What the NIF is used for

The Número de Identificação Fiscal identifies you to the Portuguese tax authority. It is used for contracts, banking and property transactions. Residents and non-residents can apply; holders of a Portuguese Citizen Card generally already have a NIF.

Preparing the application

We first check whether you already have a NIF and establish the purpose of your application and your country of residence. We review the documents and authority needed, prepare the file and follow its submission and any requests for clarification.

Documents and remote assistance

Identification and proof of address are usually required. When acting on your behalf, we check the power of attorney and the applicable formalities. The documents needed depend on your circumstances.

Tax identification, residence and representation

A NIF is not a residence permit. Authority to apply for the number is distinct from tax representation. We assess representation or electronic notification obligations according to your residence and tax connections with Portugal.

After the number is assigned

We assist with checking your details and preparing the next steps, whether for a property purchase, inheritance or other matters in Portugal. If you change residence, we can help assess which records need updating.
