The commissioner may recover the amount of any tax due and unpaid under this chapter, as well as interest, and any penalty in a civil action. The collection of the tax, interest, or penalty is not a bar to any prosecution under this chapter.
If a tax imposed by this chapter is not paid within the time specified for payment, a penalty is added to the amount required to be shown as tax. The penalty is five percent of the tax not paid on or before the date specified for payment of the tax if the failure is for not more than 30 days, with an additional penalty of five percent of the amount of tax remaining unpaid during each additional 30 days or fraction of 30 days during which the failure continues, not exceeding 15 percent in the aggregate.
If a taxpayer fails to make and file a return within the time prescribed, including an extension, a penalty of five percent of the amount of tax not timely paid is added to the tax.
If part of an additional assessment is due to negligence or intentional disregard of the provisions of the applicable tax laws or rules of the commissioner, but without intent to defraud, there must be added to the tax an amount equal to ten percent of the additional assessment.
If there is a pattern by a person of repeated failures to timely file returns or timely pay taxes, and written notice is given that a penalty will be imposed if such failures continue, a penalty of 25 percent of the amount of the tax not timely paid as a result of each such subsequent failure is added to the tax. The penalty can be abated under the abatement authority in section 270C.34.
If a person files a false or fraudulent return, or attempts in any manner to evade or defeat a tax or payment of tax, there is imposed on the person a penalty equal to 50 percent of the tax due for the period to which the return related, less amounts paid by the person on the basis of the false or fraudulent return.
The penalties imposed by this section are collected and paid in the same manner as taxes.
The civil penalties imposed by this section are in addition to the criminal penalties imposed by this chapter.
