A nonprofit’s Form 990 will tell you what an organization spends money on, who it pays, where its revenue comes from, and whether its finances are trending up or down. It will not tell you whether the organization is good at its work. Reading one well means extracting the handful of numbers that carry signal and ignoring the ratio that most people fixate on. The form is public, free, and filed annually by most tax exempt organizations above a small revenue threshold.
The sequence below takes about fifteen minutes.
Step 1: Find the filing
Start with the IRS Tax Exempt Organization Search. It confirms an organization’s current exempt status and hosts filed returns. Search by name or by Employer Identification Number, the nine digit number every registered organization has.
Two things are worth confirming before reading any numbers. First, that the organization appears in the database at all. Second, the classification it holds, because a 501(c)(3) public charity and a 501(c)(4) advocacy organization operate under different rules and file differently. The general rules about which organizations qualify and how deductibility works for a registered charity are worth understanding before reading a return, because the classification shapes what the form is even reporting.
Step 2: Read Part I before anything else
Part I is the summary page, and it carries most of the story. Four lines matter: total revenue, total expenses, net assets at the beginning of the year, and net assets at the end.
Subtract expenses from revenue. A positive number means the organization added to reserves that year. A negative number means it drew them down. Neither is automatically good or bad. A large surplus at an organization that describes itself as underfunded is one kind of signal. A deficit at an organization with years of reserves is a different and often unremarkable one.
Step 3: Read Part III in the organization’s own words
Part III is where the organization describes its three largest program activities and attaches a dollar figure to each. This is the most useful qualitative section on the form.
Read it for specificity. Descriptions that name activities, counts, and locations are doing different work than descriptions built from mission language. An organization that names the activity, reports how many people it served, and says where the work happened is making a checkable claim. One that reports advancing its mission of community wellbeing is not.
Step 4: Check Part VIII for where the money comes from
Part VIII breaks revenue into contributions and grants, program service revenue, investment income, and other sources. The mix tells you what kind of organization you are actually looking at.
An organization funded almost entirely by a handful of grants faces different pressures than one funded by many small contributions or by earned revenue. Concentration is the thing to notice. Heavy dependence on one or two sources is a structural risk regardless of how well the organization performs.
Step 5: Check Part IX for how the money gets spent
Part IX splits functional expenses into program services, management and general, and fundraising. This is the section that produces the widely quoted “overhead ratio.”
Use it, but do not over read it. The split depends on how an organization allocates shared costs, and reasonable filers allocate differently. A very high management share is worth a question. The difference between 78 percent and 84 percent on programs is mostly an accounting artifact, not a measure of effectiveness. Organizations that underinvest in their own infrastructure often score well on this ratio and perform badly in practice.
Step 6: Check Part VII for compensation
Part VII lists officers, directors, trustees, key employees, and the highest compensated employees, with their reported compensation. Read it against organization size rather than against an absolute number.
A six figure salary at an organization running a $40 million budget is ordinary. The same salary at an organization running a $400,000 budget is worth understanding. The useful comparison is against similar organizations of similar scale, not against a personal reference point.
Step 7: Skim the schedules
Schedule L reports transactions with interested persons, meaning business conducted with insiders or their family members. Schedule G covers professional fundraising arrangements and events, including how much a fundraising event grossed against what it cost to run. Schedule O contains narrative explanations the organization chose or was required to add.
None of these are automatically problems. Related party transactions happen for legitimate reasons and get disclosed precisely so they can be evaluated. What matters is whether the organization explains them.
A worked example
Take a hypothetical organization reporting $3,000,000 in total revenue and $2,850,000 in total expenses, with net assets rising from $1,100,000 to $1,250,000.
The surplus is $150,000, about 5 percent of revenue, and it reconciles with the $150,000 rise in net assets. Reserves stand at $1,250,000 against $2,850,000 in annual expenses, which is roughly five months of operating costs. That is a defensible reserve position rather than a warning sign.
Now suppose Part VIII shows $2,600,000 of the $3,000,000 coming from grants and contributions, and Schedule B indicates the contributions are concentrated among a small number of donors. The organization is financially stable this year and structurally exposed next year. Neither the surplus nor the reserve figure would have surfaced that on its own. The revenue mix did.
That is the whole method: read the numbers against each other rather than one at a time.
What a 990 cannot tell you
The form reports inputs and outputs in dollars. It does not measure whether the work changed anything. Two organizations with identical financial profiles can differ enormously in effectiveness, and nothing on the return will distinguish them.
The 990 is also a lagging document. Returns are filed months after the fiscal year closes, and the most recent available filing can describe a period well over a year old. It tells you what was true, not what is true now.
Used for what it is good at, though, it is the most reliable public window into a nonprofit’s finances that exists. The IRS publishes the instructions and the form itself for anyone who wants to see how each line is defined, and definitions are where most misreadings start.
