Fiscal sponsorship describes a number of varying contractual relationships that have through custom and practice developed between “sponsors” and “projects,” allowing charitable projects to receive deductible contributions. Having a charitable project fiscally sponsored by a sound and reputable fiscal sponsor may be an attractive alternative to starting a nonprofit, especially when an idea is being tested or incubated. There are several ways to properly structure such relationships, and it is important to get it right from the start. There are also a number of traps that can leave a project’s leaders vulnerable to losing typical rights associated with fiscal sponsorship, including the right to transfer the project to another 501(c)(3) entity, and/or losing funds raised for the project’s mission.
