Income Tax Estimator
Estimate progressive income tax using your own bracket thresholds.
Tax brackets vary by country and change yearly — enter your own bracket thresholds and rates below. The defaults are a generic example, not real tax law for any country.
About this tool
Most income tax systems are progressive: different slices of your income are taxed at different rates, so your top rate isn't applied to your whole income — only to the portion inside that bracket. Because bracket thresholds and rates differ by country and change every year, this tool lets you enter your own bracket structure rather than guessing at outdated numbers.

Frequently Asked Questions
Brackets vary by country, filing status and tax year, and change often — baking in specific numbers would go stale and could mislead you. Enter your own current brackets from your tax authority for an accurate estimate.
That's the point of a progressive system — only the income inside your top bracket is taxed at your top rate. Everything below it is taxed at the lower rates for those brackets, which is why your effective rate is always below your top marginal rate.
