EDUCATION
Understanding Federal Tax Brackets
The U.S. federal income tax system uses a progressive structure with seven tax brackets. As your income rises, only the income within each bracket is taxed at that bracket's rate. This means moving into a higher bracket does not cause all of your income to be taxed at the higher rate.
Your marginal tax rate is the rate applied to your last dollar of income. Your effective tax rate is the average rate across all your income. The effective rate is always lower than or equal to the marginal rate because lower portions of your income are taxed at lower rates.
