Can additional pay types (over and above base pay) be set up as a percentage as opposed to set amount?

Hello ron-inzaneinteri,

Welcome to Community!  I can understand the benefit of being able to add additional pay types as a percentage.  However, this option currently isn't available in QuickBooks Online Payroll.

If you would like to see this in future updates, please don't hesitate to submit a suggestion to our Development Team by going to your Settings ⚙, then select Feedback. Customer recommendations are greatly appreciated, in assisting us with improving your overall customer experience in QuickBooks Online.

Feel free to reach back out with other questions.  We would be glad to help!
