Structural Flaws Drive Unequal Property Tax Burdens, Cook County Official Says (Chicago, IL) – Recent debates over property taxes are highlighting what many Cook County homeowners already know from experience: the system produces clear winners and losers, and the outcomes are far from neutral.
Data from recent reassessment cycles shows that homeowners in predominantly Black and Brown communities on Chicago’s South and West sides have faced property tax increases that far exceed income growth and citywide averages. Those patterns, a member of the Cook County Board of Review says, are not accidental — they are the result of structural problems in how property is assessed.
“As it’s currently designed, the system creates predictable inequities,” said a commissioner on the Board of Review, which hears appeals from property owners who believe their assessments are incorrect. While the board serves as an important safeguard, the commissioner said appeals alone cannot fix a system that builds inequity into assessments from the start.
“A fair system can’t depend on who knows how to file an appeal or who can afford professional help,” the commissioner said. “Equity has to be built into the assessment process itself.”
One of the key reforms being pushed is the creation of a countywide assessment manual with binding standards. Cook County currently lacks a single, enforceable set of rules that governs how properties are assessed across neighborhoods and property types. Without consistent standards, officials say, unequal outcomes are not just possible — they are likely.
Another focus is restoring regular, meaningful physical reassessments of properties. Heavy reliance on computer modeling, the commissioner said, often fails to capture real-world conditions, especially in communities where property quality varies widely. Those errors can snowball over time, deepening disparities.
“A physical reassessment is not a luxury,” the commissioner said. “It’s a tool for equity.”
The commissioner also criticized broad, unfocused reform efforts that produce lengthy reports but little action. Any serious attempt to fix the system, they argued, must be tightly structured and empowered to implement real changes. Chicago, they said, would be a logical place to start, because it clearly shows how state policy, county administration and city finances intersect.
Another proposal is to require regular equity reporting, tracking how tax burdens shift by geography, race, income and property class. When disparities appear, the data should trigger review and corrective action.
Property tax inequities, officials acknowledge, developed over decades and will not be solved by a single reform. But without structural changes — including more consistent standards, physical reassessments and built-in equity checks — the same communities will continue to bear a disproportionate share of the burden.
“The data is already there,” the commissioner said. “The real question is whether those in charge are willing to change the system — intentionally, transparently and with equity as the measure of success.”
