How Tax Brackets Work

This calculator estimates Netherlands Box 1 income tax for 2026. It starts with total Box 1 income, subtracts deductible amounts to get taxable income, applies the tax brackets, then subtracts the general tax credit and optionally the labour tax credit.

Your gross tax comes from the bracket calculation. Your final tax is what remains after credits. That is why your final tax can be much lower than the amount produced by the brackets alone.

Core Flow

Total income = employment income + other Box 1 income Taxable income = max(0, total income - deductions) Gross tax = tax from all applicable brackets Final tax = max(0, gross tax - general tax credit - labour tax credit)

Marginal vs Effective Rate

Your marginal rate is the rate on the next euro of taxable income. Your effective rate is final tax divided by total income. The effective rate is usually lower because not all income is taxed at the top rate and credits reduce final tax.

Frequently Asked Questions

Why is this not a multi-country calculator?+
Because tax brackets, thresholds, and credits are country-specific legal rules. This is not a universal math calculator like a loan or savings tool.
What is the difference between gross tax and final tax?+
Gross tax is the amount created by applying the tax brackets to taxable income. Final tax is the amount left after the applicable tax credits reduce that gross tax.
Do deductions reduce tax directly?+
No. Deductions first reduce taxable income. That lower taxable income then flows through the tax brackets and may also affect how much credit remains available.
Why is labour tax credit optional here?+
Some users want to see the tax bracket result with and without that credit. The switch lets you compare the difference without changing the rest of the structure.
