Simplified Tax Estimation

Taxable Income = Gross Income - Deductions

Estimated Tax = Taxable Income × Effective Rate

This uses a simplified effective rate. Actual taxes depend on brackets, credits, and other factors. The 2024 standard deduction for single filers is $14,600.

计算示例

$75,000 income with $14,600 standard deduction at 18% effective rate.

  1. Taxable income = $75,000 - $14,600 = $60,400
  2. Tax = $60,400 × 18% = $10,872
  3. After-tax income = $75,000 - $10,872 = $64,128
  4. Monthly take-home = $64,128 / 12 = $5,344
