AI regulation deadline tracker
Compliance deadlines for AI regulation, each carrying its own verification state. Dates get amended and repealed after publication — this tracker shows you which ones have actually been checked.
| Regulation | Effective | Applies to | What it requires |
|---|---|---|---|
| CART Act — developer information-sharing obligations Connecticut · CT Public Act 26-15 (Substitute Senate Bill No. 5) Verified 2026-07-26 |
2026-10-01 | Developers who market or contract an AI system for employment use in Connecticut. | Supply deploying employers with the information they need to meet their own disclosure duties. A trade-secret carve-out applies from the same date. This is the CART Act date that actually falls in 2026 — and it is a developer duty, not an employer one. Tracked as its own entry so the two are never conflated. |
| CART Act — AEDT use is not a defense to a discrimination claim Connecticut · CT Public Act 26-15, amending Conn. Gen. Stat. § 46a-60 Verified 2026-07-26 |
2026-10-01 | Connecticut employers using automated employment-related decision technology, whether built in-house or bought from a vendor. | Use of an AEDT cannot be raised as a defense to a discriminatory employment practice complaint. A commission or court may still weigh evidence of anti-bias testing — its quality, efficacy, recency and scope, and what the employer did about the results. A liability rule rather than a policy clause, but it changes what a policy is worth: bias-testing and vendor-diligence records become the evidence that matters, since pointing at the vendor no longer works. |
| CART Act — WARN notice must disclose AI as a layoff cause Connecticut · CT Public Act 26-15 (Substitute Senate Bill No. 5) Verified 2026-07-26 |
2026-10-01 | Employers filing a plant-closing or mass-layoff notice with the Connecticut Department of Labor. | The WARN notice must state whether the layoffs relate to the employer's use of artificial intelligence or other technological change. The earliest of the Act's employer deadlines, and the one least likely to be on an employer's radar because it only bites during a reduction in force. Arrives a full year before the AEDT notice duty that most coverage leads with. |
| Colorado Automated Decision-Making Technology Act Colorado · Colorado SB 26-189 (repeals and reenacts the Colorado AI Act, SB 24-205) Verified 2026-07-26 |
2027-01-01 | Developers and deployers of automated decision-making technology that materially influences a consequential decision. | Consumer notice, an explanation when there is an adverse outcome, meaningful human review, and developer documentation. CORRECTED 2026-07-26 — an earlier draft cited SB 24-205 and described a duty of reasonable care plus mandatory impact assessments. That law never took effect: it was repealed and reenacted by SB 26-189, signed 2026-05-14. The duty of care, mandatory impact assessments and the risk-management-program requirement were REMOVED; what replaced them is a narrower transparency and human-review regime. This statute has now moved three times (2026-02-01 → 2026-06-30 → repealed → 2027-01-01), so re-check before relying on it. |
| Connecticut AI Responsibility and Transparency Act (CART Act) — employer AEDT duties Connecticut · CT Public Act 26-15 (Substitute Senate Bill No. 5) Verified 2026-07-26 |
2027-10-01 | Employers deploying automated employment-related decision technology (AEDT) in Connecticut. | Before an employment-related decision in which an AEDT is a substantial factor, written notice disclosing the use and purpose of the AEDT, its trade name, the categories and sources of personal data used, how that data is assessed, and employer contact information. A separate interaction disclosure applies when a person is dealing with automated technology. CORRECTED 2026-07-26 — an earlier draft of this entry dated the employer disclosure duty 2026-10-01, which is wrong. The Act splits its dates: 2026-10-01 starts DEVELOPER information-sharing obligations and the trade-secret carve-out; the employer-facing interaction disclosure and pre-decision notice duties begin 2027-10-01. Signed by Governor Lamont 2026-06-02. Developers may contractually assume the employer's disclosure duty, which makes vendor contracts the early compliance lever. |
This tracker is deliberately short. Entries are added only once the effective date has been checked against the enacted text — not assembled from secondary coverage.
Why this list is short on purpose
AI regulation is being written faster than it is being finalised, and the gap between "announced" and "in force" is where most compliance content goes wrong. Deadlines slip. Statutes get amended before they bite. At least one widely-reported state AI deadline was repealed and moved a full year after a great deal of guidance had already been published against the original date — including, briefly, on this site.
So the rule here is simple: a date appears on this page only when someone has read the current enacted text, and it carries the date that check happened. A short list you can trust is worth more than a comprehensive one you have to re-verify yourself.
What to do regardless of jurisdiction
Almost every AI regulation now in force or in progress asks for some combination of the same four things, and none of them depend on knowing your exact deadline:
Know what you are using. An inventory of AI tools in use, including the ones nobody approved. Most obligations attach to systems you must first be able to name.
Know what it decides. The obligations bite hardest where AI touches employment, credit, housing, insurance and healthcare. Ordinary productivity use is regulated far more lightly.
Tell people. Disclosure duties — to candidates, customers, or employees — are the most common single requirement across jurisdictions and the easiest to retrofit.
Write it down. A policy, an approval route, and evidence that staff acknowledged it. Documentation is what turns a defensible position into a provable one.
A policy covers the four things every AI regulation asks for
