In the Payroll Federal and State Taxes screen under Payroll Setup click Select Federal or State Tax and then select PASUTA to being setting it up as a new tax code which you can then add at the employee level. 

Thank you for the reply back.  I have this setup and it's coming out for the employer portion.  How do I add the employee portion?

This is an out of the box tax so we can't really see what is happening in the background. Sage researches these taxes very well. It may be that you have not reached some sort of minimum threshold. If you feel an out of the box tax is not calculating correctly I recommend starting a chat session with Sage, which you can do by opening the question mark/help menu in the upper right of HRMS and selecting Sage Live Chat.

Thank you for your help and I ended up doing a Sage Live Chat and found out that I need to manually setup a new tax code under the "Local/Other Tax" codes.
