The 2026 Digital Omnibus on AI extended two key AI Act deadlines and made targeted amendments. Annex III standalone systems move to 2 December 2027; Annex I embedded systems to 2 August 2028. Prohibited practices, GPAI rules, and transparency obligations are unchanged.
What the 2026 Digital Omnibus on AI changed
The Digital Omnibus on AI made two central changes to the EU AI Act application dates:
| Provision | Before omnibus | After omnibus |
|---|---|---|
| High-risk AI — Annex III (standalone) | 2 August 2026 | 2 December 2027 |
| High-risk AI — Annex I (embedded) | 2 August 2026 | 2 August 2028 |
Every other deadline was left unchanged. The omnibus did not create new obligations, remove existing ones, or introduce derogations or exemptions.
Why the Commission extended the deadlines
Three official reasons:
-
Standards not ready — Harmonised technical standards needed for conformity assessments under AI Act Art. 40 were not finalised by the original August 2026 deadline. Without these standards, conformity assessments could not be completed properly.
-
Enforcement infrastructure gap — Notified bodies needed designation and accreditation. National competent authorities required resources and guidelines. The EU AI Office needed operational capacity. An August 2026 deadline would have been unenforceable in practice.
-
Industry and SME readiness — Particularly for smaller providers in medtech, HR technology, and financial services, the parallel burden of AI Act, DORA (January 2025), and NIS2 (October 2024) compliance was cited as excessive.
What the omnibus does NOT do
The omnibus extension is commonly misread as reducing the regulatory burden. It does not:
- Remove any obligation
- Create an exemption for any sector or company size
- Reduce fines for non-compliance after the new deadlines
- Change the scope of what constitutes high-risk AI under Annex III or Annex I
- Affect GPAI rules, prohibited practice bans, or transparency obligations

The Digital Omnibus on AI is an EU legislative act adopted in mid-2026 that amended Regulation (EU) 2024/1689 (the AI Act). Its primary effect was extending two compliance deadlines — for Annex III standalone high-risk AI to 2 December 2027, and for Annex I embedded high-risk AI to 2 August 2028 — to allow time for harmonised standards and enforcement infrastructure to be established.
No. The omnibus is a temporal extension only. All obligations — conformity assessment, QMS, technical documentation, CE marking, EU database registration, fundamental rights impact assessments — remain identical. Only the deadlines shifted.
Prohibited practices (Art. 5, in force since 2 February 2025), GPAI rules (Chapter 5, in force since 2 August 2025), transparency for AI-generated content (Art. 50, since 2 August 2025), and regulatory sandbox establishment (Art. 57, since 2 August 2026) were all unchanged.
