Mauritania’s first cargo of liquefied natural gas left its Atlantic coast in April 2025, the visible result of a decade-long offshore project that finally started paying off. That single fact reframes a lot of what follows in this guide, because a country whose economy has long run on iron ore, fishing and gold is now, for the first time, also an LNG exporter, and the registration, tax and hiring rules covered here sit inside an economy that’s genuinely shifting shape. This guide covers how company formation actually works under Mauritania’s OHADA-based legal system, what a new employer needs to budget for, and where the current gas-driven momentum is real versus still developing.

Why Register a Company in Mauritania?

Mauritania’s Investment Code gives foreign investors the same legal treatment as domestic ones in most sectors, permits full foreign ownership without a mandatory local partner, and guarantees the right to repatriate profits and capital. None of that is unusual among OHADA states, but Mauritania pairs it with a specific and growing set of reasons to actually look at the country rather than treat it as an afterthought next to Senegal or Morocco: a coastline with some of the richest fishing grounds in West Africa, a mining sector anchored by the state-owned SNIM’s iron ore exports, and now, as of a project that reached commercial reality in 2025 after roughly a decade of development, a genuine offshore gas industry.

The Greater Tortue Ahmeyim (GTA) field sits directly on the maritime border between Mauritania and Senegal, developed by a consortium led by BP alongside Kosmos Energy and the two countries’ national hydrocarbons companies, SMH and Petrosen. First gas flowed at the end of December 2024, the first LNG was produced in February 2025, and the first export cargo left in April 2025, at what both governments have formally designated a National Project of Strategic Importance. Phase 1 has a nameplate capacity of roughly 2.7 million tonnes of LNG a year, and as of mid-2025 the partners were already in discussions over a second, larger phase. For a company in engineering, logistics, marine services, or professional services supporting the energy sector, this is a specific, dated, and still-developing reason to look at Mauritania now rather than a general pitch about African growth.

It’s worth being direct about what this does and doesn’t mean for the wider economy. Mauritania remains a low-income country by World Bank classification, and a single offshore gas project, however significant, doesn’t instantly transform the domestic business environment, administrative pace, or currency stability that a company will actually encounter day to day. The Ouguiya has a history of depreciation against major currencies, and a business budgeting in MRU should build in some flexibility around that rather than treating today’s exchange rate as fixed for the life of a contract.

Choosing the Right Business Structure

Because Mauritania’s company law comes from the OHADA Uniform Act rather than a bespoke national code, the structures on offer, and their underlying mechanics, will look genuinely familiar to anyone who has registered a company elsewhere in Francophone West Africa.

SARL (Société à Responsabilité Limitée)

The SARL is the standard vehicle for the large majority of foreign investors, permitting a single shareholder, foreign or Mauritanian, with liability capped at their contribution. The minimum share capital is MRU 1,000,000, roughly USD 25,000 at current exchange rates, and unlike some OHADA jurisdictions that allow this to be paid in over time, Mauritania generally requires it fully paid up and deposited before registration completes. This is a genuinely higher upfront capital commitment than some comparable West African markets, and it’s worth factoring into cash flow planning from the outset rather than discovering it partway through the filing.

SA (Société Anonyme)

An SA suits a larger operation, a joint venture with multiple institutional partners, or a business planning to raise capital or eventually list on the Casablanca Stock Exchange. It requires a minimum share capital of MAD 300,000, rising to MAD 3,000,000 where the company makes a public offering of its shares, and notarisation of the articles of association is mandatory. Regulated sectors, including banking, insurance and larger energy or infrastructure ventures, commonly use this structure given the governance and credibility it signals to institutional partners and regulators.

Succursale (Branch)

A foreign company can register a branch to execute a specific contract or project in Mauritania, common among contractors and service providers supporting mining or energy-sector clients on a defined engagement, without incorporating a new Mauritanian legal entity. This carries no separate legal personality, so liability for the branch’s activities flows back to the foreign parent, and it suits project-based work more than an open-ended local commercial presence.

Sole Proprietorship

A single individual can register as a sole trader, a route that’s fast, often completed within 48 hours through the Guichet Unique, and suited to a Mauritanian resident or someone already legally established in the country running a small operation. It carries unlimited personal liability and isn’t a practical structure for a foreign company seeking a distinct corporate identity.

Comparison of Common Business Structures in Mauritania

Structure Common purpose Pros Cons
SARL (société à responsabilité limitée) Foreign-owned subsidiaries, SMEs and standard commercial trading Minimum capital of MRU 1,000,000 (around USD 25,000); single-shareholder structure permitted; liability capped at contributed capital Capital must be fully paid up before registration, a genuine upfront cash commitment compared with some neighbouring OHADA states
SA (société anonyme) Larger operations, joint ventures, or businesses in regulated or capital-intensive sectors such as mining and hydrocarbons services Structure expected by banks, regulators and larger commercial partners for bigger projects Meaningfully higher minimum capital than a SARL; requires a board of directors and, in most cases, a statutory auditor
Succursale (branch of a foreign company) An existing foreign company extending a specific contract or project into Mauritania No new Mauritanian legal entity to build from scratch; keeps the parent company’s existing name and contracts No separate legal personality; the foreign parent carries full liability for the branch’s activities in Mauritania
Entreprise individuelle (sole proprietorship) A single Mauritanian resident or long-term resident running a small local operation Fast registration, often within 48 hours through the Guichet Unique; minimal capital formality Unlimited personal liability; not a practical route for a foreign investor wanting a distinct corporate entity

For most foreign investors building a genuine Mauritanian presence, the SARL is the practical starting point, provided the MRU 1,000,000 capital requirement is budgeted for as a real cash commitment rather than a formality. The SA, branch and sole proprietorship each suit narrower circumstances, scale, project-based work, or purely domestic small business respectively.

Mauritania's Legal and Regulatory Requirements for Companies

Registration itself runs through a single window, but a newly formed company still has separate, ongoing obligations to the tax authority and, once it hires staff, to the national social security fund, each requiring its own filing rather than happening automatically.

Key Business Regulations in Mauritania

  • Corporate income tax is 25% of net taxable profit, but every company also owes a minimum tax calculated as a percentage of turnover, cited by different professional sources as either 2% or 2.5%, payable whichever figure is higher than the profit-based calculation, so a business should confirm the currently applicable percentage with a Mauritanian accountant rather than assume a loss-making year produces no tax liability at all
  • VAT is charged at a standard rate of 16%, with specific higher rates applying to particular goods, 20% on petroleum products and 18% on telecommunications services, so a business in either of those sectors should apply the sector-specific rate rather than the general 16% figure
  • Beneficial ownership disclosure is required at registration, consistent with Mauritania’s anti-money laundering commitments, meaning the individuals who ultimately own or control a company need to be identified and recorded as part of the incorporation file, not just the immediate corporate shareholders
  • The p offers qualifying investors reduced taxation, lower municipal taxes and duty-free import of equipment, though accessing these incentives generally requires registering the specific investment with the relevant authority and, in some cases, meeting a minimum investment threshold
  • Certain sectors, mining and hydrocarbons chief among them, carry their own sector-specific licensing and local content requirements layered on top of standard company registration, so a business in these industries should treat the Guichet Unique filing as the starting point rather than the complete regulatory picture

Tips for Staying Compliant with Mauritania Laws

  • Confirm the exact minimum tax percentage currently in force with a local accountant before finalising financial projections, given the genuine discrepancy between sources citing 2% and 2.5% of turnover
  • Apply the correct sector-specific VAT rate for petroleum or telecommunications activity rather than defaulting to the general 16% rate
  • Prepare beneficial ownership documentation for the full ownership chain before filing, not just the immediate shareholder, since incomplete disclosure is a common cause of delay at registration
  • If pursuing Nouadhibou Free Trade Zone incentives, register the specific investment with the zone authority as a distinct step from standard company incorporation, and confirm the current minimum investment threshold directly rather than relying on older published figures
  • Budget realistic currency risk into any multi-year contract denominated in Ouguiya, given the currency’s history of depreciation against the US dollar and euro

Step-by-Step Process to Set Up a Company in Mauritania

Setting up a SARL in Mauritania runs through the Guichet Unique, a genuine one-stop shop that coordinates several formalities that would otherwise require separate visits to different institutions, though the sequence still has real dependencies worth understanding before starting.

1

Reserve Your Company Name

Check your proposed company name against the existing commercial register and reserve it through the Guichet Unique. This is a quick step, and it’s worth having a second or third name option ready in case your first choice is already registered.

2

Draft and Notarize the Company’s Statutes

Prepare the SARL’s articles of association, in French, setting out the company’s objects, capital structure, and management arrangements, then have them notarised by a Mauritanian notary. Foreign shareholders not travelling to Mauritania typically grant power of attorney to a local representative, often a lawyer or corporate service provider, to sign on their behalf, which is what makes remote incorporation genuinely possible.

3

Open a Bank Account and Deposit Share Capital

Open a provisional bank account with a Mauritanian bank and deposit the full MRU 1,000,000 minimum capital, obtaining the bank’s confirmation of deposit. Since Mauritania generally expects this capital fully paid up before registration completes, rather than allowing installment payment over time as some neighbouring OHADA states do, this step needs to happen with genuine funds in place, not a placeholder amount.

4

Submit the Complete Incorporation File to the Guichet Unique

File the notarised statutes, proof of capital deposit, identification documents for all shareholders and managers, and the beneficial ownership declaration with the Guichet Unique. Where documentation is complete, registration commonly takes one to two weeks for a SARL, longer than the 48-hour turnaround sometimes cited for a simple sole proprietorship, since a company filing involves more documents and a genuine review rather than a straightforward administrative entry.

5

Obtain Your Commercial Registration Certificate

Once approved, the company receives its registration with the Registre du Commerce et du Crédit Mobilier (RCCM), the OHADA-wide commercial registry, confirming the company’s legal existence. This certificate is what banks, government agencies and commercial counterparties will expect to see as proof the company genuinely exists.

4

Register for a Tax Identification Number

Apply to the Direction Générale des Impôts (DGI) for the company’s Numéro d’Identification Fiscale (NIF), the tax ID required for essentially all subsequent dealings with Mauritanian authorities, from filing returns to clearing goods through customs. This is a separate registration from RCCM incorporation, not an automatic follow-on step.

5

Register as an Employer with the CNSS Before Hiring

Before your first employee’s start date, register the company as an employer with the Caisse Nationale de Sécurité Sociale. This registration is tied specifically to having staff rather than happening automatically at incorporation, so a company that registers without immediate hiring plans can complete this step later, provided it’s genuinely in place before anyone actually starts work.

Hiring and Managing Employees

Mauritanian employment contracts must be written in Arabic and generally take an indefinite-term form as the presumed default, with fixed-term arrangements reserved for specific, justified circumstances. The standard working week is capped at 40 hours, typically spread across roughly 6.5 to 7 hours a day, and overtime carries a 150% premium on the standard hourly rate. The national minimum wage (SMIG) rose 12% from 9 April 2026, and currently sits at roughly MRU 4,000 a month, though sectors like mining and offshore fishing commonly negotiate their own, considerably higher wage scales under separate sectoral agreements, so a company hiring into either sector shouldn’t assume the national SMIG reflects the market rate it will actually need to pay.

Payroll runs on two separate tracks that are easy to conflate. Personal income tax, the Impôt sur les Traitements et Salaires (ITS), is progressive and can reach 40% at the top end, with a monthly exempt threshold currently around MRU 6,000, and it’s withheld and remitted by the employer monthly. Social security contributions to the CNSS sit on top of this and are structured differently: the employer’s share is commonly cited around 15% of gross salary, covering pensions, family allowances and occupational injury, calculated up to a salary ceiling that professional payroll sources currently place somewhere between MRU 7,000 and MRU 15,000 a month depending on which contribution component is being calculated, while the employee contributes a modest 1%. A separate health insurance scheme, the CNAM, adds a further employee-side contribution, commonly cited at 4% of salary. Taken together, a realistic budgeting range for total employer statutory on-costs is roughly 15% to 17% of gross salary, though the exact figure depends on where an employee’s salary sits relative to the various ceilings involved, which is worth confirming precisely with a Mauritanian payroll specialist rather than applying a single flat percentage across an entire workforce.

Foreign nationals need both an entry visa and work authorisation before starting employment, typically sponsored by the Mauritanian employer and processed through immigration and labour authorities together, with the specific route (short-stay work visa, longer residence permit with attached work authorisation) depending on the length and nature of the assignment. Given how much of the current hiring activity in Mauritania is concentrated in gas-sector-adjacent engineering, logistics and technical services, a company bringing in specialised foreign staff for a defined project should expect this process to run in parallel with, rather than after, the underlying commercial contract being finalised, since permit processing timelines are genuinely a factor in project mobilisation schedules right now.

Given how specialised much of the current demand is, technical and engineering roles tied to the gas sector, experienced mining-sector staff, bilingual Arabic-French professionals for government and corporate liaison work, a company may find that sourcing candidates is the harder problem to solve rather than the registration process itself. A recruitment partner with existing reach into Mauritania’s and the wider Sahel region’s talent pool can often close that gap faster than an in-house search, particularly for roles where the pool of qualified local candidates is genuinely thin.

Alternatively, for a company that wants to bring on staff in Mauritania without first completing SARL registration, capital deposit and CNSS setup, an Employer of Record in Mauritania can take on the legal employer role directly, managing ITS withholding, CNSS and CNAM registration, and Labour Code compliance while a company evaluates whether the market justifies a full local entity.

Financial Management and Reporting

Companies file monthly VAT returns, due by the 15th of the month following the reporting period, with late filings carrying a 10% penalty and non-filing a separate flat penalty. Income tax withholding filings are also due monthly, by the 15th, while CNSS social security contributions are generally remitted on a quarterly basis, a genuinely different cadence from the monthly tax obligations running alongside it, and worth tracking on separate calendars rather than assuming both follow the same schedule.

Annual financial statements must be filed with the RCCM in line with OHADA’s accounting framework, and an SA’s accounts generally require sign-off from a statutory auditor, a requirement a SARL doesn’t automatically carry unless its size or shareholder structure triggers it. A company operating in a sector with its own regulatory reporting, mining and hydrocarbons again being the clearest examples, should expect additional sector-specific financial disclosure on top of the standard OHADA filings, typically tied to the terms of its specific licence or production-sharing arrangement rather than general company law.

Common Pitfalls to Avoid

  • Assuming the SARL’s minimum capital can be paid in over time, when Mauritania generally requires it fully paid up before registration completes
  • Applying the general 16% VAT rate to petroleum or telecommunications activity, where sector-specific rates of 20% and 18% apply instead
  • Treating a loss-making year as automatically tax-free, when the minimum tax based on turnover still applies regardless of profitability
  • Benchmarking wages against the national SMIG for mining or offshore fishing roles, where sectoral wage agreements typically set considerably higher rates
  • Underestimating currency risk on multi-year Ouguiya-denominated contracts given the currency’s depreciation history

Tips for Operating Successfully in Mauritania

Treat the OHADA framework as a genuine advantage rather than an obstacle, particularly if your business already operates elsewhere in Francophone West Africa, since the underlying company law, accounting standards and commercial registry structure are shared across the region rather than unique to Mauritania. A legal or accounting team with Senegal, Côte d’Ivoire or Mali experience will find much of Mauritania’s corporate framework immediately familiar.

Separate your gas-sector-adjacent planning from your general Mauritania planning, since these are genuinely different opportunities with different timelines. The GTA project’s Phase 1 is operating and its Phase 2 remains under negotiation as of this writing, so a business betting heavily on Phase 2 activity should treat that as a distinct, not-yet-confirmed opportunity rather than build it into a base-case plan the way Phase 1’s already-operating capacity reasonably can be.

Finally, build realistic administrative timelines into any project schedule rather than assuming Mauritania’s one-stop-shop registration process means everything else moves at the same pace. Registration itself is genuinely fast for a market of this size, but foreign worker permits, sector-specific licensing, and banking relationships for a newly established foreign-owned entity have all been reported as taking longer in practice than the headline registration timeline suggests, and planning around the slower of these processes rather than the fastest tends to produce a more realistic project schedule.

Common Mistakes to Avoid

  1. Underfunding the SARL capital deposit relative to the genuinely required MRU 1,000,000 fully-paid-up minimum
  2. Missing sector-specific VAT rates for petroleum and telecommunications activity
  3. Assuming the minimum turnover-based tax doesn’t apply in a loss-making year
  4. Using the national SMIG as a wage benchmark for mining or offshore fishing roles governed by their own sectoral agreements
  5. Treating CNSS’s quarterly remittance cadence as though it matched the monthly tax filing schedule
  6. Building a base-case financial plan around GTA Phase 2 activity before it’s actually confirmed
  7. Underestimating how long foreign worker permit processing can add to project mobilisation timelines

Why Now is the Right Time to Register a Company in Mauritania

The genuine, dated reason to look at Mauritania now is the gas sector’s arrival as an operating industry rather than a long-promised prospect. First LNG exports in April 2025, a project formally designated as strategically important by both host governments, and active negotiations over a larger second phase together represent real, current momentum for a country whose economy has historically rested on iron ore and fishing alone. Companies in marine logistics, technical services, engineering support and specialised recruitment have a specific, current reason to evaluate Mauritania that didn’t exist in the same form even two years ago.

The honest complement to that opportunity is that Mauritania’s broader business environment, currency stability, administrative pace outside the headline registration process, and the depth of specialised local talent, hasn’t been transformed overnight by a single offshore project. A company registering now should do so with a clear view of both the genuine, dated opportunity the gas sector represents and the more gradual, ordinary pace of change everywhere else in the economy, rather than assuming one automatically implies the other.

Frequently Asked Questions

Much of the process can be handled remotely through a power of attorney granted to a local representative, typically a lawyer or corporate service provider, who signs the notarised statutes and manages the Guichet Unique filing on the founders' behalf. The genuine practical sticking point is the bank account, since opening a Mauritanian account and depositing the required share capital often benefits from, and in some cases may require, an in-person visit or at least direct engagement with the bank's own verification process, so founders should confirm their chosen bank's specific requirements before assuming the entire process can be completed without anyone setting foot in the country.

No. OHADA harmonises the underlying company law, accounting standards and commercial dispute resolution framework across its member states, but it doesn't create a single company registration valid across borders the way an EU passporting regime might. A Mauritanian SARL wanting to genuinely operate in Senegal or another OHADA state would still need to register there separately, though the shared legal framework does mean the underlying company law concepts, and often the professional advisors familiar with them, translate more easily across the region than they would to a non-OHADA jurisdiction.

A change to the beneficial ownership structure generally needs to be reported to the relevant authority as an update to the company's file, since the original disclosure was based on the ownership structure at the time of registration rather than a one-time snapshot with no ongoing obligation attached. A company undergoing a share transfer or ownership restructuring should treat this reporting as part of the transaction itself rather than an afterthought, particularly given how central beneficial ownership transparency is to Mauritania's anti-money laundering commitments.

Each production-sharing arrangement in Mauritania's hydrocarbons sector typically includes local content and capacity-building commitments funded by the project operator, intended to support the development of local suppliers and skilled workers rather than offering a blanket tax incentive to any company in the supply chain. A business hoping to supply the GTA project or its contractors should engage directly with the operator's local content and procurement teams to understand current qualification requirements, rather than assume general Investment Code incentives automatically extend to hydrocarbons-sector subcontracting.

Yes. A branch is treated as carrying on taxable activity in Mauritania in essentially the same way a locally incorporated company would be, so it needs its own tax identification number, VAT registration where applicable, and the same monthly filing obligations described earlier in this guide. The absence of separate legal personality affects where ultimate liability sits, with the foreign parent, but it doesn't exempt the branch from Mauritania's standard tax administration requirements.
