Iowa Code Title IX. Local Government [Chs. 331-420] § 404B.4. Basis of tax exemption

1. All real property within a disaster revitalization area is eligible to receive a one hundred percent exemption from taxation on the increase in assessed value of the property, as compared to the property's assessed value on January 1, 2007, if the increase in assessed value is attributable to revitalization of the property occurring between May 25, 2008, and December 31, 2013. The exemption is for a period not to exceed five years, starting with an assessment year beginning on or after January 1, 2010.

2. A city or county may adopt a different tax exemption percentage than the exemption provided in subsection 1. The different percentage adopted shall not allow a greater exemption, but may allow a smaller exemption. A different percentage adopted by a city or county shall apply to every disaster revitalization area within the city or county. The owners of real property eligible for the exemption provided in this section shall elect to take the exemption or shall elect to take an eligible exemption provided under another statute. Once the election has been made and the exemption granted, the owner is not permitted to change the method of exemption.
