How the income tax calculator works
Your income is first reduced by the 2026 standard deduction for your filing status to get taxable income. The progressive brackets then apply: each slice of income is taxed at its own rate, so your effective rate is lower than your top (marginal) rate.
2026 standard deduction: $16,100 single · $32,200 married filing jointly · $24,150 head of household
