Spanish company NIF and CIF: tax identification explained
CIF remains common in informal speech, but the current tax identifier for a Spanish legal entity is its NIF. Legal name, number and tax address should be used consistently.
Short answer
Spanish company NIF and the old term CIF
The NIF identifies the entity for tax purposes. A provisional number may be assigned during incorporation and made definitive after the required documents are completed. “CIF” is historical terminology, not an additional tax identifier.
NIF is the current term
The old term CIF does not create a second number and does not replace the company’s legal name.
Provisional and definitive stages
The incorporation phase and documents supplied determine when identification is completed.
Details must match
Invoices, contracts, banks, the tax census and the Commercial Registry should avoid inconsistent variants.
