days until EU AI Act Article 50 takes effect
Quick answer

The EU AI Act establishes three penalty tiers: EUR 35 million or 7% of turnover for prohibited practices, EUR 15 million or 3% for other violations including transparency, and EUR 7.5 million or 1.5% for supplying incorrect information. For SMEs, fines are capped at the lower of the percentage or fixed amount.

EU AI Act Penalties: Up to EUR 35 Million for Non-Compliance

What happened

Article 99 of the EU AI Act establishes one of the most significant penalty frameworks in EU technology regulation — potentially exceeding even GDPR fines for the most serious violations. With the first enforcement deadline (Article 5 prohibited practices) already past and Article 50 transparency obligations taking effect on August 2, 2026, understanding the penalty structure is now an operational necessity.

The three-tier penalty structure

Tier 1: Prohibited AI practices — the highest fines

Violations of Article 5 (prohibited AI practices) carry the most severe penalties:

Tier 2: Other obligations — where most organisations face risk

Non-compliance with most AI Act obligations falls under Tier 2:

Tier 3: Incorrect information

SME proportionality rule

For SMEs and startups, each fine is capped at the lower of the percentage or the fixed amount — not the higher. This means a startup with EUR 2 million turnover faces a maximum Tier 2 fine of EUR 60,000 (3% of EUR 2M), not EUR 15 million.

What to do now

  1. Classify your exposure. Map each AI system against the three tiers. Which systems could trigger Tier 1 (prohibited)? Which fall under Tier 2 (transparency, GPAI)?
  2. Prioritise by penalty severity. Address any potential Article 5 violations immediately — these carry the highest fines and are already enforceable
  3. Budget for compliance. The cost of compliance is orders of magnitude lower than the cost of a single penalty. Even the SME-capped minimum of 1.5-3% of turnover is significant
  4. Document everything. In an enforcement action, your documentation is your defence. If it is not documented, it cannot be demonstrated to a regulator
