The ISV: the cost that varies
The ISV (Portuguese vehicle tax) is paid once, when the car gets Portuguese plates, and is assessed by the Tax Authority. It is the sum of an engine-size component and an environmental (CO₂) component, with a €500 surcharge on diesel vehicles, and a reduction for years of use on used cars — from 10% up to one year old to 80% over ten years. This tax is what makes the biggest difference to the total.
Example 1 — gasoline, 1,598 cm³, 120 g/km, three years old
- Engine-size component: €2,769.90
- Environmental component (WLTP): €17.81
- Reduction for three to four years of use (35%): −€975.70
- Estimated ISV: €1,812.01
- Total with the service and the IMT fee: €2,016.91 (€1,812.01 + €159.90 + €45)
Example 2 — diesel, 1,995 cm³, 130 g/km, five years old
- Engine-size component: €4,997.07
- Environmental component (WLTP): €1,094.35
- Particulate surcharge (diesel): €500.00
- Reduction for five to six years of use (52%): −€3,167.54
- Estimated ISV: €3,423.88
- Total with the service and the IMT fee: €3,628.78 (€3,423.88 + €159.90 + €45)
Both examples are used cars coming from the European Union, calculated in October 2026 with the current tables, using the ISV calculator on this website. Age counts up to the date of the DAV, so the reduction bracket changes as time goes by. The final amount is always the one set by the Tax Authority. If the car comes from outside the European Union, the math is different — see the guide on ISV for cars from the EU and outside the EU.
After you get plates
Every year there is the IUC, paid in the month of registration and calculated from the car's original date of first registration. And insurance: first on the foreign plates, then on the Portuguese ones — see our car insurance.
