California Reject Code S0000-080:
This reject occurs if the EFIN has been entered incorrectly in the program or the Electronic Return Originator (ERO) is not registered to electronically file tax returns with the IRS.
In order to be enrolled in the California e-file Program, the ERO needs to be an accepted participant in the IRS e-file program. California receives confirmation within 7-10 business days after the IRS accepts the ERO into their program.
If you're an ERO and you've received your EFIN from the IRS, liaise with the California FTB for assistance. See here for more information.
