I also just received the call that the IRS is suing me and to call them back. I received other calls like this from other numbers, I wish they would stop!
Recieved 2 calls from this number yesterday with an automated voice/message stating that the IRS has filed a law suit against me and to call the number back for more information
IRS SCAM
Bizarre call from this TX number. Man with heavy accent (sounded Indian) claimed he was a "federal agent" and that the IRS was suing me. Didn't try to get money during this call, but he knew my address and name which is very concerning. He said notices had been sent (they have not) and that I could go to jail, etc. Here is a relevant link with recent info and how to report these scam numbers: http://kxan.com/2016/02/25/what-to-do-if-you-get-a-scam-irs-call/ I reported it.
