(ii) The amount of the tax imposed which is shown on the return.
(5) The amount of the understatement under paragraph (4) shall be reduced by that portion of the understatement which is attributable to:

(7) The state tax commission may waive all or any part of the addition to tax provided by this section on a showing by the taxpayer that there was reasonable cause for the understatement (or part thereof) and that the taxpayer acted in good faith.
(e) (1) Any person who fails to file a statement of payment to another person required by this chapter, including the duplicate statement of tax withheld on wages, on the date prescribed therefor (including any extension of time for filing) shall, be subject to a penalty of two dollars ($2.00) for each month or part of a month each statement is not so filed, but the total amount imposed on the delinquent person for all such failures during any calendar year shall not exceed two thousand dollars ($2,000).
