How to set up a Sociedad Limitada (SL) in Spain — legal steps, documents, and requirements

Fast answer

A Sociedad Limitada (SL) is Spain’s standard limited liability company structure for small and medium businesses. Shareholders’ liability is generally limited to the capital contributed, and the company is governed mainly by Spain’s Capital Companies Law (Ley de Sociedades de Capital).

For UK / US / non-EU founders, the SL set-up typically requires: a name certificate, articles of association, evidence of share capital (or the applicable incorporation route), a notarial deed of incorporation, tax registration (NIF) with the Spanish Tax Agency (AEAT), and registration at the Commercial Registry (Registro Mercantil).

Quick answers

• Is an SL the same as a UK Ltd / US LLC? Similar in “limited liability” concept, but it is a Spanish legal entity with Spanish incorporation steps and registries.
• Do I need to be a Spanish resident to incorporate? Not necessarily. Non-residents can incorporate, but documentation and representation must be structured correctly.
• How long does it take? Timelines vary by notary/registry workload; most delays come from incomplete documentation or registry objections.
• Which authorities are involved? Notary + Registro Mercantil + AEAT.

What is a Sociedad Limitada (SL)?

A Sociedad Limitada (SL) is a Spanish company form designed for businesses that want a formal corporate structure with limited liability, flexible internal governance, and a recognised vehicle for contracting, banking, hiring, and operating in Spain.

In practice, it is the closest Spanish equivalent to the “limited company” concept used in other jurisdictions, but it must be constituted under Spanish law and registered in Spain.

When an SL is the right structure (and when it isn’t)

An SL is commonly used when you want:

• limited liability for shareholders
• a recognised structure for contracts, banking, suppliers, and hiring
• a scalable company vehicle for operating in Spain

It may be the wrong fit if your activity requires a different regulated structure or if your plan is purely temporary and a simpler legal route is available.

Step-by-step: how to incorporate an SL in Spain

1) Name certificate (Certificación negativa de denominación social)
Request the company name certificate to confirm the proposed name is available.

2) Articles of Association (Estatutos sociales)
Define shareholding, governance, director powers, registered address, and corporate purpose.

3) Share capital evidence
Provide the bank certificate or the legally applicable incorporation route, depending on how the SL is constituted.

4) Notarial deed of incorporation (Escritura pública)
The incorporation deed is signed before a Spanish notary.

5) Tax registration (NIF) with the Spanish Tax Agency (AEAT)
The company obtains its tax identification number and becomes operational for tax purposes.

6) Commercial Registry registration (Registro Mercantil)
Registration gives the company full public legal effect and enables many operational actions (banking, contracting, formal representation).

Key documents you should expect (high level)

Depending on the founders’ position and how the company is constituted, an SL incorporation typically involves:

• name certificate
• articles of association
• identification documents for shareholders/directors
• evidence supporting share capital / incorporation route
• notarial deed of incorporation
• tax registration steps with AEAT
• Commercial Registry filing and registration

UK / US / non-EU founders: common issues that cause delays

• Wrong legal concept imported from UK/US templates (articles must match Spanish requirements)
• Director / shareholder documentation not aligned with Spanish formalities
• Banking friction for newly incorporated entities (documentation and signatory controls)
• Registry objections due to corporate purpose wording or incomplete deed content
• Missing coordination with tax position if the founders are non-resident or the business has cross-border activity

After incorporation: ongoing legal obligations (high level)

An SL usually requires:

• corporate bookkeeping and company records
• approving and filing annual accounts where applicable
• maintaining shareholder and director resolutions when required
• tax compliance according to the company’s activity
• correct separation of personal and corporate finances (banking + accounting discipline)
