Nonprofit Audit Requirements

When Does Your Nonprofit Need an Audit?

Audit requirements for nonprofits vary by state, revenue threshold, and funding source. Here are the most common triggers that require your organization to undergo a formal audit.

State Revenue Thresholds

Most states require a nonprofit audit when annual revenue crosses a set threshold — typically ranging from $250,000 to $750,000. Organizations registered in multiple states must meet each state's individual standards.

Federal Grant Requirements

Nonprofits receiving $750,000 or more in federal awards annually must undergo a Single Audit under OMB Uniform Guidance (2 CFR Part 200), regardless of state-level requirements.

Private Funder Requirements

Many foundations and major donors require audited financial statements as a condition of funding. An audit demonstrates the financial transparency and accountability your funders expect.

Board-Mandated Audits

Good governance practices often lead nonprofit boards to require annual audits voluntarily — establishing credibility with stakeholders even when not legally mandated.

Yellow Book Standards

Government-funded nonprofits and those subject to Generally Accepted Government Auditing Standards (GAGAS / Yellow Book) require auditors with specialized governmental audit training and credentials.

Grant-Specific Requirements

Individual grant agreements frequently include audit requirements regardless of revenue size. Review every active grant agreement to identify any engagement-specific audit obligations.

Common Questions

Nonprofit Audit FAQ

Do nonprofits need an audit every year?
Not every nonprofit requires an annual audit. Requirements vary based on state law, revenue thresholds, and funding sources. Some states mandate audits when annual revenue crosses a set threshold, and federal grant agreements often require audited financial statements regardless of state rules. Review your state requirements and grant terms to confirm your specific obligation.
What are the nonprofit audit requirements by state?
Nonprofit audit requirements vary significantly by state. Most states set revenue thresholds ranging from $250,000 to $750,000 before requiring a full audit. Organizations registered in multiple states must meet each state's individual standards and comply with any applicable grant-specific audit conditions. Contact us for a review of your specific state obligations.
When does a nonprofit need a single audit?
A nonprofit needs a single audit when it expends $750,000 or more in federal awards in a single fiscal year. This threshold is set by OMB Uniform Guidance (2 CFR Part 200). The single audit includes a financial statement audit plus compliance testing of major federal programs.
What does a nonprofit audit checklist include?
A nonprofit audit checklist typically covers board-approved financial statements, general ledger detail, bank reconciliations, grant agreements, IRS Form 990, payroll records, fixed asset schedules, and prior-year audit reports. Organizing these documents before fieldwork begins reduces delays and keeps the audit on schedule.
How much does a nonprofit audit cost?
Nonprofit audit cost depends on organizational size, revenue volume, number of funding streams, and the complexity of grant compliance requirements. Audits for smaller nonprofits with straightforward structures typically cost less due to lower transaction volume. Contact us for a no-obligation quote based on your organization's specific profile.
Who audits nonprofit organizations?
Nonprofit organizations are audited by independent licensed CPA firms with experience in nonprofit financial reporting and compliance. Auditors must maintain GAAS independence standards throughout the engagement. Summit Advisory performs these engagements directly — every report we issue is one our team prepared, with no referrals or third-party involvement.
