I got a voicemail from an unknown number. It was a robocall stating that I am being sued by the IRS and to call 202-657-6406. Definitely a scam call. I am somewhat familiar with IRS procedures and they don't just file suit without reason. I don't owe them any back taxes and even if I did I would have received several certified letters from them before they file suit. But even before they file suit they would attempt to garnish my wages. Calls like this out of the blue are definite scams. They will either try to convince you that they are the IRS or the number will actually end up being forwarded from this Washingto, DC number to an overseas number and charge you out the wazoo on your phone bill.
