Portal das Finanças

Your personal account with the tax office at portaldasfinancas.gov.pt. Through it you file your IRS return, see your IMI bills, register a tenancy agreement, issue recibos verdes, change your address and order certificates, for example the Domicílio Fiscal certificate confirming your tax address.
Where you come across it. You log in with your NIF and a password (senha), through Chave Móvel Digital or with your Cartão de Cidadão.
The password is sent by post to the address registered with your NIF: if that is still a foreign address, the letter goes abroad. Some things cannot be done on the portal — changing the parties to a tenancy agreement, changing a property's address, inheritance matters; these go through e-balcão, the tax office's online help desk.
