Self-Employment and Business Profits
A US citizen who operates as a freelancer, consultant, or business owner in France faces two overlapping treaty provisions. Article 14 governs independent personal services (professional activities performed without an employment relationship). Article 7 governs business profits of an enterprise operating through a permanent establishment.
Both provisions follow the same fundamental principle: income is taxable only in the residence state unless a fixed presence in the source state crosses the applicable threshold. For individuals, the threshold is a “fixed base regularly available” under Article 14. For enterprises, it is a “permanent establishment” under Articles 5 and 7.
For US citizens, the saving clause means US taxation applies regardless of how the treaty allocates taxing rights. The treaty structure determines what France taxes and therefore what foreign tax credit is available.
Article 14: Independent Personal Services
Basic Rule
Income from professional services or other independent activities of a resident of a contracting state is taxable only in that state, unless the individual performs activities in the other state and has a fixed base regularly available there. If a fixed base exists, only the income attributable to that fixed base may be taxed in the other state.
“Professional services” under Article 14 includes independent activities of physicians, lawyers, engineers, architects, dentists, accountants, and other professionals. It also includes scientific, literary, artistic, and educational activities performed independently rather than under an employment relationship.
The Fixed Base Test
A fixed base is a regular, available place where the individual habitually performs professional activities. Unlike a PE, which requires an “enterprise,” the fixed base test applies to individuals performing services as independent contractors or professionals.
What constitutes a fixed base:
- A home office in France maintained and regularly used for client work
- A rented studio, workshop, or office space in France
- A professional consulting office maintained in France
- A dedicated workspace in France used on a recurring basis
What does not constitute a fixed base:
- Occasional use of a hotel room or shared workspace while traveling
- A temporary work arrangement in France for a single short-term project
- Use of a client’s facilities without a separate available workspace
The critical factor is regularity and availability. A freelancer who visits France twice a year for client meetings does not have a fixed base. A freelancer who maintains a French office and performs the majority of their work there does.
Attribution of Income
Only the income attributable to the fixed base may be taxed by France. If a US freelancer performs 40% of their work from a French office and 60% from a US location, France can tax approximately 40% of the income. The allocation is based on the activities attributable to the fixed base, which may require an analysis of client contracts, work product, and time records.
Article 7: Business Profits and Permanent Establishment
Business Profits: General Rule
Business profits of an enterprise resident in one contracting state are taxable only in that state. The other state may tax those profits only to the extent they are attributable to a permanent establishment located in that state.
Article 7 applies when the self-employed person or entrepreneur operates through an entity (a company, a registered enterprise) rather than as an individual providing services. For a US entrepreneur operating a French entity (SAS, SARL, or EURL), the French entity is itself subject to French corporate tax regardless of the treaty; the treaty’s PE analysis is relevant to the US entity’s exposure to French tax.
What Constitutes a Permanent Establishment (Article 5)
A permanent establishment is a fixed place of business through which the enterprise’s business is wholly or partly carried on. The treaty specifically includes:
- A place of management
- A branch
- An office
- A factory or workshop
- A mine, oil well, quarry, or other natural resource extraction site
The 12-month construction rule: A building site, construction project, or installation project is a PE only if it lasts more than 12 months.
Excluded activities (Article 5(4)): A fixed place maintained solely for the following does not constitute a PE:
- Storage, display, or delivery of goods
- Maintaining a stock of goods for processing by another enterprise
- Purchasing goods or collecting information
- Activities of a preparatory or auxiliary character
Dependent agent PE (Article 5(5)): Where a person other than an independent agent acts in a state on behalf of an enterprise and habitually exercises authority to conclude contracts in the enterprise’s name, the enterprise is deemed to have a PE in that state. This rule applies where an employee or representative based in France enters into binding commitments for a US enterprise.
Attribution of Profits to the PE
Only profits attributable to the PE are taxable by France. Attribution follows the separate-enterprise principle: profits are allocated as if the PE were a distinct and independent enterprise dealing at arm’s length with the head office. Expenses reasonably connected with PE activities are deductible, including expenses incurred elsewhere.
Interaction with French Business Structures
Micro-Entrepreneur
A US citizen operating as a micro-entrepreneur (auto-entrepreneur) in France is an individual conducting a professional activity with a fixed base in France. Article 14 applies. France taxes income attributable to the French activity. The income is also reported on the US return (Schedule C of Form 1040) and subject to US income and self-employment tax. The foreign tax credit is available on Form 1116 for French income taxes paid.
The micro-entrepreneur regime involves simplified French tax and social contribution treatment (abattement on revenue, flat-rate social contributions). For US tax purposes, gross revenue is reported and actual expenses may be deducted, creating a potential mismatch between the French and US tax bases.
SAS or SARL
A US citizen who forms a French SAS or SARL is the owner of a foreign corporation. The French entity is subject to French corporate tax (impôt sur les sociétés) on its French-source profits. The US citizen must assess whether the French entity is a controlled foreign corporation (CFC) for US purposes, which triggers Form 5471 filing obligations and potential Subpart F or GILTI inclusions.
The treaty’s PE analysis in this context pertains to whether the US entity (if any) is exposed to French tax through a PE. The French subsidiary is not itself a PE of the US parent; it is a separate taxable entity.
The Totalization Agreement: Income Tax vs. Social Contributions
The income tax treaty and the US–France Totalization Agreement are separate instruments addressing different obligations. The treaty governs income tax on self-employment profits. The totalization agreement governs social security contributions (cotisations sociales) on earned income.
A US citizen who is self-employed in France may owe French cotisations sociales on earned income regardless of how the treaty allocates income tax rights. The totalization agreement determines whether US or French social security coverage applies. A certificate of coverage from the US Social Security Administration can establish US social security coverage and exempt the individual from French mandatory contributions on earned income.
Treaty optimization cannot eliminate French social contribution obligations unless the totalization agreement’s coverage rules direct the individual to the US system.
Drafting Context and Evolving Guidance
Article 14 of the 1994 treaty (Independent Personal Services) follows the OECD Model Convention’s historical approach, which distinguishes between independent services (Article 14) and business profits (Article 7). The distinction hinges on whether the activity is carried on personally or through an enterprise structure.
The fixed base concept in Article 14 is analogous to but not identical with the PE concept in Article 7. The Technical Explanation for the 1994 Convention notes that the fixed base threshold is intended to apply to individual professionals in a manner similar to how the PE threshold applies to enterprises.
Article 14(4) includes a special rule: France may not exempt from French tax more than 50% of earned income from US partnerships accruing to a French resident. This provision prevents the use of US partnerships as a mechanism to shelve income in the US and claim a treaty exemption in France.
For US entities with employees working in France, the OECD commentary on remote work and PE creation (updated during the COVID-19 period) provides some administrative relief for temporary exceptional circumstances but does not create a permanent carve-out for ongoing remote work arrangements.
Frequently Asked Questions
Is a US freelancer working in France subject to French income tax?
Only if the freelancer has a fixed base regularly available in France. Under Article 14, income from independent personal services is taxable only in the freelancer’s residence state unless a fixed base exists in the other state. A US-based freelancer who performs occasional services in France without maintaining a regular work location there may not be subject to French income tax on those services.
What is a fixed base under Article 14?
A fixed base is a regular, available place where independent professional services are habitually performed. A home office in France used regularly, a rented workspace, or a professional studio maintained in France constitutes a fixed base. The test is similar to but distinct from the permanent establishment test under Article 7.
Does operating as a micro-entrepreneur in France create a fixed base?
Generally yes. A US citizen registered as a micro-entrepreneur in France and performing services there on an ongoing basis has a fixed base in France. France has the right to tax income attributable to that fixed base. The income is also subject to US taxation under the saving clause.
What is a permanent establishment under Article 5?
A permanent establishment is a fixed place of business through which an enterprise’s business is wholly or partly carried on. This includes offices, branches, workshops, and places of management. A construction site or project constitutes a PE only if it lasts more than 12 months.
Does the saving clause apply to self-employment income for US citizens?
Yes. The saving clause (Article 29) preserves US taxation of US citizens on worldwide income, including self-employment income. A US citizen operating a business in France owes both French taxes on French-source business income and US income and self-employment tax. The foreign tax credit mitigates double taxation on the income tax component.
How does the treaty interact with the totalization agreement for self-employed persons?
The income tax treaty and the totalization agreement are separate instruments. The treaty governs income tax on self-employment profits. The totalization agreement governs social security contributions on earned income. A US citizen self-employed in France may owe French cotisations sociales on earned income regardless of the treaty’s income tax allocation.
