SL vs SA: choosing the right Spanish entity for foreign investors

Two corporate vehicles, one legal system

Spain offers two primary corporate forms for doing business: the Sociedad Limitada (SL) and the Sociedad Anonima (SA). Both provide limited liability to shareholders, both are subject to the same corporate income tax rate (25%), and both are governed by the Spanish Corporate Enterprises Act (Ley de Sociedades de Capital).

The differences that matter for foreign investors are in capital requirements, governance formality, share transferability and access to capital markets.

Quick reference: key differences

Understanding participaciones vs acciones

This is the most practically significant difference:

SL participaciones: Ownership units in an SL cannot be freely sold to third parties. The law (and typically the company’s articles) grants existing shareholders a right of first refusal. Any transfer to an outsider requires either the agreement of the other shareholders or compliance with a statutory procedure. This is protective for founder control but creates friction for investors seeking liquidity.

SA acciones: Shares in an SA are freely transferable to anyone unless the articles specifically restrict this. This default transferability is what enables stock market listing and makes SA shares attractive for investors who want exit flexibility without needing the other shareholders’ consent.

For early-stage companies backed by venture capital, the SL with a comprehensive shareholder agreement is standard practice in Spain. Investors in SLs use contractual mechanisms — drag-along, tag-along, pre-emption rights, liquidation preferences — to replicate the protections they would have in an SA, but within the SL structure.

Capital requirements: a real barrier for SAs

The EUR 60,000 minimum capital of an SA is a genuine barrier for early-stage ventures. While 75% can remain uncalled for years (only EUR 15,000 must be paid at incorporation), this capital must be demonstrably available and properly documented.

By contrast, under the Ley Crea y Crece (2022), an SL can be incorporated with EUR 1 in share capital. The practical caveat: if capital is below EUR 3,000, shareholders are jointly and severally liable for any shortfall during insolvency, and profits cannot be distributed until the combined share capital and reserves reach EUR 3,000. Incorporating with EUR 3,000 avoids both complications.

Governance: flexibility vs rigour

SL governance

An SL can be managed by a single administrator (administrador unico) with minimal formality. There is no legal requirement for a formal board, audit committee or remuneration committee unless the company is large enough to trigger mandatory audit thresholds. Annual accounts must be approved by the shareholders’ meeting and filed at the Mercantile Registry within six months of year-end.

SA governance

An SA’s default structure assumes a board of directors (consejo de administracion) for companies of any significant size. General shareholder meetings (juntas generales) have mandatory notice requirements — minimum 15 days — with publication in the Official Commercial Registry Gazette (BORME) for listed companies. Listed SAs must also comply with the Good Governance Code (Codigo de Buen Gobierno), maintain an audit committee and publish annual corporate governance reports.

For an unlisted SA with a small number of shareholders, governance requirements are manageable but still more burdensome than an equivalent SL.

When does Spain require an SA?

Certain regulated sectors require SA status by law:

• Credit institutions (commercial banks, savings banks)
• Insurance companies (Ley de Ordenacion, Supervision y Solvencia de Entidades Aseguradoras)
• Investment management companies (SGIIC, SGICC, SGFT)
• Listed companies on any Spanish regulated market
• SOCIMIs (Spanish Real Estate Investment Trusts — listed REIT equivalent)
• Some public service concession holders by specific contract requirement

For all other activities, the choice is voluntary.

The path from SL to SA

Converting an SL into an SA is a well-travelled road in Spain. The process involves:

1. Shareholders’ resolution approving the transformation
2. Preparation of a transformation balance sheet (audited if required)
3. Notarial deed of transformation
4. Registration at the Mercantile Registry
5. Publication in the BORME

Total cost: EUR 2,000-5,000 in professional and registry fees, plus ensuring the company’s net worth covers the EUR 60,000 SA capital requirement at the time of conversion.

The critical lesson from practice: do not wait until you are in due diligence for a Series C round to transform. The conversion creates a legal reorganisation event that can complicate tax, employment contracts and commercial agreements. Plan it at least 12 months before the trigger event.

Recommendation for foreign investors

Operating subsidiary of a foreign group: SL. Faster, cheaper and sufficient for all operational purposes. A robust investment agreement between parent and subsidiary covers governance.

Joint venture with Spanish partners: SL with a shareholders’ agreement drafted under Spanish law. Standard market practice.

Platform acquisition target in regulated sector: Check sector-specific rules. May require SA.

Growth company planning a Spanish IPO or BME Growth listing: Incorporate as SA if the listing horizon is under 5 years. If it is 5+ years away, start as SL and convert when the timeline is confirmed.
