I had a message on my recorder that I was to call this number immediately and it said that they were the criminal investigation department of the IRS and I'm being sued by the IRS to call immediately.

I got a call today saying the same thing, That the Irs is filing a criminal case against me. But I don't owe the Irs and when I try to call the number back it goes to a voicemail..

•You can also file a complaint with the Federal Trade Commission at FTC.gov. Add "IRS Telephone Scam" to the comments in your complaint.

Do consider maybe getting a call blocking device or phone.. You can google them and many are around $50.00 or so.If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If you have a smart phone, there is a free app called call control. Iphones appear to have apps also. Another one is called Mr. Number.

I had the same last night saying the same msg. When I looked the number it is in Washington state.

Recorded call saying the IRS is pursuing a criminal case against me for back taxes.
