Yellow Book: Government Auditing Standards
Generally Accepted Government Auditing Standards (GAGAS), also known as the Yellow Book, provides the preeminent standards for government auditing.
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 contains standards for financial audits, attestation engagements, and performance audits as well as specific requirements for individual auditors and audit organizations.
Yellow Book Revisions
The 2018 Yellow Book is effective until implementation of the 2024 Yellow Book. The 2024 Yellow Book is effective for financial audits, attestation engagements, and reviews of financial statements for periods beginning on or after December 15, 2025, and for performance audits beginning on or after December 15, 2025. A system of quality management that complies with the Yellow Book is required to be designed and implemented by December 15, 2025, and an audit organization should complete an evaluation of the system of quality management by December 15, 2026. Early implementation of the 2024 Yellow Book is permitted.
Copies of the 2024 Yellow Book will be available for purchase at a later date through the Government Publishing Office at https://bookstore.gpo.gov/ or by calling 202-512-1800 or 1-866-512-1800.
