Professional expenses reduce taxable income; they are not a cash deduction from salary. The personal allowance creates a tax credit, rather than moving the tax brackets. Municipal rates vary by town and year.

Questions about Belgium salary after tax
Is this my exact payslip or tax assessment?
No. It is an estimate for the supported profile and selected assumptions. Annual assessment amounts are averaged over twelve months; employer withholding can differ. Voluntary deductions and unsupported benefits can change bank-account pay.
Can I include employer contributions or bonuses?
Enter regular employee cash salary only. Employer contributions are not deducted from it. Bonuses, extra holiday pay, salary sacrifice and unequal payments require separate calculations.
Is my salary stored or sent anywhere?
No. Calculation runs locally in your browser, including Germany’s BMF algorithm. Salary values stay out of URLs, requests, storage, logs and analytics. Changing country or year clears them.
