No, generally you cannot combine both for the same journey. If part of the journey is by bike and another part by car, a combination may be possible. The cycling allowance is €0.35/km in 2026.

How do you calculate mileage reimbursement for professional trips ?▼

For professional travel, reimbursement is based on the official ONSS rate. The formula is: distance (km) × rate (€/km) = reimbursement.

The bicycle allowance is €0.35/km in 2026. It is exempt from tax and ONSS contributions with no distance limit. It cannot be combined with the car allowance for the same route. For mixed trips (bike + train), both allowances can be combined for separate segments.

What does the Belgian mileage allowance exactly cover?▼

The mileage allowance covers costs of using a personal vehicle: fuel, maintenance, depreciation, insurance and taxes. Parking, tolls and standing charges are not included and can be reimbursed separately on a receipt basis.

Does the mileage allowance apply to self-employed workers and directors in Belgium?▼

Yes. A company director can be reimbursed by their company for professional trips at the official BOSA rate. The rate is identical to that for employees (€0.4327/km in Q2 2026). These reimbursements are company expenses, not taxable in the hands of the director.
