How is salary tax calculated in Mauritania?

Mauritania taxes employment income (ITS) on a progressive scale. On an annual basis the first MRU 72,000 is tax-free, then 15% to MRU 108,000, 25% to MRU 252,000 and 40% above that. Gross salary is taxed without professional-expense deductions.

Is there a tax-free threshold in Mauritania?

Yes. Income up to MRU 6,000 a month (MRU 72,000 a year) is taxed at 0%, built into the scale. The brackets apply to the rest of the salary.

Can I compare different tax years?

Yes. Use the year selector for 2023, 2024, 2025 and 2026, or turn on the year-comparison view to see two years side by side. The 0/15/25/40 scale has been stable, so results are consistent across these years.

Does this include social security?

No. Employees also pay about 1% to the social-security fund (CNSS), which is documented but not deducted here, so the calculator shows income tax on gross and take-home after income tax only.

Are the brackets monthly or annual?

Mauritania’s official scale is monthly (MRU 6,000 / 9,000 / 21,000 thresholds). This calculator uses the annual equivalent (each threshold multiplied by twelve), so enter your annual gross salary.

Is this calculator accurate for my situation?

It gives a reliable estimate for a standard resident employee on the progressive ITS scale. It does not model business income or the social-security contribution. Check with the Direction Generale des Impots or a tax adviser for your exact figures.

How Mauritania salary tax works

Mauritania taxes employment income (ITS) on a progressive scale. The official scale is monthly — 0% up to MRU 6,000, 15% up to MRU 9,000, 25% up to MRU 21,000 and 40% above that. This calculator uses the annual equivalent: 0% up to MRU 72,000, 15% up to MRU 108,000, 25% up to MRU 252,000 and 40% above that. Only the part of your salary inside each band is taxed at that rate. Gross salary is taxed directly, because the tax code does not provide professional-expense deductions for employees. The scale has been stable across 2023–2026.

Social security and what is not modelled

On top of ITS, employees contribute about 1% of salary to the social-security fund (CNSS); this is documented but not deducted here, so take-home is shown after income tax only. The calculator models standard resident employment income and does not cover business or professional income, which is taxed under separate rules. For exact figures, including any employer-specific deductions, consult the Direction Generale des Impots.
