What Is an NIE Number in Spain? Complete Guide

Last updated: March 2026

Introduction

If you are a foreigner dealing with Spain—whether buying property, working, or investing—you will need an NIE (Número de Identificación de Extranjero).

This number is essential for almost all legal, financial, and tax-related activities in Spain. In this guide, we explain what the NIE is, how to get it, and what to do next.

While Taxadora does not assist with NIE applications, we help you manage your Spanish tax obligations once you have your NIE.

What Is an NIE Number?

The NIE is a unique identification number assigned to foreigners in Spain.

It is required for:

• Buying property in Spain

• Opening a bank account

• Paying taxes

• Signing utility contracts

• Starting a business

• Working legally

• Applying for residency or a visa

Important:

• The NIE is not a residence permit

• You can have an NIE without living in Spain

• Your NIE never changes, even if your residency status changes

Types of NIE Numbers

There is one NIE number format, but two common situations:

Non-Resident NIE

• For one-off or limited activities

• Used for property purchases, taxes, or investments

• Does not grant residency or work rights

Resident NIE

• For individuals living in Spain

• Required for employment, long-term stay, or studies

• Linked to residency documentation

Important:

Your NIE number stays the same—only your tax status and obligations change.

How to Apply for an NIE

You can apply in three ways:

In Spain

• At a Policía Nacional station or Foreigners’ Office

• Requires an appointment (often difficult to obtain)

At a Spanish Consulate

• Apply from your home country

• Usually slower but more predictable

Through a Legal Representative

• A lawyer or gestor can apply on your behalf

• Often the fastest and most convenient option

Required Documents

• Completed EX-15 form

• Valid passport and copy

• Proof of reason (e.g. property purchase, job, tax need)

• Payment form (Modelo 790)

How Long Does It Take?

• In Spain: same day or a few days (if you have an appointment)

• Consulate: several weeks

The main delay is usually getting an appointment, not processing.

Why the NIE Is Important for Taxes

Once you have an NIE, you may have tax obligations such as:

• Non-resident tax (Modelo 210)

• Rental income tax

• Capital gains tax when selling property
