The assessed value of all properties is based on current market value with the exception of agricultural classed parcels. The values are based on current sales data as well as site visits when applicable. This value is determined in the Assessor’s office.
The taxable value of a property is the percentage of the assessed value that will carry a tax burden. The Iowa Director of Revenue and Finance determines the "rollback" percentage for each class of property annually. The rollback percentage is the same for every jurisdiction within the state. This value is calculated in the Auditor’s office.
