Illinois's AI hiring law is live. Its notice rules stalled — here's what to do in the gap.
Since January 1, 2026, Illinois employers have been under one of the strictest AI employment laws in the country. House Bill 3773 amended the Illinois Human Rights Act to make two things civil rights violations: using AI in a way that has the effect of discriminating in employment decisions, and failing to tell employees that AI is being used for those decisions at all.
Then the how-to instructions stalled. The Illinois Department of Human Rights proposed notice rules on May 15, 2026, then postponed the rulemaking on June 2, canceling its public hearing to allow for coordination with other state agencies. That leaves employers in an uncomfortable spot: the duty is in force, and the rules explaining how to satisfy it are not.
Who this touches
Any employer using AI anywhere in decisions about Illinois employees or applicants — and "anywhere" is the statute's word choice. The covered list runs from recruitment and hiring through promotion, renewal, discipline, discharge, tenure, and the terms, privileges, and conditions of employment (775 ILCS 5/2-102(L)). That includes the AI scoring résumés inside your applicant-tracking system, whether or not you think of it as "using AI."
What the law actually says
Two provisions matter, and the first is stricter than most coverage conveys.
The discrimination provision is effect-based. It is a civil rights violation to use AI that "has the effect of subjecting employees to discrimination" on protected classes. No intent required. Texas's AI law requires intent to discriminate; California's employment-AI rules allow a business-necessity defense. Illinois wrote neither in: if the tool produces discriminatory outcomes, the violation exists whether or not anyone meant it to. The same provision expressly bans using ZIP codes as a proxy for protected classes.
The notice provision is live but under-specified. Failing to provide notice that AI is used for covered employment purposes is itself a violation, and the statute directed IDHR to write rules on the circumstances, timing, and means of that notice. Those are the rules that stalled. The postponed draft would have required notice to applicants and employees, annual notice to current employees, and notice within 30 days of adopting or substantially changing a covered AI tool. Useful signals of where the agency is headed, but proposed language, not law.
What to do in the gap
- Give notice now. The statutory duty exists today; only the implementation details are pending. A plain-language notice in job postings, the application flow, and the employee handbook ("we use artificial intelligence to assist with [hiring, scheduling, performance] decisions") satisfies the statute's core demand while the details settle. Document when and how you delivered it.
- Build toward the draft rules. The postponed proposal is the best available signal of what final rules will ask: annual employee notice, plus notice within 30 days of adopting or substantially updating a covered tool. Aligning now means minimal rework later. Just track the caveat that proposed language can change.
- Bias-test every covered tool. Under an effect-based standard, intent is irrelevant and testing is the only way to know where you stand. If you operate in multiple states, the same testing program does triple duty: California's regulations and Connecticut's new law both treat anti-bias testing as the evidence that counts, using nearly identical factor language.
- Review what your tools actually ingest. The ZIP-code-proxy ban is feature-level: it reaches the data fields the model uses, even ones that never show up in the output. Ask your vendors what their tools consider, and get the answer in writing.
- Inventory before you attest. The covered-decision list is broad enough that most employers use AI in more places than they realize, usually inside vendor software. You cannot notice, test, or defend a tool you have not identified.
The honest caveat
The draft rules are postponed, not withdrawn, and IDHR has not published a resumption date. Final rules could differ from the proposal, so the annual-notice and 30-day figures above are directional until adoption. What will not change is the statute itself: the effect-based discrimination standard, the proxy ban, and the notice duty have been in force since January 1, and claims can arrive through the state's ordinary discrimination-complaint process in the meantime.
