Worked Example

Let's calculate the federal income tax for a single filer with $50,000 total income in 2017.

1. Standard deduction for single filer: $6,350
2. Taxable income: $50,000 - $6,350 = $43,650
3. Tax calculation:
   • $9,325 × 10% = $932.50
   • ($37,950 - $9,325) × 15% = $4,353.75
   • ($43,650 - $37,950) × 25% = $1,432.50
4. Total federal income tax: $932.50 + $4,353.75 + $1,432.50 = $6,718.25
