24 March 2026 Congressional Research Service issues analysis of private inurement, private benefit and intermediate sanctions applicable to tax-exempt organizations
The Congressional Research Service (CRS) has released a report1 that explains the federal tax standards that prohibit tax-exempt organizations from conferring improper economic or non-economic benefits on private parties. It also details the operation of the intermediate-sanction excise taxes — an increasingly important enforcement tool used by the IRS. This Tax Alert summarizes the key components of the CRS analysis and highlights considerations for IRC Section 501(c)(3) and 501(c)(4) organizations. The CRS report emphasizes that the prohibition on private inurement remains one of the strictest limitations applicable to IRC Section 501(c)(3) organizations. Private inurement applies exclusively to any "private shareholder or individual," which Treas Reg. Section 1.501(a)-1(c) defines as any "persons having a personal and private interest in the activities of the organization," whether through formal titles or practical authority. The rule is absolute, with even a small or isolated instance of inurement being sufficient to jeopardize exempt status. Although the statutory language refers to "net earnings," the IRS and courts have interpreted the concept broadly. In practice, private inurement encompasses the use or transfer of any organizational assets for the excess benefit of an "insider" (typically an organization's board members, officers, employees with significant influence over the organization, and their family members). CRS notes longstanding examples that can give rise to inurement, including unreasonable compensation, loans on advantageous terms, under- or over-valued sales and leases, and personal use of an organization's property. These examples indicate that the concept extends far beyond profit distribution and is embedded in routine operational decisions. While private inurement is narrowly focused on insiders, the prohibition on private benefit is significantly broader and applies to any private party. CRS explains that a violation of this rule occurs when the organization's activities provide a substantial private advantage that is inconsistent with serving public or charitable interests. Unlike the absolute rule for private inurement, some private benefit is permissible if it is necessary and incidental to furthering exempt purposes, meaning it is both qualitatively related to an organization's exempt purposes and quantitatively insubstantial compared to the public benefit achieved. The IRS relies on this distinction frequently, for example, when considering whether fee-for-service activities or targeted programs inadvertently skew benefits toward a discrete group. Both prohibitions — private inurement and private benefit — inform analysis of IRC Section 501(c)(3) exemption qualification under both the organizational and operational tests. If an organization fails to satisfy either test, it does not qualify for tax-exempt status under IRC Section 501(c)(3). IRC Section 501(c)(3) organizations must meet both the organizational and operational tests. The organizational test requires governing documents to restrict activities to those that further exempt purposes, so that the organization's assets remain dedicated to those purposes. The operational test evaluates how an organization conducts itself in practice, meaning it must primarily engage in activities that substantially further its tax-exempt purpose(s). In evaluating operations, the IRS looks not only at the nature and scope of the organization's activities but also at whether benefits the organization provides to private parties — whether insiders or not — are necessary and incidental to furthering its tax-exempt purposes. CRS highlights that case law on private benefit is highly fact specific but consistently emphasizes proportionality; an organization's activities must not materially serve private interests. CRS provides several examples of transactions that have triggered IRS enforcement action. These include excessive or inadequately substantiated compensation arrangements, below-market leases or sales, inappropriate loans and personal use of organizational credit cards or property. The report also notes that some organizations have been found to operate for private or partisan interests when they structure programs for the benefit of specific political groups or members, rather than for the broader community. In addition to revocation, tax-exempt organizations face excise taxes, commonly known as intermediate sanctions, when they provide improper benefits to insiders. CRS provides an extensive comparison of three key excise tax provisions. IRC Section 4958 applies to Section 501(c)(3) public charities and IRC Section 501(c)(4) organizations (note that it does not apply to private foundations). When an economic benefit provided to a "disqualified person" exceeds what the organization receives in return, that person may be subject to a 25% excise tax, with an additional 200% tax if the transaction is not corrected within the allotted time. Organization managers may also be taxed if they knowingly participate in excess benefit transactions. CRS highlights the regulatory rebuttable presumption of reasonableness, which can provide meaningful protection when organizations follow proper procedures (i.e., having an independent board review and approving compensation using reasonable comparability data, then contemporaneously documenting that review and approval process). Supporting organizations face uniquely stringent rules under IRC Section 4958. Transactions between supporting organizations and their substantial contributors (and/or family members and 35% controlled entities of those substantial contributors and their family members), even those with no managerial influence, are automatically treated as excess benefit transactions, meaning the entire amount of the transaction (e.g., grant, loan, compensation) is treated as an excess benefit regardless of reasonableness. CRS underscores that this mechanism reflects heightened congressional concern over potential misuse of supporting organization structures. CRS reiterates that IRC Section 4941 imposes much stricter limits on private foundations. Most direct transactions between a private foundation and its disqualified persons are prohibited outright, subject to an excise tax on the disqualified person of 10% of the amount involved, even if the terms are favorable to the foundation. The excise taxes escalate to 200% of the amount involved if the transaction is not corrected by the time the IRS imposes the 10% tax or mails a notice of deficiency involving the tax, whichever occurs earlier. Only narrow exceptions apply, such as reasonable and necessary compensation for certain personal, professional services. IRC Section 4960, enacted under the 2017 Tax Cuts and Jobs Act, and expanded in 2025, imposes on tax-exempt organizations a 21% excise tax on compensation of any employee in excess of $1 million during a tax year, and on certain parachute payments to employees. Unlike the excise taxes under IRC Sections 4958 and 4941, the IRC Section 4960 excise tax is imposed on the organization itself, not on the recipient of the compensation. CRS emphasizes that liability under IRC Section 4960 can arise independently of IRC Sections 4958 and 4941, and the same payment or arrangement may trigger both IRC Section 4960 and either IRC Section 4958 or 4941 excise tax. The CRS analysis clarifies that IRC Section 501(c)(4) organizations are subject to similar prohibitions on private inurement and private benefit as IRC Section 501(c)(3) organizations, even though statutory language and IRS guidance for IRC Section 501(c)(4) organizations are less extensive. IRC Section 501(c)(4) organizations must operate primarily for the promotion of social welfare rather than for the benefit of private persons. CRS notes that both IRC Sections 4958 and 4960 apply to IRC Section 501(c)(4) organizations; however, IRC Section 4941 applies only to private foundations and, therefore, does not extend to IRC Section 501(c)(4) organizations. Finally, the CRS summarizes a series of legislative proposals that would expand or modify intermediate-sanctions rules. Proposals have included expanding the definition of "disqualified person," extending excise taxes to additional categories of organizations, and modifying or restricting defenses such as reliance on professional advice. While none of these proposals have been enacted, they reflect ongoing congressional attention to enforcement gaps and perceived abuses. The CRS report reinforces that intermediate sanctions imposed as a result of private inurement transactions are central enforcement tools in the federal oversight of tax-exempt organizations. For tax-exempt organizations, the CRS analysis underscores that compliance risks do not arise solely from intentional misconduct or egregious abuses. Routine governance decisions — particularly those involving executive compensation, related-party transactions, leases, loans, grants and use of organizational assets — can implicate these rules if they are not supported by careful documentation and independent decision-making. The report's examples of private inurement and private benefit reinforce the importance of maintaining strong governance protocols, including independent decision-making processes, documented valuation practices and vigilant conflict-of-interest oversight. The report also highlights the IRS's ability to apply graduated enforcement mechanisms, including excise taxes under IRC Sections 4958, 4941 and 4960, in lieu of or in addition to revocation of exempt status. The continued expansion of IRC Section 4960 means that compensation arrangements may trigger organizational-level excise taxes even when traditional private inurement or excess-benefit concerns do not exist. Exempt organizations should monitor their compliance with IRC Section 4960 in conjunction with compensation planning.
