Mobility budget 2026

Corporate mobility has been changing a lot over the past few years. Regulation has been passed to make it more sustainable and flexible. One of those regulations was the mobility budget. Let's dive into it!

What is the mobility budget?

The mobility budget, also known as the legal or federal mobility budget, is a Belgian incentive that allows employees to exchange their company car or their right to a company car for a legal mobility budget. Employees can spend this budget on alternative and sustainable mobility options without paying taxes on it. No taxes? In Belgium? Yes, it's possible!

And it gets even better: for employers, the mobility budget does not entail any additional cost compared to a company car. This is because the legal mobility budget is equal to the Total Cost of Ownership (TCO) of the company car of the employee. This means that all costs of the company car are added up to a budget. Switching to a legal mobility budget is hereby cost-neutral for the employer.

In 2026, the mobility budget must be no less than €3,233 and no more than 20% of the employee’s total gross annual salary, with a hard cap of €17,244. These limits are indexed yearly.

Note: The mobility budget will become mandatory for all companies offering car in their salary packages. Companies will have until 1st January 2027 to comply, and until 1st January 2028 for smaller companies from 15 to 50 employees.

What is the total gross annual wage of the employee?

This includes the following: the gross salary of the employee + tips + benefit in kinds (Meal vouchers, eco vouchers, laptop, phone, insurances...) + premiums.

The gross annual wage doesn’t include holiday payment, allowances for occupational accidents and shares/stocks. This salary base is key to calculating the gross-to-net mobility budget and sets the fiscal boundaries for the maximum benefit available.

What are the benefits of the mobility budget?

By implementing the mobility budget in your company, you can:

Tick.

Reduce your ecological footprint, your CO2 emissions

Tick.

Compose more attractive salary packages

Tick.

Give employees more mobility flexibility

Is my company eligible for the mobility budget?

Companies must meet specific criteria to be able to offer the mobility budget to their employees. Primarily, they need to have made one or more company cars available to at least one of their employees for an uninterrupted period of at least 36 months. This eligibility ensures that the mobility budget can serve as an alternative to the company car system, promoting more sustainable transportation options.

⚠️ Companies that exist for less than 36 months are eligible for the legal mobility budget when they have allocated at least one company car to an employee.

Is my employee eligible for the mobility budget?

Employees can benefit from the mobility budget if they already have a company car or are eligible for one according to the company's car policy. This eligibility is determined by the employer's existing policies regarding company cars.

Previously, there was a requirement that employees had to have had a company car (or be eligible for one) for a certain period before opting for the mobility budget. This waiting period has been abolished, allowing employees to opt for the mobility budget immediately if they are eligible for a company car. 

How to calculate the amount of a mobility budget?

The mobility budget in Belgium is calculated based on the Total Cost of Ownership (TCO) of a company car. This includes not only the purchase or leasing price but also additional costs such as fuel, insurance, maintenance, and taxes. The TCO is used to determine the annual cost of the company car for the employer. Once this TCO is established, the mobility budget amount can be set to that amount.

You can do this TCO calculation very easily by using our free TCO calculator.

Part-time employee? There's no obligation to lower the amount. Although for fairness reasons, some employees do it using the pro-rata method. Read more about how to keep the policy fair for part-time employment here.

What can I spend the mobility budget on?

This budget can be spent on three main categories (also called the pillars) from an environmentally friendly company car (pillar 1) to sustainable transport options or housing costs (pillar 2). The remaining budget that hasn't been spent at the end of the year is received in cash (not subject to standard income tax or social security but is reduced by a fixed solidarity contribution of 38.07%). All expenses in categories 1 and 2 are tax-free if they meet the legal conditions.

Pillar 1: Eco-friendly company car

A mobility budget can still include a company car, as long as it is: 

  • an electric car 
  • a company car where:

The CO2 emission is less than 95g of CO2 per kilometer;

the emission standard for air pollutants must at least correspond to the standard in force for new vehicles or to a later standard;

if it is a hybrid car, the energy capacity of the electric battery must be at least equal to 0.5 kWh per 100 kg of car weight;

The car must score at least as good as the previous company car for the above three conditions

From 1 January 2026, only fully electric cars will be considered environmentally friendly. There is no obligation for the employer to offer Pillar 1.

Plug-in hybrids, even with low emissions, will no longer be eligible under Pillar 1 from 2026 onward, in line with Belgium’s stricter zero-emission vehicle rules.

Pillar 2: Sustainable mobility and housing costs

Employees can choose to spend their budget to buy, rent, lease and maintain an (electric) bike, scooter, hoverboard and more. Employees can also use their budget for parking costs and equipment costs to protect the driver and his passengers and improve their visibility.

Besides that subscriptions for public transport can be covered by the mobility budget. This applies to the employee and his family members living under the same roof. Public transport tickets do not have this restriction.

Shared mobility is also a possibility. This refers to shared cars, bikes & scooters, rental cars (for maximum 30 days) and taxis.

Housing rent and capital and interest on mortgage loans can be financed from the mobility budget. This is if employees live within 10 kilometres (as the crow flies) of their normal workplace or if the employee works more than 50% from home.

Pillar 3: Cash-out

If you have a budget left over at the end of the year, employees receive the surplus in cash. The cash-out is not subject to standard income tax or social security but is reduced by a fixed solidarity contribution of 38.07% (used for social rights, such as pension) making it a favourable mobility allowance compared to regular salary.

Which expenses related to housing costs are covered by the legal mobility budget?

Living close to work is a sustainable mobility solution par excellence. That is why you can finance your rent or interest or capital reimbursements on your mortgage loan with your legal mobility budget if you live within 10 km (as the crow flies) of your normal place of work.

Can allowances be paid on top or within the legal mobility budget?

Depending on the reimbursement history of the company to the employee the bike allowance, the public transport reimbursement, the employer organized carpool reimbursement and the provision of a company bike can be on top or within the legal mobility budget. When is this the case?

  • On top: If an employee has one of the above allowances 3 months before the request of his/her legal mobility budget, the employee can have the allowance on top of the mobility budget. This employee will get therefore by example a legal mobility budget and a bike allowance. The employer is not obliged to give these allowances on top of the mobility budget. It is thus the choice of the employer if this is allowed or not.
  • Within: If an employee didn't receive the allowance 3 months before the request of his/her legal mobility budget, the employee can only get these allowances within the mobility budget. This means that the mobility budget can be used to pay for these commute. The legal mobility budget of the employee will thus by example be used to get his bike allowance.
  • In Mbrella: Our platform At the moment our product can only allow one of the two above mentioned options within one company. The employer needs to decide if every employee gets their allowances within or on top of the legal mobility budget.

This taking into account te above mentioned rules. So the employer can only decide to give the allowance on top, if every employee is eligible for this.
