This section enumerates 28 different types of nonprofit organizations that are exempt from some types of federal income taxes. Many states have laws that specify the types of nonprofit organizations that are exempt from state taxes, as well. Organizations described in Section 501(c)(3) are commonly referred to as charitable organizations. They are eligible to receive tax-deductible contributions but must not be operated for the benefit of private interests, nor may any part of a Section 501(c)(3) organization's net earnings benefit any private shareholder or individual.
