SL vs SA: differences and which to choose

The Sociedad Limitada (SL) and the Sociedad Anónima (SA) are Spain’s two major corporate forms. Both give shareholders limited liability, but they are designed for very different realities.

The fundamental difference: capital

The SL can be formed with €1 of capital (Crea y Crece law). The SA requires a minimum of €60,000, at least 25% paid up on incorporation. That single figure already tells you who each one is for.

Transfer of shares: participaciones vs acciones

In the SL, participaciones are not freely transferable: the articles typically give fellow shareholders a pre-emption right, protecting the shareholder base. In the SA, shares (acciones) are freely transferable as a rule, making it easy for investors to enter and exit. That is why the SA is the standard form for listed companies and those seeking external capital.

Governance and formalities

The SA has a more rigid, formal structure: general meetings with regulated notices, a board with more requirements and, above certain sizes, mandatory auditing. The SL is more flexible and cheaper to run — designed for SMEs and family businesses.

So which should you choose?

• SL: SMEs, early-stage startups, family businesses, professionals incorporating. It is Spain’s default option and the right one in 95% of cases.
• SA: projects needing large amounts of capital, multiple incoming investors, or planning an IPO. Many SAs started as SLs and converted as they grew.

Converting from SL to SA (and vice versa) is possible later, so the initial choice is not irreversible. Start with the form that fits your actual size — not the size you dream of in ten years.
