Assessment Office

From Your Chief County Assessor

Our Mission Statement: To provide fair, accurate, and equitable assessments to all property owners in Rock Island County.

To All Rock Island County Taxpayers

Your township assessor is currently reviewing assessments for the 2023 year, which will be payable in 2024. If you would like to have your assessment reviewed, feel free to contact your township assessor.

Assessments are determined by your township assessor for a four-year period. The four-year period we are currently in is starting with the 2023 assessment year and will continue through the 2026 assessment year.

In the first year of the general assessment period, which is 2023, the Illinois Property Tax Code directs the township assessor "in person or by deputy (to) actually view and determine as near as practicable the value of each property listed for taxation as of January 1 of that year...."

The Property Tax Code informs assessment officials that the property record system shall include up-to-date and complete tax maps, ownership lists, valuation standards (calculation used to value your property) and property record cards, including appraisals, for all or any part of the property in the township. The township assessor maintains property record cards and are available by contacting your township assessor. These records are public records, and shall be available for public inspection during business hours, subject to reasonable rules and regulations of the custodian of the records.

In early fall, we will be mailing a notice of assessments to all taxpayers who receive a change in their 2023 assessment. This notice will provide you with your total assessment. See Assessment Changes.

These assessment changes will also be published in the Dispatch/Argus newspaper at the time of our mailing the assessment notice.

Should you have any questions about the assessment process, feel free to contact me.
