The US uses a progressive tax system with marginal tax brackets. This means only the income within each bracket is taxed at that rate, not your entire income. For 2024, there are seven federal tax brackets ranging from 10% to 37%. Your 'marginal rate' is the highest bracket your income reaches, while your 'effective rate' is your actual average tax rate.
Tax Calculation
Tax = Σ (Income in Bracket × Bracket Rate)Your marginal rate is the highest bracket your income reaches (e.g., 22%). Your effective rate is your actual average rate after applying all brackets (typically much lower). For example, someone in the 22% bracket might have an effective rate of only 12%.
