The ISV (vehicle tax) is paid once when you import or register a car in Portugal. It depends on engine size and CO₂ emissions (WLTP), with a reduction for the vehicle's age. This calculator gives an estimate for the main cases — the official figure is set by the Tax Authority. It includes the €500 diesel surcharge (particulates) and, in our tests, matches the AT simulator on the common cases.

How we calculate ISV

We apply the official ISV (vehicle tax) tables: an engine-size component plus a CO₂ (environmental) component, an age-based reduction and the €500 particulate surcharge — following the Autoridade Tributária tables, cross-checked June 2026.

No need to take our word for it: our calculation is open source (MIT). See exactly how it works, verify the numbers, or run it on your own site.
