EU AI Act Penalties
The EU AI Act enforces its obligations, including the Article 50 transparency and content-marking requirements, through tiered administrative fines set out in Article 99. Non-compliance with most provider and deployer obligations — including Article 50 — can draw fines of up to €15,000,000 or 3% of worldwide annual turnover, whichever is higher; other violation categories carry different maximums. This page summarizes the penalty structure and enforcement timeline; it is general information, not legal advice.
The three penalty tiers
Article 99 sets three tiers of maximum administrative fines. Violating the prohibited AI practices in Article 5 (such as certain manipulative or biometric-categorization uses) can draw fines of up to €35,000,000 or 7% of worldwide annual turnover, whichever is higher. Non-compliance with most other obligations for providers and deployers — including the Article 50 transparency and content-marking duties — falls into a middle tier of up to €15,000,000 or 3% of turnover; supplying incorrect, incomplete, or misleading information to regulators sits in a lower tier, up to €7,500,000 or 1% of turnover. For SMEs and startups, the lower of the percentage or the flat amount applies rather than the higher.
Enforcement timeline
Article 50's transparency obligations become legally binding and enforceable on 2 August 2026, with a transitional period until 2 December 2026 for AI systems already placed on the market beforehand. A separate 2026 legislative package — the Digital Omnibus on AI — postponed compliance deadlines for high-risk AI systems under Annexes I and III of the Act, but it left the Article 50 transparency deadline untouched; 2 August 2026 still applies to AI-generated content marking regardless of an AI system's risk classification.

Actual fines depend on the specifics of the violation and the enforcing authority's discretion.
When do EU AI Act penalties for Article 50 start applying?
Article 50 becomes binding and enforceable on 2 August 2026. Systems already on the market before that date get a transitional period until 2 December 2026 to come into compliance.
Does using a provenance tool like Certivu guarantee EU AI Act compliance?
No. Certivu provides cryptographically verifiable, machine-readable provenance that can support the technical marking and detectability goals behind Article 50, but overall compliance depends on your specific role, use case, and other obligations under the Act.
