Major Timeline Changes for EU AI Act Implementation

The Council of the European Union has adopted significant amendments to the EU AI Act timeline as part of the “Omnibus VII” simplification package, providing extended deadlines for key compliance requirements that will impact AI companies across Ireland and the EU.

On March 13, 2026, the Council agreed to postpone the deadline for establishing AI regulatory sandboxes from August 2, 2026, to December 2, 2027. This 16-month extension affects the mandatory requirement for member states to establish at least one operational AI regulatory sandbox at national level.

High-Risk AI Systems Get Extended Compliance Window

Perhaps most significantly for AI developers, the Council position introduces staggered deadlines for high-risk AI systems:

  • December 2, 2027 for standalone high-risk AI systems
  • August 2, 2028 for high-risk AI systems built into products

These extensions represent delays of up to 16 months from the original timeline, providing breathing room for companies developing AI systems classified under Annex III of the AI Act.

New Prohibitions and Enforcement Challenges

The Council mandate adds new prohibited AI practices, specifically targeting “the generation of non-consensual sexual and intimate content or child sexual abuse material.” This addition reflects growing concerns about deepfake abuse and AI-generated harmful content.

However, enforcement remains a challenge. As of March 2026, only eight of 27 EU member states have established single contact points for AI Act enforcement, highlighting implementation gaps across the bloc.

What This Means for Irish AI Companies

For Irish AI developers and companies operating in the EU market, these delays provide additional time to ensure compliance with high-risk AI system requirements. However, it’s crucial to note that the current AI Act remains fully operative until the Digital Omnibus is officially adopted.

Still Uncertain: Final Legislative Timeline

The Council’s position is a negotiating mandate for upcoming trialogues with the European Parliament and Commission. A key committee vote was scheduled for March 18, 2026, but final adoption isn’t expected before mid-2026 at the earliest.

Bottom line: While these extensions offer compliance breathing room, AI companies should continue preparing for the original deadlines until the amendments are officially adopted.
