Cook County Board of Review to Reopen All Townships for Second Round of Property Tax Appeals (Chicago, IL) – In an unusual move prompted by delayed property tax bills and rising financial pressure on households, the Cook County Board of Review announced it will reopen all townships for a second round of property tax appeals for the 2025 session.
The Board of Review, which hears challenges to assessments set by the Cook County Assessor’s Office, typically opens townships in phases and provides a 30-day window for taxpayers to file appeals. Several of those townships had already closed for the year. But officials said “unprecedented circumstances” warranted giving residents another opportunity.
Property tax bills, normally mailed July 1, were not issued until Nov. 14, creating unexpected strain for many homeowners. Board members said the delays spurred their decision to expand the appeal period so more taxpayers could seek relief. Appeals filed during this reopened session will affect 2026 tax bills.
“The ability to file an appeal even though deadlines have closed will be a huge step in helping as many taxpayers as possible exercise their rights,” Commissioner Samantha Steele said. “This year in particular, we have to be creative in finding ways to make the property tax system accessible to as many people as we can.”
The Board will release reopening dates and filing instructions in the coming days. Taxpayers will be able to file online or seek assistance at in-person events across the county.
