My office hosted a property tax appeal workshop in Hillside on Dec. 4 for homeowners seeking property tax relief. Filing an appeal is a free service that cannot increase your property tax bill, but it could potentially decrease your future property tax bills. Although Proviso Township is not being re-assessed this year, all taxpayers can still file an appeal for tax bills to be paid in 2025. The deadline to appeal with our office is Tuesday, Dec. 17.

If you couldn’t join us on the 4th, you can conveniently submit an appeal online by the Dec. 17 deadline by using the following link: appeals.cookcountyboardofreview.com. 

If you’d prefer to file in-person, you can visit our office at 118 N. Clark St. #601, Chicago, IL 60602 between 9 a.m. and 5 p.m. on weekdays. You can also file locally at the Proviso Township Assessor’s Office, 4565 W. Harrison St., Hillside, IL 60624 between 8:30 a.m. and 4 p.m. If you’d like additional information, you can visit us online at www.cookcountyboardofreview.com or give us a call at 312-603-5542.

As one of three commissioners on the Cook County Board of Review, it is my obligation to ensure that property tax valuations are correct. My office is committed to working with all taxpayers. But for the Cook County Board of Review to get values correct, taxpayers must appeal by the deadlines and with understandable evidence.

Thank you to the offices of Village of Hillside Mayor Joe Tamburino, Proviso Township Assessor Steven J. Zawaski, Proviso Township Supervisor Michael Corrigan, Village of Berkeley Mayor Robert Lee, Village of Bellwood Mayor Andre Harvey, Village of Broadview Mayor Katrina Thompson, Village of Westchester President Greg Hribal, 16th District Cook County Commissioner Frank Aguilar, 17th District Cook County Commissioner Sean Morrison, and 1st District Cook County Commissioner Tara Stamps, all of whom helped organize our Dec. 4 appeal workshop to help taxpayers with the appeal process.

This event was the continuation of the work being done by our office. We will keep working with taxpayers throughout the appeal process while striving to ensure fair property tax assessments.
