The EU AI Act Implementation Timeline
| Date | What Becomes Enforceable | Impact for US Companies |
|---|---|---|
| Aug 1, 2024 | AI Act enters into force | Preparation period begins |
| Feb 2, 2025 | Prohibited AI practices banned; general provisions active | Review AI systems against prohibited categories immediately |
| Aug 2, 2025 | General-purpose AI (GPAI) model rules apply; AI literacy (Art. 4) | GPAI providers must comply; all entities must address AI literacy |
| Aug 2, 2026 | Most remaining provisions including Annex III high-risk requirements, conformity assessment, transparency, database registration | Full compliance required for high-risk systems; key deadline for most US companies |
| Aug 2, 2027 | Article 6(1) — AI safety components in regulated products | Affects AI embedded in medical devices, vehicles, machinery, toys |
Prohibited AI practices (social scoring, subliminal manipulation, emotion recognition in workplaces/schools) have been banned since February 2, 2025. If you operate any of these systems with EU impact, you are already non-compliant. Article 4 AI literacy obligations have been active since August 2025.
What Happens on August 2, 2026
This is the date most US companies need to focus on. On August 2, 2026, the following become enforceable:
- Annex III high-risk system requirements — risk management, data governance, technical documentation, human oversight, accuracy and robustness standards
- Conformity assessment — systems must pass assessment and receive CE marking
- EU database registration — Article 71 registration mandatory before deployment
- Transparency obligations — AI-generated content labeling, chatbot disclosure requirements
- EU Authorized Representative — non-EU high-risk providers must have appointed their representative
- Post-market monitoring — surveillance systems must be operational
- AI regulatory sandboxes — each member state must have at least one operational
How Much Time Do You Have
As of today, you have approximately 3.5 months until the August 2, 2026 deadline. This is tight but workable if you start now.
A realistic compliance timeline for a US company with 2-5 high-risk AI systems:
- Weeks 1-2: AI system inventory and scope determination
- Weeks 3-4: Risk classification and gap analysis
- Weeks 5-8: Technical documentation preparation (Annex IV)
- Weeks 9-10: Risk management system implementation
- Weeks 11-12: Conformity assessment and EU database registration
- Weeks 13-14: EU Authorized Representative appointment and post-market monitoring setup
Companies that start compliance in the last 60 days before the deadline face emergency pricing, rushed documentation, and higher risk of gaps. Contact Lexara Advisory now to begin your compliance timeline with adequate preparation time.
