Let’s face it: navigating corporate tax regimes can feel like a maze designed to trip up even the savviest entrepreneurs. If you’re considering Mauritania (MR) as a base for your company in 2025, you’re likely searching for clarity, efficiency, and—above all—ways to keep more of your hard-earned profits. This guide delivers a data-driven breakdown of Mauritania’s corporate tax system, with actionable strategies to optimize your fiscal footprint and minimize state-imposed costs.
Understanding Mauritania’s Corporate Tax Rate in 2025
Mauritania applies a flat corporate tax rate of 25% on company profits. This means that, regardless of your company’s income level, the same percentage applies—no progressive brackets, no hidden thresholds. The tax is assessed on corporate profits, and the official currency is the Mauritanian ouguiya (MRU). For reference, as of early 2025, 1 MRU ≈ 0.027 USD.
| Tax Type | Rate | Assessment Basis |
|---|---|---|
| Corporate Income Tax | 25% | Corporate profits |
| Special Surtax (see below) | 2% or 25% | Conditional (see details) |
| Branch Withholding Tax | 10% | After-tax profits of foreign branches |
Key Surtaxes and Special Conditions
While the flat 25% rate is straightforward, Mauritania’s regime includes two notable surtaxes that can impact your effective tax rate:
- 2% Surtax: If 2% of the income listed in article 8 (excluding transfers and reversals of charges) exceeds 25% of your net taxable profit, then the 2% rate applies instead of the standard 25%. This is a rare scenario, but it can be a game-changer for companies with high gross income but low net profit.
- 10% Branch Withholding Tax: For foreign companies operating branches in Mauritania, a 10% withholding tax is levied on after-tax profits realized in the country. This is in addition to the regular corporate tax.
Mini Case Study: How the 2% Surtax Works
Suppose your Mauritanian company has MRU 10,000,000 (≈ $270,000) in income (as defined by article 8), but only MRU 700,000 (≈ $18,900) in net taxable profit. 2% of MRU 10,000,000 is MRU 200,000 (≈ $5,400), which is more than 25% of MRU 700,000 (MRU 175,000, ≈ $4,725). In this case, you would pay the 2% surtax (MRU 200,000) instead of the standard 25% corporate tax (MRU 175,000). This mechanism can be advantageous for low-margin businesses.
Pro Tips for Tax Optimization in Mauritania (2025)
- Analyze Your Income Structure
Pro Tip: Review your revenue streams and expense allocations. If your gross income is high but your net profit is slim, you may qualify for the 2% surtax instead of the 25% flat rate. Run the numbers before filing. - Branch vs. Subsidiary: Choose Wisely
Pro Tip: If you’re a foreign entrepreneur, consider whether to operate as a branch or a locally incorporated subsidiary. Branches face a 10% withholding tax on after-tax profits, which can significantly increase your total tax burden. - Stay Currency-Savvy
Pro Tip: Monitor MRU/USD exchange rates when planning profit repatriation or reinvestment. Small fluctuations can impact your effective tax cost in your home currency. - Document Everything
Pro Tip: Mauritanian tax authorities require clear documentation for all income and deductions. Keep meticulous records to avoid disputes and ensure you benefit from the most favorable tax treatment.
