The private foundation distribution requirement obligates a private non-operating foundation to pay out at least 5% of the fair market value of its investment assets each year for charitable purposes. The rule comes from Internal Revenue Code Section 4942, and the penalty for missing it starts at a 30% excise tax on the shortfall and climbs to 100% if the foundation still hasn’t corrected the gap by the end of a defined correction period.
The 5% figure is a useful shorthand, but the actual dollar amount a foundation owes involves several adjustments, and the rules about what counts toward meeting the target are narrower than many boards assume.
Who the Rule Applies To
The payout requirement applies to private non-operating foundations, which are the common grantmaking type: they hold investment assets and distribute income to other charities. Private operating foundations, which spend most of their resources running their own charitable programs such as a museum or research lab, are exempt from the distribution mandate and from the excise tax on failure to distribute income. They still face most other private foundation rules.
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 investment, and similar holdings. A building the foundation uses to run its programs is not part of the base.
How the Distributable Amount Is Calculated
The calculation starts with the average fair market value of the foundation’s noncharitable-use assets, using 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 day-to-day operations, capped at 1.5% of the net asset value after the debt reduction.
Multiplying that adjusted figure by 5% produces what the IRS calls the minimum investment return.1Internal Revenue Service. Instructions for Form 990-PF Certain taxes the foundation paid during the year are then subtracted from that number. The largest is usually the 1.39% excise tax on net investment income, which has applied as a flat rate to 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 The remainder is the distributable amount: the minimum the foundation must pay out as qualifying distributions.
A simplified example. A foundation with $10 million in average investment assets and $150,000 in acquisition indebtedness starts with $9,850,000. A 1.5% cash reserve allowance of roughly $147,750 brings the base to about $9,702,250. Multiplied by 5%, that yields about $485,112. Subtracting $13,900 in excise tax on investment income leaves a distributable amount of roughly $471,212. The real numbers for any foundation will depend on its asset mix and monthly valuations.
What Counts as a Qualifying Distribution
Not every dollar the foundation spends counts toward the payout. Qualifying distributions include grants to public charities for religious, charitable, scientific, literary, educational, or other exempt purposes; money spent directly conducting the foundation’s own charitable programs; reasonable administrative expenses tied to charitable operations, such as salaries for staff who manage grant programs; and purchases of assets the foundation will use for its programs, counted in the year of purchase.3Internal Revenue Service. Qualifying Distributions: In General
The IRS draws a hard line between charitable operations and investment operations. A grant program manager’s salary counts. A portfolio manager’s fee does not. Legal work on a grant agreement counts; legal work on the investment portfolio does not. Foundations that try to sweep investment overhead into the qualifying distribution total tend to lose that argument.
Grants to organizations other than public charities, including grants to other private foundations and to foreign organizations that are not the equivalent of a U.S. public charity, still count as qualifying distributions, but only if the foundation exercises expenditure responsibility over the grant: a pre-grant inquiry, a written commitment from the grantee on use of funds, detailed reporting back, and disclosure to the IRS.4Internal 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.
Program-Related Investments and Set-Asides
Program-related investments, or PRIs, can also count toward the distribution requirement. A PRI is an investment whose primary purpose is furthering the foundation’s charitable mission rather than producing a financial return. Typical examples include low-interest or interest-free loans to students, high-risk investments in nonprofit low-income housing, and below-market loans to small businesses in economically disadvantaged areas where conventional financing is unavailable.5Internal Revenue Service. 6Office of the Law Revision Counsel. 26 USC 4942 – Taxes on Failure to Distribute Income This treatment requires advance IRS approval through Form 8940, filed electronically on Pay.gov before the end of the tax year in which the set-aside is made.7Internal Revenue Service. Instructions for Form 8940 The foundation must show the project is better accomplished by accumulating funds than by paying immediately, and the money must be spent on the specified project within five years, unless the IRS grants an extension for good cause.
When the Money Has to Be Out the Door
A foundation does not have to complete its qualifying distributions within the same year that generates the requirement. Under Section 4942, the first-tier excise tax applies to undistributed income only if it remains undistributed on the first day of the second taxable year after 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 distributable amount calculated for 2025 must be paid out by December 31, 2026.
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.8Internal Revenue Service. Private Foundations: Carryover of Excess Qualifying Distributions That gives the board room to make larger grants when a good opportunity presents itself and lean on the carryover in leaner years.
Carryovers cannot be refreshed. A foundation cannot extend an expiring carryover beyond the five-year window by electing to treat current distributions as made out of corpus; the IRS has specifically shut that down.9Internal Revenue Service. Refreshing Expiring Distribution Carryovers of Private Foundations Unused excess simply expires at the end of the fifth year.
Penalties for Distributing Too Little
The penalty structure is deliberately steep. A foundation that fails to distribute its required amount owes a first-tier excise tax of 30% on the undistributed portion, reported on Form 4720.6Office of the Law Revision Counsel. 26 USC 4942 – Taxes on Failure to Distribute Income
After the failure, the foundation enters a correction period that runs from the first day of the year in which the failure occurred through 90 days after the IRS mails a notice of deficiency, with a possible extension if the IRS decides more time is reasonably necessary to complete the distributions.10Internal Revenue Service. Correction Period: Failure to Distribute Income If any of the shortfall is still undistributed at the close of that period, a second-tier tax of 100% of what remains applies.6Office of the Law Revision Counsel. 26 USC 4942 – Taxes on Failure to Distribute Income
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.11Internal Revenue Service. Taxes on Private Foundation Failure to Distribute Income Reasonable cause is a high bar in practice. An accounting error or an unexpected delay in liquidating assets may qualify. Forgetting, or choosing to defer grants, will not.
