Form 990-PF: Every Grant Named, Every Dollar Counted

A Return Built for a Different Animal

Private foundations operate under rules that differ sharply from those governing public charities, and their annual return reflects that difference at every line. Where a public charity files the Form 990 to document a broad program, the 990-PF is built around two preoccupations: excise tax and grantmaking. Every private foundation — regardless of size, regardless of whether it made any grants at all — files the 990-PF. There is no 990-EZ equivalent and no 990-N postcard option. The full return is always required.

The return runs to fifteen parts, and it opens with an income statement and a balance sheet expressed in two columns simultaneously: one following accounting rules, one following tax rules. The difference between the two columns is not cosmetic. Tax-basis figures govern what the foundation actually owes and what it must distribute, so both sets of numbers carry legal weight. The Internal Revenue Service uses the tax column; auditors and analysts frequently use both.

The Machinery the Return Runs

Three obligations particular to private foundations flow directly through the 990-PF, and each has its own schedule.

The first is the excise tax on net investment income. Most private foundations owe a flat 1.39 percent tax on net investment income ↗ — interest, dividends, rents, and capital gains net of expenses — and Part VI of the return calculates it line by line. This is not a penalty; it is a standing levy, reduced from a previous two-tier structure in 2020.

The second is the distributable amount. Federal law requires private foundations to distribute at least five percent of the average fair-market value of their non-charitable-use assets each year, with a twelve-month grace period for satisfying the minimum. Part XI of the return derives that figure, and Part XII records what the foundation actually distributed. Falling short triggers an excise tax; the return is where the shortfall first becomes visible.

The third, and the one that makes the 990-PF genuinely useful to anyone outside the foundation, is Part XV: the grant list. Every grant and contribution the foundation approved during the year must be itemized — recipient name, recipient address, purpose, and amount. There is no materiality threshold and no aggregation permitted; a ten-thousand-dollar grant to a local food bank appears alongside a ten-million-dollar grant to a university hospital. That granularity is what no other public document in the sector provides. Candid (formed by the merger of GuideStar ↗ and the Foundation Center) has built much of its grantmaking database directly from Part XV data extracted across decades of 990-PF filings, making the return the backbone of foundation research in the United States.

The return also carries Part VIII, which lists the names, titles, and compensation of officers, directors, trustees, and highly compensated employees — and Part IX-B, which lists payments to independent contractors above fifty thousand dollars. For foundations with small staffs and large assets, the compensation lines attract scrutiny from journalists and policymakers alike.

What It Discloses and When

The 990-PF is due on the fifteenth day of the fifth month after the foundation's fiscal year ends — the same calendar as the 990. A six-month extension is available on Form 8868. Once filed, the return is a public document: the foundation must make its three most recent returns available for public inspection on request, and most are now accessible through the IRS's own Tax Exempt Organization Search database and through Candid's platforms within months of filing.

Automatic revocation applies here just as it does for public charities: three consecutive years without filing and the foundation loses its exempt status by operation of law, with no notice. For private foundations the consequences are compounding, because the foundation's donors will have been claiming charitable deductions the IRS may then challenge retroactively.

The 990-PF is an accountability instrument by design. Its drafters in the Tax Reform Act of 1969 intended foundation behavior to be observable, which is why the grant list exists in the form it does. Decades later, it remains the most detailed, reliable, publicly available record of where private philanthropic money actually goes.
