NEW YORK (Aug. 19, 2026) – The American Institute of CPAs’ Auditing Standards Board (ASB) has approved a new standard that clarifies and enhances auditors’ responsibilities relating to fraud or suspected fraud in a financial statement audit.
The ASB’s adoption of Statement on Auditing Standards (SAS) No. 151, The Auditor’s Responsibilities Relating to Fraud in an Audit of Financial Statements, supersedes SAS No. 122, Statements on Auditing Standards: Clarification and Recodification, as amended (Section 240, Consideration of Fraud in a Financial Statement Audit), and amends several other standards. The new standard helps auditors more clearly understand their role in assessing risks of material misstatement due to fraud and their response when fraud or suspected fraud is identified in a financial statement audit.
SAS No. 151 strengthens audit procedures related to fraud while reinforcing that management and those responsible for governance of an entity remain primarily responsible for preventing and detecting fraud. The standard does not change the definition of fraud, nor does it change the auditor’s overall objective of obtaining reasonable assurance that financial statements are free of material misstatement due to fraud or error. But it adds more specific requirements designed to enhance auditor skepticism, fraud risk assessment, documentation, communication and responses when fraud is identified or suspected.
“It is critical for auditors to remain alert to the possibility of fraud throughout an audit engagement,” said Jennifer Burns, CPA, the AICPA’s chief auditor. “This standard reinforces the importance of professional skepticism and provides clearer direction for how auditors should respond when fraud is identified or suspected.”
SAS No. 151’s major changes include:
Enhancing the auditor’s risk identification and assessment process as it relates to fraud by providing a fraud lens when performing risk assessment procedures in accordance with AU-C section 315.
Requiring the auditor to understand the entity’s whistleblower program (or other program to report fraud), if the entity has such a program, including how management and, if applicable, those charged with governance address allegations of fraud made through the program.
Additional requirements governing how auditors respond when fraud or suspected fraud is identified, and more extensive requirements regarding communications with management and those charged with governance.
Leaves unchanged the presumption that fraud risks exist in revenue recognition, and requires auditors to determine which types of revenue transactions, or relevant assertions give rise to such risks.
The final version of the standard is expected to be posted online in October. SAS No. 151 will be effective for audits of financial statements for periods ending on or after Dec. 15, 2028, although firms can implement it earlier.
