Tax Filings and Audits by Year

The IRS Form 990 is an annual information return that most organizations claiming federal tax-exempt status must file yearly. Read the IRS instructions for 990 forms.

If this organization has filed an amended return, it may not be reflected in the data below. Duplicated download links may be due to resubmissions or amendments to an organization's original return.

If you would like to download Form 990 document PDFs in bulk, the Internet Archive operates a mirror of the original bulk data.

Nonprofit organizations that spend $750,000 or more in Federal grant money in a fiscal year are required to submit an audit covering their finances and compliance. Some of these are program specific, while others, called “single audits,” look at the entire organization. Nonprofit Explorer has PDFs of these audits for some nonprofits for fiscal year 2016 and later. They’re provided by the Federal Audit Clearinghouse.

About This Data

Nonprofit Explorer includes summary data for nonprofit tax returns and full Form 990 documents, in both PDF and digital formats.

The summary data contains information processed by the IRS during the 2012-2018 calendar years; this generally consists of filings for the 2011-2017 fiscal years, but may include older records. This data release includes only a subset of what can be found in the full Form 990s.

In addition to the raw summary data, we link to PDFs and digital copies of full Form 990 documents wherever possible. This consists of separate releases by the IRS of Form 990 documents processed by the agency, which we update regularly.

We also link to copies of audits nonprofit organizations that spent $750,000 or more in Federal grant money in a single fiscal year since 2016. These audits are copied from the Federal Audit Clearinghouse.

Which Organizations Are Here?

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.

Types of Nonprofits

There are 27 nonprofit designations based on the numbered subsections of section 501(c) of the tax code. See the list »
