What Happens If You Don't Comply with the EU AI Act?

Fines of up to €35M. Market withdrawal orders. Civil liability. Reputational damage. Here is what the consequences actually look like — and how enforcement will realistically work.

The penalty tiers

The EU AI Act has three levels of administrative fines, structured similarly to GDPR:

Tier 1 — Maximum: €35M or 7% of global annual revenue (whichever is higher)
For: Violating the prohibited practices (Article 5) — deploying banned AI applications like social scoring or real-time biometric surveillance
Tier 2 — High: €15M or 3% of global annual revenue
For: Non-compliance with requirements for high-risk AI, obligations for transparency, or obligations for general-purpose AI models
Tier 3 — Baseline: €7.5M or 1.5% of global annual revenue
For: Providing incorrect, incomplete or misleading information to national authorities or notified bodies

For SMEs and startups, the fines are proportionally capped. The thresholds are designed so that a startup with €1M in revenue does not face the same absolute fine as a company with €10B. But "proportional" still means 7% of revenue for the most serious violations — for a €5M ARR startup, that is €350,000.

How violations are discovered

Understanding how enforcement actually works is important. Regulators do not audit every company from day one. EU AI Act enforcement will realistically begin in a few ways:

Market surveillance sweeps

National Market Surveillance Authorities (MSAs) will conduct sector-by-sector audits. Expect the first sweeps to focus on the highest-risk sectors: hiring tools in major employment markets, credit scoring AI, healthcare diagnostic AI, and law enforcement-adjacent tools.

Complaints from individuals

Any person who believes an AI system violating the EU AI Act affected them can file a complaint with their national MSA. For hiring AI specifically, expect rejected candidates to file complaints when they believe they were unfairly screened out by an algorithm.

Competitor complaints

Competitors can report non-compliant AI systems to regulators. This is already common in GDPR enforcement. A compliant company may report a non-compliant competitor to level the playing field.

Media investigations

Investigative journalists have successfully triggered GDPR enforcement through public reporting. The same pattern will emerge with AI. An article showing that Company X's hiring AI discriminates against women can trigger immediate regulatory investigation.

Self-disclosure

Some violations will be self-reported — especially payment failures, which is required. When your AI system causes harm, the EU AI Act requires providers to notify the relevant national authority. Proactive disclosure typically results in lower fines.

What happens during an enforcement action

Based on the GDPR enforcement model (which the EU AI Act is designed similarly to):

  1. Investigation opened: You receive notice that the national MSA is investigating. You must cooperate and provide documentation.
  2. Request for information: You will be asked to provide your technical documentation, risk management records, conformity assessment, and logs.
  3. On-site inspection: The MSA may conduct an on-site inspection of your facilities and systems.
  4. Preliminary findings: The MSA issues preliminary findings and you have the right to respond.
  5. Decision: The MSA issues a decision with remediation requirements and potentially a fine.
  6. Remediation period: If you are ordered to fix the issue, you have a time period to do so. Failure to remediate can result in market withdrawal orders — banning you from operating in the EU.

This process typically takes 6–18 months for significant cases. GDPR investigations have sometimes taken several years. Do not expect overnight enforcement actions for most violations.

Consequences beyond the fine

The administrative fine is not always the worst outcome:

Who will actually be fined first

Regulatory resources are limited. Expect the early enforcement to focus on:

Startups and SMEs using off-the-shelf AI tools for low-risk purposes are unlikely to be targeted in the first wave of enforcement. However, high-risk AI users in any company size are at risk.

The cost of compliance vs. non-compliance

EU AI Act compliance for a mid-market company with high-risk AI typically costs:

Compare that to Tier 2 fines starting at €15M for serious violations. The math strongly favors compliance. Even for minimal risk AI with no real compliance obligation, a brief audit to confirm your classification is minimal risk (and document that conclusion) costs almost nothing.
