How To Set Up A Fiscal Sponsorship Agreement?

To set up a fiscal sponsorship agreement, choose a sponsorship model, confirm the sponsor’s mission matches your project, and sign a written contract that gives the sponsor legal control over donations before your first fundraising appeal goes out.

The contract covers 11 areas, from variance power and fees to who keeps the donor list at exit. Clear control language protects your sponsor’s tax-exempt status and your donors’ deductions.

TL;DR

• Under Rev. Rul. 68-489, a 501(c)(3) can fund a project that has yet to earn its own tax-exempt status when the charity keeps control and discretion over the money and records showing charitable use.
• Model C, the preapproved grant relationship, is offered by 63% of the 376 sponsors in the Fiscal Sponsor Directory, and Model A by 46%.
• Of the sponsors in the directory, 96% charge a percentage of project revenue. The most common range is 5% to 10%, and fees of 15% or more usually apply to projects funded by government grants.
• A fiscal sponsorship agreement protects donor deductions when the sponsor exercises discretion over every payment. The IRS can treat gifts forwarded on autopilot as made to the project itself.
• H.R. 9721, the Fiscal Sponsorship Transparency Act of 2026, cleared the House Ways and Means Committee by a 23-to-15 vote on July 22, 2026, and awaits a full House vote and Senate action. Its rules would start with tax years beginning after December 31, 2027.

What A Fiscal Sponsorship Agreement Decides

A fiscal sponsorship agreement is a written contract in which an established 501(c)(3) public charity receives tax-deductible donations for a charitable project and keeps legal control over how that money is used. Your project gains the sponsor’s tax-exempt status for fundraising, and the sponsor takes legal responsibility for the charitable use of every dollar.

Fiscal sponsorship rests on IRS rulings and practice, and the Internal Revenue Code and Treasury regulations leave the term undefined, according to the Joint Committee on Taxation. Your contract defines the rules of your arrangement.

Older contracts call the sponsor a “fiscal agent.” The field moved to “fiscal sponsor” after attorney Gregory Colvin’s 1993 book, Fiscal Sponsorship: 6 Ways To Do It Right, because a sponsor carries legal responsibility and keeps discretion and control over the funds.

Model A suits projects that have not yet formed a legal entity, because the project becomes a program of the sponsor. Model C usually works with a separate organization, such as a nonprofit corporation waiting on its IRS determination letter.

Step 1: Choose Between Model A and Model C

Choose Model A when you want the sponsor to run your back office, and Model C when you already have an organization and want to run your own operations. Colvin’s book describes six models, and these two cover most arrangements.

Name your chosen model in your fiscal sponsorship agreement, since the model sets who owns funds, who employs staff, and who signs contracts. Model A gives your project full back office support from the sponsor. Model C gives your project operating independence, and 16% of sponsors in the Fiscal Sponsor Directory offer both.

We recommend Model C for projects that already have a legal entity, insurance, and someone to run payroll. Projects still building those pieces do well with Model A in their first year. Model C also suits projects planning their own 501(c)(3) soon, because closing a grant relationship makes a clean exit. Under Model A, staff, contracts, and assets all move out of the sponsor at exit.

Step 2: Vet The Fiscal Sponsor Before You Sign

Mission fit decides most applications to a fiscal sponsor. In the Fiscal Sponsor Directory, 87% of sponsors name-aligned mission and values as their main criterion for accepting a project, and 43% require projects to operate in their area.

Work through these steps before you negotiate terms:

1. Confirm the sponsor’s 501(c)(3) public charity status in the IRS Tax Exempt Organization Search.
2. Ask for its written sponsorship policies and a sample fiscal sponsorship agreement.
3. Get the fee schedule in writing, along with the list of services the fee covers.
4. Ask how long a disbursement request takes and who approves it.
5. Prepare your side: a project description, a first-year budget, leadership bios, and your expected funding sources.

Individuals and for-profit companies can sometimes be sponsors when the activity is charitable and furthers the sponsor’s exempt purpose. Sponsor policies vary, so ask early and bring in a nonprofit attorney for any arrangement where funds reach a for-profit company.

The Fiscal Sponsor Directory lists 376 sponsors hosting 20,566 projects as of its May 2024 update, with filters for state and service category.

Step 3: Draft The 11 Clauses Every Fiscal Sponsorship Contract Needs

Ask the sponsor for its standard agreement and check it against these 11 clauses with your attorney before you sign. A strong fiscal sponsorship agreement settles each question below.

1. Parties and Charitable Purpose

List both organizations’ full legal names, the sponsor’s 501(c)(3) status, and one sentence on how the project furthers the sponsor’s exempt purpose.

2. Model and Scope Of Activities

Name the model in the fiscal sponsorship contract. Attach the approved activities as an exhibit, and require written approval before the project adds new ones.

3. Variance Power

Variance power is the sponsor’s right to redirect donated funds to another charitable purpose if your project’s original purpose ends or becomes unlawful. This clause shows the sponsor holds genuine discretion. Example wording for your attorney to adapt: “All contributions received for the Project are assets of Sponsor. Sponsor retains discretion and control over their use and may redirect them to another charitable purpose if the Project’s purpose becomes impossible or unlawful to carry out.”

4. Ownership and Release Of Funds

State that the sponsor legally owns all donations. Then set the request process: who submits, what receipts or invoices are required, and how many business days a payment takes.

5. Fees and The Services They Buy

Most sponsors charge 5% to 10% of project revenue. Some 55 directory sponsors charge 15% or more, usually for projects funded by government grants that must meet federal audit standards. Government grants usually list the sponsor as the applicant or legal recipient, so build that rate into the grant budget. Write down whether the fee applies to all revenue or to donations only, and when it is deducted. Compare what each fee buys: nearly 3 in 4 sponsors include bookkeeping and bill paying, and over a third run payroll.

6. Fundraising and Grant Applications

Solicitations go out in the sponsor’s name. Name who approves appeals and who signs grant applications.

7. Reporting and Recordkeeping

Set how often the project sends financial and narrative reports, in what format, and confirm the sponsor’s right to inspect project records.

8. Taxes and Compliance

The sponsor reports sponsored funds on its own Form 990. The contract assigns charitable solicitation registrations, lobbying limits, and the rules on political campaign activity.

9. Staff, Liability and Insurance

Say who employs whom, which insurance each party carries, who indemnifies whom, and whether the project can sign contracts that bind the sponsor.

10. Intellectual Property and Donor Data

Decide who owns the project name, website domain, content, and donor list, both during the sponsorship and after it ends.

11. Term, Termination and Transfer

Set the notice period, the grounds for early termination, and where unspent restricted funds go. A clean exit clause lets the sponsor transfer remaining funds, assets, and grant agreements to the project’s new 501(c)(3) or to a successor sponsor, with the sponsor’s approval. Under Model C, the sponsor can grant remaining funds to the new 501(c)(3). Tell donors and funders your new legal name and EIN before your next appeal.

Step 4: Prove The Sponsor Exercises Discretion and Control

A fiscal sponsorship agreement holds up when the sponsor exercises discretion over the money in daily practice. Rev. Rul. 68-489 allows a 501(c)(3) to distribute funds to organizations outside section 501(c)(3) when it limits distributions to projects that further its own exempt purposes, keeps control and discretion over their use, and keeps records proving charitable use. When a sponsor acts as a mere conduit, the IRS can treat each gift as made straight to the project, and the deduction then depends on the project’s own status.

Picture a neighborhood food project that raises $60,000 through a sponsor. In version one, the sponsor wires each gift onward the week it arrives, and the file holds only bank transfers. In version two, the sponsor approves a budget first, releases money against invoices, and declines a $4,000 request outside the budget. Version two leaves a clear paper trail of control.

Congress wants that paper trail on record. H.R. 9721, the Fiscal Sponsorship Transparency Act of 2026, would require 501(c)(3) sponsors to report each arrangement’s parties, amounts, activities, managing officer and start and end dates. The version the House Ways and Means Committee approved by a 23-to-15 vote on July 22, 2026 sets a 20% excise tax on amounts knowingly transferred under an “improper conduit arrangement,” a 100% tax on transfers left uncorrected, and a 5% tax, capped at $10,000, on managers who knowingly approve one. As of October 2026, the bill awaits a full House vote and Senate action.

Treasury announced in April 2026 that it plans revised Form 990 reporting for fiscal sponsorship. Nonprofit law firm Perlman & Perlman advises sponsors to review their agreements now and confirm they document the sponsor’s discretion and control over sponsored funds.

Step 5: Set Up Controls Before The First Donation

Have authorized signers from both organizations sign the fiscal sponsorship agreement before public fundraising starts. For Model C, both organizations’ authorized leadership approves the arrangement.

Then put the controls in place: a separate ledger or bank account for each sponsored project, a written approval workflow for spending, a calendar of report due dates, and donor acknowledgments issued by the sponsor. Donors make gifts payable to the sponsor, which keeps donations tax-deductible for eligible donors. A “retains discretion” clause protects everyone once every payment runs through approval.

How Crowded Supports Fiscal Sponsors and Sponsored Projects

Crowded, a compliant money movement and banking platform for mission-driven organizations, gives fiscal sponsors a dedicated fund account for each sponsored project, so each project’s donations and spending sit in its own account.

Sponsor staff get a combined view across every sponsored project, and each project lead gets a personal login with role permissions. Policy controls stop spending outside your policy before money moves, and statements for each fund give your auditor a record that backs up the control terms in your fiscal sponsorship agreement.

Projects looking for a sponsor can apply to Crowded Foundation, a separate 501(c)(3) public charity that currently offers Model C sponsorship. Its team reviews applications within 5 business days.

Your attorney drafts and reviews the agreement, and Crowded works alongside your attorney, accounting software, and donor CRM. Before you sign, map where each sponsored project’s money will sit and who approves its spending.
