EU AI Act Rules for SMEs and Startups

The Act applies according to role, system type, and use, not simply company size. A startup that provides a high-risk AI system can still have risk-management, data, documentation, quality, transparency, and conformity duties when the relevant rules apply. Size-specific provisions make some routes more proportionate; they are not a general exemption from the Regulation or from privacy, product-safety, and employment law. Article 62 requires Member States to provide SMEs, including startups with a Union registered office or branch, priority access to regulatory sandboxes when they meet eligibility and selection criteria. It also calls for tailored awareness and training, communication channels for questions, and support for SME participation in standards work. Conformity-assessment fees must take account of SME interests and be reduced proportionately to size, market size, and other relevant indicators. This is a targeted fee reduction, not a promise that every assessment is free. Sandbox access and fee relief depend on the applicable conditions. The 2026 Digital Omnibus added small mid-cap enterprises to selected support measures and simplified modalities. It allows qualifying SMEs, including startups, and SMCs to provide specified Annex IV technical documentation in simplified form using a Commission form, which notified bodies must accept for conformity assessment. Some Article 17 quality-management aspects may be implemented proportionately, but providers must still meet the level of protection and rigour required. For SMCs, the Omnibus also adjusts the applicable fine cap to the lower of the fixed amount or the turnover percentage in the specified provisions. These changes are specific, not across-the-board reductions. Companies should first determine whether they meet the EU SME or SMC definition, including linked and partner-enterprise rules. Then map which exact provisions offer relief, what evidence is required, and which underlying requirements remain. Keep the assessment current as staffing, turnover, ownership, and system use change.
