Slow our EU AI Act prep now the deadline's moved to 2027?

While high-risk obligations defer to December 2027, Article 50 transparency duties and their EUR 15 million fines remain fixed for August 2026, catching systems regardless of risk tier. Failing to re-inventory and mark existing AI by December 2026 exposes your organization to immediate enforcement.

· Counsel verdict · AIssential

The question

The EU AI Act's high-risk deployer obligations (Article 26) look set to move from August 2026 to December 2027, but the deferral is not yet formally enacted and the transparency obligations still apply from August 2, 2026. Do we slow our compliance program to the new timeline, hold the original schedule to stay safe, or take a middle path?

Counsel's position

Adopt a middle path: prioritize immediate transparency and marking obligations, while strategically pacing high-risk compliance to the likely deferred timeline.

Verdict

Article 50 transparency and enforcement powers remain fixed for August 2026

The Digital Omnibus delays high-risk obligations but leaves transparency duties and their associated EUR 15 million or 3% turnover fines on the original timeline.

Article 50 transparency duties attach to system behavior rather than risk tier

Systems previously excluded from high-risk inventories—like support chatbots, voice agents, and AI note-takers—are subject to immediate transparency requirements.

Machine-readable marking transition for existing AI systems ends December 2026

While high-risk obligations are delayed, the enforcement machinery for general-purpose AI and transparency requirements is now operational.

The Digital Omnibus defers Annex III high-risk obligations by 16 months

The delay is intended to allow harmonized standards to be completed, but it does not pause enforcement for transparency or general-purpose AI rules.

High-risk AI provisions are product safety obligations that resist retrofitting

The extended deadline to December 2027 provides necessary time to build detailed technical documentation and conformity assessments into the development lifecycle.
