The Cook County Board of Review is reopening the property tax bill appeals window in townships that have closed it for the 2025 appeal season.
The Board typically gives taxpayers in townships a 30-day filing window for appeals. But “unprecedented circumstances” following a four-month delay in mailing second installment bills has led the Board to reopen the window in every closed township, the Board of Review said in a news release Thursday.
Bills are typically mailed July 1. This year they were mailed Nov. 14.
“The delay has placed unexpected financial pressure on many households,” the Board said in the news release. “In recognition of this added strain, the Board determined that expanding the appeal window for this session is a necessary step to ensure more taxpayers have a fair opportunity to seek relief moving forward.”
Appeals filed during this session will be reflected on tax bills issued in 2026.
The Board will announce specific re-opening dates and filing instructions in the coming days, according to the release. Taxpayers will be able to file online or attend in-person assistance events throughout the county.
