Autoridade Tributária e Aduaneira

What everyone calls the tax authority. Officially it is the Autoridade Tributária e Aduaneira, created in 2012 by merging the former DGCI, DGAIEC and DGITA. “Going to Finanças” means a visit to the local office — the Serviço de Finanças — where you get a NIF, change your address and sort out things that cannot be resolved online.

Where you come across it. NIF, registering a rental contract, tax certificates, registering as self-employed.

Doutor Finanças is a private website about loans and personal finance; despite the name, it has nothing to do with the tax authority.
