Assessment Appeal Process

Step 1

Informal Appeals - Contact the county assessor's office as soon as you are notified of your assessment. During an informal meeting with the assessor or one of the staff, you can learn how your assessment was made, what factors were considered, and what type of records pertain to your property. Many disagreements are taken care of at this level.

Step 2

Board of Equalization – If not satisfied after the informal meeting, you should fill out the Boone County Board of Equalization Assessment Appeal form. This form must be returned to the Boone County Clerk postmarked by the third Monday in June (unless extended by the Board of Equalization). The board will hear evidence from the assessor and you regarding the value of the property which is the subject of the appeal.

Step 3

Missouri State Tax Commission – You have a right to appeal the decision of the board of equalization to the State Tax Commission by August 15 in first-class counties (which includes Boone) or St Louis County, and September 30 in other counties or 30 days after the final action of the board of equalization—whichever is later.
