The woman on the phone couldn't tell me for sure but she looked at my filing history and said there were 14 rejected returns filed for my EFIN this year and I usually have none so they assumed it was compromised. I did have two rejected returns earlier this season for clients whose identity was compromised so there were already returns filed for their SS#s but no way have I had 14 rejections before yesterday so I guess maybe it was compromised. (of course I've probably had 14 rejections just in the past 24 hours since they deactivated my EFIN. Hopefully they don't deactivate it again!)
