What changed for single audits in the 2024 Uniform Guidance revision?

In short: OMB's 2024 revision of 2 CFR 200 raised the single audit threshold from $750,000 to $1,000,000 of federal awards expended, raised the lowest Type A program threshold to $1,000,000, and raised the equipment threshold, the de minimis indirect cost rate and the subaward limit. The government-wide effective date is October 1, 2024 (Federal Register 2024-07496).

What changed?

Six changes in the revised text touch a single audit, an auditee's books or the audit timeline. Each row below was checked against the Federal Register document and against the eCFR text of the same section (Federal Register, current eCFR).

The Federal Register document is 163 pages (89 FR 30046) and changes much more than these six items. This page lists only the changes that touch the audit, and only the ones confirmed in both sources. The “Before” column is the eCFR text as it stood on September 30, 2024, read through the eCFR API (example).

When do the changes apply?

The government-wide effective date is October 1, 2024. A federal agency may choose to apply the guidance to awards it issued before that date but is not required to, and an agency that applies it early may not set an effective date earlier than June 21, 2024 (Federal Register 2024-07496).

• Agencies implement the guidance for their own awards. For an individual award, the Federal Register document says the agency that made the award is the best source on how it applies.
• Indirect cost rates follow a separate rule: existing negotiated rates stay in place until they expire, and a revision takes effect in a newly negotiated rate when that rate starts for the recipient's fiscal year (2 CFR 200.110(b)).
• The audit threshold has its own fiscal-year rule, separate from the general effective date above. The OMB 2025 Compliance Supplement, Part 1 says the revision increased the audit threshold to $1,000,000 for auditee fiscal years beginning on or after October 1, 2024, and that $750,000 applied to auditee fiscal years beginning on or after December 26, 2014 (Compliance Supplement, Part 1); the Federal Audit Clearinghouse states the same split (FAC submission guide). The Federal Register document does not tie the audit threshold to a fiscal-year start date; its effective date is the one for awards in the first paragraph. Our single audit threshold page applies the amounts by fiscal-year start date.

Did the single audit threshold change?

Yes. The threshold was $750,000 and rose to $1,000,000 of federal awards expended in the fiscal year (2 CFR 200.501). An entity that expends less than $1,000,000 in federal awards in its fiscal year is exempt from the federal audit requirements for that year (with the exceptions in 200.503), but its records must stay available to the federal agency, the pass-through entity and GAO. The single audit threshold glossary page has the same figures by fiscal-year start date.

• OMB says it weighed the number of entities that would benefit against the types of auditor opinions issued and the amount of questioned costs, and that this is the smallest percentage increase to the threshold to date. It also says the increase aligns closely with the Consumer Price Index since the last increase in 2014.
• The Director of OMB may adjust the threshold every two years, but not below $300,000 (31 U.S.C. 7502, as cited in the Federal Register document).
• A higher threshold does not remove monitoring: OMB says pass-through entities should keep monitoring subrecipients consistent with part 200 whether or not the audit requirement applies.

What did not change for auditors?

The core audit mechanics read the same in the September 30, 2024 and current eCFR text. The items below are the ones confirmed in both versions or stated in the Federal Register document.

• The report is still due the earlier of 30 calendar days after the auditee receives the auditor's report or nine months after the end of the audit period (2 CFR 200.512(a)(1)); the revision adds the extension in the table above.
• Audits are still annual unless a biennial audit is permitted under 200.504(a) or (b). The Federal Register document says OMB clarified the wording and kept the same circumstances (Federal Register).
• Auditor procurement still follows the procurement standards, still asks for the audit organization's peer review report, and still weighs experience, staff, quality control reviews and price (2 CFR 200.509(a)).
• An auditor who prepares the indirect cost proposal still cannot also perform the audit when indirect costs recovered in the prior year exceeded $1 million; OMB says it did not change that figure (2 CFR 200.509(b)).
• Major programs are still chosen with a risk-based approach that considers current and prior audit experience, federal and pass-through oversight, and the inherent risk of the program. OMB says it did not propose significant changes to 200.518 other than the Type A table and minor clarifications (2 CFR 200.518(a)).
• The auditee still prepares a summary schedule of prior audit findings and a corrective action plan (2 CFR 200.511(a)).

How can you check the changes yourself?

Read the Federal Register document for what OMB changed and why, and read the eCFR for the text in force today. The eCFR shows the current text and, through its date selector and API, the text as of an earlier date.

• The Federal Register document: Guidance for Federal Financial Assistance, 89 FR 30046, also available as the GPO PDF.
• The current rule text: 200.501, 200.518, 200.512, 200.414 and 200.1.
• Check the date: the text read for this guide was the eCFR as of November 12, 2026, and Title 2 can be amended again.

For where these thresholds sit in a nonprofit's year, see the single audit deadline guide and the Uniform Guidance glossary entry.
