NIE number or becoming a resident in Spain? This is the difference
One of the first questions I get from people wanting to buy in Spain is: "Do I need a NIE number?" And almost immediately after: "Do I then also have to become a resident?"
The answer is surprisingly simple: no, they are not the same thing.
What is a NIE number?
A NIE (Número de Identidad de Extranjero) is a personal identification number for foreigners in Spain. You need it for many official matters, such as:
- buying a property;
- opening a Spanish bank account;
- applying for a mortgage;
- water and electricity contracts;
- tax matters;
- buying a car;
- taking out a phone contract.
So even if you are not a resident, you usually still need a NIE number.
What does being a resident mean?
Becoming a resident means you officially live in Spain. That brings both rights and obligations, such as taxes, health insurance and municipal registration. Whether becoming a resident is wise depends on your personal situation, so good advice matters.
When do you have to become a resident?
In many cases you become a tax resident when you spend more than 183 days per year in Spain. But other circumstances also play a role, such as where your economic and social life takes place. It's wise to discuss this in advance with a tax adviser.
Can I buy a property without being a resident?
Yes. In fact, many of my clients first buy a holiday or second home and continue to live back home. Residency is not required for that.
First a NIE, later residency
For many people the process goes roughly like this:
- You explore properties.
- Your lawyer applies for your NIE via a power of attorney.
- You buy the property.
- You first enjoy holidays or longer stays.
- Only later do you decide to move to Spain permanently and become a resident.
That's a very common order. During the purchase I guide you step by step and connect you, where needed, with reliable lawyers and gestors.
In closing
A NIE number and residency are often confused, but they are two very different things. You almost always need a NIE when buying a property. Becoming a resident is a personal choice that depends on your plans, your stay and your financial situation. In doubt? I'm happy to think along and make sure you reach the right specialist.
