Frequently Asked Questions about NIF

Is there any fee for issuing the NIF besides the service fee?

No. The tax authority does not charge any fee for issuing the NIF.

Will I receive a physical document?

The proof of the tax identification number that you will receive is an electronic document.

When is a representative necessary?

When the applicant does not have residence in Portugal, as a rule, it is necessary to have a representative who is a tax resident in Portugal.

Does representation include VAT purposes?

No. Representation for VAT purposes can be contracted separately and requires an independent process.

By having a NIF as a non-resident, do I have any tax obligations in Portugal or need to pay taxes?

Simply having a NIF as a non-resident does not create any declarative or tax payment obligations.

Can I replace my tax representative?

Yes, it is possible to replace your tax representative by submitting a request to the Tax Authority.

If I need a tax representative but no longer have one, what happens?

The Tax Authority will grant a deadline for you to present a representative, under penalty of your NIF becoming inactive.

Does having a NIF grant me the right to live in Portugal?

A NIF may be one of the required documents for a residency visa request. There is no direct relation between having a NIF and being legally allowed to live in Portugal.

What do I need the NIF for?

You will need the NIF to submit certain visa applications; to conduct certain commercial transactions and contracts in Portugal; to open a bank account; to register as self-employed in Portugal; among other situations.

Why must I be careful when choosing my representative?

The representative will act as the bridge between you and the Tax Authority. You must be certain that he/she is able to receive any and all communications on your behalf and inform you in a timely manner. You cannot use failure of communication with your representative as a justification before the Tax Authority in case you fail to comply with some obligation for which you were notified.

I am a foreigner living in Portugal but I do not have a residence permit/card. How do I apply for a NIF?

As a rule, you will have to apply for the NIF as a non-resident and, once you have the residence permit/card, update your address.

I am Portuguese, live in Portugal, but I don’t have a rental contract or proof of address. How do I apply for the NIF?

As a rule, you should apply for the NIF as a non-resident and, once you have proof of address, update your address.

Can a minor/child have a NIF?

Yes, the NIF may be assigned both to children/minors and adults. In the case of a child/minor, the power of attorney will mention the applicant’s details together with the details of the legal representatives. In this case, the power of attorney will be signed by the legal representatives.

Dra. Vivian Perfeito is incredible. My husband and I got stuck in our immigration process with no idea what to do next. We scheduled a consultation with Dra. Perfeito and she was extremely helpful. At a time when my husband and I were feeling hopeless, she lifted us up and provided the perfect path and plan for us to continue our dreams here in Portugal. We could write one-million words to describe how helpful, caring and smart Dra. Perfeito is. Though we are so overjoyed we find ourselves almost speechless. We will absolutely be continuing to get assistance with our immigration process from Dra. Perfeito. We recommend her so so so SO highly. If you have any doubts about booking a consultation with her, throw the doubts away and BOOK THE CONSULTATION. Dra. Vivian Perfeito is a life saver and our guardian angel on earth. If we could rate her TEN-THOUSAND STARS, we would. We are eternally grateful to have found her.

I can not recommend Vivian enough! I hired her when I was in London, preparing to apply for the Digital Nomad Visa, and she was phenomenal!

Her advice was clear, she was understanding, and was always quick to communicate. There was an instance where I flew into Porto to attend to some matters, and within a day, with Vivian's help, I had obtained my tax number and a bank account.

As someone who could barely make sense of the entire process, I can only say that Vivian was the perfect person to hire, and I highly recommend her for anyone else in a similar position.

She assisted me in preparing all the necessary documentation for my residence permit renewal and also helped with the legal defence submission to AIMA, all within a single appointment. During our in-person meeting, I found her to be exceptionally professional, friendly, empathetic, and welcoming. I highly recommend her services to anyone seeking expert guidance with immigration matters.

Vivian Perfeito is AMAZING!!! We had two previous immigration attorneys who failed us miserably and we were ready to throw in the towel. Our Realtor, Bruno Silva recommended Vivian and we decided to give it one last shot. She exceeded expectations and seamlessly helped us obtain our D7 visa and residency card. She accompanied us to the appointment, spent time managing our difficult case and was kind, professional and lovely to work with. Vivian is a ROCK STAR, i would recommend her to anyone going through this process. She is very intelligent, organized, a good communicator, and answers emails quickly. Our only regret is not finding her a year ago!

I took a chance with going to see Vivian because I am hesitant about finding someone online. But, not knowing many people in PT, and after seeing Vivian speaking confidently and concisely on YouTube links and sharing knowledge generously, I made an appointment and went to see her about my current and future residency status. Vivian is a warm and intelligent lawyer, and gave me quality time, and quickly gained an insight into what would be the best way forward for me. We have just started the process but I feel confident she knows her stuff, and has my best interests at heart, a rare quality to find in any person.

Hello my name is Randy Rava. I decided to move to Portugal 🇵🇹. I found Vivian Perfeito on internet. She is worth every penny. Vivian was there for me every step of the way. Her fees are very low, she was always there for me and she always answered my emails and gave me good direction. She is very honest and kind. She put in much more time with me and helped me in many ways. If you want to immigrate to Portugal 🇵🇹 without the help of a lawyer it would be foolish because of the many mistakes that you would make that would cost you valuable time and money. I found Vivian Perfeito and she is a blessing because she knows exactly what to do at every point in the process, her fees are very reasonable and she is very honest and reliable. Without her knowledge of Portuguese law I would have made mistake after mistake and would never have even known it. I highly recommend Vivian Perfeito Advogada extrordinare the finest most skilled lawyer in all of Portugal.
