Can I appeal beyond the Board of Review?

Yes. If you disagree with the decision from the Cook County Board of Review, you may continue your property tax appeal with the Illinois Property Tax Appeal Board (PTAB).

PTAB is a state-level agency that reviews property tax assessment disputes after the local appeal process has been completed.

This option is available to both Cook County homeowners and commercial property owners.


What Is the Illinois Property Tax Appeal Board (PTAB)?

The Illinois Property Tax Appeal Board (PTAB) is an independent state agency that reviews property tax assessment decisions made by county boards of review.

PTAB provides another level of review when property owners believe their assessment is still too high after the Board of Review decision.

PTAB may:

  • Review the evidence from the previous appeal

  • Request additional documentation

  • Adjust the property’s assessed value if justified


When Can You File a PTAB Appeal?

You can file a PTAB appeal after receiving the final decision from the Cook County Board of Review.

To qualify, you must have already filed an appeal with the Board of Review.

If you did not file at the Board of Review level, you generally cannot file with PTAB.


PTAB Filing Deadline

Property owners must file with PTAB within 30 days after the Board of Review issues its final decision.

Missing this deadline usually means you cannot continue the appeal for that tax year.


What Evidence Is Needed for a PTAB Appeal?

PTAB appeals typically require strong supporting documentation.

Examples include:

  • Comparable property sales

  • Property appraisal reports

  • Income and expense statements for commercial properties

  • Evidence previously submitted to the Board of Review

Because PTAB reviews evidence carefully, detailed documentation is important.


Another Option: Circuit Court Appeal

In some cases, property owners may also pursue a tax objection complaint in circuit court after paying the property tax bill.

This process is more complex and typically requires legal representation.
