Thank you for joining the thread to notify us of your experience, Misty. I'll share some solutions to get the correct calculations of your Payroll Summary by Class report.

As per our Community Champion above, the main factor with this behavior is when the Job Costing, Class, and Item tracking for paycheck expenses feature is disabled. You can review your payroll preferences by following these steps to isolate the issue:

1. Go to the Edit menu, then click on Preferences.
2. Click on Payroll & Employees, then go to the Company Preferences section.
3. Set your preferences and mark the box beside Job Costing, Class, and Item tracking for paycheck expenses.
4. Hit Done to save the changes.

If the feature was disabled, the system never split up your items and taxes by class. To fix this, you can modify the existing or affected transactions to use the new preference when classifying classes to your payroll entries.
