Answer:
Social Security Amount = $7,960.8
Medicare Amount = $9,378.6
Additional amount (FICA taxes) to contribute = $17,339.4
Explanation:
Given:
Base salary = $646,800.
Required to withhold = 6.2% Social Security tax
Medicare tax = 1.45%
FICA base amount = $128,400.
Computation:
Social Security Amount = (FICA base amount) × Social Security tax
Social Security Amount = $128,400 × 6.2%
Social Security Amount = $7,960.8
Medicare Amount = Base salary × Medicare tax
Medicare Amount = $646,800 × 1.45%
Medicare Amount = $9,378.6
Additional amount (FICA taxes) to contribute = $7,960.8 + $9,378.6
Additional amount (FICA taxes) to contribute = $17,339.4
