How to Use the Netherlands Income Tax Calculator
The Dutch income tax system divides income into three separate boxes, each taxed at different rates. Box 1 covers income from work and home ownership; Box 2 covers income from a substantial interest in a company; and Box 3 taxes a notional return on savings and investments. This calculator covers all three for 2025 and also supports the 30% ruling for qualifying expat employees.
Step 1: Enter Your Box 1 Gross Salary
Enter your annual gross salary from employment. In 2025, Box 1 income is taxed at 35.82% up to €38,441 (which includes national insurance contributions — volksverzekeringen) and 49.50% above that threshold. The general tax credit (algemene heffingskorting) and employment credit (arbeidskorting) reduce the final tax payable and are automatically applied by the calculator.
Step 2: Enter Box 2 and Box 3 Income
If you own 5% or more of a company's shares and receive dividends, enter those under Box 2. In 2025, the first €67,000 of Box 2 income is taxed at 24.5% and income above that at 33%. For Box 3, enter your total savings and investment assets — the calculator applies the 2025 deemed return rates (1.03% on savings, 6.04% on investments) to assets above the €57,000 personal threshold, and taxes the notional return at 36%.
Step 3: Apply the 30% Ruling
The 30% ruling allows eligible internationally recruited employees to receive 30% of their Dutch salary as a tax-free allowance. This effectively means only 70% of your Box 1 income is subject to Dutch income tax, significantly reducing your effective rate. The ruling has a five-year maximum duration. Toggle this option on if you or your employer have confirmed eligibility with the Belastingdienst.
Step 4: ZVW Health Insurance Contribution
In addition to Box 1 income tax, employees pay an income-dependent ZVW (Zorgverzekeringswet) contribution. In 2025, this is 5.43% on income up to €75,864. Note that employers pay the ZVW contribution on your behalf, but it is added back to your taxable income — effectively making it your cost. This calculator treats it as a deduction from your gross pay for a clear net pay picture.
Step 5: Review Your Dutch Net Income
The results show your breakdown across all three boxes plus ZVW. Your monthly take-home is calculated from Box 1 salary after income tax and ZVW. Box 2 and Box 3 taxes are annual liabilities you settle when filing your aangifte inkomstenbelasting with the Belastingdienst. Always consult a belastingadviseur for complex situations involving multiple income sources.
FAQ

What are the Dutch tax boxes (Box 1, 2, 3)?
The Netherlands taxes different types of income in separate boxes: Box 1 covers income from employment and home (progressive rates), Box 2 covers substantial interest in a company (dividends), and Box 3 covers savings and investments using a deemed return method. Each box has its own tax rate and rules.
What is the 30% ruling and who qualifies?
The 30% ruling allows qualifying expat employees to receive 30% of their Dutch salary tax-free, reducing their Box 1 taxable income significantly. To qualify, you must be recruited from abroad and meet specific salary and expertise requirements set by the Dutch tax authority (Belastingdienst). This calculator applies the ruling to Box 1 income only.
How does Box 3 wealth tax work in the Netherlands?
Box 3 taxes savings and investments using a deemed return system rather than actual returns. In 2025, assets above the threshold (€57,000 single, €114,000 partners) are taxed at 36% on a notional yield that varies by asset class. The calculator uses the 2025 deemed return rates set by the Belastingdienst.
What is ZVW (Zorgverzekeringswet) premium?
ZVW is the income-dependent health insurance contribution paid by employees. In 2025, the rate is 5.43% on income up to €75,864. This is separate from the flat-rate health insurance premium (nominale premie) you pay directly to your health insurer.
What are volksverzekeringen (national insurance) contributions?
Volksverzekeringen are national insurance contributions covering AOW (state pension), ANW (survivor's benefit), and WLZ (long-term care). They are included in the Box 1 rate — the combined rate in the first bracket includes both income tax and social contributions.
Should I use this to file my Dutch tax return?
No. This is an estimate for planning purposes. Dutch tax returns (aangifte inkomstenbelasting) must be submitted via the Belastingdienst portal at belastingdienst.nl. Consult a belastingadviseur for personalised advice.
