Q: If I mail my assessment complaint to the Board of Review, does it have to arrive in your office by the filing deadline?

A: No, but mailed complaints must be postmarked by the filing deadline for each specific township in order to be considered as timely filed.

Illinois has a specific” which governs this matter. This law provides that if an assessment complaint is “transmitted through the United States mail”, then it “shall be deemed filed with or received by the State or political subdivision on the date shown by the post office cancellation mark stamped upon the envelope or other wrapper containing it.” Note that this provision covers only those complaints sent through the U.S. mail; complaints sent via private carriers are specifically excluded from this provision.
