Concept
A 501(c)(3) organization is a United States corporation, 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. 501(c)(3) tax-exemptions apply to entities that are organized and operated exclusively for religious, charitable, scientific, literary or educational purposes, for testing for public safety, to foster national or international amateur sports competition, or for the prevention of cruelty to children or animals. 501(c)(3) exemption applies also for any non-incorporated community chest, fund, cooperating association or foundation organized and operated exclusively for those purposes. There are also supporting organizations—often referred to in shorthand form as "Friends of" organizations. provides a deduction for federal income tax purposes, for some donors who make charitable contributions to most types of 501(c)(3) organizations, among others. Regulations specify which such deductions must be verifiable to be allowed (e.g., receipts for donations of $250 or more). Due to the tax deductions associated with donations, loss of 501(c)(3) status can be highly challenging if not fatal to a charity's continued operation, as many foundations and corporate matching funds do not grant funds to a charity without such status, and individual donors often do not donate to such a charity due to the unavailability of tax deduction for contributions. The two exempt classifications of 501(c)(3) organizations are as follows: 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)(0) through 509(a)(4).
