Final answer:
The income tax withheld per year from the marketing executive's annual salary after her 401(k) contribution is $19,386.
Step-by-step explanation:
To determine the amount of income tax withheld from a marketing executive's annual salary, we first need to find her taxable income. Since she contributes $6,500 to her 401(k) plan, this amount is deducted from her gross salary before taxes. Therefore, her taxable income would be:
Gross Salary - 401(k) contribution = Taxable Income
$78,300 - $6,500 = $71,800
Now, we calculate the income tax by applying the 27% tax rate to her taxable income:
Taxable Income x Tax rate = Income tax withheld
$71,800 x 0.27 = $19,386
The amount of income tax withheld per year from the marketing executive's salary is $19,386.
