For many employees, the mobility budget still sounds like a technical HR concept. In reality, it may be one of the most flexible and tax-efficient benefits currently available in Belgium.
Since its expansion in 2022, the mobility budget has evolved from a simple “company car alternative” into a fully-fledged mobility toolbox, and in some cases, even a housing strategy.
Before exploring where and how the mobility budget can be used, it is important to understand how to implement it correctly.
Are you an employer considering the implementation of a mobility budget? This guide walks you through the process step by step.
Here’s what it really offers.
First: What is the mobility budget?
Instead of opting for a traditional company car, employees receive a budget equal to the total annual cost of that car (TCO). This amount can then be allocated across three pillars.
Most people are familiar with Pillar 1 and Pillar 3. The real surprises lie within Pillar 2.
Pillar 1 – A greener company car
Prefer to keep a car? You can. Pillar 1 allows employees to choose an environmentally friendly company car, typically electric or hydrogen.
The benefits:
- Lower taxable benefit in kind for EVs
- Lower CO₂ solidarity contribution
- Alignment with the 2026 deductibility reform
For those who want to remain mobile while future-proofing their choice, this is the logical option.
Pillar 2 – The hidden treasure chest
Pillar 2 is fully exempt from income tax and social security contributions. Every euro spent here delivers maximum net impact.
And its scope is broader than most people realise.
Public transport - Beyond commuting
Train, tram and bus subscriptions can be financed, not only for commuting, but for private travel as well.
Even better: subscriptions may also cover family members living under the same roof.
Tickets within the European Economic Area can be financed too (excluding flights). That romantic train ride to Paris? Covered in full.
Soft mobility, fully equipped
Considering switching to two wheels? The budget can cover:
- Purchase, lease or rental of a bike (including electric bikes and speed pedelecs)
- Maintenance and repairs
- Storage
- Helmets and protective gear
- Bike assistance services
This is not just about commuting. It is about building a mobility setup that fits your daily rhythm.
Shared mobility, scooters and mobility apps
Here’s where it becomes particularly interesting.
Pillar 2 includes shared mobility solutions such as:
- Car-sharing platforms
- Shared bikes and e-bikes
- Electric scooters and steps
- Carpooling solutions
Taxi services and ride-hailing platforms such as Uber or Bolt are also eligible, provided operators comply with regulations.
In other words, occasional city rides, late-night returns or airport transfers can all form part of your mobility strategy.
This is mobility as a service, not ownership.
Yes, you can rent a car for your holiday
This is the feature that surprises most employees.
You can rent a vehicle without a driver for up to 30 days per calendar year. That includes:
- Standard passenger cars
- Vans
- Even motorhomes
That family road trip? A van-life holiday through Scandinavia? Financed through your mobility budget.
And yes, rentals may also be used abroad.
Living close to the office?
If you live within 10 km of your normal workplace, the mobility budget can be used to finance:
- Rent
- Mortgage capital and interest repayments
Tax-free.
For employees who choose proximity over commuting, this effectively transforms mobility into a financial planning tool. A €700 car budget can become €700 net towards housing costs.
Pillar 3 – Cash, but smarter
If part of the budget remains unused, the balance can still be paid out in cash.
It is subject to a special employee contribution (38.07%), but it is not taxed as professional income and is not subject to employer social security contributions.
Although less fiscally attractive than the benefits under Pillar 2, this amount remains more advantageous than gross salary.
Why this really matters
For years, the Belgian company car was the untouchable king of compensation: four wheels, a fuel card and a fixed routine.
The mobility budget has quietly rewritten that narrative.
Because this is not just about transport. It is about financial flexibility. When the same budget can cover your bike, your train pass, your Uber rides, your holiday rental, and even part of your rent or mortgage, it stops being a perk and starts becoming a strategy.
Living closer to work and redirecting that budget into housing? That is not giving something up. That is upgrading.
The mobility budget may not suit everyone. But it now offers a genuine alternative to what was once considered an untouchable company car advantage.
