How to Create a SASU in 2026
The Single-Member Simplified Joint-Stock Company (SASU) remains one of the most popular legal structures for entrepreneurs who want to start a business on their own. Its flexibility, limited liability, and potential for future growth make it an attractive option for consultants, freelancers, artisans, retailers, and startup founders. In 2026, creating a SASU involves several legal and administrative steps that every entrepreneur should understand before launching their business.
What Is a SASU?
A SASU (Société par Actions Simplifiée Unipersonnelle) is a French company structure owned by a single shareholder. It is essentially the single-shareholder version of the SAS (Simplified Joint-Stock Company). This legal form allows an entrepreneur to operate independently while benefiting from a separate legal entity and limited liability.
One of the key advantages of a SASU is its flexibility. The sole shareholder has significant freedom to determine how the company will be managed and organized through its articles of association. This makes the structure suitable for a wide range of business activities and growth strategies.
Advantages and Disadvantages of a SASU
The SASU offers several important benefits. First, it provides considerable flexibility in terms of governance and management. The sole shareholder can tailor the company’s rules to meet specific business needs.
Another major advantage is the protection of personal assets. In principle, the shareholder’s liability is limited to the amount invested in the company, helping separate personal finances from business obligations.
The president of a SASU who receives a salary benefits from a social security system similar to that of employees. This status provides access to comprehensive social protection, excluding unemployment insurance.
The SASU is also highly scalable. If the business expands and additional investors or partners join the company, it can easily be converted into a multi-shareholder SAS without significant legal complications.
However, the structure also has some drawbacks. Social contributions for a salaried president can be relatively high compared to other business forms where the manager is considered self-employed. Additionally, if the president chooses not to receive a salary, no social contributions are due, but no social protection is acquired through the business activity.
Steps to Create a SASU
Creating a SASU requires completing several mandatory procedures.
1. Draft the Articles of Association
The articles of association are the foundation of the company. They define how the business will operate, identify the powers of the president, establish decision-making procedures, and specify the characteristics of the share capital.
The document should include information such as the company’s management structure, the appointment process for the president, shareholder rights, contributions made to the company, and any other provisions governing the business.
Careful drafting is essential to ensure the company operates smoothly and remains aligned with the founder’s objectives.
2. Establish and Deposit the Share Capital
The share capital represents the resources contributed to the company upon its creation. Contributions may take several forms:
- Cash contributions, consisting of money deposited into the company.
- Contributions in kind, such as equipment, property, or other assets.
- Contributions in industry, which consist of expertise, knowledge, or professional skills.
Cash contributions must be deposited with a bank or authorized institution to obtain a certificate confirming the deposit of funds. This certificate is required for the registration process.
3. Publish a Legal Notice
A legal announcement must be published in an authorized legal publication within the department where the company’s registered office is located. This publication informs third parties of the creation of the company and provides key information about its structure.
After publication, an official certificate is issued and included in the registration file.
4. Register the Company
The final step is submitting the registration application through France’s official business registration platform. Once the application is approved, the company receives its Kbis extract, which serves as the official proof of the company’s legal existence.
Required Documents
Several documents must be prepared when creating a SASU:
- Signed articles of association.
- Certificate confirming the deposit of share capital.
- Certificate of legal notice publication.
- Declaration of non-conviction and parentage for the company president.
- Completed online registration forms.
Providing accurate and complete documentation helps avoid delays in the registration process.
How Much Does It Cost?
The cost of creating a SASU depends largely on the level of support chosen by the entrepreneur.
Those who complete the process independently generally only pay mandatory administrative fees. Others may choose to work with lawyers, accountants, or specialized legal service providers to receive professional assistance.
Additional expenses may include legal notice publication fees, share capital deposit fees, registration costs, and professional advisory services. Entrepreneurs should carefully evaluate their budget and the complexity of their project before selecting the most appropriate option.
When Is the Best Time to Create a SASU?
A SASU can be created at any time during the year. However, many entrepreneurs prefer launching their company at the beginning of a fiscal year to simplify accounting and tax management.
The timing of incorporation may also influence certain administrative and tax obligations. Planning ahead can help optimize the company’s financial and operational organization.
Financial Support and Assistance
Several support schemes may help entrepreneurs finance and launch their business.
Eligible job seekers may continue receiving unemployment benefits through the ARE program while developing their company. Another option is ARCE, which allows beneficiaries to receive part of their unemployment rights as a lump-sum payment to support their business project.
The ACRE program may also provide partial reductions in social security contributions during the first stages of activity for eligible entrepreneurs. Since eligibility conditions can change over time, it is important to verify the current requirements before applying.
Post-Creation Obligations
After the company has been registered, additional administrative obligations must be fulfilled. These include tax registrations, accounting requirements, and ongoing compliance with French business regulations.
Expenses incurred before incorporation may also be reimbursed by the company under certain conditions. This mechanism allows the SASU to assume eligible costs initially paid by the founder during the preparation phase.
Conclusion
The SASU remains one of the most attractive legal structures for solo entrepreneurs in France. It combines flexibility, limited liability, strong growth potential, and a professional corporate framework. While the creation process involves several legal and administrative steps, careful planning and proper preparation can make the process straightforward. By understanding the requirements, costs, and available support programs, entrepreneurs can build a solid foundation for their future business success.
