Questions

Palos Township appeals: common questions

When is the Palos Township appeal deadline?

For tax year 2026, the Cook County Assessor window for Palos Township opened 03 Jun 2026 and closes 17 Jul 2026. We last verified that date against the office’s published calendar on 25 Sep 2026; dates move, so confirm with the office before you file.

What are the odds an appeal in Palos Township works?

In tax year 2025, 13.2% of the 2,148 closed residential appeals the Assessor decided for Palos Township changed the assessed value, and 28.4% of the 3,625 residential appeals the Board of Review decided ended in a decrease. Those are township-wide rates from closed cases, not a prediction for any one property.

Should I appeal to the Assessor or the Board of Review in Palos Township?

They are separate filings and the table above shows both. For 2025, Palos Township sent 2,148 residential appeals to the Assessor and 3,625 to the Board of Review; 13.2% and 28.4% of them respectively moved the value. The Board of Review hears appeals after the Assessor has closed a township, so missing the first window does not end the year.

How much did assessments go up in Palos Township?

At the 2026 reassessment the median residential assessment rose 23.3%, measured across the 20,470 class-2 properties the Assessor valued in both 2025 and 2026. That is the middle of the township, not your property: half the homes moved more.

What if the Palos Township window has already closed?

Nothing on this page files an appeal for you, and a closed window can’t be reopened here. The figures above are per tax year, so the same tables tell you what the next year’s filing looks like; the free assessment check compares your home with near-identical homes nearby whenever you run it.

Every answer here restates a figure printed elsewhere on this page. Nothing is added that we haven’t measured and sourced.
