NIF (Portuguese Tax Number)

The NIF (Número de Identificação Fiscal) is Portugal's tax identification number, a unique nine-digit code assigned by the Portuguese tax authority (Autoridade Tributária e Aduaneira) to individuals and legal entities for tax purposes. Required for various administrative, financial, and legal activities in Portugal, including employment, opening bank accounts, purchasing property, and filing tax returns, the NIF serves as the primary identifier in the Portuguese tax system and is essential for anyone conducting business or maintaining financial obligations in the country.
