As soon as practical after a return is filed, the Department shall examine it to determine the correct amount of tax. If the Department finds that the amount of tax shown on the return is less than the correct amount, it shall notify the taxpayer of the amount of deficiency determined.
If any person fails to file a return, the Department shall estimate the person's liability from any available information and notify the person of the amount of the deficiency determined.
The amount of the deficiency determined shall constitute a final assessment together with interest and penalties thirty (30) days after the date on which notice was mailed to the taxpayer at his or her last known address unless a written protest is filed with the Department within such thirty-day (30-day) period.
The final assessment provision of 013.03 shall constitute a final decision for purposes of the Administrative Procedure Act.
An assessment made by the Department shall be presumed to be correct. In any case when the validity of the assessment is questioned, the burden shall be on the person who challenges the assessment to establish by a preponderance of the evidence that the assessment is erroneous or excessive.
