... about NIF

The NIF (Número de Identificação Fiscal) is your taxpayer identification number in Portugal. It’s essential for many everyday tasks, like signing a rental contract, opening a bank account, getting a mobile phone plan, or signing up for health insurance. You may also hear it called the "Número de Contribuinte".

Yes, you can request your NIF from anywhere in the world.

Usually, the process of obtaining your NIF takes between 3 to 5 business days. This duration is subject to variation based on certain factors, primarily hinging on the operational efficiency of the Portuguese Tax Office.

We support all nationalities for our NIF service.

You just need 2 documents to request your NIF:

  • A valid identification document
    • For EU Citizens: National ID Card or Passport
    • For Non-EU Citizens: Passport
  • Proof of address.

Additional requirements apply for minors.

If you are applying for a NIF for a minor under the age of 18, you need to submit the following additional requirements:

  • Birth certificate, Adoption certificate, or Legal guardianship order.
  • Copy of one parent's (or legal guardian) passport.
  • Proof of Address in the name of a parent or legal guardian.

A proof of address is a document used to verify a person's residential address for their NIF application. You can submit one of the following documents, provided it meets the conditions below:

    Language of the document: If the document is not written in the Roman alphabet, you need to provide an English translation.

    Minor: If you are requesting a NIF for a minor (child under 18), please include the proof of address of one of the parents.

If you are a citizen of the European Union (EU), the European Economic Area (EEA), or Switzerland you can register your NIF with a Portuguese address by providing a CRUE (Certificate of Registration of an EU Citizen - Certificado de Registo de Cidadão da União Europeia).

This certificate proves that you are legally residing in Portugal as an EU citizen and allows your NIF to be officially linked to a Portuguese address. Registering your NIF with a Portuguese address is important if you want to be recognized as a tax resident in Portugal.

Only EU citizens are eligible to use the CRUE for this purpose.

A CRUE (Certificate of Registration of an EU Citizen - Certificado de Registo de Cidadão da União Europeia) is an official document that confirms your legal residence in Portugal. It is required to register your NIF with a Portuguese address and to be recognized as a tax resident in Portugal.

You can obtain a CRUE at the local city hall (Câmara Municipal) in the municipality where you live in Portugal. Some municipalities may require an appointment, so it’s recommended to check their website or contact them directly before visiting.

If you are a citizen of a country outside the European Union, the European Economic Area (EEA), or Switzerland, you cannot use a CRUE. Instead, you must provide one of the following documents issued by AIMA (Agência para a Integração, Migrações e Asilo):

  • A valid residence permit, or
  • Proof of appointment with AIMA, or
  • A receipt or official document confirming that your residence permit application is pending

These documents serve to prove your legal connection to Portugal and allow your NIF to be linked to a Portuguese address. Providing the correct documentation is essential for your NIF to reflect Portuguese tax residency, which may be important for financial, legal, and tax purposes.

You can find your NIF in the upper left corner of the PDF document provided by Finanças.
