Electric car in Wallonia: taxes, charging and incentives in 2026

My father texted me last week from Namur: "I heard the registration tax changed in Wallonia. Is it more expensive for electric cars now?" My parents live in Wallonia and I drive the Brussels–Namur route on the E411 almost every weekend. This question comes up at every family dinner. And the answer deserves a proper look at the numbers.

How much does the registration tax cost for an EV in Wallonia since the July 2025 reform?

Wallonia abandoned its old registration tax system based solely on fiscal horsepower on 1 July 2025. The new formula factors in weight, emissions and an energy coefficient specific to each powertrain.

For a 100% electric vehicle, the formula simplifies to: TMC = MB × (MMA / 1,838) × C. The CO2 factor drops out (logically: an EV emits 0 g/km). The energy coefficient C makes all the difference — and it is designed to favour EVs.

In practice, here is what it looks like for the best-selling models in Belgium:

The absolute minimum is EUR 61.50. The Walloon TMC ceiling is set at EUR 9,000 — a figure only the most powerful combustion SUVs reach.

Additional reduction: large families receive a flat EUR 250 rebate on the TMC. From 1 July 2026, this reduction will extend to single-parent families receiving the supplementary family allowance (SPW Finances, 2025).

What is the annual road tax for an EV in Wallonia?

The annual road tax is capped at the minimum rate of EUR 102.96/year for 100% electric vehicles (indexed 2026 amount). This cap applies whether you drive an electric city car or a 400 kW SUV.

Over 5 years, a private EV owner in Wallonia saves between EUR 2,900 and 5,000 in taxes compared to an equivalent diesel. Even the most powerful EV costs less in taxes over 5 years than a modest diesel costs in its first year alone.

Why does Wallonia have no low emission zone?

On the E411 between Brussels and Namur, I don't pass a single LEZ camera. And for good reason: Wallonia doesn't have one. It's the only Belgian region with no emissions-based access restriction.

The Walloon Parliament repealed the regional LEZ decree in April 2024 (SPW, 2024). The decree had planned a zone covering all of Wallonia with a progressive timeline: Euro 1 from 2023, Euro 4 in 2026, Euro 5 in 2028, Euro 6 in 2030. The implementing orders were never published — the system never entered into force.

Unlike Brussels (active LEZ since 2018, diesel Euro 5 banned in 2026) and Flanders (LEZ in Antwerp and Ghent since 2017-2020), Wallonia chose not to restrict combustion vehicle access to its city centres. Some cities are studying local LEZ schemes:

In practice, a Euro 4 diesel can still drive freely anywhere in Wallonia in 2026. This is short-term comfort for current drivers, but an inverted signal compared to the rest of Europe. An EV bought today will never be affected by any future LEZ, regardless of how Walloon legislation evolves.

What is the real state of the charging network in Wallonia in 2026?

This is the sensitive point. Wallonia started from behind.

The Walloon lag is measurable. At the start of 2026, Wallonia held 13.6% of Belgium's public charging points while representing 55% of the territory and 32% of the population. Flanders had 43,000 charging points at the same date.

Two factors are changing the picture in 2026. First, the contract between the Walloon Region and Engie Vianeo provides for 2,926 charging points across 1,625 22 kW stations distributed throughout Wallonia (SPW Mobility, 2025). Second, 1,724 municipal charging stations are being deployed across Walloon municipalities by end 2026.

On Walloon motorways, fast charging stations are in place:

In practice, on the Brussels–Namur drive (70 km), I have never needed to charge en route. But for Brussels–Arlon (190 km) in winter at 130 km/h, a charging stop is still necessary with most mid-range battery EVs. The Ionity stations on the E411 near Wanlin and Tellin cover this need.

What advantages do Walloon professionals and self-employed workers get in 2026?

Tax advantages for company cars are federal — they apply in all three regions. But Wallonia adds its own scheme.

Federal 100% deductibility (last year)

An EV ordered in 2026 by a company or self-employed worker is 100% deductible — leasing costs, maintenance, insurance and energy included. Last year at full rate.

The minimum BIK for a company EV is EUR 1,690/year. The employer CO2 contribution is EUR 33.93/month, compared to EUR 120 to 180/month for a diesel (×4 multiplier since 2026).

Easy'Green: the Walloon scheme for businesses

The Easy'Green programme from the Walloon Region targets Walloon businesses and self-employed workers. It covers the acquisition of charging infrastructure with aid of 15 to 45% of eligible expenses, with a ceiling of up to EUR 1 million per project (SPW Economy, 2025).

This is a lever that Walloon businesses underuse. An independent garage in Liège installing 4 × 22 kW chargers at EUR 8,000 can recover up to EUR 3,600 via Easy'Green, on top of the federal deductibility.

How does Wallonia compare to the other two regions?

Wallonia stands out by the absence of a LEZ (less pressure on combustion drivers, but less incentive to transition) and a charging network in accelerated catch-up. Its TMC is more variable than the other two regions — a modest EV pays less, a very powerful EV pays more.
