Excess Benefit
When an insider receives more than fair value, the tax penalty falls on them personally — not on the organisation.

The Mechanics of Intermediate Sanctions
An excess benefit transaction occurs when a tax-exempt organisation covered by Section 4958 of the Internal Revenue Code — primarily 501(c)(3) public charities and 501(c)(4) social welfare organisations — provides an economic benefit to a "disqualified person" that exceeds the fair market value of what that person gives in return. The term sounds abstract; the enforcement is not. The IRS imposes excise taxes directly on the individual who received too much, and on any organisation manager who knowingly approved the deal.
Congress introduced this mechanism in 1996, creating what practitioners call "intermediate sanctions" because they occupy the middle ground between doing nothing and the nuclear option of revoking an organisation's exempt status entirely. Before 1996 the IRS had one real lever: strip the exemption. In practice that harmed the people the organisation served more than anyone who had benefited improperly, so it was rarely pulled. Section 4958 ↗ gave regulators a proportionate tool.
A disqualified person is anyone who was in a position to exercise substantial influence over the organisation's affairs at any point during the five years before the transaction. That includes presidents, chief executives, chief financial officers, voting board members, and anyone who controls 35 percent or more of a related entity. Family members of those individuals, and entities they control, fall within the definition too.
The Penalty Structure
The excise tax on the disqualified person is 25 percent of the excess benefit — the amount received above fair market value. If the transaction is not corrected before the IRS issues a deficiency notice, a second-tier tax of 200 percent of the excess benefit applies. Correction means returning the excess amount to the organisation with interest; it is not optional and it is not satisfied by a payment to the IRS. Organisation managers who knowingly participated in the transaction face a separate 10 percent tax on the excess benefit, capped at twenty thousand dollars per transaction.
The burden of proving fair value rests initially on the organisation. The IRS regulations establish a safe harbour called the rebuttable presumption of reasonableness: if an independent body of the board approved the compensation, relied on appropriate comparability data, and documented its reasoning in writing at the time, a presumption arises that the compensation was reasonable. The IRS can rebut it, but the presumption shifts the burden and protects well-governed organisations. Treasury Regulation 53.4958-6 ↗ sets out exactly what the contemporaneous documentation must contain.
Compensation is the most common context, but the rule is not limited to salaries. Below-market loans, sweetheart leases, the purchase of assets at inflated prices, and royalty arrangements that favour the insider all qualify if fair market value is not exchanged.

What This Means for Governance
The rebuttable presumption safe harbour makes the mechanics of board process operationally significant. A compensation committee composed entirely of independent directors, meeting before the arrangement is finalised, recording in its minutes the comparability data it reviewed and how it weighted that data — that paper trail is the organisation's first line of defence. Minutes taken after the fact do not satisfy the contemporaneous requirement, and data pulled from general surveys without mapping it to comparable organisations and comparable positions is not adequate comparability data.
Part VI of the Form 990 asks whether the organisation has a written conflict-of-interest policy and whether officers and key employees are required to disclose interests that could give rise to excess benefit transactions. The answers are public. So is the compensation reported on Schedule J for individuals earning more than one hundred and fifty thousand dollars. Together those disclosures mean that potentially problematic arrangements are visible to regulators, journalists, and anyone else willing to look at the annual return.
The practical lesson is that excess benefit exposure is primarily a process failure. An organisation that sets compensation through a documented, independent, data-driven process, and records that process properly, is well positioned. One that lets the executive director negotiate their own compensation, or that cannot produce contemporaneous minutes, is not — regardless of whether the number itself turns out to be reasonable.
