When does the Lyons Township appeal window open and close?

The 2026 window opens May 6, 2026 and closes June 9, 2026. After it closes, the next opportunity to formally appeal will be in 2029 (Cook County reassesses each township once every three years).

What's the deadline to file an appeal in Lyons?

What does it cost to appeal?

The Cook County Board of Review charges no fee. OverTaxed IL offers a $69 DIY Appeal Packet, $97 Done-For-You filing after explicit authorization, and a 22% contingency option for eligible cases. You can also file on your own at no cost — see the pricing details.

What evidence do I need to appeal in Lyons?

The Board of Review accepts comparable assessments, relevant sales evidence, lack-of-uniformity arguments (your assessment vs. similar properties), and condition-based evidence (recent photos, contractor estimates). We pull public-record comparable properties from Lyons and surrounding townships automatically when you run a free check.

Will appealing increase my taxes?

No. The Board of Review can confirm or lower your assessed value but cannot raise it as a result of your appeal. The worst case is your assessment stays the same.
