Context & Explainers
The IUC is the Imposto Único de Circulação (IUC), Portugal's annual vehicle circulation tax charged on cars, motorcycles and other vehicles. If you own or import a vehicle as an expat you must pay the IUC each year to the tax office (rates depend on age, engine size and emissions), and recent news says the payment date will be fixed on the calendar.
