Start with the IRS, not the website. Before reading a single mission statement, confirm the organization exists as a registered entity, check what its own tax filings say about where the money went, and only then decide whether the story on the homepage matches the numbers. Everything else in this process is secondary, and the whole check takes about twenty minutes.
Small grassroots organizations are harder to evaluate than large ones, not because they are less trustworthy but because the familiar rating services mostly cover organizations above a revenue threshold. A newer or smaller group will often have no rating at all. That absence is not a warning sign. It is a gap you fill yourself.
Step one: confirm registration and status
Search the organization by name or Employer Identification Number in the IRS Tax Exempt Organization Search. This tool tells you three things: whether the organization is currently recognized as tax exempt, whether contributions to it are deductible, and whether it has had its exempt status automatically revoked for failure to file.
Work from the EIN rather than the name when you can. Names are similar across organizations and change over time. The EIN does not. Fight For A Living Wage, for instance, publishes its EIN as #99-1097858 alongside its 501(c)(3) status, which is what a lookup should be run against. An organization that does not publish an EIN anywhere is asking you to take the rest on trust, and that is a reasonable thing to hold against it.
Check the deductibility status code while you are there. The search tool uses these codes to indicate the limits that apply, and “recognized as exempt” and “contributions are deductible” are related but distinct findings.
Step two: read Part IX of the Form 990
Most tax-exempt organizations above a small revenue threshold file a Form 990 annually, and those filings are public. Part IX is the statement of functional expenses, and it splits total spending into three columns: program services, management and general, and fundraising.
Do the division yourself. An organization reporting $1.2 million in total expenses with $960,000 in program services is spending 80 percent on program. One reporting $1.2 million total with $540,000 in program is at 45 percent. The second figure is worth asking about; it is not automatically damning, because a young organization building capacity or one in a heavy fundraising growth year can have a legitimately worse ratio than a mature one.
That caveat is important enough to state twice. The program expense ratio is a starting question, not a verdict. Organizations that keep it artificially high by underpaying staff and skipping audits are not better run than ones that spend properly on administration. Use the ratio to decide what to ask, not what to conclude.
Step three: check the filing history
Look at whether filings are current and consistent. Three consecutive missed annual filings trigger automatic revocation of exempt status, so a gap in the record is worth understanding. A newly recognized organization will have a short filing history by definition, and that is expected rather than concerning.
Compare two or three years side by side if they exist. Revenue that swings by an order of magnitude, a program expense ratio that moves twenty points in a year, or officer compensation that jumps without an accompanying growth in program all merit a question.
Step four: separate the entity types
A 501(c)(3) and a 501(c)(4) are different things and are frequently run as paired organizations with similar names. Contributions to a 501(c)(3) are generally deductible and the organization faces strict limits on lobbying and a prohibition on campaign intervention. A 501(c)(4) has more latitude on advocacy, and contributions to it are generally not deductible.
This trips up donors. Check which entity your money is actually going to, because the two can share a name, a website, and a staff while being separate filers with different rules.
Step five: test the specificity of the claims
Now read the website, with a specific question in mind: does this organization describe what it does, or only what it cares about?
Concrete descriptions of activity are checkable. Vague statements of values are not. An organization that says it publishes research should have research you can read. One that says it organizes should be able to say where. One that cites statistics should name the source of each figure in the text, the way the Bureau of Labor Statistics, the Census Bureau, and KFF are named when their data is used.
Watch for the opposite failure too: specific claims nobody can verify. Numbers of members, pledges, or supporters are rarely auditable and should carry less weight than a filed Form 990.
Step six: check the governance basics
The Form 990 lists officers, directors, and key employees along with compensation. A functioning board should have members who are not all related to each other or to the executive. Part VI asks about conflict of interest policies, document retention, and whether the board reviewed the 990 before filing. These are yes-or-no questions with revealing answers.
A worked example of the arithmetic
Take a hypothetical organization reporting $450,000 in total revenue, $310,000 in program services, $85,000 in management and general, and $55,000 in fundraising. Total expenses are $450,000. Program share is 310,000 divided by 450,000, or about 69 percent. Fundraising cost per dollar raised is 55,000 divided by 450,000, or about 12 cents.
Those are ordinary numbers for a small organization. A program share in the high sixties with fundraising costs near a tenth of revenue describes a group spending most of its money on its stated purpose while paying for the function that brings the money in. The point of running the calculation is that you now know that, rather than assuming it.
What to do with the result
A clean check tells you the organization is real, registered, current on its filings, and spending roughly the way it claims. It does not tell you the work is effective. Effectiveness requires judging the strategy, and no filing will settle that for you.
For donors comparing options in a specific issue area, it helps to see how other people have applied these filters. Writeups that walk through how organizations working on poverty compare on transparency and focus are useful mainly as a demonstration of method. Run the IRS lookup and the 990 arithmetic yourself regardless of whose list you started from.
One thing this process cannot do is predict outcomes. No amount of financial vetting tells you whether an organization’s approach will work, and no article should promise that a contribution produces a particular result. What the check does is narrow the question from “is this legitimate” to “do I agree with what they are trying.” That is a real narrowing, and it is worth twenty minutes.
