IRS Audit Triggers for Large Nonprofits: What’s Changed and What to Watch

Most nonprofit executives filing a clean Form 990 assume the risk of an IRS examination is low. In many cases that assumption holds. The IRS has increasingly shifted to data-driven, issue-based selection for exempt organization examinations. Public reports and IRS program materials describe greater reliance on analytics and specialized tools to identify returns with higher indicators of noncompliance, often before a case reaches an examiner. If your 990 looks unusual relative to peer organizations, that inconsistency can be enough to draw IRS attention.

Behind the IRS Selection Process

The IRS has moved to a data-driven, issue-based selection process for exempt organization examinations. According to a GAO report on IRS exempt organization examination practices, the IRS used data to select nearly 70 percent of its Form 990 examinations in fiscal year 2019, with analytical models scoring each return for its likelihood of noncompliance. The IRS has continued building on that approach, developing new data tools, including graph-based analysis, to identify potentially problematic relationships and transactions.

What this means in practice is that your Form 990 is being read twice. Once by whatever preparer touches it, and once by automated screening and analytics that compare your return to peer organizations of similar size, revenue and structure. Discrepancies in functional expense allocations, compensation levels that appear inconsistent with peer organizations and gaps between what your 990 says and what your audited financials show are all the kinds of signals that can push a return higher on the risk-score ranking.

Large nonprofits also tend to have more complex returns, which creates more surface area for inconsistency. Multiple revenue streams, related-party transactions, compensation for senior staff, unrelated business activities and investment income all require careful and consistent reporting. Any one of those areas handled loosely can create a flag worth investigating.

The Areas Examiners Focus On

When the IRS Exempt Organizations Examinations program does open a case, it is typically focused on a few recurring areas: compensation, related-party transactions and unrelated business income.

When it comes to compensation, the IRS wants to see that executive pay was set through an independent process, supported by comparability data from similarly sized organizations and documented by the board at the time the decision was made. That contemporaneous record matters. This is both a governance best practice and a common examination focus area. A board approval mentioned briefly in meeting minutes, with no supporting analysis, is not the same as a properly documented compensation determination. If the records do not show the process, the IRS may act as though the process did not happen.

Related-party transactions carry similar documentation requirements. Any business arrangement involving a board member, officer, key executive, or other insider needs to be fully disclosed, supported by evidence of fair market value and backed by board oversight including conflict-of-interest acknowledgments. The IRS is particularly attentive to whether charitable assets are being used exclusively for exempt purposes, and any arrangement where an insider could benefit is examined carefully.

Unrelated business income remains a frequent compliance issue. IRC Section 512(a)(6) requires nonprofits with more than one unrelated business activity to calculate taxable income separately for each activity rather than netting gains and losses across all of them. If your organization earns income from multiple unrelated sources and is still reporting on a combined basis, that is a compliance issue that needs to be corrected before it becomes an examination issue.

What Your Form 990 Says About Your Organization

The Form 990 is a public document, and the IRS treats it accordingly. Every schedule, every narrative explanation and every number on that return is part of the picture your organization presents to the public and to regulators. Organizations that treat the 990 as a routine annual filing rather than a compliance document tend to leave gaps that examiners notice.

Schedule O explanations deserve more attention than most organizations give them. When something significant is happening in your finances, a vague or incomplete Schedule O explanation is worse than a detailed one. Examiners are trained to look at what is not explained as much as what is. If your narrative does not account for a meaningful change in program expense ratios, an unusual revenue source or a significant transaction with a related party, examiners may assume the worst.

Governance disclosures also factor into examination risk. The IRS asks whether your board reviews the Form 990 before filing, whether you have a written conflict-of-interest policy and whether you monitor compliance with it. An organization that answers yes to those questions but cannot produce documentation supporting those answers is in a worse position than one that answered no honestly. Consistency across disclosures matters.

Get Your House in Order Before a Problem Arises

The most effective audit preparation is not a response to an examination notice. It happens well before that. Organizations that review their Form 990 with the same critical eye as an examiner, maintain detailed documentation for every significant decision and build governance processes that leave a clear paper trail tend to get through examinations faster and with fewer complications.

That means keeping compensation comparability studies on file and updating them regularly. It means board minutes that reflect real deliberation, not just votes. It means making sure your UBIT activities are properly segmented on your 990-T. And it means reviewing your audited financial statements alongside your 990 to confirm the two tell a consistent story before either one is filed.

Internal controls also need to keep pace with organizational size. A nonprofit operating at $10 million or more in annual revenue with limited segregation of duties and minimal approval layers for significant transactions is carrying more examination risk than it likely realizes.

Protect Your Tax-Exempt Status With the Right Support

The compliance picture for large nonprofits has become more demanding over the past several years, and the IRS has built the infrastructure to enforce it. Understanding where the examination risk actually sits, and addressing those areas before they become problems, is the most practical thing a nonprofit leader can do right now.
