🇳🇱Netherlands Income Tax Calculator

Estimate your Dutch income tax in Box 1 for tax year 2025, with rates that include social security contributions. The calculator applies the three Box 1 brackets plus the algemene heffingskorting and arbeidskorting tax credits, and shows your tax bands, marginal and effective rates, and take-home pay. It assumes you are below AOW (state pension) age for the whole year and does not cover Box 2 or Box 3 income. Everything runs in your browser, so your numbers stay private.
