Challenging French tax residence: tests, burden of proof and procedure

The tests of article 4 B: one is enough

Article 4 A of the French Tax Code taxes persons domiciled in France on their worldwide income and others on their French-source income only. Article 4 B defines domicile by alternative tests. Challenging French residence therefore means showing that none of them is met, or that the tax treaty ties you to the other State.

• The home. The place where you normally live and where the centre of your family interests lies, disregarding temporary stays elsewhere for professional or exceptional reasons. The Conseil d'État set aside a ruling that had inferred a home in France from the ownership of a house that had become the taxpayer's daughter's home, without examining where he normally lived; ruling itself, it held that the house, water and electricity consumption, subscriptions, a car and bank accounts in France were not enough, the house being occupied by a third party and the taxpayer showing a residence regularly occupied abroad (CE, 22 June 2017, no. 391379). Conversely, a family who stayed in France in principle fixes the home in France, even if the taxpayer works abroad for most of the year.
• The main place of stay. It applies only where there is no home. The administrative guidance generally treats a presence of more than six months in the year as the main place of stay, but this is not an absolute rule: the main place of stay may be in France if you spent clearly more time there than in each other country. The "183 days" are therefore neither a necessary condition nor a sufficient protection.
• Professional activity. You are domiciled in France if you carry on an activity there, as employee or self-employed, unless you show it is incidental. The main activity is the one to which you devote most effective time. Since the 2025 Finance Act (16 February 2025), executives of companies headquartered in France with turnover above €250 million are presumed to carry on their main activity there, unless proved otherwise.
• The centre of economic interests. The place of your main investments, the seat of your business, the place from which you administer your assets or from which you derive most of your income. It is the test most often raised against executives and investors who left France but kept their holding company, assets or dividends there.

These tests are explained, with case law on each, on our page on tax residence in France.

Three Conseil d'État decisions on contested residence

Residence disputes are argued with precise decisions. These three rulings fix the order of reasoning, the notion of home and the status of treaty resident.

• The order of review. The tax court first looks for the legal basis of the tax and its characterisation under national law, then compares it, of its own motion if need be, with the treaty (CE, Assembly, 28 June 2002, no. 232276, Schneider Electric). The treaty argument is therefore available in any event, but it does not dispense with discussing article 4 B.
• The home. A house kept in France, water and electricity consumption, subscriptions, a car and bank accounts are not enough to establish a home in France where the taxpayer shows a residence regularly occupied abroad and the house is occupied by a third party (CE, 22 June 2017, no. 391379). The court asks where the taxpayer normally lives, not what he owns.
• The treaty resident. Under the France / China treaty, resident status in a State depends only on being liable to tax there by reason of a personal link such as domicile or residence, whatever the extent of the tax liability (CE, 9 June 2020, no. 434972). The Conseil d'État thus rejects the idea that a taxpayer taxed in China on part only of his income cannot be resident there; he must, however, be liable to tax there by reason of domicile or a similar personal link, and not on the source of his income alone.

Who must prove what, and for how many years

• Adversarial reassessment: the burden is on the authorities. If you filed your return as a non-resident and the authorities send a reassessment proposal, they must establish that you were domiciled in France. In practice they rely on their rights to obtain information from banks, operators and foreign authorities.
• Ex officio assessment: the burden is on you. If you filed no return as a resident, the authorities may assess you ex officio (LPF art. L. 66). The thirty-day formal notice is not required where the taxpayer moved his domicile abroad without filing his income tax return (art. L. 67). It is then for you to prove the excessive nature of the tax, hence your residence abroad (art. L. 193). The same rule applies to an ex officio assessment following an adversarial examination of personal tax situation (art. L. 192).
• The limitation period. The authorities may reassess income tax until the end of the third year following the year for which the tax is due (LPF art. L. 169): for 2023 tax, until 31 December 2026. Since the 2025 Finance Act, the period is ten years where a person relies on a false tax domicile abroad, but only for the categories of income not included in any return filed within the statutory time limit: income declared in France as a non-resident remains subject to the three-year period. It is also ten years for income relating to a missed reporting obligation on foreign accounts, contracts or structures (CGI art. 123 bis, 209 B, 1649 A, 1649 AA, 1649 AB and 1649 bis C), except, for the accounts of article 1649 A only, where their balances never exceeded €50,000 in the year.
• What is added to the tax. Late-payment interest of 0.20% per month (CGI art. 1727); a 10% surcharge for late filing, 40% where the return is not filed within thirty days of a formal notice (art. 1728); a 40% surcharge for deliberate breach or 80% for fraudulent manoeuvres in case of understatement (art. 1729), which the authorities must always justify.
• Exit tax by ricochet. If French residence is maintained, there was no transfer of domicile: the exit tax declared on departure was not due, but all income comes within French tax, subject to the allocation and credits of the applicable treaty. Conversely, a genuine departure may trigger the exit tax and its 2074-ETD return. See our exit tax guide.

The procedure, from audit to court

• The audit. It often starts with a request for information or clarification, then a personal tax situation examination, in principle limited to one year. The written answers given at this stage set the ground of the debate.
• The reassessment proposal. You have thirty days to reply, extendable by thirty days on request made before the deadline. The reply discusses each article 4 B test, invokes the treaty and produces the evidence.
• Appeals before collection. Hierarchical appeal and referral to the designated contact: they often allow the residence question to be reviewed afresh before the position hardens. See hierarchical appeal and commissions.
• The claim. After collection, the claim is filed in principle until 31 December of the second year following the year of collection. A challenge to withholding tax on dividends must be filed by 31 December of the year following the withholding (LPF art. R*196-1). It may be accompanied by a request for a stay of payment, which suspends collection, with security above a certain amount.
• The tax court. If the claim is rejected, the administrative court, then the administrative court of appeal and the Conseil d'État. See our page on litigation before the administrative court.
• The mutual agreement procedure. If the other State also taxes you as a resident, the treaty opens a mutual agreement procedure between the two administrations, within a time limit specific to each treaty (for the France / United Kingdom treaty, three years from the first notification of the measure or six years from the end of the taxable year concerned). It may run in parallel with domestic litigation and must be prepared carefully, since it alone removes double taxation.

The evidence that convinces

The court reasons on dated and consistent facts. A foreign certificate of residence is useful but not enough: it attests liability to tax in the other State, not the absence of a home in France. The file is best built before any audit, year by year.
