The federal government announced in April 2025 a relaxation of the tax deductibility of plug-in hybrids, particularly aimed at the self-employed. These cars would again be tax-deductible for a longer period from 2026, and at higher percentages than previously envisaged.
For hybrids ordered in 2026, a maximum deductibility of up to 100% will apply for the entire lifespan, decreasing to 57.5% for orders in 2029. From 2030, the deductibility will disappear. The deduction percentage will still depend on CO₂ emissions: up to 40 grams per kilometer entitles to full deduction; between 50 and 75 grams, this will be limited to 75%.
The limit for so-called “fake hybrids” has also been relaxed: from 50 to 75 grams of CO₂ per kilometer. This should prevent many models from being excluded under the stricter Euro 6e bis standard, which will come into effect in 2026 and estimate CO₂ emissions more realistically – but also significantly higher.
In early June, the European Commission indicated that this relaxation contradicts Belgium’s climate commitments. Without adjustment, there is a risk of losing up to 282 million euros in European subsidies. The measure is therefore being reviewed.
In response, the federal government decided to limit the tax relaxation to self-employed individuals with a sole proprietorship. Employees and company directors are excluded from the favorable regime.
The federal government has tried to make the transition to plug-in hybrids more attractive through a tax relaxation. However, due to the intervention of the European Commission, the measure was scaled back to sole proprietorships only, significantly limiting the scope of the plan.
