When do state AI regulations take effect?

Last verified: May 31, 2026

Answer

Effective dates vary: Illinois HB-3773 took effect January 2025, California SB-942 applies from January 2026, Colorado's AI Act (SB 26-189, which repealed and reenacted SB 24-205) was signed May 14, 2026 and formally takes effect August 12, 2026, but its compliance obligations — for both deployers and developers — begin January 1, 2027, and Connecticut SB-1103 (state agencies only) took effect July 1, 2023. Note: the prior Colorado effective date of February 2026 or June 30, 2026 is no longer applicable — SB 26-189 was signed May 14, 2026; the statute formally takes effect August 12, 2026, but the operative compliance date for businesses is January 1, 2027.

Applicable Regulations

HB-3773

Illinois Human Rights Act AI Amendment (Public Act 103-0804)

enacted

Amends the Illinois Human Rights Act (775 ILCS 5/) to prohibit employers from using artificial intelligence that subjects employees or applicants to discrimination based on protected classes, and from using zip codes as a proxy for protected classes. Requires employers to notify employees when AI is used in recruitment, hiring, promotion, discharge, discipline, or other terms and conditions of employment. Defines "artificial intelligence" and "generative artificial intelligence" for purposes of the Act.

Key Requirements

AI Discrimination Prohibition Cannot use AI that has the effect of subjecting employees to discrimination on the basis of protected classes identified under the Illinois Human Rights Act
Zip Code Proxy Ban Cannot use zip codes as a proxy for protected classes under the Illinois Human Rights Act
Employee Notice of AI Use Must provide notice to an employee that the employer is using AI for recruitment, hiring, promotion, discharge, discipline, or other employment-related decisions
Effective: 2026-01-01 Penalties: Enforced through the Illinois Human Rights Act framework by the Illinois Department of Human Rights (IDHR); remedies follow IHRA procedures (injunctive relief, damages, attorney's fees) rather than a specific monetary penalty schedule in the amendment itself.
SB-942

California AI Transparency Act

enacted

Requires providers of large-scale generative AI systems (1 million+ monthly users) to make AI-generated content detectable through free public detection tools and embedded technical watermarks in image, video, and audio output. Signed September 19, 2024.

Key Requirements

Free AI Detection Tool Offer a free, publicly accessible tool allowing anyone to assess whether image, video, or audio content was created or altered by the provider's generative AI system
Manifest Disclosure Give users the option to attach a clear, conspicuous, human-readable disclosure on AI-generated content
Latent Technical Disclosure Embed technical metadata (provider name, system version, creation date, unique identifier) in AI-generated content, detectable by the provider's tool
Third-Party Licensee Enforcement Revoke licenses within 96 hours if a licensee disables disclosure capabilities
Effective: 2026-01-01 Penalties: Civil penalties of $5,000 per violation, each day constituting a separate violation.
SB-26-189

Colorado AI Act — Automated Decision-Making Technology (SB 26-189, repeal & reenactment of SB 24-205)

enacted

On 2026-05-14 Governor Polis signed SB 26-189, which repeals and reenacts the Colorado AI Act (originally SB 24-205). The new law abandons the risk-management / annual-impact-assessment model and replaces it with a disclosure-and-notice framework governing "automated decision-making technology" (ADMT) that makes or substantially influences "consequential decisions" (education, employment, housing, financial services, insurance, healthcare, government services). The statute formally takes effect 2026-08-12 (no safety clause), but all substantive compliance obligations — for both deployers and developers — begin 2027-01-01, which is the operative date for regulated businesses; the Attorney General's implementing rules are also due by 2027-01-01. The AG has stated he will not enforce until the mandatory rulemaking process concludes.

Key Requirements

Interaction Notice Deployers must give clear notice at the point of interaction when a consumer interacts with an automated decision-making technology (ADMT)
Adverse-Outcome Disclosure Provide a plain-language explanation within 30 days of an adverse consequential decision made or substantially influenced by an ADMT
Data Correction Right Allow consumers to request correction of factually incorrect personal data used by the ADMT
Meaningful Human Review Provide meaningful human review and reconsideration after an adverse consequential decision
Developer Documentation Developers must supply technical documentation (intended uses, known harmful uses, training-data categories, known limitations and risks, and instructions enabling meaningful human review), notify deployers of material updates, and retain compliance records for 3+ years. Like all duties under the act, these obligations begin 2027-01-01
Effective: 2027-01-01 Penalties: Enforced exclusively by the Colorado Attorney General; violations are treated as deceptive trade practices under the Colorado Consumer Protection Act. Before enforcement the AG must give 60 days' written notice and an opportunity to cure; this cure right sunsets 2030-01-01, after which enforcement may be immediate. The AG has stated no enforcement will occur until the mandatory rulemaking process concludes.
SB-1103

An Act Concerning Artificial Intelligence, Automated Decision-Making and Personal Data Privacy (Public Act 23-16)

enacted

Public Act 23-16 — the enacted form of Connecticut SB-1103 (2023 session). Signed by Governor Ned Lamont on June 7, 2023, making Connecticut among the first states to impose oversight on state agency use of AI. Government-only scope: does NOT directly regulate private-sector AI. Requires state agencies to complete impact assessments before deploying AI systems, publish a public AI inventory, and submit annual reports to the joint standing consumer-protection committee. Sections 1–3 effective July 1, 2023; Section 4 effective October 1, 2023; Section 5 effective upon passage.

Key Requirements

State Agency AI Impact Assessments State agencies may not employ AI systems that have not undergone impact assessments or that result in unlawful discrimination or disparate impact against specified individuals or groups
Public AI Inventory All inventory reports detailing AI systems used by state agencies and the Judicial Department must be publicly accessible online, with the Department of Administrative Services making its inventories available on the state's open data site
Annual Consumer-Protection Report Annual report to the joint standing committee on consumer protection, due February 15 beginning 2025 and annually thereafter
Effective: 2023-07-01 Penalties: Oversight and enforcement through legislative reporting requirements. Agencies failing to comply face ongoing reporting obligations to the Connecticut General Assembly.

  • Which states have enacted AI laws? As of early 2026, Colorado, Illinois, California, Connecticut, Minnesota, Texas, New York, Utah, Tennessee, Virginia, and Maryland have enacted AI-related legislation with varying scope from hiring-specific to comprehensive frameworks.
  • Which states actively regulate AI in employment as of 2026? Illinois and Colorado have the most prescriptive AI employment regimes as of 2026. Minnesota can reach employment profiling through privacy and data-protection-assessment rules. Texas should be monitored for TRAIGA prohibited practices, especially intentional discrimination and biometric identification, but HB-2060 is a state-agency AI advisory and inventory law, not a private-employer hiring disclosure rule. Connecticut's enacted AI law is government-only; private employers should monitor successor bills and generally applicable employment, privacy, and civil-rights law.
