The Yellow Book

The Generally Accepted Government Auditing Standards, also known as the Yellow Book, provide a framework for conducting high quality audits with competence, integrity, objectivity, and independence. The Yellow Book is for use by auditors of government entities, entities that receive government awards, and other audit organizations performing Yellow Book audits.

The Yellow Book is the book of standards and guidance for auditors and audit organizations, outlining the requirements for audit reports, professional qualifications for auditors, and audit organization quality control. Auditors of federal, state, and local government programs use these standards to perform their audits and produce their reports.

Revising the Yellow Book

GAO is seeking public comment on the draft of the 2017 revision of the Yellow Book. The draft will be available for review from April 5, 2017, until July 6, 2017. Please send your comment letters to our Yellow Book Comments inbox, YellowBookComments@gao.gov, no later than July 6, 2017.

Along with changes to its format and structure, the draft contains updates on the following topics:

  • Independence
  • Competence and Continuing Professional Education
  • Quality Control and Peer Review
  • Financial Audits
  • Attestation Engagements and Reviews of Financial Statements
  • Performance Audits

Yellow Book revisions undergo an extensive, deliberative process, including public comments and input from the Comptroller General's Advisory Council on Government Auditing Standards. GAO considers all Yellow Book comments and input from the Comptroller General's Advisory Council on Government Auditing Standards in finalizing revisions to the standards. You can find our Yellow Book publications, including other important guidance documents, below. These other guidance documents aid auditors in planning and performing Yellow Book audits.

Obtaining Printed Copies of the Yellow Book

The printed version of the December 2011 revision of the Yellow Book can be purchased through the Government Publishing Office (GPO) online or by calling 202-512-1800 or 1-866-512-1800.

Related Standards and Guidance

Auditors may use the Yellow Book in conjunction with professional standards issued by GAO and other authoritative bodies. In addition, GAO issues guidance on implementing and complying with standards.

Professional Standards Updates

Professional Standards Updates (PSUs) 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 official views on these requirements. Users should refer to the original, authoritative standards for purposes of implementing the standards.
