Fiscal sponsorship is an arrangement that lets a project or organization without its own 501(c)(3) status accept tax-deductible donations and pursue grant funding by partnering with an existing tax-exempt organization. The sponsor receives contributions on the project’s behalf, ensures the money serves a charitable purpose, and handles the compliance work that comes with exempt status. In exchange, the sponsor charges a fee and takes on varying degrees of legal responsibility for the project’s activities, depending on which model the two parties choose.
People turn to fiscal sponsorship because getting your own 501(c)(3) recognition through IRS Form 1023 takes months, sometimes longer. The application demands detailed governance documents, financial projections, and narrative descriptions of planned activities. A new project that wants to start accepting donations and applying for grants right away can’t afford to wait. Sponsorship bridges the gap while the project builds a track record or decides whether independent incorporation makes sense at all.
The whole arrangement rests on Revenue Ruling 68-489, which permits a tax-exempt organization to distribute funds to non-exempt entities only if the sponsor keeps “control and discretion as to the use of the funds” and maintains records confirming the money went to exempt purposes.1Internal Revenue Service. Revenue Ruling 68-489 That control requirement runs through every version of fiscal sponsorship. A sponsor that behaves as a passive conduit can lose donors their deduction and put its own exempt status at risk.
The Six Models
The standard classification comes from Gregory Colvin’s book Fiscal Sponsorship: 6 Ways to Do It Right, which labels the models A through F. They differ in how deeply the sponsor absorbs the project and who bears legal and financial responsibility.
Model A: Comprehensive Sponsorship
The project becomes an internal program of the sponsor with no separate legal identity. The sponsor employs all staff, owns all assets including intellectual property, and carries full legal liability for the project’s activities. Workers sit on the sponsor’s payroll and are covered by the sponsor’s workers’ compensation, benefits, and employment policies. This is the deepest form of integration. It suits projects that need an employer-of-record and can accept that what they create during the sponsorship belongs to the sponsor.
The intellectual property point catches many founders by surprise. Under Model A, work produced during the sponsorship generally belongs to the sponsor, not to the project team. If the project ever spins off into its own organization, the sponsorship agreement needs to say clearly what happens to that IP.
Model B: Independent Contractor
The project keeps its own legal identity and enters a contractor relationship with the sponsor. The sponsor accepts tax-deductible donations, then pays the project to perform specific charitable services described in a written agreement. The project operates more independently than under Model A, but the sponsor still exercises enough oversight to ensure the work meets exempt-purpose standards. Because project workers are not the sponsor’s employees, Model B avoids the payroll and benefits load of Model A.
Model C: Pre-Approved Grant Relationship
The project stays a separate entity with its own governance, and the sponsor acts as a grantmaker rather than an employer. Donors give to the sponsor, and the sponsor grants those funds to the project to carry out agreed-upon charitable activities. Of the three common arrangements (A, B, and C), Model C gives the project the most operational independence. The sponsor still holds what practitioners call variance power, the discretion to redirect or withhold funds if the project drifts from its charitable mission. Without that discretion, the IRS would view the sponsor as a mere pass-through.1Internal Revenue Service. Revenue Ruling 68-489
Model D: Group Exemption
A parent organization extends its IRS-recognized exempt status to subordinate organizations that affiliate with it. Each project in the group gets its own employer identification number and can receive deductible donations directly, without filing a separate Form 1023. This structure is common among national organizations with local chapters. The parent keeps authority to add or remove subordinates from the group exemption, which provides structural oversight without the hands-on fund management of Models A through C.
Model E: Supporting Organization
A supporting organization is a separate legal entity that qualifies for exempt status under Section 509(a)(3) because it is organized and operated exclusively for the benefit of one or more publicly supported organizations. The IRS classifies these as Type I, Type II, or Type III based on the relationship. Type I means the supported organization appoints or elects a majority of the supporting organization’s board. Type II means the two share overlapping boards. Type III requires the supporting organization to be responsive to and significantly involved with the supported organization. Disqualified persons cannot control a supporting organization, which limits insider influence.2Internal Revenue Service. Supporting Organizations Requirements and Types Model E suits large, long-term projects that want their own corporate structure but benefit from a formal tie to an established charity.
Model F: Technical Assistance
Model F fits projects that already have their own 501(c)(3) status but need help with back-office work: bookkeeping, payroll processing, human resources support, tax return preparation. The sponsor does not receive or manage charitable funds and takes on no legal liability for the project’s activities. It’s the lightest arrangement and barely resembles traditional sponsorship, since the project handles its own fundraising and compliance.
What the Sponsor Is Required to Do
Revenue Ruling 68-489 sets the baseline. A sponsor can fund a non-exempt project’s charitable work only if it retains real control and discretion over how the money is spent and keeps records showing the funds served exempt purposes.1Internal Revenue Service. Revenue Ruling 68-489 In practice, the sponsor must review and approve budgets, monitor expenditures, and hold the authority to cut off funding if the project drifts. A sponsor that rubber-stamps disbursement requests risks being treated as a conduit, which strips the deductibility of donor contributions and can threaten the sponsor’s own exemption.
A sponsor can only take on projects that fall within its own exempt purpose as described in its organizing documents and IRS application. A health-focused nonprofit generally cannot sponsor a project whose primary activity is lobbying for housing policy unless its charter is broad enough to cover that work. This is why sponsors screen carefully and turn projects away even when the mission looks worthy in isolation. Supporting activities outside the sponsor’s approved scope can be treated as operating beyond its exempt purpose.
Section 4958 of the Internal Revenue Code adds another guardrail. It imposes excise taxes on “excess benefit transactions” between an exempt organization and its insiders. A disqualified person who receives compensation or other economic benefits exceeding the value of what they provided in return faces a tax of 25% of the excess benefit, rising to 200% if the transaction is not corrected.3Office of the Law Revision Counsel. 26 USC 4958 – Taxes on Excess Benefit Transactions In a sponsorship context, this matters most when a project leader has enough influence over the sponsor to qualify as a disqualified person and receives unreasonable pay or diverts project funds.
Rules Your Project Will Inherit
A sponsored project takes on the political and lobbying restrictions that apply to its 501(c)(3) sponsor. Some of these limits catch project teams off guard, so it’s worth understanding them before you sign.
The absolute rule: no participation in political campaigns for or against any candidate for public office. That covers donations to campaigns, endorsements, public statements of support or opposition, and any voter outreach conducted in a partisan manner. Violations can cost the sponsor its tax-exempt status and trigger excise taxes. Nonpartisan voter education, registration drives, and get-out-the-vote efforts are allowed, but only when conducted without bias favoring or opposing a candidate.4Internal Revenue Service. Restriction of Political Campaign Intervention by Section 501(c)(3) Tax-Exempt Organizations The line between education and advocacy can be thin, and a project that crosses it puts the entire sponsor at risk.
Lobbying is treated differently. Exempt organizations can engage in limited lobbying, and those that make a 501(h) election by filing Form 5768 get a clear expenditure-based test. The allowable spend is 20% of the first $500,000 of exempt-purpose expenditures, with a declining percentage on amounts above that, capped at $1,000,000 for organizations spending more than $17,000,000. An organization that exceeds its lobbying limit in a given year pays an excise tax of 25% on the excess, and consistently excessive lobbying over a four-year period can trigger loss of exempt status.5Internal Revenue Service. Measuring Lobbying Activity Expenditure Test The cap applies at the sponsor’s organizational level, so lobbying by any one project counts against the total shared with every other sponsored project.
Because donors are technically giving to the sponsor, the sponsor issues all tax-deductible acknowledgment letters. The IRS requires written acknowledgment for any single contribution of $250 or more, though most sponsors send receipts for smaller gifts too. A project that mails its own acknowledgments on its own letterhead creates confusion and potential compliance problems, since the project is not the exempt entity. Fundraising materials should clearly disclose the sponsorship relationship so donors understand where the money is going.
What the Agreement Should Cover
Administrative Fees
Most sponsors charge a fee calculated as a percentage of the funds they manage. The typical range runs 5% to 10%, with higher rates for complex projects involving government contracts or heightened reporting. The fee covers accounting, compliance, fund management, and whatever additional services the sponsor provides. Negotiate before signing; a few percentage points on a large grant is real money.
Budget and Financial Controls
The agreement should include a detailed, itemized budget showing how funds will be allocated. The sponsor uses it as the baseline for reviewing disbursement requests. Most sponsors set up a restricted fund account for each project to prevent commingling with general operating funds. The agreement should spell out who can authorize expenditures, what documentation is required, and how often the project must submit financial reports.
Intellectual Property and Assets
Under Model A, assets created or acquired during the sponsorship belong to the sponsor. That includes creative works, software, curricula, trademarks, and other intellectual property. The agreement needs to address what happens to those assets if the project eventually spins off. Without clear language, a project that spent years building a brand or developing content may have no legal claim to it on the way out. Models B and C generally leave IP with the project, but even then the agreement should say so plainly.
Termination and Asset Transfer
Every agreement needs a clear exit plan. When a project leaves a sponsor, whether to join a different sponsor or operate under its own newly obtained 501(c)(3), the two parties sign a transfer agreement covering assets and liabilities. Model A exits can get complicated: employees are terminated by the old sponsor and rehired by the new entity, accrued leave is paid out or assumed, IP is formally transferred. Model C exits are often simpler because the sponsor may hold minimal assets and can close the project’s account with a final grant to the successor organization.
If a project dissolves rather than transferring, charitable assets cannot go to private individuals. Remaining funds must go to another 501(c)(3) or back to the sponsor for use in furtherance of its exempt purpose.
Conflict of Interest Protections
The IRS recommends that all exempt organizations maintain a conflict of interest policy requiring anyone with a financial interest in a decision to disclose the facts and recuse themselves from voting.6Internal Revenue Service. Form 1023 Purpose of Conflict of Interest Policy In a sponsorship, conflicts show up when project leaders have personal or business ties to sponsor board members, or when the same people sit on both the project’s advisory committee and the sponsor’s board. The sponsor’s vetting process should screen for those relationships, and the agreement should incorporate the sponsor’s existing conflict of interest policy by reference.
How You Enter a Fiscal Sponsorship
A project usually begins by submitting a written application to the sponsor containing a mission statement, a description of planned activities, an itemized budget, and identification of key leaders. The sponsor’s board or a designated selection committee evaluates whether the project’s mission aligns with the sponsor’s exempt purpose, whether the budget is realistic, and whether the team can deliver. Review timelines vary widely with how often the board meets and how complex the project is.
Once approved, the parties execute a formal written agreement covering the sponsorship model, fee structure, reporting requirements, fund management procedures, IP ownership, and termination. The sponsor then sets up a restricted fund account, establishes a reporting schedule, and trains the project team on disbursement and documentation.
The relationship doesn’t end at signing. The sponsor continues to review financial reports, confirm that expenditures match the approved budget, and verify that the work still furthers its exempt purpose. The sponsor’s board stays legally accountable for the project’s activities, which is why meaningful ongoing oversight matters more than the initial approval vote. For projects, that means being prepared for real scrutiny, not just a permission slip to fundraise.
