Use our EU AI Act compliance 2025 checklist, risk-category comparison table, and tool recommendations to get audit-ready.
What Is the EU AI Act and Why It Matters in 2025
The EU AI Act is the world’s first comprehensive AI law. It introduces a risk-based framework for developing, placing on the market, and using AI systems in the EU. In 2025, core obligations begin phasing in—especially transparency for certain uses and duties for providers of general-purpose AI (GPAI).
Key goals and scope
- Protect fundamental rights and safety while fostering innovation.
- Apply proportionate, risk-based controls: prohibited, high-risk, limited-risk, and minimal-risk AI.
- Cover providers, deployers, importers, distributors, and authorized representatives of AI systems in the EU market.
Who is in scope: providers and deployers
- Providers: Organizations that develop an AI system or have it developed to place on the market or put into service under their name or trademark.
- Deployers: Organizations that use an AI system under their authority.
- Others: Importers, distributors, and EU reps also have distinct obligations.
EU AI Act Compliance 2025 Deadlines and Timeline
While the EU AI Act entered into force in 2024, requirements phase in through 2025 and 2026. Companies should prioritize 2025 deliverables to avoid enforcement risk. Always verify precise dates on official EU sources listed below, as guidance continues to evolve.
- Late 2024: Bans on certain prohibited AI practices begin to apply.
- 2025 (staggered): Transparency obligations for limited-risk uses and duties for GPAI providers start to bite; codes of practice and technical standards progress.
- 2026: The bulk of high-risk AI obligations (e.g., CE marking, conformity assessment) become mandatory.
| Phase | Area | What to do in 2025 |
|---|---|---|
| Prohibitions | Unacceptable risk AI | Confirm you don’t use banned practices; document rationale and evidence. |
| Transparency | Limited-risk AI | Implement user disclosure when interacting with AI, deepfake labeling, and data provenance where required. |
| GPAI | General-purpose AI | Publish technical documentation, training data summaries, model/system cards, risk mitigation, and usage policies. |
| High-risk prep | High-risk AI pipeline | Stand up Risk Management System (RMS), Data & Data Governance, and Quality Management System (QMS) to be ready for 2026. |
Risk Categories Explained
EU AI Act compliance 2025 efforts center on knowing your risk category and applying the right controls. Use the following breakdown to classify systems.
Prohibited practices (unacceptable risk)
- AI that manipulates behavior causing significant harm, or exploits vulnerabilities of specific groups.
- Certain real-time remote biometric identification for law enforcement in public spaces (with narrow exceptions).
- Social scoring by public authorities that leads to detrimental or unfair treatment.
High-risk AI systems
AI used in safety-critical or rights-critical contexts (e.g., employment, education, credit scoring, medical devices, critical infrastructure). High-risk requires a full conformity assessment, CE marking, RMS, QMS, technical documentation, human oversight, and post-market monitoring.
GPAI and foundation models
General-purpose AI that can be integrated into many downstream uses faces documentation and transparency duties. Some models with systemic risk may face additional obligations. EU AI Act compliance 2025 for GPAI providers includes model cards/system cards, data summaries, and risk mitigation measures.
Limited risk (transparency duties)
- Disclose that users are interacting with AI.
- Label deepfakes and AI-generated content as required.
- Provide clear instructions for safe use and limitations.
| Category | Examples | Key 2025 Actions |
|---|---|---|
| Prohibited | Social scoring, harmful manipulation | Eliminate or redesign; document controls; legal review. |
| High-risk | Recruiting, credit scoring, medical devices | Stand up RMS/QMS, gap analysis vs. standards, supplier due diligence. |
| GPAI | Foundation models, multipurpose LLMs | Publish technical docs, training data summaries, usage policies; set up model governance. |
| Limited risk | Chatbots, content generation | Add user disclosures, deepfake labels, safe-use guidance, logging. |

FAQs
Does the EU AI Act apply to non-EU companies?
Yes. If you place AI on the EU market or your AI outputs are used in the EU, the Act can apply, regardless of where you are established.
What are the penalties for non-compliance?
Administrative fines can be significant and scale by violation type (e.g., prohibited practices vs. documentation failures). Check the legal text for current thresholds.
How does the AI Act relate to GDPR?
They are complementary. GDPR governs personal data processing; the AI Act governs AI system safety, transparency, and risk. Many projects must comply with both.
Are open-source models covered?
Open-source availability does not automatically exempt obligations. Duties depend on your role, use, and risk. Review GPAI and high-risk requirements carefully.
What if we only use vendor AI?
Deployers still have duties: transparency, monitoring, safe use, and vendor due diligence. Contract for documentation and assurances from providers.
Do SMEs get any relief?
The Act encourages regulatory sandboxes and support. While obligations remain, guidance aims to reduce disproportionate burden on SMEs.
What documentation is expected in 2025?
Focus on model/system cards, training data summaries (where applicable), intended purpose, performance metrics, user instructions, and risk mitigations.
How do we prepare for high-risk conformity assessment?
Build an RMS/QMS, perform gap analysis against emerging harmonized standards, run evaluations, and start collecting evidence in structured templates.
