Nonprofit organization

Nonprofit organizations are organizations that meet two defining financial conditions: 1) They are subject to legal, ethical or other non-distribution constraints prohibiting transactions with owners or stockholders. 2) They are set up to legally accept contributed capital, in the form of gifts or donations.

A private nonprofit organization is any nonprofit organization not organized or controlled by or closely affiliated with a unit of government, while a public nonprofit organization has such origins, controls or affiliations. (See also nongovernmental organization).

Informal nonprofit organizations include a vast and uncounted array of self-governing groups, clubs, voluntary associations, coalitions, social networks. Formal nonprofit organizations are those that have one or more of the following: by-laws, operating rules, written policies and procedures, organization charts, goals, objectives, an established division of labor including governance, service delivery or advocacy programs, established offices, paid employees or other evidences of formal (intentional and durable) organization.

One large category of nonprofit organizations are formally organized nonprofit corporations which in the U.S. are typically chartered by an appropriate unit of state government (such as state-level Secretaries of State). A subset of these nonprofit corporations are also recognized by the Internal Revenue Service as exempt from federal income tax and eligible to accept tax-deductible contributions under Section 501-c-3 of the IRS Code. This makes them tax-exempt, tax-deductible nonprofit corporations, a phrase that is often shortened to "501-c-3's".
