Frequently asked questions
Can I obtain a NIF entirely online?
In some cases, the application can be prepared remotely and submitted electronically by a representative. Eligibility and the route depend on residence, documents and current Tax Authority rules.
Do I always need a tax representative?
Not necessarily. A legal representative submitting the application and a tax representative for future obligations are different roles. The need for tax representation depends on residence and whether you establish a tax relationship in Portugal.
Does the power of attorney need a certified signature?
The Tax Authority requires signature recognition for certain applications through a representative, subject to specific exceptions such as a power granted to a lawyer or solicitor identified in that capacity.
How much does a NIF cost?
The Tax Authority does not charge for assigning a NIF. Nowtary charges only the professional services listed in the quote, plus any certification or third-party services required.
Nowtary does not issue tax numbers and cannot guarantee timing or approval. The Tax Authority may request further documents. We accept a case only after confirming eligibility and suitable representative availability.
