计算示例
$80,000 income, 5% state rate, $5,000 state deduction, 15% federal effective rate.
- State taxable = $80,000 - $5,000 = $75,000
- State tax = $75,000 x 5% = $3,750
- Federal tax = $80,000 x 15% = $12,000
- Combined = $3,750 + $12,000 = $15,750
- Combined rate = $15,750 / $80,000 = 19.7%
- Take-home = $80,000 - $15,750 = $64,250
