Since 1 January 2021, a British citizen who wants to move to France and earn a living as a freelancer, consultant, tradesperson or independent professional is treated exactly like any other non-EU national. There is no British shortcut. You need a long-stay visa before you travel, a residence card that authorises self-employed work once you arrive, a proper business registration, and the discipline to pay French social charges and tax from the first euro of turnover. Each of these steps has its own refusal risk, and each refusal has its own remedy. This guide walks through the whole chain in the order you will meet it: the entrepreneur visa and the entrepreneur/profession libérale card, the file that proves your activity is viable, the micro-entrepreneur regime and its bills, the requalification trap that catches one-client freelancers, and how to challenge a refusal, a tax bill or an order to leave. Keep this guide alongside your file: the rules below change slowly, but your deadlines, once missed, do not forgive.
I. Getting the Right to Work for Yourself in France After Brexit
Before Brexit, a British freelancer could simply arrive, register a business and start invoicing. That world is gone. Today everything starts at the French consulate in London, months before the move, and the single most important document in your file is the one most applicants prepare last: the proof that the business will actually pay your living.
A. Which Long-Stay Visa and Which Residence Card Open Self-Employed Work
French law makes the starting point brutally simple. The first issue of a temporary or multi-year residence card is, as a rule, conditional on producing a long-stay visa. Article L. 412-1 of the Code de l’entrée et du séjour des étrangers et du droit d’asile provides, in its own words: “Sous réserve des engagements internationaux de la France et des exceptions prévues aux articles L. 412-2 et L. 412-3, la première délivrance d’une carte de séjour temporaire ou d’une carte de séjour pluriannuelle est subordonnée à la production par l’étranger du visa de long séjour mentionné aux 1° ou 2° de l’article L. 411-1.” In plain English: no long-stay visa, no card. A British citizen who enters visa-free for ninety days and then tries to regularise as a freelancer has built the file backwards, and the préfecture is entitled to say so. The British government’s own Living in France guide says the same thing from the London side: check the visa rules before you travel, because the ninety-day visa-free allowance is for visits, not for settling and working.
For a self-employed newcomer, the relevant card is the temporary residence card marked entrepreneur/profession libérale. Article L. 421-5 of the same code defines the beneficiary in one dense sentence: “L’étranger qui exerce une activité non salariée, économiquement viable et dont il tire des moyens d’existence suffisants, dans le respect de la législation en vigueur, se voit délivrer une carte de séjour temporaire portant la mention « entrepreneur/ profession libérale » d’une durée maximale d’un an.” Three cumulative conditions sit inside that sentence, and each one is a potential refusal ground. The activity must be non-salaried, meaning genuinely independent rather than disguised employment. It must be economically viable, meaning the figures add up. And it must provide sufficient means of existence, meaning you can live on it in France while respecting French law, including the rules of any regulated profession.
The card is temporary and lasts one year at most, which means renewal is part of the strategy from day one: at renewal, the préfecture re-examines viability and resources, so the first year’s accounts are already the next file. Two neighbouring routes are worth understanding so you can rule them out properly. If you are highly qualified and hold a job offer, the talent routes may fit better, but they require salaried employment and an employer sponsor, which is the opposite of freelancing. If your project is innovative and supported by a recognised French organisation, the passeport talent for business creation exists, but the recognition and investment thresholds make it a different product for a different profile. For the ordinary British consultant, designer, translator, coach, IT contractor or tradesperson, the entrepreneur/profession libérale card is the standard vehicle, applied for first as a long-stay visa at the consulate and then converted into the card at the préfecture after arrival and registration.
One terminological point that confuses many Britons: profession libérale does not mean what “liberal profession” suggests in English. It covers regulated and unregulated intellectual and care professions exercised independently, from architects and private nurses to consultants and translators, while artisans and traders fall under parallel craft and commercial registration logic with their own qualification requirements. A British electrician, plumber or builder cannot simply declare the trade: craft activities require proven professional qualification, and the file must evidence diplomas or experience that the French authorities accept. Check the official English-language page for the entrepreneur/profession libérale card on service-public.fr early, because it lists the supporting documents the administration will actually ask for, and preparing them in London is far cheaper than preparing them after arrival.
B. The Viability File: Business Plan, Means and the Refusals You Must Pre-empt
The consulate and then the préfecture decide viability on paper, so the paper must be serious. The service-public guidance asks for, among other things, a business plan and a multi-year budget, and states the governing test in plain terms: the project must be economically viable and must provide sufficient livelihoods. Concretely, a convincing file contains a narrative business plan identifying the clients, the market, the pricing and the ramp-up period; a multi-year budget with turnover, costs and drawings that reconcile with each other; any signed letters of intent, draft contracts or pipeline evidence; proof of the qualifications or experience the activity requires; and bank or funding evidence showing you can live in France while the turnover builds. Each element answers one of the three statutory conditions in article L. 421-5, and a file that is strong on the project but silent on personal means, or strong on savings but vague on clients, invites a reasoned refusal.
The standard refusal formulas track the statute: activity not demonstrated to be economically viable, means of existence insufficient, or documentation too thin to assess either. A refusal can also rest on regulated-activity grounds, for example where the applicant proposes to exercise a protected profession without the required French authorisation or registration. Because the card lasts only a year, think of the refusal risk in two waves: the visa refusal in London, which stops the project before travel, and the card refusal or non-renewal at the préfecture, which leaves you lawfully present only until your current document expires. Both must be challenged quickly, and the remedies are examined in the second part of this guide.
British applicants face two practical handicaps worth naming. First, qualifications and track records earned in the United Kingdom must be translated and explained: a UK portfolio, Companies House history or HMRC record proves experience, but only if the decision-maker can read it and connect it to the French project, so certified translations and a short explanatory note are money well spent. Second, the exchange rate and the cost of French social charges, examined below, must already appear in the budget: a plan priced in pounds with no charge line for URSSAF contributions reads as a plan written for another country. Where members of the family travel with the entrepreneur, their own long-stay visas and subsequent cards follow the family route rather than piggybacking on the business card, so spouses and children need parallel files, and school, health cover and housing evidence should be consistent across all of them. Readers coming to the visa question for the first time may also consult our general guide to long-stay visas and cartes de séjour for British newcomers, which covers the common refusal and removal mechanics shared by all routes.
II. Running the Business Once Admitted: Registration, Tax, Charges and Remedies
Admission is the residence half of the project. The business half starts at registration and continues, every month or every quarter, through declarations and payments. France makes starting simple and continuing expensive: the micro-entrepreneur regime, the former auto-entrepreneur scheme, lets you register quickly and pay charges as a proportion of actual takings, but the rates, the income-tax mechanics and the requalification risk for one-client contractors must be understood before the first invoice, not after the first reassessment.
A. Registering as a Micro-Entrepreneur and Paying French Tax and Social Charges
Registration comes first because everything else hangs off it: without registration there is no SIRET number, no professional account history for the renewal file, and no lawful basis for issuing French invoices. Declarations are filed online through the official business formalities portal, and the choice of activity code and legal framing at this stage determines the tax and social-charge category that follows. A consultant who registers under the wrong heading can spend a year paying the wrong contributions and then face a painful regularisation, so the registration step deserves the same care as the visa file. Keep every certificate the portal returns: the préfecture will want them at renewal, and the tax office will want consistency between the registered activity and the declared income.
Most British freelancers start under the micro-enterprise tax regime, which taxes a flat-rate portion of turnover rather than real profit. Article 50-0 of the Code général des impôts sets the entry thresholds on the previous or penultimate year’s turnover: “203 100 € s’il s’agit d’entreprises dont le commerce principal est de vendre des marchandises” and “83 600 € s’il s’agit d’autres entreprises”, the latter covering services and therefore most freelance work. The same article fixes the taxable result as turnover minus a standard allowance: 71 per cent for sales-based activities, 50 per cent for other activities, and 30 per cent for certain furnished-letting activities, with the allowances never falling below 305 euros. The mechanism is deliberately rough justice: no deduction of real expenses, but no obligation to keep full accounts either. A service freelancer billing 60,000 euros is therefore taxed on 30,000 euros of deemed profit before the progressive scale or, where eligible and elected, the flat-rate withholding option. Whether the withholding election or the standard declaration suits you depends on your household income as a whole, which is why the first French tax return, with its forms 2042, 2047 and 3916 for foreign accounts, should be prepared as carefully as the visa file.
Social charges are the heavier bill and the one that shocks Britons used to National Insurance. Micro-entrepreneurs fall under the micro-social regime, and article L. 613-7 of the Code de la sécurité sociale describes the machinery: “Les cotisations et les contributions de sécurité sociale dont sont redevables les travailleurs indépendants” under the micro tax regimes “sont calculées mensuellement ou trimestriellement, en appliquant au montant de leur chiffre d’affaires ou de leurs recettes effectivement réalisés le mois ou le trimestre précédent un taux global fixé par décret pour chaque catégorie d’activité”. In practice this means you declare the takings actually received in the previous month or quarter, including zero, and pay a single percentage covering most social contributions and charges, with the rate set by decree per category of activity. You choose monthly or quarterly declarations at registration, missed declarations trigger penalties even for nil periods, and the contributions open health, maternity, pension and invalidity cover under the independent workers’ branch, which is the route by which most British freelancers access the French health system and eventually the carte Vitale.
Two refinements complete the picture. First, independent workers outside the micro-social option pay provisional contributions computed on earlier income, and article L. 131-6-2 of the Code de la sécurité sociale explains that contributions are calculated provisionally on the contribution base of the year before last, with a flat-rate base fixed by decree for the first two years of activity. A freelancer who leaves the micro regime or outgrows it therefore moves from pay-as-you-earn simplicity to provisional billing with year-end adjustment, and the cash-flow planning must change accordingly. Second, once you are resident in France, the France–United Kingdom double tax treaty of 19 June 2008 allocates taxing rights between the two countries so the same profit is not fully taxed twice, with a credit mechanism on the French side; the treaty does not exempt you from declaring, and British-source income keeps its own reporting obligations in France. Keep the treaty logic, the micro thresholds and the declaration calendar in one dashboard, because the préfecture, URSSAF and the tax office each read a different line of the same story at renewal time.
B. The Requalification Trap, URSSAF Reassessments and How to Challenge Every Refusal
The most dangerous legal trap for a British freelancer in France is not the visa queue but the single client. French law starts from a presumption that suits genuine independents: article L. 8221-6 of the Code du travail provides that registered independent workers “sont présumés ne pas être liés avec le donneur d’ordre par un contrat de travail dans l’exécution de l’activité donnant lieu à immatriculation ou inscription”. Registration therefore protects you, but only presumptively: where the working reality shows permanent legal subordination, courts reclassify the relationship as employment, with back pay, paid leave, employer’s charges and dismissal indemnities for the worker, and reassessment plus penalties on the client’s side. The test, repeated in decision after decision, is whether the person works under the authority of an engager holding the power to give orders and instructions, to control performance and to punish failings.
The Cour de cassation has applied that test to platform and contractor arrangements in terms every freelancer should memorise. In the Uber judgment of 4 March 2020, appeal no. 19-13.316, published in the Bulletin, the court endorsed the appeal judges’ finding, in the decision’s own words, that “le statut de travailleur indépendant de M. F… était fictif et que la société Uber BV lui avait adressé des directives, en avait contrôlé l’exécution et avait exercé un pouvoir de sanction”, and it rejected the companies’ appeal (Cass. soc., 4 March 2020, no. 19-13.316). Three years later, in a courier case that restated the doctrine for delivery work, the court recalled that “le lien de subordination est caractérisé par l’exécution d’un travail sous l’autorité d’un employeur qui a le pouvoir de donner des ordres et des directives, d’en contrôler l’exécution et de sanctionner les manquements de son subordonné”, quashing the appeal decision that had refused reclassification (Cass. soc., 27 September 2023, no. 20-22.465). A British IT contractor working full-time for one London or Paris client, following its hours, using its tools, forbidden from substituting or from working for others, and terminable at will, walks directly into this case law. Protect yourself structurally: several genuine clients, your own equipment and premises, freely set rates and schedules, the right to subcontract, and contracts that say so and mean it.
URSSAF controls are the second front. The agency can audit, reclassify hidden employment, and reassess contributions with surcharges, and its notices follow a formal adversarial procedure with deadlines that must be calendared on receipt, not at leisure. Never ignore a mise en demeure or a contrainte: each has its own short challenge window before a specific judge, and silence converts a contestable claim into an enforceable one. The same discipline applies to residence refusals. A visa or card refusal is challenged first by an informal or hierarchical appeal where available, then by an annulment action before the administrative tribunal, normally within two months of notification, with a reasoned decision letter to attack and your viability file as evidence. Where the refusal leaves you without any right of stay and removal is ordered, speed becomes everything: remaining without a valid title exposes you to an obligation to leave France, and article L. 611-1 of the Ceseda lists the cases, including the foreigner who “s’est maintenu sur le territoire français sans être titulaire d’un titre de séjour”, in which the administration “peut obliger un étranger à quitter le territoire français”.
Urgency has its own judge. Article L. 521-1 of the Code de justice administrative allows the interim-relief judge, seised alongside an annulment action, to suspend a decision “lorsque l’urgence le justifie et qu’il est fait état d’un moyen propre à créer, en l’état de l’instruction, un doute sérieux quant à la légalité de la décision”. For a freelancer whose card refusal destroys the business overnight, that suspension route, pleaded with evidence of viable turnover and paid contributions, is often more valuable than the annulment itself, because it preserves lawful presence while the main case is heard. Keep every refusal, every acknowledgment of receipt and every proof of posting: in administrative litigation the file that wins is the file that proves dates. And keep the business real in the meantime, because nothing persuades a tribunal like turnover declared, charges paid and clients who answer the phone.
Conclusion
A British freelancer can still build a working life in France after Brexit, but the project now runs on two parallel tracks that must never separate. The residence track starts in London with a long-stay visa, continues at the préfecture with the one-year entrepreneur/profession libérale card, and is renewed on proof that the activity is economically viable and provides sufficient means, exactly as article L. 421-5 requires. The business track starts with careful registration, continues through the micro-enterprise tax allowances and the monthly or quarterly micro-social declarations, and survives only if the independence is genuine in fact as well as on paper, because the requalification case law from Uber to the 2023 courier decision shows no mercy to fictitious self-employment. Budget the charges before you move, diversify the client base before the first renewal, calendar every administrative deadline, and challenge every refusal or reassessment within its window with the file to support it. Done that way, freelancing in France remains what it has always been for the well-prepared: demanding, formalistic, and entirely possible. Start the visa file in London, register correctly on arrival, invoice cleanly, declare honestly, and never let a refusal letter sit unanswered past its deadline.
