Iowa Code § 441.24 (2026)

1. If a person refuses to furnish the verified statements required in connection with the assessment of property by the assessor, or to list the corporation’s or person’s property, the department of revenue, or assessor, as the case may be, shall proceed to list and assess the property according to the best information obtainable, and shall add to the taxable valuation one hundred percent thereof, which valuation and penalty shall be separately shown, and shall constitute the assessment; and if the valuation of the property is changed by a board of review, or on appeal from a board of review, a like penalty shall be added to the valuation thus fixed.

2. However, all or part of the penalty imposed under this section may be waived by the board of review upon application to the board by the assessor or the property owner. The waiver or reduction in the penalty shall be allowed only on the valuation of real property against which the penalty has been imposed.
