A private non-operating foundation’s annual distribution requirement is roughly 5% of the average fair market value of its investment assets, paid out as qualifying charitable distributions. That figure, set under Internal Revenue Code Section 4942, is the floor Congress built to keep foundations from stockpiling wealth without producing charitable benefit. The exact dollar amount takes a specific calculation, and missing it triggers an excise tax that starts at 30% and can climb to 100% of the shortfall.
Which Foundations the Rule Applies To
The 5% payout applies to private non-operating foundations, which is the common grantmaking type: they primarily fund other organizations rather than run their own programs. Private operating foundations, the kind that spend most of their resources actively conducting charitable work such as running a museum or research lab, are exempt from this distribution mandate entirely. They still face most other private foundation rules, but not the excise tax on failure to distribute income.
The 5% is measured against the fair market value of assets not used directly for charitable purposes. In practice, that means the investment portfolio: stocks, bonds, real estate held for return, and similar holdings. Assets used to carry out the foundation’s charitable programs are excluded from the base.
How the Required Payout Is Calculated
The calculation begins with the average fair market value of the foundation’s noncharitable-use assets, determined from monthly valuations across the tax year. From that average, the foundation subtracts any acquisition indebtedness tied to those assets, such as a mortgage on an investment property. It also subtracts a reasonable cash reserve for operations, capped at 1.5% of the net asset value after debt.
Multiply the adjusted figure by 5% and you get what the IRS calls the minimum investment return.1Internal Revenue Service. Instructions for Form 990-PF From that, subtract certain taxes the foundation paid during the year, most importantly the 1.39% excise tax on net investment income, which has been the flat rate for all private foundations for tax years beginning after December 20, 2019.2Internal Revenue Service. Tax on Net Investment Income of Private Foundations: Reduction in Tax What’s left is the distributable amount, and that’s the number the foundation has to hit in qualifying distributions.
A simplified example makes the mechanics concrete. A foundation with $10 million in average investment assets and $150,000 in acquisition indebtedness starts at $9,850,000. Subtract a 1.5% cash reserve allowance of roughly $147,750 and the base falls to about $9,702,250. Five percent of that is around $485,112. If the foundation paid $13,900 in excise tax on investment income, the distributable amount drops to roughly $471,212. Actual numbers on any return depend on the foundation’s asset mix and the timing of its monthly valuations.
What Counts Toward the Requirement
Not every outlay satisfies the payout. To count as a qualifying distribution, an expenditure has to fall into a recognized category:
- Grants to public charities for religious, charitable, scientific, literary, educational, or other exempt purposes.
- Direct charitable activities the foundation runs itself, such as a scholarship program, a research initiative, or educational workshops.
- Reasonable administrative expenses tied to charitable operations, including salaries for staff who run grant programs and legal fees for grant agreements.
- Purchases of assets the foundation will use for its charitable programs, such as a building or program equipment, which count in the year of purchase.
The IRS draws a clear line between expenses that advance the mission and expenses that maintain the investment portfolio.3Internal Revenue Service. Qualifying Distributions: In General A grants manager’s salary counts. A portfolio manager’s fee does not. Foundations that try to fold investment overhead into their payout typically trip on this distinction.
Program-related investments can also count. These are investments made primarily to advance the foundation’s charitable purpose rather than to earn a return, such as low- or no-interest student loans, below-market loans to businesses in disadvantaged areas, or high-risk investment in nonprofit low-income housing.4Internal Revenue Service. Program-Related Investments The test is whether a profit-motivated investor would make the same investment on the same terms; if yes, it probably isn’t a PRI.
Grants to organizations that aren’t public charities, including most foreign organizations and other private foundations, require the granting foundation to exercise expenditure responsibility, which means a pre-grant inquiry, a written commitment from the grantee, detailed reporting on how funds were used, and reporting to the IRS.5Internal Revenue Service. Grants by Private Foundations: Expenditure Responsibility Skip those steps and the grant can be reclassified as a taxable expenditure rather than a qualifying distribution.
The Deadline to Distribute
The distribution requirement doesn’t have to be met inside the year that generates it. Under Section 4942, the initial excise tax applies to undistributed income that hasn’t been paid out before the first day of the second taxable year following the year in question.6Office of the Law Revision Counsel. 26 USC 4942 – Taxes on Failure to Distribute Income For a calendar-year foundation, the amount calculated for 2025 has to be distributed by December 31, 2026.
The distributable amount and the qualifying distributions get reported on Form 990-PF, due the 15th day of the fifth month after the tax year ends. Calendar-year foundations file by May 15, with an available extension to November 15.7Internal Revenue Service. Return Due Dates for Exempt Organizations: Annual Return The filing extension does not extend the distribution deadline. Those are separate clocks.
For long-term projects that need funds accumulated over multiple years, a foundation can apply for IRS approval to treat money as set aside now and paid out later, but that requires a separate advance filing on Form 8940.8Internal Revenue Service. Instructions for Form 8940
Carrying Excess Distributions Forward
A foundation that pays out more than required in a given year can carry the excess forward for up to five subsequent tax years.9Internal Revenue Service. Private Foundations: Carryover of Excess Qualifying Distributions That flexibility lets managers make larger grants when strong opportunities arise and draw on the carryover in leaner years.
The five-year window is firm. A foundation cannot refresh expiring carryovers by electing to treat current distributions as made out of corpus; the IRS has specifically shut that maneuver down.10Internal Revenue Service. Refreshing Expiring Distribution Carryovers of Private Foundations Unused excess simply expires.
Penalties for Underdistributing
The penalty structure is punitive by design. If a foundation fails to distribute its required amount, the IRS imposes a first-tier excise tax of 30% on the shortfall, reported on Form 4720.6Office of the Law Revision Counsel. 26 USC 4942 – Taxes on Failure to Distribute Income
The foundation then enters a correction period that runs from the first day of the tax year in which the failure occurred through 90 days after the IRS mails a notice of deficiency, with possible extension if the IRS finds more time reasonably necessary.11Internal Revenue Service. Correction Period: Failure to Distribute Income If any of the undistributed income remains at the close of that period, a second-tier tax of 100% of the remaining shortfall applies.6Office of the Law Revision Counsel. 26 USC 4942 – Taxes on Failure to Distribute Income
There is a narrow off-ramp. The IRS may abate the 30% first-tier tax if the foundation shows the failure was due to reasonable cause and not willful neglect, and the shortfall was corrected within the correction period.12Internal Revenue Service. Taxes on Private Foundation Failure to Distribute Income Reasonable cause is a high bar in practice. An honest accounting error or a delay liquidating illiquid assets might qualify. Forgetting, or simply choosing to defer grants, will not.
