Frequently asked questions
Can I get a NIF before I arrive in Portugal?
Yes. The online request through the e-balcão is made by a legal representative acting for you with a power of attorney, so you do not need to be in Portugal. Many people use this route because a lease or a bank account requires a NIF early on.
Do I need a tax representative?
According to the Tax Authority's information for foreign citizens, appointing a tax representative is not mandatory when a NIF is assigned to a non-resident. Representation and notification rules have changed over the years and can depend on where you live, so check the current position for your situation on the Portal das Finanças. Check
Does my NIF change when I become a resident?
No. The number stays the same whether you are registered as resident or non-resident. What changes is your address and tax status, which you ask Finanças to update once you meet the conditions for tax residency.
Is the NIF the same as the NISS?
No. The NIF is your tax number, issued by the Tax and Customs Authority. The NISS is your social security number, issued by Segurança Social, and you need it to work.
How much does it cost?
The official pages we used for this guide do not mention a fee for assigning a NIF. Confirm at your appointment or with the Tax Authority's call centre. If you use a representative or an agency, they charge their own fees.
