian companies will be taxed in Mauritania.

Mauritania applies three regimes for taxing corporate profits:

  1. Normal Real Profit Regime 
  2. Intermediate Real Profit Regime
  3. The simplified tax regime for commercial fishing.

The Normal Real Profit Regime applies to companies with annual turnover exceeding 5,000,000 Ouguiya (before tax).If a company’s turnover falls below this threshold, it moves to the Intermediate Real Profit Regime only after two consecutive years below the limit.For businesses starting or ceasing operations during the year, the turnover threshold is adjusted proportionally to the period of activity.

CIT Rate

Normal Real Profit Regime: tax due is the higher of 25% of the net taxable profit or 2.5% of the taxable income. 

Intermediate Real Profit Regime: tax due is the higher of 25% of the net taxable profit or 2.5% of the taxable income. 

A tax rate of  25% of the net taxable profit or 2.5% of the commission or margin received affects activities intermediary business operations, including the resale of telephone cards and audiovisual subscriptions at supplier imposed prices, travel agency services, sales of second hand goods purchased from non taxable persons, and labour contracting.

The incomes from built-up property (e.g. houses, factories, shops, or offices), from non-built property (regardless of their nature), from subletting built and non-built properties, from rents and every service of construction lease not included in the CIT or IBAPP income, and those from property made freely available to a third party without any legally mandate are subject to a property income tax at 10%.
