Free to check. Nothing is filed on your behalf, and a verdict of "not worth appealing" is the answer we return most often.

A median has half of everything above it by definition, boards do not grant every uniformity claim, and being above a median is a ground to argue rather than proof of error. These are assessed values, not tax bills.

Deadline

30 days from the publication of your township's assessment roll in the local newspaper. The window is short and it is not the same date across the county. Confirm it against your own notice — a late filing cannot be cured.

How to check your own

Type your Waukegan address and you get the verdict, the comparison and the arithmetic — free, without an account. If it says there is nothing there, it says so: roughly a third of properties get told not to file.
