EU AI Act timeline: every deadline that matters

The Regulation has a staggered application timeline. Most teams underestimate how soon the next deadline arrives.

1 Aug 2024

Entry into force

Regulation (EU) 2024/1689 enters into force across the EU. The clock starts.

2 Feb 2025

Prohibitions apply

Article 5 (prohibited practices) and Article 4 (AI literacy) become binding. Six months after entry into force.

2 Aug 2025

Governance + GPAI obligations apply

Chapter III §4 (notification), Chapter V (GPAI), Chapter VII (governance), Chapter XII (penalties) become binding.

2 Aug 2026

Most obligations apply

The rest of the Regulation — including Annex III high-risk obligations — becomes binding. Two years after entry into force.

2 Aug 2027

Annex I (regulated-product) high-risk applies

AI systems that are safety components of products already regulated under Annex I get an extra year. Three years after entry into force.

What this means for your roadmap

If you have any system that could land in Annex III, you have until August 2026 — roughly 14 months from now — to be fully audit-ready. That window is shorter than most enterprise procurement cycles.
