Does Illinois HB 3773 Apply to Your Company? A Plain-English Guide for Employers

If you employ people in Illinois and you use any form of AI in hiring or other employment decisions, Illinois HB 3773 almost certainly applies to you — and it has been in effect since January 1, 2026. This guide explains, in plain English, what the law requires, who it covers, what counts as "AI," where most companies are exposed right now, and what to do about it.

What is Illinois HB 3773?

HB 3773 amended the Illinois Human Rights Act (IHRA) to address the use of artificial intelligence in employment. In short, it makes two things clear:

(1) It is a civil rights violation for an employer to use AI in a way that discriminates against employees or applicants on the basis of a protected class — whether or not the discrimination was intentional.

(2) Employers must provide notice when AI is used in connection with employment decisions.

Because these protections live inside the Illinois Human Rights Act, they carry the IHRA's enforcement machinery — including a private right of action. That's the part most employers underestimate.

Who does HB 3773 apply to?

The law applies broadly to Illinois employers. As a practical matter, if you have one or more employees in Illinois and you use AI to help make employment decisions — hiring, promotion, discipline, termination, or similar — you should assume you're in scope and act accordingly.

Quick test — you're likely covered if you can answer "yes" to any of these:

• Do you employ people in Illinois?
• Does your applicant-tracking system rank, score, or match candidates?
• Do you use a video-interview or assessment tool that evaluates applicants?
• Does anyone on your team use a generative-AI assistant to screen résumés or summarize candidate notes?
• Do you use AI in performance management, scheduling, or promotion decisions?

If you answered "yes" to even one, the law is your problem to manage.

What counts as an "AI tool" under HB 3773?

This is where most companies underestimate their exposure. The law defines AI broadly — it isn't limited to obvious "AI products." In practice, the systems that commonly trigger obligations include:

• Applicant tracking systems with matching, ranking, or scoring features
• Video interview platforms that assess or score candidates
• Résumé-screening and sourcing tools, including AI features inside LinkedIn Recruiter
• Generative-AI assistants (ChatGPT, Microsoft Copilot, Gemini) when used to screen, summarize, or evaluate candidates or employees
• Assessment and skills-testing platforms that use algorithms to rate applicants
• Performance-management and scheduling tools with predictive or automated features

The common trap: companies inventory their "AI vendors" and stop there — missing the AI features quietly added to tools they already owned, and the generative-AI use happening informally across the HR team.

The 4 most common HB 3773 compliance gaps right now

Gap 1 — No complete AI inventory. Companies can't comply with a law they can't map. Most have never documented everywhere AI touches an employment decision, so every downstream step is built on sand.

Gap 2 — Missing or generic notices. Either no candidate/employee notice exists, or a generic one was pasted in without matching how AI is actually used.

Gap 3 — A policy memo that was never implemented. Employment counsel delivered a memo; nobody turned it into an operational policy, a workflow, or a file.

Gap 4 — No vendor due diligence file. The company relies on its HR-tech vendors but has never documented whether those vendors are themselves compliant — leaving a hole exactly where a plaintiff would look.

What does an HB 3773 demand letter look like?

Because HB 3773 carries a private right of action, you don't have to wait for a state agency to act. A plaintiff's employment attorney can initiate a claim directly. The pattern typically opens with a demand letter — alleging that an AI tool produced a discriminatory outcome or that required notice wasn't given, and requesting that the company preserve and produce its documentation: the AI systems in use, the notices provided, the policy in place, and the diligence performed.

The companies that handle these well are the ones that can respond with a clean, dated file. The companies that struggle are the ones improvising a response after the letter arrives.

What are the penalties and damages?

Because the obligations sit within the Illinois Human Rights Act, claims proceed through the IHRA framework — which can mean administrative complaints through the Illinois Department of Human Rights, proceedings before the Human Rights Commission, and, given the private right of action, civil litigation. Exposure can include damages, attorneys' fees, and the substantial cost and disruption of defending a claim — to say nothing of the reputational hit.

How to get compliant — and prove it

Compliance isn't a single document. It's a file: an inventory, notices, a policy, a vendor-diligence record, training, and the dated evidence that ties it together. Built in the right order — inventory first, everything else on top — it becomes the thing you'd actually hand over if anyone ever asks.
