The US uses a progressive tax system. Each bracket only applies to income within that range. For example, at $50,000 single filer, the first $11,600 is taxed at 10%, the next portion up to $47,150 at 12%, and the remainder at 22%.
The standard deduction reduces your taxable income before tax brackets are applied. For 2024: Single $14,600, Married Filing Jointly $29,200, Head of Household $21,900. Filers age 65 or older receive an additional deduction.
Your marginal rate is the rate on your last dollar of income (the highest bracket you reach). Your effective rate is your total tax divided by total income, always lower than your marginal rate due to lower-bracket amounts.
