Buying a car is an important decision as a whole series of annual and routine ancillary costs must also be considered. One of these is certainly the annual stamp. But how exactly do you calculate the car tax? Let's find out together.

We are all passionate about cars and we would all like to change our cars as often as possible. Unfortunately, having a car in the family is an expensive aspect as there is not simply the economic outlay during the purchase phase, but above all there is a whole series of expenses that must be incurred in a routine way throughout the life of the car. .

And it is no coincidence that long-term rental for private individuals is becoming a widespread practice as it allows to contemplate a whole series of costs that would normally be incurred by the owner, within the monthly fee. In fact, people who choose the long-term rental formula also have ordinary and extraordinary maintenance, auto liability insurance and above all the # car tax as part of the monthly fee.

This last aspect is one of the most controversial situations that politics has very often proclaimed to want to eliminate. Despite everything, we still find it present in the annual appointments that every motorist must remember.

In fact, the car tax is a tax that must be paid every year in order not to face even quite important penalties.

But how is the car tax calculated?

The car tax is related to the kilowatts , which are connected with the engine. The greater the power of our engine, expressed in horsepower and consequently in kilowatts, the greater the stamp duty we pay . Therefore, if we have purchased a small car of small displacement with contained performance, we will pay a low road tax. If, on the other hand, we have chosen to buy a performance car with a high thrust and acceleration capacity, therefore with an important number in terms of horsepower and kilowatts, we will certainly pay an important car tax.

To find out the power in terms of kw of our car we must observe the vehicle registration document in which the data is present. However, in the event that the number of kw is not present in the vehicle registration document, but only the number of horsepower expressed by the engine, we should divide the number of horsepower by 1.35.

After knowing the kilowatt level in our car, we need to know the environmental class of the vehicle . We therefore need to know if we are facing a 0.1, 2, 3, 4, 5 or 6 euro car.

The concept is this: the older the car and the more it tends to be Euro 0, the more it will pay.

Euro 1 cars will pay a minimum of € 2.9 per kW if the engine has an output of up to 100 kW, and € 4.35 if the connected engine has an output greater than 100 kW.

As our car gets newer and newer, the prices will drop. In fact, among the Euro 2 cars it is possible to have a price range between 2.8 and 4.2 € per kw.

For Euro 3 cars you can go from 2.7 to 4.05 € per kw.

For cars at the end of € 4, 5 and 6, a rate of between € 2.58 and € 3.87 per kw is expected.

But if we do not want to go too crazy in the calculation and we want to be precise to the hundredth, our advice is to go to the site of the Inland Revenue and click on the "car tax payment" tab. At this point, simply indicate the type of vehicle, enter the license plate number and know the payment situation.

As an alternative to the Revenue Agency website, the ACI website is also an excellent place to find information and to be able to calculate our car tax in a precise and fast way.

But be careful! Let's remember to pay it every year, otherwise we would have to face heavy penalties for all late payments.
