A nonprofit organization (NPO, also known as a non-business entity) is an organization that uses its surplus revenues to further achieve its purpose or mission, rather than distributing its surplus income to the organization’s directors (or equivalents) as profit or dividends. This is known as the distribution constraint. The decision to adopt a nonprofit legal structure is one that will often have taxation implications too, particularly where the nonprofit seeks income tax exemption, charitable status and so on. The nonprofit landscape is highly varied, although many people have come to associate nonprofit organisations with charitable organisations. Although charities do form an often high profile or visible aspect of the sector, there are many other types of nonprofits. Overall, they tend to be either member-serving or community-serving. Member-serving organisations include mutual societies, cooperatives, trade unions, credit unions, industry associations, sports clubs, retired serviceman’s clubs and peak bodies – organisations that benefit a particular group of people – the members of the organisation. Typically, community-serving organisations are focused on providing services to the community in general, either globally or locally: organisations delivering human services programs or projects, aid and development programs, medical research, education and health services, and so on. It could be argued many nonprofits sit across both camps, at least in terms of the impact they make. For example, the grassroots support group that provides a lifeline to those with a particular condition or disease could be deemed to be serving both its members (by directly supporting them) and the broader community (through the provision of a helping service for fellow citizens). Many NPOs use the model of a double bottom line in that furthering their cause is more important than making a profit though both are necessary to the organization’s success. Although nonprofit organizations are permitted to generate surplus revenues, they must be retained by the organization for its self-preservation, expansion, or plans. NPOs have controlling members or a board of directors. Many have paid staff including management, whereas others employ unpaid volunteers and even executives who work with or without compensation (occasionally nominal). Where there is a token fee, in general, it is used to meet legal requirements for establishing a contract between the executive and the organization. Designation as a nonprofit does not mean that the organization does not intend to make a profit, but rather that the organization has no owners and that the funds realized in the operation of the organization will not be used to benefit any owners. The extent to which an NPO can generate surplus revenues may be constrained or use of surplus revenues may be restricted.
