Palos township

2026 is a reassessment year for Palos.

It is in the South/West triad.

The Cook County Assessor's appeal window for Palos has closed for this reassessment.

The Assessor deadline was July 17, 2026.

The Cook County Board of Review is a separate, second venue that opens its own appeal window later in the year, township by township, after the Assessor's window closes. It may still be open or open soon for Palos. Check the Board of Review's dates.

Important: Under 35 ILCS 200/16-120, the Cook County Board of Review has the authority to increase an assessment as well as decrease it. The Assessor's office does not. Filing an appeal there can result in a higher assessment.

Appeal win rates by triad and year

These are observed historical outcomes from the county's own appeals data, for residential class 203. ★ marks each triad's reassessment year. In all four years shown, the triad being reassessed had the highest win rate in the county. This is history, not a prediction of any individual result.

Triad	2021	2022	2023	2024
City	33.1% ★	22.3%	17.7%	25.8% ★
South/West	12.7%	14.3%	23.9% ★	17.4%
North	13.8%	27.8% ★	14.4%	14.7%

Across these years, appeals in a triad's reassessment year succeeded at about 27.6%, versus 15.9% in off years — about 1.74× higher.

Where an appeal can be filed

In Cook County there are two separate places a residential assessment appeal can be filed. Both are free. They are independent of each other. This tool presents both and does not tell you which to use, or whether to use either — that choice is yours.

Cook County Assessor

The office that sets the assessment. It accepts appeals first, during your township's open window.

Filing is free.

The window has closed — the deadline was July 17, 2026.

Cook County Board of Review

A separate elected body. It hears appeals after the Assessor's window closes for your township, in its own window.

Filing is free.

The Board of Review opens township by township after the Assessor's window. Check its published calendar for Palos.

Board of Review status & dates · Board of Review's blank appeal form

This tool links only to the county's own blank forms. It does not fill out, generate, or complete any appeal form, because in Illinois completing a property tax assessment complaint is the practice of law (In re Yamaguchi, 118 Ill. 2d 417 (1987)). It also never contacts the Assessor, the Board of Review, or any county official on your behalf.
