Illinois homeowners are struggling under the weight of the nation’s highest property-tax bills, according to a new analysis.

House Bill 696 would freeze property taxes across the state. Under the plan, local governments could still increase rates, but only with approval from voters. The bill doesn’t apply to home-rule governments, however. That’s no small exemption: 7.8 million Illinoisans live in a home-rule municipality such Chicago, Naperville or Peoria. This number also doesn’t account for Cook County, which is also home-rule, and would be exempted from this property-tax freeze.
