EU AI Act Timeline — Key Dates and Deadlines 2024-2027

The EU AI Act (Regulation 2024/1689) applies in phases. Prohibited practices are already enforced since February 2, 2025. GPAI rules apply from August 2, 2025. The biggest deadline — high-risk AI system requirements — applies from August 2, 2026. Here is every date you need to know.

The Problem

The AI Act does not apply all at once. Different requirements kick in at different times over a 3-year period. Miss a deadline and you are non-compliant. But most summaries just mention "2026" without the specifics — which requirements, which date, which systems.

Countdown

The August 2, 2026 deadline for high-risk AI is approaching. If your AI system is classified as high-risk under Annex III, you need to have conformity assessment, risk management, documentation, and human oversight in place by that date.

FAQ

Is the AI Act already in force?

Yes. The AI Act entered into force on August 1, 2024. Prohibited practices apply since February 2, 2025. GPAI rules since August 2, 2025. The remaining provisions (high-risk systems) apply from August 2, 2026.

What is the most important deadline for most companies?

August 2, 2026 — when high-risk AI system obligations take full effect. If your AI system falls under Annex III (employment, credit scoring, biometrics, etc.), you must have conformity assessment, risk management, and all Article 6-49 requirements in place by this date.

Are there penalties before August 2026?

Yes. Prohibited practices (Article 5) are already enforceable since February 2025, with penalties up to 35 million EUR or 7% of global turnover. AI literacy (Article 4) and GPAI obligations (Articles 51-56) are also already applicable.

Do existing AI systems need to comply?

Yes. Article 111(2) provides that high-risk AI systems already on the market before August 2, 2026 must comply if they are significantly modified after that date. Systems placed on the market after August 2, 2026 must be fully compliant from day one.

What happens at the August 2027 deadline?

August 2, 2027 is when high-risk obligations apply to AI systems that are safety components of products covered by existing EU harmonisation legislation (Annex I) — medical devices, machinery, toys, lifts, radio equipment, etc. These get an extra year because they already have existing conformity assessment frameworks.

Can I start preparing now?

Yes, and you should. Classify your AI systems, identify which are high-risk, and begin implementing risk management systems, documentation, and human oversight. Use the Gibs API to classify systems programmatically and identify applicable obligations.

Does Gibs cover other regulations besides the AI Act?

Yes. Gibs currently covers the EU AI Act, DORA (Digital Operational Resilience Act), and GDPR. Cross-regulation queries are supported — ask how AI Act requirements interact with GDPR data protection obligations and get cited answers from both regulations. Additional regulations are planned.
