TLDR
Fiscal sponsorship lets a project without 501(c)(3) status receive tax-deductible donations and grants by operating under a sponsor's tax-exempt umbrella. The two main models differ significantly in what the sponsor assumes and what control the project retains. Understanding when fiscal sponsorship makes sense — and when forming your own nonprofit is the better path — depends on your project's stage, ambition, and funding needs.
Fiscal sponsorship is one of those nonprofit concepts that’s widely used but frequently misunderstood. Development directors encounter it when reviewing grants to projects that don’t have their own 501(c)(3). Executive directors sometimes consider it as an alternative to the full IRS application process. New projects use it as a launchpad before deciding whether to form a permanent organization.
The mechanics matter because they determine what you’re actually agreeing to — as a sponsor or as a sponsored project — and the risks are different for each party.
What Fiscal Sponsorship Is
Fiscal sponsorship is an arrangement in which an established 501(c)(3) organization (the fiscal sponsor) uses its tax-exempt status to enable a project without tax-exempt status to receive tax-deductible donations and sometimes grants.
The sponsor agrees to take responsibility for the project’s activities as they relate to charitable purpose. In exchange, the sponsor typically charges a management fee — usually 5-15% of funds received.
This arrangement benefits the project by giving it access to tax-deductible fundraising and sometimes grant eligibility without waiting months for its own IRS determination. It benefits the sponsor by generating fee revenue and potentially expanding its programmatic footprint.
The key legal principle: money donated under a fiscal sponsorship arrangement is donated to the sponsor, not to the project. The sponsor has charitable ownership and control of the funds. This is what makes the donor’s gift tax-deductible. If the sponsor’s tax-exempt status is revoked, the gifts lose their tax-deductibility retroactively.
The Two Main Models
Greg Colvin’s framework, widely used in the field, describes six models of fiscal sponsorship. Two are by far the most common and the ones you’re likely to encounter.
Model A: Comprehensive Fiscal Sponsorship
In Model A, the fiscally sponsored project is fully integrated into the fiscal sponsor. The project operates as a program of the sponsor — not as a separate legal entity. The sponsor:
- Receives all funds for the project
- Employs project staff (or contracts them, with the sponsor as the contracting party)
- Owns any intellectual property created by the project
- Has full legal and financial responsibility for the project’s activities
- Can terminate the arrangement
The project director typically operates with significant day-to-day autonomy but is ultimately an agent of the sponsor. The project doesn’t have a separate bank account; funds flow through the sponsor’s accounts. The project director reports to the sponsor’s leadership.
What the project gets: Access to the sponsor’s 501(c)(3) status for fundraising, use of the sponsor’s administrative infrastructure (payroll, insurance, accounting), freedom to focus on program work rather than legal and administrative setup.
What the project gives up: Legal ownership of the project itself. The intellectual property, donor relationships, and programmatic assets belong to the sponsor. If the project wants to leave the sponsor and form its own nonprofit, it typically can — but negotiating the transfer of assets and donor relationships is complex.
Who uses it: New projects that are still proving their model, grassroots projects that want to remain small without administrative overhead, documentary filmmakers and artists who need to fundraise for a specific work, cause campaigns that aren’t intended to become permanent organizations.
Model C: Pre-Approved Grant Relationship
In Model C, the fiscally sponsored project maintains its own independent legal identity. The sponsor agrees to receive contributions on the project’s behalf and re-grant them to the project after verifying that the funds will be used for charitable purposes.
The flow: a donor writes a check to the sponsor earmarked for the project. The sponsor accepts the gift (making it tax-deductible), reviews the project’s use of prior funds to ensure charitable use, and then makes a grant to the project. The project has its own bank account and employs its own staff.
What the project gets: Tax-deductible fundraising for donors, sometimes access to grants that require a 501(c)(3) fiscal agent. The project retains its own identity, staff, intellectual property, and donor relationships.
What the project gives up: The management fee (same range, typically 5-15%), some reporting requirements to the sponsor, and the need for the sponsor to approve distributions.
The sponsor’s role: The sponsor must maintain a level of oversight to ensure the project is genuinely using funds for charitable purposes — this is what makes the donor’s gift tax-deductible. A sponsor that rubber-stamps distributions without any oversight creates legal risk for itself.
Who uses it: More established projects or organizations seeking a stepping stone to their own 501(c)(3), projects that want to maintain more independence than Model A allows, organizations awaiting their own IRS determination letter.
Common Use Cases for Fiscal Sponsorship
New Projects Testing Viability
A project that isn’t sure yet whether it will become a permanent nonprofit is a good candidate for fiscal sponsorship. Forming a 501(c)(3) costs money (state filing fees, IRS user fees, legal fees for setup), takes time (6-12 months for the full application), and creates ongoing compliance obligations (annual 990 filings, state charity registration). If the project might not continue after two years, the investment in its own legal structure may not be justified.
Fiscal sponsorship lets the project test its model, raise money, and apply for some grants before committing to permanent organization.
Artists and Filmmakers
Documentary filmmakers, visual artists, musicians, and performing arts projects frequently use fiscal sponsorship to receive tax-deductible donations for specific works. A documentary film is a finite project — it doesn’t make sense to form a permanent nonprofit organization to produce one film. A fiscal sponsor provides access to fundraising while the work is in production.
Many fiscal sponsors specialize in arts projects; Fractured Atlas is probably the most well-known, serving visual and performing artists across the country.
Cause Campaigns
A community campaign to build a park, organize around a specific policy issue, or respond to a local emergency may need to receive tax-deductible donations for a defined period without becoming a permanent organization. Fiscal sponsorship provides the fundraising infrastructure without the permanent legal overhead.
Organizations Awaiting IRS Determination
Under a Model C arrangement, an organization that has applied for its own 501(c)(3) can use a fiscal sponsor to receive donations while waiting for its determination letter (which can take 6-12 months for the full Form 1023). This is particularly useful if the organization has grant opportunities that require 501(c)(3) status.
What the Fiscal Sponsor Assumes
The sponsor’s liability exposure is the part of fiscal sponsorship that doesn’t get enough attention.
Under Model A, the sponsor is fully legally responsible for the project. If the project discriminates in hiring, violates HIPAA, creates intellectual property disputes, or misuses funds, the sponsor is on the hook. This is not a theoretical risk — there have been lawsuits against fiscal sponsors for the actions of their sponsored projects.
Model A sponsors should be conducting meaningful due diligence on projects they take on: reviewing the project director’s background, confirming the project’s activities are genuinely charitable, and maintaining oversight. “We just provide the bank account” is not a defensible fiscal sponsorship structure.
Under Model C, the sponsor’s exposure is more limited — the sponsor isn’t employing project staff or owning project assets — but the sponsor still must maintain sufficient oversight to confirm that grants distributed to the project are used for charitable purposes.
Management fees (typically 5-15%) compensate the sponsor for assuming these responsibilities and providing administrative services. A sponsor charging 5% is doing something different than a sponsor charging 15%; understand what the fee buys.
What the Project Gives Up
Beyond the management fee, sponsored projects give up:
Some control. The sponsor has authority over funds and, in Model A, authority over the project itself. Project directors who chafe at oversight need to be honest about whether fiscal sponsorship is the right structure for them.
Fundraising flexibility. Some major donors don’t like giving to fiscal sponsors because the donation technically goes to the sponsor, not the project. Some foundations won’t fund fiscally sponsored projects at all; others require that the sponsor (not the project) be the formal applicant. Know your funders’ policies before pursuing grants through a fiscal sponsor.
Direct donor ownership. In Model A, the donor relationships belong to the sponsor. If the project leaves, those relationships don’t automatically transfer.
Grant credit. Grants made through a fiscal sponsor are reported on the sponsor’s 990, not on any separate filing for the project. This can affect the project’s ability to demonstrate grant history if it later applies for its own funding.
When to Use Fiscal Sponsorship vs. Form Your Own Nonprofit
Fiscal sponsorship makes sense when:
- The project has a defined end point (a film, a campaign, a time-limited service)
- The project is in early stages and not yet sure it will become permanent
- The project lacks the administrative capacity to manage 501(c)(3) compliance
- The project’s founders don’t want to build a board, file 990s, or manage state charity registration
- The project’s funding needs are modest (large organizations rarely thrive as sponsored projects long-term)
Forming your own nonprofit makes sense when:
- The project is intended to be permanent
- The project’s budget is substantial enough that the management fee represents significant lost program funding (5% of $500,000 is $25,000 per year)
- The project’s funders or donors strongly prefer a direct relationship with an independent organization
- The project’s leadership wants full autonomy and ownership of donor relationships
- The project plans to pursue government grants that typically require direct applicant status
There is no universal right answer. Some organizations start under fiscal sponsorship and transition to independence; others remain sponsored projects for decades. The decision should be based on the project’s specific situation, not on a general preference.
How to Vet a Fiscal Sponsor
Not all fiscal sponsors are equal. Before entering a fiscal sponsorship arrangement:
Check their Form 990. The sponsor’s most recent 990 is publicly available. Look at their revenue, their overhead ratio, their management. A fiscal sponsor with serious financial problems is a risk — if they’re insolvent, your funds could be at risk.
Understand their due diligence process. What do they review before taking on a project? A sponsor with no vetting process is not exercising the oversight required for a legitimate fiscal sponsorship.
Review the fiscal sponsorship agreement carefully. Key provisions to understand: fee structure, how and when distributions are made, what happens if you want to leave, what happens to assets if the sponsor dissolves, intellectual property ownership, dispute resolution.
Ask for references. Talk to other projects they sponsor. Ask how responsive they are, whether distributions are timely, and whether the relationship is genuinely supportive.
Understand their expertise. If you’re running a substance use disorder program, a fiscal sponsor with no behavioral health experience is less equipped to exercise meaningful oversight of your program. Some sponsors specialize; others are generalists.
Check their state registration. Fiscal sponsors soliciting donations in multiple states need multi-state charity registration. A sponsor that isn’t properly registered in states where they’re fundraising on your behalf creates legal risk.
Fiscal sponsorship is a legitimate and useful structure for the right situations. The problems arise when projects or sponsors enter arrangements without fully understanding what they’re agreeing to — and when sponsors take on projects they lack the capacity to oversee responsibly.
