SASU: advantages and drawbacks in 2026

Updated March 2026 - The SASU remains one of the favourite structures for founders who launch a business alone. It is attractive because of its flexibility, its image and the possibility of bringing in future shareholders more easily. But it is not automatically the best choice.

The main strengths usually highlighted are:

• ▸broad statutory flexibility;
• ▸a clear framework if shareholders may join later;
• ▸an attractive governance logic for certain founder profiles;
• ▸a clear separation between the individual and the company.

The main limits often concern:

• ▸the social cost of remuneration;
• ▸real administrative discipline;
• ▸and poor suitability for certain low-margin or simplicity-driven projects.

The SASU can therefore be an excellent structure, but only when its advantages match the actual economics of the business and the founder's remuneration strategy.

Hayot Expertise insight: choosing the SASU only for dividends or for image reasons is often a mistake. The right choice comes from looking at remuneration, social charges, social protection and the development horizon together.

The structure often works well for:

• ▸consultants and freelancers with comfortable margins;
• ▸projects likely to raise funds or welcome new shareholders;
• ▸founders who want a clear separation between personal wealth and business activity;
• ▸entrepreneurs looking for flexible governance.

Before deciding, it is worth looking closely at:

1. ▸the level of turnover and margin;
2. ▸the founder's remuneration strategy;
3. ▸the need for statutory flexibility;
4. ▸the probability of bringing in a shareholder later.

The wrong way to choose a SASU is to rely on slogans. The right way is to compare the real cost of the structure with other options based on your own figures, your protection needs and your growth scenario.
