General requirements to tell customers, employees, or the public when AI is being used in decisions. Here is what Missouri businesses need to know in 2026.
Missouri has enacted No AI-specific law. No state-specific AI law. Federal laws apply. Missouri AG monitors AI-driven consumer protection violations under the Merchandising Practices Act.
State law does not replace federal law — you must comply with both. These federal rules apply to ai disclosure nationwide:
It depends on the thresholds written into the specific statute, and those are not comparable across laws — some key on employee count or revenue, others on user volume or on the kind of system you deploy. We do not publish a generic small-business exemption for Missouri, because stating one the statute does not contain would be worse than stating none. Read the primary source linked from our Missouri law page to confirm whether you are in scope.
The key deadline in Missouri is N/A. The law is still developing — monitor for final rules.
Missouri penalties for AI non-compliance: N/A. Who enforces, and how, varies by statute — check the primary source linked from our Missouri law page for the enforcement authority and process that actually applies to you.
Federal law does not currently preempt state AI law. Missouri's AI statutes apply independently of federal rules, and federal laws like ECOA, FCRA, and HIPAA apply alongside them — so you must comply with both.
Best practice: document all AI systems used, conduct an internal audit, implement required disclosures, and keep records for at least 3 years. For high-risk uses like ai disclosure, consider hiring an independent third-party auditor to validate compliance.
