What fiscal sponsorship is
Fiscal sponsorship is an arrangement in which an existing 501(c)(3) — the sponsor — extends its tax-exempt status to your project. Donations and grants are made to the sponsor and restricted to your work; the sponsor is legally responsible for those funds and for ensuring they're used for charitable purposes. In exchange, it typically charges an administrative fee, often a percentage of the funds you raise.
The practical payoff: your donors get a tax deduction and you can apply for grants that require 501(c)(3) status — all without your own IRS exemption. It's not a loophole; it's a recognized, well-established way to do charitable work under someone else's umbrella, governed by a written agreement.
Model A vs. Model C (the two you'll hear about)
There are several recognized models, but two come up most often:
- Model A — comprehensive (direct) sponsorship. Your project is legally part of the sponsor. Its employees are the sponsor's employees, its activities are the sponsor's activities, and the sponsor handles payroll, insurance, and compliance. You get the most support and the most oversight.
- Model C — pre-approved grant relationship. Your project is a separate legal entity (for example, an unincorporated association or LLC). The sponsor receives the funds and regrants them to your project, while making sure they're spent on charitable purposes. You keep more independence but take on more of your own administration.
The trade in one line
Model A buys you the most infrastructure and protection at the cost of independence. Model C buys you independence at the cost of doing more of your own back-office and compliance work. Pick based on how much you want the sponsor to carry.
When to use it instead of forming your own 501(c)(3)
Fiscal sponsorship often makes sense when:
- You want to start raising tax-deductible funds now, not after months of IRS review.
- The project is short-term or experimental and may not need to exist forever.
- You're testing whether the work and the funding are real before committing to running an organization.
- You'd rather focus on the mission than on payroll, filings, and a Form 990.
- A grant deadline is near and you don't yet have your own exemption.
Forming your own 501(c)(3) usually wins once the work is durable, big enough to justify the overhead, and you want full independence, your own board, and your own brand. Many organizations start sponsored and incorporate later — see choosing a nonprofit structure to weigh all the options.

How to find a fiscal sponsor
The right sponsor is an established nonprofit whose mission overlaps with yours and that runs sponsorship as a real program, not a favor. Start close to home, then widen the search:
- Mission-aligned nonprofits in your field — many larger organizations sponsor projects in their area of work.
- Community foundations and arts/social-impact umbrellas that offer fiscal sponsorship as a stated service.
- National sponsor networks and directories that list organizations sponsoring projects across many causes.
- Your own network — peers, funders, and advisors often know a reputable local sponsor.
Before signing, vet the sponsor like a partner: confirm their 501(c)(3) status, read the written agreement, understand the fee and which model (A or C) they use, and ask how quickly funds are passed through and reported. A good sponsor is transparent about all of it.
Build recurring income either way
Whether you're fiscally sponsored or running your own 501(c)(3), durable funding is what keeps a project alive. Good Circles gives you recurring, unrestricted income with almost no staff time: supporters pick your cause once, then a share of their everyday local spending funds you automatically — about $72 per active supporter per year (≈ $36,000/year from 500 supporters), free to join.

FAQ
What is fiscal sponsorship?
Fiscal sponsorship is an arrangement where an existing 501(c)(3) extends its tax-exempt status to your project. Donations and grants flow through the sponsor, which is legally responsible for the funds and usually charges an administrative fee (commonly a percentage of funds raised). It lets you receive tax-deductible gifts and grants without having your own IRS exemption yet.
What's the difference between Model A and Model C fiscal sponsorship?
In Model A (comprehensive or direct), your project is legally part of the sponsor — its staff are the sponsor's employees and its activities are the sponsor's activities. In Model C (pre-approved grant relationship), your project is a separate entity and the sponsor regrants funds to it while ensuring they're used for charitable purposes. Model A means more support and oversight; Model C means more independence.
Is fiscal sponsorship better than starting my own 501(c)(3)?
It depends on your stage. Fiscal sponsorship is often better for new, short-term, or testing-the-waters projects because it lets you raise tax-deductible funds immediately without months of IRS paperwork. Forming your own 501(c)(3) usually makes sense once the work is durable, large enough to justify the overhead, and you want full independence and your own brand.
