Specific rules apply to tractors, distinguishing them based on usage, speed, and registration.
The general rule is that tractors are subject to the kilometer fee if they are registration and inspection-required, but significant exemptions apply for agriculture.
Fee
For those tractors that are liable for the fee, the same fee schedule applies as for vehicles.
Liable tractors
Those tractors that are both registration-liable and inspection-liable are subject to the fee.
This applies to tractors that are designed to drive over 40 km/h and are used on public roads.
A tractor refers to a motorized vehicle on wheels and/or tracks that is primarily designed to tow another vehicle and to pull, push, transport, and power implements/work tools.
Exemptions for agriculture
Although a tractor might be considered liable for the fee (for example, due to its speed), there is a specific exemption for tractors used in agriculture. The following conditions must be met for a tractor to be exempt from the kilometer fee:
Use:
The tractor (and its trailer) must be used for agricultural purposes.Owner/Custodian:
Must be registered in the agricultural register with the Directorate of Internal Revenue for VAT registraions classified under ISAT industry classification 1 (Agriculture).Limitation:
The exemption does not apply if the activity is classified as "farm service provision" (or "services supporting agriculture").
Vehicles exempt from the kilometer fee
Several types of vehicles are exempt from paying the kilometer fee:
Vehicles intended for the operation of rescue teams, provided that confirmation is available that the vehicle is listed as such in the vehicle registry and will be used only for the benefit of rescue teams.
Classic vehicles with first registration on January 1, 1965, or earlier, where it is demonstrated that the vehicle never had an odometer, it is not possible to install one, or it is not possible to repair it.
