What is the NIF?
The NIF (Numero de Identificacion Fiscal) is the Spanish tax identification number. Every person and every company that is tax-relevant in Spain needs a NIF. It is the equivalent of the German tax ID and is used for all dealings with the Agencia Tributaria (Spanish tax authority / Hacienda).
For Spanish citizens the NIF is identical to the number on their DNI (Documento Nacional de Identidad). For foreigners the NIF is identical to the NIE number.
Important: NIE = NIF for foreigners
If you are a foreigner living in Spain and already have a NIE number, you automatically also have your NIF. You do not receive a separate tax number. Your NIE number (e.g. X1234567Z) is at the same time your NIF.
NIE vs. NIF - the difference
Confusing the NIE and NIF is one of the most common misunderstandings among German expats. Here is the clear distinction:
NIE (Numero de Identidad de Extranjero): Your personal identification number as a foreigner in Spain. It is issued by the Policia Nacional (Extranjeria) and serves as a general identifier for all official processes.
NIF (Numero de Identificacion Fiscal): The tax identification number. For Spanish citizens this is their DNI number, for foreigners it is their NIE number. The NIF is therefore not a separate number but a concept - the number under which you are recorded for tax purposes.
In practice this means: when a form, a bank or a landlord asks for your NIF, simply provide your NIE number.
Tip: CIF, NIF, NIE - the abbreviations
CIF was the old term for the tax number of companies (now also called NIF). NIF is the current term for the tax number of all persons and companies. NIE is specifically the foreigners identification number. As a foreigner your personal NIF is your NIE.
What do I need the NIF for?
You need your NIF (i.e. your NIE) in Spain for almost all official and commercial transactions:
Tax return (Renta/IRPF): Without a NIF you cannot file a tax return. Your entire tax profile at the Agencia Tributaria runs under this number.
Opening a bank account: Every Spanish bank requires your NIF when opening an account. Without a NIF/NIE there is no account.
Signing an employment contract: Your employer needs your NIF for payroll and tax remittance.
Buying property or renting: A NIF is required for rental contracts and purchase contracts. Without it no contract can be concluded.
Receiving and issuing invoices: Every official invoice (factura) in Spain must state the NIF of both buyer and seller.
Buying or registering a vehicle: The DGT (traffic authority) also requires your NIF for vehicle registration.
How do I get my NIF?
As an EU citizen you receive your NIF automatically when you apply for your NIE number. No additional step is required.
Step 1: apply for your NIE number. Follow our NIE number guide. Once you have your NIE, you also have your NIF.
Step 2: register with the Agencia Tributaria (optional). If you want to carry out tax-relevant activities (e.g. as a self-employed person), you need to register with the tax authority using Modelo 036 or 037. You need your Certificado Digital for this.
Step 3: provide your NIF for all transactions. Use your NIE number whenever the NIF is requested - at the bank, with your employer, on invoices and in contracts.
Tip: Certificado Digital for online access
With the Certificado Digital you can handle all tax matters online at the Agencia Tributaria - filing your tax return, downloading certificates and viewing your tax data. It is worth applying for it early.
Tips and common mistakes
Mistake: trying to apply for a separate NIF. Many Germans try to apply for an extra NIF in addition to their NIE. This is not necessary - your NIE is your NIF.
Mistake: confusing NIE and NIF
If a form says NIF and you enter your NIE number, that is correct. Do not be confused - for foreigners both numbers are identical.
Tip: check the NIF on invoices. For important invoices (rent, electricity, insurance), check that your NIF is recorded correctly. Incorrect numbers can cause problems when filing your tax return.
Tip: Modelo 036/037 for the self-employed
As an autonomo you need to register with the Agencia Tributaria using Modelo 036 or 037. This activates your NIF for business purposes. Your Gestor (tax advisor) can handle this for you.

Do I need the NIF to open a bank account?
