Answer: The social security tax will be withheld through September.
Explanation:
Social Security maximum base amount = $128,400
social security tax rate = 6.2% = 0.062
Medicare tax = 1.45% = 0.0145
Medicare Tax = no maximum
Base salary = $180,000
Social security tax amount = 0.062 × $128,400 = $7,960.80
Medicare Tax = 0.0145 × $180,000 = $2,610
Social security tax to be withheld = $7,960.80
Social security maximum base amount = $128,400
Monthly salary = $15,000
$128,400 ÷ $15,000 = 8.56
($15,000 × 8) + ($15000×0.56) = $120,000 + $8400
Therefore, the social security tax will be withheld through the ninth month which is between January to September
