Importation/Registration
The easiest way of acquiring a vehicle with valid Portuguese registration documents is to purchase a new vehicle from an authorised agent in Portugal who will register the vehicle for you. This has the added advantage of having agents close by to provide service, guarantees, and spare parts. However, importation is an option and there can be tax advantages for new residents from within the EU who import a vehicle they have owned for more than 12 months. You cannot have a foreign licenced vehicle in Portugal for over 6 months in a year, after that time you need to legalize the vehicle by importing it. In order to do the car Importation you should follow these steps: Firstly, to use the vehicle legally whilst the importation process is underway, the owner should apply at the Customs for a long-term permit Guia de Circulação. In the same place the owner will, when applicable, apply for exemption or determination of vehicle tax. The vehicle will then be registered with IMTT and the Documento Único (Car Document) will then be posted to you.
