Creating a SAS in Luxembourg: governance and flexibility

The Luxembourg Société par Actions Simplifiée, or SAS, is a capital company built around flexible articles of association. It can suit a joint venture, a closely held group company or an investment structure when voting rights, transfers and governance need to be arranged in detail.

The answer is not simply that the SAS is more flexible than an SA. That flexibility shifts more responsibility to the drafting stage. The articles must state who decides, how decisions are taken and what happens when shareholders enter, transfer shares or leave.

The SAS in plain terms

The SAS has legal personality and shareholders are generally liable only up to their contributions. One shareholder is sufficient, with no statutory maximum. The company must be formed by notarial deed.

The current Companies Law applies a limited set of mandatory SAS rules and imports certain SA rules where the SAS chapter is silent. This creates room for tailored governance, but the articles cannot override mandatory law.

Share capital and formation

The minimum subscribed capital is EUR 30,000. At least 25% of each cash subscription must be paid at incorporation. A SAS formed entirely with cash at the minimum therefore starts with at least EUR 7,500 paid in.

Cash and in-kind contributions are possible. An in-kind contribution requires a valuation report from an approved statutory auditor. The capital, share classes, governance bodies and signing powers are then recorded in the notarial deed and published through the RCS.

The incorporation timetable has no universal statutory duration. It depends on the readiness of the ownership and governance information, the capital-payment route, beneficial-owner checks, drafting and notary availability.

The mandatory president

Every SAS has a president who represents the company towards third parties. The president may be an individual or a legal entity. The articles define appointment, removal and term of office.

Additional bodies may be created, such as a management committee or a board. Their powers must be written clearly because the SAS does not rely on the same complete statutory board framework as the SA. Internal restrictions may organise responsibility between bodies, while third-party representation must remain consistent with the published signing rules.

Shareholder decisions

The articles determine most decision procedures, voting thresholds and consultation methods. Some matters remain reserved to shareholders by law, including capital changes, mergers, divisions, dissolution, changes of legal form, appointment of auditors, approval of annual accounts and allocation of results.

This distinction keeps the SAS flexible without removing shareholder control over structural decisions. It also makes the articles central to the operating model. A short set of generic articles may fail to address deadlock, conflicts of interest or the division of powers expected by the investors.

Share classes and transfers

The SAS may create different share classes and attach distinct economic or voting rights within the law. The articles may also include approval rights, pre-emption rights, lock-up periods and transfer mechanisms. These provisions are useful only when they describe a workable process and remain consistent with any shareholders’ agreement.

The SAS cannot carry out a public issue of shares. This statutory limit is stated in the official SAS guidance. A structure that may later seek public equity funding should compare the SAS with the SA before incorporation rather than assume that a later conversion will be neutral.

Comparison with the SA and SARL

Point	SAS	SA	SARL
Minimum capital	EUR 30,000	EUR 30,000	EUR 12,000
Minimum shareholders	1	1	1
Main management body	Mandatory president	Board or two-tier structure	One or more managers
Governance rules	Largely set by the articles	More fully prescribed by law	Simpler manager framework
Public issue of shares	Not permitted	Possible subject to applicable market rules	Not designed for public share issuance
Transfer rules	Mainly set by the articles	Generally transferable, subject to restrictions	Statutory approval framework for third-party transfers

The SAS is not automatically preferable for every investment structure. It adds value when tailored rights and decision rules are genuinely needed. A SARL may remain clearer for a closely held subsidiary with straightforward governance.

Audit and annual obligations

A SAS below the statutory audit perimeter generally has one or more commissaires aux comptes. An approved statutory auditor becomes required when two of the following three limits are exceeded for two consecutive financial years under the current Accounting Law.

Criterion	Current limit
Balance-sheet total	EUR 7,500,000
Net turnover	EUR 15,000,000
Average full-time employees	50

The company keeps accounting records, approves annual accounts and files them with the RCS within one month after approval and no later than 7 months after year end. Tax returns, beneficial-owner information and any VAT or payroll obligations follow separate calendars.

Tax treatment

The SAS is fully taxable under the ordinary Luxembourg corporate regime. Holding activity does not create a separate tax status. A SAS used to own participations may be described in the market as a SOPARFI, but participation exemption, treaty access and substance depend on their own conditions.

The same separation applies to operating authorisations. The SAS form does not authorise a regulated or commercial activity by itself. The corporate object, business permit and sector-specific approvals must match the activity actually carried on.

Conclusion

The Luxembourg SAS combines limited liability with broad freedom to organise governance and share transfers. Its main advantage is not a lighter capital requirement, since it shares the EUR 30,000 minimum with the SA. Its value lies in carefully drafted rules that fit a specific shareholder and decision structure.
