I understand how important it is to accurately calculate your worker's compensation each reporting period, @626848609. 

Since the option to use Experience Modification which creates rates assigned by insurance companies to calculate Workers' Compensation premiums isn't available in QuickBooks Online Payroll, I recommend sending feedback directly to our Product Developers. By sharing your valuable insights and suggestions, you can contribute to the continuous improvement of our software. They will carefully review your feedback, identify areas that require enhancements, and consider incorporating them into future updates. Here's how:

1. Open your QuickBooks account.
2. Hit the Gear icon at the top, then select Feedback.
3. Type in your product suggestions.
4. Click Next to submit feedback.

You can keep track of the status of your request by visiting our Customer Feedback page.
