Generally Accepted Auditing Standards (GAAS)

Updated on Aug 10, 2026

What Are Generally Accepted Auditing Standards (GAAS)?

Auditing is a crucial process in any organisation. An auditor's primary job is to verify transactions and track changes that affect their integrity, such as changes to dates, ledger masters, and amounts in a voucher.

While performing these checks, auditors must follow a set of mandatory guidelines. These are known as Generally Accepted Auditing Standards (GAAS).

GAAS was established by the Auditing Standards Board (ASB) of the American Institute of Certified Public Accountants (AICPA). It ensures that auditors maintain accuracy, consistency, and verifiability when reviewing the quality of a company's financial records.

Once auditors complete their checks, they must ensure the audit report complies with GAAS. This process helps auditors confirm that the reports are correct and that the company's financial statements follow GAAP (Generally Accepted Accounting Principles).

Requirements for Accounting Standards

Now that we've covered what GAAS is, let's look at the 10 standards an auditor must follow.

These are divided into three categories:

General standards,
Standards of field work, and
Standards of reporting.

All 10 were approved and adopted by the AICPA, as amended by the Auditing Standards Board (ASB).

1. General Standards

The auditor must have adequate technical training and proficiency to perform the audit
The auditor must maintain independence in mental attitude in all matters relating to the audit
The auditor must exercise due professional care in the performance of the audit and the preparation of the auditor's report.

2. Standards of Field Work

The auditor must adequately plan the work and must properly supervise any assistants
The auditor must understand the entity, its environment, and internal controls to assess misstatement risks and plan further audit procedures.
The auditor must obtain sufficient appropriate audit evidence by performing audit procedures to afford a reasonable basis for an opinion regarding the financial statements under audit.

3. Standards of Reporting

The auditor must state in the auditor's report whether the financial statements are presented in accordance with generally accepted accounting principles
The auditor must identify in the auditor's report those circumstances in which such principles have not been consistently observed in the current period in relation to the preceding period
If the auditor determines that informative disclosures in the financial statements are not reasonably adequate, the auditor must so state in the auditor's report
The auditor’s report must express an opinion on the financial statements or explain why an opinion cannot be given, while clearly stating the auditor’s work and level of responsibility.
