Company setup

OOD (LLC) and EOOD (single-shareholder LLC) are common structures. Formation is well-documented. Corporate tax is at a flat rate; VAT registration depends on activity.

SL (Sociedad Limitada) is the standard private company. Registration involves NIE / NIF, notary, mercantile registry, and tax registration. Spanish tax residency triggers worldwide income reporting; the Beckham Law (special tax regime) may apply to eligible relocated workers.

Sp. z o.o. (limited liability) is the standard private entity. Online formation via S24 is possible; otherwise notary registration. Tax registration, VAT, and ZUS (social contributions) follow. CIT and the new estonian-style lump-sum CIT regime may apply.
