Foreigners in France: tax residence and taxes 2026

Quick answer. You become a French tax resident as soon as a single criterion of article 4 B of the French Tax Code is met: your home or main place of stay is in France, your main professional activity is carried out here, or your centre of economic interests is in France. The consequence is significant: taxation on your worldwide income, unless a tax treaty applies.

Moving to France, taking a management role here or setting up a company changes your tax situation far sooner than most people expect. Many expatriates believe they need a full year of presence or a specific residence permit to be taxed here. That is wrong. Tax residence is triggered by objective criteria, and one is enough. For a foreign director or an inbound employee, the stakes are concrete: residence determines the basis on which France taxes you, which returns you must file, and how to avoid being taxed twice.

This article separates the stable rules from the trade-offs decided case by case. For an overview of the available statuses, our expatriate, secondee or inbound decision matrix usefully complements this read.

Everything starts with article 4 B of the French Tax Code. You are deemed to have your tax domicile in France if you meet at least one of the following criteria:

1. Home or main place of stay in France. The home is where you usually live with your family. Absent a clear home, the main place of stay is used, generally assessed beyond 183 days of presence in the year.
2. Main professional activity carried out in France. If your main employment or corporate office is exercised here, the criterion is met, even if your family remains abroad.
3. Centre of economic interests in France. This applies where your French-source income exceeds your foreign income, or where your investments and activity are mainly managed from France.

The consequence is set out in article 4 A. A resident is taxable on worldwide income; a non-resident, only on French-source income.

How to actually determine your residence#

In mobility files, the classification is built item by item. Here is the method we follow:

1. Track your actual physical presence over the calendar year (diary, tickets, leases).
2. Locate your effective family home and main accommodation.
3. Identify where your main professional activity is carried out.
4. Compare your French-source income with your foreign income.
5. Check whether a tax treaty links France to your other country of attachment.

Domestic law may treat you as a French resident while another State also considers you its resident. This is common in the first year of settlement. Bilateral tax treaties then override domestic law and resolve the conflict through a cascade of tie-breaker criteria, applied in order:

• permanent home;
• centre of vital interests (personal and economic ties);
• habitual abode;
• nationality.

Treaties have a second role: avoiding double taxation, either through exemption in France or by granting a tax credit. They do not exempt you from filing; they prevent you from paying twice.

This is the most underused mechanism among executives and directors arriving from abroad. The article 155 B regime targets people not tax-domiciled in France during the five calendar years preceding their start of duties, recruited by a company established in France and transferring their domicile here.

What it offers:

• The inbound bonus is exempt from income tax, either for its actual amount or, on election, for a flat 30 % of net remuneration.
• The exemption applies until 31 December of the 8th year following the start of duties.
• The regime also exempts 50 % of certain foreign-source passive income and securities capital gains.

Two caps frame the benefit: at the taxpayer's choice, the total exemption is limited to 50 % of remuneration, or the portion relating to activity carried out abroad is limited to 20 % of taxable remuneration net of the bonus.

US citizens and US tax residents follow a unique logic: US taxation is based on citizenship, not residence. An American settled in France therefore keeps US filing obligations, in addition to French ones. In practice, this often means a FATCA filing and the FBAR report of bank accounts held outside the United States, alongside the French return.

The France-United States treaty avoids double taxation, but it does not erase double filing. We detail this point in our guide on FATCA and FBAR for dual nationals and expatriates. Support from an accountant and French CPA used to international files prevents blind spots between the two systems.

The first year of settlement is when most mistakes happen, because the status switches mid-year and both countries claim taxation. Our advice: fix the classification on arrival, document the date of domicile transfer, and immediately assess eligibility for the inbound regime. The latter cannot be recovered: if the entry conditions are not met at the start of duties, the benefit is lost for eight years.

The centre of economic interests. A director may spend fewer than 183 days in France and believe they are a non-resident, while most of their income, company or investments are attached here. This single criterion is enough to establish residence and therefore worldwide taxation. Holding structures and intercompany flows are particularly sensitive; our analysis of the France holding and EU subsidiary legal and tax stack illustrates these friction points.

A resident is liable to IFI on net worldwide real estate above EUR 1.3 million. But article 964 of the French Tax Code provides a relief that is often overlooked: new residents benefit from an IFI exemption on real estate located outside France for the first five years after settlement. For an international real estate portfolio, this window significantly changes the bill. If your project includes activity in France, anticipate it from the business creation phase.

• Residence is triggered by a single criterion: never reason solely in number of days.
• Check the applicable treaty before filing your first return, not after a tax adjustment.
• The inbound regime requires a start of duties with a company established in France: a purely foreign mandate does not qualify.
• US persons: do not confuse the absence of double taxation with an exemption from filing. Both sets of obligations coexist.

A foreign executive takes over a French subsidiary mid-year. He keeps a home in his country of origin and spends his weekends there. First reaction: declare himself a non-resident. On review, his main professional activity is carried out in France and that is now his dominant source of income. He is a resident from the start of duties, but he meets the inbound regime conditions. Properly classified from the outset, the file secures both his worldwide return and the exemption of the bonus.
