What version of Sage 100 are you using including the product update? Have you done the upate to the eFiling (Aatrix)? Do you see the SDI tax in the Employee Maintenance, Tax Summary, CA field Employee SDI for Year to Date? Is it possible the earnings code you used was not subject to SDI? Or that pension or cafeteria codes reduced it to 0.00? If it is not showing for any employees, it also could be the way Tax Table Maintenance for CA was setup. I just tested on Sage 100 2017 no product update and mine went over to the efiling grid perfect.

We updated the Aatrix software and now it is picking up the CA SDI. Thanks.
