Supporting organization (charity) A supporting organization, in the United States, is a public charity that operates under the U.S. Internal Revenue Code in 26 USCA 509(a)(3). A supporting organization either makes grants to, or performs the operations of, a public charity similar to a private foundation. However, unlike donations to a private foundation, donations to a supporting organization garner the same higher deduction rate as donations to public charities. However, supporting organizations allow less control over the organization to the founders than private foundations. The Internal Revenue Code calls a public charity that relies on a supporting organization a "supported organization".
