Note: 1
FICA Social security’s tax
FICA - social security tax is payable on maximum wages of $128,400.
Once an employee's year to date earnings or cumulative earnings exceed the wage base of $128,400, no additional Social Security tax isto be withheld from the employee's earnings.
So, before calculating the FICA - social security tax, we have to check whether the September earnings along with cumulative earnings until August is exceeding $128,400 or not .
If September earnings plus cumulative earnings until August is exceeding $ 128,400, then.
Social Security tax = [($128,400 minus Cumulative earnings until August) or gross salary whichever is lesser] into 6.20%. and if it is not, then
Social Security tax = Gross pay during September into 6.20%
