Township Assessors

Each township has an elected assessor that appraises property. The assessed value of the property becomes the tax base upon which local agencies levy taxes. In Illinois, a legal assessment is 33 1/3%of market value. The assessor does not determine how much your taxes are; rather, by placing a value on property, he/she is distributing the overall tax burden among all the property owners. The actual dollar amount of your tax bill is determined by how much money each local agency needs to operate. A list of Ogle County’s township assessors follows.

In most cases, your assessor places the initial assessment on your property. That information is then submitted to this office for processing, deducting exemptions, etc. Questions regarding buildings and other improvements should be directed to the appropriate township assessor. Your township assessor can also address any questions or concerns you may have about your assessed value.
