An excess benefit transaction happens when a public charity, social welfare organization or 501(c)(29) health insurance issuer gives an insider more economic value than it receives back. Under Section 4958, the insider owes a 25% excise tax on the excess, rising by a further 200% if the deal is not corrected in time, and board members who knowingly approved it can owe 10%, capped at $20,000 per transaction.
The rules are often called intermediate sanctions because they let the IRS tax the individual who benefited instead of revoking the organization's exemption. This guide covers who counts as a disqualified person, how each excess benefit transaction tax is calculated, the rebuttable presumption that gives well-run boards a strong defense, how correction works and where everything is reported on Form 4720 and Form 990 Schedule L. Figures and forms are current as of October 2026.
The statute defines the term directly. An excess benefit transaction is "any transaction in which an economic benefit is provided by an applicable tax-exempt organization directly or indirectly to or for the use of any disqualified person if the value of the economic benefit provided exceeds the value of the consideration (including the performance of services) received for providing such benefit." The gap between what went out and what came back is the excess benefit, and that number is the base for every tax in this article.
Executive pay is the obvious case, though the definition reaches any transfer of value. Selling a building to a director below fair market value, leasing office space from an officer above market rent, paying an insider's personal expenses or forgiving a loan to a founder can each produce an excess benefit. Transactions with outsiders dealing at arm's length fall outside the rule entirely, because Section 4958 only applies when the recipient is a disqualified person.
Section 4958 sits alongside other insider rules that charities face. Organizations with employees earning more than $1 million should also review the Section 4960 excise tax on excess executive compensation, which the One Big Beautiful Bill Act widened from 2026. That tax falls on the organization, while Section 4958 falls on the person who received the benefit.
The statute calls covered entities applicable tax-exempt organizations. That means any organization described in section 501(c)(3), 501(c)(4) or 501(c)(29), plus any organization that held one of those statuses at any time during the five years ending on the transaction date. The statute then states that the term "shall not include a private foundation (as defined in section 509(a))." Private foundations face the separate self-dealing tax under section 4941 instead. Whether a 501(c)(3) counts as a public charity or a private foundation depends largely on the public support test.
Two arrangements face stricter versions of the rule. For donor advised funds and for supporting organizations described in section 509(a)(3), certain grants, loans and compensation paid to listed insiders count as excess benefit transactions in full, without any comparison to fair market value.
A disqualified person is anyone who, "at any time during the 5-year period ending on the date of such transaction," was "in a position to exercise substantial influence over the affairs of the organization." Voting board members, the president or CEO, the CFO and the treasurer almost always meet that test. A founder who left the board three years ago still counts, because the lookback runs five years.
The definition extends to related parties:
Being a disqualified person is a status, and it implies no wrongdoing. It means every payment and property deal with that person needs a documented basis for its value. Boards that already keep a conflict of interest register will find most of the same names on their Section 4958 list.
Section 4958 imposes three separate taxes, and the excess benefit is the base for all of them.
| Tax | Who pays | Rate | Limit | When it applies |
|---|---|---|---|---|
| First-tier tax, §4958(a)(1) | Disqualified person | 25% of the excess benefit | None | On every excess benefit transaction |
| Second-tier tax, §4958(b) | Disqualified person | 200% of the excess benefit | None | If the excess is not corrected within the taxable period |
| Manager tax, §4958(a)(2) | Organization managers who knowingly participated | 10% of the excess benefit | $20,000 per transaction | Only when the 25% tax applies and participation was willful and without reasonable cause |
The IRS summarizes the manager rule this way: the tax "may not exceed $20,000 with respect to any single transaction" and "is only imposed if the 25 percent tax is imposed on the disqualified person, the organization manager knowingly participated in the transaction, and the manager's participation was willful and not due to reasonable cause." Liability is joint and several, so when several directors approve the same deal, the $20,000 ceiling applies to the transaction as a whole.
The IRS intermediate sanctions page adds two practical points. A partial repayment reduces the second-tier tax, since "the 200 percent tax is imposed only on the unpaid portion of the correction amount." The 200% tax "may be abated if the excess benefit transaction subsequently is corrected during a 90-day correction period." The IRS overview of intermediate sanctions also states that it "may also propose revocation of tax-exempt status" in appropriate cases, whether or not Section 4958 taxes are imposed.
Assume a 501(c)(3) pays its executive director $260,000 for 2026. The board later obtains comparability data showing that similar organizations pay between $185,000 and $200,000 for the same role, and the IRS accepts $200,000 as reasonable.
| Step | Calculation | Amount |
|---|---|---|
| Compensation paid | Given | $260,000 |
| Reasonable compensation | Comparability data | $200,000 |
| Excess benefit | $260,000 minus $200,000 | $60,000 |
| First-tier tax on the executive director | 25% × $60,000 | $15,000 |
| Manager tax (board members who knowingly approved) | 10% × $60,000, under the $20,000 cap | $6,000 |
| Second-tier tax if not corrected | 200% × $60,000 | $120,000 |
| Total tax on the executive director if never corrected | $15,000 + $120,000 | $135,000 |
Correction requires repaying the excess plus interest. Using an assumed annual rate of 4% for illustration, compounded annually, and a repayment made exactly two years after the transaction, the correction amount is $60,000 × 1.04² = $64,896, which includes $4,896 of interest. Interest runs from the date of the transaction to the date of correction, and the actual rate must equal or exceed the applicable federal rate for the month of the transaction.
The manager cap matters on larger deals. If the excess benefit were $300,000, the first-tier tax would be $75,000, and 10% for managers would be $30,000, which the cap reduces to $20,000 for that transaction.
The statutory definition ends with a sentence that catches many organizations: "an economic benefit shall not be treated as consideration for the performance of services unless such organization clearly indicated its intent to so treat such benefit." When a perk is never reported as compensation, the full value becomes an excess benefit, even if total pay would have been reasonable had the perk been reported.
Common examples include personal use of an organization vehicle, a spouse's travel, club dues and housing paid on an executive's behalf. The regulations accept reporting the benefit "as compensation on an original Federal tax information return with respect to the payment (e.g., Form W-2, 'Wage and Tax Statement', or Form 1099, 'Miscellaneous Income') or with respect to the organization (e.g., Form 990, 'Return of Organization Exempt From Income Tax')." A year-end review of taxable and nontaxable fringe benefits should come before Forms W-2 are issued, and the 2026 Form W-2 changes make that check worth doing again this year.
Treasury Regulation §53.4958-6 gives boards a safe harbor called the rebuttable presumption of reasonableness. Under the regulation, payments "are presumed to be reasonable, and a transfer of property, or the right to use property, is presumed to be at fair market value" when three conditions are met:
Once all three are satisfied, the IRS "may rebut the presumption that arises under paragraph (a) of this section only if it develops sufficient contrary evidence to rebut the probative value of the comparability data relied upon by the authorized body."
Smaller charities get a simpler data rule. For organizations "with annual gross receipts (including contributions) of less than $1 million," the board is treated as having appropriate data "if it has data on compensation paid by three comparable organizations in the same or similar communities for similar services."
The documentation standard is specific. Minutes must record the terms approved and the approval date, the members present and voting, the comparability data relied on and how it was obtained, and how any conflicted member was handled. Records must be prepared "before the later of the next meeting of the authorized body or 60 days after the final action or actions of the authorized body are taken." A CFO or controller who prepares a compensation file before each review cycle makes all three steps easier, which is one reason boards bring in CFO support for nonprofits ahead of executive pay decisions.
Correction means "undoing the excess benefit to the extent possible, and taking any additional measures necessary to place the organization in a financial position not worse than that in which it would be if the disqualified person were dealing under the highest fiduciary standards."
The correction regulation sets the mechanics. The correction amount "equals the sum of the excess benefit (as defined in § 53.4958-1(b)) and interest on the excess benefit," and the interest rate "must be a rate that equals or exceeds the applicable Federal rate (AFR), compounded annually, for the month in which the transaction occurred." Payment generally has to be made "in cash or cash equivalents, excluding payment by a promissory note." In some property cases the disqualified person may return the property itself, subject to the regulation's conditions.
The taxable period starts on the date of the transaction and ends on the earlier of the date a notice of deficiency is mailed or the date the first-tier tax is assessed. Correcting within that window avoids the 200% tax.
Section 4958 taxes are paid by individuals, but the organization has reporting duties too.
Form 4720, Schedule I. The Form 4720 instructions state that "Schedule I must be completed by any Applicable organization or Disqualified person that engaged in an Excess benefit transaction, and by any fund manager who knowingly participated in the excess benefit transaction," and that "Each person must file separately." The organization "should not pay the tax liability of any disqualified person or organization manager." Disqualified persons and managers file "by the 15th day of the 5th month after the end of their tax year," which is May 15 for calendar-year individuals.
Form 990, Schedule L, Part I. An organization that answers yes on Form 990, Part IV, line 25a or 25b completes Schedule L, Part I. The Schedule L instructions require information for each excess benefit transaction "regardless of amount," including the disqualified person, the relationship to the organization, a description of the transaction and whether it "has been corrected." Managers who knowingly participated are identified in Part V. Schedule L, Part II also covers loans to and from interested persons, so a forgiven insider loan can appear in more than one place.
Schedule L entries are public, which is a strong incentive to catch issues before year end. Organizations that outsource nonprofit bookkeeping can ask for a monthly flag on any payment to a listed insider, and the same coding supports the compensation line in the statement of functional expenses. Charities with business income should also keep their Form 990-T and UBIT workpapers in the same annual compliance file.
What is an excess benefit transaction? It is a transaction in which a 501(c)(3) public charity, 501(c)(4) organization or 501(c)(29) issuer provides an economic benefit to a disqualified person that exceeds the value of what the organization receives in return. The difference is the excess benefit, and Section 4958 taxes it.
Who pays the tax on an excess benefit transaction? The disqualified person who received the benefit pays the 25% first-tier tax and any 200% second-tier tax. Organization managers who knowingly approved the deal can owe 10%, capped at $20,000 per transaction, and the organization itself should not pay these taxes on their behalf.
Do the Section 4958 rules apply to private foundations? No. The statute excludes private foundations from the definition of an applicable tax-exempt organization. Transactions between a private foundation and its insiders fall under the section 4941 self-dealing rules.
How long does a person stay a disqualified person? Five years. Anyone who held substantial influence over the organization at any time during the five years ending on the transaction date is a disqualified person for that transaction, along with their family members and 35-percent controlled entities.
Can the organization pay the tax for its executive? The Form 4720 instructions say the organization should not pay the tax liability of any disqualified person or organization manager. Each person liable for the tax files their own Form 4720.
