Answer: $3,266.55
Explanation: The employee's salary scale falls between $1 and $128,400 so the FICA tax rate for social security of 6.2% and Medicare of 1.45% applies to him.
Social security tax payable
$42,700 x 6.2% / 100 = $2,647.4
Medicare tax payable
$42,700 x 1.45% / 100 = $619.15
Total tax payable by the employee
$2647.4 + $619.15 = $3,266.55
