Cerro Gordo County supervisors explain proposed levy and answer residents' concerns at public hearing

Cerro Gordo County officials explained the county's proposed property tax levy and answered residents' questions at a public hearing that began at 9:45 a.m. The hearing covered why the state's "truth in taxation" notices have confused some taxpayers, how urban and rural levies differ, and how assessed valuation increases can raise individual tax bills even when the county's proposed rate falls.

Heather, the county budget manager, told attendees the state requires publication of a so-called effective rate that uses current tax dollars applied to next year's taxable value. "The effective rate is an arbitrary rate that the state has come up with that takes the current tax dollars and it uses the upcoming taxable value," she said, and distinguished that from the board's proposed rate. For urban residents the county listed a current rate of $5.33, an effective rate of $4.94 and a proposed county rate of $4.98 — roughly a $0.35 decrease from the current county portion.

Officials emphasized the hearing covered only the Cerro Gordo County levy; separate hearings address levies for Mason City public schools, Mason City and Clear Lake, and other jurisdictions. "There are three different hearings," a supervisor said, noting the county's levy is only one component of a homeowner's total tax bill.

Several residents said their assessed property values have risen substantially over the last decade, which in many cases has increased the taxes they pay. One long-term homeowner said their assessment had "gone up by a huge amount" over 10 years and that, despite a lower proposed county rate, the valuation increase meant their tax payments rose. Officials acknowledged the concern and pointed to the assessor appeals process as the proper remedy for incorrect or disputed assessments. "There is a mechanism for you to dispute your assessment with our county assessor," Heather said.

Staff explained how assessments are made and overseen: assessors typically use neighborhood comparables and transaction data; some counties hire third-party contractors for field work; and, if an assessor does not meet statutory requirements, the state may issue an equalization order. The board reminded residents that county and city assessors now have offices across the alley in the former Dennis building for appeals and questions.

The county also reviewed budget drivers that have affected recent tax levels. Officials said debt service associated with the county's law enforcement center has been a notable factor but that the bond payment is in its final year and is expected to be paid off in June. Supervisors cited rising capital and operating costs — for example, a road grader that cost about $275,000 eight years ago now costs roughly $480,000 — as pressures on future budgets.

Heather presented a breakdown of where property-tax dollars go: roughly 41% to schools, 29% to cities and about 22% to the county, with the remainder going to smaller jurisdictions such as NIACC and townships. The board invited attendees to a more detailed budget hearing on April 27 at 10:00 a.m.

On questions about the county jail, staff said the county has at times housed inmates for surrounding jurisdictions and that those jurisdictions pay housing fees; Cerro Gordo taxpayers are not expected to bear that full external cost. When asked how a proposed data center would affect county taxes, staff said if it were sited in unincorporated county land and generated significant taxable value it could change relative shares, but as proposed the project is being considered on city property and would not affect the county levy in the same way.

The public portion of the hearing closed after attendees asked follow-up questions about exemptions, reassessment frequency and appeals. A motion to adjourn passed by voice vote.
