Sources include data collected by SalariesReview.com in its surveys of nonprofit organizations and data leased from: 1) the Urban Institute, 2) GuideStar, Philanthropic Institute, Inc., 3) ERI Economic Research Institute, Inc. 4) PAQ Services Inc., and 5) the IRS. Not all organizations are required to file annual reports. Exempt organizations with annual gross receipts of less than $25,000, churches, government units, political organizations, church affiliated schools below college level, and others (see www.irs.gov/pub/irs-pdf/i990-ez.pdf) may not be required to file Federally. Reporting rules also vary by state. SalariesReview.com derives its values from surveyed data, mainly leased, derived from optical character recognition reading of photographs of annual reports (Form 990s/EZs/PFs) provided by the US IRS under the Freedom of Information Act. ~3/4s of these reports contain no compensation data (and/or may have been missed in data extraction), and although combined with other sources, some entities may not be shown. Optical character recognition produces errors. Please read the Terms of Use found below. By your use of this site, you agree that SalariesReview.com and any leased sources listed in # 1 - 5 above are covered by the described Limitation of Liability and other terms found in Terms of Use below. No warranty is made that data shown are correct; check all data (links to the source Form 990s are provided).
