EU AI Act vs Colorado AI Act (SB 24-205): Comparison for Companies Selling in Both
Colorado’s AI Act targets algorithmic discrimination in consequential decisions; the EU AI Act regulates AI as a product across four risk tiers. Scope, duties, deadlines and how one file can serve both.
Classify my system in 3 minutesThe bottom line
If you comply with the EU AI Act for a high-risk system, you have most of what Colorado requires (risk management, impact assessment, documentation to deployers, notices to consumers, adverse-decision explanations). The reverse is not true: Colorado compliance covers none of the EU product-safety steps and nothing outside consequential decisions. Build the EU file first and derive the Colorado deliverables from it.
Colorado’s Artificial Intelligence Act (SB 24-205) is the first comprehensive US state AI law. After a legislative delay, it applies from 30 June 2026. It targets one thing: algorithmic discrimination by “high-risk AI systems” that make or substantially influence consequential decisions about education, employment, financial services, essential government services, healthcare, housing, insurance or legal services.
That list will look familiar to anyone who has read Annex III of the EU AI Act, and the overlap is intentional. The difference is breadth: Colorado stops at discrimination and disclosure duties for developers and deployers, while the EU law adds prohibited practices, transparency for chatbots and synthetic content, general-purpose model rules and a full product-safety regime with conformity assessment and CE marking.

Where Colorado AI Act work counts toward the AI Act
- The Art. 9 risk management file and the Art. 27 fundamental rights impact assessment map directly onto Colorado’s risk management programme and impact assessment.
- Art. 13 instructions for use give deployers the information Colorado requires developers to provide (purpose, data summary, limitations, evaluation results).
- Art. 86 right to explanation and the human oversight override satisfy Colorado’s adverse-decision explanation and appeal duties.
- The Art. 50 “you are interacting with AI” notice is the same disclosure Colorado requires.
- Because ISO/IEC 42001 and NIST AI RMF give a Colorado presumption of reasonable care, an AI Act quality management system built on either does double duty.

What Colorado AI Act does not cover
- Colorado has no conformity assessment, CE marking or registration; the EU steps must be done in addition.
- Colorado does not regulate chatbots, recommenders or content generation beyond the interaction disclosure.
- Colorado has no prohibited-practice list; the EU Art. 5 review is still required.
- Colorado’s 90-day discrimination notice to the Attorney General has no EU equivalent, while the EU serious-incident reporting (Art. 73) has no Colorado equivalent.

FAQ
Frequently asked questions
We only sell in the US. Does the EU AI Act still matter?
Only if your system is placed on the EU market or its output is used in the EU. If you have no EU users or customers, the EU law does not apply, but Colorado, plus similar bills in other states, does.
Does the Colorado safe harbour mean ISO 42001 is enough there?
It creates a rebuttable presumption that you used reasonable care, which is one element of the developer and deployer duties. The disclosure, notice and impact-assessment duties still have to be performed.
Is a hiring tool high-risk under both laws?
Yes. Employment is a consequential-decision area in Colorado and Annex III(4) in the EU. In the EU it carries the full provider regime; in Colorado it carries the discrimination-focused duties.
