When Is a Single Audit Required Under Federal Rules?

A federal grant award amount is not, by itself, the answer. The question of when is single audit required turns on the amount of federal awards your organization expends during its fiscal year, not simply the amount awarded, received, or still sitting in restricted cash. For boards and finance leaders, that distinction can determine whether the organization needs a major-program compliance audit, a detailed Schedule of Expenditures of Federal Awards, and a formal corrective-action process.

When Is a Single Audit Required?

Under the Uniform Guidance at 2 CFR Part 200, a nonfederal entity generally must obtain a Single Audit when it expends $1 million or more in federal awards during a fiscal year. This threshold applies to fiscal years beginning on or after October 1, 2024.

For fiscal years that began before October 1, 2024, the prior threshold of $750,000 generally applies. This transition point matters for organizations with June 30, December 31, or other non-calendar fiscal year ends. The applicable threshold is determined by the start of the organization’s fiscal year, not the date the audit fieldwork begins or the date the reports are issued.

A Single Audit is not merely an audit of financial statements. It combines an audit of the organization’s financial statements, when required by the applicable audit approach, with testing of compliance requirements and internal controls for federal programs selected as major programs. The objective is to provide federal agencies and pass-through entities with assurance that federal funds were administered in accordance with applicable requirements.

Which Organizations Are Subject to the Requirement?

The requirement generally applies to nonfederal entities receiving federal assistance, including nonprofit organizations, state and local governments, school districts, charter schools, institutions of higher education, and tribal entities. A human-services nonprofit administering federal pass-through funding, a municipality receiving infrastructure or emergency-management funds, and a housing organization operating federally supported programs may all be subject to the same overarching Uniform Guidance framework.

Federal funds do not have to come directly from a federal agency. Awards passed through a state agency, county, city, school district, university, or other intermediary count toward the threshold when the underlying funding is federal. The pass-through entity should identify the federal award information, including the Assistance Listings number, award name, federal agency, and applicable compliance requirements.

For-profit entities are not automatically subject to the Uniform Guidance Single Audit requirement in the same way as nonprofits and governmental entities. However, a federal agency, pass-through entity, lender, or program agreement may impose separate audit, reporting, or agreed-upon-procedures requirements. Management should read the award agreement rather than assume that an entity’s tax status resolves the issue.

Federal Awards Expended Is the Critical Calculation

The calculation is often more technical than leadership teams expect. Federal awards expended must be determined under Uniform Guidance rules and reported on the Schedule of Expenditures of Federal Awards, commonly called the SEFA. A general ledger total labeled “grant revenue” is a starting point, not necessarily the final answer.

For cost-reimbursement grants, expenditures often track allowable costs incurred during the fiscal year. For advances, the timing may differ from cash receipt. Noncash assistance can also be included. Food commodities, donated property, vaccines, and similar assistance may need to be valued and reported under the applicable program rules.

Loan and loan-guarantee programs require particular care. In some cases, the outstanding balance of federal loans may be treated as federal awards expended for the year, even when the organization did not receive new loan proceeds during that period. HUD-related activity, affordable-housing development, and other federally financed programs can create reporting issues that are not apparent from operating expenses alone.

Organizations should also account for program clusters. Several awards may be grouped as one cluster for major-program determination, which can affect the audit scope even if each individual award appears modest. Medicaid, student financial assistance, research and development, and certain workforce or nutrition programs can involve cluster rules or program-specific compliance considerations.

Direct Awards, Subawards, and Contractor Payments

The distinction between a subrecipient and a contractor is central to the calculation. A subrecipient carries out part of a federal program and is accountable for programmatic results. Its federal expenditures may count toward its own Single Audit threshold. A contractor provides goods or services for the organization’s use and is generally not subject to the same federal award compliance responsibilities for that payment.

Labels in an agreement are not controlling. Finance leaders should assess the substance of the relationship: Who determines program eligibility? Who has responsibility for performance measures? Who makes programmatic decisions? Who bears responsibility for compliance? A pass-through entity must make and document this determination because it affects monitoring obligations as well as the recipient’s audit analysis.

What Happens Once the Threshold Is Met?

Crossing the threshold requires more than engaging an auditor late in the year. The organization must prepare a complete SEFA, identify applicable federal programs and awards, and maintain support for the amounts reported. The auditor uses that information to determine major programs based on risk and expenditure criteria.

For each major program, the audit evaluates compliance with applicable requirements and tests internal controls over compliance. Depending on the program, this may include allowable costs, eligibility, reporting, procurement, matching, period of performance, special tests and provisions, or subrecipient monitoring. The precise scope depends on the federal program and the current Compliance Supplement.

The audit reports may include findings when the auditor identifies material weaknesses, significant deficiencies, material noncompliance, questioned costs, or other reportable matters. A finding is not automatically evidence of misuse or fraud. It is, however, a governance matter that deserves prompt, documented attention. Management is required to prepare a corrective action plan for current-year findings and address the status of prior audit findings when applicable.

Federal audit reporting is generally due to the Federal Audit Clearinghouse within the earlier of 30 calendar days after receipt of the auditor’s reports or nine months after fiscal year-end. Missing the deadline can create complications with federal agencies and pass-through funders, including heightened monitoring, delayed awards, or concerns during grant renewal.

A Financial Statement Audit Does Not Replace a Single Audit

A common misunderstanding is that a conventional nonprofit or governmental financial statement audit satisfies the federal requirement. It does not. Financial statement audits address whether the financial statements are fairly presented under the relevant accounting framework. A Single Audit adds federal compliance testing, internal-control testing over compliance, SEFA reporting, and required reporting to federal authorities.

The reverse can also be true: an organization below the Single Audit threshold may still need a financial statement audit because of state law, a financing agreement, a charter authorizer, a HUD requirement, a board policy, or a funder condition. A housing entity, school, or organization with significant borrowing may have multiple audit obligations that overlap but are not interchangeable.

How to Prepare Before Year-End

The strongest Single Audits begin before the audit starts. Management should maintain a grant inventory that identifies each federal award, funding source, Assistance Listings number, pass-through award number, period of performance, compliance contacts, and whether the award is direct or passed through another entity. This inventory should be reconciled regularly to the general ledger and grant drawdowns.

The organization should also assign clear ownership for SEFA preparation. Grant managers often understand program operations, while finance personnel control the accounting records. Both perspectives are necessary. A reliable SEFA requires coordination around reimbursements, advances, indirect-cost treatment, subawards, noncash assistance, and the timing of expenditures.

Internal controls should be documented in a way that reflects actual practice, not an idealized policy manual. If one person reviews reimbursement requests, approves drawdowns, monitors subrecipients, and submits federal reports, management should recognize the segregation-of-duties risk and establish compensating oversight. Board treasurers and audit committees should ask whether controls are operating consistently, especially as staffing changes or federal programs expand.

For organizations near the threshold, a quarterly federal-expenditure forecast is often worthwhile. It gives leadership time to budget for the engagement, assemble grant documentation, resolve coding issues, and select an audit firm with deep regulatory fluency in the organization’s programs. Goldenthal & Suss approaches this work as an accountability engagement for management and the board, not a year-end reporting exercise.

The most useful next step is to calculate federal awards expended now, using your fiscal-year start date and a grant-by-grant inventory. If the total is near or above the applicable threshold, bring the calculation, the draft SEFA, and the status of key controls to your audit committee before year-end. That conversation can provide the clearest picture your board will ever get of where federal compliance stands before it becomes an audit finding.
