1. The NIE identification number
All individuals liable to pay taxes in Spain or having any dealing with the Spanish Tax Authorities are assigned a tax identification number.
The NIE is the Spanish tax identification number assigned to non-residents in Spain, which is required for most formal registration and administrative procedures carried out in Spain.
It enables you to pay the annual taxes or register your property, as this number identifies foreigners in Spain for tax purposes. You must indicate this number if you either buy a car or a property in Spain or open a bank account.
The NIE is applied for before the Spanish police where you will be required to submit the following documents:
- Your original passport plus 1 copy
- The NIE application form duly filled in and signed
- Bank receipt of the NIE fee payment
It is advisable to obtain legal help to apply for your NIE number before the Spanish administrative authorities (see our online service below).
2. The CIF identification number
The corporate tax identification number (CIF) is the equivalent to the VAT number. It is always required for running a business in Spain, this becomes your company’s identification for tax purposes and is required for any legal transactions.
The CIF may be issued upon application before the Spanish Provincial Tax Office (Delegación de Hacienda).
