15-1-216 . Uniform penalty and interest assessments for violation of tax provisions -- applicability -- exceptions -- uniform provision for interest on overpayments. (1) A person who fails to file a required tax return or other report with the department by the due date of the return or report, including any extension of time allowed for in Title 15, chapter 30 or 31, must be assessed a late filing penalty. The penalty is the greater of $50 or 5% of the tax due for each month during which there is a failure to file the return or report, not to exceed an amount up to 25% of the tax due. The late filing penalty is calculated from the due date or extended due date until the department actually receives the late return or report. The penalty is computed only on the net amount of tax due, if any, as of the original due date or extended due date provided for in Title 15, chapter 30 or 31, after credit has been given for amounts paid through withholding, estimated tax payments, or other credits claimed on the return.

(ii) A penalty imposed under subsection (2)(a)(i) may be waived if:
(A) the taxpayer pays the tax and interest due with the tax return or report within 30 days following the first notice from the department to the taxpayer of the amount due; or

The penalty may not exceed 15% of the tax due.
(ii) A penalty imposed under subsection (2)(b)(i) may be waived if the taxpayer pays the tax and interest due with the tax return or report within 30 days following the first notice from the department to the taxpayer of the amount due.
(c) The penalty imposed under subsection (2)(a) or (2)(b) accrues daily on the unpaid tax from the original due date of the return regardless of whether the taxpayer has received an extension of time for filing a return.

(3) (a) Subject to subsection (3)(b), a person who makes a substantial understatement of tax imposed under Title 15, Title 16, chapter 11, or Title 53, chapter 19, part 3, must be assessed a substantial understatement penalty in an amount equal to 20% of the understatement. As used in this subsection (3), "understatement" means the amount of the tax required to be shown on the return for the tax year less the amount of tax that the taxpayer reported on the return. For purposes of this subsection (3):
(i) there is a substantial understatement of tax penalty imposed under Title 15, chapter 30, except for Title 15, chapter 30, part 33, if the understatement exceeds the greater of 10% of the amount of tax required to be shown on the return or $3,000; and

(A) 10% of the amount of tax required to be shown on the return if the understatement is greater than $10,000; or
(B) $500,000.
(b) The amount of substantial understatement of tax penalty must be reduced by the amount of the understatement that is attributable to:
(i) the tax treatment of any item by the taxpayer if there is or was substantial authority for the treatment; or
(ii) any item if the relevant facts affecting the tax treatment of the item are adequately disclosed in the return or in a statement attached to the return and there is a reasonable basis for the tax treatment of the item by the taxpayer.
(4) (a) Except as provided in subsection (4)(b), a person who purposely or knowingly, as those terms are defined in 45-2-101 , fails to file a return or report as required under Title 15 when due or fails to file a return or report within 60 days after receiving written notice from the department that a return or report must be filed is liable for an additional penalty of 15% of the tax due for each month or fraction of a month during which the person purposely or knowingly fails to file a return or report, but not to exceed 75% of the tax due as determined by the department.

(6) A person who files a frivolous return or report under Title 15 is liable, in addition to any other penalty imposed, for a penalty of $2,500. A frivolous return or report is one that is filed by a person and that omits information necessary to determine the taxpayer's tax liability, shows a substantially incorrect tax, is based on a frivolous position, or is based on the taxpayer's action to impede collection of taxes. Frivolous positions are those identified in 26 U.S.C. 6702 as those provisions may apply to provisions of Title 15. The department may bring an action in the name of the state to recover the penalty, interest, and any delinquent taxes.
