Monaco. The name alone conjures images of superyachts, casinos, and zero income tax. But what if you’re not parking a hundred million in a trust just yet? What if you’re a freelancer, consultant, or small operator who wants to set up shop in the Principality without the overhead of a full corporation?
Good news: Monaco allows sole proprietorships. They call it Entreprise Individuelle or Activité en nom propre. It’s the simplest legal form you can operate under here. No shareholders, no board meetings, no corporate veil. Just you, your skills, and the Monaco administration watching closely.
Let me walk you through what this actually means in practice.
What Is an Entreprise Individuelle in Monaco?
It’s a sole proprietorship. You and the business are legally the same entity. Your personal assets are on the line if things go south. No limited liability shield here.
This structure works for:
- Consultants
- Freelancers
- Small traders
- Service providers
But here’s the catch: you need to be a Monaco resident to operate as an Entreprise Individuelle. That means you need a residency permit, which in turn means proving financial self-sufficiency (think €500,000+ in a Monaco bank, or roughly $540,000). Monaco doesn’t hand out residency like candy.
Once you’re in, registration is straightforward through the Service des Activités Économiques. They’ll want proof of your address, your business plan, and depending on your activity, professional qualifications or permits.
The Tax Reality: It’s Not All Sunshine
Let’s address the elephant in the room. Monaco has no personal income tax. For most residents, that’s true. Your salary, dividends, capital gains? Untouched.
Unless you’re French.
French nationals living in Monaco are still subject to French income tax under a bilateral treaty from 1963. If you hold a French passport, Monaco’s zero tax rate doesn’t apply to you. That’s a brutal exception, and it’s why you’ll see plenty of French entrepreneurs incorporating elsewhere or renouncing citizenship if they’re serious.
For everyone else: zero personal income tax on your sole proprietorship profits. But don’t pop the champagne yet.
Corporate Income Tax (ISB): The 25% Monaco Doesn’t Advertise
Monaco has a corporate income tax called Impôt sur les Bénéfices (ISB) at 25%. It applies if your sole proprietorship generates 25% or more of its turnover from activities outside Monaco.
Read that again.
If you’re a consultant billing clients in London, New York, or Dubai for more than a quarter of your revenue, Monaco considers that “foreign income generation” and hits you with the 25% rate. This is where Monaco’s tax haven reputation gets murkier. You’re only tax-free if you’re serving the local market, which is tiny (39,000 people). Most sole proprietors will trigger this rule unless they’re running a local shop or Monaco-focused service.
Social Security: The Fixed Cost You Can’t Avoid
Monaco has mandatory social security for self-employed individuals. You pay into two systems:
- CAMTI (health insurance)
- CARTI (pension)
These are not income-based. They’re fixed quarterly contributions, regardless of whether you earn €10,000 or €500,000.
| System | Quarterly Contribution (EUR) | Annual Total (EUR) |
|---|---|---|
| CAMTI (Health) | €1,101 | €4,404 (~$4,755) |
| CARTI (Pension, minimum) | €550.08 | €2,200.32 (~$2,375) |
| Total Minimum | €1,651.08 | €6,604.32 (~$7,130) |
That’s your floor. Around €6,600 per year ($7,130) just to exist as a sole proprietor in Monaco, even if you make zero revenue. CARTI can increase depending on your income bracket, but the base is non-negotiable.
Compare this to jurisdictions where social security is zero or optional for low earners. Monaco forces you to pay upfront. It’s a small price for access to excellent healthcare and a pension system, but it’s still a cost.
VAT: The 20% You’ll Probably Owe
Monaco applies VAT (Taxe sur la Valeur Ajoutée) at 20%. Same rate as France, because Monaco is part of the EU customs territory via France.
But there’s a relief valve: the Franchise en base de TVA. This is a small business VAT exemption. If your turnover stays below a certain threshold, you don’t charge VAT and you don’t file returns.
The exact threshold isn’t published in the data I’ve audited, but in France (which Monaco mirrors closely on VAT), it’s around €37,500 for services and €85,000 for goods. Monaco likely uses similar figures. If you qualify, it’s a huge administrative relief. No VAT filings, no quarterly reconciliations.
Once you cross that line, you’re in the VAT system. You charge 20% on invoices, deduct VAT on expenses, and file quarterly. Standard EU-style compliance.
Who Should Use This Structure?
The Monaco sole proprietorship makes sense if:
- You’re already a Monaco resident (or planning to become one)
- You’re not French
- Your turnover is modest (under the VAT exemption)
- Most of your clients are in Monaco or you can structure to keep foreign revenue below 25%
It’s a terrible fit if:
- You’re French (go corporate, go offshore, or renounce)
- You need liability protection (use a SARL instead)
- You’re earning high six figures (the lack of income tax is offset by the 25% ISB if you have foreign clients)
The Hidden Trap: Substance Requirements
Monaco is tiny, but it’s not stupid. If you’re billing $500k a year to clients in the US while living in a studio in Fontvieille, the authorities will ask questions. Monaco expects substance. That means:
- You actually live there (not just on paper)
- You conduct business activities from Monaco
- You can prove it (contracts, office, utility bills, travel records)
Fail the substance test, and your home country’s tax authority might claim you’re tax resident there instead. Monaco won’t fight that battle for you.
Practical Next Steps
If you’re serious about this, here’s what I’d do:
Step 1: Get residency sorted first. You can’t register a sole proprietorship without it. That means proving funds, securing a lease, and applying through the Section de la Résidence.
Step 2: Model your tax exposure. Calculate whether the 25% ISB applies based on your client base. If most of your income is foreign, a Monaco sole proprietorship might cost more than a Dubai freezone company or a Estonian e-Residency setup.
Step 3: Register with the Service des Activités Économiques and enroll in CAMTI/CARTI. Budget the €6,600+ annual social cost from day one.
Step 4: Track your turnover for the VAT exemption. Stay under the threshold if possible. Once you cross it, hire a local accountant. Monaco’s administration is efficient, but compliance is non-negotiable.
Final Word
Monaco’s sole proprietorship is elegant if your business fits the local model. You pay nothing in income tax (unless you’re French), but you’re locked into mandatory social security and possibly the 25% ISB if you serve foreign clients.
It’s not a magic bullet. It’s a tool. Use it correctly, and Monaco delivers on its reputation. Use it wrong, and you’ll pay more than you would in a traditional corporate structure elsewhere.
