I just received a call on my answering machine claiming to be from the IRS and threatening legal action. Asking me to call them at 818-745-2026 so they can "help me". Out of curiosity I called and the person who picked up had an Indian accent (like the one who left the message). He claimed I owed the IRS money. I told him I didn't believe him at which point he threatened criminal action. I hung up and reported it to the IRS.
Just wanted to warn other people. The IRS would not contact you this way.
