How to Read a Foundation's 990-PF (and What It Actually Tells You)

Every private foundation in the United States files an IRS Form 990-PF each year. It's public, it's free, and it's the single best source of truth about how a funder actually behaves — far more reliable than a mission statement or an "About" page. The catch: a 990-PF is a tax return, not a brochure. It's dense, the useful parts are scattered, and a single foundation's filing can run 50+ pages.

This guide walks through what's actually worth reading, where to find it, and how to turn one filing into a go/no-go decision on a prospect.

What a 990-PF Is

The 990-PF is the annual return private foundations must file with the IRS. Unlike public charities (which file the 990 or 990-EZ), private foundations file this specific form because they're held to different rules — including a requirement to pay out roughly 5% of assets each year and to disclose every grant they make.

That disclosure is the gift. A 990-PF tells you, in the foundation's own numbers:

• How much money it controls (assets)
• How much it gives away each year (total giving)
• Exactly who it funded, how much, and often why
• Who runs it (trustees and officers)
• Whether it even accepts applications

The Five Things Worth Reading

You don't need to read the whole return. Five sections answer almost every prospect-research question.

1. Assets — how big is this funder?

Near the top of the form, Part II (Balance Sheets) shows fair market value of assets at year end. This is the foundation's war chest. A funder with $4M in assets behaves very differently from one with $400M: smaller funders write smaller checks, fund locally, and often don't take outside applications at all.

2. Total giving — how much actually goes out the door?

Part I reports total contributions, gifts, and grants paid during the year. Pair this with assets to get a feel for pace. Because of the ~5% payout rule, a $100M foundation is generally moving ~$5M a year — that tells you the realistic ceiling on what they fund annually.

3. The grant list — the most valuable page in the document

This is the part most people skip and the part that matters most. Private foundations must itemize their grants, usually in Part XV (or an attached schedule), listing for each grant:

• Recipient name and location
• Amount
• Purpose
• The recipient's status

Read this like a guest list. The organizations a funder already supports tell you more about your odds than anything they say about themselves. If a funder has given ten grants to youth-education nonprofits in Ohio and you're a youth-education nonprofit in Ohio, you've found a real prospect. If every grant goes to universities and hospitals, a small community group probably won't break in.

4. Trustees and officers

Part VIII lists the people who run the foundation. For relationship-driven funders (most family foundations), this is your map of who decides. It also signals scale: a foundation with one trustee and no staff almost never takes cold applications.

5. The application question

Many 990-PFs include a line or attachment stating whether the foundation accepts unsolicited requests and, if so, how to apply. If it says "contributions are made only to pre-selected organizations" — believe it. That's the single most important filter in funder research, and it's why we surface an accepts-unsolicited flag on every foundation profile.

Turning One Filing Into a Decision

Once you can read those five sections, a prospect-research pass on a single funder takes a few minutes:

1. Assets + giving → is this funder big enough to matter, and what's the realistic check size?
2. Grant list → do they fund organizations like mine, in my region, for my kind of work?
3. Typical grant size → scan the amounts; is my ask in range?
4. Unsolicited? → can I even approach them, or is this invitation-only?
5. Trustees → if it's invitation-only, do I have a path to someone on the board?

If the answers line up, it's a prospect. If the grant list is all universities and the form says "no unsolicited requests," move on — fast. The whole point of research is to spend your energy on funders you can actually win.

Why You Don't Want to Do This One PDF at a Time

Reading a single 990-PF is straightforward. Reading enough of them to build a prospect list is not — there are tens of thousands of private foundations, the PDFs aren't searchable as a set, and you can't sort 40,000 filings by "funds my cause in my state."

That's the problem the Foundation Directory solves: every funder's 990-PF data — assets, total giving, itemized grants, typical grant size, and the unsolicited-applications flag — already parsed, structured, and filterable by cause and state. You read one funder's giving history when you're ready to approach them, and you let the directory handle the part that doesn't scale: finding the right funders in the first place.

Start with the funders most likely to fund work like yours, then open their profiles to read the giving history the way this guide describes.
