Most charity watchdogs stop at a single number. They pull the ratio of program spending to total revenue, rank the organization, and move on. That number is self-reported, allocated by the same people who benefit from it, and tells you almost nothing about whether an organization is well run. The filing itself is more interesting. Read end to end, it is one of the few places where a nonprofit has to describe its money, its board, its insiders and its habits in the same document, in a fixed order, on a form that an officer signs.

What follows is a reading order, not a verdict machine. Everything here produces questions. Some have innocent answers in Schedule O or in a footnote. Ask them anyway.

Start at the summary, then walk backwards

Part I of the Form 990 compresses the whole year into a handful of lines: revenue, expenses, the split between program and overhead, net assets at the start and the end. It is also the most polished page in the packet, because it is the one people look at.

Read it, then immediately test it. Turn to Part III, where the organization describes its program achievements in prose and, crucially, lists its three largest programs with the expense attached to each. If the summary says 82 percent of spending went to programs but Part III describes one modest program and a vague second, you have a question about allocation, not a scandal — yet. The gap between the story and the numbers is where real reporting begins.

Then compare the current filing with the two before it. Put the revenue, total expenses and net assets side by side. A charity that has doubled in size in two years, or halved, is telling you something is changing faster than its governance probably is.

Part VI is the governance questionnaire — read the "no" column

This section asks a string of yes-or-no questions about how the board works: whether it has independent voting members, whether officers and directors must disclose conflicts annually, whether there is a whistleblower policy, a document retention policy, a process for setting executive pay, and whether the board itself reviews the finished filing before it goes out.

No single "no" is damning. Small organizations legitimately lack formal policies. What matters is the pattern. A board that does not review its own tax return, has no conflict-of-interest process, and simultaneously reports large payments to insiders is a chain of small failures that reinforce each other.

• A board with a majority of family members or paid staff is a board that cannot say no.
• Someone listed as an officer with "0.0" average hours per week, while drawing a salary, is worth a call.
• Family or business relationships disclosed in Part VII, column C, are not misconduct — but they change how you read every related-party line later.
• An unanswered or blank question is not the same as "no," and both are worth noting.

Follow the money in

Part VIII breaks revenue into its sources, and the shape of that breakdown says more than the total. A group funded mostly by many small contributions is accountable to a crowd. A group funded by one foundation grant or one government contract is accountable to that funder, and vulnerable the moment it disappears.

Watch for three specific things:

1. Concentration. If one line dominates, find out who is behind it in the notes, Schedule O, or the attached financial statements.
2. The "other" trap. Lines labeled other, with a large number and a thin description, hide activity. There is usually a breakout or a narrative somewhere; go find it.
3. Negative and netted figures. Fundraising events are reported gross, with costs beside them. An event that consistently raises less than it costs, year after year, is often a social club wearing a lanyard.

Follow the money out: the expense matrix

Part IX is a grid: rows of expense types, columns for program, management and fundraising. The grid rewards a slow, suspicious read.

Large salaries split across three columns are normal. What is not normal is a salary split that shifts dramatically year to year with no change in headcount, a sudden concentration of "professional fees" with no named purpose, or an "other expenses" line that swells and gets a one-sentence explanation. Travel and conference lines that dwarf comparable organizations deserve a question about who attended and why.

Be careful with the program ratio here. It is an allocation, and allocations are judgments. A charity can move a finance director's salary into programs by arguing the person spends time on grants. That is not fraud. It does mean the ratio is a claim, not a measurement — and it means you should compare the ratio against Part III's descriptions, not against a benchmark you found online.

Related-party transactions: Schedule L and the numbers around it

Schedule L is where insiders show up in the money. It asks about loans to and from officers, business deals between the organization and its directors, grants to people or entities connected to insiders, and any excess benefit transaction — the technical term for an insider getting more than fair value.

A filing can show no Schedule L and still have a related-party problem, because the thresholds and definitions do real work. Read the parts together:

• Part VII lists officers, directors, trustees and key employees. Note who is paid and who is not.
• Schedule R maps the organization's relationships with for-profit and nonprofit affiliates. Payments between family members of organizations are the most common place where money quietly moves.
• Schedule J details compensation for the top people: severance, deferred pay, housing allowances, club dues, first-class travel. Compare the total against the size of the organization's budget.

Two directors owning the same property company, a board chair whose consulting firm appears in professional fees, a founder's relative on payroll with a title but no listed duties — none of these is proof of wrongdoing. All are legitimate questions with paper answers somewhere.

Read for what is missing

Investigators spend too little time on absences. A generous revenue line with a blank Part III means nobody is describing what the money bought. A petition for a fiscal-year change, a re-filed return, or a string of late filings suggests administrative strain that often precedes financial strain. If the organization's own audited statements are attached, look at the auditor's language: a "going concern" paragraph is a warning written in plain English by an accountant who is not paid to be dramatic.

Schedule O deserves a full read. It is where organizations explain the strange lines — and where vague, recycled sentences are most visible. Compare this year's Schedule O with last year's. Identical boilerplate, copied word for word, tells you how much attention the filing received.

A one-hour routine

For a first pass on any filing, work in this order: summary page, then three-year comparison of revenue and net assets; Part VI answers; Part VII names, hours and pay; Part VIII concentration; Part IX outliers; Schedule L, J, R and O; then the prior two filings to see what changed. Write down contradictions as you go, because that list is your reporting plan.

Keep two habits. First, treat every flag as a question with a possible boring answer, and ask it plainly — most organizations will explain, and the explanation is itself information. Second, when a finding starts pointing toward tax exposure, self-dealing or employment issues, get a professional opinion before publishing or acting; the difference between an eccentric filing and a legal problem is often a detail only a practitioner will catch. The filing tells you where to look. It does not tell you what you found.
