What happens if I missed my township's property tax appeal deadline?

If you missed the initial filing window with the Cook County Assessor’s Office, you likely still have a second opportunity to secure a reduction this year. In Cook County, the appeal process generally offers two distinct stages: Stage 1: The Assessor’s Office: Each township has a specific 30-day window. Stage 2: The Board of Review: Several months after the Assessor’s window closes, your township will open again for appeals at the Board of Review. Why You Should Still Act Immediately: Even if you missed the first deadline, preparing your case now is critical:

• Escalation Support: Our team of lawyers, CPAs, and analysts uses this time to refine evidence, such as algorithm-selected comparables and CPA-certified valuation reports, to ensure a stronger filing at the next level.

• Avoid Future Overpayment: If you miss both windows, you may be stuck with an inflated tax bill for another full year.

• No-Risk Pre-Registration: We can begin our free property tax evaluation today so your appeal is ready for submission the moment the next window opens.
