What is ISV and what drives the amount
ISV is the one-off tax paid when legalizing a vehicle in Portugal. It has two components — engine displacement (cm³) and environmental (CO₂ emissions) — and is reduced according to the car’s age. Diesel cars pay a surcharge; EVs are exempt and plug-in hybrids get a 75% reduction.
ISV reduction by vehicle age (official table)
| Age (since first registration) | ISV reduction |
|---|---|
| Up to 1 year | 10% |
| > 1 to 2 years | 20% |
| > 2 to 3 years | 28% |
| > 3 to 4 years | 35% |
| > 4 to 5 years | 43% |
| > 5 to 6 years | 52% |
| > 6 to 7 years | 60% |
| > 7 to 8 years | 65% |
| > 8 to 9 years | 70% |
| > 9 to 10 years | 75% |
| Over 10 years | 80% |
What about IUC? The 2026 annual road-tax table
Besides the one-off ISV, every car in Portugal pays the IUC yearly. For cars registered after July 2007 (category B): an engine-size component + a CO₂ component, multiplied by the first-registration-year coefficient (1.15 for 2010 onwards). Diesel pays a surcharge; EVs are exempt.
| Engine size | Rate |
|---|---|
| ≤ 1250 cm³ | 31,77 € |
| 1251–1750 cm³ | 63,74 € |
| 1751–2500 cm³ | 127,35 € |
| > 2500 cm³ | 435,84 € |
| CO₂ (WLTP) | Rate |
|---|---|
| ≤ 140 g/km | 65,15 € |
| 141–205 g/km | 97,63 € |
| 206–260 g/km | 212,04 € |
| > 260 g/km | 363,25 € |
Examples (registered 2010+):
- 1.0 petrol, 132 g — ≈ €111/year
- 1.5 diesel, 120 g — ≈ €158/year (incl. diesel surcharge)
- 2.0 diesel, 150 g — ≈ €279/year
Official 2026 values (unchanged vs 2024/25). The exact amount is on the AT payment note; pre-2007 cars use the lower category-A table.
Frequently asked questions
What is the ISV?
It is the Portuguese Vehicle Tax, paid once when a car is registered in Portugal. It is based on engine size and CO₂ emissions, with a reduction for the vehicle’s age.
How is the ISV calculated?
The displacement component and the environmental (CO₂) component are added, the age reduction is applied and, for diesel, a surcharge. Our simulator does this automatically.
Do electric cars pay ISV?
No. Fully electric vehicles are exempt from ISV. Qualifying plug-in hybrids get a 75% reduction.
Is the simulator official?
It is an accurate estimate based on the 2026 tables. The official amount is set in the Vehicle Customs Declaration (DAV) on the tax authority portal.
Can you help me import and legalize the car?
Yes. We handle the whole turnkey process — from choosing the car to registration in Portugal. Message us on WhatsApp for a quote.
Do I pay ISV if I move my residence to Portugal?
Not necessarily. A residence transfer qualifies for a full ISV exemption (Art. 58 CISV): you need 6+ months living abroad and 6+ months owning the car, with a free application within 12 months. The annual IUC road tax still applies.
