A nonprofit organization that is exempt from federal income tax under Section 501(c)(3) of the Internal Revenue Code and that receives its financial support from a broad segment of the general public. Religious, educational and medical institutions are deemed to be public charities. Other organizations exempt under Section 501(c)(3) must pass a public support test to be considered public charities, or must be formed to benefit an organization that is a public charity (see Supporting Organizations). Charitable organizations that are not public charities are private foundations and are subject to more stringent regulatory and reporting requirements (See Private Foundations).
