Worked Example

Let's say an employee has a gross income of $50,000 per year, is single, and has no dependents.

  • Social Security Tax: $50,000 x 0.062 = $3,100
  • Medicare Tax: $50,000 x 0.0145 = $725
  • Federal Income Tax: using the federal income tax tables, let's say the tax amount is $8,000
  • State Income Tax: using the state income tax tables, let's say the tax amount is $2,000
  • Unemployment Tax: $50,000 x 0.006 = $300 Total Payroll Tax: $3,100 + $725 + $8,000 + $2,000 + $300 = $14,125
