Do I have to wait for my scheduled reassessment year to file a property tax appeal?
You do not have to wait for a reassessment notice to lower your bill. While the Cook County Assessor uses a triennial, or three-year, cycle, homeowners can challenge their assessment every year.
Your Yearly Opportunities for Savings:
Two Appeals Per Year: In most cases, you can appeal your property twice each year. You can appeal once with the Cook County Assessor. You can also appeal once with the Board of Review.
Dynamic Market Monitoring: Property values in your neighborhood change constantly. Filing an appeal in an "off-year" can lock in a lower value for the remainder of your three-year cycle, preventing you from paying for an outdated, inflated assessment.
Strict 30-Day Windows: Each agency opens a "filing window" for your township that typically stays open for only about 30 days. If you miss the Assessor's window, you must wait for the Board of Review to open later in the season to capture those savings.
