(1) If the department determines that the tax reported by a licensee is deficient, the department shall assess the deficiency on the basis of information available to it, and shall add a penalty of two percent of the amount of the deficiency.

     (2) If a licensee, or person acting as such, fails, neglects, or refuses to file a motor vehicle fuel tax report the department shall, on the basis of information available to it, determine the tax liability of the licensee or person for the period during which no report was filed. The department shall add the penalty provided in subsection (1) of this section to the tax. An assessment made by the department under this subsection or subsection (1) of this section is presumed to be correct. In any case, where the validity of the assessment is questioned, the burden is on the person who challenges the assessment to establish by a fair preponderance of evidence that it is erroneous or excessive, as the case may be.

     (3) If a licensee or person acting as such files a false or fraudulent report with intent to evade the tax imposed by this chapter, the department shall add to the amount of deficiency a penalty equal to twenty-five percent of the deficiency, in addition to the penalty provided in subsections (1) and (2) of this section and all other penalties prescribed by law.

     (4) Motor vehicle fuel tax, penalties, and interest payable under this chapter bears interest at the rate of one percent per month, or fraction thereof, from the first day of the calendar month after the amount or any portion of it should have been paid until the date of payment. If a licensee or person acting as such establishes by a fair preponderance of evidence that the failure to pay the amount of tax due was attributable to reasonable cause and was not intentional or willful, the department may waive the penalty. The department may waive the interest when it determines the cost of processing or collection of the interest exceeds the amount of interest due.

     (5) Except in the case of a fraudulent report, neglect or refusal to make a report, or failure to pay or to pay the proper amount, the department shall assess the deficiency under subsection (1) or (2) of this section within five years from the last day of the succeeding calendar month after the reporting period for which the amount is proposed to be determined or within five years after the return is filed, whichever period expires later.

     (6) Except in the case of violations of filing a false or fraudulent report, if the department deems mitigation of penalties and interest to be reasonable and in the best interest of carrying out the purpose of this chapter, it may mitigate such assessments upon whatever terms the department deems proper, giving consideration to the degree and extent of the lack of records and reporting errors. The department may ascertain the facts regarding recordkeeping and payment penalties in lieu of more elaborate proceedings under this chapter.

     (7) A licensee or person acting as such against whom an assessment is made under subsection (1) or (2) of this section may petition for a reassessment within thirty days after service upon the licensee of notice of the assessment. If the petition is not filed within the thirty-day period, the amount of the assessment becomes final at the expiration of that period.

     If a petition for reassessment is filed within the thirty-day period, the department shall reconsider the assessment and, if the petitioner has so requested in its petition, shall grant the petitioner an oral hearing and give the petitioner twenty days' notice of the time and place of the hearing. The department may continue the hearing from time to time. The decision of the department upon a petition for reassessment becomes final thirty days after service of notice upon the petitioner.

     An assessment made by the department becomes due and payable when it becomes final. If it is not paid to the department when due and payable, the department shall add a penalty of ten percent of the amount of the tax.

     (8) In a suit brought to enforce the rights of the state under this chapter, the assessment showing the amount of taxes, penalties, interest, and cost unpaid to the state is prima facie evidence of the facts as shown.

     (9) A notice of assessment required by this section must be served personally or by certified or registered mail. If it is served by mail, service shall be made by deposit of the notice in the United States mail, postage prepaid, addressed to the respondent at the most current address furnished to the department.
