What advantages does the impatriate tax regime offer?

France offers an attractive regime for people who come to work in France after having been tax domiciled outside France for the previous five years (article 155 B of the French General Tax Code (CGI)). It applies until 31 December of the eighth year following the start of employment.

  • Impatriation bonus: income tax exemption for the additional remuneration linked to relocating to France, for its actual amount or, subject to conditions, on a flat-rate basis (30% of net remuneration).
  • Work performed abroad: possible exemption of the portion of remuneration relating to stays abroad, where this work directly serves the interests of the employer established in France, within certain caps.
  • Foreign-source passive income: 50% exemption of certain investment income, income from intellectual or industrial property and capital gains on the sale of foreign securities.
  • IFI: in principle, until 31 December of the fifth year following the year of relocation to France, only real estate located in France is taken into account.

These advantages are subject to specific conditions and caps. On the social security side, exemptions from contributions may be available subject to conditions: they are assessed on a case-by-case basis. See also the tax impatriation page.

Expatriate or non-resident: what are your tax obligations in France?

It all depends on your tax residence, assessed according to the criteria of article 4 B of the CGI (home or principal place of stay, professional activity, centre of economic interests) and, where applicable, according to the relevant tax treaty.

  • French tax resident: you are in principle taxable on your worldwide income, from both French and foreign sources, subject to tax treaties.
  • Expatriate employee who remains resident: article 81 A of the CGI may exempt, subject to conditions, all or part of the salaries received for work abroad and certain expatriation bonuses.
  • Non-resident: you are in principle taxable in France only on your French-source income, for example rental income or real estate capital gains. Certain income is subject to withholding tax.

To learn more: tax expatriation.

How should you declare your foreign accounts and cryptocurrencies?

  • Foreign bank accounts: a French tax resident must in principle report each year, with their income tax return, accounts opened, held, used or closed abroad (form 3916-3916 bis). Non-residents do not have this obligation. The fine is in principle €1,500 per undeclared bank account, increased to €10,000 if the account is located in a State or territory that has not concluded with France an administrative assistance agreement giving access to banking information, and €750 per undeclared crypto-asset account (€1,500 where its value exceeds €50,000).
  • Cryptocurrencies: capital gains on disposals made by an individual are in principle declared on form 2086. They are exempt when total disposals for the year do not exceed €305. Above that threshold, they are in principle subject to the flat tax (prélèvement forfaitaire unique) of 31.4% (12.8% income tax and 18.6% social security contributions), unless the progressive income tax scale is elected. Accounts opened on foreign platforms are also in principle to be reported.

See also: foreign bank accounts.

How can you optimise your real estate capital gains?

  • Real estate capital gains: the main residence is in principle exempt. For other properties, holding-period allowances lead to an exemption from income tax after 22 years and from social security contributions after 30 years.
  • Property sold abroad: a French resident must in principle declare the capital gain in France. Depending on the case, the applicable tax treaty and the exemptions provided for by law may reduce, or even eliminate, the tax due in France.

Tax audit or reassessment: how can you defend yourself?

  • Tax audit: I advise and defend you from the outset of the procedure, in order to preserve your rights and, where possible, reach an amicable settlement with the tax authorities.
  • Proposed tax reassessment: you have 30 days to respond, a period that may be extended by 30 days on request (article L57 of the Tax Procedure Code (LPF)). The response, ideally prepared with your lawyer, generally aims to demonstrate that the adjustments are not justified and, where applicable, to establish your good faith.
  • Tax litigation: if the disagreement persists, a prior formal claim to the tax authorities is in principle mandatory before going to court. If it is rejected, I assert your rights before the competent court.

What I see in my cases

The audits I handle are desk audits, carried out from the tax authorities’ offices, and in-depth examinations of personal tax situation (ESFP), which compare the income declared with the taxpayer’s wealth and lifestyle. The question that comes up most often concerns the origin of the funds: depending on the answer given and the supporting documents produced, reassessments may be heavier or lighter, or even impossible. This shows how much care each answer deserves.

My practice is geared towards a good working relationship with the tax authorities and towards negotiation: in my experience, around nine cases out of ten are settled directly with them, one in ten going on to litigation (an order of magnitude, which does not prejudge the outcome of a given case). As a general rule, an audit takes six to twelve months, and litigation around two and a half years. The pages devoted to tax audits, proposed tax reassessments, tax reassessments and tax litigation detail what I observe at each stage.

Why use a tax lawyer?

  • Legal certainty: I help you meet your tax obligations and limit the risk of disputes with the tax authorities.
  • Optimisation within the law: I help you identify the tax schemes provided for by law that may apply to your situation.
  • Defence at every stage: from the tax audit through to the courts, I defend your interests.

FAQ

Am I taxable in France on my foreign income?

In principle, if you are a French tax resident, you are taxable on all of your income, including foreign-source income. The tax treaty concluded with the other State generally makes it possible to limit double taxation.

In principle, if you are a non-resident, only your French-source income is taxable in France.

Who can benefit from the impatriate regime?

The regime is aimed at people taking up work in France who were not tax domiciled there during the five years preceding the start of their employment. It applies until 31 December of the eighth year following the start of employment, provided they remain a French tax resident.

What are the risks of failing to declare a foreign bank account?

In principle, the fine is €1,500 per undeclared bank account, or €10,000 if the account is located in a State or territory that has not concluded with France an administrative assistance agreement giving access to banking information (€750 per undeclared crypto-asset account). As each situation needs to be analysed, a lawyer’s advice makes it possible to assess whether a voluntary regularisation may be appropriate.

How long do I have to respond to a proposed tax reassessment?

In principle, you have 30 days from receipt. This period can be extended by 30 days if you request it before it expires.

J'ai fait appel à Maître Uzan dans le cadre d'une procédure fiscale longue et techniquement complexe. Analyse rigoureuse du dossier, réponses précises dans des délais parfois très courts, et surtout une vraie capacité à maintenir un dialogue constructif avec l'administration plutôt qu'à durcir inutilement les positions.
Il a pris le temps de m'expliquer chaque étape et les options possibles, sans jargon et sans promesses excessives. Le dossier s'est conclu par une issue négociée.
Un accompagnement sérieux, du premier échange jusqu'au suivi complet de l'exécution. Je recommande sans réserve.

Grand professionnalisme - Une expertise précieuse
Nous recommandons chaleureusement Maître Marc Uzan. Après une première mauvaise expérience avec un autre cabinet qui nous demandait des honoraires exorbitants sans même connaître notre dossier, trouver Maître Marc Uzan a été un vrai soulagement.
L'approche est totalement différente, premier entretien téléphonique professionnel suivi d'un rendez-vous dans son cabinet et d'échanges de mails très fluides.
Ses précieux conseils et sa réactivité nous permettent d'avancer sereinement sur le dossier de succession des parents anglais de mon mari (biens en Angleterre).
Il nous guide parfaitement pour cette première étape et nous poursuivrons avec lui en toute confiance dans les mois à venir pour nos déclarations en France.

Je suis venu consulter Maître Uzan pour une question fiscale en apparence assez simple, mais qui me préoccupait depuis un certain temps. Il m'a apporté une réponse claire, précise et rassurante. Je recommande vivement cette consultation à toute personne ayant des interrogations fiscales: plutôt que de chercher pendant des heures sur Internet, il est beaucoup plus utile de consulter un professionnel. On obtient une réponse adaptée à sa situation, ce que internet ou l'IA ne peuvent pas fournir.

Google reviewJuly 2026

Je souhaite partager mon expérience avec Maître Uzan, que j'ai découvert en ligne sans recommandation préalable. La clarté de son site et la présentation de son expertise m'ont immédiatement inspiré confiance. Dès notre premier échange, j'ai été rassurée par son professionnalisme, sa qualité d'écoute et sa maîtrise des enjeux. Je lui ai donc confié un dossier complexe lié à des comptes à l'étranger. En l'espace de deux mois, la situation a été entièrement régularisée. Maître Uzan a su en assurer l'analyse, piloter l'ensemble des démarches, prendre en charge les formalités nécessaires et conduire les échanges ainsi que les négociations avec l'administration fiscale avec rigueur et efficacité, aboutissant à un résultat très satisfaisant. Dans la continuité, il est également intervenu sur ma déclaration fiscale 2025, traitée dans des délais particulièrement rapides, avec la même exigence. Réactif, disponible et précis, les échanges ont toujours été fluides et constructifs (par téléphone et mails).

Google reviewDecember 2025

J'ai eu la chance d'être accompagnée par Maître Uzan dans le cadre d'une succession internationale entre la France et les États-Unis, et je ne peux que le remercier chaleureusement pour son aide précieuse. Dans une période déjà émotionnellement difficile, il a su faire preuve d'une grande écoute, d'empathie et d'un professionnalisme irréprochable. Il a rendu compréhensibles des démarches fiscales complexes, en tenant compte à la fois des enjeux familiaux et des spécificités des deux systèmes (français et américain). Grâce à lui, tout s'est déroulé de manière fluide et sereine. Un avocat humain, compétent et engagé – je le recommande de tout cœur.

Google reviewOctober 2025

Il y a un an nous recevions un courrier du fisc sur des comptes étrangers. Après de nombreux échanges où nous avons donné au fisc tout ce qu'il demandait et montré notre bonne foi, rien n'y a fait. Il a fallu prendre un avocat et là comme par magie les choses ont été différentes...Il est bien dommage de devoir en arriver là pour faire valoir ses droits. En tout cas nous remercions Me Uzan pour son accompagnement et pour avoir trouvé un terrain d'entente avec le fisc, nous sommes soulagés que tout ca se termine.

Monsieur UZAN est un expert dans le domaine de la fiscalité, il maîtrise son sujet. Sa connaissance et son professionnalisme sont rares dans ce domaine. Merci.

Google reviewOctober 2024

J'ai bénéficié de conseils pertinents et précis au niveau de la fiscalité de mes activités; questions à propos desquelles je n'avais par ailleurs jamais trouvé de réponse. Je commençais à m'inquiéter car les enjeux étaient importants et il fallait que la situation s'apaise en se clarifiant. Tout est devenu limpide et je peux à présent avancer sereinement. Je recommande Me Uzan pour son professionnalisme et sa courtoisie.

Google reviewFebruary 2024

Nous avons eu la mauvaise surprise de recevoir une "proposition de rectification" (contrôle fiscal) en fin d'année. Après avoir essayé de discuter avec le contrôleur j'ai vite compris qu'il était indispensable de se faire accompagner par un avocat car il n'est malheureusement pas possible d'échanger de manière constructive en cas de contrôle. L'erreur était flagrante et Me Uzan a réussi à donner les bons arguments. Résultats: quasiment tout a été annulé. J'ai aussi fait appel à son expertise pour notre retour en France et il a été de très bons conseils.

La contrôleuse ne voulait pas entendre nos explications depuis plus d'un an et grâce à Maître Uzan le dossier a pu être clôturé rapidement.
