Educational income tax estimator for 10 major countries with year selection (current + two prior). Transparent bracket breakdowns and notebook export.
Tax calculator (educational)
The Tax Calculator is a multi-country income tax estimator designed for learning and scenario comparisons. Select a country and tax year, enter income, and inspect a bracket-by-bracket breakdown. The focus is on understanding marginal brackets, effective rate, and “what changes if income changes?” intuition.

- Notebook — capture assumptions (year, profile, deductions) and keep scenarios reproducible
How to interpret the outputs
- Taxable income: the income amount the estimator applies brackets to (after modeled deductions/allowances).
- Total estimated tax: sum of bracket-level tax amounts (simplified).
- Effective rate: total tax ÷ gross income (a blended rate).
- Marginal rate: the rate on the next dollar of taxable income (top bracket reached).
Helpful explainers: tax brackets explained and marginal vs effective tax rate.
Important disclaimer
Educational use only. Real tax liabilities depend on residency, deductions, credits, local taxes, payroll taxes, and legal definitions that vary by jurisdiction and year. This model is simplified and may omit important rules. Always verify with official sources and/or a qualified professional.
Verification checklist
- Confirm the year and profile (filing status) match your scenario.
- Check whether the tool uses gross or taxable income for your country/profile and whether a standard deduction/allowance is modeled.
- Compare against an official source for the same assumptions (and note any differences in credits/local taxes).
- Use deltas: try increasing income slightly and confirm that tax increases by about the marginal rate in that range.
