How to Register a SASU or EURL in France: Steps, Costs and Timeline

How to register a company in France (SASU or EURL): step by step

Updated 6 November 2026 · 6 steps

To register a SASU or EURL in France, set the capital, purpose and registered office, write and sign the articles, deposit the capital, publish a legal notice, then file everything on the Guichet Unique run by INPI. The registry issues your Kbis with your SIREN number, usually within a few days to two weeks. Official fees come to about €225; total cost is roughly €225 to €465 if you use an online platform for the articles.

A French one-person company takes about two to four weeks if you wait for each step, and about ten days if you prepare the documents in parallel. Here is the order for a SASU or an EURL, with the official fees. Figures checked on 06/11/2026; confirm them with an expert-comptable before you commit.

1. Set the basics

Decide the share capital (any amount from €1), the business purpose and the registered office. These go into the articles, and changing them later means a new filing.

2. Write and sign the articles

The articles of association (statuts) set out how the company works. You can write them yourself, use an online platform (up to about €200) or pay a lawyer (usually €800 to €2,000).

3. Deposit the capital

Pay at least half of the cash capital into a bank, a notary or the Caisse des Dépôts. You get a deposit certificate, usually within one to three days. The money stays blocked until the company is registered.

4. Publish a legal notice

Announce the company’s creation in an authorised legal-notice newspaper (journal d’annonces légales) for your department. The price is fixed: €170.40 including VAT in mainland France.

5. File on the Guichet Unique

Everything is filed online on the Guichet Unique run by INPI: the signed articles, the capital and legal-notice certificates, the president’s or manager’s ID, proof of the registered office and the beneficial-owner declaration.

6. Receive your Kbis

The registry checks the file and issues the Kbis extract with your SIREN number, usually within a few days and sometimes up to two weeks at busy times. That is your proof the company exists.

Typical costs

Item	Cost
Legal notice (mainland France)	€170.40
Registration with the trade and companies register	€33.83
Beneficial-owner declaration	€19.33
Articles via an online platform	€0 to about €240

Official fees come to about €225. A lawyer for the articles usually brings the total above €1,200.

Questions, answered

The official fees are about €225 including VAT - the legal notice, the registration with the trade and companies register and the beneficial-owner declaration. Using an online platform for the articles brings the total to roughly €225 to €465; a lawyer usually costs €1,200 or more.

Both are one-person companies that protect your personal assets. In a SASU the president is treated like an employee for social security, which costs more but gives fuller cover; in an EURL the manager is self-employed, which costs less. Dividends and pay are taxed differently too, so ask an accountant to model your numbers.

For many solo founders, yes. A micro-entreprise registers for free on the same Guichet Unique and is open while turnover stays at or below €83,600 for services or €203,100 for goods (2026 to 2028). Switch to a SASU or EURL when you need liability protection, partners or more room to grow.

Yes. The whole process is online, but the company needs a registered office address in France, and you will need a French business bank account or one that accepts French company deposits.
