(5) On motion of the city or county to whom tax is owed, the state board of equalization shall dismiss the appeal of any taxpayer who fails to pay delinquent taxes that have accrued on property that is the subject of the appeal, or who fails to pay at least the undisputed tax related to a properly appealed assessment.

(d)(1) Any tax found refundable following the appeal will accrue interest from the delinquency date at the composite prime rate published by the federal reserve board as of the delinquency date, minus two (2) points.

(2) Sixty (60) days after issuance of the final assessment certificate of the state board of equalization, the interest rate on a deferred refund shall increase two (2) points until the refund is finally paid.

(3) For purposes of this subsection (d), “deferred refund” means the amount owed to the taxpayer, excluding any penalties and interest.
