How to get a NIF in Portugal: a complete guide for expats and foreigners

If you’re planning to live, work, or invest in Portugal, one of the first things you’ll need is a NIF (Número de Identificação Fiscal), Portugal’s tax identification number. Whether you’re buying property, opening a bank account, or signing up for utilities, the NIF is essential. In this guide, we’ll explain what a NIF is, why it’s important, and how to obtain one as a foreigner in 2026.

What is a NIF in Portugal?

A NIF, also called a tax identification number, is a unique nine-digit number issued by the Portuguese Tax Authorities (Autoridade Tributária e Aduaneira). It is used to identify individuals and businesses for tax purposes. Every resident, non-resident, or foreigner conducting financial or legal transactions in Portugal needs a NIF.

Key uses of a NIF

• Opening a Portuguese bank account
• Signing rental or property purchase agreements
• Registering for utilities (electricity, water, internet)
• Paying taxes or social security contributions
• Buying a car or registering a business

Without a NIF, many basic services and legal transactions in Portugal are impossible.

Who can apply for a NIF?

Both residents and non-residents can obtain a NIF. If you’re a foreigner, you’ll typically need a representative in Portugal, such as a legal guardian or accountant, to act on your behalf. EU citizens may have slightly simpler procedures compared to non-EU citizens.

How to get a NIF in Portugal

There are several ways to obtain a NIF, depending on whether you are in Portugal or applying from abroad.

Applying in person in Portugal

1. Visit a local Tax Office (Serviço de Finanças): Bring your passport or EU ID card.
2. Provide a Portuguese address: Even a temporary one will suffice.
3. Designate a fiscal representative (required for non-residents).
4. Receive your NIF instantly: The number is issued on the same day.

Getting a NIF through a representative

If you’re not in Portugal, you can appoint a fiscal representative. This could be a lawyer, accountant, or specialised service. You’ll need to provide:

• A certified copy of your passport
• Proof of your representative’s appointment

The representative submits the application on your behalf and can send your NIF to you remotely.

Online application (limited options)

Some services allow foreigners to request a NIF online via legal representatives. This option is growing but usually requires verification of identity documents and can take a few days.

Costs and fees

Obtaining a NIF in Portugal is free at the tax office. If you use a fiscal representative or online service, fees typically range from €50 to €150, depending on the provider.

Tips for expats and foreigners

• Keep your NIF safe: You’ll use it frequently for financial and legal matters.
• Update your address: If you move within Portugal, inform the tax authorities to avoid fines.
• Use it for all official transactions: Even small purchases like mobile phone contracts or SIM cards may require a NIF.
