What is the difference between SASU and EURL?

✅ In brief

SASU and EURL both allow you to create a company alone, but they do not operate in the same way.

🧭 What you need to know

• The SASU is a single-shareholder form of SAS, led by a président.
• The EURL is a single-shareholder form of SARL, led by a gérant.
• Social security, tax and operating rules may differ.
• There is no automatic most suitable choice.

🛠️ How Leegal supports you

• Leegal helps you understand the wording shown during the creation process and prepare a clearer file.
• The flow can organize information, documents and points to watch, but it does not replace a personalized review.
• If your situation is specific, it is still preferable to ask a chartered accountant, a lawyer or another qualified professional for advice.

🔎 Points to check

• Your planned remuneration.
• Your need for flexibility in the statuts.
• Your plan to welcome future associés or shareholders.
• Advice from a chartered accountant if you are unsure.

⚖️ Limits to know

• Leegal is not a law firm or an accounting firm.
• Leegal explains the options and helps prepare formalities, but does not choose for you.
• Tax, social security or personal asset consequences can depend on your actual situation.

📌 Key takeaway

SASU and EURL are both serious options for creating alone, but the right choice depends on the project and the company officer.
