EU AI Act compliance timeline for 2026: what applies and what comes next

Overview

A date-by-date checklist separating rules already in force, requirements applying in 2026, and high-risk transition dates that organizations must keep under review.

What to review

1. Map whether you are a provider, deployer, importer, distributor, product manufacturer, or GPAI provider—and whether EU market or output connections bring you into scope.
2. Document prohibited-practice screening and AI literacy measures, which have applied since 2 February 2025.
3. For GPAI models, check the obligations applicable since 2 August 2025 and the separate transition for models placed on the market earlier.
4. Prepare for Article 50 transparency duties applying from 2 August 2026, including user notice and machine-readable marking where relevant.
5. Classify potentially high-risk systems, assign an owner, and monitor the Commission’s current implementation timetable and any final amending text.
6. Maintain an evidence register for inventory, classification, training, documentation, human oversight, incidents, vendors, and periodic review.

What to do next

Treat the timeline as a living compliance register, not a one-time memo. Record the legal basis for each classification and distinguish enacted requirements from proposals, political agreements, guidance, codes, and voluntary standards.
