Say you have employees that make a total of $20000 in a period, the withholding is $1500 and the payroll tax is .0765 ,
they'll ask you how much money needs to be in the payroll account. Well all that you need to do is multiply the $20000 times 1.0765, to get $21530. The withholding is just that, the withholding of the EMPLOYEE's portion, it's already coming out of their portion..
So all you need to add to the payroll account, is the employer's portion.
The employees withholding will usually be given, $1500, then you also withhold their portion of fica medicare .0765, or whatever the given rate is.
The employer pays only fica medicare. That's the only “extra” portion that you add.
