EFW2 format trial files
We recommend that you run EFW2 Reporting and review the file to identify any potential problems before running a final file to submit.
Because EFW2 Reporting is not an update program, you can run it multiple times. For example, you can run it after you close out the payroll year and after your first payroll cycle of the new year.
If there are any errors in your W-2 data, the HR Payroll creates an error report. Review the error report and correct any errors before you submit the file.
