Definition and Significance of the Audit Opinion
The audit opinion is a central instrument in German commercial law for external accounting and audit processes. It constitutes the formalized audit judgment of an auditor, typically a certified public accountant or an audit firm. The audit opinion presents the outcome of the statutory or voluntary audit of annual financial statements and, if applicable, the management report. The audit opinion is addressed particularly to shareholders, creditors, the general public, and other interested parties, and is essential for the transparency and credibility of corporate reporting.
Legal Basis and Statutory Framework
German Commercial Code (HGB)
The principal legal basis for the audit opinion is found in the German Commercial Code (HGB), especially in §§ 322 and 316 ff. HGB. According to § 322 (1) HGB, the auditor is required, upon completion of the audit, to issue a written audit opinion (audit certificate) regarding the audit of the annual and, where applicable, consolidated financial statements as well as the management report.
Pronouncements of the Institute of Public Auditors (IDW)
In addition, professional standards and pronouncements, such as those issued by the Institute of Public Auditors in Germany (IDW), are crucial for the precise content and formal structure of the audit opinion. It is particularly important to comply with the International Standards on Auditing (ISA), which in Germany are implemented through IDW PS 400 ff.
Other Relevant Laws
Further applicable regulations are set out in the German Stock Corporation Act (AktG), Limited Liability Company Act (GmbHG), Publicity Act (PublG), as well as in industry-specific regulations, such as for credit institutions (KWG) and insurance companies (VAG).
Content and Structure of the Audit Opinion
The audit opinion typically consists of designated components whose structure and content are bindingly regulated by law and professional standards.
General Information
The audit opinion includes information about the audited company, the type and scope of the audited financial statements (individual or consolidated financial statements), as well as details of the statutory and, if relevant, additional audit requirements.
Description of the Audit
This section describes the audit engagement with reference to statutory provisions and the auditing standards applied. In particular, the responsibilities of the legal representatives and the auditor are presented.
Audit Opinion
The audit opinion is the central component of the audit certificate. It comprises the assessment of whether
- the annual financial statements comply with statutory requirements and, where applicable, with further accounting principles,
- a true and fair view of the company’s assets, financial position, and results of operations is conveyed,
- the management report is consistent with the annual financial statements.
The opinion is typically issued as an unqualified audit certificate. If there are reservations, denials, or qualified findings, these are to be explained.
Additional Notes and Other Matters
Depending on the nature and scope of the audit, additional notes can be included, such as violations of statutory regulations, significant uncertainties regarding the company’s ability to continue as a going concern, or relevant subsequent events.
Conclusion and Signature
The audit opinion must be personally signed by the responsible auditor and contain the date.
Types of Audit Opinions
Unqualified Audit Opinion
This is issued when the audit did not reveal any objections concerning the proper accounting and the financial statements present a true and fair view.
Qualified Audit Opinion
If there are limited objections that do not affect the overall validity of the financial statements, the auditor issues a qualified audit opinion explicitly outlining the qualifications.
Disclaimer of Opinion
If an audit opinion in accordance with statutory requirements cannot be given, a disclaimer of opinion will be issued. A disclaimer may also be given with regard to specific parts of the financial statements (partial disclaimer).
Audit Opinion with Notes
In the case of significant matters outside the auditor’s assessment, the opinion may be supplemented with notes, for example, regarding legal risks or substantial uncertainties.
Form and Publication
Form of the Audit Opinion
The audit opinion must be prepared in writing and personally signed (§ 322 (1) HGB). Electronic transmission is only permissible if authenticity and integrity are ensured.
Publication Requirement
The obligation to publish the audit opinion applies to publicly traded companies, large corporations, and other companies subject to audit as defined in § 316 HGB. When filing to the company register, the original wording of the audit opinion must be included.
Retention and Submission
The audit opinion must be retained by the audited company and be presented as part of the statutory disclosure obligations.
Function and Relevance in Legal Transactions
The audit opinion is a crucial signal of trust in commercial transactions. It forms a key basis for decision-making for shareholders, investors, creditors, employees, tax authorities, and other stakeholders. An unqualified audit opinion is a prerequisite for dividend resolutions, discharge of management, and is often required for obtaining credit or performing other legal acts in connection with the audited company.
Liability and Legal Consequences
Liability of the Auditor
Issuing the audit opinion entails special civil and, where applicable, criminal liability for the auditor. In the event of an erroneous audit or the issuance of an incorrect audit opinion, the auditor is liable to the audited company as well as to third parties under certain conditions (§ 323 HGB, tort law).
Legal Consequences of a Disclaimed or Qualified Opinion
If the opinion is qualified or denied, the company’s management bodies are obliged to present this to the shareholders’ meeting. A disclaimed audit opinion can have consequences under liability and capital markets law, as, for example, dividend distribution restrictions under § 268 (8) HGB and other legal effects may apply.
Developments and Reforms
In the course of European harmonization efforts and the implementation of the Accounting Directive Implementation Act (BilRUG) as well as the audit oversight reform, the structure and transparency requirements for the audit opinion have further developed. Since 2017, expanded disclosures of Key Audit Matters (KAM) have been mandatory for certain entities.

Frequently Asked Questions
Who is legally authorized to issue the audit opinion?
As a rule, the issuance of the audit opinion is reserved exclusively for the appointed auditor, who under § 318 HGB is responsible for the statutory audit of a corporation or other audit-obligated company. In Germany, auditors are primarily certified public accountants or audit firms, who according to § 319 HGB must be independent and licensed to conduct statutory audits. Additionally, the authority to issue an audit opinion must be explicitly set out in the audit engagement as per § 317 HGB. Unauthorized issuance of an audit opinion constitutes a breach of professional rules and can have professional and civil law consequences, as the audit opinion is a sovereign audit judgment of significant legal importance for the intended recipients of the annual accounts (e.g., shareholders, creditors, public).
In what legal context is the issuance of an audit opinion mandatory?
The statutory requirement to issue an audit opinion is set forth in § 322 HGB and primarily concerns companies required to be audited as per § 316 HGB, such as medium-sized and large corporations, certain partnerships, and public interest entities (PIEs). In case of voluntary audits, audit opinions may also be issued if contractually agreed. The legal framework provides that the audit opinion may only be issued if the audit judgment is entirely positive and there are no grounds for disclaimer. The precise structure and minimum content of the audit opinion are set out in § 322 (2) to (4) HGB and the relevant professional standards, such as IDW PS 401 ff.
What legal obligations does the auditor have in connection with the audit opinion?
The auditor is required to issue the audit opinion independently, impartially, and in accordance with the statutory and professional regulations (§§ 43, 57 WPO, §§ 317, 322 HGB). In doing so, the auditor must particularly observe the principles of proper auditing (GoA) and disclose all significant matters and uncertainties that could influence the audit judgment. Special emphasis is placed on the duty to appropriately indicate any modifications, such as a qualified or disclaimed opinion, in accordance with legal requirements. There are also retention and documentation obligations (at least 6 years according to § 51b WPO) to ensure traceability of audit judgments for third parties and to secure liability protection for the auditor.
What are the legal consequences of an incorrect audit opinion?
An incorrect or unauthorized audit opinion can have significant liability and criminal consequences for the auditor. Civil liability is established under § 323 HGB in favor of company creditors and the audited company itself if culpability is proven. In cases of intent, gross negligence, or criminal offenses such as issuing false certificates (§ 348 German Criminal Code), professional disciplinary action and criminal penalties may also apply. Professionally, disciplinary proceedings with the risk of fines or withdrawal of professional license may be imposed. The legal validity of contracts concluded on the basis of an incorrect audit opinion generally remains unaffected; however, affected parties may claim damages in case of loss.
How must the audit opinion be legally attached to the annual financial statements?
According to § 322 (1) sentence 2 HGB, the audit opinion must be issued in written form and the signed audit opinion must be inseparably attached to the audited financial statements in accordance with the statutory provisions; this also applies to the management report. As of current law and professional interpretation, the audit opinion must be a separate, clearly identifiable document containing the identity of the audit firm, audit location, date, and the signature of the responsible auditor. Attachment can be accomplished – depending on practical circumstances – by binding or by a reference on the cover page, provided unalterability and verifiability are assured. Upon disclosure of the financial statements, the audit opinion is a mandatory component (§ 325 HGB).
Under what legal conditions may the audit opinion be disclaimed or qualified?
An audit opinion must be withheld if there are material impediments to the audit, irreparable uncertainties, or serious violations of accounting standards that fundamentally affect the true and fair view of the financial statements (§ 322 (3) HGB). Qualifications must be made when deficiencies exist that affect parts but not the overall result of the audit (§ 322 (3) sentence 2 HGB). The precise formulation and justification of such modifications must be detailed in the audit opinion, taking into account the respective legal requirements and professional standards. The auditor must also clearly inform the recipients about the scope and content of any qualifications or disclaimers.
What legal information and disclosure obligations exist in connection with the audit opinion?
Corporations and other audit-obligated companies are required under § 325 HGB to file the audit opinion, together with the annual financial statements and, if applicable, the management report, electronically with the Bundesanzeiger (Federal Gazette) no later than twelve months after the balance sheet date. The same applies to disclosures under other specific laws (e.g., PublG, VAG, or for banks under KWG and CRR). A missing or late disclosure of the audit opinion can lead to penalty proceedings by the Federal Office of Justice (§ 335 HGB) and possibly further sanctions. Within the company, the audit opinion must be provided without delay to the corporate bodies, such as the supervisory board, as it constitutes a significant basis for their oversight and discharge decisions (§ 171 (1) AktG).
