If you choose to debit every thing of Payroll Expense, why not just do one, instead of two debit? However, if you put everything into Payroll Expense account, it will be more complicated when you have to reconcile or you want to run report each types of payroll expenses. it is clearer to create different payroll expenses like wages, fringes, federal taxes, state taxes, worker's compensation...
Hope it helps
All the best
