The IRS notes: "If it sounds too good to be true, it probably is!" Don't become a victim to any scheme that offers instant wealth or exemption from your obligation as a United States citizen to file tax returns and/or pay taxes. Some of these schemes can literally cost you your life savings. Others can result in your prosecution and imprisonment if you knowingly participate in them.
