How to Get a NIF in Portugal as a Foreigner: Step-by-Step (2026)
The NIF (Numero de Identificacao Fiscal) is your Portuguese tax identification number. It is a unique 9-digit number that you need for virtually everything in Portugal: opening a bank account, signing a rental contract, starting freelance work, paying taxes, and even getting a mobile phone contract. If you are moving to Portugal on a D8 visa, applying for residency, or planning to freelance, getting your NIF is the very first step.
