Your County Assessor, Alicia Degase

Welcome to the Douglas County Assessor's homepage. The County Assessor's Office strives to provide the best service to the taxpayers of Douglas County. As your Douglas County Assessor, I would like to welcome you to our website. Please call our office if you have any questions. We are glad to provide you with any help and assistance that you may need.


The Assessor's job is to place value on all taxable real and personal property, within the county as of January 1st, the assessment date set by the State Statute. All county assessors' offices are regulated and overseen by the Missouri State Tax Commission. Monthly visits by field representatives and annual spot reviews of properties, aid them in evaluating the Assessor's compliance with the statue requirements. This includes real estate and personal property of all individuals and businesses.

The assessed value, as determined by the Assessor's office, is a percentage of the market value of the property. The assessment percentage is set by state law and determined by the classification of the property. The classification and assessment rates of real property include Agricultural 12%, Residential 19% and Commercial properties at 32%. The assessed property value is one part of the formula in determining property taxes, with the other factor being a tax rate or levy, which is determined by the various taxing entities and jurisdictions.
