Mayotte. An overseas department of the European Union planted in the Indian Ocean, governed by French administrative law but with its own quirks. If you’re considering setting up a Société à Responsabilité Limitée (SARL) here—the local equivalent of a Limited Liability Company—you need to know what you’re getting into financially.
I’ve compiled the real numbers. Not aspirational marketing fluff, but the actual costs you’ll face in 2026 when incorporating and maintaining a SARL in Mayotte.
The Upfront Bill: What Company Formation Actually Costs
Let’s start with the sunk costs. These are one-time expenses you pay to get your entity legally registered and operational.
| Item | Cost (EUR) |
|---|---|
| Registry fees (Immatriculation au RCS) | €35.59 |
| Beneficial Owners Register (RBE) declaration | €20.34 |
| Mandatory Legal Notice (Annonce Légale) – 2025 Fixed Rate for Mayotte | €171.00 |
| Average Professional/Lawyer fees (Drafting statutes and legal assistance) | €800.00 |
| Total Sunk Costs | €1,026.93 |
So you’re looking at roughly €1,027 ($1,109) to get your SARL officially on the map. That’s the damage before you even open a bank account or hire anyone.
The Minimum Capital Trap
Here’s where it gets interesting. Technically, you can establish a SARL with a share capital of just €1. One euro. But here’s the kicker: it must be paid upfront.
This isn’t a cosmetic figure like in some jurisdictions where you can promise capital later. The cash needs to be there at formation. In practice, setting up a company with €1 in capital sends a terrible signal to banks, suppliers, and partners. You’ll struggle to open a corporate account, and you’ll look unserious.
My recommendation? Budget at least €5,000–€10,000 in actual share capital if you want to be taken seriously. The legal minimum is a trap for amateurs.
The Annual Burn: What Keeping Your SARL Alive Costs
Formation is one thing. Maintenance is where most people miscalculate.
A SARL in Mayotte is subject to French administrative requirements. That means accounting, filing, and local taxes—even if you make zero revenue.
| Item | Annual Cost (EUR) |
|---|---|
| Mandatory accounting services (Average for small SARL) | €1,800.00 |
| Annual accounts filing fees (Dépôt des comptes) | €45.02 |
| Minimum Business Property Contribution (CFE – Cotisation Foncière des Entreprises) | €240.00 |
| Minimum Annual Total | €2,085.02 |
That’s your minimum annual cost: around €2,085 ($2,252). And that assumes you have very simple operations. If your accounting is more complex, or you need additional filings, or your CFE base increases, you could be looking at €4,500 ($4,860) or more annually.
What You’re Actually Paying For
Accounting services: Not optional. French law mandates proper bookkeeping and annual accounts. You can’t DIY this unless you’re a qualified expert-comptable. The €1,800 figure is for a dormant or very low-activity company. Add transactions, employees, or VAT complexity, and this doubles quickly.
Filing fees: Every year, you deposit your accounts with the commercial registry (Greffe). It’s €45.02. Trivial, but mandatory.
CFE (Cotisation Foncière des Entreprises): This is the local business property tax. Even if you operate from home or a virtual office, you owe a minimum of €240. If you have a physical office, this scales with the rental value. It’s a wealth transfer to the local commune. You can’t escape it.
Hidden Costs and Gotchas
The numbers above are clean. Reality is messier.
Banking: Opening a corporate account in Mayotte can be painful. Expect account maintenance fees of €200–€500 per year, depending on your bank and transaction volume. Some banks will require you to maintain minimum balances or charge per-transaction fees.
Registered office: If you don’t have a physical address, you’ll need a domiciliation service. Budget €300–€600 annually for a mailbox and legal address.
Amendments: Change your statutes, add a shareholder, or modify your business purpose? Expect another round of legal notice publications (€171+) and registry fees (€200+). Each corporate change event costs money.
Social charges: If you’re a gérant (manager) taking a salary or dividends, you’ll owe French social security contributions. These can be brutal—up to 45% of your remuneration. Not included in the figures above, but absolutely material.
Is Mayotte Worth It?
Let’s be clear: Mayotte is not a tax haven. It’s a French department, which means French corporate tax (25% standard rate as of 2026), French labor law, and French bureaucracy. The SARL structure itself is solid—limited liability, flexible management—but you’re operating in a high-compliance, moderate-tax environment.
So why would anyone incorporate here?
If you’re doing business in Mayotte or in the Comoros region, it makes sense. You get EU legal framework with local presence. If you’re servicing EU clients and want an EU-registered entity without mainland Europe’s higher costs, Mayotte offers a slight discount—but you’re still paying €2,000+ per year minimum to keep the lights on.
For pure offshore asset protection or tax minimization? No. There are far better jurisdictions with lower costs, simpler compliance, and actual fiscal advantages. Mayotte is pragmatic if you need the specific geographic or legal positioning it offers. Otherwise, you’re just paying French prices in the Indian Ocean.
The Practical Path Forward
If you’ve decided Mayotte is the right fit, here’s what you do:
1. Draft your statutes carefully. Use a local professional. The €800 you pay upfront will save you thousands in amendment costs later. Get the shareholding structure, management rules, and capital contributions right the first time.
2. Budget realistically. €1,027 to start, €2,085 minimum per year. Add banking, domiciliation, and a buffer for unforeseen compliance costs. Plan for €3,500–€4,000 annually in total fixed costs for a small, simple SARL.
3. Understand your tax residency. Just because your company is in Mayotte doesn’t mean you are. If you’re tax resident elsewhere, that jurisdiction may tax your foreign company’s income anyway. Don’t assume incorporation alone solves your fiscal problems.
4. Keep pristine records. French authorities don’t mess around. Late filings, incomplete accounts, or sloppy beneficial ownership declarations trigger penalties and audits. Compliance is not optional.
Mayotte gives you a functional EU entity in a strategically interesting location. But it’s not cheap, and it’s not a shortcut. If your business model justifies the costs and the administrative overhead, the SARL structure will serve you well. If you’re chasing flags for the sake of it, look elsewhere.
I keep this data updated as regulations and fees change. The 2026 figures above are current as of now, but Mayotte’s administrative landscape shifts. Check back if you’re planning for 2027 or beyond.
