DEFINITION:

An external audit is an independent, third-party review of a nonprofit’s financial statements to ensure accuracy and compliance.
An external audit is an independent examination of a nonprofit’s financial statements and accounting records by a certified public accountant (CPA) or external audit firm. The primary objective is to assess whether the organization’s financial reports are accurate, complete, and in accordance with generally accepted accounting principles (GAAP) or other relevant standards. The auditor evaluates internal controls, tests transactions, and issues an opinion on the fairness of the financial statements. For nonprofits, an external audit may be required by funders, regulators, or bylaws, and it can help demonstrate transparency, accountability, and financial stewardship to stakeholders.

Key Takeaways

  • Conducted by independent auditors
  • Verifies accuracy of financial statements
  • Often required for grants or compliance
  • Supports transparency and donor trust

Why It Matters

External audits build trust, ensure compliance, and help nonprofits identify areas for financial improvement.

Real World Example

A local animal rescue nonprofit receives a large government grant, which requires an external audit of the organization’s financial statements. The nonprofit engages a CPA firm to perform the audit. The auditors review all financial records, evaluate internal controls, and test a sample of transactions. After their review, the auditors issue an unqualified opinion, confirming that the nonprofit’s financial statements fairly present its financial position. This audit report not only satisfies the grant’s requirements but also reassures donors and the board that the organization is managing funds responsibly.
