Worked Examples

Example 1: Single Filer with $50,000 Gross Income

Using the standard deduction of $13,850:

  1. Taxable Income = $50,000 - $13,850 = $36,150
  2. First $11,000 taxed at 10% = $1,100
  3. Next $33,725 taxed at 12% = $4,047
  4. Remaining $1,425 taxed at 22% = $314
  5. Total Federal Income Tax = $1,100 + $4,047 + $314 = $5,461

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

Using the standard deduction of $27,700:

  1. Taxable Income = $100,000 - $27,700 = $72,300
  2. First $22,000 taxed at 10% = $2,200
  3. Next $67,450 taxed at 12% = $8,094
  4. Remaining $1,950 taxed at 22% = $429
  5. Total Federal Income Tax = $2,200 + $8,094 + $429 = $10,723
