EU AI Act Annex III: high-risk AI systems guide for SMEs

Annex III lists eight categories of AI use-cases subject to the EU AI Act's most demanding obligations. If your business uses AI in any of these areas, the full Chapter III deployer duties — including fundamental rights impact assessments and EU AI database registration — apply from 2 December 2027.

Last regulatory review: 14 August 2026 · Regulation (EU) 2024/1689 as amended by Regulation (EU) 2026/1744

What is Annex III?

Annex III of Regulation (EU) 2024/1689 lists the AI use-cases that attract the "high-risk" classification under Article 6. AI systems used for these purposes must comply with Chapter III of the Act — a comprehensive set of requirements covering risk management, data governance, transparency, human oversight, and accuracy. For deployers (businesses using rather than developing AI), the key obligation is Article 26.

Deadline amended. The original application date for Chapter III obligations was 2 August 2026. Regulation (EU) 2026/1744 amended this to 2 December 2027. Businesses using Annex III AI have more time to prepare — but preparation should start now.

The eight Annex III high-risk AI categories

Each category includes an SME relevance indicator to help you prioritise.

SME relevance:

Biometric identification and categorisation

1

Low — most SMEs do not operate biometric identification systems

AI systems used for real-time or post-event remote biometric identification of natural persons in publicly accessible spaces. Includes biometric systems for authentication if used for consequential identity verification purposes at scale.

Critical infrastructure management

2

Low — applies to utility, transport, and infrastructure operators

AI intended as safety components in the management and operation of critical digital infrastructure, road traffic, and the supply of water, gas, heating, or electricity.

Education and vocational training

3

Medium — applies to training providers using AI assessment

AI used to determine access to educational and vocational training institutions, to evaluate or grade students, to detect prohibited behaviour during assessments, and to recommend the level of education appropriate for an individual.

Employment, worker management, and self-employment

4

High — widely used in SME HR and recruitment

AI used for recruitment or selection of natural persons (including CV screening, job targeting, and interview analysis), for performance evaluation, promotion decisions, task allocation, and monitoring of behaviour and performance in employment contexts. This is the most commonly relevant category for SMEs.

Essential private and public services

5

Medium — applies to financial services, insurance, and utilities

AI used to evaluate the eligibility for and grant of public benefits, to assess creditworthiness, to determine insurance premiums, and for emergency service dispatching. Includes AI credit scoring and AI-assisted loan underwriting.

Law enforcement

6

Very low — applies to police and law enforcement authorities

AI used by law enforcement authorities to assess crime risk, as polygraphs, for analysis of deep fakes in criminal investigations, and related purposes. Does not typically apply to private-sector SMEs.

Migration, asylum, and border control

7

Very low — applies to immigration and border authorities

AI used to assess irregular migration risks, to assist in examination of visa and asylum applications, and for border management. Applies to relevant public authorities and large-scale service providers in this sector.

Administration of justice and democratic processes

8

Very low — applies to courts and electoral administration

AI used to assist judicial authorities in researching and interpreting facts and the law and in applying the law to concrete facts, and AI used to influence the outcome of elections.

Article 26 — Deployer obligations for Annex III AI

If you deploy an Annex III high-risk AI system, Article 26 requires you to:

Implement human oversight measures

Ensure appropriate human oversight for the AI system's operation and outputs, including clear procedures for when human intervention or override is required.

Monitor operation and report incidents

Monitor the AI system for risks and, where required, report serious incidents to the relevant market surveillance authority.

Conduct a fundamental rights impact assessment (FRIA)

Before deploying certain Annex III AI systems (particularly those affecting large populations or making consequential decisions), prepare a FRIA documenting the potential impact on fundamental rights and the mitigation measures in place.

Register the AI system in the EU AI database

Deployers of specific Annex III AI systems must register them in the EU-wide public AI database before deployment.

Inform employees

Where the AI system affects or makes decisions about employees, ensure those employees are informed that they are subject to the AI system's operation.

How to prepare now for December 2027

  • Build your AI system inventory — identify every AI tool your business uses and assess each against the Annex III categories
  • For each potentially high-risk AI, obtain the provider's technical documentation and conformity information
  • Begin scoping your fundamental rights impact assessment for each Annex III system
  • Identify what human oversight measures you need and start implementing them
  • Monitor European AI Office guidance as it is published — supervisory expectations are being defined in 2026

Frequently asked questions

Does using an AI CV screening tool make my business subject to Annex III high-risk obligations?

Yes. AI used for recruitment and selection of natural persons, including CV screening, candidate ranking, and interview analysis, falls under Annex III point 4 (employment, workers management, and access to self-employment). As a deployer of such a system, the Article 26 obligations will apply to your business from 2 December 2027. You do not need to wait until December 2027 to begin preparing.

The AI tool I use for HR is provided by a major software vendor. Are their compliance measures sufficient for me?

No — not automatically. The provider has obligations (such as making technical documentation available), but as the deployer, you retain specific duties under Article 26 that cannot be delegated to the provider. These include conducting your own fundamental rights impact assessment, implementing human oversight measures appropriate to your context, and cooperating with supervisory authorities if required. Your provider's compliance does not substitute for your own.

How do I know whether an AI system I use is "high-risk" under Annex III?

Annex III lists eight categories of high-risk AI systems. For each system you use, assess: (1) Does it match one of the eight listed use-cases? (2) Is it intended to be used in a high-risk context (e.g. employment decisions, credit assessment, educational grading, or access to essential services)? If yes to both, the system is likely high-risk. Some AI systems are specifically excluded from Annex III scope by Article 6(3) — narrow-purpose AI with limited impact on decision-making. Check the full Article 6 conditions if you believe an exclusion may apply.

What is a fundamental rights impact assessment and how do we do one?

A fundamental rights impact assessment (FRIA) is a structured review — required under Article 26(9) for deployers of certain Annex III AI systems — evaluating how the AI system's outputs could affect the rights of the individuals it affects. It covers the intended purpose, the population of people affected, the nature of potential impacts on rights such as non-discrimination, privacy, and access to services, and what mitigation measures are in place. The European AI Office is expected to publish guidance and templates. For now, begin by documenting the AI system, its decision context, and the rights potentially at stake.

Can we keep using our existing AI systems in high-risk categories after December 2027 without complying with Chapter III?

No. From 2 December 2027, deploying an Annex III high-risk AI system without meeting the Article 26 obligations exposes your business to regulatory action. Systems already in use by that date are not automatically grandfathered — transition arrangements are limited. Begin compliance preparation well before the deadline.
