Ireland

Legal Framework

Ireland applies the EU AI Act directly. Its Article 50 transparency duties have applied since 2 August 2026: providers must tell people when they are interacting with an AI system and mark generated content in a machine-readable way, and deployers must label deepfakes. Generative systems already on the market before 2 August 2026 have until 2 December 2026 to add marking, and new bans on AI systems that generate non-consensual sexual deepfakes or child sexual abuse material apply from the same date (Digital Omnibus on AI, Regulation (EU) 2026/1744). Rules for Annex III high-risk systems now apply from 2 December 2027. At EU level, the Commission said on 12 October 2026 that its AI Office has requested and received serious incident reports on recent loss-of-control incidents and will send further requests for information to the companies that developed the models involved. On 14 October 2026, Executive Vice-President Henna Virkkunen said the AI Office has started enforcing the AI Act's rules for general-purpose AI providers and has sent requests for information "addressing issues such as security, external evaluation and monitoring how models are used". None of these Commission statements addresses companies that deploy those models. In October 2026 the Official Journal cited EN 18286:2026, a quality management system standard, as the first harmonised standard supporting the AI Act; CEN-CENELEC says it gives providers of high-risk AI systems a route to a presumption of conformity with the Act's Article 17 quality management requirements. The Regulation of Artificial Intelligence Act 2026 (Act 31 of 2026), signed into law on 21 July 2026 and in operation since 31 July 2026, gives further effect to the AI Act and establishes the AI Office of Ireland (Oifig IS na hÉireann) as an independent statutory body. The AI Office coordinates AI Act implementation in Ireland, is the single point of contact for the European Commission, national sectoral regulators and the public, helps other competent authorities get technical expertise, and is developing Ireland's AI regulatory sandbox. Market surveillance authorities carry out AI Act investigations, with technical support from the AI Office. The Office began operating on 31 July 2026, has opened a Service Desk for queries and complaints, and its board first met in September 2026. Ireland hosts the European headquarters of most major US tech companies, and the Data Protection Commission (DPC) is the lead GDPR supervisor for many global tech firms because of their Irish establishment. IDA Ireland actively recruits technology companies with incentive packages. Ireland's common law system is familiar to US and UK companies.
