All the checklists and workflow documents I have read indicate that the Payroll tax update needs to be done before processing the first payroll of 2021 and the year end update (version 20.3) can be done either before or after the last payroll of the year, but must be done before running W2 or 1099 forms for 2020.

Today, I downloaded the Payroll Tax 2021 Release Notes for the United States and on page 1 there is a note that says :  "In order to use the payroll tax updates for 2021, you should be using Sage 300 CRE version 20.3 or later."

I need to process and post TWO 2021 payrolls on version 20.1 BEFORE a scheduled upgrade to 20.3.  My question is CAN we run the payroll tax update on version 20.1?
