Private Foundations OneSheet PDF

Private foundations organized for charitable purposes are exempt from income taxes. They are differentiated from tax-exempt public charities by their narrow bases of control and financial support. Statistics on private foundations are compiled from Form 990-PF, an annual information return that includes data on excise tax liability, charitable distributions, administrative expenditures, as well as income statement and balance sheet information. Data are available for the following types of organizations:

  • Operating Foundations—Generally conduct their own charitable activities, e.g., museums
  • Nonoperating Foundations—Generally provide charitable support through grants and other financial means to charitable organizations; the majority of foundations are nonoperating
  • Section 4947(a)(1) Nonexempt Charitable Trusts—Charitable trusts treated as private foundations for tax purposes; may be operating or nonoperating

Microdata files

Microdata are individual organization-level data that can be used for research purposes.

The data are contained in XML, ASCII flat files, Microsoft Excel spreadsheets and Adobe Acrobat PDF. Documentation to assist with the files is included. (Free Adobe Acrobat reader, WinZip utility, and Microsoft Excel viewer software is available for download, if needed.)

SOI sample data files

This section contains microdata files for all Forms 990-PF sampled for the annual SOI studies of private foundations. The data for each of the annual studies are included in a comprehensive, "harmonized" dataset, with standardized variable names and codes based on the form revision of the latest available Tax Year.

The sample include returns filed by private foundations, exempt under Internal Revenue Code section 501(c)(3), and section 4947(a)(1) nonexempt charitable trusts. The stratified random samples are based on asset size and represent approximately 10 percent of Forms 990-PF filed; sampling rates of 100 percent are applied to large-asset classes. Microdata records contain most financial information from Forms 990-PF, as well as weights (to estimate the population), for each organization.
