Monaco Tax Regime

Monaco is best known for the near-total absence of personal income tax on its residents, but the Principality operates a distinct and fully developed corporate profits tax alongside indirect taxation modelled closely on the French system, reflecting the 1963 Franco-Monegasque fiscal convention and customs union with France. Companies carrying on genuinely commercial or industrial activity in Monaco are, in principle, outside the profits tax net unless they derive a substantial share of their turnover from outside Monaco or from the licensing of patents, trademarks, literary or artistic property rights, in which case a 25% business profits tax (impôt sur les bénéfices, ISB) applies. Individuals resident in Monaco pay no personal income tax at all — with the long-standing exception of French nationals, who remain taxable in France under the bilateral convention notwithstanding their Monaco residence. Monaco has committed to implementing aspects of the OECD/G20 BEPS and Pillar Two framework as part of its broader alignment with international tax transparency standards, although its Pillar Two implementing legislation is narrower in scope than in EU member states given the small number of Monaco-headquartered groups above the relevant revenue threshold.

1.1 Sources

Primary legislation includes Sovereign Ordinance No. 3.152 of 19 March 1964 instituting the business profits tax (impôt sur les bénéfices), as amended, the 1963 Franco-Monegasque fiscal convention, and Monaco's VAT provisions applied under the customs and fiscal union with France.

1.2 Recent developments

Monaco has continued to strengthen economic-substance, beneficial-ownership and automatic-exchange-of-information standards in recent years, consistent with its exit from EU and OECD grey-list monitoring processes and its participation in the Common Reporting Standard. The Principality has engaged with the OECD Inclusive Framework on Pillar Two, and while the population of Monaco-based groups meeting the EUR 750 million consolidated revenue threshold is limited, in-scope groups face top-up tax exposure on Monaco profits taxed below the 15% global minimum where the 25% ISB does not apply (that is, principally profits currently outside the ISB net under the domestic-turnover test). Monaco's VAT rates and rules continue to track French VAT changes automatically under the fiscal union, including periodic rate and threshold adjustments.

2.1 Rates and residence

Monaco levies a business profits tax (impôt sur les bénéfices sur les sociétés, commonly abbreviated ISB) at a rate of 25% on companies whose activity is industrial or commercial in nature and that either (i) derive more than 25% of their turnover from operations carried out outside Monaco, or (ii) derive income from the licensing or exploitation of patents, trademarks, manufacturing processes, or literary and artistic copyrights. Companies that carry on their commercial or industrial activity substantially within Monaco, without material foreign-sourced turnover or IP-royalty income, fall outside the ISB and are not subject to a general corporate income tax — a position without a direct equivalent among Monaco's larger European neighbours. There is no separate concept of tax residence for ISB purposes distinct from where the taxable activity is carried on and the turnover/IP tests are applied.

Because the 25% rate applies only where the statutory thresholds are met, many Monaco-incorporated trading and services companies serving predominantly local or Monaco-based clientele are not subject to the ISB at all, while companies deliberately structured to earn royalty income or a majority of revenue from outside Monaco are squarely within scope. Groups should analyse the turnover mix and any IP-licensing income carefully every accounting period, since crossing the 25%-foreign-turnover threshold brings a company into the ISB net going forward.

2.2 Dividends and participation exemption

Monaco does not operate a codified participation-exemption regime of the EU type, reflecting the fact that most Monaco companies are outside the profits tax net entirely; for the minority of companies subject to the 25% ISB, dividends received from qualifying subsidiaries are, in practice and under administrative guidance, generally excluded from double taxation via mechanisms comparable to those used in France (Monaco's fiscal convention with France provides a framework for avoiding double taxation of intra-group flows). Capital gains realised by companies outside the scope of the ISB are not taxed, since there is no general corporate capital gains tax outside the ISB base; for ISB-liable companies, capital gains connected with the taxable activity are included in ordinary taxable profit at the 25% rate.

2.3 Income determination and deductions

For companies within the ISB, taxable profit is computed from commercial accounts prepared under Monaco's accounting rules (closely aligned with French accounting principles), adjusted for tax purposes. Ordinary business expenses incurred for the purposes of the taxable activity are deductible, including salaries, rent, and financing costs on arm's-length terms. Depreciation follows French-aligned rates by asset category, generally straight-line, with accelerated declining-balance methods available for certain qualifying industrial equipment. Losses computed under the ISB rules reduce taxable profit in the ordinary way (see section 2.5). Companies outside the ISB have no equivalent income-determination exercise for Monaco tax purposes, since their profits are simply not subject to the tax.

2.4 Interest limitation

Monaco does not impose an EU ATAD-style fixed-ratio interest limitation (Monaco is not an EU member state and is not bound by EU directives), reflecting both the narrow population of ISB-liable companies and the absence of a comparable large-scale corporate debt market within the Principality. Interest on related-party and third-party financing is deductible for ISB purposes where incurred on arm's-length terms for the purposes of the taxable activity, subject to the tax administration's power to disregard or recharacterise non-arm's-length or artificial financing arrangements under general anti-abuse principles.

2.5 Losses

Losses computed under the ISB may be carried forward against future ISB-taxable profits for a period aligned with the French-influenced administrative practice, generally without an annual percentage-of-income offset cap, allowing a loss-making ISB company to shelter future taxable profit fully once it returns to profitability. There is no loss carryback. Losses have no relevance to the many Monaco companies that never enter the ISB base in the first place, since they have no ISB taxable profit against which a loss carryforward could be used.

2.6 Group taxation

Monaco does not operate a formal group-relief or fiscal-consolidation regime for ISB purposes comparable to the French intégration fiscale or EU group-taxation systems; each Monaco company liable to the ISB is generally assessed on a standalone basis. Groups with multiple Monaco entities typically manage the interaction between ISB-liable and non-ISB entities through intra-group service and licensing agreements priced on arm's-length terms, being mindful that the turnover and IP-royalty tests in section 2.1 apply at the level of each individual company rather than on a consolidated group basis.

2.7 Controlled foreign companies

Monaco does not operate a codified CFC attribution regime under domestic law. Because the ISB itself already targets companies with substantial foreign-sourced turnover or royalty income, and because most Monaco holding and operating vehicles fall outside the ISB net altogether, Monaco's system does not need a separate mechanism to attribute low-taxed foreign subsidiary income back to a Monaco parent in the way EU ATAD jurisdictions do. Monaco-resident individuals and companies with foreign investments remain subject to the tax rules of the source jurisdiction and to information exchange under the Common Reporting Standard and bilateral agreements, including the Franco-Monegasque convention for French nationals.

2.8 Transfer pricing

Monaco applies an arm's-length standard to related-party transactions of ISB-liable companies, informed by principles consistent with the OECD Transfer Pricing Guidelines, and the tax administration may adjust profits where intra-group pricing departs from what independent parties would have agreed — a consideration that is particularly relevant to the turnover-mix and royalty tests that determine ISB liability in the first place. Monaco entities that are constituent entities of multinational groups within the OECD BEPS Action 13 country-by-country reporting threshold (consolidated group revenue of at least EUR 750 million) are subject to CbCR notification and information exchange under Monaco's international agreements, notwithstanding the small number of such groups headquartered in the Principality.

2.9 Incentives

Monaco's principal 'incentive' is structural rather than a targeted relief: the exclusion of purely domestically-trading companies from the ISB altogether, and the complete absence of personal income tax for non-French residents (section 3.1), together make the Principality attractive for holding, private-wealth and services structures with a genuinely Monaco-centred activity base. New businesses established in Monaco may benefit from reduced or exempt treatment in their early years under specific administrative provisions designed to encourage local business creation, subject to conditions on genuine activity and employment in the Principality. There is no separate patent or IP box regime; IP-royalty income is instead one of the two triggers that brings a company into the 25% ISB net rather than a source of preferential treatment.

2.10 Pillar Two

Monaco has engaged with the OECD Inclusive Framework's Pillar Two project and international minimum-tax standards, though the population of Monaco-headquartered or Monaco-resident groups meeting the EUR 750 million consolidated revenue threshold is small given the size of the Monaco corporate sector. Where an in-scope multinational group has Monaco constituent entities, the interaction between the 25% ISB (which exceeds the 15% GloBE minimum where it applies) and the many Monaco entities that fall entirely outside the ISB (and would therefore show a 0% effective rate for GloBE purposes absent the substance-based income exclusion or other adjustments) is the key modelling question: profits earned by non-ISB Monaco entities that are constituent entities of an in-scope group can attract top-up tax under a parent jurisdiction's Income Inclusion Rule or Undertaxed Profits Rule even though no Monaco domestic profits tax applies to that income. Groups with material Monaco operations should model this exposure explicitly rather than assuming Monaco's favourable domestic rules translate directly into a favourable GloBE effective tax rate.

2.11 Branch income and reorganisations

A Monaco branch of a foreign company is subject to the same ISB turnover and royalty tests as a Monaco-incorporated company, taxed at 25% on attributable profits only where the branch's activity meets the foreign-turnover or IP-royalty thresholds; there is no separate branch profits or remittance tax beyond the ISB itself where applicable. Reorganisations of Monaco companies — mergers, contributions of business and changes of corporate form — are administratively straightforward given the narrow tax base, and since most Monaco companies are outside the ISB and there is no general corporate capital gains tax outside that base, many reorganisations of non-ISB companies do not trigger a Monaco tax charge at all; ISB-liable companies should confirm the tax treatment of any reorganisation with the Monaco tax administration given the absence of a codified reorganisation-relief regime comparable to the EU Merger Directive.

3.1 Residence and rates

Monaco levies no personal income tax on individuals resident in the Principality, regardless of the source or amount of their income, with one long-standing and important exception: French nationals resident in Monaco remain subject to French personal income tax on their worldwide income under the 1963 Franco-Monegasque fiscal convention, as if they were resident in France, unless they can demonstrate Monaco residence predating 13 October 1957 (a grandfathering condition that in practice affects very few remaining taxpayers). Non-French nationals who establish genuine residence in Monaco — evidenced by a residence permit, a Monaco home available for their use, and the centre of their personal and economic interests — are not taxed on income by Monaco and are not automatically taxed by their country of prior residence provided they genuinely relocate and sever tax residence there under that country's own rules and any applicable tax treaty.

3.2 Capital income and real estate

There is no capital gains tax on the disposal of securities or other movable property by Monaco-resident individuals (other than French nationals taxed under the convention), and no tax on dividends, interest or other investment income received by non-French Monaco residents. Gains on the disposal of Monaco real estate are not subject to a Monaco capital gains tax as such, though notarial registration duties apply on the transfer itself (section 6.2). Rental income from Monaco or foreign real property is likewise untaxed for non-French Monaco residents, a position that, combined with the absence of a wealth tax, materially differentiates Monaco from every other continental European jurisdiction covered in this series.

3.3 Social security and payroll

Employees working in Monaco, including cross-border commuters resident in France or Italy who make up a substantial share of the Monaco workforce, are covered by the Monaco social security system (Caisses Sociales de Monaco), funded by employer and employee contributions at rates broadly comparable to the French social security system given the close economic integration between the two states. Contributions cover health insurance, family allowances, workplace accident insurance, retirement and unemployment insurance, with combined employer and employee rates typically representing a significant percentage of gross salary notwithstanding the absence of personal income tax itself. Employers withhold and remit social security contributions monthly; there is no wage tax withholding given the absence of a personal income tax base.

3.4 Inbound individuals

There is no inheritance tax on transfers between spouses or between parents and children under Monaco's inheritance and gift tax rules, though Monaco does levy inheritance and gift duties on transfers to more remote relatives and unrelated persons at rates that increase with the remoteness of the relationship (well above the rates applicable to direct-line transfers). There is no wealth tax and no exit tax for individuals relocating from Monaco, consistent with the general absence of a personal income tax base to protect. Individuals establishing Monaco residence should in parallel confirm the position under the domestic law and any applicable tax treaty of their prior country of residence, since ceasing tax residence elsewhere is a matter for that other jurisdiction's rules and is not automatically achieved simply by obtaining a Monaco residence permit.

Monaco does not levy withholding tax on dividends, interest or royalties paid to residents or non-residents, consistent with the narrow scope of the ISB and the complete absence of a personal income tax base for non-French residents. Monaco's treaty network is narrower than that of most European states, reflecting its historically limited need for double-tax relief given the absence of domestic withholding and the small ISB-liable population; the 1963 Franco-Monegasque fiscal convention is the most significant bilateral instrument, allocating taxing rights between Monaco and France (in particular for French nationals resident in Monaco) and addressing administrative cooperation, information exchange and mutual assistance in tax collection. Monaco has also concluded a number of tax information exchange agreements and limited double-tax treaties with other partners as part of its transparency commitments.

Because Monaco does not withhold tax on outbound payments, cross-border structuring involving Monaco entities is generally more concerned with the counterparty jurisdiction's withholding tax on payments into Monaco, and with whether a Monaco-resident individual's home country recognises the change of tax residence, than with Monaco-side withholding relief. Monaco exchanges information under the Common Reporting Standard and its bilateral agreements, and anti-abuse and substance expectations apply to Monaco holding and services companies seeking to rely on the Principality's favourable domestic rules or the limited treaty network.

5.1 General anti-abuse and substance

The Monaco tax administration may disregard or recharacterise artificial arrangements designed principally to circumvent the turnover and IP-royalty tests that determine ISB liability, or to artificially fragment activity to remain below the 25%-foreign-turnover threshold, applying a substance-over-form approach. Monaco has strengthened economic-substance and beneficial-ownership transparency in recent years as part of its exit from international grey-list and enhanced-monitoring processes, requiring Monaco companies — particularly holding and asset-management vehicles — to demonstrate genuine local administration, and requiring beneficial-ownership information to be maintained and made available to the competent authorities.

5.2 Exit taxation and disclosure

There is no exit tax on companies or individuals relocating from Monaco, consistent with the narrow ISB base and the absence of a personal income tax or general capital gains tax. Monaco participates in automatic exchange of financial account information under the Common Reporting Standard and cooperates with OECD and international bodies on country-by-country reporting exchange for in-scope multinational groups. Monaco is not an EU member state and DAC6-style mandatory disclosure of cross-border arrangements does not apply domestically in the EU form, though Monaco-linked structures used by EU-resident promoters or intermediaries can still trigger DAC6 disclosure obligations in the relevant EU jurisdiction.

6.1 VAT

Monaco applies value-added tax under the customs and fiscal union with France, so Monaco VAT law mirrors French VAT rates and rules closely and automatically. The standard rate is 20%, with reduced rates of 10% (certain restaurant and transport services), 5.5% (basic foodstuffs, books, energy-efficiency works) and a super-reduced rate of 2.1% (certain pharmaceuticals and press publications), tracking the French VAT schedule. Registration, filing and payment follow French-aligned procedures, with monthly or quarterly returns depending on turnover, and input VAT recoverable for taxed business activities. Because ISB liability and VAT liability are entirely independent regimes, a Monaco company can be a normal VAT-registered trader while remaining outside the ISB altogether.

6.2 Transaction, payroll and other taxes

Registration duties (droits d'enregistrement) apply to the transfer of Monaco real estate at rates that vary with the nature of the transaction and the relationship of the parties, typically in a range around 4.5%–7.5% for arm's-length sales, with different rates for gifts and inheritances depending on the degree of relationship. Employers bear the employer share of social security contributions described in section 3.3 rather than a separate payroll tax. There is no net wealth tax and no general stamp duty on securities transfers. Monaco levies specific business licence-style administrative charges on certain regulated activities (banking, gaming, real estate agency) rather than a general business tax on companies outside the ISB.

7.1 Filing, assessment and audit

The tax year for ISB purposes is generally the calendar year or the company's accounting year where it differs. Companies within the ISB file an annual return with the Monaco tax administration (Direction des Services Fiscaux) computing taxable profit and the 25% liability, with an advance-payment mechanism based on the prior year's assessed liability and a balancing payment on filing. Companies outside the ISB have minimal ongoing profits-tax filing obligations, though they remain subject to VAT, social security and beneficial-ownership reporting. Audits focus heavily on the turnover-mix and IP-royalty tests that determine whether a company falls within or outside the ISB, given the significant financial consequences of that determination, as well as on transfer pricing for related-party transactions.

7.2 Rulings, appeals and penalties

Taxpayers may seek clearance or guidance from the Monaco tax administration on the application of the ISB turnover and royalty tests to a proposed structure, which is common given the binary consequences of falling inside or outside the tax base. Appeals against ISB assessments proceed through Monaco's administrative and judicial courts. Interest and penalties apply to late-filed returns and underpaid ISB liabilities, with more serious sanctions for deliberate misclassification of a company's turnover mix to avoid ISB liability; French nationals disputing their liability under the Franco-Monegasque convention pursue remedies through the French tax administration and courts in respect of the French-law liability itself.

Because most Monaco companies are outside the ISB, the profits-tax filing calendar above applies only to the minority of companies meeting the foreign-turnover or IP-royalty thresholds; all Monaco businesses, however, remain subject to the VAT and social security calendars regardless of ISB status. There is no personal income tax return to file for non-French Monaco residents, simplifying individual compliance relative to almost any other jurisdiction in this series.

9.1 Entity choice

The société anonyme monégasque (SAM) is the principal vehicle for larger commercial and financial activities, requiring government authorisation to incorporate and a minimum share capital, while the société à responsabilité limitée (SARL) suits smaller trading businesses with lighter formation requirements. Civil companies (sociétés civiles) are commonly used for real estate and asset-holding purposes by resident individuals and families. Branches of foreign companies are available but, like locally incorporated companies, are tested against the same ISB turnover and royalty criteria to determine profits-tax liability. Government authorisation and background review of shareholders and directors is a standard feature of Monaco company formation, reflecting the Principality's emphasis on the character and substance of businesses established there.

9.2 Structuring and incentives

Businesses genuinely centred on Monaco — retail, hospitality, local professional services, and asset-holding vehicles for Monaco-resident individuals — can operate entirely outside the ISB provided the foreign-turnover and IP-royalty thresholds are not crossed, making careful monitoring of revenue mix a core compliance task rather than a one-off structuring exercise. Holding and family-office structures benefit from the absence of a personal income tax, wealth tax and (for direct-line transfers) inheritance tax for non-French residents, making Monaco a long-established base for private wealth alongside its commercial and financial services sector. Groups with material foreign-sourced turnover or IP income should plan for 25% ISB liability from the outset rather than assuming Monaco's favourable general reputation extends to their specific fact pattern.

9.3 Worked effective-rate illustration

A Monaco SAM providing licensing services derives EUR 2,000,000 of EBITDA, of which the royalty and foreign-turnover tests are met, bringing the company within the 25% ISB. Depreciation is EUR 200,000 and arm's-length interest expense is EUR 100,000, both fully deductible with no fixed-ratio limitation. Taxable profit is 2,000,000 − 200,000 − 100,000 = EUR 1,700,000. ISB at 25% is EUR 425,000, an effective rate of 425,000 / 1,700,000 = 25.0% on taxable profit. If the after-tax profit of EUR 1,275,000 is distributed to a non-French Monaco-resident individual shareholder, no further Monaco tax applies to the dividend, so the combined burden on distributed profits remains 25.0%. By contrast, an otherwise identical Monaco company earning the same EUR 2,000,000 EBITDA purely from local Monaco trading, with no material foreign turnover or royalty income, would fall entirely outside the ISB, giving a 0% Monaco profits-tax rate on the same pre-tax profit — illustrating how decisive the turnover-mix and royalty tests are to the ultimate effective rate.

9.4 Compliance

Expect VAT and social security compliance for all Monaco businesses regardless of ISB status, annual ISB filing and advance payments for the minority of companies within scope, beneficial-ownership register filings consistent with Monaco's transparency commitments, and — for the small number of in-scope multinational groups — Pillar Two GloBE information return obligations. Because ISB status turns on a turnover-mix and royalty test rather than a fixed election, businesses approaching the 25%-foreign-turnover threshold should monitor their revenue composition through the year rather than only at year-end, to avoid an unexpected change in tax position.
