Nonprofit Explorer API

Nonprofit Explorer includes data for nonprofit tax returns processed by the IRS during the 2012-2015 calendar years. This generally consists of filings for the 2011-2014 fiscal years, but may include older records. The IRS data release includes only a subset of what can be found in the full Form 990s. In addition to the raw data, we've linked to PDFs of full Form 990 documents wherever possible.

Every organization that has been recognized as tax exempt by the IRS has to file Form 990 every year, unless they make less than $200,000 in revenue and have less than $500,000 in assets, in which case they have to file form 990-EZ. Organizations making less than $50,000 don’t have to file either form but do have to let the IRS they’re still in business via a Form 990N "e-Postcard."

Nonprofit Explorer has organizations claiming tax exemption in each of the 27 subsections of the 501(c) section of the tax code, and which have filed a Form 990, Form 990EZ or Form 990PF. Taxable trusts and private foundations that are required to file a form 990PF are also included. Small organizations filing a Form 990N "e-Postcard" are not included in this data. 

See the documentation for more details. No key is required.
