How to Use the Netherlands Income Tax Calculator
The Netherlands Income Tax Calculator computes Dutch take-home pay under the Box 1 income tax system, applying the heffingskorting (general tax credit) and arbeidskorting (employment tax credit), plus mandatory social insurance premiums for the 2025 tax year.
Enter your gross annual salary (bruto jaarloon). The calculator applies the two-bracket Box 1 system (37.48% for income up to €75,518; 49.5% above), then deducts the tax credits that phase out at higher incomes, and shows your monthly net salary (netto maandinkomen).
A critical nuance is the '30% ruling' (30%-regeling) for expats: qualifying international employees can receive 30% of their salary tax-free as a compensatory allowance, dramatically increasing take-home pay. This applies for up to 5 years for incoming workers meeting specific criteria. The ruling was reduced from 30% to 30% for 2 years, then 20%, then 10% — though rules may change again.

Frequently Asked Questions
What is the Dutch Box 1 income tax rate?
Box 1 covers employment income and other earned income. The 2025 rates are: 37.48% (includes social insurance premiums) on income up to €75,518, and 49.5% on income above that threshold. These rates include both income tax and national insurance premiums (AOW, ANW, WLZ) bundled together.
What is the 30% ruling (30%-regeling)?
Expatriates recruited from abroad (outside a 150km radius of the Dutch border) may qualify for the 30% ruling, allowing them to receive 30% of their gross salary tax-free as an extraterritorial cost allowance. The ruling is valid for up to 5 years. From 2024, it's transitioning to 30% for the first 20 months, 20% for months 21-40, and 10% for months 41-60.
What are Box 2 and Box 3 in Dutch taxation?
Box 2 taxes income from a substantial interest in a company (5%+ shareholding) — dividends and capital gains from your own company. In 2025: 24.5% on the first €67,000 and 33% above. Box 3 taxes notional returns on savings and investments based on a deemed return (fictief rendement) — not actual returns. Each 'box' is taxed separately and losses cannot be offset between boxes.
How does Dutch health insurance work?
Everyone in the Netherlands must have basic health insurance (basisverzekering) from a private insurer. The monthly premium (nominale premie) is around €130–150/month in 2025. Employers pay a nominal premium contribution (werkgeverspremie) separately. The government provides a healthcare allowance (zorgtoeslag) to low-income earners. This is separate from your income tax.
What is the Holidaytoeslag (holiday allowance)?
Dutch employees are legally entitled to a holiday allowance (vakantiegeld) of at least 8% of their annual gross salary, typically paid in May. This means your annual total income is 108% of your monthly contractual salary × 12. Always account for this in salary comparisons — a €4,000/month Dutch salary is equivalent to €4,320/month effective income.
