First part cut off.  The second part is to have me or attorney call back or the "legal situation falls on you".  This was to my company cell phone.  Also got a phone call this morning with a similar voicemail from 804-335-1531.  Voice was heavily accented.

I just got a call exactly like yours. I'm not calling back. Yep. A heavily accented voice.

Received message stating legal tax actions taken against me. Called back person stated I have been committing tax crimes the past 5 years and a warrant has been issued for my arrest

That is exactly what happened to me today. They told me that a sheriff would be at my door two hours from the call.

I had this same call.  The person recited some legal codes saying I have a warrant for my arrest due to tax fraud.  I asked him why I did not receive anything from the IRS and he stated the audit was done last week and there is now a warrant for my arrest and the local sherriff will be coming to take me in to custody.  I asked more questions as to why i was not notified by IRS and he stated to get a lawywer and hung up on me.
