UNDERSTANDING YOUR ASSESSMENT

Why am I receiving an assessment notice?

Iowa law requires all property to be revalued every two years to reflect changes in market value and to keep up with market trends.  Research of sales ratio studies, analysis of local conditions, and construction costs are used in determining assessments.  The assessed value represents the value as the property sits as of January 1, 2021.  Each property owner is notified any time there is a change in value to their property.

Does the assessor raise my value according to the amount of taxes needed?

No, the assessor raises or lowers property values according to the market value of real estate, or in the case of agricultural land, according to productivity and CSR2s (soil ratings).  Assessments are set January 1 of each year, while the rollback and tax levies on these assessments are not set until July of the following year.  The percentage of increase or decrease in valuation is not directly tied to the percentage of increase or decrease in taxes the following year.  The tax ask is determined by the levying authorities - school boards, city councils, and county supervisors.

If the assessor of a jurisdiction fails to revalue properties within the allowed parameters set by the Iowa Department of Revenue, the Department will send equalization orders to the jurisdiction's auditor to make the required changes themselves.

I disagree with my value.  What can I do?

Revaluations are set by market trends and done in mass.  This means that properties are revalued by specific groups (like cities, townships, or even neighborhoods) and not on an individual, parcel-by-parcel basis.  However, individual property assessments can be done at any time by simply setting up an appointment with a field appraiser from the assessor's office.  Many times we are not aware of a condition change; we rely on property owners to make us aware of such changes.

  • If you do not believe your value is current market value, your first option might be to file an informal assessment review within the assessor's office.  In this case, an appointment would be made with a field appraiser and a possible new value could be agreed upon, all without having to go through the formal protest process with the Board of Review.  Forms for this review are available in the assessor's office.  This process of appointment, informal review, agreement, and final signing of the form must be completed between April 2 and April 25.
  • If you do not believe your value is current market value, you may choose to protest with the county Board of Review.  In this case, a petition form would be filed with the Board of Review in the assessor's office, and you would have the option to have an oral hearing before the Board or to simply have them review any information you turn in with the petition.  Petition forms are available in the assessor's office or online on the Marion County Website (www.co.marion.ia.us) or Iowa Department of Revenue website (https://tax.iowa.gov).  Petitions must be timely filed with the Board of Review in the assessor's office between April 2 and April 30.
