Book an appointment and choose the option for a new tax number or for registration and tax-address changes.
Prepare identity evidence, the correct declaration and supporting documents for the requested change or NIF (tax identification number) assignment. If booking without a NIF, choose the no-NIF option and enter your name. For a notice from AEAT (Spanish tax agency), have its CSV reference ready. An online NIF request for eligible people without DNI/NIE is a separate supported route. For the separate online request without DNI/NIE, the person submitting must already have a registered NIF and authenticate with an accepted electronic method; do not assume a new applicant without credentials can submit alone. Prepare the signed Modelo 030 PDF and the case-specific supporting documents. AEAT assigns a tax NIF, not the Interior Ministry’s NIE (foreigner identification number).
