For subsequent fiscal years, the limitation on the maximum acreage of real property that may be granted exemptions shall be the limitation for the previous fiscal year, unless the amount of acreage granted exemptions for the previous fiscal year equaled the limitation for that year, then the limitation for the subsequent fiscal year is the limitation for the previous fiscal year plus an increase, not to exceed three hundred acres, of ten percent of that limitation. The procedures of this subsection shall be followed for each assessment year to procure an exemption for the fiscal year beginning in the assessment year. The exemption shall be only for the fiscal year for which it is granted. A parcel of property may be granted subsequent exemptions. The exemption shall only be granted for parcels of property of two acres or more.a.  Application for this exemption shall be filed with the commissioners of the soil and water conservation district in which the property is located, not later than February 1 of the assessment year, on forms provided by the department of revenue.

In the case of an open prairie which is or includes a gully area susceptible to severe erosion, an approved erosion control plan must accompany the application.b.  Upon receipt of the application, the commissioners shall certify whether the property is eligible to receive the exemption. The commissioners shall not withhold certification of the eligibility of property because of the existence upon the property of an abandoned building or structure which is not used for economic gain. If the commissioners certify that the property is eligible, the application shall be forwarded to the board of supervisors by May 1 of that assessment year with the certification of the eligible acreage. An application must be accompanied by an affidavit signed by the applicant that if an exemption is granted, the property will not be used for economic gain during the assessment year in which the exemption is granted.c.  In the case of an open prairie that has been restored or reestablished and that does not receive the certification as provided by the county board of supervisors as it relates to the ground cover, the applicant shall be notified of the availability of resource enhancement and protection fund cost-share moneys and soil and conservation technological assistance for reestablishing native vegetation.d.  Before the board of supervisors may designate real property for the exemption, it shall establish priorities for the types of real property for which an exemption may be granted and the amount of acreage. These priorities may be the same as or different than those for previous years. The board of supervisors shall get the approval of the governing body of the city before an exemption may be granted to real property located within the corporate limits of that city. A public hearing shall be held with notice given as provided in section 73A.2 at which the proposed priority list shall be presented. However, no public hearing is required if the proposed priorities are the same as those for the previous year. After the public hearing, the board of supervisors shall adopt by resolution the proposed priority list or another priority list. Property upon which are located abandoned buildings or structures shall have the lowest priority on the list adopted, except where the board of supervisors determines that a structure has historic significance. The board of supervisors shall also provide for a procedure where the amount of acres for which exemptions are sought exceeds the amount the priority list provides for that type or in the aggregate for all types.e.  After receipt of an application with its accompanying certification and affidavit and the establishment of the priority list, the board of supervisors may grant a tax exemption under this subsection using the established priority list as a mandate. Real property designated for the tax exemption shall be designated by May 15 of the assessment year in which begins the fiscal year for which the exemption is granted. Notification shall be sent to the county auditor and the applicant.f.  The board of supervisors does not have to grant tax exemptions under this subsection, grant tax exemptions in the aggregate of the maximum acreage which may be granted exemptions, or grant a tax exemption for the total acreage for which the applicant requested the exemption. Only real property in parcels of two acres or more which is recreational lakes, forest cover, river and stream, river and stream banks, or open prairie and which is utilized for the purposes of providing soil erosion control or wildlife habitat or both, and which is subject to property tax for the fiscal year for which the tax exemption is requested, is eligible for the exemption under this subsection. However, in addition to the above, in order for a gully area which is susceptible to severe erosion to be eligible, there must be an erosion control plan for it approved by the commissioners of the soil and water conservation district in which it is located. In the case of an open prairie that has been restored or reestablished, the property shall be inspected and certified as provided by the county board of supervisors as having adequate ground cover consisting of native species and that all primary and secondary noxious weeds present are being controlled to prevent the spread of seeds by either wind or water. In the case of an exemption for river and stream or river and stream banks, the exemption shall not be granted unless there is included in the exemption land located at least thirty-three feet from the ordinary high water mark of the river and stream or river and stream banks. Property shall not be denied an exemption because of the existence upon the property of an abandoned building or structure which is not used for economic gain. If the real property is located within a city, the approval of the governing body must be obtained before the real property is eligible for an exemption. For purposes of this subsection:(1)  “Open prairies” includes hillsides and gully areas which have a permanent grass cover but does not include native prairies meeting the criteria of the natural resource commission.(2)  “Forest cover” means land which is predominantly wooded.(3)  “Recreational lake” means a body of water, which is not a river or stream, owned solely by a nonprofit organization and primarily used for boating, fishing, swimming, and other recreational purposes.(4)  “Used for economic gain” includes, but is not limited to, using property for the storage of equipment, machinery, or crops.g.  Notwithstanding other requirements under this subsection, the owner of any property lying between a river or stream and a dike which is required to be set back three hundred feet or less from the river or stream shall automatically be granted an exemption for that property upon submission of an application accompanied by an affidavit signed by the applicant that if the exemption is granted the property will not be used for economic gain during the period of exemption. The exemption shall continue from year to year for as long as the property qualifies and is not used for economic gain, without need for filing additional applications or affidavits. Property exempted pursuant to this paragraph is in addition to the maximum acreage applicable to other exemptions under this subsection.23.Native prairie and wetland.Land designated as native prairie or land designated as a protected wetland by the department of natural resources pursuant to section 456B.12.a.  Application for the exemption shall be made on forms provided by the department of revenue. Land designated as a protected wetland shall be assessed at a value equal to the average value of the land where the wetland is located and which is owned by the person granted the exemption. The application forms shall be filed with the assessing authority not later than the first of February of the year for which the exemption is requested. The application must be accompanied by an affidavit signed by the applicant that if the exemption is granted, the property will not be used for economic gain during the assessment year in which the exemption is granted. If the property is used for economic gain during the assessment year in which the exemption is granted, the property shall lose its tax exemption and shall be taxed at the rate levied by the county for the fiscal year beginning in that assessment year. The first annual application shall be accompanied by a certificate from the department of natural resources stating that the land is native prairie or protected wetland. The department of natural resources shall issue a certificate for the native prairie exemption if the department finds that the land has never been cultivated, is unimproved, is primarily a mixture of warm season grasses interspersed with flowering plants, and meets the other criteria established by the natural resource commission for native prairie. The department of natural resources shall issue a certificate for the wetland exemption if the department finds the land is a protected wetland, as defined under section 456B.1, or if the wetland was previously drained and cropped but has been restored under a nonpermanent restoration agreement with the department or other county, state, or federal agency or private conservation group. A taxpayer may seek judicial review of a decision of the department according to chapter 17A. The natural resource commission shall adopt rules to implement this subsection.b.  The assessing authority each year may submit to the department a claim for reimbursement of tax revenue lost from the exemption. Upon receipt of the claim, the department shall reimburse the assessing authority an amount equal to the lost tax revenue based on the value of the protected wetland as assessed by the authority, unless the department reimburses the authority based upon a departmental assessment of the protected wetland. The authority may contest the department’s assessment as provided in chapter 17A. The department is not required to honor a claim submitted more than sixty days after the authority has assessed land where the protected wetland is located and which is owned by the person granted the exemption.24.Land certified as a wildlife habitat.a.  The owner of agricultural land may designate not more than two acres of the land for use as a wildlife habitat. After inspection, if the land meets the standards established by the natural resource commission for a wildlife habitat under section 483A.3, and, in the case of a wildlife habitat that has been restored or reestablished, is inspected and certified as provided by the county board of supervisors as having adequate ground cover consisting of native species and that all primary and secondary noxious weeds present are being controlled to prevent the spread of seeds by either wind or water, the department of natural resources shall certify the designated land as a wildlife habitat and shall send a copy of the certification to the appropriate assessor not later than February 1 of the assessment year for which the exemption is requested. The department of natural resources may subsequently withdraw certification of the designated land if it fails to meet the established standards for a wildlife habitat and the ground cover requirement and the assessor shall be given written notice of the decertification.b.  In the case where the property is a restored or reestablished wildlife habitat and does not receive the certification as provided by the county board of supervisors as it relates to the ground cover, the owner shall be notified of the availability of resource enhancement and protection fund cost-share moneys and soil and conservation technological assistance for reestablishing native vegetation.25.  Reserved.26.Public television station.All grounds and buildings used or under construction for a public television station and not leased or otherwise used or under construction for pecuniary profit.27.Speculative shell buildings of certain organizations.a.  New construction of shell buildings by community development organizations, not-for-profit cooperative associations under chapter 499, or for-profit entities for speculative purposes as provided in this subsection.b.  The exemption shall be for one of the following:(1)  The value added by new construction of a shell building or addition to an existing building or structure by a community development organization, not-for-profit cooperative association under chapter 499, or for-profit entity.(2)  The value of an existing building being reconstructed or renovated, and the value of the land on which the building is located, if the reconstruction or renovation constitutes complete replacement or refitting of the existing building or structure, by a community development organization, not-for-profit cooperative association under chapter 499, or for-profit entity.c.  The exemption or partial exemption shall be allowed only pursuant to ordinance of a city council or board of supervisors, which ordinance shall specify if the exemption will be available for community development organizations, not-for-profit cooperative associations under chapter 499, or for-profit entities. If the exemption is for a project described in paragraph “b”, subparagraph (1), the exemption shall be effective for the assessment year in which the building is first assessed for property taxation or the assessment year in which the addition to an existing building first adds value. If the exemption is for a project described in paragraph “b”, subparagraph (2), the exemption shall be effective for the assessment year following the assessment year in which the project commences. An exemption allowed under this subsection shall be allowed for all subsequent years until the property is leased or sold or for a specific time period stated in the ordinance or until the exemption is terminated by ordinance of the city council or board of supervisors which approved the exemption. Eligibility for an exemption as a speculative shell building shall be determined as of January 1 of the assessment year.

427.2Taxable property acquired through eminent domain.1.  Real estate occupied as a public road, and rights-of-way for established public levees and rights-of-way for established, open, public drainage improvements shall not be taxed.2.  When land or rights in land are acquired in connection with or for public use or public purposes, the acquiring authority shall assist in the collection of property taxes and special assessments. However, assistance in the collection of the property taxes does not require the payment of property taxes on the property acquired which exceed the amount of just compensation offered as required by section 6B.45 for the acquisition of the property.3.  The property owner shall pay all property taxes which are due and payable when the property owner surrenders possession of the property acquired and also those which become due and payable for the fiscal year the property is acquired in an amount equal to one-twelfth of the taxes due and payable on the property acquired for the preceding fiscal year multiplied by the number of months in the fiscal year in which the property was acquired which elapsed prior to the month in which the property owner surrenders possession, and including that month if the surrender of possession occurs after the fifteenth day of a month. For purposes of computing the payments, the property owner has surrendered possession of property acquired by eminent domain proceedings when the acquiring authority has the right to obtain possession of the acquired property as authorized by law. When all of the property is acquired for public use or public purposes, the property owner shall pay all special assessments in full which have been certified to the county treasurer for collection before the possession date of the acquiring authority. When part but not all of the property is acquired for public use or public purposes, taxing authorities may collect property taxes and special assessments which the property owner is obligated to pay, in accordance with chapter 446, from that part of the property which is not acquired. The county treasurer shall collect and accept the payment received on property acquired for public use or public purposes as full and final payment of all property tax on the property.4.  For that portion of the prorated year for which the acquiring authority has possession of the property or part of the property acquired in connection with or for public use or public purposes, all taxes shall be canceled by the county treasurer.5.  From the date of possession by the acquiring authority for land or rights in land acquired in connection with or for public use or public purposes, and for as long as ownership is retained by the acquiring authority, a special assessment shall not be certified to the county treasurer for collection while under public ownership. However, the assessment may be certified for collection to the county treasurer upon the sale of the acquired property by the acquiring authority to a new owner on a prorated basis. Special assessments certified to a county treasurer for collection while under public ownership shall be canceled by the county treasurer.6.  Upon sale of the acquired property by the acquiring authority to a new owner, the new owner shall pay all property taxes which become due and payable or would have become due and payable but for the acquisition by the acquiring authority for the fiscal year the property is acquired by the new owner in an amount equal to one-twelfth of the taxes multiplied by the number of months in the fiscal year in which the new owner acquired the property which occurred after the month in which the new owner acquired the property.[C73, §809; C97, §1344; C24, 27, 31, 35, 39, §6945; C46, 50, 54, 58, 62, 66, 71, 73, 75, 77, 79, 81, §427.2; 1982 Acts, ch 1183, §1]86 Acts, ch 1153, §1, 87 Acts, ch 40, §1, 2016 Acts, ch 1011, §121427.2ATaxation of life estate in property donated to public.1.  Real estate donated to the state or a political subdivision of the state or any agency of the state or political subdivision, for which the donor retains a life estate, or provides for another to possess a life estate shall continue to be subject to property taxation and special assessment to the same extent as the property was so subject during the fiscal year in which the donation was made. The real property shall continue to be taxed until the fiscal year following the fiscal year during which the life estate terminates. Upon termination of the life estate, the real estate shall be subject to taxation as otherwise provided by law.2.  This section applies to property donated on or after July 1, 1992, for purposes of property taxes or special assessments due and payable in fiscal years beginning on or after July 1, 1997.97 Acts, ch 146, §1, 2002 Acts, ch 1119, §168, 2019 Acts, ch 24, §104
