Frequently Asked Questions
What is an automatic tax return and when do you pay it?
Automobile Tax Supplement (additional fiscal tax on motor vehicles) is an imposed tax introduced by DL 98/2011, art.23, added to the regular toll for vehicles with power exceeding 185 kW. The amount is €20/kW per each kilowatt above the threshold. Paid together with the ordinary toll within the next month after the deadline.
How is vehicle age reduction super tax calculated?
The D.L. 98/2011, Article 23, prescribes increasing reductions based on age: vehicles between 6 and 10 years have a 40% reduction, those between 11 and 15 years have a 70% reduction, and those between 16 and 20 years have an 85% reduction. The superbonus does not apply beyond the age of 20.
Do electric vehicles pay car tax?
Electric vehicles are exempt from the car tax for the first 5 years after registration, under national legislation. After this period, most regions apply permanent discounts or reduced rates - conditions vary by region. Electric vehicles are always exempt from the super tax.
Why does the stamp vary from region to region?
The auto stamp is a regional tax managed by individual regions, which can increase or decrease the rate within national limits. The 17th Fiscal Reform Law of 2026 expanded regional autonomy in taxation matters. This calculator uses a scenario approach: it provides an indicative tariff for the 5 most populous regions and the baseline national rate for others, with a verification notice.
How do I convert horsepower to kW for tax purposes?
To convert horsepower (hp) to kW (kilowatts), divide the value by 1.36 (or multiply it by 0.7355). For example, 300 hp is equivalent to approximately 221 kW. The power in kW is always indicated on the Vehicle Registration Card (section "Maximum Power").
How is it used?
- Insert vehicle power
Indicates the kW (kilowatt) of the engine listed in the Vehicle Registration Card under "Maximum Power (kW)". If you only know HP, divide by 1.36.
- Select Euro class, region and diet
Choose the Euro vehicle class (as indicated on the Vehicle Registration Card), owner's residence region, and fuel type (essential for BEV exemption).
- Year of registration
The year is used to calculate both superbollo reductions for age (DL 98/2011) and exemption from stamp duty for electric vehicles.
- Calculate and interpret the result
Click "Calculate" to get your regional stamp, superstamp (if applicable), and annual total. The result is indicative: always check your region.
What is the self-assessment tax 2026 and how is it calculated?
Car sticker is a regional automobile tax that motor vehicle owners must pay annually. The amount is calculated by multiplying the engine power in kilowatts (kW) by the current regional tariff, which varies based on the Euro class of the vehicle. Regional Italian areas have autonomy to define tariffs within national limits.
Automobile Super Tax, introduced by DL 98/2011 art.23, is a fixed annual tax added to the ordinary tax for vehicles with power exceeding 185 kW. The rate is €20/kW for each kilowatt above the threshold - regardless of Euro class or region. Pure electric vehicles (BEV) are exempt from both tax and super tax forever.
For vehicles with a supermud sticker, the DL 98/2011 regulation provides increasing reductions based on age: 40% between 6 and 10 years old, 70% between 11 and 15 years old, 85% between 16 and 20 years old. Beyond 20 years, the supermud sticker does not apply. This mechanism gradually reduces costs for older vehicles, encouraging the renewal of the circulating automotive fleet.
The 17th legislative decree of tax reform 2026 expanded regional autonomy in managing the auto toll. This calculator uses a scenario-based approach with indicative tariffs for the 5 most populous regions (Lombardy, Lazio, Campania, Sicily, Veneto) and national baseline for others. For exact tariff in your region, always check on local regional site or ACI local office.
Practical example
- Vehicle: 200 kW, Euro 5, Lazio, 2022, petrol
- Bill: $2.58/kWh x 200 kWh x 1.00 (Lazio multiplier) = $516.00
- Superbonus: (200 - 185) kW x 20 €/kW = 15 x 20 = 300.00 € (age 4, no reduction)
- Annual total = 516.00 + 300.00 = 816.00 €
