Calculations use 2026 Box 1 rates (35.75% / 37.56% / 49.50%) and assume standard working-age employment. The 30% ruling is modelled as a flat 30% tax-free allowance for the full 5-year term (the previously legislated 30-20-10 step-down was reversed for 2026); it drops to a flat 27% from 2027 onward, which this calculator does not model. Eligibility for the ruling (recruitment from abroad, specific-expertise salary threshold, prior residency distance test) is not verified by this tool. Does not account for the general tax credit, employment tax credit, health insurance premium (ZVW), pension contributions, or Box 2/3 income. For precise advice consult a Dutch tax adviser or the Belastingdienst.
