Group insurance

If the employer covers the full premium, it is not included in payroll calculations. If both employer and employee contribute, the employee’s portion is subject to payroll deductions, reducing taxable income.

Company car

Different legal frameworks regulate the taxation and employer-provided benefits of company cars. The tax treatment depends on factors such as CO₂ emissions, fuel type, and private use. Contact your payroll consultant for guidance.

Meal vouchers

Employers can contribute to meal vouchers up to a legally defined limit per cheque. Employees must contribute a minimum amount. Contact your payroll consultant for current contribution thresholds.

Monthly commission income

Any commission-based earnings are fully subject to income tax and social security contributions.

Monthly premiums

Additional performance-based compensation is taxed as part of the employee’s salary.

Other benefits in kind

Certain non-cash benefits, such as housing allowances or stock options, are subject to taxation and social security deductions.

Employers in Belgium contribute significantly to social security, covering pensions, health insurance, workplace accidents, and unemployment benefits. The rates vary by sector and employee category.

---

Employee Contributions

Employees also contribute a portion of their salary to social security, primarily for pensions, healthcare, and unemployment benefits.

---

Pension Contribution Ceiling

In 2024, the pension contribution ceiling is €116,554.16. Beyond this limit, no additional pension contributions are deducted from an employee’s salary, but other social security contributions may still apply.

Belgium’s social security system ensures financial stability and comprehensive protection for employees while helping businesses remain compliant with national regulations.

Personal Income Tax

Belgium applies a progressive tax system, meaning different portions of income are taxed at increasing rates. The tax brackets and rates for 2025 are as follows:

Income Tax Brackets and Rates (2025)

These rates apply progressively, meaning each rate is charged only on the portion of income within that bracket. For example, if a person earns €50,000 in taxable income, the first €15,200 is taxed at 25%, the next portion up to €26,830 is taxed at 40%, and so on.

Basic Tax-Free Allowance

For 2025, individuals are entitled to a tax-free allowance of €10,910, meaning this portion of income is exempt from taxation. Additional allowances may apply based on family status, number of dependents, or other specific conditions.

Municipal Taxes

Apart from federal income tax, Belgian municipalities impose additional local taxes. These typically range between 0% and 9% of the federal tax owed, depending on where the taxpayer resides.

Additional Considerations

• Taxpayers may be eligible for deductions or credits based on dependents, marital status, and specific expenses such as childcare or mortgage interest.
• Some professional expenses can be deducted to lower taxable income.

Since tax policies can change, it’s advisable to check with Belgium’s official financial authorities or a tax professional for the most up-to-date information.
