Belgian Gross/Net calculator — Monthly net salary
Compute your monthly net salary under Belgian social law. Based on the 13.07% employee social security contribution and the official professional withholding tax schedule published by SPF Finances, applicable to both blue- and white-collar workers depending on family situation.
How does the calculation work?
- The monthly gross is reduced by the employee social security contribution (13.07%) to obtain the taxable salary.
- The monthly professional withholding tax is computed on the taxable salary using the official SPF Finances schedule for the worker's family situation (single, married with one or two incomes, legal cohabitant).
- Monthly net = taxable − withholding. Dependent children, other dependents and any recognized disabilities reduce the applied withholding tax.
Frequently asked questions
How does one go from gross to net in Belgium?
The monthly gross is first reduced by the employee social security contribution (13.07%) to obtain the taxable salary. The professional withholding tax is then computed on this base, depending on family situation, dependent children and any recognized disabilities. The monthly net is the taxable salary minus the withholding tax.
Is the employee social security rate always 13.07%?
Yes. The employee social security contribution is set at 13.07% of gross salary since 1998. It applies to both blue- and white-collar workers, with no cap.
Does the result include double holiday pay or the 13th month?
No. This calculator shows the net of the ordinary monthly salary. Exceptional premiums (double holiday pay, 13th month, CCT 90 bonus) are taxed separately at an exceptional withholding rate and are not included.
Does the calculator's result have legal value?
No. The result is purely indicative and is not a substitute for an official payroll calculation by a social secretariat. For full payroll management, contact Paycore.
