Yeah, it is a scam. I owed the IRS a couple of thousand last year, but paid it to them, and I have a nice receipt saying that I am clear with them and my balance is $0.00. So I get a message yesterday on the answering machine that says "... is filing a lawsuit against you. In order to discuss your case, please call 360-355-8677. The fact that there is no name mentioned, only that someone is filing a lawsuit against you. So I looked the number up on here and it mentions that it is an IRS scam. So I do decide to call them and tell them that they are POS and am not worried about a lawsuit from them as I have receipt from the real IRS. Don't you know it, but when I call, I get a "Your call cannot be completed as dialed. Please check the listing and dial again." At other times, it rings the fast busy signal. Ha Ha, they can't even screw that up right.
