Welcome back to the QuickBooks Community, usercheryle. The platforms for QuickBooks Online and QuickBooks Desktop are distinct. There are several features and functions that work differently and are meant to work independently. With this, I'll be sharing details on how workers’ compensation works in QBO and ensure you can send feedback so the option you want to perform will make it possible.

Once your workers' compensation policy is activated, your payroll data is used to calculate your exact premium each time you run payroll. However, as previously stated, it is not possible to split your employees' paychecks between classes or assign multiple classes to a single employee. A list of classes under Worker's Comp is also currently unavailable.

As a workaround, you can follow the steps shared by my colleagues to create another pay type or set up your accounting preferences to track payroll expenses by class.

For now, I suggest going to the Gear icon in QuickBooks Online and choosing Feedback. This way, you can submit a request about having the option to add the feature that you need. Any recommendations are sent to our engineers for consideration in future updates.

Lastly, you may refer to this article on how you can run different payroll reports that you can use to view useful information about your employees: Run payroll reports in QuickBooks Online Payroll.

I'll be around to help if you have any other questions about managing classes in QBO. Just let me know by leaving a comment below, usercheryle. Have a nice day ahead.
