Who uses the Portuguese taxpayer number?

Anyone residing in Portugal should get a NIF number, including citizens, residents, and foreign non-residents. Whilst it’s not mandatory by law to get a NIF, you do need it if you’re engaging in official or legal fiscal activities such as renting or buying property in Portugal or signing up for utilities. 


This means that most people with financial ties to Portugal use a NIF. Anybody who has signed a legal lease, signed up for WiFi, paid taxes, or legally worked in Portugal has used their número de identificação fiscal.  

Where can I use my Portuguese NIF number?

The short answer is that you can use it in every business transaction. 


The Portuguese NIF number is used when:


  • Buying and selling property
  • Inheriting Portuguese assets 
  • Opening a bank account
  • Acquiring loans, including a mortgage
  • Paying taxes in Portugal (and for getting a tax return)
  • Receiving an income
  • Enrolling in a Portuguese university
  • Receiving social security payments
  • Setting up utilities 
  • Buying a car or applying for a Portuguese driving license
  • Signing a local contract (e.g., a mobile phone contract)

How To Get a NIF Number in Portugal

The process for getting a NIF number depends on your unique circumstances, such as whether you’re a Portuguese resident or non-resident, an EEA/EU member, or want to get your NIF in person or remotely. 


You can apply for a NIF by:


Getting your NIF as a Portuguese resident

This can be as simple as going to your local Finanças and requesting a NIF. If you’re in a large city like Lisbon or Porto, make sure you arrive at the tax office early, as there can be long waiting times for appointments.


Ensure you have all the necessary documents (we’ll get into that shortly). You can apply for a NIF through the Finanças website if you’re a business. Note that the website is only available in Portuguese, and individuals cannot apply for a NIF through the website.


Alternatively, you can contact a lawyer or accountant who can apply for a NIF number on your behalf. 

Getting your NIF remotely

You do not need to be physically present in Portugal to get a NIF. As a non-resident, you can apply from outside Portugal via a fiscal representative such as a lawyer (more on that later). 

Conveniently, we provide this service for existing or incoming clients. For more information, contact us today.

Getting your NIF as a non-EU/EEA national

If you’re applying for a NIF number as a non-European Union/European Economic Area/Swiss national, there are some additional steps to the process. Every non-EU/EEA nation is required by law to appoint a fiscal representative who can endorse their NIF application, whilst EU citizens can apply independently. 

What is a fiscal representative? 

Every non-European Union/European Economic Area citizen with economic involvement in Portugal must appoint a registered NIF tax representative with the tax department. A fiscal representative is an individual or business that functions as a point of contact between a third-country national or business and Finanças. 


The tax representative does not need to be a lawyer or accountant and can be any local Portuguese resident so long as they possess a Portuguese address. That being said, we advise against registering your NIF through a friend or acquaintance. Many local residents do not have a thorough understanding of Portuguese tax law, and it could end up in a sticky situation, especially if your friend ever leaves Portugal.

We would recommend appointing an expert such as getnifportugal.

Our Step-By-Step Guide

Step 1: Gather the required documents

First things first, you need to have the proper paperwork. Otherwise, you risk being turned away at the tax office. You’ll be asked for:


  • Official photo ID (a passport is your safest bet)
  • Proof of address in Portugal or your resident country (a utility bill or rental contract should suffice)


If you’re applying through an attorney or fiscal representative, you’ll need to submit a power of attorney translated into Portuguese, proving that they have the authority to act on your behalf. EU Citizens do not need to appoint a fiscal representative.

Step 2: Visit your nearest Finanças

If you’re applying in person, find your local tax office. Be sure to check their opening and closing hours ahead of time. 

Step 3: Get your NIF number 

After submitting the required documents, your NIF number is usually generated within a few minutes. The Portuguese tax authorities will provide you with a document stating your NIF number. Note that this number does not expire. 


How is the Portuguese tax card different from a NIF Number?

The Portuguese tax card is a credit-card-sized document with your NIF number, issue date, and the issuing regional tax authority’s name. A tax card is not compulsory, but you can request one when your NIF is issued.
