What is a 501(c)(3)?

Wikipedia defines it this way:

"501(c)(3) organization is a organization fas, trust, unincorporated association, or other type of organization exempt from federal income tax under section 501(c)(3) of Title 26 of the United States Code. It is one of the 29 types of 501(c) nonprofit organizations in the US."

Additionally, there are two types of 501c3:

  • A public charity, identified by the Internal Revenue Service (IRS) as "not a private foundation", normally receives a substantial part of its income, directly or indirectly, from the general public or from the government. The public support must be fairly broad, not limited to a few individuals or families. Public charities are defined in the Internal Revenue Code under sections 509(a)(1) through 509(a)(4).
  • A private foundation, sometimes called a non-operating foundation, receives most of its income from investments and endowments. This income is used to make grants to other organizations, rather than being disbursed directly for charitable activities. Private foundations are defined in the Internal Revenue Code under section 509(a) as 501(c)(3) organizations, which do not qualify as public charities.
