Modelo 1 IMT declaration: where to get it in Portugal

Independent site: we are not a public authority, and this is not legal or tax advice.

File the Modelo 1 IMT declaration before the deed, online in the Portal das Finanças or at a tax office (Serviço de Finanças) by appointment. One declaration covers one transaction, and payment slips for IMT and stamp duty are issued when you submit it.
