Private Foundation

A private foundation is a type of 501(c)(3) tax-exempt organization that does not meet the public support tests required for public charity status. Most private foundations are funded by a single individual, family, or corporation — such as the Bill & Melinda Gates Foundation, the Ford Foundation, or the Walton Family Foundation. The IRS applies stricter regulations to private foundations than to public charities, including a mandatory 5% annual distribution requirement (the organization must distribute at least 5% of its investment assets each year in grants or program activities), strict self-dealing prohibitions that prevent transactions between the foundation and its substantial contributors, limits on business holdings, and a 1.39% excise tax on net investment income. Private foundations file Form 990-PF rather than the standard Form 990, and they must publicly disclose their grant recipients. There are two subtypes: operating foundations, which run their own programs, and non-operating (grantmaking) foundations, which primarily distribute funds to other organizations. While private foundations play a critical role in the philanthropic ecosystem by providing significant funding for research, education, and social programs, their governance structure concentrates decision-making authority, making transparency and accountability particularly important.
