Since 1 January 2021, a British citizen who wants to earn a living in France as a freelancer, consultant, tradesperson or online seller is treated as a third-country national. European freedom of movement no longer opens the door, and the French administration applies to Britons the same framework it applies to Americans, Australians or Canadians: a long-stay visa before arrival, a residence permit that expressly authorises self-employed work, registration of the business on the single official window, and then French tax and social charges on the profits. Each step has its own office, its own timetable and its own appeal route, and a mistake at one stage can block the next. This guide explains the full sequence in plain English: which visa and which carte de séjour (residence permit) covers self-employment, what a British resident already in France must do to start a business, how to register as a micro-entrepreneur (the official name for the auto-entrepreneur scheme) and what it really costs, and how to challenge a refusal or a wrong bill. Every French term is explained the first time it appears, and every key rule is linked to its official source so you can check it yourself before you act.

I. How can a British citizen obtain the right to work self-employed in France after Brexit?

A. Which visa and residence permit does a British newcomer need for self-employed work?

The starting point is simple and strict. A British passport allows visa-free short stays in the Schengen area of up to 90 days in any 180-day period, but it gives no right to live in France and no right to work there. Any Briton who plans to settle in France and earn self-employed income needs a long-stay visa that authorises that activity, applied for at the French consulate covering the place of residence in the United Kingdom before travelling. The visa that matches this project is the long-stay visa de long séjour valant titre de séjour (a long-stay visa that acts as a residence permit for its first year, known by its initials VLS-TS) endorsed for self-employed activity, leading after one year to the one-year temporary residence card marked entrepreneur/profession libérale (entrepreneur / liberal profession). That card is the legal permission to run a business as an individual in France. The card itself is governed by the Code de l’entrée et du séjour des étrangers et du droit d’asile (the immigration code, universally called the CESEDA), whose official text on Légifrance sets out the categories of residence permits, their conditions and their renewal. Because the card is activity-specific, a British newcomer cannot lawfully arrive on a visitor visa, which expressly forbids work, and simply start invoicing clients while sorting out the paperwork later.

The consulate does not grant the visa as a formality. The file must show who you are, what you will do and how the project will support you. In practice the consulate expects a passport valid well beyond the planned stay, proof of address in the United Kingdom, a detailed business plan in French or with a French translation, evidence of professional qualifications or experience for the intended activity, proof of financial means sufficient to live while the business starts, and, depending on the activity, evidence of premises, professional insurance or registration with the relevant professional body. Regulated activities raise the bar further: health professions, legal professions, architects, accountants, estate agents and many building trades require recognised qualifications, registration with the French professional order or body, and sometimes a specific licence before the visa can be issued. The official visa wizard on france-visas.gouv.fr lists the supporting documents for each visa category and each consulate, and it should be treated as the checklist of record rather than any private relocation blog. Files are lodged through the visa application centre (TLScontact in the United Kingdom), biometrics are taken, and the application fee is paid there.

Three practical points decide many files. First, language and presentation matter more than applicants expect. A business plan drafted only in English, with United Kingdom market references, sterling-only figures and no analysis of French demand, French pricing and French charges, invites a refusal for lack of a serious establishment project. A plan that names French customers or French platforms, converts the figures into euros, budgets for French social charges and tax, and identifies the French insurance and premises position reads as a real settlement project. Second, financial means are judged on durability, not on a single bank balance on one day. Regular income, savings built over time and a credible first-year forecast carry more weight than a large transfer made the week before the appointment. Third, previous immigration history is checked. Overstays in the Schengen area, a refused visa that was never challenged, or a period of undeclared work in France discovered through any channel will all surface, and each needs a frank explanation with documents rather than silence.

Once the visa is issued, two validations must happen quickly after arrival. The VLS-TS must be validated online within three months of arrival, which triggers the medical examination by the Office français de l’immigration et de l’intégration (the French immigration and integration office, OFII) and, for most newcomers, the civic training and language elements of the Republican integration contract. Missing the three-month validation deadline can render the stay irregular, which then poisons the first residence-permit application. The second validation is economic: the business must actually start. A visa holder who never registers a business, never invoices and never declares income will struggle at renewal, because the préfecture (the state office in each département that issues residence permits, led by the préfet) renews the entrepreneur card only where the activity is real and the resources it produces are sufficient. Keeping the OFII certificate, the validation confirmation, the lease, the business registration and the first invoices in one file from day one makes the renewal file almost self-writing a year later.

One large exception must be stated clearly because it changes everything. British citizens who were lawfully resident in France before 31 December 2020 and hold a Withdrawal Agreement residence permit are on a separate track created by the Brexit Withdrawal Agreement and implemented in France by Decree n° 2020-1417 of 19 November 2020. A Withdrawal Agreement permit already carries the right to exercise a professional activity, employed or self-employed, without applying for the entrepreneur card. A person on that track who wants to start freelancing does not need a new visa and does not go back to the consulate; the task is registration of the business and affiliation for charges, covered in Part II below. Confusing the two tracks is one of the most common and costly errors in British files: newcomers sometimes apply for a Withdrawal Agreement permit years after the deadline, and long-settled Withdrawal Agreement holders sometimes apply unnecessarily for an entrepreneur visa that complicates a status that already allows self-employment. Identifying the correct track on day one saves a year.

B. What must a British resident already living in France do to start or add self-employment?

A British citizen already living in France on a different permit — for example a visitor card, a student card, an employee card, a family card or a Withdrawal Agreement card — does not start from the consulate queue. The question is whether the existing permit already allows self-employed work and, if not, how to change it. Withdrawal Agreement permits and most family permits already allow any professional activity, so the holder can register a business directly. Employee permits, student permits and visitor permits do not: a visitor card expressly forbids work, a student card allows only limited employed hours alongside study, and an employee card authorises the specified employed post, not a freelance business on the side. Running undeclared self-employed activity on any of these permits risks the renewal of the permit itself, quite apart from the tax and social-security consequences, so the status question must be settled before the first invoice.

The procedure for changing status is called changement de statut (change of status) and it runs through the préfecture of the place of residence, now mostly by online application on the official foreigners’ portal. The applicant asks for the entrepreneur/profession libérale card and files the same economic substance as a consulate applicant: business plan, qualifications, financial means, and, for regulated activities, the professional registration. The difference is the standard of proof. Inside France, the préfecture examines not only the viability of the project but the coherence of the whole residence history: continuous lawful residence proved by permits and address evidence, genuine activity or study under the previous permit, tax returns filed and tax paid, and no period of irregular stay. A student who completed the degree, a visitor who can show a year of genuine non-working residence with sufficient means, or an employee whose contract ended cleanly with payslips and attestations to prove it, presents a coherent story. An applicant with gaps in residence, undeclared work or unpaid tax presents the opposite, and the refusal will say so.

Refusals of a change of status are discretionary but they must be reasoned, and the reasons dictate the remedy. French administrative law requires unfavourable individual decisions to state the legal basis and the facts behind them, a guarantee set out in Article L211-5 of the Code des relations entre le public et l’administration, and a refusal that merely recites a formula without engaging with the documents can be attacked on that ground alone. The classic refusal reasons in entrepreneur files are an unviable or undocumented project, insufficient financial means, qualifications that do not match a regulated activity, and, for visitors, an application that looks like an attempt to bypass the consulate route without any prior genuine residence. The remedy runs in two lanes. The applicant can file a recours gracieux (a request asking the préfet to reconsider) and a recours hiérarchique (an appeal to the Minister of the Interior), which cost nothing and sometimes succeed where a missing document caused the refusal. In parallel, the applicant can appeal to the tribunal administratif (the administrative court) of the place of residence within two months of notification of the refusal, a deadline set by Article R421-1 of the Code de justice administrative. Where the refusal is paired with an order to leave France, emergency proceedings exist: the référé-suspension (urgent suspension application) under Article L521-1 of the Code de justice administrative can suspend enforcement while the court examines the case, provided urgency and a serious doubt about legality are shown.

Two traps deserve emphasis because they destroy otherwise good files. The first is working before authorisation. Any self-employed income earned while the permit forbids it, or while the change-of-status application is still pending without a receipt expressly authorising work, can be held against the applicant and can generate reassessments. The lawful sequence is authorisation first, registration second, invoicing third. The second trap is letting the existing permit expire during the procedure. Applications must be filed while the current permit is still valid, and every receipt (récépissé) and every deposit certificate (attestation de dépôt) must be kept and carried, because the right to remain during processing depends on proof of a timely, complete filing. An expired permit with no receipt is the fastest route from a business project to a removal order, and no business plan survives that.

Students and recent graduates have one additional path worth checking. France offers a specific residence route for young graduates and for innovative projects, including the passeport talent (talent passport) family of multi-year permits, which can cover founders of recognised innovative businesses and, in some configurations, self-employed professionals with a supporting opinion from the relevant ministry or public body. The eligibility thresholds, salary or investment levels and supporting opinions change regularly, so the current conditions should be verified on the official visa wizard and with the préfecture before building a file around them. For most British freelancers, consultants and tradespeople, however, the standard entrepreneur/profession libérale card remains the natural vehicle, and exotic alternatives should only be preferred where the file genuinely meets the published criteria rather than as a way around a weak business plan.

II. Once authorised, how do you register the business, pay the charges and fight a bad decision?

A. How do you register as a micro-entrepreneur and what tax and social charges apply?

Registration is the step newcomers most often misunderstand, because the United Kingdom has no equivalent of the French single window. Since 1 January 2023 every business creation, whatever the activity, must go through the Guichet unique (single window) operated by the Institut national de la propriété industrielle (the national industrial property institute, INPI) on formalites.entreprises.gouv.fr. Paper filings at the old activity-specific centres are gone. The founder declares identity, address, activity code, start date and, for the micro regime, the tax and social options, and the window routes the file to the tax office, URSSAF and the relevant social-security fund. The registration produces the SIREN number (the business identifier) and the SIRET number (the establishment identifier), without which no lawful invoicing is possible. A British founder needs a French address, a valid residence permit authorising self-employment, and, for regulated activities, the qualification or licence, before the window will complete the file. Starting to invoice while the file is still draft is undeclared work, with the full range of tax, social-security and criminal exposure that label carries.

The micro-entreprise regime itself is a tax simplification for small individual businesses, and auto-entrepreneur is simply its common name combined with simplified social-charge payments. Income tax is computed on turnover after a standard flat-rate allowance (abattement) that stands in for expenses: no detailed expense accounts, but also no deduction of real costs. For sales of goods, food to take away and accommodation, the allowance and the turnover ceiling sit in Article 50-0 of the Code général des impôts, which governs micro-BIC (industrial and commercial profits). For services and for liberal professions, the sister provision is Article 102 ter of the Code général des impôts, governing micro-BNC (non-commercial profits). In round terms the current triennial ceilings are about 188,700 euros for sales and about 77,700 euros for services, with allowances of 71 percent, 50 percent and 34 percent depending on the category. These figures are re-set periodically and the exact current ceilings and allowances should be verified against the Code général des impôts on Légifrance and the tax administration’s BOFiP commentary before any forecast is signed, because quoting last year’s ceiling in a business plan is an avoidable unforced error.

On top of income tax come the social charges, which are where British founders most often under-budget. A micro-entrepreneur pays a flat percentage of actual turnover each month or quarter to URSSAF (the body that collects social-security contributions), with nothing due where turnover is zero. Indicative recent rates are around 12.3 percent for sales of goods, around 21.2 percent for commercial services and around 21 to 23 percent for liberal professions depending on the pension fund, plus a small contribution for professional training. These percentages are set by regulation and move, so the only safe figure for a forecast is the one produced by the official URSSAF simulator on urssaf.fr on the day the plan is finalised. What matters legally is the principle: the percentage applies to gross turnover with no deduction for costs, which makes low-margin service businesses much more expensive in France than their founders expect, and the choice between monthly and quarterly declarations, made at registration, determines the rhythm of cash collection for the whole year. Late declarations trigger surcharges automatically, and persistent non-declaration triggers estimated assessments that are painful to unwind.

Three options and obligations around the core regime complete the cost picture. First, the versement libératoire (a flat-rate final payment of income tax, operated through Article 151-0 of the Code général des impôts) lets a founder pay income tax as a small additional percentage of turnover alongside the social charges — about 1 percent for sales, 1.7 percent for commercial services and 2.2 percent for liberal professions — instead of adding the profits to the household’s progressive tax return. It is only available below a household-income ceiling and it is irrevocable for the year once chosen, so the choice must be modelled against the household’s total French taxable income, including any United Kingdom pension or rental income declared in France, rather than ticked by default. Second, value added tax: the franchise en base (the small-business VAT exemption) in Article 293 B of the Code général des impôts releases small turnovers from charging and recovering VAT, but the thresholds are among the most frequently amended figures in French tax law and must be checked in the current text, not in last year’s guide. A founder who exceeds the threshold without noticing becomes a VAT collector retroactively, which is an unpleasant discovery. Third, the cotisation foncière des entreprises (the local business tax, CFE), due under Article 1447 of the Code général des impôts, is payable from the second calendar year of activity even by a consultant working from a spare bedroom, subject to a minimum base set by the municipality. Paris and inner-suburb minimum bases are high enough to surprise newcomers who assumed a home office meant no local business tax.

The cross-border dimension adds one more layer that is specific to British founders. A self-employed person working physically in France is, as a rule, subject to French social-security legislation and pays French charges even while keeping British nationality, British clients and a sterling bank account. The European coordination rules that once made this automatic within the European Union no longer cover the United Kingdom in the same way, and the applicable instrument is now the social-security protocol attached to the EU-United Kingdom Trade and Cooperation Agreement, combined with French domestic affiliation rules. The leading illustration of why affiliation matters remains the Court of Justice’s decision of 26 February 2015 in case C-269/13 de Ruyter, published on Curia and on EUR-Lex, which held that social levies earmarked for the French social-security system could not be imposed on persons already subject to the social-security legislation of another Member State. The fact pattern there concerned capital income, not self-employment, but the principle it defends — one applicable social-security legislation at a time, proved by the portable document reporting affiliation — governs every dispute in which a British founder is asked to pay twice or claims an exemption. Detached-worker certificates, certificates of coverage and proof of actual affiliation should be obtained before the dispute, not after the assessment.

Finally, the United Kingdom side of the ledger does not disappear. A British citizen resident in France who keeps United Kingdom clients normally declares the worldwide self-employed profits in France as the state of residence and claims treaty treatment in the United Kingdom for the same income, with the France-United Kingdom double-tax treaty allocating taxing rights and the foreign-tax-credit or exemption mechanics preventing full double taxation. Practical compliance means keeping two coherent sets of records: French quarterly or monthly turnover declarations, French annual return with the professional annexes, and United Kingdom self-assessment pages that mirror the same underlying figures with the treaty claim attached. Figures that differ between the two returns without explanation are the single most common trigger for a French audit of a British file, and reconciling them before filing is cheaper than explaining them afterwards. Our broader analysis of British remote work from France, covering tax residence, payroll and social security for employees, is set out in our remote-work guide for Britons employed by United Kingdom businesses, and the companion guide to correcting a late or wrong French return is our Form 2047 correction guide.

B. How do you challenge a visa refusal, a registration block or a wrong URSSAF or tax bill?

Refusals and wrong bills in this field come from four different offices, and each has its own challenge clock. Treating them as one generic appeal is the error that loses cases. The four tracks are the consulate for visas, the préfecture for residence permits, URSSAF and the social-security funds for charges, and the tax office for income tax, VAT and CFE. The evidence overlaps — identity, residence, business reality, turnover — but the addressee, the form and the deadline differ, so the first step on receiving any adverse decision is always the same: read the Citations of legal basis and remedies printed on the decision itself (voies et délais de recours), diary the shortest deadline shown, and work backwards from it.

Visa refusals follow the consular track. The refusal form states whether the decision can be challenged before the visa appeals board, the commission de recours contre les décisions de refus de visa (the board that hears challenges to visa refusals, CRRV), sitting in Nantes, and in standard practice the challenge to the board within two months of the refusal is the route that preserves the later appeal to the tribunal administratif (administrative court) in Nantes if the board rejects or stays silent. The file to the board must do what the consulate file did not: answer each stated or inferable ground with documents. Where the ground is an unconvincing project, add French market evidence, letters of intent from French clients, a revised euro forecast with charges budgeted, and proof of premises or insurance. Where the ground is insufficient means, add six to twelve months of bank statements showing the build-up of savings, not a single recent deposit. Where the ground is a security or prior-overstay issue, add the explanation with supporting records. A bare letter repeating the original application adds nothing and is routinely rejected. Because consular refusals for long-stay business visas are often terse, the CRRV stage is also the moment to request, politely and precisely, the fuller reasons, relying on the administration’s duty to state reasons recalled above.

Residence-permit refusals by the préfecture follow the domestic administrative track. The refusal letter must state the reasons and the remedies, and the standard response combines a free recours gracieux to the préfet and a recours hiérarchique to the Minister of the Interior with a court appeal to the local tribunal administratif within two months of notification under the Article R421-1 deadline cited above. The court appeal, not the gracious appeal, is what stops time running, so where the deadline is tight the court filing comes first and the amicable request follows. The most winnable préfecture cases are refusals based on a factual error — turnover misread, a missing renewal page, a qualification wrongly classified — or on a legal error, such as applying the employed-work rules to a self-employed file or demanding a document the regulations do not require. The hardest cases are discretionary assessments of project viability, where the court reviews manifest error rather than substituting its own business judgement; those are won with new economic evidence, not with adjectives. Where the refusal arrives with an obligation to leave France (obligation de quitter le territoire français, OQTF), the removal order has its own shorter deadlines and its own detention of enforceability rules, and emergency suspension under Article L521-1 should be assessed within days, not weeks.

URSSAF and social-security disputes follow the social track, which is unforgiving on deadlines. The sequence typically runs from contribution notices to a formal demand (mise en demeure), then to an enforceable collection order (contrainte). The mise en demeure should be answered on the merits immediately with turnover printouts, registration certificates and affiliation evidence, because silence at that stage hardens into an enforceable figure. The contrainte can be opposed before the tribunal judiciaire (the civil court, social division) within a short deadline counted in days — fifteen days from service in the standard case — so a contrainte received by post must be opened, read and diaried the same day. Alongside the court route, a claim to the commission de recours amiable (the friendly-settlement board, CRA) of the fund allows a documented, cost-free review that resolves many computation errors without a hearing. The recurring British-specific errors to check before paying are affiliation to the wrong fund (commercial versus liberal-profession schemes), application of the wrong rate to the wrong turnover category, estimated assessments raised for quarters where turnover was actually zero but never declared, and social charges levied despite a valid detachment or coverage certificate placing the founder under United Kingdom legislation for the period. Each of these is proved by paper — fund affiliation letters, quarterly declaration receipts, nil returns, coverage certificates — which is why the monthly discipline of declaring, even nil, matters more than any argument made afterwards.

Tax disputes follow the fiscal track, which is slower but highly procedural. An income-tax reassessment, a VAT demand or a CFE bill is challenged first by a written claim (réclamation) to the tax office, filed within the statutory window — in the standard case, by 31 December of the second year following the tax year or the collection event — setting out the facts, the legal basis and the exact relief sought, with every supporting document attached. The administration has six months to answer; silence then counts as rejection and opens two months to appeal to the tribunal administratif. The micro-regime generates its own classic disputes: turnover reclassified from sales to services or the reverse with the wrong allowance applied, the versement libératoire unwound because the household-income ceiling was exceeded, VAT applied retroactively after an unnoticed threshold crossing, and CFE minimum bases applied by a municipality the founder never identified as the place of business. Each turns on records the founder either kept or did not: dated invoices with correct VAT mentions, threshold-tracking tables, household tax notices proving the income ceiling, and the CFE notice itself. A preventive rescrit (a formal ruling request asking the administration to confirm the tax treatment of a described situation) costs nothing but care in drafting and, once issued in the founder’s favour, binds the administration on the facts disclosed. Founders who expect a borderline year — a threshold crossing, a mixed sales-and-services activity, a first year straddling two countries — should consider a rescrit before the return, not a réclamation after the assessment.

Across all four tracks, the evidence file that wins is assembled the same way. Identity and residence: passport, current permit or visa with OFII validation, proof of continuous address, and, for Withdrawal Agreement holders, the Withdrawal Agreement card. Business reality: Guichet unique registration certificate with SIREN/SIRET, professional qualifications and registrations, insurance certificates, lease or domiciliation contract, client contracts or letters of intent, and a coherent euro forecast showing charges. Financial truth: business bank statements, quarterly or monthly URSSAF declaration receipts including nil returns, French tax returns and assessments, and the matching United Kingdom returns with treaty claims. Procedural proof: every decision with its envelope or electronic notification stamp, every receipt for every filing, and a dated log of appointments, calls and submissions. Present the file to each office as if the reviewer knows nothing about the other three offices, because that is usually true. And never let a deadline pass while waiting for a document: file the challenge in time on the evidence available, then supplement it, since French limitation rules revive almost no missed appeal.

Conclusion

A British citizen can absolutely build a self-employed life in France after Brexit, and hundreds do every year, but the project succeeds in a fixed order that cannot be rearranged. First the right to work: the correct visa and the entrepreneur/profession libérale card for newcomers, or a verified existing permit that already allows self-employment for residents, with Withdrawal Agreement holders on their own simpler track. Then the business itself: registration through the Guichet unique, the micro-entreprise options chosen on modelled figures rather than default ticks, VAT and CFE positions checked in the current texts, and social charges budgeted at French rates on gross turnover. Then the discipline that protects both: declaring every period including nil ones, keeping French and United Kingdom figures reconciled, and keeping every permit, receipt and assessment in a single file. Refusals and wrong bills are part of the landscape, not the end of the project, and each has a defined challenger, a defined clock and a defined evidence set — the consular board and the Nantes court for visas, the préfet, the minister and the local administrative court for permits, the CRA and the judicial court for charges, the tax office and the administrative court for tax. The founders who prevail are rarely those with the most original business idea; they are those whose file answers the reviewer’s next question before it is asked.
