Your travel budget

What's the Mobility Budget? 

The mobility budget is an alternative to company cars that was introduced by the Belgian federal government in 2019. It allows employees to convert their entitlement to a company car into a yearly budget.

They are free to choose, either in part or in full, among various options organised around three pillars:

• Pillar 1 – Environmantally friendly car
• Electric cars
• Cars emitting a maximum of 95 g/km (this category is likely to be phased out in 2026)
• Pillar 2 – Sustainable mobility and housing costs (explained below)
• Pillar 3 – Cash payment
• The balance at the end of the financial year can be paid after deduction of a special contribution of 38.07%.

How is an employee's Mobility Budget calculated?

The allowance is calculated based on the Total Cost of Ownership (TCO) of the company car. The law provides for two calculation methods: one based on actual costs and the other a flat-rate method. In both cases, the budget amount includes, in particular, the cost of leasing or hire, fuel or electricity costs, insurance, the CO2 solidarity contribution, etc.

In 2025, the minimum mobility budget for an employee must be €3.233 and a maximum of one-fifth of their total salary or €17.244.

Pillar 2 is the most flexible and environmentally friendly

This pillar allows employees to use their budget for alternative mobility solutions or to finance their housing. You can offer your staff a wide range of options, including public transport season tickets, bicycles, scooters, car-sharing, parking, and more.
Expenditure under Pillar 2 is entirely exempt from taxes ansd social contributions for both the employer and the employee (which is not the case for Pillars 1 and 3). 

SNCB-NMBS is your trusted partner for managing your employees’ Pillar 2

With the mobility budget, your employees can choose to purchase a train season ticket for their commute, but they can also access the full range of SNCB-NMBS services for themselves and for all family members living in their household. 

This means that your employees can use their budget to buy:

• a rail season ticket for their partner and/or their child(ren)
• tickets for a family day out by train
• international rail tickets for their holiday
• an SNCB-NMBS parking season ticket at the station 
• a season ticket for STIB/MIVB, TEC or De Lijn

How can I help my employees choose their Pillar 2 plan? 

SNCB-NMBS offers you the option to manage your contracts and orders via the Business Portal. 

Please note that to place orders under your employees’ Mobility Budget, you must take out an SNCB-NMBS Mobility Pack with 100% employer contribution. This is because the Mobility Budget is already tax-efficient, and the government does not allow SNCB-NMBS's 80/20 third-party payment system to apply to these purchases. 

You will then have the flexibility to order train/bus/tram/metro season tickets, train tickets, SNCB-NMBS car parks and more for your employees. 
You will be invoiced monthly and can easily deduct the amount from your employees’ Mobility Budgets, thanks in particular to detailed reports.

Note: for the time being, we offer international tickets exclusively via SNCB-NMBS International's business travel.
