IRS Audits of Tax-Exempt Organizations: What to Expect

Tax-exempt organizations are subject to IRS examination authority under 26 U.S.C. § 7602, which grants the agency broad power to examine books, records, and activities of any entity claiming federal tax-exempt status. An audit can result in revocation of exemption, assessment of taxes on unrelated business income, imposition of excise taxes, or intermediate sanctions against disqualified persons. Understanding how the IRS selects organizations, conducts examinations, and reaches conclusions helps boards, officers, and legal counsel respond effectively.

Definition and Scope

An IRS examination of a tax-exempt organization is a formal review of whether the organization continues to qualify for the exemption it holds, whether it has met all applicable filing obligations, and whether any transactions give rise to tax liability. The IRS Tax Exempt and Government Entities (TE/GE) division administers these examinations through its Exempt Organizations (EO) unit (IRS TE/GE Division).

The scope of an examination can be narrow or comprehensive:

• Correspondence audit — conducted entirely by mail, typically focused on a single line item or specific issue flagged on Form 990.
• Office audit — the organization's representative meets with an IRS examiner at a local IRS office; limited in scope.
• Field examination — an IRS revenue agent conducts an on-site review of the organization's premises, books, contracts, and internal governance records; the broadest form of examination.

The TE/GE unit published data showing it closed approximately 4,700 exempt organization examinations in fiscal year 2022 (IRS FY 2022 Data Book, Table 25). Of those, a significant fraction resulted in revocations, agreed changes, or referrals to other IRS functions.

Examination authority draws on 26 U.S.C. § 6201 for assessment and § 7602 for the summons and examination powers within Subtitle F of the Internal Revenue Code. Organizations exempt under § 501(c)(3) face the most detailed scrutiny because donors claim charitable deductions tied to the organization's continued qualified status.

How It Works

The IRS examination process for exempt organizations follows a structured sequence:

1. Selection — The IRS EO unit identifies the organization through a compliance check, Form 990 review, information return discrepancy, referral from another federal or state agency, or a third-party complaint. Random statistical sampling is also used as a selection method.
2. Initial contact — The organization receives a written notice identifying the type of examination, the tax years under review, and the name of the assigned revenue agent or tax examiner.
3. Information document request (IDR) — The examiner issues an IDR listing the documents required: meeting minutes, contracts, compensation records, financial statements, grant files, and governance policies. Response deadlines are typically 30 days from issuance.
4. Review and interviews — The examiner reviews submitted documents and may conduct interviews with officers, directors, or employees. For field examinations, on-site visits assess whether the organization's actual activities match its stated exempt purpose.
5. Proposed adjustments — If issues are identified, the examiner issues a report of proposed changes. The organization has the right to respond to proposed changes before a final determination is made.
6. Resolution — The examination closes in one of three ways: no change (no issues found), agreed change (the organization accepts adjustments), or unagreed change (the organization contests findings and may appeal).

An organization that disagrees with the examiner's conclusions may request consideration by the IRS Independent Office of Appeals, which provides an administrative review independent of the TE/GE examination function. This step is available before the IRS issues a final adverse determination.

Maintaining comprehensive records as described in tax-exempt recordkeeping requirements substantially reduces examination risk and shortens the duration of any examination that does occur.

Common Scenarios

Five examination scenarios account for the majority of TE/GE referrals and closures:

Private inurement and excess benefit transactions — An examiner reviewing compensation paid to a founder, executive, or related party will apply the rebuttable presumption procedure under 26 U.S.C. § 4958. If the board failed to document contemporaneous comparability data or obtain approval from disinterested directors, excise taxes of 25% (first tier) or 200% (second tier) of the excess benefit can apply to the disqualified person. More detail on this issue appears at private inurement and excess benefit transactions.

Unrelated business income tax (UBIT) — Organizations that operate trades or businesses unrelated to their exempt purpose may owe corporate income tax on net unrelated business income at standard rates under 26 U.S.C. §§ 511–514. Examiners look for advertising revenue, rental income from debt-financed property, and services sold to non-members. The UBIT framework is covered at unrelated-business-income-tax-ubit.

Political activity — A § 501(c)(3) organization is absolutely prohibited from participating or intervening in any political campaign on behalf of or in opposition to any candidate for public office (IRC § 501(c)(3)). Examiners review social media posts, newsletters, and event records when a referral alleges political activity.

Nonfiling or incomplete Form 990 — An organization that fails to file a required annual return for 3 consecutive years automatically loses its exempt status under IRC § 6033(j). Examiners also flag materially incomplete returns — particularly schedules covering compensation, foreign activities, and governance.

Lobbying limit violations — Public charities that elect the expenditure test under § 501(h) face a 25% excise tax on lobbying expenditures that exceed the applicable ceiling, and loss of exemption if excess lobbying is substantial (IRC § 4911). See lobbying-rules-for-tax-exempt-organizations for a breakdown of the § 501(h) election and the no-substantial-part test.

Decision Boundaries

The outcome of an examination turns on two primary legal questions: (1) whether the organization continues to qualify for the exemption it claims, and (2) whether specific transactions created a separate tax liability without affecting overall exempt status.

Revocation vs. excise tax — Not every audit finding leads to revocation. If the problematic activity is isolated — for example, a single excess benefit transaction — the IRS may impose § 4958 excise taxes on the disqualified person and require a correction without revoking the organization's § 501(c)(3) status. Revocation is more likely when the prohibited activity reflects the organization's ongoing operations, such as consistent political campaign intervention or systemic private inurement benefiting insiders over multiple years.

Public charity vs. private foundation distinctions — Private foundations face stricter self-dealing rules under 26 U.S.C. § 4941, mandatory distribution requirements under § 4942, and excess business holdings limits under § 4943. An examiner reviewing a private foundation will apply a different penalty matrix than one reviewing a public charity. The public-charity-vs-private-foundation classification therefore shapes the entire examination risk profile.

Agreed vs. unagreed closures — If the organization and the examiner reach an agreed resolution, the organization signs Form 6018 (Consent to Proposed Adverse Action) or Form 872 (Consent to Extend Time to Assess Tax) depending on the issue type. An unagreed case proceeds to the IRS Appeals Office and, if unresolved there, to the United States Tax Court or a federal district court. Appeal rights are grounded in 26 U.S.C. § 7442 (Tax Court jurisdiction) and are preserved only if the organization does not sign a closing agreement at the examiner level.

Organizations that have had exemption revoked and seek to restore it should consult reinstating-revoked-tax-exempt-status for the procedural pathway, which requires a new exemption application and, for automatic-revocation cases, payment of the applicable user fee.
