Spain — Forming a Company (Sociedad Limitada) as a Foreigner
The Sociedad Limitada (SL) is the standard company vehicle for foreigners setting up a business in Spain (as opposed to registering as an autónomo/sole trader, which is covered elsewhere). Spain runs a government electronic one-stop-shop, CIRCE (Centro de Información y Red de Creación de Empresas), that can incorporate an SL in as little as 24-48 hours by routing a single electronic filing to the notary, the Registro Mercantil (Companies Registry), the Agencia Tributaria (tax agency, AEAT) and Social Security simultaneously.
Choosing the right entity and using the CIRCE fast track (instead of a fully manual, paper-based incorporation) materially changes how long it takes a newcomer to legally start invoicing, hire staff, and open a business bank account in Spain — the difference between roughly two days and up to a month.
Key Facts
Minimum share capital for an SL is €1 under the "SL Sucesivos" regime created by Ley 18/2022 ("Crea y Crece"), which replaced the previous €3,000 minimum (BOE-A-2022-15818, amending the Ley de Sociedades de Capital).
If capital is set below €3,000, the company must allocate at least 20% of annual profits to a legal reserve until reserves plus capital reach €3,000, and partners are jointly liable for the shortfall (up to €3,000) if the company is wound up before reaching that threshold.
CIRCE's DUE (Documento Único Electrónico) bundles more than 25 separate administrative forms into a single filing.
Access to CIRCE is via a PAE (Punto de Atención al Emprendedor) — either an in-person network point (chambers of commerce, town halls, participating gestorías) or the self-service "PAE Virtual" portal — authenticated with Cl@ve or an electronic certificate.
Every company needs its own NIF (tax ID), separate from any individual owner's NIE/NIF, requested from AEAT via Modelo 036.
Unconfirmed: multiple private legal-sector sources state that a foreign individual acting as company administrator or shareholder must first obtain a NIE (Número de Identificación de Extranjero), and that missing this can be the main cause of delay (cited as 2-6 weeks via a Spanish consulate). I could not confirm this specific requirement against an official AEAT, Registro Mercantil, or Ministry of Justice page during this session — verify directly with the Registro Mercantil or a gestor before relying on it.
Steps
1. Reserve the company name — Request a "certificación negativa de denominación social" from the Registro Mercantil Central, listing several name options in order of preference.
2. Get a provisional NIF for the company — File Modelo 036 with AEAT along with the negative name certificate and the "acuerdo de voluntades" (pre-incorporation agreement). This must happen before any invoicing, purchasing, or hiring.
3. Deposit the share capital — Open a Spanish bank account and deposit the chosen share capital (minimum €1). Confirm current bank-deposit-certificate requirements with the notary, as practice can vary depending on the capital amount chosen — this detail was not independently confirmed via an official source this session.
4. Complete the DUE through a PAE — Provide company details, partner/shareholder data, registered address, and business activity (CNAE code), either in person or via PAE Virtual.
5. Sign the deed of incorporation before a notary — This is the only in-person step in the CIRCE process. Using standardized bylaws ("estatutos tipo") and a CIRCE-affiliated notary qualifies for the fastest processing track.
6. Registro Mercantil registers the company — The registrar must inscribe the company within six working hours of receiving complete documentation.
7. AEAT issues the definitive NIF — The definitive NIF is communicated electronically through CIRCE once the company is registered; Social Security employer registration is processed in parallel if the company will hire staff.
Costs
Minimum share capital: from €1 (many advisers recommend €3,000+ if the company needs credibility with banks, suppliers, or corporate clients).
I did not find a single official page consolidating notary and Registro Mercantil fees during this session — flagged as unconfirmed; check with a notary or notariado.org for current fee scales.:
Timelines
24-48 hours via CIRCE when using standardized bylaws and a CIRCE-network notary.:
Up to 15-30 days for a traditional, non-standardized incorporation route.:
When processed outside CIRCE, AEAT must assign a NIF within 10 business days of a complete Modelo 036 request.:

Common Mistakes
Setting capital at €1 without understanding the mandatory 20%-to-reserve rule until reserves reach €3,000.
Not using a CIRCE-network notary, which forfeits the speed advantage of the one-stop-shop process.
Invoicing or contracting before the provisional NIF is granted.
Foreign founders leaving NIE applications until the last minute, given the multi-week consular processing times reported by private-sector sources.
