When they call, if you want to fluck with them, ask them, "You're from the IRS, huh? Okay here's some validation questions. First, who is your boss, the IRS Commissioner (Answer: John Koskinin), and who is the overall boss, the Secretary of the Treasury (Answer: Jack Lew). You MUST know your bosses if you're for real".

Bet a gabillion bucks, they stammer and hang up! :-)

Bogus IRS Scam.  File a complaint with the FCC, if they get enough complaints, they will act on it.  The Do-Not-Call list is worthless.  Complaining on here accomplishes nothing, you have to take action!

These horrible people are calling and saying they are the IRS.

I received a message this past Friday, November 6th at 3:44 pm from a robo call claiming to be the IRS. The call was made to my home phone number.

The message was as follows, "This call is officially a final notice from the IRS, Internal Revenue Services. The reason for this call is to inform you the IRS is filing lawsuit against you. To get more information about this case file, please call immediately at 346-971-6231".

I realize this is a total scam as the IRS would never leave such a message over the phone but wanted to document my experience online for others to see. I've filed complaints with both the FCC and my state's Attorney General's office.
