When does the EU AI Act come into force in Ireland?

Key dates for EU AI Act obligations

The EU AI Act has a phased implementation timeline. The prohibitions on unacceptable AI practices — social scoring, subliminal manipulation, real-time biometric surveillance in public spaces — came into force in February 2025. Organisations using any of these practices should have stopped. Obligations around general-purpose AI models (the foundation models that underpin many AI tools) apply from August 2025. The bulk of the Act's requirements — those applying to high-risk AI systems, transparency obligations for limited-risk AI, and the full enforcement regime — apply from August 2026. From that date, there is no grace period, no transition window, and no staged enforcement. Organisations that are not compliant from August 2026 are exposed to the Act's full penalty regime from day one.

Ireland's domestic legislation — the Regulation of Artificial Intelligence Bill 2026

The EU AI Act is directly applicable EU law, meaning it does not require separate transposition into Irish law. However, Ireland's Regulation of Artificial Intelligence Bill 2026 creates the domestic enforcement architecture that the Act requires. Published in February 2026, the Bill designates 15 National Competent Authorities along existing sectoral lines — the Central Bank for financial services, the DPC for personal data processing, the HPRA for medical devices, and so on. It establishes the AI Office of Ireland as a new statutory body that must be operational by 1 August 2026. It grants investigation and enforcement powers including unannounced inspections, information requests, and the ability to impose the Act's penalty tiers. For Irish organisations, the Bill makes the abstract threat of EU AI Act enforcement concrete and local — it is not a Brussels regulator making periodic interventions, but domestic regulators with established supervisory relationships.
