What Is a NIF?
The NIF (Número de Identificação Fiscal), also referred to as the Portuguese tax identification number, is a unique 9-digit number that identifies individuals and companies for tax purposes in Portugal. If you are planning to do anything official in the country — from purchasing property to opening a bank account — you will need a NIF.
For Portuguese citizens, the NIF is typically assigned at birth and appears on their Citizen Card (Cartão de Cidadão). For foreigners, the NIF must be specifically requested from the Portuguese Tax Authority (Autoridade Tributária e Aduaneira).
NIF Format
A Portuguese NIF is always 9 digits. For individuals, it typically starts with 1, 2, or 3. For foreigners without Portuguese residency, the number often starts with 5.
Why Do You Need a NIF?
A NIF is required for virtually every official and financial interaction in Portugal. Below are the most common situations where you will need your tax number.
Real Estate
- Buying or selling property
- Signing rental contracts
- Paying property taxes (IMI)
- Setting up utility contracts (electricity, water, gas)
Banking & Finance
- Opening a bank account
- Obtaining a Portuguese credit card
- Managing investment accounts
- Purchasing insurance policies

Who Can Obtain a NIF?
Anyone can obtain a Portuguese NIF, regardless of nationality or residency status. The process and requirements differ slightly depending on your citizenship and whether you reside in Portugal.
Eligibility Categories
- EU/EEA citizens — can apply directly without a fiscal representative
- Non-EU citizens with Portuguese residency — can apply directly
- Non-EU citizens without Portuguese residency — must appoint a fiscal representative
- Companies — both Portuguese and foreign-registered companies can obtain a NIF
Fiscal Representative Requirement
If you are a non-EU citizen without Portuguese residency, you are required to appoint a fiscal representative (representante fiscal) before you can obtain a NIF. This is a Portuguese resident — either an individual or a company — who serves as your official point of contact with the Portuguese Tax Authority.
2022 Rule Change for EU Citizens
Since 2022, EU and EEA citizens are no longer required to appoint a fiscal representative to obtain a NIF in Portugal, even if they do not reside in the country. Non-EU citizens without Portuguese residency still need one.
Responsibilities of a Fiscal Representative
- Receiving official correspondence from the Tax Authority on your behalf
- Forwarding tax notifications and communications to you
- Serving as the primary contact point for tax-related matters
The fiscal representative is NOT responsible for paying your taxes — that obligation remains entirely with you as the taxpayer.
Required Documents
The documents you need to bring depend on your citizenship and residency status. The table below outlines the requirements for each category of applicant.
| Applicant Type | Required Documents |
|---|---|
| EU/EEA Citizens | Valid passport or national ID card; Proof of address (home country or Portugal) |
| Non-EU with Portuguese Residency | Valid passport; Portuguese residence permit; Proof of Portuguese address |
| Non-EU without Residency | Valid passport; Proof of address (home country); Fiscal representative authorization; Representative's ID and NIF |
How to Apply for a NIF
There are three main ways to obtain a NIF. The fastest method is visiting a tax office in person, but remote options are available for those who cannot travel to Portugal.
In Person at a Tax Office (Finanças)
The fastest method — you will typically receive your NIF immediately on the same day. Visit your nearest Finanças office, take a queue number, present your documents when called, and receive your NIF card on the spot.
Through an Authorized Representative
If you cannot travel to Portugal, you can authorize someone to apply on your behalf. This requires a power of attorney (procuração) that specifically authorizes the representative to request a NIF from the Tax Authority.
Through a Professional Service
Many law firms, accountants, and specialized agencies can obtain a NIF on your behalf. This is particularly useful if you also need a fiscal representative and do not know anyone in Portugal.
Costs
The official NIF registration itself is free of charge. Costs arise only if you use professional services or require a fiscal representative.
| Item | Cost |
|---|---|
| NIF registration (official fee) | Free |
| Fiscal representative (annual fee) | €50–200/year (varies by provider) |
| Professional NIF service (one-time) | €100–300 |
Processing Time
Processing times depend on the application method chosen. In-person applications are by far the fastest.
| Application Method | Estimated Time |
|---|---|
| In person at Finanças | Immediate (same day) |
| Through an authorized representative | 1–5 business days |
| Through a professional service | 3–10 business days |
