Fiscal sponsorship is a practical way to launch a charitable project without starting a nonprofit from scratch. Instead of applying for your own 501(c)(3), you can partner with an existing nonprofit—called a fiscal sponsor—who handles the legal and financial side, so you can focus on your mission.
Whether you’re an early-stage nonprofit founder, a for-profit company starting a charitable initiative, or a community organizer with a big idea, fiscal sponsorship can help you move faster and avoid red tape. But not all fiscal sponsorships work the same way. There are different models to choose from—each with its own pros, cons, and responsibilities.
Let’s take a closer look at the two most common types of fiscal sponsorship: Model A and Model C.
What Is a Fiscal Sponsor?
A fiscal sponsor is a nonprofit that supports another project or group by extending its tax-exempt status and managing certain administrative tasks. This setup allows the sponsored project to:
- Accept tax-deductible donations
- Apply for grants
- Stay compliant with IRS rules
- Skip the time and cost of forming a new nonprofit
This is especially helpful for projects that are new, short-term, or want to focus more on impact and less on paperwork.
Two Common Types of Fiscal Sponsorship
Most fiscal sponsorships follow one of two models: Model A or Model C. Here’s what you need to know about each.
Model A: Full Integration
In Model A, your project becomes part of the fiscal sponsor’s organization. Think of it like a department within the sponsor’s nonprofit.
- Legal structure: You don’t need your own business entity—the sponsor takes full legal responsibility.
- Support: The sponsor handles HR, payroll, insurance, accounting, and other admin work.
Ideal for: Projects with paid staff, large grants, or complex operations.
This is the most hands-on option. Your project is fully under the sponsor’s umbrella, which means you follow their policies and systems.
Model C: Grant-Based Relationship
Model C is more hands-off. Your project stays legally independent, but the sponsor agrees to accept donations and re-grant the funds to your project.
- Legal structure: You keep your own business entity.
- Support: The sponsor processes donations and ensures the money is used for charitable purposes.
Ideal for: Short-term campaigns, pilot programs, or groups that want to keep more control.
This model is often used by startups or companies with charitable arms that want a simple way to fund projects without forming a full nonprofit.
Which Fiscal Sponsorship Model Is Right for You?
Here are a few questions to help guide your decision:
- Do you already have a legal entity or business setup?|
- Do you need help with operations and staffing?
- Do you want to stay in control of your brand and daily decisions?
- Are you running a long-term program or a temporary initiative?
FAQs About Fiscal Sponsorship Models
Do I keep control of donations in Model C?
No. Donations go to the sponsor first. They then re-grant funds to your project, following agreed terms.
Who owns the project’s content or intellectual property?
Model A: The sponsor likely owns it unless you agree otherwise.
Model C: You usually keep ownership, but put it in writing.
Can I switch from Model C to my own nonprofit later?
Yes. Many projects start with Model C to test ideas, then transition to become their own 501(c)(3).
What are the fees?
Model A sponsors often charge 9–15% for full services. Model C sponsors usually charge less, around 4–10%.
Fiscal Sponsorship Isn’t One-Size-Fits-All
Choosing between Model A and Model C depends on your project’s goals, timeline, and how much support you need. Model A offers a full-service partnership; Model C gives you independence with financial oversight. Both can help you move faster, stay compliant, and focus on your mission.
