Portugal ISV calculator for imported cars
Calculate an indicative 2026 ISV amount from documented vehicle characteristics. The calculator runs locally without collecting adverts or sending the form to an AI provider.
Information for EU-registered passenger cars imported to mainland Portugal. An estimate is not a tax assessment or a binding transport quote.
What determines ISV?
For the supported EU passenger-car scope, the calculation combines an engine-capacity component and an environmental component. Fuel, NEDC or WLTP emissions, first registration and the assessment date matter. Diesel particulate emissions and qualifying hybrid conditions can change the amount.
Do not guess favourable eligibility
A battery electric vehicle and a plug-in hybrid are not the same tax category. A plug-in reduction depends on the applicable registration period, electric range, CO₂ and, where relevant, Euro 6e-bis evidence. Use homologation documents, not the advertised range or commercial badge. The result excludes VAT, annual IUC, transport and registration costs.
