🇲🇨Monaco company

Concept

Monaco is a sovereign principality of barely two square kilometres on the Mediterranean, squeezed between France and the sea. Companies are formed here for a base close to Western Europe and its private banks, and for a tax system that leaves most locally-run business untaxed on profit. The everyday vehicle is the SARL; larger or regulated ventures use the SAM. For a private client a Monaco company usually does one of three jobs:

• obtaining a Monaco residence permit (self-employment)
• registration and management of yachts under Monaco flag
• holding and managing international assets (real estate, shares, IP)

Where the tax system comes from

Monaco abolished personal income tax in 1869, and residents who are not French nationals still pay none. The corporate side arrived in 1963, when France pushed Monaco into a bilateral fiscal convention. Signed on 18 May 1963 after the Franco-Monegasque crisis of 1962, that treaty made French nationals who moved to Monaco — or could not show five years' residence there by 13 October 1962 — taxable in France, and it created a business-profits tax — the Impôt sur les Bénéfices, or ISB — for companies that earn 25% or more of their turnover beyond the principality. The personal-tax regime that sits alongside it is set out in Monaco: tax regime for residents.

So Monaco is not a flat zero on corporate profit. A company serving local clients pays nothing; a company built to invoice foreign markets can land squarely in the 25% ISB. Drawing that line is the practical core of structuring here, and it explains why a company is so often set up together with a Monaco residence permit for the people who run it.

Structure

A Monaco company has the following structural characteristics:

• at least 2 members with no upper limit for an SARL (since the 2025 reform, Law No. 1.573, a single member may form an SURL), or at least 2 shareholders for a SAM
• the SARL manager (gérant) must be a natural person, and a foreign manager who is not a member needs an authorisation to practise from the Direction du Développement Économique; a SAM has a board of at least two directors
• participants bear risks only within the limits of their contributions
• economic presence in Monaco required, including physical office

SARL or SAM

Two forms cover almost everything. The SARL (Société à Responsabilité Limitée) needs at least €15,000 of capital (cash contributions are paid up to that minimum at formation, the balance within 18 months), two or more partners — a single-member company is an SURL, with €8,000 minimum capital when its member is an individual — and a manager — the gérant — who must be a natural person; it is reserved for commercial activity and suits most trading businesses. The SAM (Société Anonyme Monégasque) is the joint-stock form, with €150,000 of capital, a board of directors and incorporation by ministerial decree, used for banks, larger groups and regulated business. Both give limited liability, but passive asset holding suits the SAM, whose object may be civil as well as commercial — a role Monaco shares with established European platforms such as Luxembourg.

The official company-forms table also lists two partnership forms without a statutory minimum capital. In an SNC, all partners are traders and are indefinitely, jointly and severally liable for company debts. An SCS has at least one active partner with that unlimited joint liability and at least one limited partner whose liability is capped at the contribution; a limited partner must not manage the company.

The authorisation regime

Nothing operates in Monaco without prior government authorisation. Each permit is granted for a named activity and tied to real premises, so there is no lasting nameplate option: as a rule a company needs commercial premises, a working office and genuine local management — an SARL may be domiciled at its manager's home or with a domiciliation company only for one year, renewable once — and an authorisation cannot be repurposed for an unrelated business. In practice this is Monaco's built-in substance requirement, and it puts the principality in the same frame as the broader economic substance rules that low-tax jurisdictions now apply.

Taxes

Monaco's low-tax reputation is real but specific. Individuals face no income tax, no capital-gains tax and no wealth tax, and the only corporate charge that matters is the ISB on business profits. Whether a company actually pays it comes down to one test — how much of its turnover is earned outside Monaco:

Away from the ISB the burden is light. VAT follows the French system at a standard 20%, there is no withholding tax on dividends, and individuals owe nothing on income, capital gains or net wealth. A Monaco company therefore works best when its profits are genuinely local, or when it serves as a holding vehicle rather than a cross-border trading hub. Monaco is not one of the ten platforms on the holding grid, and read against it the trade-off is clear: dividends leave without withholding, as they do from Cyprus, Malta or the UAE, but a Monaco holdco brings a treaty network of nothing like the depth the Netherlands (about 95 agreements), Luxembourg (80+) or Cyprus (about 65) put behind their exemptions, so dividends coming up from operating companies abroad bear whatever withholding their source state applies.

A short comparison shows the split: a Monaco SARL running a restaurant or a local estate agency bills Monégasque customers, keeps its turnover inside the principality and pays no corporate tax — only VAT and employer social contributions. A SARL set up to license software to clients across Europe earns most of its turnover abroad, so it falls into the 25% ISB and has to show real staff and premises to defend that base. Same vehicle, same town: the tax outcome turns entirely on where the customers are.

Compliance

Maintaining a Monaco company requires compliance with the following mandatory requirements:

• full accounting with preparation of annual financial statements
• audit: always for a SAM; an SARL appoints a statutory auditor (commissaire aux comptes) if its share capital exceeds €150,000 or if, for two consecutive years, it exceeds two of three thresholds — balance sheet total over €1,500,000, turnover excluding VAT over €2,500,000, more than 20 employees
• registration in the beneficial ownership register (RBE) and updating data upon changes
• registration in the Trade and Industry Registry (RCI), whose declared information must be confirmed every five years
• reporting: a company within the ISB files its return within three months of the financial year-end (by 1 April when the year is the calendar year); the SARL manager files the balance sheet and profit and loss account with the RCI each year, with a signed attestation

Transparency and the FATF grey list

The secrecy image is dated. Monaco maintains a register of beneficial owners (RBE) and exchanges financial-account information automatically under the CRS. In June 2024 the FATF placed Monaco on its grey list of jurisdictions under increased monitoring, and as of mid-2026 it remains there: at the June 2026 plenary the FATF assessed Monaco's action plan as substantially completed and scheduled an on-site visit — the final step before delisting. Since 5 August 2025 Monaco has also been on the EU's high-risk third-country list, under Commission Delegated Regulation (EU) 2025/1184, so banks apply enhanced due diligence to Monaco structures. For an owner this means tighter onboarding, source-of-funds questions and record-keeping, with no change to the headline tax rules. How these registers and automatic exchange work in practice is covered in UBO registers and the CRS overview.
