Find out before you spend forty hours on the application.
Organizations write federal grant applications they were never able to submit. The exemption was automatically revoked. The SAM.gov registration expired. The Unique Entity ID was never issued. Every one of those is a hard stop, every one is public, and no free tool checks them together.

What a report looks like
The same report is available here as a page you can link to, as JSON, and from the command line. All three come from the same code and the same data, so they cannot disagree.
What it checks
Exempt status
Whether the IRS records an unconditional 501(c)(3) exemption. Most federal programs require it.
Automatic revocation
Three missed years revokes the exemption by operation of law. Being on the list is not the same as being revoked today.
Distance to revocation
How many years since the last filing. Nobody publishes this number, and it is the leading indicator.
SAM.gov registration
The single most common avoidable disqualification. Registrations lapse annually and renewal is not automatic.
Publication 78
Eligibility to receive tax-deductible contributions — and why a group subordinate is absent from it on purpose.
Single audit threshold
$750,000 or $1,000,000 depending on when your fiscal year began. Most organizations do not know which applies.
More than one at a time
Everything above is free and needs no account, and that will not change — a report is a public fact about a public record. What an email address unlocks is the part that has to remember something:
Check a whole list
Paste up to 200 EINs and get one table. A funder screening applicants, a fiscal sponsor reviewing projects, a consultant with a client list.
Get told when it changes
Save a roster and we re-check it against every monthly IRS release. You get an email only when a verdict actually moves — not a digest, not a newsletter.
Export it
CSV of the whole roster with findings and dates, for a spreadsheet or a board packet.
Sign in with an email address — no password, and the link is the whole of it. We send your sign-in link and the alerts you asked for, nothing else, and deleting your account takes one button and happens immediately. Or skip us entirely: the command-line tool does all of it on your own machine.
Why you can check our work
Every line of every report names the dataset it came from and the date that dataset was published. Nothing is inferred silently: where the tool has to guess — matching an organization to its SAM.gov registration, which cannot be looked up by EIN — it prints the confidence and tells you how to correct it.
It is Apache 2.0 and the whole thing is on GitHub. The command-line tool runs with no account, no API key, and no connection to us. You do not have to trust this site; you can run it yourself.
Run it locally
What this is not. It is not an eligibility determination. It reports observable facts and what they usually mean. There is no score, no grade, and no probability, because the honest answer to "will we win this" is not in any of these datasets.
