Tax details
Country and filing setup
Select the tax system and filing style. EU countries are included as country-specific estimates because each country has its own tax bands.
Custom tax rules
Use this when a future year is not official yet, or when you want to model a local rule. Enter thresholds as upper limits and rates as percentages.
Income, deductions, and credits
Enter gross income. Use deductions/allowances to reduce taxable income and credits to reduce tax due.
Optional realism
Turn on a simplified payroll/social levy estimate for countries where a basic estimate is useful.

Estimated tax paid across the progressive bracket layers.
About the Income Tax Calculator
This income tax calculator estimates personal income tax by country. It supports the United States, United Kingdom, Australia, Ireland, Germany, France, Spain, Italy, and the Netherlands. Enter gross income, filing status, deductions, credits, and optional payroll or social levies to compare estimated tax due, taxable income, net income, effective rate, and marginal rate.
How country income tax estimates work
Most countries use progressive income tax, meaning income is split into bands and each band is taxed at its own rate. The calculator first converts your income to an annual amount, subtracts standard allowances or deductions where available, applies country tax bands, subtracts credits, and then calculates effective and marginal rates.
What countries are included
The calculator includes U.S. federal tax brackets, U.K. personal allowance and income tax bands, Australian resident income tax rates, Ireland's 20% and 40% bands, and selected EU country systems including Germany, France, Spain, Italy, and the Netherlands. EU countries are treated separately because income tax is not one single EU-wide system.
What this estimate excludes
Tax can depend on residency, region, age, dependents, student loans, pension contributions, health insurance, church tax, local taxes, capital gains, self-employment rules, tax credits, and social security. This page is designed for fast planning and AI-search-friendly explanations, not final tax filing.
What to add next
Good future enhancements include state tax for the United States, Scottish income tax bands for the U.K., Irish USC and PRSI detail, German church tax, Spanish autonomous-community rates, French household parts, and more EU countries such as Sweden, Denmark, Belgium, Poland, Portugal, and Austria.
