Client Reviews
Très satisfait de l'accompagnement de cet avocat fiscaliste pour la régularisation de mes comptes à l'étranger. Professionnel, compétent et à l'écoute, il a su m'expliquer clairement les démarches et m'accompagner avec sérieux tout au long du processus. Je recommande vivement ses services !
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.
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).
Deux expériences très bonnes avec Maître Marc Uzan. Compétent, disponible et efficace. Tout a pu être réglé à distance dans deux affaires personnelles concernant le droit international (France -Allemagne). Visios, mails : échange courtois et précis. On a avancé très rapidement. Je recommande chaleureusement.
Excellent conseil, particulièrement réactif et très pédagogue. Je ne peux que recommander chaudement!
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.
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.
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.
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.
Maître Uzan a su apporter des réponses claires et rapides à mes questions. Sa réactivité et ses explications m'ont permis d'avancer sereinement dans mes affaires. Je le recommande vivement !
M. Uzan nous a accompagné durant près d'un an dans notre dossier de compte étranger. Il a été disponible et son expertise dans ce domaine nous a permis de traverser cette épreuve très stressante.

Frequently asked questions
What is a tax lawyer and what do they do?
A tax lawyer is a lawyer who devotes their practice to tax law. They assist individuals and businesses alike with every aspect of taxation, both in France and internationally.
Faced with complex and constantly changing tax rules, the tax lawyer ensures compliance with the legislation while seeking the best tax optimization strategies. The goal: to secure your procedures while reducing your tax burden as much as possible, within the legal framework.
They act both upstream (advice, planning, tax returns) and downstream, in particular in the event of a tax audit, to defend you before the tax authorities.
What are the advantages of hiring a tax lawyer in Paris?
Engaging a tax lawyer in Paris has many advantages, particularly in the event of a tax audit. From the very start of the procedure, it is essential to be assisted by an experienced professional who can defend you effectively and protect your rights before the tax authorities.
Your lawyer maintains a constructive dialogue with the tax authorities, while using every available legal remedy to reduce, or even cancel, tax reassessments.
But their role is not limited to litigation. They also assist you with all transactions involving tax issues, whether you are an individual or a business:
- Sale of a business,
- Regularization of foreign accounts,
- Transfer or sale of real estate abroad,
- Returning to or leaving France (tax impatriation or expatriation),
- Corporate restructuring,
- VAT management,
- Income tax returns, etc.
An experienced tax lawyer thus provides you with legal certainty, peace of mind and a tailored tax strategy, adapted to your personal or professional situation.
How do you choose a good tax lawyer in Paris?
Three criteria are important: the lawyer's experience in taxation, their specific areas of expertise and their availability.
A good tax lawyer must above all have substantial experience in taxation, and have practiced tax law for a long time.
Their specific areas of expertise must match your specific situation: our tax law firm in Paris has developed specific expertise in the following areas in particular: international taxation, tax audits, foreign accounts, impatriation, expatriation, sales of foreign property, RSUs, Management Packages "ManPack", stock options, free share awards.
What are the costs of Me Marc Uzan's services?
To provide complete transparency on fees, Me Marc Uzan favors fixed fees: a fixed amount is announced before the start of the engagement. If the fixed fees proposed to you are suitable, the engagement begins immediately. If not, things end there. There are therefore never any surprises when it comes to fees.
The amount depends on the specific situation and the engagement: it is set at the start of the engagement and, of course, subject to the client's prior agreement, so there will never be any unexpected additional fees.
For consultations lasting up to one hour (at the office, by video call or by telephone, as the client prefers), the fee is €250 including VAT (TTC).
Tax procedure or advisory matter: fixed fee, that is, a fixed amount agreed in advance with your prior consent. There will therefore never be any unexpected additional fees.
What are the differences between a tax lawyer and a tax adviser?
There are many differences, but three key elements clearly distinguish them:
A tax lawyer has completed full legal training, with recognized degrees in tax law, and regularly updates their knowledge. Their genuine expertise is validated by their admission to the Bar. This is not always the case for a tax adviser, whose training may vary more.
A tax lawyer is covered by professional liability insurance. In the event of a problem, the client therefore benefits from solid financial protection. This protection is not systematic with tax advisers.
A lawyer is bound by absolute professional secrecy. They are also subject to strict ethical rules, overseen by the Bar Association (Ordre des avocats). This guarantees the client complete confidentiality.
When should you consult a tax lawyer?
It is preferable to consult a tax lawyer upstream, as soon as a particular tax situation arises: sale of a property abroad, leaving or returning to France, reporting foreign income, opening accounts abroad, transfer of assets, etc.
But if a tax audit has already begun or in the event of a dispute with the tax authorities, it is also essential to be assisted from the very first stages in order to benefit from all the safeguards and avoid errors with serious consequences.
Does an individual really need a tax lawyer?
Yes, because individuals' tax situations are often more complex than they seem. A tax lawyer can assist you in many cases:
- reporting foreign income,
- holding bank accounts abroad,
- selling or buying real estate,
- international gifts or inheritance,
- returning to or leaving France,
- or tax regularization.
Being assisted by a lawyer allows you to secure your procedures, avoid errors, and benefit from advantageous tax schemes, while complying with the legislation.
Why should a business or a professional engage a tax lawyer?
Businesses and self-employed professionals face complex tax issues: VAT, corporate income tax, executive compensation, tax audits, and restructurings (mergers, sales, transfers…).
A tax lawyer provides in-depth expertise to secure transactions, avoid reassessments and optimize tax management in compliance with the law. In the event of an audit or a dispute with the tax authorities, they also defend you at every stage of the procedure.
What happens at a first meeting with Me Marc Uzan?
The first meeting allows a precise review of your tax situation. You set out the facts, any documents, and the questions you have.
Me Marc Uzan analyzes the information, advises you on the possible options (advice, regularization, litigation, etc.) and explains the next steps, as well as the cost of the engagement, where applicable.
The first meeting is a consultation, which is charged at €250 including VAT (TTC).
The consultation can take place at the office, remotely (video conference) or by telephone, as you prefer. It lasts up to one hour and leaves you with a clear view of the possible solutions.
What is the difference between a tax advisory engagement and a litigation defense engagement?
A tax advisory engagement consists of anticipating, organizing or optimizing a situation before any dispute arises: income tax returns, structuring of assets, expatriation, regularization of foreign accounts, etc.
A litigation engagement, on the other hand, comes into play when you are already facing a tax audit, a proposed tax reassessment (proposition de rectification), or a procedure before the tax authorities or the courts.
In both cases, Me Marc Uzan assists you rigorously, adapting his strategy to your situation.
My case is simple – do I really need a tax lawyer?
Even in apparently simple situations, errors or omissions can lead to significant tax consequences. Engaging a tax lawyer allows you to secure your procedures, verify that your situation is compliant, and sometimes benefit from advantageous tax regimes you might not have thought of.
If difficulties arise later, your lawyer can also act quickly through litigation, if necessary. It is better to seek advice from the outset, even for an apparently simple case, than to have to react urgently to the tax authorities.
