The total valuation of all properties in Carroll County used for calculating tax rates for Fiscal Year (FY) 2027 has grown to over $1.949 billion. Carroll County Auditor Kourtney Payer presented the data to the supervisors at their meeting this (Monday) morning.
That is an approximately 5.8 percent increase in total valuations across all properties before rollbacks, which vary significantly for residential, agricultural, commercial, industrial, and other classifications. After subtracting tax increment financing (TIF) districts, the county’s total tax base is $1.865 billion. While increases are generally a good thing, Payer says Carroll County’s growth was large enough to trigger an Iowa state law passed several years ago that limits municipal governments’ year-to-year tax collections.
The limitation applies to the General Basic Fund, which will be capped at $6.238 million in FY27. Payer says the Rural Basic Fund will not be subject to the growth reduction.
It is important for taxpayers to remember that the final property tax bill is calculated based on the levies set by all taxing entities. Typically, that would be a combination of the applicable city, county, and school district rates. The supervisors unanimously acknowledged receipt of the valuation report.
