Your name in the HR / Payroll system must reflect the name you have with the Social Security Administration. When you change your name with SSA we can update your name.
Go to ME and Personal Information
Go to Personal Details
Use the Pencil to Edit the Name
Enter the Date, the change and upload a scan of the new SS card or letter from the SSA saying that the name has been changed with the SSA.
Hit submit and it will show the changes are submitted for approval.
HR Records will approve the change and update the government I9 to reflect the new name.
