SRL or SA in Belgium: which legal form should you choose?

Key takeaways

• The SRL imposes no legal minimum capital; the SA requires €61,500 fully paid up at incorporation.
• Both forms can be incorporated by a single founder since the 2019 CAC reform.
• SA shares are freely transferable by default, which makes it easier for investors to come in.
• The SRL suits SMEs and individual projects; the SA is aimed at structures seeking outside capital.

Choosing between SRL and SA is one of the first structuring decisions a Belgian entrepreneur faces. The two forms share one essential feature: shareholder liability is limited to their contribution. But they diverge on key criteria, starting with capital: no legal minimum for the SRL, €61,500 fully paid up for the SA. Depending on the profile of the project, that single point can settle the choice for good.

SRL and SA: two different philosophies

The SRL is defined in Article 5:1 of the Companies and Associations Code (CAC) as a company without capital. The 2019 reform removed the minimum capital requirement that applied to the former SPRL. The legislator replaced that formal guarantee with a mandatory financial plan, which must demonstrate that the initial resources are sufficient for the first two financial years (Art. 5:4 §1 CAC).

The SA follows a different logic. It targets larger structures, open to the capital markets, with a minimum capital of €61,500 fully paid up at incorporation (Art. 7:4 CAC). This requirement is a real guarantee for creditors and third parties. The SA is the preferred form for companies anticipating growth through fundraising, arrangements with multiple shareholders or, in time, a stock exchange listing.

The comparison criteria at a glance

	SRL	SA
Minimum capital	None	€61,500
Paid up at incorporation	Per the financial plan	In full (€61,500)
Minimum number of founders	1	1
Financial plan	Mandatory (Art. 5:4 CAC)	Mandatory
Share transfers (by default)	Subject to approval	Free
Management body	Manager(s)	3 options (board, sole director, dual)

The summary fits in two lines: the SRL is accessible and flexible from day one; the SA imposes real capital but opens more doors for growth and external financing.

Capital and initial financing

For the SRL, the absence of minimum capital does not remove the need for rigour. Article 5:4 §1 CAC requires a forward-looking financial plan covering the first two financial years, handed to the notary before the deed of incorporation is signed. If the company is declared bankrupt within three years and the initial equity was manifestly insufficient, the founders can be held personally liable for the debts (Art. 5:16 CAC). The freedom the SRL offers therefore comes with a demand for rigour when preparing the file.

For the SA, the €61,500 must be fully subscribed and paid up from incorporation. This requirement naturally filters lightly capitalised projects towards the SRL, and reserves the SA for founders who genuinely hold or raise that initial stake.

Governance and day-to-day management

The SRL is reputed to be more flexible in management terms. Managers are appointed by the shareholders; their mandate, their powers and the decision-making rules can be freely arranged in the articles of association. There may be one or several managers, natural or legal persons.

Since the CAC reform, the SA has three governance models to choose from. The classic one-tier model: a board of directors made up of at least three directors (Art. 7:85 CAC), reduced to two if the company has fewer than three shareholders. The lighter model: a sole director (Art. 7:101 CAC), who may be the same person as the sole shareholder. The two-tier model: a separate management body and supervisory body (Art. 7:104 CAC), adopted mainly by large structures.

Share transfers and opening up the capital

This is often the decisive criterion. In the SRL, shares are registered and their transfer is subject to approval: absent any clause in the articles to the contrary, a transfer requires the written consent of at least half of the shareholders (by head) representing three quarters of the shares, excluding the shares being transferred. This restriction protects the cohesion of the shareholder base but can deter outside investors who want to come in or out quickly.

In the SA, shares are in principle freely transferable. An investor can enter or leave the capital without having to obtain the consent of the other shareholders, unless the articles of association provide otherwise. This is why the SA is systematically recommended as soon as a project anticipates several financing rounds, business angels or an eventual valuation.

Which form to choose for your profile

Choose the SRL if you are launching an activity with one or a few trusted partners, if you have no intention of raising outside funds in the short term, or if you want to start with modest contributions backed by a solid financial plan. The SRL is the default form for the vast majority of SMEs and self-employed people incorporating in Belgium: flexible, accessible, and suited to the Belgian economic fabric.

Choose the SA if your project requires structured capital from the outset, if you anticipate institutional investors or business angels coming in, or if free transferability of shares is a prerequisite of your financing strategy.

Whichever form you settle on, the registered office address must be fixed before you go to the notary: it is one of the details recorded in the articles of association and at the Crossroads Bank for Enterprises. A professional domiciliation in Brussels lets you separate private life from business activity, and settle this point well in advance.
