What Is The Tax Identification Number (NIF Number) in Portugal?
The Portuguese NIF number also referred to in Portuguese as Número de Identificação Fiscal or the número de contribuinte is a tax identification number in Portugal. Each person gets their own number, consisting of nine digits, and is issued by the tax authorities in Portugal. No matter what you do in Portugal, you’ll use this number in one way or another. Moreover, this number is also found on tax cards and a citizen’s ID card (but more on this later).
Acquiring a NIF number in Portugal is for all intent and purposes free, but you must pay roughly €6.80 for a Portuguese tax card.
