I just received the same call from this phone number stating that the IRS was filing a law suite against me. I too have not problems with the IRS. It made me very anxious until I looked up the phone number on this site.
This operation is based overseas and that makes it impossible for our agencies to conduct an investigation.
In all the years I have been registered with the DNCR, I have yet to receive a call from a legitimate company that I have never done business with. So it works for me.
5-1-15. Received call from this number. Answering machine picked up. Did not leave message. Any number I don't know I let the answering machine take the call.
IRS says this scam has costs more than $15 million in 2014 and that's just the known victims. Others may not have reported the loss because of embarrassment. Please report the call here:
