Free calculator for expats and cross-border workers in the Netherlands. Enter the number of days you worked in the Netherlands and another country, along with your gross income, to determine your tax residency, income split, estimated tax in each country, and filing obligations under the applicable tax treaty.
How it works
The calculator uses the 183-day rule from bilateral tax treaties to determine your tax residency. Your income is split proportionally based on days worked in each country. Tax is estimated using 2026 brackets for both countries.
