The donor's IRS Form 990 checklist: 5 lines that matter.
Every U.S. nonprofit with more than $50,000 in annual gross receipts files a Form 990 with the IRS — and every one of those filings is public. ProPublica's Nonprofit Explorer indexes roughly 1.8 million of them. The form has 12 parts and 16 schedules; almost nobody reads all of it. You don't have to. Here are the five lines that tell you whether a nonprofit is run well, in about 90 seconds.

Where to actually find a Form 990
The IRS provides direct downloads via Tax Exempt Organization Search, but the cleaner reading experience is ProPublica's Nonprofit Explorer — searchable by EIN or name, and it surfaces the three most recent filings side-by-side. Each Nonprofit/NGO detail page on GIVE→ALIGN links directly to the org's Nonprofit Explorer profile so you don't have to copy the EIN by hand.
Part I, Line 15 — Total executive compensation
Is the CEO paid in proportion to the mission?
Line 15 reports the total compensation paid to all officers, directors, trustees, and key employees. By itself the number is noisy — a large international Nonprofit/NGO will pay its CEO more than a soup kitchen, and that's fine. The signal is the ratio: divide Line 15 by Part I Line 18 (total functional expenses). For a healthy direct-service charity, executive comp typically sits between 1–3% of expenses. Above 5% on a multi-million-dollar budget without a clear specialist reason (e.g. a research institute employing PhDs) is worth a closer look at Schedule J for the breakdown.
Part IX, Lines 25(B) vs. 25(C) — Program services ratio
How much of every dollar reaches the actual work?
Part IX splits total expenses into three columns: program services (B), management & general (C), and fundraising (D). The number donors care about is column B as a share of the column A total — the program-services ratio. Charity Navigator awards full points above 70%; Candid considers anything above 65% acceptable for most cause areas. The 80–95% claims you sometimes see on giving pages almost always come from this exact calculation, so it's the fastest way to verify the headline.
Part VI, Sections A & B — Governance
Is there a real, independent board running this?
Part VI asks the questions our own active-board requirement is built on: how many independent voting members serve on the board (Line 1b), did the board review the Form 990 before it was filed (Line 11a), is there a written conflict-of-interest policy and an annual disclosure (Lines 12a-c), and a whistleblower policy (Line 13). Each yes is mundane on its own. A run of nos on a $1M+ budget is one of the loudest governance red flags the 990 will ever give you — and almost always pairs with the next item.
Schedule O — Narrative explanations
What did the nonprofit volunteer to say in its own words?
Schedule O is where every "explain" or "describe in Schedule O" from the rest of the form lands. It's also the most under-read page in the entire return. Skim it. A well-run nonprofit will use Schedule O to explain its mission concisely, describe how the board reviews the 990 before filing, and disclose any compensation methodology. A struggling one will use it to wave away a related-party transaction in a single sentence, or skip the disclosure entirely. The contrast between a thoughtful Schedule O and a perfunctory one is striking once you've read three or four of each.
Schedule B — Donor concentration (where required)
Is the funding base diversified, or one-grant-from-trouble?
Schedule B lists every contributor giving above the lower of $5,000 or 2% of total contributions. For public charities the donor names are redacted in the public copy, but the amounts and counts are not. If two or three contributions account for 70%+ of a nonprofit's revenue, the operation is genuinely fragile — a single grant cycle missing, and program work halts. This is neither a scandal nor a fraud signal; it is a stability signal. Recurring monthly donors are exactly the antidote, which is why the recurring-donate flow on most charity sites is the right place to give if you find a cause you genuinely want to back.
The cheat sheet: 5 red flags at a glance
None of these are individually disqualifying — every well-run nonprofit has had one of them in some year. The pattern that should prompt a closer look is two or more of these red flags appearing on the same 990, or the same flag persisting across three consecutive years.
Compensation > 5% of expenses without a specialist staffing reason (research institutes, hospitals).
Program-services ratio < 65% in mature operations (newly-founded orgs in their first 2 years are an exception).
Independent board members < 3 on any nonprofit with paid staff or > $250K revenue.
Blank or one-line Schedule O on an org that triggered "describe in Schedule O" references elsewhere on the form.
Top 2 donors > 70% of revenue two consecutive years — not disqualifying, but worth knowing before you commit.
What the Form 990 won't tell you
The 990 is an accountability document, not an impact report. It will tell you how much was spent on program services; it will not tell you whether those programs worked. For impact-side diligence you need to pair the 990 with three other sources: the nonprofit's most recent annual report (usually a 12–20 page PDF on their site), a third-party evaluator like GiveWell or ImpactMatters for the cause areas they cover, and — for direct-service charities — a recent independent program evaluation if one exists.
The 990 also says nothing about culture or governance dynamics inside the board room. A nonprofit can clear every line on this checklist and still be a difficult place to work. Reading recent Glassdoor reviews and the org's public press cycle covers that gap for most situations.
