Kilometer Taxation in Practice: Impact on Your Budget and Car Financing
Kilometer-based road pricing is no longer just a theoretical idea. In 2026, the debate around kilometer taxation is back in the spotlight and could significantly influence the total cost of using your vehicle, your daily commuting habits, and even the way you finance your car.
Understanding how such a system works, who it affects, and what alternatives exist is essential if you want to keep control over your mobility budget. Below, discover how kilometer taxation is tested in practice, its objectives, criticism, and how smart car financing can help you adapt.

Test Phase of Kilometer Taxation
A panel of 1,200 motorists takes part in a practical test where each kilometer traveled is priced according to the type of road, the time of day, and the characteristics of the vehicle. The objective: measure the real impact of a “pay-per-kilometer” system on behavior and congestion.
Kilometer Taxation in a Nutshell
The tested mechanism aims to charge a specific tax amount for each kilometer driven. In urban areas, driving could cost up to 9 cents per kilometer, compared with 5 cents on the highway and 6.5 cents on other roads. The rate varies according to traffic peaks and the type of road taken.
The tax is highest during peak hours — typically from 7 a.m. to 9 a.m. and from 4 p.m. to 6 p.m. — while motorists can drive for free between 10 p.m. and 5 a.m. During peak hours, the amount can reach 9 cents per kilometer in urban zones, making daily commuting significantly more expensive for frequent drivers.
In practical terms, the system relies on an onboard GPS device that records the distance traveled, identifies the type of road, and calculates the applicable price per kilometer in real time. On the screen, the driver can see the vehicle’s location as well as the current rate for the road being used.
A Long-Standing Mobility Project
Kilometer taxation is not a new idea. It stems from an agreement reached in 2011 between the three Regions on the taxation of heavy goods vehicles and has been considered for over a decade as a tool to better manage road traffic and pollution. Consulting firms such as PwC have developed concrete scenarios, later presented by car importers’ federations like Fébiac.
Initially focused on professional and freight transport, the concept has gradually expanded to private vehicles, with the idea of replacing current flat-rate road taxes and registration taxes with a more dynamic, usage-based system. The goal is to create a fairer and more efficient tax model that directly reflects the use of the road network.
The “Polluter Pays” Logic
The principle behind kilometer taxation is simple and already partially applied via fuel excise duties, VAT, maintenance, spare parts, and even new insurance formulas: the more you drive, the more you pay. Rather than taxing vehicle ownership, kilometer taxation aims to tax its actual use.
This approach is supported by several economic and mobility organizations (Beci, Voka, Touring, VAB, etc.) which see it as a tool to:
- Encourage the use of public transport and alternative mobility solutions.
- Spread traffic outside of peak hours by making off-peak driving financially more attractive.
- Reduce congestion in urban centers, especially chronic traffic jams in and around Brussels.
For motorists, this means that journey planning, route choice, and vehicle type will increasingly influence the total cost of mobility. It becomes essential to anticipate these changes when buying and financing a car.
A Controversial Reform: Who Really Pays?
Public opinion remains highly divided. On social networks, comments are multiplying, and online petitions such as the petition against the km tax have collected tens of thousands of signatures. Many opponents denounce a system perceived as discriminatory for households forced to travel long distances.
The main criticism: kilometer taxation would particularly affect people who live far from large cities and drive many kilometers each year, often lower-income households who chose to live further away to reduce housing costs. For them, the additional cost per kilometer could become a heavy and poorly anticipated burden.
Politically, the topic is sensitive. Many elected officials and a large number of parties express reservations, especially in the run-up to elections. However, from a strictly environmental and mobility management standpoint, the idea of encouraging drivers to drive less, or differently, remains defensible and aligned with long-term climate objectives.
How Smart Car Financing Helps You Adapt
More Advantageous APR for Newer Cars
A car financing for a new vehicle generally offers a more advantageous APR than financing for an older used car. A car is considered new for financing purposes when it is less than three years old, which allows you to benefit from particularly competitive rates.
In the context of kilometer taxation, driving a more recent vehicle can be doubly beneficial: lower fuel consumption, less maintenance, and more attractive financing conditions, helping you offset part of the additional mobility costs.
Better Control Over Your Mobility Budget
By choosing a financing solution tailored to your situation, you can spread the cost of your vehicle over time and preserve a margin in your budget to absorb variable expenses such as fuel, taxes per kilometer, and maintenance.
Well-structured monthly payments make it easier to anticipate your total cost of mobility in 2026 and beyond, even if taxation evolves. The key is to avoid over-financing your vehicle and keep a realistic and sustainable repayment plan.
Flexibility and Security in a Changing Context
The possible implementation of kilometer taxation adds a new variable to your financial planning. Opting for a balanced car loan, adapted to your income and your travel habits, gives you more flexibility to cope with regulatory changes without jeopardizing your budget.
By combining appropriate financing with smarter use of your vehicle (optimized routes, off-peak driving, mixed mobility), you can limit the impact of new taxes while keeping your freedom of movement.
Prepare Your Mobility Budget for 2026
Whether kilometer taxation is fully implemented or not, the cost of using your car will remain a central element of your budget. By choosing the right car financing — especially for a vehicle less than 3 years old — you can benefit from a competitive APR and keep maximum flexibility.
