FILING online is available only if you have your new assessment sheet with the account number and pin that was mailed to you.
You may use our convenient drop box located at the public access (North doors) of the courthouse.
This box is shared with the Collector's Office. You may drop off your assessment list and/or your tax payments at any time that suits your schedule.
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.
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.
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.
If at any time you have any questions please don't hesitate to call the office. A member of my staff or myself will be happy to help you.
