The Single Audit Act, as amended, establishes requirements for audits of States, local governments, Indian tribes, institutions of higher education (public or private nonprofit colleges and universities), and nonprofit organizations that expend a certain amount in Federal awards during its fiscal year (currently set at $750,000). The Single Audit Act amendments are implemented through Subpart F—Audit Requirements of Title 2 of C.F.R., Chapter II, Part 200 Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards (2 CFR part 200).
Single audits are performed by independent auditors and encompass both financial and compliance components. The Compliance Supplement is based on the requirements of the 1996 Single Audit Act Amendments and 2 CFR part 200, subpart F, which provide for the issuance of a compliance supplement to assist auditors in performing the required audits. See below for links to recent compliance supplements available from the Office of Management and Budget.
Important Note Regarding Single Audit Submission Extensions due to Weather Related Events: OMB announced on the Federal Audit Clearinghouse Web site that a six-month single audit submission extension is available to non-federal entity recipients in Puerto Rico, Alaska, Florida, South Carolina, and North Carolina that have due dates between September 18, 2022, and December 31, 2022. Although the extension is due to complications created by various weather-related events, the extension is available to all recipients in each of the states and not just those located in certain areas of the states most significantly impacted. OMB encourages recipients in less affected areas to submit their reports as soon as possible.

- Suggested Single Audit Procedures Related to NSLDS Enrollment Reporting: ED issued two electronic announcements, General-23-04 and General-23-24, that apply to single audits that include the Student Financial Assistance Cluster. The announcements communicate ED's expectations of auditors in light of NSLDS implementation issues that impacted an institution's ability to comply with enrollment reporting requirements.
