Idaho Statutes Title 63. Revenue and Taxation § 63-503. New and additional assessments

(1) The board of equalization, during its sessions, must direct and require the assessor to assess any property required by this title to be entered upon the property rolls, which is known to have escaped assessment, and in case any assessment of property made by the assessor is deemed by the board of equalization to be so incomplete or inaccurate as to render doubtful the collection of the taxes thereon, the said board must direct the assessor to make a new assessment of such property, in which case the defective assessment shall be cancelled.

(2) All changes in assessments and all new assessments ordered by the board of equalization shall be entered on the property rolls, under the direction of the clerk of the board, and any assessment so changed or entered has the same force and effect as if made and entered by the assessor before the completion of the property rolls.

(3) The county commissioners meeting as a board of equalization shall make no reduction in the assessment of any property when, according to the notation made by the assessor upon the roll, the owner, or his agent or representative, has refused to make the sworn taxpayer's declaration required of him or has willfully concealed, removed, transferred, misrepresented or failed to list such property for the purpose of evading taxation, unless it is shown to the satisfaction of the board that such notation by the assessor is erroneous or false.
