N.D. Cent. Code § 40-57.1-06
If the capital investment in the buildings, structures, fixtures, and improvements comprising the project exceeds the original investment or total investment after an approved reapplication under this section because expansion of the project has increased the investment in the project by more than twenty percent, the project operator must reapply to receive an exemption or to make payments in lieu of taxes on the added value of the property. If the project operator does not reapply, or if the reapplication is disapproved, the increased capital value of the buildings, structures, fixtures, and improvements comprising the project is subject to ad valorem taxation. If at any time a project operator who is exempt from taxation or subject to payments in lieu of taxes under this chapter moves the business to a new location, the project operator must reapply to retain the remaining balance of the property tax exemption or the option to make payments in lieu of taxes or elect to make application as a new business. A business relocation has no effect on the income tax exemption of the project operator if it is shown by the project operator to the satisfaction of the state board of equalization that the nature of the business has not been changed by the move and that the effect of the business upon competitors has not been changed by the move. In addition, a property tax exemption or option to make payments in lieu of taxes provided by this chapter applies only to the project operator to whom it is granted and is valid only while the property is used for the purposes stated in the application. If there is a change in use of the property or if a new project operator takes possession of the property, the property tax exemption or option to make payments in lieu of taxes terminates and the project operator must file a new application with the municipality for a tax exemption or option to make payments in lieu of taxes for the remainder of the exemption or payments in lieu of taxes period provided under section 40-57.1-03.
