Tax Filings by Year

Form 990 is an information return that most organizations claiming federal tax-exempt status must file yearly with the IRS. Nonprofit Explorer has IRS digitized Form 990 data for filings processed in 2012 and later. Duplicate download links may indicate a resubmission or amendment to this organization's original return. Organizations with gross receipts of less than $50,000 can file the form 990-N postcard filing, which doesn’t include financial details. All Form 990 data is from the IRS.

About This Data

What Is 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 financial information from tax returns processed by the IRS since the 2012 calendar years, as well as data extracted from digital filings. IRS summary data also includes limited 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 for 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?

Most organizations that have been recognized as tax exempt by the IRS have to file the 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 the 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," which does not contain financial details. Churches are not required to file Form 990.

Nonprofit Explorer has organizations that are claiming tax exemption in any of the 27 subsections of the 501(c) section of the tax code. Taxable trusts and private foundations that are required to file a form 990PF are also included.

Types of Nonprofits

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