Received bogus call and message stating IRS plans to sue me and to call this number immediately.  Right. This is obvious spam or a phishing attempt.

I just received the same call.

Fake automated message claiming to be from the IRS and stating that it is a final warning of a lawsuit being filed by the IRS.

Call came from the above phone number. When I called this number they identified themselves as the IRS. I am a CPA-auditor and investigator and found a problem with the call ( generally all comes in writing when the IRS has an important issue to resolve). When my tone was firm they hang up right away and did not take any further call. These people had an Asian Indian accent. This is a fraud as I see it but reporting it to the IRS takes a long waiting line.

I just received a call from this number saying they are the IRS and they did an audit on my taxes from 2008 - 2013 and I owe $4000. They said if i did not pay today I would be arrested since their was an arrest warrant for me. This was a red flag since no one contacted me prior to this and the person refused to provide documentation prior to payment. He wanted me to leave work that moment and take out money from my bank account to wire it to him (another red flag). I asked him to hold on and googled the phone number and seen tons of reviews saying the number was fake. After confronting him he said to be prepared to get asserted and hung up. The guy has a very heavy accent.
