You’re about to set up a company in Spain and someone tells you: ‘You need to choose between an SL and an SA.’ You nod — but you have no idea what that means or which one is right for you. You’re not alone. This is one of the most common questions we get from foreign entrepreneurs and investors entering the Spanish market. The answer is simpler than it looks.
In Spain, the two main corporate structures are the Sociedad de Responsabilidad Limitada (SL) and the Sociedad Anónima (SA). Both provide limited liability protection — meaning your personal assets are protected from the company’s debts. But they differ significantly in capital requirements, governance, flexibility, and cost. Here’s how to choose.
What is an SL (Sociedad de Responsabilidad Limitada)?
An SL is Spain’s equivalent of a private limited company. It is by far the most common business structure in Spain, used by startups, SMEs, family businesses, and professional service firms. Key features:
- Minimum share capital: €3,000 (must be fully paid up at incorporation)
- Shares cannot be freely transferred without shareholder approval
- No requirement to list on a stock exchange
- Simpler governance: fewer mandatory corporate formalities
- Ideal for: small to medium businesses, family companies, startups, foreign subsidiaries
What is an SA (Sociedad Anónima)?
An SA is Spain’s equivalent of a public limited company. It is typically used by larger companies, listed entities, or businesses that need to raise capital from many investors. Key features:
- Minimum share capital: €60,000 (at least 25% must be paid up at incorporation)
- Shares can be freely transferred unless the articles restrict this
- Can be listed on the stock exchange
- More complex governance: mandatory board structures, stricter rules on shareholder meetings
- Ideal for: large companies, joint ventures with institutional investors, businesses planning a future IPO
SL vs SA: head-to-head comparison
Share capital
SL: minimum €3,000, fully paid upfront. SA: minimum €60,000, with at least €15,000 paid at incorporation. For most foreign investors starting a business in Spain, the SL’s lower capital requirement is a practical advantage.
Transfer of shares
In an SL, shares (called participaciones) cannot be freely sold or transferred — other shareholders have pre-emption rights and the transfer must be approved. In an SA, shares (acciones) are freely transferable by default, making it easier to bring in new investors or exit the company.
Corporate governance
An SL can be managed by a single administrator, two joint administrators, or a board of directors — and the rules are flexible. An SA requires a more structured board of directors with defined quorum and voting rules, and a shareholders’ meeting with stricter formality requirements.
Audit requirements
Both types of company are required to have their accounts audited if they exceed two of these three thresholds for two consecutive years: total assets above €2.85 million, net turnover above €5.7 million, or more than 50 employees. Below these thresholds, neither is mandatory.
Cost and administration
An SL is cheaper and simpler to set up and maintain. Notary and registration fees are lower, ongoing compliance is less burdensome, and there is more flexibility in the articles of association. An SA involves higher incorporation costs and more ongoing administrative requirements.
Which one do most foreign investors choose?
In practice, the overwhelming majority of foreign investors and companies setting up in Spain choose the SL. It is faster to incorporate, cheaper to run, and provides all the protections needed for most business activities. The SA is generally reserved for specific situations where the volume of shareholders, the need to raise capital publicly, or the nature of the regulated industry demands it.
Can you convert an SL to an SA later?
Yes. Spanish law allows transformation of one company type into another (transformación social) through a formal process involving notarisation, shareholder approval, and registration with the Registro Mercantil. It is possible but involves legal and administrative costs — so choosing the right structure from the start is preferable.
Frequently asked questions
Can a single foreign person own 100% of an SL or SA?
Yes. Both structures allow a single shareholder (socio único), including a non-resident foreigner. The company is then referred to as an SL Unipersonal or SA Unipersonal. This must be registered and the sole shareholder must comply with specific disclosure rules.
How long does it take to incorporate an SL in Spain?
A standard incorporation via notary and Registro Mercantil takes approximately 4 weeks. However, this timing may differ depending on how we want to structure the company and the foreign shareholders.
What is the tax treatment of an SL vs SA?
Both SL and SA are subject to Spanish corporate income tax (Impuesto sobre Sociedades) at the general rate of 25%. There is no tax difference between the two structures. The choice between SL and SA is a legal and governance decision, not a tax one — though the overall structure of ownership (including holding companies or the Beckham Law) may create tax planning opportunities.
Do I need a Spanish resident director?
No. Spain does not require the administrator or directors of an SL or SA to be Spanish residents or nationals per se. However, in practice, Public Administration requires to have at least one local director or general attorney in the company, which is registered in Social Security.
