How US Income Tax Works

1

Progressive Brackets

The US uses a progressive tax system where higher income is taxed at higher rates.

2

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).

3

Marginal vs Effective Rate

Your marginal rate is the highest bracket you reach; your effective rate is total tax divided by income.

Important Notes:

  • 2025 tax brackets: This calculator uses 2025 federal tax brackets and standard deduction amounts.
  • State taxes vary: Some states have no income tax (TX, FL, WA), while others range from 1% to 13.3%.
  • This is an estimate: Actual tax liability depends on credits, additional deductions, and other income sources.
  • Not tax advice: Consult a tax professional for personalized guidance.
