County Assessor


The Assessor's Office puts values on all Real Estate and Personal Property owned on January 1st of the year.

53.030 Every assessor shall take an oath or affirmation to support the Constitution of the United States and of this state, and to demean himself faithfully in office and to assess all of the real and tangible personal property in the county in which he assesses at what he believes to be the actual cash value.  He shall endorse this oath on his certificate of election or appointment before entering upon the duties of his office.
​
I ask that you please be respectful to my staff.  They are doing their job.

Personal Property:
            If you're new to the county please call or come in so we can get you on our rolls.
             If you lived in Cooper County and owned a vehicle on January 1st you will need to fill out an Assessment List.
             Please call office 660-882-2646 for assistance.
        

Real Estate: 
             Unless you have a change of address real estate is automatic.  Once your deed is recorded we will get the transfer information and the ownership name will be changed.

Documents and Forms

Assessment list-mailed around January 1st to list vehicles etc. 
Due back to Assessor's Office March 1st. 

Impact Notices-notification to taxpayer that the assessed value of your real estate has increased.  Mailed the middle of June.  If you receive an Impact Notice in the mail you need to open it immediately and look at the value if you do not think that your property is worth the value that I have assessed, then you need to call or make an appointment right away.  If you wait until after July your value will not get changed until the next years taxes. Remember that the Assessor's Office determines the value of the property not taxes.

Sales letters-mailed to real estate with new ownership and the seller of said real estate on a monthly basis.  This letter and the requested information is used to update real estate and gives a better idea of market value in Cooper County.  Please return as soon as possible after you have received it.
