learn.whatIsHeading

A tax estimator projects your estimated annual income tax liability based on income, filing status, deductions, and credits. It helps avoid underpayment penalties and plan quarterly estimated tax payments.

分步指南

  1. 1Calculate Adjusted Gross Income (AGI): gross income minus above-the-line deductions
  2. 2Subtract standard deduction (2024: $14,600 single, $29,200 married)
  3. 3Apply progressive tax brackets to taxable income
  4. 4Subtract tax credits (dollar-for-dollar reduction, more powerful than deductions)

例题解析

输入
Single filer · $75,000 income · standard deduction 2024
结果
Federal tax ≈ $10,294 · Effective rate ≈ 13.7%
