Fiscal sponsorship is a formal arrangement in which a 501(c)(3) public charity sponsors a project that may lack exempt status. This alternative to starting your own nonprofit allows you to seek grants and solicit tax-deductible donations under your sponsor's exempt status. When applying for fiscal sponsorship, you will often need to provide a proposal that explains:

• Your project: Why it’s needed, and its goals, objectives, method, evaluation, staffing, and budget. This is similar to a grant proposal. 
• How it advances the nonprofit’s mission.
• Other ways the nonprofit can benefit from being associated with your project.
