Worked Example

Let's calculate the federal income tax for a single filer with $50,000 income:

Total Income: $50,000
Standard Deduction: $13,850
Taxable Income: $50,000 - $13,850 = $36,150
Tax Calculation:
- $11,000 × 10% = $1,100
- ($36,150 - $11,000) × 12% = $2,898
- Total Tax = $1,100 + $2,898 = $3,998

This example shows that a single filer with $50,000 income would owe approximately $3,998 in federal income tax.
