Worked Example

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

Total Income: $50,000
Standard Deduction: $6,300
Taxable Income: $50,000 - $6,300 = $43,700
Tax Calculation:
- $9,075 × 10% = $907.50
- ($36,900 - $9,075) × 15% = $3,821.25
- ($43,700 - $36,900) × 25% = $1,675
Total Federal Income Tax: $907.50 + $3,821.25 + $1,675 = $6,403.75

This single filer would owe approximately $6,403.75 in federal income tax for 2015.
