Performing Single Audits of Federal Awards Under Uniform Guidance

How Single Audits combine financial statement audits, Yellow Book reporting, SEFA procedures, and major-program compliance testing for federal awards.

A Single Audit is a federal-award audit framework for nonfederal entities that expend federal awards above the applicable threshold. It combines a financial statement audit with compliance testing over major federal programs.

For current-period exam study, treat the threshold as period-sensitive. For fiscal years beginning on or after October 1, 2024, the Single Audit threshold is generally $1,000,000 of federal awards expended. For earlier fiscal years, the prior $750,000 threshold may still be relevant.

Single Audit Purpose

Single Audits are designed to give federal agencies, pass-through entities, and other users a coordinated audit over financial statements and federal-award compliance. Instead of separate audits for every award, the auditor uses a risk-based approach to select major programs for compliance testing.

Component Purpose
Financial statement audit Determine whether the entity’s financial statements are fairly presented.
Yellow Book reporting Report on internal control over financial reporting and compliance matters required by Government Auditing Standards.
SEFA procedures Report whether the Schedule of Expenditures of Federal Awards is fairly stated in relation to the financial statements.
Major-program compliance audit Test whether major programs complied with direct and material compliance requirements.
Findings and questioned costs Communicate significant compliance and control issues.

The Single Audit does not audit every transaction in every federal program. It focuses detailed compliance testing on major programs.

Threshold and Applicability

The threshold is based on federal awards expended during the fiscal year, not federal awards received, budgeted, or promised.

Fiscal-year timing General threshold
Fiscal years beginning before October 1, 2024 $750,000 of federal awards expended
Fiscal years beginning on or after October 1, 2024 $1,000,000 of federal awards expended

The entity may be a recipient, subrecipient, and contractor at the same time. Federal awards expended as a recipient or subrecipient count for Single Audit purposes. Payments for ordinary goods or services as a contractor generally do not count as federal awards expended.

Major Programs

The auditor does not test all programs equally. Uniform Guidance uses a risk-based approach to identify major programs.

Major-program selection considers:

  • Size of the program.
  • Type A and Type B program classification.
  • Prior audit findings.
  • Program complexity.
  • Newness of the program.
  • Oversight by federal agencies or pass-through entities.
  • Whether the auditee qualifies as low risk.

Once a program is selected as major, the auditor tests compliance requirements that could have a direct and material effect on that program.

Common Compliance Requirements

The auditor uses the applicable program rules and compliance requirements. Common categories include:

Requirement What the auditor tests
Activities allowed or unallowed Whether the award paid only for permitted activities.
Allowable costs Whether costs were allowable, allocable, reasonable, and documented.
Cash management Whether drawdowns and cash balances complied with award rules.
Eligibility Whether beneficiaries, participants, or subrecipients met program criteria.
Period of performance Whether costs were incurred within the authorized period.
Procurement Whether purchases followed required procurement rules.
Reporting Whether required reports were accurate, complete, and timely.
Subrecipient monitoring Whether the auditee properly monitored subrecipients.

The exam frequently uses allowable costs, eligibility, procurement, reporting, period of performance, and subrecipient monitoring fact patterns.

SEFA and Reporting Package

The Schedule of Expenditures of Federal Awards, or SEFA, lists federal awards expended by program and other required identifying information. The auditor reports on whether the SEFA is fairly stated in relation to the financial statements as a whole.

Reporting element What it communicates
Financial statement opinion Opinion on the financial statements.
Yellow Book report Internal control over financial reporting and compliance matters.
Major-program compliance opinion Opinion on compliance for each major program.
Internal control over compliance report Significant deficiencies and material weaknesses in compliance controls.
Schedule of findings and questioned costs Audit findings, questioned costs, and required detail.
Summary schedule of prior audit findings Status of prior findings.
Corrective action plan Management’s plan to correct current findings.

The auditee, not the auditor, is responsible for preparing the corrective action plan.

Questioned Costs and Findings

Questioned costs arise when the auditor identifies costs that may be unallowable, inadequately supported, or otherwise inconsistent with award requirements.

Issue Possible finding
Missing documentation for payroll charged to a grant Questioned cost and control finding.
Cost incurred after the period of performance Noncompliance and questioned cost.
Procurement did not follow required competition rules Compliance finding, possible questioned cost.
Subrecipient monitoring not performed Internal control over compliance finding.
Prior finding not corrected Repeat finding and follow-up issue.

Not every finding has a known dollar amount. When questioned costs are unknown or not reported, the auditor explains the issue as required by the reporting framework.

Exam Traps

  • The threshold is based on awards expended, not awards received.
  • The threshold is period-sensitive: $1,000,000 for fiscal years beginning on or after October 1, 2024; $750,000 may apply to earlier periods.
  • The SEFA is not the same as the financial statements.
  • Major-program testing is risk-based; not every federal program receives full compliance testing.
  • Single Audit includes both financial statement audit work and major-program compliance work.
  • The corrective action plan is management’s responsibility.
  • Contractors are not automatically treated as subrecipients.

Quick Review

Use this sequence for Single Audit questions:

  1. Determine whether federal awards were expended above the applicable threshold.
  2. Identify whether the entity is a recipient, subrecipient, or contractor.
  3. Recognize the financial statement audit plus major-program compliance audit structure.
  4. Identify the SEFA and in-relation-to reporting.
  5. Apply risk-based major-program selection.
  6. Classify findings, questioned costs, and corrective-action responsibilities.
