Standard company formation (typically a Sociedad Limitada, SL) follows eight broadly sequential steps: (1) obtain an NIE for every shareholder/director, (2) reserve a company name via a negative-name certificate from the Registro Mercantil Central (up to 5 proposed names, issued within ~48 hours, valid 3 months), (3) open a bank account and deposit share capital, obtaining a Certificado de Ingreso, (4) sign the notarial deed of incorporation (articles of association), (5) obtain a provisional NIF, (6) register the deed at the provincial Registro Mercantil (up to 15 working days to qualify and inscribe; 7-15 days typical for a clean filing), (7) obtain the final NIF and file Modelo 036 (tax registration), and (8) register with Social Security. A clean case runs 4-8 weeks end to end and costs €600-1,500 all-in (notary, registry, gestor, filings). For a stripped-down SL with standard bylaws, the CIRCE-PAE online system bundles steps 2-8 into a single Documento Único Electrónico (DUE) process, cutting the timeline to 5-10 working days.
8-step process: NIE → name reservation → bank/capital deposit → notarial deed → provisional NIF → Registro Mercantil → final NIF + Modelo 036 → Social Security registration.

Steps
1. Obtain NIEs — Every shareholder and director needs a Spanish NIE before formation can proceed.
2. Reserve the company name — Submit up to 5 proposed names to the Registro Mercantil Central for a negative-name certificate (certificado negativo de denominación social), issued in ~48 hours and valid 3 months.
3. Deposit share capital — Open a Spanish bank account and deposit the share capital; the bank issues a Certificado de Ingreso required by the notary.
4. Sign the notarial deed — Execute the escritura de constitución (articles of association) before a Spanish notary.
5. Obtain provisional NIF — Apply for the company's provisional tax ID.
6. Register at the Registro Mercantil — File the deed with the provincial Mercantile Registry; qualification and inscription take up to 15 working days.
7. Obtain final NIF and file Modelo 036 — Convert the provisional NIF to final and complete tax registration via Modelo 036.
8. Register with Social Security — Register the company and any employees/directors with the Tesorería General de la Seguridad Social.
