An audit opinion is a formal statement issued by an auditor regarding the fairness of the presentation of an entity's financial statements, based on applicable auditing standards. This opinion is the final conclusion of the entire audit process and determines the extent to which the financial reports can be relied upon by stakeholders—from management, investors, regulators, to the public.
In Indonesia, audit opinion refers to Standard Audit (SA) published by the Indonesian Institute of Certified Public Accountants (IAPI), specifically SA 700–705, as well as the provisions of the Supreme Audit Agency (BPK) for government financial reports. This article discusses the definition of an audit opinion, the four types of opinions according to standards, the stages of its formation, influencing factors, and examples of its application in both the corporate and public sectors.
Understanding Audit Opinion
An audit opinion is the auditor's professional conclusion on the fairness of the financial statements after conducting an audit in accordance with auditing standards. Fairness here does not mean that the statements are completely free from error, but rather that the financial statements are presented fairly in all material respects in accordance with the applicable financial reporting framework (e.g., SAK or SAP).
According to Public Accountant Professional Standards (SPAP), an audit opinion is a statement of opinion submitted by an independent auditor after collecting and evaluating audit evidence sufficient and appropriate. This opinion is stated in the independent auditor's report accompanying the financial statements.
It's important to understand that an audit opinion is not a guarantee that a company is financially sound or free from the risk of fraud. The opinion only assesses whether the financial statements fairly reflect the entity's condition and comply with accounting standards.
Function of Opinion Audit
Audit opinions have several main functions for both entities and external parties:
- Increase the credibility of financial reports. The opinion of the independent auditor provides assurance that the report has been examined objectively.
- The basis for stakeholder decision making. Investors, creditors, and regulators use audit opinions to assess the reliability of financial information before making decisions.
- Benchmark for governance improvement. An opinion other than Unqualified is a signal for management to improve the internal control and reporting system.
- Fulfillment of regulatory obligations. For public companies, state-owned enterprises, and government agencies, an audit opinion is a mandatory compliance requirement.
Stages of Forming an Audit Opinion
An audit opinion doesn't emerge instantly, but rather is the result of a systematic audit process. The main stages are as follows.
1. Audit Planning
Auditors develop strategies and audit plan, including understanding the client's business, assessing the risks of material misstatement, and determining materiality level. Careful planning determines the direction and scope of testing.
2. Understanding and Testing Internal Control
The auditor evaluates the effectiveness of the entity's internal controls. If the controls are deemed reliable, auditor can reduce substantive testing; if weak, testing is expanded.
3. Substantive Testing
At this stage the auditor gathers evidence through testing of account balances and transactions—confirmations, document inspections, recalculations, and analytical procedures—to detect material misstatements.
4. Evaluation of Evidence and Formulation of Opinions
The auditor evaluates the sufficiency and appropriateness of the audit evidence and then forms an opinion. The availability of evidence and the degree of material misstatement determine the type of opinion issued.
5. Reporting
The opinion is stated in the independent auditor's report and submitted to management and interested parties.
4 Types of Audit Opinions According to Standards
Auditing Standards (SA 700 and SA 705) recognize four types of audit opinions. The following explains each.
1. Unqualified Opinion (WTP)
The best opinion an auditor can provide. An unqualified opinion states that the financial statements are presented fairly, in all material respects, in accordance with the applicable reporting framework. The auditor obtained sufficient evidence and found no material misstatements.
Under certain conditions, the auditor may add paragraph emphasizing a matter (emphasis of matter) without changing the WTP opinion—for example to reveal the issue of business continuity (going concern) which have been adequately disclosed in the report.

2. Qualified Opinion (WDP)
The auditor provides a WDP opinion when he finds a material misstatement. non-pervasive (not comprehensive), or when sufficient audit evidence cannot be obtained on a particular matter, but the impact is limited. This means that the financial statements as a whole are still fair, except for the excluded matters.

3. Adverse Opinion
An adverse opinion is issued when the auditor concludes that misstatements—either individually or in the aggregate—are material and pervasive, so that the financial statements as a whole do not fairly present the entity's condition. This is a serious signal that the financial statements are unreliable.

4. Disclaimer of Opinion
The auditor does not express an opinion when unable to obtain sufficient and appropriate audit evidence, and the potential impact of the unavailability of such evidence is material and pervasive. In this situation, the auditor declines to provide an opinion because there is no sufficient basis to conclude that the report is fair.
Important notes: “Disapproval opinion” or disclaimer often mistaken for a separate type. By default, a refusal to give an opinion same as disclaimer of opinion—both refer to the same condition, namely that the auditor does not have a sufficient basis for an opinion.

Audit Opinion in the Context of the Public Sector (BPK)
For government financial reports—both the Central Government Financial Report (LKPP), Regional Government Financial Report (LKPD), and BUMN/BUMD—opinions are provided by the Audit Board of Indonesia (BPK) with four types of opinions that are equivalent to audit standards:
- WTP (Unqualified Opinion) — highest opinion, often becomes the performance target of government agencies and state-owned enterprises.
- WDP (Fair With Exceptions)
- TMP (Disclaimer)
- TW (Unnatural)
For public sector entities and state-owned enterprises, obtaining an unqualified opinion from the BPK is not just a formality, but an indicator of accountability and good financial governance (good governanceThis opinion is often part of the key performance indicators (KPI) and is of concern to the Inspectorate and the Internal Audit Unit (SPI).
Factors Affecting Audit Opinion
Several factors determine the type of opinion the auditor gives:
- Sufficiency and accuracy of audit evidence. The more complete and reliable the evidence, the stronger the auditor's basis for issuing an unqualified opinion. Limited evidence can lead to an unqualified opinion or a disclaimer.
- The level of materiality and pervasiveness of misstatements. Minor misstatements may be ignored; material misstatements determine whether the opinion is WDP, adverse, or other.
- Effectiveness of internal control. Weak internal controls increase the risk of misstatement and affect the extent of testing and the auditor's conclusions.
- Compliance with accounting standards. Material deviations from SAK/SAP can reduce the quality of the opinion.
- Going concern issues. Significant doubt about an entity's ability to continue as a going concern may trigger an emphasis of the opinion paragraph or influence the opinion.
Examples of Audit Opinion Application
The following illustrates how audit opinions arise in practice:
- Public companies obtain WTP after the auditor ensures that the financial statements are presented fairly in accordance with SAK, with adequate internal controls and complete audit evidence.
- The issuer received an unqualified opinion with a paragraph emphasizing going concern. due to a working capital deficit, even though the disclosure has been adequate—the opinion remains fair, but readers are reminded of the sustainability risks.
- BUMD receives WDP from auditors due to the recording of fixed assets that cannot be fully verified, but does not affect the report as a whole.
- Government agencies obtain TMP from the BPK Due to limited evidence on a number of material transactions, the BPK was unable to conclude the fairness of the report.

A quality audit opinion begins with a well-documented audit process—from planning and testing to reporting findings. For internal audit teams in state-owned enterprises (BUMN), regional-owned enterprises (BUMD), and government agencies, managing this entire cycle manually often makes it difficult to track evidence and maintain consistent working papers.
