EU AI Act High-Risk System Violations

Last updated: 2026-06-20 — ComplianceStack Editorial Team

EU AI Act high-risk system violations carry the maximum penalties in the regulation — up to EUR 30M or 6% of global annual turnover (whichever is higher) for high-risk AI violations under Article 71. High-risk AI systems are defined in Annex III of the Regulation and include AI used in employment decisions, credit scoring, biometric identification, critical infrastructure management, and access to essential services. The EU AI Office (Article 88) enforces these provisions from August 2, 2026 for previously deployed systems, with new high-risk systems requiring conformity assessment before market entry.

Regulatory Authority: Regulation (EU) 2024/1689 (EU AI Act), Article 71; Annex III (high-risk AI systems); Articles 9-15 (high-risk obligations); Article 5 (prohibited practices); EU AI Office establishment, Article 88

Penalty Tier Breakdown

High-Risk AI System Violations (Art. 71)

EUR 30M or 6% global turnover

Annual max: Whichever is greater

Violations of obligations for high-risk AI systems under Annex III — including risk management (Art. 9), data governance (Art. 10), technical documentation (Art. 11), transparency (Art. 13), human oversight (Art. 14), accuracy/robustness (Art. 15), and conformity assessment failure.

Example: Employer deploys AI hiring tool that systematically scores female candidates lower without disclosed criteria — EU AI Office investigation finds technical documentation and oversight gaps.

Prohibited Practice (Art. 5) Violations

EUR 35M or 7% global turnover

Annual max: Whichever is higher

Deploying AI systems that manipulate behavior through subliminal techniques, exploit vulnerabilities, enable social scoring by public authorities, or use real-time remote biometric identification in public spaces for law enforcement (with limited exceptions).

Example: Government agency deploys facial recognition system for real-time crowd monitoring at public protests without legal authorization.

Non-Cooperation with AI Office Investigation

EUR 5M or 3% turnover

Annual max: Per day of continued non-compliance

Failure to provide information to the EU AI Office or national competent authority upon request, or failure to remedy an infringement within a specified period.

Example: Company continues operating a flagged AI system after the AI Office issues a corrective action request.

How Penalties Are Calculated

Penalties calculated on global annual turnover, not EU revenue. The higher of the fixed amount (EUR 30M/35M) or the percentage of global turnover applies. Fines reduced for small enterprises per Article 71(6). National authorities may impose additional fines below EU level thresholds.

Frequently Asked Questions

Does the EU AI Act apply to US companies?

Yes — if the AI system is placed on the market or put into service in the EU, or if its outputs are used in the EU. This includes SaaS products used by EU employees, AI-powered hiring tools for EU-based subsidiaries, or credit scoring services offered to EU consumers. US companies with EU operations or EU customers must comply.

What is a conformity assessment and how does it work for high-risk AI?

A conformity assessment is an independent technical evaluation verifying that the high-risk AI system meets EU AI Act requirements. For most high-risk systems, a notified body must conduct the assessment. Self-assessment is allowed only for certain Annex III categories. The assessment produces technical documentation that must be kept current and available to authorities for 10 years.
