A friend's parents went to this lady to have their return prepared. They said she added on mortgage interest (they don't have a mortgage), unreimbursed employee expenses & medical expenses. The only thing they actually had was some medical expenses due to a surgery done on the wife. I had also been hearing from several other people about how it was possible for their friends to be getting such large refunds when they were working at the same place and pretty close to same salaries, etc..
A friend has 2 brothers working at the local IRS office, one I believe is a revenue agent the other is an investigator. I just gave them a heads up. I'm not sure if they acted on my tip or maybe had other info. The manager of the local HRB also mentioned this lady a couple of times. She had also been hearing stories coming from that place.
