Both Belgium and Netherlands sit in Europe, but their tax structures take different paths. On a 65 000 € gross, the effective tax burden in Netherlands is roughly 7.8% higher than in Belgium — driven by differences in ONSS vs Volksverzekeringen, bracket structure, and personal allowance.
Same nominal gross applied to both tax systems. Currencies aren't FX-converted — compare structures, not purchasing power.
Belgium has one of the highest effective tax burdens in the world: progressive income-tax brackets reach 50% quickly, and the flat 13.07% employee social-security contribution applies to the entire gross salary. Municipal surtaxes add another 6–9% on income tax. Net take-home is typically 55–60% of gross.
The Netherlands combines income tax and national insurance into a single Box 1 rate that hits 49.5% above €76,817. The general tax credit (algemene heffingskorting) and labour tax credit (arbeidskorting) significantly reduce the effective rate for low-to-middle earners. Expats may qualify for the 30% ruling.
