Charitable and nonprofit organizations are located in Lakeland. These organizations aim to use surplus money for social welfare, rather than profit maximization. If surplus revenues are generated, they must be retained by the organization for its self-preservation, expansion, or plans. They are also exempt from income taxes. These organizations can work in many different fields, such as poverty eradication, popularization of science or religion, elimination of prejudice and discrimination, human rights defense, and so on. Exemption from taxes needs paperwork and certification of various kinds. Some well known foundations include the Elizabeth Glaser Pediatric AIDS Foundation, American Cancer Society, Inc., and the World Wildlife Fund. The guiding rules and regulations for charitable organizations are state-specific.
