Número de Identificación de Extranjero
A NIE number is a unique identification number for non-residents in Spain. You need this number to pay taxes and carry out official transactions, such as buying a home. When you buy a house in Spain, you are obliged to pay non-resident tax annually. Without a NIE number, you cannot pay the purchase taxes either. Are you buying together with your partner or someone else? Then you both need your own NIE number.
Fortunately, there are several ways to apply for a NIE number.
