Called at 11:18 a.m. DST and left message:  "Hello, this call is officially your final notice from IRS, Internal Revenue Service.  The reason of this call is to inform you that IRS has filed a lawsuit against you.  To get more information about this case file, please call immediately on our department number, 2089737888.  Thank you."

Exact same call this morning.  same #.  Called back ,told them I know it's a scam and reported to proper authorities.  They hung up.

Received a call from 1-206-973-7888.  Caller ID was 'Seattle WA'.  Checked 800 Notes and blocked.  A quick pick up and hang up and then I block them after checking 800 Notes.

Automated message saying this was a final warning from the IRS claiming I had not paid taxes and were filing a lawsuit.  Caller ID said it was from Seattle. Female voice. Don't fall for it!

I recieved a call claiming that the IRS was about to file a lawsuit against me and that the call was my final notice.  Since my address is current with the IRS and I received nothing in the mail, I suspected this was a scam.  When I called back they hung up on me when I started questioning them.  I reported the phone number to the IRS.  Don't know if it will do any good.
