Understanding Tax Brackets
Marginal vs Effective Rate: Your marginal rate is what you pay on your last dollar earned. Your effective rate is your total tax divided by total income—always lower than marginal.
Progressive taxation: The US uses a progressive system. Higher income is taxed at higher rates, but only the portion in each bracket pays that rate.
Common misconception: Moving to a higher bracket doesn't mean ALL your income is taxed at that rate—only the amount above the threshold.
2024 rates: Federal brackets range from 10% to 37%. State taxes vary widely.
