Self-Dealing: the Rule That Catches Founders

Here the two vehicles diverge sharply, and the distinction is the single most misunderstood point in private philanthropy. Public charities and 501(c)(4)s are policed by IRC §4958, “Taxes on excess benefit transactions” intermediate sanctions, which prohibit an excess benefit — an insider receiving more than the value of what they provide. Reasonable compensation is fine; the statute polices the excess.

Private foundations are governed by IRC §4941, “Taxes on self-dealing”, and it is categorically stricter. Self-dealing is prohibited outright, whether or not the terms are fair. A foundation may not sell property to a disqualified person, buy property from one, lend to or borrow from one, or let one use its assets — even at arm’s length, even at a price demonstrably favorable to the foundation. Selling your foundation a building at a bargain price is still self-dealing. Letting the foundation’s art hang in your house is self-dealing. The tax is 10% of the amount involved on the self-dealer, 5% on a foundation manager who knowingly participated, and 200% if the transaction is not unwound within the correction period. The only meaningful exception is reasonable compensation for personal services actually necessary to the foundation’s exempt purpose — which is why paying a family member a defensible salary works while almost every other transaction does not.

A disqualified person is broadly drawn under IRC §4946(a) for foundations, and under IRC §4958 means anyone able to exercise substantial influence over the organization at any point in the five years before the transaction: voting board members, presidents and chief executives, treasurers and chief financial officers, substantial contributors, and — critically — their family members and the entities they control.

Four further prohibitions apply only to private foundations and routinely surprise founders who fund with closely held stock: IRC §4943 excess business holdings (the foundation and its insiders generally may not hold more than 20% of a business), IRC §4944 jeopardizing investments, IRC §4945 taxable expenditures (lobbying, grants to individuals without an approved procedure, grants to non-charities without expenditure responsibility), and the payout rule above.

If you are creating a charity to benefit yourself, stop. The structure will not survive contact with an examiner, the penalties compound, and revocation of exempt status is on the table. Build policies before you need them: a written conflict-of-interest policy, contemporaneous compensation-comparability data before setting any insider’s pay, and board minutes that record the disinterested members approving it. That paper trail is the difference between a defensible compensation decision and a self-dealing deficiency.
