The Champaign County Board of Review accepts assessment complaints from July 1 to September 10 each year.

How Champaign County Assesses Property
Assessed by: Champaign County Supervisor of Assessments and Township Assessors
Assessment cycle: annual
Notices typically mailed: Spring (typically mid-March to April)
In Champaign County, property is assessed annually at 33.33% (one-third) of its fair market value, as mandated by Illinois law. For example, if your home has a market value of $205,100 (the county median), at Illinois's 33.33% assessment ratio your assessed value would be approximately $68,367. At the county's effective tax rate of 2.07%, this would result in approximately $4,245 in annual property taxes before exemptions.
The Appeal Process
Appeals are heard by the Board of Review. The three-member Board of Review conducts hearings from July 1 through September 10 each year. Hearings may be virtual or in-person at the Brookens Administrative Center, scheduled in 30-minute intervals with time divided between the property owner and the assessor. After September 10, the Board researches values on each complaint and issues written decisions.
Step 1: Contact your local Township Assessor first for an informal review. They are most familiar with your property and may make adjustments based on additional information you provide about your property's condition, features, or recent sales of comparable properties.
Step 2: If the Township Assessor makes no adjustment, obtain the required assessment complaint form from the Champaign County Board of Review office or website. Use the residential property form for single-family homes, with separate forms available for commercial and farm properties.
Step 3: File your formal written complaint with the Champaign County Board of Review between July 1 and September 10. Include supporting evidence such as recent appraisals, comparable sales data, photographs documenting property conditions, or repair estimates for any defects affecting value.
Step 4: Attend your scheduled hearing before the Board of Review. Hearings may be conducted virtually or in-person and are scheduled in 30-minute intervals. Present your evidence clearly and be prepared to explain why your property's assessed value is incorrect or unfair compared to similar properties.
Step 5: Await the Board of Review's written decision, issued after September 10. If denied, you may appeal to the Illinois Property Tax Appeal Board (PTAB), a five-member state panel that reviews local decisions.
Step 6: If the PTAB appeal is unsuccessful, you may file a tax objection complaint in Circuit Court as a final resort. Note that you must pay taxes under protest when pursuing court action, and generally must have first exhausted the Board of Review appeal process.
Required form: Board of Review Assessment Complaint Form (separate forms for residential, commercial, and farm properties)
