Residents apply directly with ID and proof of address; non-residents outside the EU/EEA only need a paid fiscal representative once they establish an actual tax relationship in Portugal (owning property, a work contract, VAT-liable self-employment) - not merely to be issued the NIF - and can often avoid that cost entirely by enrolling in electronic notifications instead.
