Worked Examples

Example 1: Single Filer with $50,000 Income

For a single filer with $50,000 income:

  • Taxable Income = $50,000 - $14,600 (standard deduction) = $35,400
  • Tax Calculation:
    • $11,600 × 10% = $1,160
    • ($47,150 - $11,600) × 12% = $4,411.20
    • ($35,400 - $47,150) × 22% = $1,846.80
    • Total Tax = $1,160 + $4,411.20 + $1,846.80 = $7,418
  • Effective Tax Rate = ($7,418 / $35,400) × 100 ≈ 21.0%

Example 2: Married Filing Jointly with $100,000 Income

For a married couple filing jointly with $100,000 income:

  • Taxable Income = $100,000 - $29,200 (standard deduction) = $70,800
  • Tax Calculation:
    • $23,200 × 10% = $2,320
    • ($94,300 - $23,200) × 12% = $8,544.80
    • ($70,800 - $94,300) × 22% = $4,544.80
    • Total Tax = $2,320 + $8,544.80 + $4,544.80 = $15,409.60
  • Effective Tax Rate = ($15,409.60 / $70,800) × 100 ≈ 21.8%
