How is income tax calculated?

Income tax is calculated by applying progressive tax brackets to your taxable income (gross income minus deductions and exemptions). Each bracket has its own rate applied only to the income within that range.

What is the difference between effective tax rate and marginal tax rate?

The marginal rate is the rate applied to your last dollar of income (your highest bracket). The effective rate is total tax divided by gross income — your actual average rate, which is always lower than the marginal rate.

Which countries have the highest income tax rates?

Among the countries supported, France, Germany, and the Netherlands typically have the highest top marginal rates (45–55%), while the UAE, Qatar, and Saudi Arabia have zero income tax.
