The EU AI Act entered into force on 1 August 2024 and applies in stages. In 2026 the Digital Omnibus on AI, adopted as Regulation (EU) 2026/1744 and in force since 27 July 2026, moved the main high-risk deadlines. Many companies now ask the same question: what do we have to do today, and what can be planned for later? Here is the current timeline.
The timeline at a glance
| Date | What applies |
|---|---|
| 2 February 2025 | Prohibited AI practices (Article 5) and the first general provisions. |
| 2 August 2025 | Obligations for providers of general-purpose AI models, governance and penalties. |
| 2 August 2026 | Transparency obligations of Article 50, for example telling people they are interacting with an AI system. |
| 2 December 2026 | Marking of AI-generated content (Article 50(2)) and two new prohibitions added by the Omnibus. |
| 2 December 2027 | Stand-alone high-risk AI systems listed in Annex III, such as recruitment, credit scoring, education and critical infrastructure (previously 2 August 2026). |
| 2 August 2028 | High-risk AI embedded in products regulated under Annex I, such as machinery and medical devices (previously 2 August 2027). |

What the Digital Omnibus changed, and what it did not
The Omnibus postponed the high-risk obligations because harmonised standards and national authorities were not ready. It did not remove them. The requirements for high-risk systems are the same; only the date moved. Transparency duties and the prohibitions were not postponed.
What to do now
- Build an AI inventory. List every AI system you develop or use, including AI features inside third-party software.
- Classify each system. Prohibited, high-risk (Annex III or Annex I), transparency obligations only, or minimal risk.
- Close transparency gaps. Chatbots and generated content already have disclosure duties.
- Start high-risk work early. Risk management (Article 9), data governance, technical documentation, logging, human oversight and accuracy, robustness and cybersecurity (Article 15) take months to put in place.
- Test security and robustness. Adversarial testing such as LLM security testing gives you evidence for Article 15.
- Consider a management system. ISO/IEC 42001 gives AI governance a structure auditors recognise.
Penalties
Fines for the most serious breaches, the prohibited practices, can reach EUR 35 million or 7% of worldwide annual turnover, whichever is higher. Lower ceilings apply to other obligations.
Use the extra time well
December 2027 sounds far away, but conformity work for a high-risk system involves several teams and many documents. Companies that use the extra time to build governance and testing into their development process will be ready without a last-minute rush.
