Creating my company

A SASU is a simplified single-shareholder company, meaning it has only one shareholder.

The single-member SAS status is particularly popular, accounting for a majority and stabilising at 37% of companies created in 2018, a record!

The SASU can be used to carry out many commercial, craft and agricultural activities. It's flexible and depends on your preferences when you set it up.

Focus on the complete guide to the SASU!

The SASU is the most flexible legal form for starting a business.

Why create a SASU? 

The SASU has great flexibility: the sole shareholder can be an individual or a legal entity, and there is no minimum capital required. If the capital contributions exceed €30,000, or if their amount exceeds half of the share capital, it is essential to appoint an auditor.

The sole shareholder of the SASU is free to organize the operation of their company as they wish in its articles of association. The SASU must be managed by a President, who is most often the sole shareholder.

Why choose a SASU over an EURL?

There are several differences to consider between a SASU and an EURL.

First of all, the social security system of the manager is not the same: the sole manager of an EURL is a self-employed worker, while the president of a SASU is treated as an employee.

So, there's an impact on social security contributions and the quality of social protection.

The profits of an EURL are taxed directly in the hands of the sole member. In a SASU, they are taxed in the name of the company.

If you receive dividends, the SASU only pays social security contributions at a rate of 15%, which is much less than the tax burden in an EURL.

How much does it cost to set up a SASU?

Several costs need to be taken into account:

  • Installation preparation course, around €200 ex VAT
  • Involvement of a contribution auditor
  • The publication of a notice of incorporation for your SASU, between €100 and €200 excluding VAT.
  • The fees of the commercial court registry, amounting to €41.50

How long does it take to set up your SASU? 

Drafting the articles of association, preparing the administrative documents to be completed (M0 form, depositing the blocked capital in a bank account, etc.) and publishing an advertisement in a legal announcement journal take several months.

Once you've submitted the complete application to the commercial court registry, it usually takes around 3-4 weeks to get confirmation that your company has been created.

Which tax system should I choose?

You have the choice between taxation under income tax (IR) or corporate tax (IS). In the first case, the profits are taxed in the name of the partner at the progressive income tax rates.

Losses can be deducted from the sole partner's overall taxable income. In the second scenario, profits are taxed in the company's name at the standard corporate tax rate.

Losses can be carried forward to offset future profits. The remuneration received as Chairman is taxable as income tax in the salaries and wages category.

In both cases, social charges are calculated only on the amount of remuneration.

How are you remunerated?

The rules for the remuneration of a SASU President are defined in the articles of association when the company is created. There is no obligation to pay yourself.

If the President pays himself a salary, it's subject to income tax under the category of salaries and wages, based on the amount of compensation he receives as part of his role.

If the President receives dividends, he will be liable for income tax, in the category of income from movable capital, on the amount of his dividends as well as the interest remunerating his current account.

What is the social security system for a SASU director?

The President of SASU is treated as an employee and is affiliated with the general social security system. If they are not paid, they are not affiliated with any social security coverage.

What assistance are you entitled to when creating your SASU?

If the President is registered on the list of job seekers, he can benefit from aid to create his company.

You can benefit from ACRE and keep your benefits (ARE).

You can also opt for a lump-sum payment of half of your remaining entitlements. Support schemes for business creators exist in the form of zero-interest loans, guarantees or long-term advice.

Although the flexibility of the SASU allows for the exercise of many activities, it is important to seriously consider the most suitable legal status according to your needs.
