How to Get Your NIF in Portugal

What is a NIF?

The NIF (Numero de Identificacao Fiscal), also known as the tax number or fiscal number, is a 9-digit identification number issued by the Portuguese Tax Authority (Autoridade Tributaria e Aduaneira). Every person — Portuguese citizen or foreign national — who has financial obligations in Portugal needs a NIF.

Think of it as your essential gateway document. Without a NIF, you cannot open a bank account, sign a rental lease, register for healthcare, or even buy a SIM card in Portugal.

Who Needs a NIF?

Everyone who plans to live, work, study, or conduct any financial activity in Portugal needs a NIF. This includes:

• Immigrants applying for residency permits
• Workers (employed or self-employed)
• Students enrolled in Portuguese universities
• Property buyers or renters
• Anyone opening a Portuguese bank account

Documents Required

The documents you need depend on whether you are an EU/EEA citizen or a non-EU citizen.

For EU/EEA Citizens

• Valid passport or national ID card
• Proof of address in Portugal (rental contract, utility bill, or a declaration from your host)

For Non-EU Citizens

• Valid passport
• Proof of address in Portugal
• A fiscal representative (representante fiscal) — required if you don't yet have a Portuguese address

How to Apply: Step by Step

Option 1: In Person at a Financas Office

1. Find your local Financas office — Search on the Portal das Financas website for the nearest Servico de Financas.
2. Go during opening hours — Most offices are open Monday to Friday, 9:00 AM to 3:30 PM. Arrive early as wait times can be long.
3. Take a ticket — Use the ticketing machine and select the option for NIF attribution.
4. Present your documents — Show your passport, proof of address, and fiscal representative documents (if applicable).
5. Receive your NIF — You will receive a paper document with your NIF printed on it, usually the same day.

Option 2: Online via Portal das Financas

EU citizens with a valid Citizen Card can apply for a NIF online through the Portal das Financas. Non-EU citizens generally need to apply in person for the initial NIF issuance.

Option 3: Through a Loja do Cidadao

Some Loja do Cidadao (Citizen Shops) have a Financas desk where you can apply for a NIF. These multi-service centres may have shorter wait times than standalone Financas offices.

After Getting Your NIF

Once you have your NIF, you should:

1. Register on Portal das Financas — Create an online account to access tax services, submit declarations, and download your NIF card.
2. Open a bank account — Your NIF is required. See our guide to opening a bank account.
3. Get your NISS — If you plan to work, you will need a NISS (Social Security number).
4. Apply for residency — Start your residence permit application if you haven't already.
5. Use your NIF for invoices — Always provide your NIF when making purchases. Portugal's e-fatura system gives tax deductions for registered invoices. Learn more in our tax guide.

Common Mistakes to Avoid

• Not bringing proof of address — Many people arrive at Finanças without a Portuguese address document. If you don't have one yet, arrange a fiscal representative before going.
• Going to the wrong office — Make sure you go to a Serviço de Finanças (tax office), not a Segurança Social office or Loja do Cidadão without a Finanças desk.
• Not registering on Portal das Finanças afterwards — Your NIF paper document is just the first step. Register online to access tax services, download your digital NIF card, and manage e-Fatura. If you move house later, remember to update your NIF address.
• Forgetting to use your NIF on purchases — Every invoice with your NIF can reduce your annual tax bill through the e-Fatura system. Start using it from day one.
• Confusing NIF with NISS — The NIF is your tax number (from Finanças). The NISS is your social security number (from Segurança Social). You need both, but they are obtained separately. You may be able to request both at the same time — see the combined service above.

Common Questions

Can I get a NIF before arriving in Portugal?

Yes, through a fiscal representative. Some services allow you to obtain a NIF remotely, but you will still need someone in Portugal to act as your fiscal representative.

How long does it take?

If you apply in person with all required documents, you typically receive your NIF the same day — often within 30 minutes of your appointment.

Is there a fee?

No, obtaining a NIF is free. However, you may need to pay a fiscal representative if required (typically 50-150 euros per year).
