Fiscal Sponsorship: Accept Donations Without a New Nonprofit
Most people assume that accepting tax-deductible charitable donations requires forming a 501(c)(3) nonprofit. The IRS estimates that Form 1023 takes well over 100 hours to prepare, the review process runs 3 to 6 months, and according to GoHarness, most organizations spend between $500 and $2,500 or more on formation costs alone — before the ongoing compliance and governance obligations begin.
If your organization already has the infrastructure to run a charitable program independently, Model C fiscal sponsorship offers a faster path: accept tax-deductible donations and apply for foundation grants through a fiscal sponsor's 501(c)(3) status, without creating a new nonprofit from scratch.
What Is Model C Fiscal Sponsorship?
Model C fiscal sponsorship is a pre-approved grant relationship between a fiscal sponsor and an independent organization. As Propel Nonprofits describes it, sponsored projects under Model C are a separate legal entity from the sponsor, run their own programs and operations, and can solicit grants and other tax-deductible donations that are given to the sponsor for the charitable purpose of the project. Both the sponsor and the project retain their own EINs throughout the relationship. Unlike Model A fiscal sponsorship, where a project becomes an internal program of the sponsor, Model C keeps your organization intact. A donor gives to the sponsor, the sponsor reviews the gift, confirms it aligns with the approved charitable purpose, and re-grants the funds to your program. Your donors receive a tax-deductible receipt from the sponsor's 501(c)(3) — and the IRS requires the sponsor to exercise genuine discretion at each step, which is what makes those deductions valid.
Who Model C Fiscal Sponsorship Is Designed For
Model C is built for organizations with existing operational capacity that want to add tax-deductible fundraising to a clearly charitable program.
As the National Council of Nonprofits notes, fiscal sponsorship offers a way for a cause to attract donors even when it is not yet recognized as tax-exempt. What the IRS requires is that your program serve a genuine charitable purpose and that donated funds be used exclusively to advance it. Model C is not a structure for directing tax-deductible contributions toward for-profit operations or general commercial benefit.
Is Your Program a Good Fit for Model C Fiscal Sponsorship?
Use the table below to assess whether your program is a strong candidate.
| Your program is likely a good fit if... | Model C may not be the right path if... |
|---|---|
| You already operate with your own staff, finances, or legal structure | You want to redirect charitable donations to your organization's general operating budget |
| Your charitable program serves a defined charitable purpose independent of your commercial operations | Your charitable program and your business operations are intertwined |
| You can manage your own programmatic administration independently | You need HR, payroll, or employer-of-record support from a sponsor |
| You are seeking grant or donation funding specifically for a defined charitable purpose | Your funding needs are tied to revenue generation rather than charitable impact |
| You want to avoid forming a new 501(c)(3) for a program that may not warrant one | You need the sponsor to assume full legal and fiduciary control of your project |
If your program falls in the left column, Model C may be exactly what you need. If you find yourself in the right column, it is worth exploring whether Model A fiscal sponsorship or a different structure is a better fit for your situation.
What Model C Fiscal Sponsorship Unlocks for Your Program
Nonprofit Quarterly describes fiscal sponsorship as a tool that "produces private and public efficiencies through shared administration and fewer nonprofits requiring fiduciary and regulatory oversight." The table below shows what that means in practice.
| What It Unlocks | Without Fiscal Sponsorship | With Model C Fiscal Sponsorship |
|---|---|---|
| Tax-deductible donations | Not available without 501(c)(3) status | Donors give to the sponsor and receive a tax receipt |
| Foundation grant eligibility | Most foundations require a 501(c)(3) | Grants are awarded to the sponsor and re-granted to your program |
| Donor credibility | Donors may hesitate without tax-exempt backing | Giving is backed by an established 501(c)(3) |
| Your legal structure | N/A | You keep your own EIN and legal identity |
What to Have in Place Before Applying for Model C Fiscal Sponsorship
Because Model C is designed for organizations with existing operational capacity, fiscal sponsors typically look for programs that are already taking shape, not just an idea. Mission Edge generally partners with projects that have some initial funding or pledges in place, and the same holds for Model C candidates.
Strong Model C applicants typically bring:
A clearly defined charitable program with a specific, articulable public benefit
An existing organizational structure with the capacity to manage programmatic administration independently
A defined use of funds that is separate from general business or operating revenue
Some initial funding, pledges, or grant prospects that demonstrate the program's viability
A mission that aligns with the fiscal sponsor's charitable purpose and values
Model C Fiscal Sponsorship vs. Forming a New 501(c)(3)
The comparison comes down to one question: does your charitable program need its own permanent organizational structure, or does it need access to tax-exempt fundraising while you focus on the work?
For programs that are well-defined, compliant, and clearly charitable, Model C is often the more efficient path. For a fuller look at how the two options compare, this guide to fiscal sponsorship versus nonprofit formation covers the tradeoffs in detail.
The Shorter Path to Charitable Fundraising
If your organization is already running a charitable program, the path to accepting tax-deductible donations does not have to run through a new 501(c)(3). The National Council of Nonprofits reported a noticeable increase in fiscal sponsorship inquiries in 2024 — reflecting growing awareness that Model C offers a clean, compliant structure that keeps your organization intact while opening up the funding your charitable program deserves.
