Converting an SARL Into an SAS: Benefits, Considerations & Key Steps for Your Business

Many companies start out as an SARL – Société à responsabilité limitée (a French limited liability company), which is often a sound choice: the framework is straightforward, secure, and well regulated.

However, as the business grows, this structure can become too restrictive. Bringing in new shareholders, opening up the capital to investors, or preparing for a transfer of ownership – all of these developments create new needs, and the original legal structure may no longer be the best fit.

This is typically when the question of converting an SARL into an SAS arises. The SAS – Société par actions simplifiées (a simplified joint-stock company) has become the preferred corporate form for growth-oriented businesses, largely due to its flexibility in governance and organization – something the SARL cannot offer.

What is important to understand is that this conversion does not create a new company. It simply modifies the existing legal framework, while preserving the principle of limited liability for the shareholders.

Converting an SARL into an SAS allows a business to gain flexibility, bring in investors, and anticipate future growth – without creating a new legal entity.

Why consider converting an SARL into an SAS?

A conversion to an SAS is typically considered when the SARL structure begins to hinder the company’s development. While it is well suited to the early stages of a business, it quickly shows its limitations as the company enters a growth phase.

1. A natural evolution as the business grows

The SARL is an excellent legal structure for launching a business. Its operation is largely governed by statutory rules, which provides reassurance to shareholders and reduces the risk of unexpected issues.

However, as the company expands, this same framework can become restrictive. Businesses may encounter inflexible governance rules, strict requirements for transferring shares, and practical difficulties in admitting investors under favorable conditions.

The SAS addresses these challenges by allowing shareholders to tailor the company’s organization to their economic and capital objectives.

2. The key advantages of converting to an SAS

The SAS offers more flexible legal tools for structuring governance, shareholding, and growth strategies.

2.1. Tailored governance through contractual freedom

Shareholders are free to organize how the company operates. This is arguably the SAS’s greatest strength. Whereas the SARL is largely governed by mandatory provisions of the Commercial Code, the SAS allows shareholders to define their own rules in the articles of association.

In practical terms, they can:

• determine how decisions are made;
• freely structure management and supervisory bodies;
• allocate voting rights among shareholders as they see fit;
• introduce specific governance rules.

Converting to an SAS is often an opportunity to rethink the company’s internal organization: who makes decisions, under what procedures, and with what safeguards for minority and majority shareholders. Certain aspects may also be governed through a shareholders’ agreement, in addition to the articles of association.

2.2. Greater control over shareholder entry and exit

The SAS structure makes it possible to anticipate and secure changes in shareholding.

It provides particularly effective legal mechanisms to manage the entry and exit of shareholders.

The articles of association may include various provisions, such as:

• approval clauses (restricting share transfers to third parties);
• pre-emption rights;
• tag-along rights (co-sale provisions);
• exclusion clauses;
• temporary lock-up provisions restricting the transfer of shares.

This flexibility becomes especially valuable when the company’s ownership structure is expected to evolve, when shareholders wish to anticipate potential deadlock situations, or when a business transfer is being considered in the medium term.

2.3. A more suitable legal framework for attracting investors

When a company plans to open its capital to investors, the SAS generally provides a more appropriate legal framework than the SARL. In particular, it allows for the issuance of different classes of shares, as well as securities granting access to share capital.

By adopting the SAS structure, the company benefits from legal tools that are better suited to structuring the relationship between founders and investors.

2.4. More favorable tax treatment on share transfers

From a tax perspective, the transfer of shares in an SAS is significantly more advantageous than the transfer of interests in an SARL.

• Transfer of SARL interests: registration duties of 3% of the transfer price (after a proportional allowance).
• Transfer of SAS shares: registration duties of 0.1% of the transfer price, provided the company is not predominantly a real estate holding entity.

As a result, transferring a business can be considerably less costly when it is structured as an SAS.

2.5. Unchanged limited liability for shareholders

On this point, the conversion has no impact. Both the SARL and the SAS are limited liability companies: shareholders remain liable for the company’s debts only up to the amount of their contributions.

Converting into an SAS therefore does not increase the financial risk borne by shareholders.

3. Legal effects of converting an SARL into an SAS

The company remains the same legal entity, but its governance and operating framework are fundamentally transformed.

3.1. What does not change after the conversion

Converting an SARL into an SAS does not result in the creation of a new legal entity. The company remains legally the same – only its corporate form changes.

In practical terms, this means that:

• the company registration number (SIREN) remains unchanged;
• the company’s assets are preserved;
• existing contracts continue in full force and effect.

The company’s assets, receivables, liabilities, and commercial agreements (leases, supplier contracts, licenses, etc.) all remain unaffected. The conversion does not extinguish any prior debts or obligations, and creditors retain their rights against the company.

However, caution is required: certain contractual provisions may impose notification obligations in the event of a change in corporate form, or even allow for termination. It is therefore important to review existing agreements before proceeding.

3.2. What changes after the conversion

a. A complete redrafting of the articles of association

The conversion requires the adoption of entirely new articles of association, fully aligned with the legal framework governing SAS companies. This is far more than a formality: the contractual flexibility of the SAS demands careful and well-considered drafting.

In particular, the new articles must address the allocation of powers, decision-making rules, and the framework governing share transfers.

This is why converting into an SAS should be viewed as a genuine structuring legal project—not merely an administrative update.

b. From partnership interests to shares

The SARL’s equity interests (parts sociales) are converted into shares, and the logic governing their transfer also changes.

In an SARL, transfers to third parties are generally subject to a mandatory approval process.

In an SAS, by contrast, share transfers are freely transferable unless otherwise provided in the articles of association. Shareholders may nevertheless choose to include approval mechanisms if they wish to retain control over the admission of new shareholders.

c. A different management structure

In an SAS, the company must be headed by a President, who may be either an individual or a legal entity. The articles of association may also provide for additional governance bodies, such as a Managing Director, a strategic committee, or a supervisory board.

4. Key steps in converting an SARL into an SAS

The conversion process is legally regulated and involves several essential steps:

1. Appointment of a conversion auditor, responsible for preparing a report on the company’s situation.

2. Communication of the report to shareholders prior to the meeting convened to decide on the conversion.

3. Approval of the conversion at an extraordinary general meeting, typically requiring unanimous shareholder consent.

4. Complete revision of the articles of association to adopt the SAS framework.

5. Publication of a legal notice announcing the change.

6. Filing of the application with the registry to record the change in the Trade and Companies Register.

Conclusion: converting an SARL into an SAS is a strategic decision to support business growth

In practice, converting an SARL into an SAS goes far beyond a simple change of legal form on the company’s registration extract. Behind this process, there is often a broader objective: regaining control over governance, structuring shareholding, enabling fundraising, or preparing for a future transfer.

The key is to determine the right timing and the terms that best align with your specific situation.
