North Dakota Century Code Title 57. Taxation § 57-33.2-20. Penalty

If any company refuses or neglects to make the reports required by this chapter, or refuses or neglects to furnish any information requested, the commissioner shall use the best facts and estimates available to determine the tax due. The tax must be imposed upon the basis of that information. If any company fails to make the report required under this chapter on or before the first day of June of any year, the state board of equalization shall add a penalty of ten percent of the tax due for failure to make the required report which must be collected as a part of the tax, but the commissioner, upon application, may grant extensions of time within which the returns must be filed. For good cause shown, the commissioner may waive all or any part of the penalty that attached under this section.
