Income Tax Calculator
Estimate your income tax liability
How It Works
Most countries use a progressive tax system — the more you earn, the higher the rate applied to each additional dollar of income.
Effective Rate = Total Tax ÷ Gross Income × 100
After-tax Income = Gross Income − Total Tax
US brackets shown are for 2024 Single filer status. Other countries use simplified progressive estimates.
FAQ
What is a marginal tax rate?
Your marginal tax rate is the rate applied to the last dollar you earn — i.e., the top bracket you fall into. It differs from your effective rate, which averages across all income levels.
Does this calculator include state or local taxes?
No. This tool estimates national/federal income tax only. State, provincial, or local taxes vary widely and are not included. In the US, state income taxes can add 0–13% depending on where you live.
