What is a Portuguese NIF Number?

A NIF, or Número de Identificação Fiscal, is a Portuguese tax ID number. It’s nine figures long and everybody in Portugal has one. It’s a unique number that links an individual with the Portuguese Tax Authorities and is even printed on the ID cards.

By having a NIF, people are registered with the Portuguese Tax offices database. It also serves to notify the authorities if the individual leaves the country, which avoids future taxation problems.

The tax identification number, abbreviated as NIF, is intended for processing tax and customs information for basically every financial transaction in Portugal.

The request for a Tax ID Number is a service that allows for the registration of a citizen or resident in national territory. The individual is added to the Tax Administration database and allows them to be identified for tax purposes.

Why is a NIF important?

The NIF is mandatory not only for individuals but also for legal entities. Therefore, everyone who has rights and duties related to tax activities needs this document. This includes children as it is required to register with schools.

Having a NIF is necessary for many activities. For example, it’s needed to open a bank account, purchase real estate, agree a lease, work and receive income, access universal healthcare and obtain a residence permit in Portugal.

How to obtain a NIF in Portugal

A NIF can be obtained by either visiting the tax authorities in person or online by accessing the e-balcão website. The process is different for non-residents and residents. 


For non-residents: For those not physically present in Portugal, they can get a temporary NIF by appointing a Portuguese Lawyer and granting them Power of Attorney. This can later be replaced with a permanent NIF when the applicant is in Portugal.


For residents: If the applicant is already in the country, they can visit the local tax office, which is called “Finanças”, or “Loja do cidadão” and is essentially a citizen advice bureau. Businesses can obtain a NIF online, however, the website is in Portuguese.

The team of Immigration lawyers at Lexidy LegalTech Boutique can help you by collecting the proper documentation on your behalf, reviewing the submission papers, tracking the progress of the application and even acting as a translator. Lexidy can be the bridge between the applicant and the immigration officials to intercept issues before they emerge.

Those already in Portugal only need a valid Identity Card and proof of their address. If the applicant is a non-EU Resident, they also must appoint a tax representative. The tax representative must have a Portuguese registered address.
