If you're planning to live, work, study, or invest in Portugal, one of the first things you’ll need is a Portuguese NIF number. The NIF (Número de Identificação Fiscal) is the tax identification number issued by the Portuguese Tax Authority (Autoridade Tributária e Aduaneira) and is essential for nearly every financial or legal transaction in the country.
Whether you’re an expat settling into a new life or a foreign investor buying property in Portugal, understanding how to get a NIF in Portugal is an important early step in your journey.
What Is a Portuguese NIF Number?
The Portuguese NIF number is a unique nine-digit number assigned to each individual or legal entity for tax and financial purposes. It’s comparable to a Social Security Number in the United States or a National Insurance Number in the UK, although it is used more broadly in everyday transactions.
A NIF number is required not only for filing taxes, but also for a wide range of common activities, including:
In short, having a NIF number is fundamental to fully participating in economic and civic life in Portugal.
Who Needs a NIF Number?
Anyone residing in Portugal, even temporarily, or planning to conduct business or invest in the country will need a NIF. This includes:
For expats, the NIF number for expats Portugal is typically the first administrative step after arrival—or even before arrival, if property purchase or legal arrangements are already underway.
How to Get NIF in Portugal
The process of obtaining a Portuguese NIF number is generally straightforward, though it differs slightly depending on your residency status.
1. If You Are a Resident of Portugal: Residents can apply for a NIF directly at a local tax office (Serviço de Finanças). You’ll need to bring the following documents:
The NIF is issued on the spot and is free of charge if you are registering as a resident.
2. If You Are a Non-Resident (Including Expats and Investors): If you are not a resident, you can still apply for a NIF. However, Portuguese law requires that non-residents appoint a fiscal representative who resides in Portugal. This representative acts as your official contact with the tax authorities.
You’ll need to provide:
Many legal or relocation services in Portugal offer assistance with obtaining a NIF for non-residents, which can be especially helpful if you're trying to complete real estate transactions from abroad.
Using the NIF for Real Estate Transactions
At Portugal Investment Properties, we frequently work with international buyers who are preparing to purchase property in the Algarve, Lisbon, Porto, and other regions. One of the very first steps in this process is obtaining a Portuguese tax identification number.

We recommend that prospective buyers begin the NIF application process early in their planning, especially if they are organizing a purchase from outside Portugal.
What Happens After You Get Your NIF?
Once you receive your NIF, it becomes your permanent tax identification number in Portugal. It will be required on all official paperwork, including tax returns, contracts, and government documentation.
Your NIF will also determine your tax residency status and obligations. If you reside in Portugal for more than 183 days in a year or have a permanent home here, you may be considered a tax resident and subject to Portuguese tax laws.
Can You Get a NIF Before Moving to Portugal?
Yes, many expats and investors apply for a NIF before moving to Portugal. This is particularly common for those who want to secure a property or apply for a visa (such as the D7 or Digital Nomad Visa) in advance. With the help of a lawyer or a fiscal representative, it's possible to obtain the NIF remotely by granting power of attorney to a local representative.

The Portuguese NIF number is much more than just a tax ID—it's your access point to living, working, and investing in Portugal. From renting a home to buying a villa on the coast or enrolling in a health insurance plan, the NIF is essential.

Whether you're an expat relocating to Lisbon or someone interested in buying property in the Algarve, getting your NIF early on is a simple but crucial step.
