All townships within Cook County have two opportunities each year to protest or appeal the assessed valuation on their property. The first opportunity to file an appeal is through the Cook County Assessor’s Office, which establishes a yearly calendar to assign specific dates during which each township is open to file appeals. At the beginning of each tax year, the Assessor’s Office displays a tentative filing date for each township. As the year progresses, the calendar is updated to reflect the actual appeal filing period. A taxpayer may file an appeal only when the township filing period has been established. This filing period lasts approximately 35 days.
The appeals calendar is available on the Cook County Assessor’s website, or taxpayers may call the County Assessor at (312) 443-7550. Taxpayers may also call the Orland Township Assessor’s Office at (708) 403-4712 for more information.
The second opportunity to file an appeal is through the Cook County Board of Review. The Board of Review also publishes a yearly calendar to assign specific dates during which residents of each township may file appeals. This filing period lasts approximately 30 days. The Board of Review calendar, however, is not updated until just prior to each township’s period to file appeals. This calendar may be viewed on the Board of Review’s website or you may call the Board of Review at (312) 603-5542 for appeal filing date information. Taxpayers may also call the Orland Township Assessor’s Office at (708) 403-4712 for more information.
