Need advice on NIF and what documents to provide Finanças

Hi Tom & All, Welcome 

Tom, you can request the NIF at any tax office or citizen's shop as follows:

1) If you are resident in a EU country, as is/was your case, all you need to present is your identity card /citizen card and proof of address (utility bill) of your residence in Europe.

2) If you are resident in a country outside the EU, you will have to appoint a tax representative in Portugal, who must be a Portuguese citizen or have permanent residence in Portugal. For example, he may be a Portuguese accountant/solicitor, or someone who you know and trust.

But since you have already sold your house in Belgium and are now in Portugal, why not ask your landlord who rented you the room in Portugal to be your tax representative, or someone you know, even if expat, but living in Portugal? Or then hire a Portuguese accountant to make that request on your behalf through the e-balcão facility:

If you give your old address in Belgium, where now lives someone you know little and with whom you probably don't have any relationship, it is not a good idea, because that person in Belgium will receive correspondence from the Portuguese Tax Authority that is addressed to you (such as passwords to access the finance portal...)

Attention:
due to the pandemic, you have to make an appointment by phone 217 206 707
