Hungary’s AI implementation law enters into force
Most provisions of Hungary’s Act LXXV of 2025, which sets out national procedures for enforcing the EU Artificial Intelligence Regulation, took effect on 1 December 2025. The law establishes domestic oversight structures, market-surveillance processes and sanctions mechanisms for AI systems used or placed on the Hungarian market.
Hungary’s Act LXXV of 2025, adopted to implement the European Union Artificial Intelligence Regulation, entered into force on 1 December 2025, thirty-one days after its promulgation. Two provisions, Section 3(2) and Section 10, will take effect later, on 2 August 2026. The law establishes how Hungary will conduct market-surveillance, notification and enforcement procedures for AI systems that are placed on the market, put into service or whose outputs are used within the country.
The Act outlines national processes for handling market-surveillance proceedings, including checks on providers, deployers, manufacturers, importers and authorised representatives. It also sets out how Hungary will apply Article 99 sanctions of the EU Regulation, extending these enforcement powers to third-country actors when AI outputs are used domestically. In addition, the law governs notification procedures initiated in Hungary under Article 28 of the EU Regulation.
To operationalise these responsibilities, the Act empowers the government to designate both an AI notifying authority and an AI market-surveillance authority, aligned with Articles 28 and 70 of the EU Regulation. It establishes a single point of contact for coordination, introduces special procedural rules for administrative cases and creates the Hungarian Artificial Intelligence Council, which will provide strategic guidance and facilitate cross-government cooperation on AI oversight.
The legislation also includes provisions for an AI regulatory test environment, intended to support controlled experimentation with AI systems under regulatory supervision. Certain market-surveillance tasks in the financial sector are assigned to Hungary’s central bank, pursuant to Article 74(6) of the EU Regulation.
With the Act now in effect, Hungary joins other EU member states in putting in place the national structures required for enforcing the bloc’s AI framework as it begins to apply across the Union.
