The EU AI Act is the world’s first comprehensive AI regulation, fully in force in 2026. Non-compliance with high-risk AI requirements carries fines up to €30 million or 6% of global revenue. For any organization operating in or serving European markets, compliance is not optional. This guide explains risk tiers, high-risk obligations, and practical compliance steps.
Risk Classification System
Prohibited (banned): social scoring, real-time biometric identification in public spaces, subliminal behavioral manipulation. High-risk (conformity assessment required): hiring AI, lending AI, educational assessment, healthcare AI, law enforcement, border control, critical infrastructure. GPAI models: registration and technical documentation with EU AI Office. Minimal risk: most consumer AI applications with voluntary code of conduct.
EU AI Act compliance requirements for high-risk systems include: risk management system documenting foreseeable risk identification and mitigation; data governance practices ensuring training data quality and representativeness; technical documentation enabling regulatory review; logging requirements enabling audit trails of AI decisions; user transparency about AI involvement; human oversight mechanisms for consequential decisions; accuracy, robustness, and cybersecurity measures. The implementation timeline: prohibited AI bans effective 6 months after entry into force; GPAI provisions effective 12 months; high-risk requirements phased 24-36 months depending on sector. SMEs receive proportional treatment with national authority guidance. Non-compliance fines reach €30 million or 6% of worldwide annual turnover, whichever is higher — making compliance investment materially cheaper than enforcement risk for any organization with meaningful European revenue.
