Starting a business in France involves more paperwork than most founders expect, and far less pain than the horror stories suggest. The machinery has been genuinely simplified in recent years: company formation now runs through a single online portal, and the French state has spent a decade actively courting foreign founders. What has not changed is that the system rewards preparation. Founders who understand how French entities, banking, and social charges work before they file move fast. Founders who improvise burn months.
This guide covers the decisions that actually matter in 2026: which legal structure to pick, how registration works, what employment really costs, and how to plan the marketing side of a French launch. One caveat up front: this is general information, not legal or tax advice. France is a jurisdiction where a good avocat and a good expert-comptable (chartered accountant) pay for themselves quickly. Hire both before you sign anything.
What starting a business in France actually involves
Strip away the mystique and a French market entry breaks into five workstreams:
Entity choice. Decide what kind of company you are creating, or whether you need a new company at all.
Registration. File the incorporation dossier through the state's single online portal, the guichet unique.
Banking. Open a business account and deposit share capital, usually the slowest step for foreign founders.
Social and tax setup. Understand what employment costs in France and how contributions are collected.
Go-to-market. Localize your acquisition strategy for a market that does not behave like the US or the UK.
The first four are procedural. The fifth is where foreign companies most often stall, because it cannot be delegated to a law firm. Let's take them in order.
Choosing your legal structure
France offers many corporate forms. In practice, foreign founders choose between three setups.
SAS and SASU: the default for foreign founders
The SAS (société par actions simplifiée) is a simplified joint-stock company, and the SASU is its single-shareholder version. It has become the default vehicle for startups and foreign subsidiaries for one main reason: the bylaws are largely freeform. You can structure governance, share classes, and investor rights with a flexibility closer to a Delaware C-corp than to traditional French forms. The minimum share capital is symbolic (one euro, legally), although banks and partners take you more seriously with real capital on the balance sheet. Shareholders' liability is limited to their contributions, the president does not need to be a French resident, and the president is affiliated with the general social security scheme as a quasi-employee rather than under the self-employed regime.
If you are a foreign company opening a French operation, or a founder planning to raise capital, the analysis almost always lands on the SAS or SASU. Confirm it with counsel anyway; edge cases exist, particularly around regulated activities.
SARL and EURL: the traditional alternative
The SARL (a limited liability company, EURL in its single-owner form) is the older, more rigid sibling. Its rules are largely fixed by the Commercial Code, which cuts drafting costs but limits how you can arrange governance and shares. It remains common for small owner-operated and family businesses. One consequential difference: a majority managing partner of a SARL falls under the self-employed social regime, which changes contribution mechanics and coverage. For venture-track companies or foreign parents, the SARL is rarely the right answer.
Branch vs subsidiary
Foreign companies can also operate in France without creating a new company:
A subsidiary is a separate French legal entity, typically an SAS, owned by the parent. It carries its own liability, contracts in its own name, and reads as a French company to customers, banks, and job candidates.
A branch (succursale) is a registered extension of the foreign parent. It can trade, but it is not a separate legal person: the parent remains fully liable for its obligations, and the branch still creates a taxable presence in France.
A liaison office sits below both, a non-commercial outpost for prospecting or representation only. The moment it starts selling, it has outgrown its status.
The pattern we see with companies entering France: those testing the market start light, and those committing to it incorporate a subsidiary. French enterprise buyers, in particular, prefer contracting with a French entity.
Registration: how the guichet unique works
Since 2023, all business formalities in France run through a single online portal, the guichet unique, which replaced the old maze of competing registration centers. Whatever your structure, the path is conceptually the same:
Draft and sign the bylaws (statuts).
Appoint the officers and, where required, an auditor.
Deposit the share capital and obtain a deposit certificate from the bank or a notary.
Publish a legal notice of incorporation in an authorized journal.
File the complete dossier through the guichet unique.
Once the filing is validated, the company is entered in the trade register, receives its SIREN and SIRET identification numbers, and can obtain its Kbis extract, the document that functions as the company's official ID in every subsequent dealing, from bank accounts to office leases. Tax registrations, including VAT, flow from the same filing; if you will be invoicing across borders, get familiar with VAT in France before you set up billing.
The official reference for all of this is service-public.fr, the French government's administrative portal, which documents each step in detail and increasingly in English.
Banking: start earlier than you think
Here is the step that actually sets your timeline. To complete incorporation you must deposit the share capital into a blocked account and obtain a certificate of deposit, which means you need a French banking relationship before your company legally exists. For French founders this is routine. For foreign founders it triggers a full compliance review of shareholders and directors, and when the shareholder is a foreign holding company, expect requests for apostilled documents, certified translations, and organizational charts.
Traditional banks are thorough and slow. App-based business banks have shortened this dramatically for straightforward cases, though complex foreign ownership structures still tend to end up with a classic bank. Two practical rules: start the banking conversation before you finalize anything else, and keep your ownership structure as simple as the deal allows. A clean cap table clears compliance faster.
Social charges: the reality check
This is the number-one budgeting surprise for US and UK companies. In France, employer social contributions are collected by URSSAF and represent a substantial layer on top of gross salary — enough that you should never budget headcount on gross figures alone. Plan on the total cost of employment, not the salary line.
What softens the picture: those contributions buy real coverage. Healthcare, pensions, and unemployment insurance are largely socialized, so the private benefits stack a US employer funds separately, health plans and retirement matching above all, is thinner or already included here. French compensation conversations revolve around net salary and total package, and the mental model transfers poorly across the Atlantic in both directions.
Your own coverage as a founder depends on the entity: an SAS president sits in the general scheme as a quasi-employee, while a majority SARL manager falls under the self-employed regime. Model this difference with your accountant before choosing a structure, not after.
Hiring: what to know before your first offer
French employment law is protective and procedural. The essentials:
The CDI (permanent contract) is the default. Fixed-term contracts (CDD) are lawful only in defined situations and convert badly when misused.
A collective bargaining agreement almost certainly applies. Conventions collectives are sector-level agreements that set minimums above statutory law: pay grids, notice periods, benefits. Identify yours before drafting an offer.
The statutory framework is real. The 35-hour reference week, five weeks of paid vacation, and mandatory employer-funded complementary health coverage are the baseline, not perks.
Termination follows procedure. Dismissal requires cause and a formal process; skipping steps creates liability regardless of the merits. Trial periods exist and are your genuine flexibility window.
None of this makes hiring in France a bad deal. The talent pool is deep, the engineering culture is excellent, and salaries are moderate against US benchmarks. It does mean that improvising employment matters is the most expensive mistake available to a foreign founder. For the broader operational picture, from contracts to business culture, start with doing business in France.
The marketing side of starting a business in France
Incorporation gets you legal existence. It does not get you customers, and this is where foreign playbooks fail quietly. France is a large, single-language market with its own search behavior, its own media economics, and a strong preference for buying in French. Four things to internalize before you spend:
French-language everything. Not translated, localized. French buyers click French results, read French reviews, and expect French support. An English-first site with a machine-translated French layer reads as exactly what it is.
Keyword behavior is not translated English. The queries French customers actually type rarely match a keyword list run through a translator. Real query research in French is the foundation of both organic and paid acquisition, and SEO in France plays by its own rules.
Consent and measurement are stricter. France's data-protection authority, the CNIL, has one of Europe's most active enforcement cultures around cookies and tracking. Build compliant consent and analytics from day one, or your acquisition data will be unusable and your exposure real.
Paid channels work, priced locally. Google and Meta dominate here as elsewhere, but auction prices, the ad formats that perform, and messaging conventions are market-specific. The full picture is in advertising in France.
This is the part of a French launch that behaves like a strategy rather than a checklist, and it rewards local expertise the same way legal setup does. When we launched Yellowpop, a direct-to-consumer neon-sign brand, on the French market, that launch was one piece of an engagement that activated three new advertising platforms and saw revenue grow 1,274% between 2019 and 2020. The lesson generalizes: treat France as a first-class market with its own acquisition system, not as a translated copy of your home market.
Frequently asked questions
How long does starting a business in France take?
The filing itself is quick once the dossier is complete; preparation and banking set the real timeline. A well-prepared incorporation with a simple ownership structure can close in a few weeks. Add foreign shareholders, apostilles, and compliance reviews, and a few months is the realistic planning horizon. Starting the banking process early is the single best way to compress it.
Do I need to live in France to open a French company?
No. You can generally be the president or shareholder of an SAS without residing in France. Living and working in France as a non-EU national is a separate question that runs through visas and residence permits, including schemes designed for founders and tech talent. Take immigration advice alongside corporate advice; they are different specialties.
Should I open a branch or a subsidiary?
If you are testing demand, a branch or liaison office keeps the footprint light. If you are committing to the market, a subsidiary (usually an SAS) limits the parent's liability and gives you a French entity that customers, banks, and candidates treat as local. Most companies that intend to sell seriously in France end up incorporating.
Can I run a French company in English?
Internally, yes; plenty of French startups operate in English. Officially, no: filings are in French, and consumer-facing materials generally must be available in French under French language law. Your market will also simply respond better in French. Plan for bilingual operations from the start.
