A public benefit corporation is formed for the benefit of society. Typically, if you are going to apply to receive 501(c)(3) tax-exempt status from the Internal Revenue Service, you are going to choose to be a public benefit corporation. Again, 501(c)(3) status is determined by the IRS. To find out more information about tax exemptions, please visit the IRS Website at www.irs.gov. A mutual benefit corporation is one that benefits a specific group of people, most often their membership. Examples of mutual benefit corporations would be homeowners associations or social clubs. A religious nonprofit is organized primarily or exclusively for religious purposes.
