Beware of scams regarding the Internal Revenue Service. The Internal Revenue Services does not call you and tell you that you to pay them money today or you will go to jail. They also do not call and tell you that you are a thief and that if you don’t pay today, again you will go to jail. They also don’t send you an email which supposedly contains a voicemail message for you. Of course, I don’t know what is says, as I didn’t open it. Generally the IRS will communicate with you via U.S. Mail.
