(1) The structure of Chapter 42 permits the assessment of excise taxes under
different statutes for the same transaction. For instance, a self-dealing transaction (Section 4941) is frequently also a taxable expenditure (Section 4945), that may also affect the net investment income (Section 4940) and the qualifying distributions (Section 4942). See Treas. Reg. 53.4944-1(a)(2)(iv); Rev. Rul. 77161, 1977-1 C.B. 358; Kermit Fisher Foundation v. Commissioner, T.C. Memo. 1990-300.
(2) Section 4940 and Section 4942 are closely related. Expenses must be allocated
between Section 4940 (investment activities) and Section 4942 (charitable activities). See Treas. Reg. 53.4940-1(e)(1); Rev. Rul. 75-410, 1975-2 C.B. 446; Julia R. & Estelle L. Foundation, Inc. Commissioner, 598 F.2d 755 (2d Cir. 1979); Kermit Fisher Foundation v. Commissioner, above. Also, a deduction for expenses paid or incurred in any taxable year for the production of gross investment income earned as an incident to a charitable function may not be greater than the income earned from such charitable function which is includible in gross investment income for such year. See Treas. Reg. 53.4940-1(e)(2)(iv). However, deductions with respect to property used for an exempt purpose in excess of the income derived from the property may be treated as a qualifying distribution. See Treas. Reg. 53.4942(a)-2(d)(4).
(3) For taxable years beginning before December 21, 2019, Section 4940(e) and
Section 4942 were especially inseparable. Adjustments to the net value of noncharitable use assets impacts the investment tax calculations (under former Section 4940(e)) and the minimum investment return (Section 4942). Both taxes rely on determining qualifying distributions; Section 4942 applies them against undistributed income to compute the tax liability. The following examples illustrate several outcomes when changes are made to the first page of the Form 990-PF.
(4) Note that the examples below regarding Section 4940, which impose an excise
tax on the net investment income of most domestic tax-exempt private foundations, including private operating foundations, are for tax years beginning on or before December 20, 2019. For those years, the excise tax is 2% of net investment income, but is reduced to 1% in certain cases. For tax years beginning after December 20, 2019, the excise tax is 1.39% of net investment income, and there is no reduced 1% tax rate.
Example 1: The foundation engages in self-dealing expenditures. The foundation reported these amounts in Part I Column d as charitable disbursements. The IRS later disallows these amounts and the Part XII Line 1a amount is reduced. This in turn reduces the qualifying distributions. When the qualifying distributions for the year are less than: the sum of 1% of the net investment income and the product of 1) the 5-year average distribution ratio and 2) the net value of the noncharitable use assets, the foundation can’t use the Section 4940(e) 1% tax rate.

For Section 4942 purposes, undistributed income is offset by qualifying distributions. When the qualifying distributions are reduced or disallowed, the potential for tax on undistributed income arises. This flow of actions is demonstrated as follows:
| Form 990-PF line adjustment | Increase or decrease |
|---|---|
| Part I Line 26 Column (d) | Decrease |
| Part XII Line 1(a) | Decrease |
| Part XII Line 4 | Decrease |
| Part V Line 8 | Decrease |
| Part XIII Line 4 | Decrease |
Note: Part V of the Form 990-PF won’t be used for taxable years beginning after December 20, 2019, because the Taxpayer Certainty and Disaster Tax Relief Act passed on December 20, 2019, included legislation that reduced the 2% excise tax on the net investment income of a private foundation to 1.39%. This legislation also repealed the 1% special rate that applied if the private foundation met certain distribution requirements.
If Part V Line 8 is less than Part V Line 7, use the 2% tax rate for 4940. A decrease in qualifying distributions results in Section 4942 tax if Part XIII Line 6(e) is greater than zero.
Example 2: The foundation understates the net investment income (either understating investment revenues or over-allocating/overstating investment expenses or both). This directly increases the Section 4940 tax. Also, this decreases the distributable amount (Part XI). This decreases the amount of undistributed income to be offset by qualifying distributions in Part XIII. This flow of actions is demonstrated as follows:
| Form 990-PF line adjustment | Increase or decrease |
|---|---|
| Part I Line 27(b) | Increase |
| Part VI Line 5 | Increase |
| Part XI Line 2(a) | Increase |
| Part XI Line 7 | Decrease |
| Part XIII Line 1 | Decrease |
27
If the amount on Part XIII Line 1 is greater than the sum of Part XIII Lines 4(d) and 5, there will be an amount in Part XIII Line 6f. This amount is then reported on the subsequent year’s Form 990-PF Part XIII Line 2a.
Example 3: The foundation overstates the net investment income. The Section 4940 tax is reduced, and the distributable amount in turn is increased, increasing any possible Section 4942 tax.
Example 4: The foundation understates the non-charitable use assets. (This frequently occurs when the return preparer averages the beginning and end of year bank/brokerage balances in lieu of the month end balances.) The noncharitable use assets net value and the minimum investment return (Part X Lines 5 and 6) increases. In addition to affecting the subsequent year’s distribution ratio, it raises the threshold for meeting the Section 4940(e) reduced tax rate. For Section 4942 purposes, the distributable amount increases, thus increasing the chance for tax two years down the road.
Example 5: The foundation overstates the non-charitable use assets. The net value of non-charitable use assets decreases, as do the minimum investment return and distributable amount. This lowers the Section 4940(e) threshold, and the chance for a possible Section 4942 tax is reduced.
(5) Section 4941 and Section 4945 excise tax liability can commonly occur for the
same transaction. Many self-dealing transactions aren’t considered to be for Section 170(c)(2)(B) purposes, thus becoming taxable expenditures. On the other hand, a taxable expenditure isn’t necessarily a self-dealing transaction and viceversa. See Rev. Rul. 77-161, 1977-1 C.B. 358. Remember to apply the appropriate Code section and Regulations when analyzing each transaction.
Example 1: A foundation manager uses foundation funds to go on a vacation in the Bahamas. This transaction is both a self-dealing transaction and a taxable expenditure.
Example 2: The same foundation manager is a member of Church X congregation. The manager uses the funds to pay for a “recuperation retreat” for the church’s pastor and the pastor’s family in the Bahamas. The manager isn’t related to the pastor by blood or marriage, and the pastor and family aren’t otherwise disqualified persons with respect to the foundation. The foundation doesn’t have advance approval under Section 4945(g) to make grants to individuals. Due to lack of advance approval of the grant procedures under Section 4945(g), the transaction constitutes a taxable expenditure but not a selfdealing expenditure.
(6) An act subject to Section 4943 may also trigger other taxes in certain situations.
Example: A foundation purchases stock of a disqualified person’s wholly owned corporation directly from the disqualified person. The purchase of the stock constitutes a self-dealing transaction. If the foundation owns more than 2% of the total stock of the corporation, the purchase may trigger Section 4943. A donation
28
of the stock won’t constitute a self-dealing transaction but may trigger Section 4943.
(7) As with Section 4943, an act subject to Section 4944 may also trigger other taxes
in certain situations.
Example: The foundation bought stock of a disqualified person’s wholly owned corporation from the disqualified person. The corporation is a corporate sole entity used to shelter the disqualified person’s income and assets. The disqualified person isn’t a minister of a church and thus the entity constitutes a sham corporation. The purchase constitutes a jeopardizing investment and a selfdealing transaction. As with the previous example, if the foundation owns more than 2% of the total stock of the corporation, the transaction may also trigger Section 4943.
