Taxable benefits and impact on net salary in Belgium
Beyond cash salary, the employer can grant benefits in kind: company car, mobile phone, laptop, meal vouchers, housing, etc. These benefits are largely subject to social security and withholding tax, like ordinary salary. They add to the monthly taxable gross.
1. Company car
The benefit in kind (BIK) for private use of a company car is computed under an official formula: 6/7 × catalog value × CO2 coefficient × age coefficient. The amount is monthly, added to taxable gross, subject to the employee social security contribution (except a specific solidarity contribution) and withholding.
The minimum car BIK is revised yearly (around €1,600/year in 2024). Electric vehicles benefit from a minimum CO2 coefficient, reducing the BIK.
2. Mobile phone, computer, internet connection
Private use of an employer-provided mobile, smartphone, tablet or laptop is a lump-sum taxable benefit: €3/month per device for a mobile/smartphone, €6/month for a laptop, €5/month for a home internet connection.
These lump sums are added to taxable gross but their impact on net is modest (a few euros per month).
3. Meal vouchers
Meal vouchers benefit from a favorable tax regime: the employer contribution is exempt from social security and withholding if three conditions are met — maximum employer contribution of €6.91/voucher, minimum employee contribution of €1.09/voucher, and one voucher per worked day maximum.
Beyond the limits, meal vouchers become a taxable benefit. Most employers respect the conditions to avoid taxation.
4. Housing, heating, electricity
If the employer provides housing to the worker (caretaker, representative function), the benefit is lump-sum valued based on the indexed cadastral income of the property (official formula).
Free heating and electricity, when provided, are also lump-sum valued (annual amounts varying based on management function or not).
5. Cumulative effect on net
For a manager with a company car (BIK €4,000/year), mobile + laptop (€108/year) and meal vouchers within the lump sum, the net impact is mostly due to the car: around €1,600/year additional withholding at a 50% marginal rate.
Computing gross/net with benefits requires adding the BIK to the monthly gross entered in this tool. For a complete calculation including the car solidarity contribution and sector-specific particularities, contact Paycore.
