A foreigner who has a residence permit can become a tax representative and obtain a NIF for other people. We will tell you how to do this, as well as what problems may arise.
The first step is for the person who wants you to become their tax representative to visit a notary and make a power of attorney for you. The power of attorney should specify the action – obtaining a fiscal number in Portugal (Obtenção de NIF em Portugal).
Create a single PDF file containing the following documents: (1) Power of attorney, (2) passport of the person for whom you want to obtain a NIF, (3) proof of address in the country of residence (a utility bill or bank statement is best), and (4) certificate of fiscal number in the country of residence. If the documents are not in English, add a translation made by a certified translator.
On the Finanças portal, you need to go to the “Minha área” section, located in the top menu. Then go to “Fale conosco – Contacte-nos” and select “Atendimento e-balcão”. Click on the “Registrar nova questão” button and fill out the form, sequentially selecting the following options from the drop-down lists: Registro Contribuinte, Identificação, Atrib/Alter NIF Singulares. In the Assunto field, specify “Obtenção de NIF em Portugal”. In the Mensagem field, write a text stating that you wish to obtain a fiscal number for the person whose data you provide. Attach the file with the documents in PDF format. Click the “Registrar Questão” button. You will receive the NIF by mail.
However, remember that by becoming a tax representative, you are responsible for timely informing the person about all letters that arrive in their name from the tax service. You will be responsible for any consequences if you do not forward an important letter in time. If you decide to move to another apartment, you need to change your fiscal address and have access to the previous mailbox for some time, as some letters may arrive late at the old address.
As part of the course on Migration and Tax Laws in Portugal, you will receive clear instructions on how to change the address in the NIF. See you in the lessons at ExpatClass.com.
