Answer 1

Answer:

The answer is: Marc´s effective tax rate is 18.29% equivalent to $18,289.50

Explanation:

Marc is a single filer, so his taxable income of $100,000 falls under the fourth tax bracket ($82,501 to $157,500) with a tax rate of 24%. To calculate Marc´s effective tax rate:

Taxes due = $14,089.50 + [24% x ($100,000 - $82,500)]

                  = $14,089.50 + (24% x $17,500)

                  = $14,089.50 + $4,200

                  = $18,289.50

So Marc´s effective tax rate (ETR) = ($18,289.50 / $100,000) x 100 = 18.29%

Note: The $10,000 Marc earned in interest from municipal bonds (City of Birmingham bonds) are tax exempt, so they are not included in these calculations.
