501(c)(3)

The section of the Internal Revenue Code that designates an organization as charitable and tax-exempt. Organizations qualifying under this section include religious, educational, charitable, amateur athletic, scientific or literary groups, organizations testing for public safety or organizations involved in prevention of cruelty to children or animals. Most organizations seeking foundation or corporate contributions secure a Section 501(c)(3) classification from the Internal Revenue Service (IRS). Note: The tax code sets forth a list of sections-501(c)(4-26)-to identify other nonprofit organizations whose function is not solely charitable (e.g., professional or veterans organizations, chambers of commerce, fraternal societies, etc.).
