On 7 August 2025, the Bill on Personal Data Protection in Artificial Intelligence Systems (No. 4243-D-2025) was introduced in the Chamber of Deputies. The Bill aims to establish a legal regime applicable to the use of personal data of citizens by natural or legal persons that develop, operate, implement, or commercialise artificial intelligence (AI) systems, covering any personal data processing conducted within Argentine territory or targeting persons in Argentina, irrespective of the operator’s location. The Bill adopts definitions of personal data from Law No. 25.326 and designates the competent authority to be appointed by the National Executive Power pursuant to Law No. 26.939. The Bill includes transparency obligations requiring operators to disclose system purpose, logic, automation level, use of personal data, and to enable the exercise of data subject rights. It requires risk evaluations considering nature, scope, context, and mitigation measures, and classifies risks as low, medium, or high, with mandatory registration in the National Registry of Artificial Intelligence Systems for medium- and high-risk systems, including developer details, system description, impact assessment, and data protection policies. The authority is empowered to conduct audits, require documentation, and suspend systems posing serious risks, with sanctions ranging from warnings to suspension, prohibition of use, and fines proportionate to turnover, benefits, number of affected individuals, and intent or negligence. The Bill stipulates that the Executive must regulate it within 60 days of promulgation, existing systems must comply within 180 days, it enters into force 30 days after publication in the Official Gazette, and invites provincial and Buenos Aires City adherence
