How to Get a Portuguese Fiscal Number (NIF): Step-by-Step

Published on 2nd January, 2026

What is a NIF and Why Do You Need One in Portugal?

The NIF is your personal tax identification number in Portugal, assigned by the Autoridade Tributária e Aduaneira (Portuguese Tax and Customs Authority). You will find that it is required for nearly every official or significant financial activity in the country. These include, but are not limited to:

Opening a Portuguese bank account.
Buying or renting property.
Signing employment contracts or setting up as a freelancer.
Registering for and paying taxes.
Setting up utility contracts (water, electricity, internet).
Purchasing a car.
Inheriting assets in Portugal.
Accessing the public healthcare system (in some circumstances).

Essentially, without a NIF, navigating daily life and any formal procedures in Portugal becomes exceedingly difficult. It is a foundational requirement for integrating into the Portuguese system.

Who Can Apply for a NIF?

Anyone, regardless of their nationality or residency status, can apply for and obtain a Portuguese NIF. This includes:

Portuguese citizens.
EU/EEA (European Union/European Economic Area) citizens.
Non-EU/EEA citizens.
Residents of Portugal.
Non-residents of Portugal who have financial interests or activities in the country (e.g., owning property, investments).

Step-by-Step Guide to Obtaining Your NIF (as of 2025)

While the process is generally straightforward, requirements can sometimes be updated. It's always advisable to check the latest information on the official Portal das Finanças or consult with a legal professional. Here’s a general outline:

Step 1: Gather Required Documents
- For EU/EEA Citizens:
  - Valid Passport or National Identity Card.
  - Proof of address from your home country (if applying as a non-resident) or your Portuguese address (if applying as a resident). This could be a recent utility bill or a bank statement.
- For Non-EU/EEA Citizens:
  - Valid Passport (with visa if applicable).
  - Proof of address from your home country. If you do not have a Portuguese address and are applying as a non-resident from outside the EU/EEA, you will typically need to appoint a fiscal representative (see Step 2).
Step 2: Appoint a Fiscal Representative (If Required)
- A fiscal representative (representante fiscal) is mandatory for non-EU/EEA citizens who are applying for a NIF as non-residents and do not have a permanent address in Portugal. This representative must be a tax resident in Portugal (an individual or a company) and agrees to be the point of contact between you and the Portuguese Tax Authority. They are responsible for receiving tax-related correspondence on your behalf.
- EU/EEA citizens applying as non-residents generally do not need a fiscal representative if they can provide a valid EU/EEA address, but it can sometimes simplify communication.
- Many legal firms and specialised service providers in Portugal offer fiscal representation services for a fee. The team at www.PortugalProperty.com often works with clients who require such services and can point them towards trusted professionals.
Step 3: Apply at a Finanças Office (Autoridade Tributária e Aduaneira) or Online
- In Person: You (or your appointed fiscal representative) can apply for a NIF at any local Finanças office. It's advisable to check if an appointment is needed, as this can vary.
- Online: It is sometimes possible to initiate the NIF application process through the Portal das Finanças, especially if you have a fiscal representative or are an EU citizen with digital authentication means recognised by Portugal. The exact online procedures can evolve, so checking the portal for the most current options is recommended.
Step 4: Submit Documents and Pay Fee (If Any)
- Present all your gathered documents (and those of your fiscal representative, if applicable).
- Generally, there is no fee charged by the Tax Authority for the initial issuance of a NIF. However, if you use a lawyer, solicitor, or a fiscal representation service, they will charge their own professional fees.
Step 5: Receive Your NIF Document
- If applying in person and all documentation is correct, the NIF is usually issued on the spot. You will receive a document (often a simple A4 paper printout) containing your NIF number and personal details.
- If applied for through other means, it might be sent electronically or by post to your fiscal representative or your registered address.

Using Your NIF

Once you have your NIF, keep the document in a safe place. You will need to provide this number frequently for many transactions in Portugal. It’s wise to memorise it or keep a digital copy handy.

Important Notes & Tips

Check Current Requirements: Tax laws and administrative procedures can change. Always verify the latest NIF application requirements on the official Portal das Finanças (www.portaldasfinancas.gov.pt) or with a qualified professional before starting the process.
Consider Professional Assistance: Especially if you are a non-EU/EEA citizen, applying from abroad, or find the bureaucracy daunting, consider using the services of a lawyer, solicitor, or a specialised NIF service provider. They can ensure your application is correct and act as your fiscal representative if needed.
Early Application for Property Buyers: Clients of PortugalProperty.com looking to purchase property are often advised to obtain their NIF early in the process, as it is required to make offers, sign promissory contracts, and ultimately complete the purchase.
