The Single Audit Threshold Just Jumped to $1 Million: What Every Growing Nonprofit Needs to Know

For 27 years, the number was $750,000. Any nonprofit, tribal government, or state agency that spent more than $750,000 in federal awards in a fiscal year triggered a Single Audit — the comprehensive, expensive, and often dreaded federal compliance review that goes far beyond a standard financial statement audit. The threshold was set in 1997 and never adjusted, not for inflation, not for the explosion in federal grant spending that followed the American Rescue Plan, and not for the thousands of small organizations that found themselves subject to audit requirements designed for entities operating at a completely different scale.

That changed on October 1, 2024, when the revised 2 CFR Part 200 Uniform Guidance raised the Single Audit threshold to $1 million. The first audits under the new threshold are being filed now, for fiscal years ending September 30, 2025, and later. For organizations spending between $750,000 and $999,999 in federal funds, the audit burden just disappeared. For organizations approaching or crossing the $1 million line, the compliance landscape just shifted in ways that require immediate attention.

What the Single Audit Actually Requires — and Why the Threshold Matters

A Single Audit is not a financial audit with a few extra steps. It is a fundamentally different engagement that tests whether an organization has complied with the specific requirements attached to every federal program from which it received funds. Auditors must evaluate internal controls over federal programs, test transactions for compliance with program-specific rules, identify major programs based on risk assessment and dollar thresholds, and report findings in a format prescribed by the OMB Compliance Supplement — a document that runs to hundreds of pages and changes annually.

The cost reflects this complexity. A standard financial statement audit for a nonprofit spending $800,000 in federal funds might cost $15,000 to $25,000. Add a Single Audit, and the engagement typically runs $30,000 to $60,000 or more, depending on the number of federal programs and the complexity of compliance requirements. For organizations operating on thin margins — which describes most nonprofits in the $750,000 to $1 million federal spending range — that incremental cost consumed resources that could have gone to program delivery.

The 33% threshold increase means that organizations spending less than $1 million in federal awards are no longer required to commission a Single Audit. They still must follow all Uniform Guidance requirements — procurement standards, subrecipient monitoring, time-and-effort reporting, allowable cost principles — but they are relieved of the formal audit requirement that verifies compliance through independent testing.

Who Benefits Immediately

The organizations that benefit most are those in the $750,000 to $999,999 federal expenditure band. This population is larger than most people realize. During the pandemic-era funding surge, thousands of community-based nonprofits, rural health clinics, tribal organizations, and small local governments crossed the old threshold for the first time — often because they accepted a single large CARES Act or ARPA sub-award on top of their existing federal grants. Many of these organizations had never undergone a Single Audit before and scrambled to find qualified auditors in a market where Single Audit expertise was already scarce.

For these entities, the threshold increase provides immediate financial relief. An organization that spent $850,000 in federal funds in its fiscal year ending December 31, 2025 — where all awards were issued after October 1, 2024 — falls below the new threshold and can revert to a standard financial statement audit. The savings of $15,000 to $35,000 per year represents real operational capacity.

Community action agencies, Head Start grantees, Federally Qualified Health Centers with smaller HRSA awards, tribal housing authorities, and rural school districts with Title I pass-through funding are among the entity types most likely to fall in this band.

The Transition Is More Complicated Than It Appears

The relief is real but not automatic. The new threshold applies to federal awards issued on or after October 1, 2024. Awards issued before that date remain subject to the old $750,000 threshold. This creates a dual-compliance environment that will persist through at least 2026 for organizations with multi-year grants that straddle the effective date.

Here is how it works in practice: suppose a nonprofit has two active federal awards. One is a three-year grant issued in September 2024 (old guidance applies — $750,000 threshold). The other is a new cooperative agreement issued in January 2025 (new guidance — $1 million threshold). If the organization spends a combined $900,000 in federal funds, it may still trigger a Single Audit based on the older award's threshold, even though it falls below the new $1 million line.

The OMB's guidance recommends maintaining a tracking schedule of awards by issue date to identify which version of the Uniform Guidance applies to each. In practice, this means your finance team needs to tag every federal award with its effective guidance version and calculate expenditure thresholds separately. Most accounting systems do not do this out of the box. Organizations that fail to track properly risk either paying for unnecessary audits or — worse — skipping audits they are still legally required to complete.

What Changes Beyond the Threshold Number

The Single Audit threshold increase was part of a broader 2 CFR 200 overhaul — the most significant revision since the Uniform Guidance was originally issued in 2013. Several other changes landed simultaneously and affect organizations at every spending level.

De minimis indirect cost rate increased from 10% to 15%. Organizations that lack a federally negotiated indirect cost rate can now recover 15% of modified total direct costs as indirect expenses. For a nonprofit spending $500,000 in direct costs on a federal program, this change adds $25,000 in recoverable overhead — often the difference between sustainable operations and subsidizing federal programs from unrestricted funds.

Procurement thresholds increased. The simplified acquisition threshold and micro-purchase threshold both rose, reducing the number of purchases that require competitive bidding documentation. This is a practical relief for program staff who previously needed three quotes to buy a $5,000 piece of equipment.

Subrecipient monitoring requirements strengthened. Pass-through entities now face expanded documentation expectations for monitoring their sub-awardees, including more explicit risk assessment frameworks and follow-up protocols for findings. If you receive federal funds as a sub-recipient, expect your pass-through entity to request more documentation than before.

Equipment and real property rules clarified. The revised guidance provides clearer standards for when equipment purchased with federal funds can be used on other projects and what happens to property when a grant closes. These changes resolve ambiguities that had generated audit findings for years.

A Compliance Roadmap for Organizations Near the Threshold

Whether you just escaped the Single Audit requirement or you are approaching it for the first time, the threshold change demands a recalibration of your compliance infrastructure.

If you dropped below the new threshold: Celebrate the cost savings, but do not dismantle your compliance systems. You are still bound by every Uniform Guidance requirement — allowable costs, time-and-effort documentation, procurement standards, conflict of interest policies, and subrecipient monitoring. Federal agencies can still audit you directly at any time, and your pass-through entities may have their own monitoring requirements that exceed the Uniform Guidance minimums. The Single Audit was the verification mechanism, not the compliance obligation itself.

If you are between $750,000 and $1 million and growing: This is the critical planning window. If your organization is on a trajectory to cross $1 million in federal expenditures within the next one to two fiscal years, invest in audit readiness now — before it is required. Engage an auditor with Single Audit experience for your standard financial statement audit so they understand your systems before the stakes increase. Build your Schedule of Expenditures of Federal Awards (SEFA) even if you do not yet need it for audit purposes. Document your internal controls over federal programs in writing.

If you just crossed $1 million: Your first Single Audit will scrutinize systems that may never have been formally tested. The most common first-time findings involve procurement documentation (missing or insufficient competitive bidding records), time-and-effort reporting (employees working on multiple programs without adequate allocation methodology), and subrecipient monitoring (passing federal funds to sub-awardees without formal risk assessment or oversight protocols). Address these areas before your auditor arrives.

Regardless of threshold status: Take advantage of the increased de minimis indirect cost rate. If you have been recovering 10%, update your budget templates and grant proposals to reflect 15%. This is free money for organizations that qualify, and many leave it on the table simply because their templates have not been updated.

The Bigger Picture: Why These Changes Signal a Shift in Federal Grant Oversight

The threshold increase and the broader 2 CFR 200 revision did not happen in a vacuum. They arrived alongside Executive Order 14332 ("Improving Oversight of Federal Grantmaking"), which mandates enhanced interagency coordination, outcome-driven performance monitoring, and expanded agency discretion to modify, pause, or terminate awards. The 2025 OMB Compliance Supplement introduced refined audit procedures, expanded documentation expectations, and strengthened internal control frameworks.

Read together, these changes describe a federal grant ecosystem that is simultaneously reducing procedural burden on smaller organizations and increasing substantive accountability across the board. The Single Audit threshold went up — but so did expectations for how every grantee documents outcomes, manages sub-awards, and demonstrates alignment with federal priorities.

For growing nonprofits navigating this landscape, the challenge is building compliance capacity that scales with your federal portfolio without consuming the resources you need for mission delivery. Tools like Granted can help you identify the right funding opportunities and build proposals that account for these evolving requirements from the start.
