The Second 2026 Tax Appeal Period Opens

The Second 2026 Tax Appeal Period Opens

By Ali ElSaffar, Oak Park Township Assessor

Oak Park residents concerned about the assessed values of their properties may appeal them with the Cook County Board of Review between August 3 and September 1, 2026.  Residents should know that the Oak Park Township Assessor’s office is available to assist those who wish to file appeals.  Just call (708) 383-8005 to set up an appointment.

2026 Reassessment.  In May of this year, the Cook County Assessor’s office sent reassessment notices to all Oak Park property owners.  These notices proposed new assessed values for each property that would impact the taxes paid by local residents from 2027 through 2029.  Taxpayers unhappy with the proposed values had a right to appeal them to the county assessor’s office, and appeal results were released in mid-July.

Two Appeal Agencies.  Taxpayers dissatisfied with the results from their appeals, as well as taxpayers who did not file an appeal with the Cook County Assessor, now have the right to appeal to the Cook County Board of Review.  There are some differences in the way the two county agencies review tax appeals, such that one agency sometimes denies an appeal while the other grants it.  Thus, if you thought you had a good case but lost your first appeal, don’t give up!

The Oak Park Township Assessor’s office has many experienced staffers who can help local residents quickly and easily file appeals with the Board of Review.  Call before the September 1 deadline and we will work together to get your appeal filed.
