You may need to set up a different pay category if you wanted to assign wages expense to a different account. Once you've added a Pay Category in Payroll Settings, you can assign it to your preferred expense account. Here's how:
Go to Employees tab and select Payroll Settings.
Select Chart of Accounts.
Select Pay Categories.
On the pay category created, select Not specified.
Select an Expense Account you would like to allocate it to.
