Directive 2006/43 - Statutory audits of annual accounts and consolidated accounts


Summary of Legislation

The statutory audit — ensuring accurate company financial statements


Directive 2006/43/EC on statutory audits of annual accounts and consolidated accounts


  • It merges two existing pieces of legislation (Directive 78/660/EEC on individual financial statements and Directive 83/349/EEC on consolidated financial statements) so as to improve the reliability of companies’ financial statements.
  • It lays down minimum requirements for the statutory audit* of annual and consolidated accounts.
  • It seeks to ensure that company accounts give a true and fair picture of businesses’ assets, liabilities, financial position and profit or loss.
  • This summary takes into account the fact that Directive 2006/43/EC has been amended 3 times by Directive 2008/30/EC, Directive 2013/34/EU (which contains the European Union (EU) rules on accounting) and Directive 2014/56/EU.


Public register of auditors

  • Statutory audits may only be carried out by statutory auditors or audit firms approved by EU countries’ competent authorities.
  • EU countries must keep a public register of these.

Recognition of audit firms outside their home country

  • An audit firm wishing to carry out statutory audits in an EU country other than its home EU country must register with the competent authority in the host country.
  • The competent authority in the host country must register the audit firm if it has been registered with the competent authority in its home country.

Approval of statutory auditors from another EU country

Auditors from other EU countries may have to complete an adaptation period (no more than a maximum of 3 years) and/or tests. This ensures they have adequate knowledge of matters such as company law, tax law and social law. Once they have been approved, they must be entered in the public register.

Continuing education

  • Statutory auditors are required to take part in continuing education to maintain and upgrade their theoretical knowledge, skills and values.
  • If they fail to respect these continuing education requirements, they will be subject to sanctions.

Independence and objectivity

  • EU countries have to ensure that, when carrying out their work, a statutory auditor or an audit firm, and any natural person in a position to directly or indirectly influence the outcome of the statutory audit, is independent of the audited entity and is not involved in the decision-taking of the audited entity.
  • Independence is required both during:
    • the period covered by the financial statements to be audited; and
    • the period when the statutory audit is carried out.

Confidentiality and professional secrecy

  • Auditors are bound by strict rules to respect the privacy of their clients; however, these rules should not impede the proper enforcement of the directive.
  • These rules continue to apply to audit firms which have ceased to be involved in a specific audit task.

International standards

All statutory audits should be carried out on the basis of international auditing standards, if and when adopted by the European Commission: The Commission has discretionary power to adopt these standards and it can adopt them only if they respect certain conditions. As long as the Commission has not adopted any international standard, EU countries may apply national standards.

Appointment and dismissal

  • The statutory auditor or audit firm is appointed by the general meeting of shareholders or members of the audited entity, although EU countries may allow alternatives as long as the independence of the statutory auditor or audit firm from the audited entity is assured.
  • Auditors or audit firms may be dismissed only where there are proper grounds. Divergence of opinions on accounting treatments or audit procedures is not proper ground for dismissal.

Auditing of consolidated accounts

In the case of consolidated accounts (i.e. of a parent company and subsidiaries), there is a clear definition of responsibilities between the auditors who audit components of the group. The group auditor (i.e. the statutory auditor or audit firm carrying out the audit of the consolidated accounts) bears full responsibility for the audit report.

Quality assurance

  • EU countries have to introduce a system of quality assurance that is independent of the reviewed auditors and subject to public oversight.
  • The system includes an assessment of:
    • compliance with applicable auditing standards and independence requirements;
    • the quantity and quality of resources spent;
    • the audit fees charged; and
    • the internal quality control systems of the audit firms.
  • The funding for the quality assurance system must be secure and free from any possible undue influence by statutory auditors or audit firms.
  • Reviewers for specific quality assurance review assignments must be selected by means of an objective procedure designed to ensure that there are no conflicts of interest between the reviewers and the statutory auditor or audit firm under review.

Investigations and sanctions

  • EU countries must have in place effective systems of investigations and sanctions to detect, correct and prevent inadequate execution of the statutory audit.
  • Measures taken and sanctions imposed on statutory auditors and audit firms must be appropriately disclosed to the public. Sanctions must include the possibility of withdrawal of approval.

Small businesses

  • There is no EU requirement for small companies to have a statutory audit.
  • Where EU countries do require statutory audits of small businesses, these should be conducted taking into account the scale and activities of the companies in question.

Public-interest entities (PIEs)*

The statutory audit of PIEs — because of the need for reliable information and their relevance to the public and investors — is subject to strict rules. These include:

  • a more detailed audit report which includes information about the conduct of the audit;
  • auditors/auditing firms must rotate;
  • a list of non-audit services that cannot be provided by the statutory auditor or audit firm to the audited entity which must be drawn up by EU countries;
  • limits must be placed on fees charged for non-audit services;
  • an audit committee is created which has a key role in appointing the auditor and monitoring the audit.

Regulation (EU) No 537/2014 contains further rules specifically applicable to PIEs.

Implementing and delegated acts

The directive allows the Commission to adopt implementing and delegated acts regarding the international aspects of the directive. These can further specify how EU countries’ authorities and the various market participants must comply with the obligations laid down in the directive in this sphere.


It has applied since 29 June 2006. EU countries had to incorporate it into national law by 29 June 2008.
