How US Income Tax Works
Progressive Brackets
The US uses a progressive tax system where higher income is taxed at higher rates.
Standard Deduction
Your income up to the standard deduction amount is not taxed (${DEDUCTIONS_BY_YEAR[input.year]?.single ?? 15000} single, ${DEDUCTIONS_BY_YEAR[input.year]?.married ?? 30000} married in 2025).
Marginal vs Effective Rate
Your marginal rate is the highest bracket you reach; your effective rate is total tax divided by income.
