Key figures — Spain, 2025

Every figure is drawn from this Guide and cited to its source.

Recommended default entity

S.L. (Sociedad Limitada) with €3,000 capital for most commercial purposes.

Note on €1 capital

Since the Ley Crea y Crece (Ley 18/2022, 28 September 2022), the legal minimum capital for an S.L. is €1. However, if capital is below €3,000, special rules apply: 20% of profits must be allocated to legal reserves until reserves reach €3,000, and directors are jointly liable with the company for debts if the company is wound up with insufficient assets.Ley 18/2022 (Crea y Crece), 28 September 2022

Reserve company name

Apply to Registro Mercantil Central (rmc.es). Up to 5 name proposals. Cost: ~€16--€22; processing: 1--3 working days. Valid for 6 months (renewable for 3 more)

Open bank account and deposit capital

Open account in the name of "sociedad en constitución". Deposit share capital (min. €1; recommended €3,000). Obtain certificado de ingreso (bank certificate) for notary

Draft estatutos sociales

Include: company name, registered office, objects, capital, share distribution, governance structure. Can use standard or custom estatutos

Sign escritura de constitución before notary

All founders must appear (or be represented by poder notarial). Bring: NIE/DNI, bank certificate, name certificate, estatutos. Notary fee: €150--€600 depending on capital and complexity

Obtain CIF provisional

Apply at Agencia Tributaria (AEAT) with Modelo 036. Provisional CIF issued immediately; definitive CIF after Registro Mercantil registration

File with Registro Mercantil Provincial

Submit escritura to the provincial mercantile registry. Cost: €100--€400 depending on capital and region. Processing: 5--15 working days. Company legally exists upon registration

Register for taxes and social security

Modelo 036: register for Impuesto sobre Sociedades and IVA with AEAT. Autónomo societario: the administrador must register with Seguridad Social (~€370/month in 2026). Register as employer with Tesorería General de la Seguridad Social (if hiring)

Documents typically required

Escritura de constitución inscrita en Registro Mercantil (or provisional for opening). CIF / NIF. NIE or DNI of all founders and directors. Proof of address. Business activity description

Typical timeline for bank account opening

1--5 days (digital banks). 1--3 weeks (traditional banks)

R-ES-F1 -- Capital of €1 without understanding consequences

While €1 is the legal minimum since 2022, capitals below €3,000 trigger mandatory profit-reserve rules and potential joint director liability. Always advise on these constraints before proceeding.

R-ES-F2 -- Forgetting autónomo societario obligation

The administrador of an S.L. must register as autónomo societario and pay social security contributions (~€370/month in 2026). This is a significant ongoing cost that founders frequently overlook.

R-ES-F3 -- Not depositing annual accounts

Failure to deposit cuentas anuales with the Registro Mercantil results in the company being unable to file new deeds (cierre registral) and potential fines up to €60,000.

R-ES-F4 -- NIE not obtained before notary appointment

All founders and directors must have a valid NIE before the notary can execute the escritura. This is the most common cause of delay for foreign founders.

R-ES-F5 -- Shell company request

This skill will not assist in forming a company without genuine economic substance. Spanish anti-money-laundering regulations require identification of beneficial owners and real business activity.
