Where to start
Employees should begin with the Netherlands Salary Calculator. Expats on a recruitment package can then run the 30% Ruling Calculator. Freelancers should go straight to the ZZP Calculator. If you own savings or shares, the Box 3 Calculator shows the wealth tax, and anyone leaving a job can use the Transitievergoeding Calculator.
The Dutch system looks complicated because it layers three things: progressive box 1 rates that already contain national insurance, two tax credits that phase out as income rises, and separate regimes for entrepreneurs and wealth. Each page explains the layer it deals with in plain terms.
Frequently asked questions
All of them apply the 2026 Dutch rates and thresholds, and each page lists the exact figures.
Wage tax is withheld per payslip, but the rates and credits are annual, so the calculators work on a yearly basis and divide by 12.
For straightforward employment income the estimates are usually enough. For a BV, foreign income or a ruling application, talk to an adviser.
