Single Audit Library

New A-133:	The final version of OMB Circular A-133 was issued in June 1997. The revisions to the Circular implement the 1996 Amendments, extend OMB Circular A-133's coverage to States, local governments, and Indian tribal governments, and rescind OMB Circular A-128.
Compliance Supplement:	The OMB Circular A-133 Compliance Supplement is updated annually, and is based on the requirements of the 1996 Amendments and the final revision of OMB Circular A-133 which provide for the issuance of a compliance supplement to assist auditors in performing the required audits. This document serves to identify existing important compliance requirements which the Federal Government expects to be considered as part of an audit required by the 1996 Amendments. This Supplement also provides guidance to assist auditors in determining compliance requirements relevant to the audit, audit objectives, and suggested audit procedures for programs not included herein. For single audits, this Supplement replaces agency audit guides and other audit requirement documents for individual Federal programs.
Single Audit Act Amended	The Single Audit Act of 1984 established uniform entity-wide audit requirements for state and local governments receiving Federal financial assistance. Audits performed under the Single Audit Act are intended to satisfy all Federal agencies providing assistance to the entity. The act was amended in 1996 by Public Law 104-156, raising the threshold for Single Audit to $300,000 in Federal assistance. Federal grantor agencies with a substantial investment in grants to state and local governments have established guidelines for single audits. Non-Federal auditors retained by state and local governments follow the Federal guidelines in performing single audits.
