A NIF (Número de Identificação Fiscal) is Portugal’s tax identification number, and you need one for almost everything — opening a bank account, signing a job or rental contract, or setting up utilities. EU citizens can request a NIF for free at any Finanças tax office with ID and proof of address. Non-EU citizens and non-residents usually need a fiscal representative, and can apply before arriving in Portugal, either through a lawyer or a paid online service. Getting a NIF in person is often same-day; online or remote applications typically take a few days to a couple of weeks.
Moving to Portugal to work or live? Getting a NIF is one of the first things you will need to sort out. This guide explains what a NIF is, who needs one, how to get it — in person, online, or before you even arrive — what documents and costs are involved, and how it connects to working legally in Portugal.
What is a NIF and why do you need one in Portugal?
A NIF — Número de Identificação Fiscal, also called número de contribuinte — is Portugal’s tax identification number. It is a unique nine-digit number that identifies you to the Portuguese tax authority (Autoridade Tributária e Aduaneira).
If you are moving to Portugal, the NIF is one of the very first things you will need. It is not only for paying taxes — it is required for almost every essential step of settling in:
- Opening a Portuguese bank account
- Signing an employment contract — employers need your NIF to register you
- Renting or buying property
- Setting up utilities — electricity, water, internet and mobile contracts
- Accessing healthcare and public services
- Buying a car or taking out insurance
In practice, almost nothing administrative in Portugal works without a NIF. That is why most people applying for jobs in Portugal are advised to get their NIF as early as possible — ideally before or as soon as they arrive.
Who needs a NIF?
Anyone who plans to live, work, study or carry out financial activity in Portugal needs a NIF. This includes:
- EU/EEA/Swiss citizens moving to Portugal
- Non-EU citizens relocating for work, study or residence
- Non-residents who need to carry out a transaction in Portugal — such as buying property or opening a bank account — even if they do not live there
The process differs depending on your situation. The key distinction is between residents and non-residents, and between EU and non-EU citizens — non-EU and non-resident applicants usually need a fiscal representative, explained further below.
Since Brexit, UK citizens are treated as non-EU nationals for this purpose. They follow the same process as other non-EU applicants and usually need a fiscal representative until they become tax residents in Portugal.
How to get a NIF in Portugal — step by step
There are three main ways to get a NIF. The right one depends on whether you are already in Portugal and on your nationality.
| Method | Best for | Cost | Time |
|---|---|---|---|
| In person at a Finanças office | EU citizens already in Portugal | Free | Often same day |
| Online service or lawyer | Non-residents who cannot visit an office | ~€50–150 service fee | A few days to 2 weeks |
| Through a fiscal representative | Non-EU and non-resident applicants | Lawyer/accountant fees vary | Usually a few days |
Option 1 — In person at a Finanças office
If you are already in Portugal, the most direct route is to visit a Finanças (tax office) or a Loja do Cidadão (Citizen’s Shop). Bring your identification and proof of address. EU citizens can usually do this themselves; the NIF is typically issued on the same day, free of charge.
It is worth arriving early, as tax offices can be busy. Some locations accept appointments booked in advance, which can save waiting time.
Option 2 — Online
It is increasingly possible to apply for a NIF online, without visiting an office in person. Portuguese residents with a Chave Móvel Digital (digital mobile key) can request a NIF through the Portal das Finanças.
For most foreigners, however, “online” in practice means using a paid service or a lawyer that submits the application on your behalf. These services handle the paperwork and the fiscal representative requirement, and deliver the NIF remotely — useful if you cannot visit an office yourself.
Option 3 — Through a representative
If you are not yet in Portugal, or you are a non-EU/non-resident applicant, you can apply through a fiscal representative — typically a lawyer, an accountant, or a specialised service. The representative submits the request and acts as your point of contact with the tax authority. This is the standard route for people getting their NIF before relocating.
How to get a NIF as a non-resident (before you move to Portugal)
You do not have to be in Portugal to get a NIF. Many people obtain theirs before relocating, so that everything is ready when they arrive — a bank account, a rental contract, or a job offer.
As a non-resident, you have two main options:
- Through a lawyer or accountant in Portugal — they act as your fiscal representative and submit the application for you.
- Through a specialised online service — several companies obtain NIFs remotely for a fee, handling both the paperwork and the fiscal representative requirement.
Getting your NIF before arriving is especially useful if you are relocating for a job, as your employer will need it to register your contract. Once you become a resident in Portugal, you can update your tax status and, in most cases, you will no longer need a fiscal representative.
Getting a NIF to buy or rent property in Portugal
A NIF is mandatory for any property transaction in Portugal. You cannot sign a promissory contract (contrato de promessa de compra e venda), complete a purchase deed, or sign a long-term rental contract without one.
This is one of the most common reasons non-residents apply for a NIF before ever moving to Portugal. If you are buying a home or an investment property, you can obtain your NIF in advance through a lawyer or an online service acting as your fiscal representative.
Each buyer needs their own NIF. If a couple is buying jointly, both partners need individual numbers. The same applies to renting — landlords and agencies will ask for your NIF before drawing up a lease.
Documents you need to get a NIF
The exact requirements depend on your nationality and whether you are a resident, but in general you will need:
- A valid passport or national ID card
- Proof of address — this can be your address abroad (a recent utility bill or bank statement) or a Portuguese address if you already have one
- For non-EU and non-resident applicants: the details of a fiscal representative based in Portugal
Documents in another language may need to be translated. If you apply through a lawyer or an online service, they will tell you exactly what is required and in what format.
How long does it take to get a NIF?
It depends on the method:
- In person at a Finanças office: often same day, if you have all your documents
- Through a lawyer or representative: usually a few days
- Through an online service: typically a few days to two weeks, depending on the provider
Timelines can vary, especially during busy periods. If you need the NIF for a specific deadline — such as starting a job — apply well in advance.
How much does a NIF cost?
Getting a NIF directly at a Finanças office is free — there is no government fee for issuing the number itself.
Costs arise only if you use help:
- An online NIF service — most charge a flat fee of roughly €50 to €150, covering the application and the fiscal representative
- A lawyer or accountant acting as fiscal representative — fees vary and are often higher than online services, but can be worth it if you also need wider legal or tax support
In short: the NIF itself costs nothing. What you pay for is the convenience and the fiscal representative, if your situation requires one.
Do you need a NIF representative?
A fiscal representative is a person or entity based in Portugal who represents you before the tax authority.
- EU/EEA/Swiss citizens: generally do not need a fiscal representative.
- Non-EU citizens and non-residents: usually do need one, at least until they become tax residents in Portugal.
Once you become a resident, this requirement can usually be removed. Rules in this area change, so it is worth confirming your specific situation before applying.
To remove a fiscal representative, you update your address and tax residency status with the Portuguese tax authority once you are legally resident — either at a Finanças office or through the Portal das Finanças. After that, you handle your own communications with the tax authority directly.
How to check or recover your NIF
If you already have a NIF but cannot find it, there are several ways to recover it:
- Check any official Portuguese document — your tax card, bank correspondence, or a payslip
- Log in to the Portal das Finanças if you have access credentials
- Visit a Finanças office in person with your ID
Your NIF never changes — it stays with you for life, even if you leave and return to Portugal.
Common problems and practical tips
A few things that catch people out when applying for a NIF:
- Proof of address. This is the most common sticking point. Make sure your document is recent and clearly shows your name and address.
- Busy tax offices. In-person visits can involve long waits, especially in Lisbon and Porto. Go early or book an appointment if possible.
- Fiscal representative confusion. If you are non-EU, sort out the representative before you apply — it is the step that most often causes delays.
- Online service quality varies. If you use a paid service, check reviews first. Prices and turnaround times differ significantly between providers.
- Keep your NIF safe. Save it digitally and keep a copy — you will be asked for it constantly, from supermarket receipts to contracts.
NIF and working in Portugal
If you are moving to Portugal for work, the NIF is only part of the picture. To be employed legally, you will also need a NISS (Número de Identificação de Segurança Social) — your social security number. Employers need both your NIF and NISS to register your contract and pay your social security contributions.
The typical sequence for someone relocating for a job is: get your NIF, open a bank account, secure your NISS, and then your employer can formally register you.
