Road Tax in Portugal

Find out about Portuguese road tax, how it's calculated and how to pay...

Road tax (Imposto Único de Circulação, IUC) must be paid annually on the date that the vehicle was first registered. Drivers are required to keep a receipt as proof of payment.

The amount of tax paid is different for vehicles registered before and after July 2007. Owners of cars registered before July 2007 pay an amount of tax directly related to the age of the vehicle and its cubic capacity. The tax on vehicles registered after July 2007 will also take into account the vehicle's CO2 emissions and the power of the engine.

Road tax can be paid at the local Finanças office or via the Internet at e-financas. A password is needed, which can be requested online (in Portuguese).
