From 1 January 2026, the mobility budget becomes mandatory in Belgium.
But not for everyone, and not immediately.
The obligation only applies to employers who offer company cars on a continuous basis for at least 36 months. The exact deadline depends on the size of your company.

Below, you’ll find an overview of what has already been decided and how to best prepare your organisation.
When do you need to implement the mobility budget?
The federal government has confirmed the principle:
employers who offer company cars will be required to provide a mobility budget.
However, this will not apply immediately. Exemptions and transition periods are foreseen, depending on company size.
Timeline at a glance
Fewer than 15 employees
→ Fully exempt
15 to 50 employees
→ Transition period until 1 January 2028
More than 50 employees
→ Transition period until 1 January 2027
👉 1 January 2026 is the reference date, but the obligation will apply later for most companies.
What does not change (for now)?
The fundamentals of the mobility budget remain unchanged:
- The three pillars remain in place
- Housing costs remain allowed under pillar 2
- The method for calculating the budget does not change
One important clarification has been confirmed:
👉 Only electric cars are allowed
Company cars under pillar 1, and car options under pillar 2, must be fully electric.
Combustion engines and hybrids are no longer eligible.
A broader reform may follow later, but this is separate from the obligation itself.
Already offering a mobility budget? Don’t forget indexation
Do you already offer a mobility budget today?
👉 Make sure to index your existing budget to remain compliant with legal requirements.
What should you do now?
Is your deadline still some time away? Good news: that gives you room to approach this thoughtfully.
Concretely:
- Review your current car and compensation policy
Where are the inconsistencies or potential limitations? - Communicate clearly with employees, in time
Clarity works better than legal jargon. Explain what’s coming, when, and why. - Choose a solution that fits your organisation
Do you need a complex setup with many options and exceptions, or a simple and cost-effective solution? That depends on your size, needs and budget.
At Monizze, we help SMEs turn this obligation into a simple, flexible mobility solution with RewardFlex.
A mobility budget doesn’t have to be complex

You:
- avoid last-minute decisions

- give employees more freedom of choice
- contribute to more sustainable mobility
Companies that use 2026 as a preparation year:
- remain competitive
- make more informed choices
- increase employees’ net benefit
Setting up a mobility budget doesn’t need to be complicated.
