Introduction

The NIE is the first thing you need to do anything legally significant in Spain. Without it, you cannot buy a property, open a bank account, sign a contract, or pay taxes. It stands for Número de Identificación de Extranjero, which translates as Foreigner Identification Number, and it applies to every non-Spanish national regardless of nationality or residency status. The good news is that once you have it, it is yours for life and never needs renewing.

Key Takeaway

• You cannot buy property in Spain without a NIE number

• The NIE costs €12 and is valid for life

• You can apply in Spain or from abroad at a Spanish consulate

• Your lawyer can apply on your behalf with a power of attorney

• Appointment waiting times vary widely, book as early as possible

• Only Spanish language forms are accepted at the appointment

What is a NIE number?

The NIE is a unique identification number assigned to all foreign nationals with economic, professional, or social interests in Spain. It consists of a letter, seven digits, and a final verification letter.

• Required for buying property, opening a bank account, and paying taxes

• Applies to both EU and non-EU citizens

• It is a tax identification number, not a residency permit

• It is not tied to residency, even as a non-resident you need it for most significant transactions

Who needs a NIE number?

Anyone who plans to buy property, work, study, or carry out any significant financial or legal activity in Spain.

• Property buyers, investors, and second home owners

• People opening a Spanish bank account

• Anyone signing a rental or employment contract

• Spanish tax authorities cannot process annual tax payments, including income tax and wealth tax, without a NIE

• Both EU and non-EU citizens, including UK buyers post-Brexit

What are the two types of NIE?

There is a non-resident NIE and a resident NIE. Most property buyers in Marbella need the non-resident version.

• Non-resident NIE: for people who are not living in Spain full-time

• Resident NIE: for people living in Spain long-term with a residence permit

• Non-EU citizens who obtain a residency visa are assigned a NIE automatically as part of that process

• For property purchases, the non-resident NIE is sufficient

What documents do you need?

Before attending your NIE appointment, make sure you have the following:

• Form EX-15 completed in Spanish, two copies (English versions are for reference only)

• Original passport and a photocopy of the biographical data page

• Form 790 Code 012 completed and stamped as paid at a bank before the appointment

• Proof of why you need the NIE, such as a property purchase agreement, mortgage contract, or official letter

• Some provinces require passport-size photos, check local requirements before attending

The EX-15 form must state a specific reason for needing the NIE. Vague reasons get rejected. Property purchase, opening a bank account, or signing a contract are all accepted reasons.

How much does it cost?

The NIE tax fee in 2026 is €12. This is paid in advance at a bank using Form 790 before your appointment. You cannot pay at the appointment itself.

• Fee: €12

• Payment method: bank payment using Form 790 Code 012 before attending

• Some banks allow payment at an ATM without needing an account

Step by step: how to apply in Spain

Step 1 - Book an appointment (cita previa)
You must book your NIE appointment on the official Spanish government website, choose your province, fill in your personal information, and confirm your appointment. In busy areas, waiting times can be 4 to 8 weeks.

Step 2 - Complete Form EX-15
Download the form, complete it in Spanish with your personal details and the reason you need the NIE. Print two copies.

Step 3 - Pay the fee
Complete Form 790 Code 012 and pay €12 at any Spanish bank before your appointment. Bring the stamped receipt.

Step 4 - Gather your documents
Bring your original passport, photocopies, both copies of EX-15, the stamped 790 receipt, and your proof of reason.

Step 5 - Attend the appointment
Submit all documents in person at the designated police station or Foreigners' Office. The NIE is typically issued within 1 to 3 weeks.

How to apply from abroad

If you are not in Spain, you can apply through the Spanish consulate in your country of residence.

• Contact the Spanish consulate covering your area and book an appointment

• If applying through a Spanish consulate abroad, the process may take 6 to 10 weeks depending on your country

• The same documents are required as applying in Spain

• Some consulates are significantly slower than others, start early

Can someone apply on your behalf?

Yes. A lawyer or gestor can apply on behalf of the applicant with a notarised power of attorney. This is the most common route for property buyers who are not yet in Spain.

• Your Spanish property lawyer can handle the full application

• You sign a power of attorney authorising them to act on your behalf

• This is particularly useful when you are buying remotely

• Most Helios Homes clients who are not based in Spain use this route

How long does it take?

A NIE is usually issued within about two weeks, but processing times can differ depending on location and demand.

• Applying in Spain: 1 to 3 weeks from appointment

• Applying through a consulate abroad: 6 to 10 weeks

• Appointment waiting times in busy provinces can add 4 to 8 weeks on top of processing

Start the process as early as possible. If you are planning to buy property in Marbella, apply for the NIE before you begin serious viewings, not after you have found the property.

Most common mistakes

These are the errors that delay most people going through the process for the first time.

• Submitting the English version of the EX-15 form instead of the Spanish version

• Forgetting to pay the €12 fee at a bank before the appointment

• Not bringing enough photocopies (bring multiple copies of everything)

• Providing a vague reason on the form without supporting documentation

• Bringing a phone screenshot of the appointment confirmation instead of a printed copy

• Applying too late, after finding a property rather than before

NIE vs NIF vs TIE: what is the difference?

These three terms cause a lot of confusion. Here is a simple explanation:

• NIE: your personal tax identification number as a foreigner, required for property purchases and most legal transactions

• NIF: the equivalent of a NIE but for businesses and companies buying property in Spain

• TIE: the physical identity card issued to non-EU residents, the NIE number is printed on it

If you are buying as an individual, the NIE is the only number you need.

Conclusion

The NIE is a simple process once you know what to expect, but it causes unnecessary delays for buyers who leave it too late or arrive at their appointment without the right documents. Apply early, use a lawyer to handle it if you are not in Spain, and make sure your form is in Spanish with a clear reason stated. Everything else in the buying process flows from having this number in place.
