For many Belgian companies, mobility policies have long revolved around one key benefit: the company car. But that model is being seriously challenged.
Between environmental pressures, rising traffic congestion, and the growing expectations of younger generations, the way employees commute is changing – and fast.
One solution is gaining momentum: the mobility budget, with key legislative changes expected in 2026.
What is the mobility budget?
The federal mobility budget, introduced by the Belgian government in 2019, allows employees entitled to a company car to exchange it for a yearly budget to spend on more sustainable mobility options.
These options are split into three categories:
- Greener vehicles (e.g. electric cars with low CO₂ emissions)
- Sustainable transport and alternatives (public transport, cycling, walking, carpooling, etc.)
- A cash payout for any unused balance (heavily taxed)
The mobility budget is voluntary today, but this won’t last much longer.
2026: from optional to mandatory
In 2025, the government announced that companies offering company cars will be legally required to provide a mobility budget by 2026.
Although this obligation was initially planned to enter into force on January 1, 2026, its implementation has been officially postponed. According to Renta, the Belgian federation of vehicle leasing companies, the mandatory mobility budget will enter into force at the earliest from July 2026 (source).
This postponement does not change the direction of travel. It simply gives employers a limited additional timeframe to prepare for a structural change that will impact HR policy, compensation strategy and employee communication.
In that context, the question is no longer “Should we offer a mobility budget?” but rather “How will we implement it in a way that is compliant, fair and aligned with our HR strategy?”
Why HR should care about the mobility budget
Here’s why HR leaders and employers need to get ahead of this transformation:
1. It boosts talent attraction & retention
Millennials and Gen Z employees expect flexibility and value sustainability. Offering a mobility budget – especially when combined with an employer-sponsored bike or public transport – is a clear signal of modern, employee-centric values.
2. It reduces absenteeism
Studies show that cycling to work can reduce sick leave by up to 4.5 days per year, thanks to better physical and mental health.
3. It strengthens employer branding
Companies that support low-carbon commuting are perceived as more innovative, responsible and inclusive. That image has a direct impact on recruitment and engagement.
Why starting with a bike plan makes sense
Many companies hesitate to jump directly into the complexity of a full mobility budget. That’s why we recommend starting with a bike plan first.
A company bike plan:
- Is easy to launch and manage (especially via leasing)
- Is budget-neutral or even cost-effective
- Helps employees discover new commuting habits
- Creates a smooth transition path toward the full mobility budget
- Preserves more options: once a mobility budget is in place, salary sacrifice schemes for bike leasing are no longer allowed — meaning less flexibility for both employer and employee
In short: it’s a smart first step.
