ABOUT THIS TOOL
How the tax brackets calculator works
What it shows
The box 1 income tax brackets for the year, and your personal marginal and average tax rate based on your gross income.
How to read the result
Your marginal rate is the tax on your next euro. It is often higher than the bracket rate because tax credits shrink as your income rises.
Who it's for
Anyone weighing a pay rise, extra hours or freelance income who wants to know what they will really keep.
Good to know
The bracket rates combine income tax and national insurance premiums. Different rates apply once you reach the state pension age.
Tax bracket questions
Quick answers about Dutch income tax rates.
How many tax brackets does the Netherlands have?
Box 1 has three brackets in 2026. The calculator shows the exact thresholds and rates for the year you select.
What is the difference between marginal and average rate?
The marginal rate applies to your next euro. The average rate is your total tax divided by your income, and is usually much lower.
Why do I keep less of a pay rise than expected?
As your income goes up, the general tax credit and the employment tax credit are reduced, which raises your marginal rate.
Do these rates apply to freelancers?
Yes. Freelance profit is box 1 income too, after entrepreneur deductions such as the self-employed deduction and the SME profit exemption.
