Non-Federal Audit Main page

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 Administrative Relief for Recipients Impacted by the Novel Coronavirus (COVID-19): OMB has issued three memos providing short term relief for administrative, financial management, and audit requirements under 2 CFR Part 200, in response to COVID-19. Memo M-20-11 provided flexibility to grant recipients performing essential research and services necessary to carry out the emergency response related to COVID-19, while M-20-17 provided similar relief to an expanded scope of recipients affected by the loss of operational capacity and increased costs due to the COVID-19 crisis. Under M-20-17, recipients and subrecipients were allowed to delay the completion and submission of the Single Audit to six months beyond the normal due date, without seeking individual approval from ED. However, Memo M-20-26 significantly reduces the flexibilities provided in M-20-17 and rescinds it. Please read the memos for additional detail.

  • 2020 Compliance Supplement (August 2020) (Note: OMB plans to work with Federal awarding agencies to identify the new COVID-19 programs with special compliance and reporting requirements that will be included as an Addendum to this Supplement, as appropriate.)
  • 2019 Compliance Supplement (August 2019) (Important Note to Auditors and Auditees in the Federal Audit Clearinghouse Database: On September 20, 2019, the OMB issued this corrected edition of the 2019 Compliance Supplement (Supplement) which is dated August 2019 and replaces the previously released edition dated June 2019. For Single Audits subject to the 2019 Supplement, auditors are permitted to perform the audit using either the June 2019 or August 2019 edition of the Supplement for reports dated on or before October 31, 2019. Please document the version of the supplement that is used for the audit. Auditors are required to perform the audit using the August 2019 edition for reports that are dated after October 31, 2019)
  • 2018 Compliance Supplement (Note: Auditors must use the 2018 supplement and the 2017 supplement together. See the subsection titled “Purpose” within Part 1 for further explanation).
  • 2017 Compliance Supplement
