When does a nonprofit need an audit? Federal and state requirements

You probably know Form 990 is part of your annual filing rhythm. What's easier to miss: audit, review, and financial statement requirements that may apply depending on your funding, activities, state registrations, and fiscal year.

For some organizations, the relevant questions come from federal award rules. For others, they come from state charitable registration or reporting requirements. In some cases, both apply.

Don't treat one filing or audit as a substitute for every other requirement. Confirm what applies, document the answer, and make sure your finance team can support the work when a CPA or advisor needs the records.

At Ramp, we help nonprofit finance teams with the operational side of readiness — organized transaction records, receipt documentation, approval workflows, expense coding, reconciliation support, and cleaner reporting workflows. This guide walks the landscape so you know what to discuss with your CPA, auditor, or legal advisor.

Federal award audits: The Single Audit question

If your organization expends federal awards, you may need to evaluate whether Single Audit rules apply for the relevant fiscal year. Current 2 CFR 200.501 sets the audit threshold at $1,000,000 or more in federal awards expended during the year.

The Federal Audit Clearinghouse notes the threshold was $750,000 for fiscal years starting before October 1, 2024 and $1,000,000 for fiscal years starting on or after that date (2 CFR 200.501; FAC Audit Submission Guide).

That threshold is based on federal awards expended, not total organizational revenue. A nonprofit with significant overall revenue may not meet the Single Audit threshold if federal expenditures are below the applicable amount. A smaller organization with substantial federal award activity may still need a closer review.

The details are fact-specific. You'll want to confirm the fiscal year at issue, whether funds came directly from a federal agency or through a pass-through entity, how awards are classified, and which expenses belong on the Schedule of Expenditures of Federal Awards. Those are good questions for a CPA firm that understands nonprofit and federal award work.

What Single Audit preparation usually requires

A Single Audit isn't just a standard year-end audit with a different name. It combines financial statement audit work with testing related to federal award compliance.

In practice, you may need clean records for award spending, approvals, cost allocation, procurement, program coding, and reporting support. Those records help the auditor understand how federal funds were used.

The Federal Audit Clearinghouse is the submission point for federal grant audits. Reporting packages are due by the earlier of 30 calendar days after you receive the auditor's report or nine months after the end of the audit period under 2 CFR 200.512 (FAC Audit Submission Guide; 2 CFR 200.512). If your timing is tight, plan early with your audit firm rather than waiting until after year-end close.

State audit and review requirements vary

State-level requirements are separate from federal award rules. They often come through charitable registration, solicitation, or nonprofit reporting frameworks. The exact requirement varies by state and may depend on revenue, contributions, registration status, exemptions, professional fundraiser use, and the type of financial statement support required.

The differences aren't academic. The table below summarizes how three states structure their requirements — but because each state defines and administers these rules differently, confirm the current thresholds and any applicable exemptions with your CPA or state charitable registration office.

• Illinois thresholds reflect the 2024 amendment (effective January 1, 2024). The paid professional fundraiser audit trigger was not changed by that amendment.

Because states define and administer these requirements differently, don't rely on a single rule of thumb if you're operating nationally or soliciting in multiple states. Maintain a state-by-state tracker that notes the source, effective date, threshold metric, exemptions, filing deadline, extension process, and the last review date.

Form 990 timing is only one part of the calendar

Form 990 deadlines are useful planning anchors, but they don't answer every audit or state filing question. The IRS sets annual exempt organization returns by your tax year end.

The due-date table shows May 15 for December 31 year-end organizations, November 15 for June 30 year-end organizations, and February 15 for September 30 year-end organizations, with extended dates varying by year end (IRS annual return due date guidance).

State filing deadlines, audit fieldwork timelines, board review, and Single Audit submission timing may follow different calendars. The practical question for your team: when will your CPA need clean books, reconciliations, documentation, approval records, grant coding, and financial statements to complete the work on time?

Questions to confirm before audit season

Before close gets busy, your finance team should confirm:

• Federal award exposure: Did you expend federal awards during the fiscal year, and if so, what threshold applies?
• Pass-through funding: Did federal funds come through another entity, and how should those amounts be identified and documented?
• State registration footprint: Where are you registered, soliciting, or otherwise subject to charitable reporting requirements?
• State trigger metric: Does the relevant state use total revenue, contributions, gross annual contributions, assets, or another metric?
• Review versus audit: Does the state require a review, audit, compilation, or other financial statement support?
• Exemptions and special rules: Are there exemptions, professional fundraiser rules, religious organization rules, government grant exclusions, or other state-specific factors to confirm?
• CPA readiness: Did you engage a CPA firm early enough to plan scope, timing, documentation, and board review?
• Record organization: Are your transactions, receipts, approvals, reconciliations, grant codes, and expense allocations organized for efficient CPA review?

These questions aren't a substitute for legal, tax, or audit advice. They're a starting point for a conversation with your CPA, auditor, or legal advisor.

How to prepare the finance operation

Whether you're facing a federal Single Audit, a state financial statement audit, a state financial review, or routine year-end reporting, the operational foundation is similar. You'll need clean books, current reconciliations, accessible supporting documentation, clear approval history, and consistent coding by program, grant, department, or cost center.

That work is easier when it happens throughout the year. Receipts attached at the time of purchase, approvals captured before spend occurs, and expenses categorized as transactions happen will reduce your year-end scramble. They also give your finance team a clearer record set to share with the CPA.

How Ramp helps

Ramp helps nonprofit finance teams keep spend records organized throughout the year. You can capture receipts and transaction documentation as spending happens, categorize expenses by program, grant, department, or cost center, and use approval workflows to document how spend was reviewed.

Ramp doesn't determine which audit, tax, legal, or compliance requirements apply to your organization. What Ramp can support is the financial operations layer underneath that work: cleaner records, better spend visibility, easier reconciliation, and more organized reporting support when your finance team or CPA needs it.
