2025 Guide to Getting Your NIF in Portugal – by LusoLynk

What is a NIF?

The NIF is your Portuguese tax identification number-used for everything from signing rental contracts to opening a bank account. It's a 9-digit code issued by Autoridade Tributária e Aduaneira (the Portuguese Tax Authority). It's not just for taxes-think of it as your financial passport in Portugal.

Why You Need a NIF

You'll need a NIF to:

- Open a Portuguese bank account
- Sign a lease or property purchase agreement
- Get a job and pay taxes
- Connect utilities (electricity, water, internet)
- Register for healthcare
- Enroll in university
- Start a business

No NIF = No paperwork gets done.

Who Can Apply for a NIF?

Anyone can apply-whether you're an EU citizen, non-EU national, a tourist, a remote worker, or a student.
- EU/EEA/Swiss nationals can apply directly.
- Non-EU nationals will need a fiscal representative in Portugal.

At LusoLynk, we act as your trusted fiscal representative, making the process smooth and reliable.
