How do you register a vehicle in Portugal in 2026?

If the car already carries foreign plates, IMT must assign a Portuguese matrícula. For used vehicles, IMT regional services handle type-approval confirmation or homologation, often with Form Modelo 9 and a Category B inspection certificate from a CITV (vehicle inspection centre) when required. You then regularise the vehicle with customs: register in the Automobile Taxation System, file the DAV (Declaração Aduaneira de Veículo), and pay ISV (Imposto Sobre Veículos) within the working-day deadlines counted from entry into Portugal.

After fiscal regularisation, gov.pt guidance gives a limited window to pay the IMT registration fee and request the registration certificate. You then have plates manufactured and fit them. Until that sequence finishes, foreign-plate driving for a settled resident is a risk, not a long-term plan. A NIF and Finanças portal access sit under almost every AT vehicle step.

Portuguese third-party motor insurance is compulsory for vehicles in circulation. Insurers typically want the Portuguese plate and owner identity before they issue a normal resident policy. IUC (Imposto Único de Circulação) is the annual circulation tax owed by the registered owner (or certain lease holders) through Portal das Finanças. In the first registration year, including imports, IUC is due within 30 days after the legal registration deadline; later years follow the plate-month calendar.

Buying a car already on Portuguese plates skips ISV and DAV, but you still complete ownership transfer, insurance, and any inspection the seller's paperwork requires. Compare that cost with living without a car in cities covered by utilities, internet, and transport and living in Portugal without a car. Your licence rules are separate from the vehicle file: finish convert a driving licence on the IMT Carta path that matches your passport.
