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. Following is a list of several credits and exemptions
available in Iowa.
To qualify for the credit, the property owner must be a resident of Iowa and occupy the property on July 1 and for at
least six months of every year. New applications for homestead tax credit are to be filed with the Assessor on or before
July 1 of the year the credit is first claimed. Once a person qualifies, the credit continues until the property is sold
or until the owner no longer qualifies. This credit reduces the value on which taxes are calculated by a maximum of
$4,850. (Refer to Code of Iowa, Chapter 425)
Application must be made with the Assessor on or before July 1 of the year the exemption is first claimed. The military
certificate of satisfactory service, order transferring to inactive status, reserve, retirement, order of separation
from service or honorable discharge must be recorded in the office of the county recorder. Members of the Reserve Forces
or Iowa National Guard who have served at least 20 years and continue to serve shall record the veteran's retirement
points accounting statement issued by the armed forces of the United States, the state adjutant general, or the adjutant
general of any other state. The exemption from taxation is $2,778 for WWI veterans and $1,852 for all other service
periods. If the qualified veteran does not claim the exemption the spouse, unmarried widow(er), minor child or widowed
parent may be eligible to claim the exemption. (Refer to Iowa Code Chapter 426A)

to the taxable valuation one hundred percent thereof, which valuation and penalty shall be separately shown, and shall
constitute the assessment; and if the valuation of the property is changed by a board of review or on appeal from a
board of review, a like penalty shall be added to the valuation thus fixed.

Market value of a property is an estimate of the price that it would sell for on the open market on January First of
the year of assessment. This is sometimes referred to as the "arms length transaction" or "willing buyer/willing
To estimate the market value of your property, the Assessor generally uses three approaches. The first approach is
to find properties that are comparable to yours which have sold recently. Local conditions peculiar to your property
are taken into consideration. The assessor also uses sales ratio studies to determine the general level of assessment
in a community, in order to adjust for local conditions. This method is generally referred to as the MARKET APPROACH
and usually considered the most important in determining the value of residential property. The second approach is
the COST APPROACH and is an estimate of how many dollars at current labor and material prices it would take to replace
your property with one similar to it. In the event improvement is not new appropriate amounts for depreciation and
obsolescence would be deducted from replacement value. Value of the land then would be added to arrive at the total
estimate of value. The INCOME APPROACH is the third method used if your property produces income such as an apartment
or office building. In that case, your property could be valued according to its ability to produce income under prudent
management; in other words, what another investor would give for a property in order to gain its income. The income
approach is the most complex of the three approaches because of the research, information and analysis necessary for
an accurate estimate of value. This method requires thorough knowledge of local and national financial conditions, as
well as any developmental trends in the area of the subject property being appraised since errors or inaccurate
information can seriously effect the final estimate of value.
State law requires that all real property be reassessed every two years. The current law requires the reassessment to
occur in odd numbered years. Changes in market value as indicated by research, sales ratio studies and analysis of local
conditions as well as economic trends both in and outside the construction industry are used in determining your
If you disagree with the assessor's estimate of value, please consider these two questions before proceeding, as outlined
If you have any questions about the assessment of your property, feel free to come in and discuss it with the Assessor. You
may file a written protest with the Board of Review which is composed of three or five members from various areas of the
assessing jurisdiction. The Board operates independently of the assessor's office, and has the power to confirm or to adjust
either upward or downward any assessment.
If you are not satisfied with the decision of the Board of Review you may appeal to district court within twenty days after
adjournment of said Board, or twenty days after May 31st whichever is the latest.
On values determined as of January 1st, one does not start to pay taxes until eighteen months later. The "roll back"
is the percentage of actual value that is determined by the Director of Revenue and Finance each year on the several
classes of property where the total value increase STATEWIDE, exceeds four percent for each class of property. The
percentage so determined by the Director of Revenue and Finance is certified to and applied by the local county
auditor to all property in each class effected throughout the State. Percentages determined by the Director of
Revenue and Finance are the same for all the assessing jurisdictions in the State.
Increases in assessed value of individual parcels of property as determined by the assessor, may exceed four percent
within a jurisdiction. Agricultural property, except agricultural dwellings, are assessed on the basis of productivity
and net earning capacity using a five-year crop average and capitalized at a rate set by the Legislature. The rate is
currently seven percent. Tentative and final equalization orders are issued by the Director of Revenue and Finance in
odd numbered years on or about August 15th, and October 1st respectively. The orders are sent to the various county
auditors who apply them to the classes of property affected, if any.
Assessors and members of the Board of Review are appointed to their terms of office. Assessors, in addition to completing
the required 150 hours of Continuing Education, must be approved by a majority vote of the Conference Board in order
to be reappointed.
If you desire further information, questions concerning PROPERTY VALUES or other information relating thereto should be
addressed to the assessor's office in the respective jurisdiction and not the Board of Supervisors or Treasurer.
Questions relating to taxes should be addressed to the Warren County Treasurer.
The assessors of Iowa hope that the information contained herein will be of value to the property owner and has clarified
some of these problems and issues relating to assessment and the applicable laws.
There are a number of different taxing districts in a jurisdiction, each with a different levy. Each year the County
Auditor determines for that district a levy that will yield enough money to pay for schools, police and fire protection,
road maintenance and other services budgeted for in that area. 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.
