Fair cash value = certified assessed value × 10 (Illinois law: residential properties assessed at 10% of FCV).
What it means
In plain terms: your home is assessed higher than comparable nearby homes, which means your annual property tax bill is likely higher than it should be. You have the right to challenge it.
Illinois law requires all residential properties in Cook County to be assessed at a consistent rate relative to comparable homes. When your assessed value per square foot is meaningfully higher than your neighbors', you're paying more than your fair share — and you have the right to appeal to the Cook County Board of Review.
