§ 437B.15. 437B.15 Adjustment to assessed value — reporting requirements.

1. a. A taxpayer whose property is subject to the statewide property tax shall report to the director by July 1, 2013, and by May 1 of each subsequent tax year, on forms prescribed by the director, the book value, as of the beginning and end of the preceding calendar year, of all of the following: (1) The local amount of any major addition by local taxing district. (2) The statewide amount of any major addition without notation of location. (3) Any building in Iowa at acquisition cost of more than ten million dollars that was originally placed in service by the taxpayer prior to January 1, 2012, and that was transferred or disposed of in the preceding calendar year, listed by local taxing district. (4) All other taxpayer property without notation of location. (5) The local amount of any major addition eligible for the urban revitalization exemption provided for in chapter 404, by situs. (6) All other transferred taxpayer property, in addition to any transferred property reported under subparagraph (3), listed by local taxing district. (7) Any water utility operating property at acquisition cost of more than one million dollars that was transferred or disposed of in the preceding calendar year, listed by local taxing district. b. For purposes of this section: (1) “Book value” means acquisition cost less accumulated depreciation determined under generally accepted accounting principles. (2) “Taxpayer property” means property described in section 437B.12. (3) “To dispose of” means to sell, abandon, decommission, or retire an asset. (4) “Transfer” means a transaction which results in a change of ownership of taxpayer property and includes a capital lease transaction. c. For purposes of this subsection, “taxpayer” includes a person who would have been a taxpayer in calendar year 2012 had the provisions of this chapter been in effect for the 2012 assessment year. d. If a taxpayer owns or leases pursuant to a capital lease less than the entire interest in a major addition, the local amount and statewide amount, if any, of such major addition shall be apportioned to the taxpayer on the basis of its percentage interest in such major addition. 2. a. Beginning January 1, 2013, the assessed value of taxpayer property shall be adjusted annually as provided in this section. The director, with respect to each taxpayer, shall do all of the following: (1) Adjust the assessed value of taxpayer property in each local taxing district by the change in book value during the preceding calendar year of the local amount of any major addition reported within such local taxing district. (2) Adjust the assessed value of taxpayer property in each local taxing district by allocating the change in book value during the preceding calendar year of the statewide amount and all other taxpayer property described in subsection 1, paragraph “a”, subparagraph (5), to the assessed value of all taxpayer property in the state pro rata according to its preadjustment value. (3) In the case of taxpayer property described in subsection 1, paragraph “a”, subparagraphs (3), (4), and (7), decrease the assessed value of taxpayer property in each local taxing district by the assessed value reported within such local taxing district. (4) In the event of a merger or consolidation of two or more taxpayers, to determine the assessed value of the surviving taxpayer, combine the assessed values of such taxpayers immediately prior to the merger or consolidation. (5) In the event any taxpayer property is eligible for the urban revitalization tax exemption described in chapter 404, adjust the assessed value of taxpayer property within each affected local taxing district to reflect such exemption. (6) In the event the assessed value of taxpayer property is adjusted as a result of taxpayer appeals, reduce the assessed value of taxpayer property in each local taxing district to reflect such adjustment. The adjustment shall be allocated in proportion to the allocation of the taxpayer’s assessed value among the local taxing districts determined without regard to this Fri Dec 12 20:25:57 2025 Iowa Code 2026, Section 437B.15 (17, 0) §437B.15, TAXES ON RATE-REGULATED WATER UTILITIES 2 adjustment. An adjustment to the assessed value of taxpayer property shall be made as of January 1 of the year following the date on which the adjustment is finally determined. b. In no event shall the adjustments set forth in this subsection reduce the assessed value of taxpayer property in any local taxing district below zero. c. The director, on or before October 31 of each assessment year, shall report to the department of management and to the auditor of each county the adjusted assessed value of taxpayer property as of January 1 of such assessment year for each local taxing district. For purposes of this subsection, the assessed value of taxpayer property in each local taxing district subject to adjustment under this section by the director means the assessed value of such property as of the preceding January 1 as determined and allocated among the local taxing districts by the director. d. Nothing in this chapter shall be interpreted to authorize local taxing authorities to exclude from the calculation of levy rates the taxable value of taxpayer property reported to county auditors pursuant to this subsection. e. In addition to reporting the assessed values as described in this subsection, the director, on or before October 31 of each assessment year, shall also report to the department of management and to the auditor of each county the taxable value of taxpayer property as of January 1 of such assessment year for each local taxing district. For purposes of this chapter, “taxable value” means the value for all property subject to the replacement tax annually determined by the director, by dividing the estimated annual replacement tax liability for that property by the current fiscal year’s consolidated taxing district rate for the taxing district where that property is located, then multiplying the quotient by one thousand. A taxpayer who paid more than five hundred thousand dollars in replacement tax in the previous tax year or who believes the taxpayer’s replacement tax liability will vary more than ten percent from the previous tax year shall report to the director by October 1 of the current calendar year, on forms prescribed by the director, the estimated replacement tax liability that will be attributable to all of the taxpayer’s property subject to replacement tax for the current tax year. The department shall utilize the estimated replacement tax liability as reported by the taxpayer or the taxpayer’s prior year’s replacement tax amounts to estimate the current tax year’s taxable value for that property. Furthermore, a taxpayer who has a new major addition of operating property which is put into service for the first time in the current calendar year shall report to the director by October 1 of the current calendar year, or at the time the major addition is put into service, whichever time is later, on forms prescribed by the director, the cost of the major addition and, if not previously reported, shall report the estimated replacement taxes which that asset will generate in the current calendar year. For the purposes of computing the taxable value of property in a taxing district, the taxing district’s share of the estimated replacement tax liability shall be the taxing district’s percentage share of the assessed value allocated by property tax equivalent multiplied by the total estimated replacement tax. The assessed value allocated by property tax equivalent shall be determined by dividing the taxpayer’s current year assessed valuation in a taxing district by one thousand, and then multiplying by the prior year’s consolidated tax rate. 2013 Acts, ch 94, §24, 35, 36 Referred to in §437B.2, 437B.11 Fri Dec 12 20:25:57 2025 Iowa Code 2026, Section 437B.15 (17, 0)
