What Is an Accountant's Opinion?

4 Min.

An accountant's opinion is a statement provided by an unbiased accountant that expresses their assessment of the accuracy and reliability of the financial information presented in a set of reports. In the U.S., audits can have three types of opinions: unqualified and following Generally Accepted Accounting Principles (GAAP), qualified, or adverse. When filing an annual report (Form 10-K), an accountant's opinion is included. This opinion is divided into three sections, or four if it is not unqualified. If an accountant cannot finish an audit due to inadequate financial records or insufficient cooperation from management, they may issue a disclaimer of opinion.


When it comes to financial reports, the accountant's opinion holds great importance. It is a professional statement formulated by an independent certified accountant, offering an assessment of the accuracy and reliability of the information presented.

When conducting audits in the United States, accountants issue opinions that fall into three categories: unqualified, qualified, or adverse. These classifications are determined by how much a company's financial statement aligns with the generally accepted accounting principles. The GAAP represents a standardized framework of guidelines and procedures established by the Financial Accounting Standards Board (FASB), mandating compliance for all publicly traded entities in the U.S.

Enhancing Financial Transparency: The Role of an Accountant's Opinion

The assessment of financial statements is a crucial undertaking for investors and analysts, as it influences the trajectory of stock prices. These written records, serving as a window into a company's operations and financial performance, must be diligently prepared, accurately reflective, and easily comparable with others.

To instill confidence in financial statement reliability, including an accountant's opinion is paramount. Incorporated within an auditor's report, which accompanies the annual filing (Form 10-K), these brief statements are issued by qualified professionals entrusted with the meticulous examination and synthesis of financial accounts.

Accountant opinions typically comprise three core sections, each playing a distinctive role:

  1. An initial declaration elucidates the responsibilities of both management and the auditing firm.
  2. Identification of the financial statements under scrutiny, specifying the focus of the accountant's opinion.
  3. The expression of the opinion itself.

In certain cases, supplementary segments may provide further elucidation concerning opinions that deviate from an unqualified stance. The absence of an accountant's opinion in the annual filings of publicly traded companies can elicit concerns and warrant increased vigilance.

Types of Accountant's Opinions

When accountants examine a company's financial accounts, they may have varying opinions based on their findings. Broadly speaking, three distinct opinions are registered: unqualified, qualified, and adverse.

Unqualified Opinion 

Termed a clean opinion, an unqualified opinion is provided by accountants when the financial statement is deemed free from significant errors or misrepresentations. This signifies that all alterations, accounting policies, their application, and resulting impacts have been accurately disclosed. Additionally, an unqualified opinion may extend to encompass the assessment of internal controls, provided management claims responsibility for their establishment and maintenance and the accountant has performed due diligence to evaluate their efficacy.

Qualified Opinion 

A qualified opinion arises when a company's financial records partially deviate from the stipulated GAAP without any indication of intentional misconduct. While there are no apparent false statements, the accounting standards have not been completely followed. In such instances, accountants append an explanatory paragraph to their opinion letters, elucidating the reasons for the deviations and offering guidance for rectification.

Adverse Opinion 

An adverse opinion represents the most unfavorable assessment a company can receive. It signals substantial violations of key GAAP principles and the presence of material misstatements. An adverse opinion often serves as an indicator of potential fraud. Companies receiving such an opinion are required to rectify their financial statements and undergo subsequent audits. Financial statements bearing adverse opinions are typically rejected by investors, lenders, and other financial institutions due to the underlying concerns raised.

Navigating Challenges: The Accountant's Disclaimer of Opinion

Encountering obstacles such as a scarcity of financial records or uncooperative management during an audit, accountants may be unable to conclude their assessment. In such circumstances, they are obliged to issue a disclaimer of opinion. Unlike an accountant's opinion, a disclaimer does not provide an evaluation or judgment on the financial statements. Instead, it signifies the inability to reasonably formulate an opinion due to the aforementioned constraints.


An accountant's opinion is crucial in assessing the accuracy of financial information. It can be unqualified, qualified, or adverse, depending on compliance with accounting standards. Including this opinion in annual filings enhances transparency and confidence. A disclaimer of opinion is issued when obstacles prevent a complete assessment. Accountants' opinions are essential for evaluating financial statements and maintaining integrity.
