Moving to (or already living in) the Netherlands brings a tax system that works differently from most home countries - a box-based structure, a possible 30% ruling, and treaty relief if you still hold income or assets abroad. This is a map of where to start.
Dutch income tax splits income into three "boxes" taxed separately: Box 1 covers employment and home-ownership income, Box 2 covers substantial shareholdings, and Box 3 covers savings, investments, and other wealth.
Many expats recruited from abroad with scarce, specific expertise can have up to 30% of their salary paid out tax-free - a significant difference in take-home pay that most other countries' tax systems have no equivalent for.
If you still hold property, investments, or income in your home country, the Netherlands' tax treaties with dozens of countries prevent that same wealth or income from being taxed twice - the calculator on this site models relief for 56 treaty countries, each with at least 5,000 residents in the Netherlands.
Do I have to file a Dutch tax return in my first year?
Almost always yes - a year with a mid-year move typically needs the M-form, which covers a partial tax year.
Is this site an official Belastingdienst tool?
No - this is an independent calculator built to make Dutch tax understandable for expats. Always confirm final figures with the Belastingdienst or a registered tax advisor before filing.
What if my home country isn't in the DTAA list?
The calculator models treaty relief for 10 common countries; the underlying logic (exemption vs. credit method) applies more broadly, but you'd want to check your specific treaty's text.
