Auditors of government entities and entities that receive government awards use our Government Auditing Standards, commonly referred to as generally accepted government auditing standards (GAGAS) or the Yellow Book, to perform their audits and produce their reports. The Yellow Book outlines the requirements for audit reports, professional qualifications for auditors, and audit organization quality management.
Current Yellow Book
The 2018 Yellow Book is also available in a digital format.
The 2018 Yellow Book with the 2021 technical update can be purchased online through the Government Publishing Office at GPO Bookstore- Government Auditing Standards- 2018 Revision with 2021 Technical Update or by calling 202-512-1800 or 1-866-512-1800.
Amendments & Interpretive Guidance
At this time, there are no amendments or interpretive guidance for the 2018 revision of Government Auditing Standards.
Revising the Yellow Book
We are proposing a 2023 revision of the Yellow Book, which updates Chapter 5: Quality Control and Peer Review. The proposed revision reflects enhancements to strengthen an audit organization’s framework for conducting high-quality engagements through its system of quality management. We are also proposing guidance to address key audit matters in financial audits. GAO received comments on the Exposure Draft from January 30, 2023 through April 28, 2023.

GAO provides comments to other standard-setting organizations’ proposals in letter form. The comment letters discuss technical issues related to ethics, quality control, accounting, auditing, and attestation standards. By issuing comment letters, GAO promotes the development of high-quality government and private sector auditing standards, both domestically and internationally. Listed below are comment letters relating to auditing standards and other topics of interest to the accounting and auditing community.
Auditors may use the Yellow Book in conjunction with professional standards issued by GAO and other authoritative bodies. GAO also issues guidance on implementing and complying with standards.
Professional Standards Updates (PSU) summarize recently-issued standards of major auditing and accounting standard-setting bodies. These updates inform the Yellow Book user community of important changes to professional requirements. These updates do not establish new professional standards and do not reflect GAO's official views on these requirements. Users should refer to the original, authoritative standards for purposes of implementing the standards.
