# Belgium mandatory mobility budget implementation > Live situation record from CLSTR: https://clstr.news/situations/belgium-mandatory-mobility-budget-implementation > Updated: 2026-09-15T11:40:34.000Z. Sources: 5. Developments: 2. Belgium is preparing for a 2027 mandate requiring employers with more than 50 staff to offer a federal mobility budget as an alternative to traditional company cars. Initial surveys of employers suggest low employee interest in the budget, with estimates that only 26% of workers might opt for it. Employers anticipate that those who do switch will likely use the funds for electric vehicles, housing reimbursements, or sustainable transport. While some large companies have already implemented the budget, others are still in the preparation phase, and some have expressed hope for a postponement of the requirement. Recent findings indicate significant uncertainty among the workforce, with over 80% of employees reportedly unfamiliar with the budget and 73% stating they have received no explanation from employers. This lack of information has created doubt regarding whether the budget is more or less financially advantageous than a company car. Concurrently, the fiscal landscape for company vehicles shows a heavy tax burden that varies by engine type. For the 2026 income year, taxes and contributions for petrol cars can reach 89.2% of the vehicle's cost, while plug-in hybrids face a 53.1% load. Fully electric vehicles currently face a lower tax rate of 26.4%, though costs for employers are expected to increase starting in 2027. ## Timeline ### 2026-09-15: Belgium mobility budget and company car tax trends As Belgium prepares for a mandatory federal mobility budget in 2027, studies show high employee uncertainty and significant tax disparities between petrol, hybrid, and electric company cars. 2 sources. https://clstr.news/cluster/belgium-mobility-budget-and-company-car-tax-trends ### 2026-08-26: SD Worx survey: Low employee interest expected for mobility budget An SD Worx study suggests only 26% of employees may opt for the mandatory Belgian mobility budget, with many expected to use it to switch to electric company cars. 3 sources. https://clstr.news/cluster/sd-worx-survey-low-employee-interest-expected-for-mobility-budget --- Cite as: Belgium mandatory mobility budget implementation.
