About DutchExpatTax.com

Professional workspace overlooking Amsterdam canal houses, representing DutchExpatTax.com's expertise in Dutch tax services for expats

Our Mission

DutchExpatTax.com provides free, accurate Dutch tax calculators designed specifically for international professionals working in the Netherlands. We believe every expat should have access to clear, trustworthy tax information without needing to hire an advisor for basic questions.

Our tools cover the 30% ruling, Box 3 wealth tax, and tax refund estimation — the three areas where expats need the most help.

How We Ensure Accuracy

Every calculation on this site is built using official data from the Belastingdienst (Dutch Tax Authority) and Rijksoverheid (Dutch Government). We follow a strict accuracy protocol:

  • Primary sources only — All tax rates, thresholds, and formulas come directly from belastingdienst.nl and rijksoverheid.nl.
  • Cross-validated — We test our calculators against the Belastingdienst's own example calculations ("Voorbeeldberekening") for multiple salary levels.
  • Annually updated — Tax parameters are refreshed every January when the Belastingdienst publishes new year rates.
  • Automated testing — Our calculation engines have comprehensive unit test suites that verify every formula.

Who Built This

DutchExpatTax.com was built by an international professional with firsthand experience navigating the Dutch tax system. Having gone through the process of understanding the 30% ruling, filing jaaraangiftes, and calculating Box 3 taxes, we created the tools we wished existed when we first arrived in the Netherlands.

The site is a passion project, not affiliated with any tax advisory firm, government body, or financial institution. This independence ensures our information remains objective and user-focused.

What This Site Is Not

DutchExpatTax.com is not a substitute for professional tax advice. Our calculators provide estimates based on general rules and may not account for your specific circumstances. We always recommend consulting a qualified tax advisor (belastingadviseur) for personalized guidance, especially in complex situations.

Technology

This site is built as a static website — no personal data is collected through our calculators. All calculations run entirely in your browser. We use no cookies for the core calculator functionality. The site is built with Astro, React, and TypeScript.
