The US federal income tax uses a progressive (marginal) system. Each portion of your taxable income is taxed at the rate of the bracket it falls into. Your effective tax rate is the average rate across all brackets, while your marginal tax rate is the rate applied to your last dollar of income. This means earning more money only increases the tax rate on income above your current bracket threshold — not on all of your income.
