How US Federal Tax Brackets Work
The US federal income tax system is progressive, meaning higher income is taxed at higher rates. However, a common misconception is that earning more pushes all your income into a higher bracket. In reality, only the income within each bracket is taxed at that rate.
This calculator shows you exactly how much tax you owe in each bracket, your effective tax rate, and your estimated take-home pay after federal taxes and FICA contributions.
