How to become a tax resident
- no explicit statutory definition of individual tax residence in Mauritanian tax law; residents and non‑residents are primarily distinguished by whether they are Mauritanian nationals or foreign/non‑resident individuals for income tax on wages
- Mauritanian nationals are taxed on all personal income including foreign‑sourced income
- non‑resident individuals (generally foreign individuals) are taxed only on income attributable to their employment or activities in Mauritania
Long-stay residence is obtained through standard visas and residence cards tied to work or business activity, with no special investment, nomad, or easy passive-residence route for self-funded individuals.
How to break residency
hard to leaveMauritanian nationals remain taxable on worldwide personal income under domestic law, and there is no clear statutory residence-break test, so ceasing to be taxed like a resident typically requires loss of Mauritanian status or relying on a treaty tie‑breaker rather than simply spending fewer days in the country.
