How the Calculation Works
U.S. federal income tax uses a progressive bracket system (2024 rates):
Single Filers:
• 10% on income up to $11,600
• 12% on income $11,601-$47,150
• 22% on income $47,151-$100,525
• 24% on income $100,526-$191,950
• 32% on income $191,951-$243,725
• 35% on income $243,726-$609,350
• 37% on income over $609,350
Calculation Process:
- Start with gross income
- Subtract standard/itemized deduction = Taxable income
- Apply progressive tax brackets to taxable income
- Sum tax from each bracket = Total tax owed
Example: Single filer, $75,000 income, standard deduction:
• Taxable income: $75,000 - $14,600 = $60,400
• Tax: ($11,600 × 10%) + ($35,550 × 12%) + ($13,250 × 22%)
• Tax: $1,160 + $4,266 + $2,915 = $8,341
• Effective rate: 11.1% (not 22% marginal rate)
