EU AI Act

The EU AI Act applies in phases, not on one date.

Different obligations switch on at different times (Article 113). Here is the full schedule, with the deadlines the Digital Omnibus changed clearly marked. As of September 2026, everything up to August 2026 is already in effect; the next milestones, new prohibitions in December 2026 and the deferred high-risk deadlines, are still ahead.

Transitional rules (easy to miss)

GPAI models already on the market

General-purpose AI models placed on the market before 2 August 2025 have until 2 August 2027 to come into compliance.

Art. 111(3)

High-risk systems already in use

High-risk systems placed on the market before their applicability date are generally caught only if they undergo a significant change in design after it.

Art. 111(2)

Dates rest on the amended Act

The high-risk deadlines above reflect the Digital Omnibus deferral. Confirm the current position with counsel before acting on a specific date.

What this means for you

Do not treat the AI Act as a single deadline. A company using an AI hiring tool already has AI-literacy and prohibited-practice duties live today, faces the full Annex III high-risk set from December 2027, and, if that tool is also a safety component of a regulated product, a further Annex I deadline in August 2028. The practical question is not “when does the Act apply” in the abstract, but which of these dates applies to your specific systems and role.
