How Do You Verify a Charity Is a Legitimate 501(c)(3)?
Get the organization's EIN (its IRS tax ID), look it up in the IRS Tax Exempt Organization Search at apps.irs.gov, and confirm it's listed as eligible to receive tax-deductible contributions. That's the core check, and it takes about two minutes. Deeper diligence — public Form 990 filings, watchdog profiles, and a short red-flag list — takes ten more.
This is the single most-asked question before people give, and it deserves a straight answer rather than reassurance. Below is the full verification stack, worked through with a live example: the Make More Marbles Foundation itself, EIN 92-2489150. Run the checks on us — that's what the EIN is published for.
Step 1: Get the EIN
Every U.S. nonprofit has an EIN — an Employer Identification Number issued by the IRS. It's the organization's fingerprint: names can be mimicked, but the EIN resolves to exactly one entity in IRS records. A legitimate charity publishes it somewhere obvious. This Foundation puts it in the footer of every page and in its donation FAQ.
Red flag at this step: an organization that can't or won't give you its EIN. That's not a maybe — that's a no.
Step 2: Check the IRS Tax Exempt Organization Search
Go to the IRS Tax Exempt Organization Search (TEOS) at apps.irs.gov/app/eos and search by EIN. You're confirming two things: the organization exists in IRS records, and it's eligible to receive tax-deductible charitable contributions. This is the authoritative source — not the charity's own website, not a social post, not a payment page.
Worked example: search 92-2489150 and you're looking at the Make More Marbles Foundation, a 501(c)(3) public charity. Two minutes, done, and now your donation's deductibility rests on IRS records instead of trust.
Step 3: Read the public filings
U.S. nonprofits above the smallest revenue thresholds file an annual Form 990 with the IRS, and those filings are public. Candid (formerly GuideStar) and ProPublica's Nonprofit Explorer both republish them free. You're skimming for three things: revenue roughly matching the organization's public claims, program spending that goes where the mission says, and officer names that match the humans on the website.
Newer organizations may not have filings visible yet — databases lag, and small orgs file simplified versions. That's not disqualifying by itself; it just shifts weight onto the other checks.
Step 4: Check what the organization publishes voluntarily
Compliance is the floor. What separates well-run charities is what they disclose without being required to:
- Named partners you can independently verify. This Foundation lists nine — Feeding America, Kiva.org, Baja Bound, Big Brothers Big Sisters of Arizona, and others — each an established organization with its own public record.
- Specific, checkable impact numbers. "Over $1,000,000 raised, 251 Kiva microloans, 36 countries" is falsifiable in a way "helping thousands" never is — and the Foundation's standard is to track and publish impact every year, not just at year-end.
- A transparent donation pipeline. Where does the money physically go? Here: through FreeDonateButton with zero platform fees, directly into the Foundation's Stripe account, with automatic receipts. The full fee-stack breakdown is in how much of your donation actually reaches the cause.
- A named, findable founder. Not a stock-photo board. This one is Brad Hart, whose Kiva lending record is itself public.
Step 5: Run the red-flag list
| Red flag | Why it matters |
|---|---|
| Pressure to give right now | Urgency is the scammer's substitute for verification time |
| No EIN available | Cannot be checked against IRS records at all |
| Cash, gift cards, or wire transfers requested | Untraceable rails; legitimate charities take cards and checks |
| Name mimics a famous charity | Sound-alike names are a classic post-disaster scam pattern |
| No verifiable address, leadership, or partners | Nothing for your two minutes of diligence to grab onto |
One more check: your own paperwork
Verification cuts both ways — the deduction is yours to protect. Donations to a qualified 501(c)(3) are generally deductible if you itemize; if you receive something of value in return, the deductible portion is reduced by its fair market value; and any single gift of $250 or more requires a written acknowledgment from the charity. A well-built flow does this for you — the Foundation issues receipts automatically via Stripe after every contribution. For your specific situation, ask a tax professional, not a website.
Once an organization passes all five steps, the remaining question isn't legitimacy — it's leverage: does this charity fund things that keep working? That's a different test, and it's the subject of the six mistakes well-meaning donors make. For how this particular foundation answers it, start with what the Make More Marbles Foundation is.
FAQ
What is an EIN and why does it matter?
An EIN (Employer Identification Number) is the IRS-issued tax ID every U.S. organization has — the charity equivalent of a fingerprint. It's what you use to look an organization up in IRS records. A legitimate charity publishes its EIN; the Make More Marbles Foundation's is 92-2489150, shown in its site footer.
Are donations to any 501(c)(3) automatically tax-deductible for me?
Donations to a qualified 501(c)(3) are generally deductible, but your personal deduction depends on your tax situation — typically you must itemize, and if you received something of value in return, the deductible amount is reduced by its fair market value. Keep receipts, and get written acknowledgment for gifts of $250 or more. Consult a tax professional for specifics.
What if a charity is new and has no Form 990 on file yet?
New organizations legitimately take time to appear in filing databases. In that case, weight the other checks more heavily: confirmed IRS determination or EIN lookup, a published EIN on their site, transparent leadership, named partners, and a direct donation flow. If none of those exist either, wait or give elsewhere.
What are the biggest red flags when donating?
Pressure to give right now, refusal or inability to provide an EIN, requests for cash, gift cards, or wire transfers, names that mimic famous charities with slight spelling changes, and no verifiable address or leadership. Legitimate organizations survive two minutes of checking; scams depend on you skipping it.
