ISV Calculator 2026
Estimate the Portuguese vehicle tax (ISV) for any imported car — in seconds, with no strings attached.
Estimate using the CISV Table A in force in 2026. Check the COC for homologation, CO₂, electric range and particles; the tax authority determines the final amount in the DAV.

What is ISV and what drives the amount
ISV is paid once when a vehicle is registered in Portugal. Table A combines engine size and CO₂. Used cars definitively registered in another EU Member State receive the age reduction; diesel may incur a €500 surcharge. EVs are exempt. Hybrid rates apply only when Article 8 conditions are met.
Age reduction for used cars registered in another EU Member State (Article 11)
| 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% |
ISV 2025 vs 2026: what changed
The engine-size and CO₂ rates in Article 7 remain the same in 2026. The State Budget changed eligibility for certain Euro 6e-bis plug-in hybrids: the 25% rate applies only when the statutory conditions are documented. Age reductions apply to used cars definitively registered in another EU Member State; confirm the final amount with the tax authority.
ISV calculation examples for 2026
Scenarios specify engine size, CO₂, origin and age; they are not promises for any particular model. Rounded values.
| New petrol, 1,000 cm³, 110 g/km WLTP | ≈ €246 |
| Used EU petrol, 1,000 cm³, 110 g/km WLTP, >4–5 years | ≈ €140 |
| Used EU diesel, 1,500 cm³, 120 g/km WLTP, >5–6 years, particles not documented | ≈ €1,483 |
| Eligible new plug-in, 1,500 cm³, 45 g/km WLTP, range ≥50 km | ≈ €549 |
| Electric | €0 |
The €500 diesel surcharge may be waived if the COC proves particles <0.001 g/km. EU-used age reductions cover it too. The 25% plug-in rate requires Article 8 eligibility.
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 engine-size and environmental (CO₂) components are combined; a negative environmental result can offset the engine component. The diesel surcharge and hybrid benefits depend on vehicle documents. Age reductions apply to used vehicles from another EU Member State.
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.
Is there an official Finanças ISV simulator?
There is — inside the Portal das Finanças, in the customs declaration (DAV) area, but it requires a login and is built for people already filing the paperwork. Our simulator uses the same current tables and calculates in seconds, no sign-in. The definitive amount is always the one the tax office confirms in the DAV.
Two routes to the same car: import it, or buy it in Portugal with an inspection
Importing from Germany makes sense when the model is rare here or the ISV maths works in your favour. For many everyday cars the smarter route is a car already on Portuguese plates: we inspect it from €150 in the Lisbon base zone (other areas quoted by location; lift checks cost +€100) or find, inspect and negotiate it for you in the €450 package. Send us the listing — we will tell you which route is cheaper in your case.
Pre-purchase inspection — from €150 Inspection cases Import from Germany — €2,000 flat
