My employer has recently issued supplemental insurance premiums to the full time staff members (2) but in exchange their income is reduced. We have an outside payroll company that does our payroll and they send the payroll register to us which I (the bookkeeper) enter into our Quickbooks. The payroll company is receiving the bill from the insurance company for their records which they just notate but we are actually paying the bill. 

The question is: since we are not receiving income for this expense and it needs to wash out in our payroll expenses, how do I reflect this in QB? When paying the vendor do I enter it under a employer payroll expense and then do a general journal entry from payroll gross.  I am told that this is essentially a pass through expense and I do this for another expense account.
