Illinois Implements Landmark Insurance Oversight Mandating Prior Approval for Rate Hikes Exceeding 10%

SPRINGFIELD, IL — The Illinois Department of Insurance (IDOI) issued final administrative rules implementing comprehensive prior-approval authority over private auto and homeowners insurance rate adjustments, following landmark consumer protection legislation enacted by Governor JB Pritzker.

Protecting Working Families from Excessive Premium Inflation

The statutory oversight framework ends Illinois’ legacy 'use-and-file' regulatory system, requiring commercial insurance carriers to submit actuarily verified loss ratios to IDOI at least 60 days before implementing rate hikes greater than 10%. The department is equipped with statutory power to reject, modify, or freeze uncompetitive rate adjustments that unfairly penalize working-class ZIP codes in Chicago and downstate communities.

Governor Pritzker stated that working families cannot afford arbitrary insurance rate spikes that outpace inflation, establishing transparent oversight over commercial insurance carriers.

Insurance Industry and Consumer Advocate Perspectives

Consumer advocacy federations celebrated the end of unregulated rate adjustments, estimating working families will save hundreds annually on combined auto and home policies.

Insurance trade groups requested clear timelines for expedited actuarial review of catastrophic storm reinsurance costs.

Implementation Deadlines

All commercial property and casualty rate filings submitted after October 1, 2026, are subject to mandatory IDOI prior-approval review.
