Portugal has become one of the most popular destinations for expats, and the system reflects that. Your NIF (tax identification number) is the single most important document; you need it to rent a flat, open a bank account, and register for anything else. It can be obtained on the same day at any Financas office or consulate abroad.

Without it nothing proceeds: no bank account, no rental contract, no salary payment, no utility connection. EU citizens obtain it at any Tax Office (Financas / AT, Autoridade Tributaria e Aduaneira) office, free of charge, usually the same day. Non-EU citizens not yet resident in Portugal must appoint a fiscal representative to obtain it before arriving; a specific requirement that catches many people off guard.
