When you set up or edit a payroll item, you need to select the Track
Expenses By Job checkbox to allow addition or company contribution
class information. If the checkbox is cleared, the payroll item will show as
unclassified on the report.
Go to the Lists menu and click Payroll Item List.
Double-click the affected payroll item to open the Edit Payroll Item window.
Select the Track Expenses By Job checkbox to ensure future checks are
allocated by class.
Important: Selecting the checkbox won't correct paychecks that
have already been issued.)
What if the checkbox isn't there?
The payroll preference "Report all payroll taxes by Customer:Job,
Service Item and Class", must be turned on for the Track Expenses By
Job checkbox to be visible when you're editing payroll items.
Go to the Edit menu and click Preferences.
In the Preferences window, click Payroll & Employees in the list on the left.
Click the Company Preferences tab.
Select the "Report all payroll taxes by Customer:Job, Service Item and Class" checkbox.
