Checked with real requests on 7 October 2026. Every figure on
this page is the source’s, printed with its tax period and
the time it was read.
The source — ProPublica, Nonprofit Explorer
What is read. Two questions of its API: /nonprofits/api/v2/search.json (a name, a state, a category, a subsection) and /nonprofits/api/v2/organizations/<EIN>.json (one organisation and its filings). No key is needed and none is used.
Where its figures come from. The IRS: the Annual Extract of Tax-Exempt Organization Financial Data (the lines of each Form 990, 990-EZ and 990-PF) and the Exempt Organizations Business Master File (names, places and classification codes). The filed returns it links are the IRS’s releases of the documents.
How fresh. As fresh as the IRS’s releases. On the day this page was checked, the newest figures were for tax periods ended in 2023, loaded into Nonprofit Explorer in August 2025, and its copy of the master file was dated 16 September 2026; returns for periods ended in 2024 were on file as documents only. Each record on this page prints its own dates.
Source: ProPublica, Nonprofit Explorer (its API), used under ProPublica’s Data Terms of Use. Its own citation: ProPublica Nonprofit Explorer API; IRS Exempt Organizations Business Master File Extract (EO BMF); IRS Annual Extract of Tax-Exempt Organization Financial Data. IRS data is a work of the United States government.
What those terms ask, and what this page does
- Cite ProPublica. Every record and every search answer here names it and links to it, and every organisation links to its own page on Nonprofit Explorer.
- Do not republish the data whole, or hand it on by itself. This page asks for one organisation or one page of search results at a time, when a reader asks, and shows it here. It offers no download and no feed, and its relay answers this page only, with the fields this page reads and no others.
- Do not change the data. Figures are printed digit for digit. The one sum made here is labelled as computed here.
- Do not charge for it or sell advertising against it. This page is free and carries no advertising.
- No guarantee. ProPublica does not guarantee the data’s accuracy or completeness, and neither can this page. Where this page and the filed return disagree, the return is right.
The codes, in words
What kind of organisation. The subsection code (501(c)(3), 501(c)(4) …), the foundation code and the filing requirement code are the IRS master file’s; their wording here follows the IRS’s own table of codes (its master file documentation, dated February 2024), shortened in places. A code is what the master file says, not a finding of this page: where an organisation’s returns are on file beside a code that says it files none, the page shows both.
The NTEE category. The code is the master file’s; its title is from the National Center for Charitable Statistics’ table of the National Taxonomy of Exempt Entities (26 major groups, 633 codes). Many organisations have no NTEE code, and the page says so.
Code tables: IRS, EO BMF; NCCS, Urban Institute, NTEE. Both read 7 October 2026.
What this page does not know
- Anything newer than the extract. Figures arrive one to two years after the year they cover.
- Postcard filers’ finances, and organisations that do not file (see Reading a year).
- Whether a return was amended. The source gives one set of figures for a tax period.
- Who the people are. No officer, director or donor is named here, and no address beyond city and state is shown or sent to your browser.
- Whether an organisation still exists or is still recognised as exempt today. The IRS’s own Tax Exempt Organization Search answers that; each record links to it, to be searched by EIN.
When the source does not answer
The page says so in words, with the reason the relay gives — slow, rate-limited, down, or an answer it could not read — and shows nothing made up in its place. If this browser has read the organisation before, that copy is shown, marked “Not live” with the time it was read. The relay itself keeps each answer for one day, and for up to thirty days serves its last copy, said so, when ProPublica cannot be reached.
What happens to what you type
A name, a filter or an EIN goes from your browser to a small relay on this site, which asks ProPublica; ProPublica sees this site’s server and the question, not you. The relay counts requests for five minutes under a keyed hash of your network address, so one visitor cannot use up everyone’s share, and writes no record of its own of who asked what. The web server that hosts this site may log requests, as servers do.
An open organisation lives in the address bar (#ein=…), which is what makes its link shareable; the site’s analytics may record an address as it stands. This browser keeps the last eight organisations it read (labs.charity.v1) to show when the source is down; “Forget these” under the search removes them. See also Legal.
