Tax evasion is a criminal offense under federal and state statutes. A person who is convicted is subject to a prison sentence, a fine, or both. The failure to file a federal tax return is a misdemeanor, but a consistent pattern of failure to file for several years will constitute evidence that these failures were part of a scheme to avoid the payment of taxes. If this pattern is established, the violator may be charged with a felony under section 7201 of the Internal Revenue Code.
