Netherlands Income Tax Estimator (Box 1)
Estimate your yearly Dutch income tax using progressive rates and optional tax credit assumptions.
This is a simplified calculator for Box 1 income tax. Municipal taxes, healthcare premiums, box 2/3 taxes, and special situations are not included.
How Dutch income tax works
The Netherlands uses a progressive income tax system. That means higher portions of income are taxed at higher rates. Most employees and freelancers mainly deal with Box 1, which includes salary, pension income, and business profits (with specific rules and deductions).
The Dutch “three-box” model at a glance
- Box 1: Income from work and home ownership (progressive rates).
- Box 2: Income from substantial interest (such as owning at least 5% of a company).
- Box 3: Income from savings and investments (taxed via deemed return rules).
This calculator focuses on Box 1 tax rates and gives a fast estimate for budgeting, salary negotiation, and tax planning.

Quick planning tips for Dutch taxpayers
1) Track deductible costs early
Keep receipts and maintain clean records throughout the year. Waiting until filing season often means missed deductions.
2) Check your effective tax rate, not just the marginal rate
Your marginal rate applies only to your next euro of income. Your effective rate shows the true tax burden across your total income.
3) Recalculate after salary changes
If you receive a raise, bonus, or switch from employment to self-employment, run a new estimate. It helps avoid unpleasant surprises when filing taxes.
