There are a number of different taxing districts in a jurisdiction, each with a different levy. Each year the County Auditor determines a levy for each district that will yield enough money to pay for schools, police and fire protection, road maintenance and other services budgeted. The tax levy is applied to each $1,000 of a property's taxable value.

The value determined by the assessor is the assessed value and is the value indicated on the assessment roll.  The taxable value is the value determined by the auditor after application of state ordered "rollback" percentages for the various classes of property and is the value indicated on the tax statement.

When comparing the value of your property with other properties always compare with the value on the assessment roll or the assessor's property record cards and not the value indicated on the tax statement.

Credits and Exemptions

Iowa law provides for a number of credits and exemptions. It is the property owner's responsibility to apply for these as provided by law. It is also the property owner's responsibility to report to the Assessor when they are no longer eligible for any credit or exemption they have applied for.

Government owned property (Public school/City/County/State/Federal)

All federally owned properties are completely exempt from taxation. State owned property is also exempt, except in a few rare instances.

Iowa law allows religious and charitably owned property to be full exempt from taxes. In order for the property to be exempt, it must be solely used for religious or charitable purposes. Being an IRS 501(c)3 nonprofit entity does not qualify a charitable property for exemption, as there still needs to be a charitable use in addition to the non-profit status.

Rivers and Streams Exemption - Sign up deadline: February 1
