Jo Daviess County reassesses on the state's cycle, and Illinois gives you a real chance to challenge a value you think is wrong — but the clock starts the day the assessment is published, not the day you notice your bill. This works your deadline out from the date on your own notice.
The clock starts at publication, not at your tax bill
Pick which decision you’ve received and enter the date printed on the letter. Everything runs in your browser — nothing is saved or sent.
Choose a decision above to start.
Each township publishes its assessment list once a year, usually in a local newspaper or posted at the township office — this is the notice that starts every clock below, not your tax bill.
Use the Board's own complaint form (available from the Supervisor of Assessments' office) and file it within 30 days of publication. Include comparable-property evidence if you're disputing the value, not just an opinion that it's too high.
The Board of Review schedules a hearing for each complaint and mails a written decision afterward — that decision date starts the next clock.
Within 30 days of the Board's decision, file with the Property Tax Appeal Board (by mail, no fee) or file a tax objection complaint in Jo Daviess County Circuit Court — not both.
This tool is about the assessed VALUE of your property, not your tax bill's rate or your exemptions. If your value is fair but your bill feels high, that's the taxing districts' rates, not something the Board of Review can change — see the property-tax estimator for how the rate is built.

This does the arithmetic and states the published rule — it isn’t legal advice. A deadline that lands on a weekend or holiday may shift, and the body you file with has the final word. When it’s close, file early and confirm with them.
