Fiscal Sponsorship vs. Starting a Nonprofit: Form 990 Rules

You have a program idea, a few committed volunteers, and maybe a first donor asking where to send a check. Fiscal sponsorship is an arrangement in which an established 501(c)(3) organization takes legal and tax responsibility for a charitable project, so the project can receive tax-deductible donations without its own tax-exempt status. The alternative is forming an independent nonprofit and applying for exemption yourself.

Choosing between fiscal sponsorship vs. starting a nonprofit comes down to who holds legal responsibility, who reports to the IRS, and how much control your team keeps. Both paths are legitimate, and both can serve a mission well. Here’s how they compare.

What Fiscal Sponsorship Means Structurally

A fiscal sponsor is an established 501(c)(3) organization that agrees to take on a charitable project that fits its own exempt purposes. The sponsor holds the legal and tax responsibility for that project. Donors give to the sponsor, which is why their gifts are deductible under IRC Section 170(c), and the sponsor’s governing body keeps final authority over how those funds are used. 

The Two Most Common Sponsorship Models

• Comprehensive or direct project sponsorship (Model A): The project becomes a program of the sponsor. It has no separate legal identity, its finances run through the sponsor’s books, and its staff are often the sponsor’s employees.
• Preapproved grant relationship (Model C): The project operates as its own entity and receives grants from the sponsor. The sponsor must keep discretion and control over the granted funds and make sure they’re spent on charitable purposes. 

In exchange for carrying that responsibility, sponsors typically charge an administrative fee, usually a percentage of the funds the project raises. The written sponsorship agreement should spell out the fee, reporting expectations, and what happens to the funds if the relationship ends.

Who Files Form 990 in a Fiscal Sponsorship Arrangement?

In a fiscal sponsorship arrangement, the fiscal sponsor files Form 990 and reports the sponsored project’s revenue and expenses as its own. The sponsored project doesn’t file a separate Form 990 because it has no tax-exempt status of its own. That means no Form 990, Form 990-EZ, or Form 990-N for the project under a comprehensive arrangement.

That’s a large part of the appeal. The project team focuses on programs while the sponsor handles accounting, donor acknowledgments, and IRS reporting. If you want a closer look at how different income streams are reported, read our guide to nonprofit revenue types and the tax rules behind each one.

Under a preapproved grant relationship, the sponsor reports the grants it makes, which may include Schedule I for larger grants to domestic organizations. A project that’s a separate legal entity without its own exemption may have filing obligations of its own, so it’s worth confirming its status with a tax professional.

Fiscal Sponsorship Reporting Is Under Review

In April 2026, the U.S. Department of the Treasury announced a Form 990 transparency initiative that includes fiscal sponsorship arrangements. Treasury has said it will release proposed regulations and invite public comment before changing any reporting requirements. Sponsors and sponsored projects should keep their agreements, grant records, and financial documentation current in the meantime.

Fiscal Sponsorship vs. Starting a Nonprofit at a Glance

	Fiscal sponsorship	Independent nonprofit
Setup time	Often a few weeks, once the agreement is signed	Several months, including state incorporation and IRS review
Upfront cost	Low, with an ongoing fee on funds raised	State incorporation fees and the Form 1023 user fee
Governance control	Sponsor’s governing body has final authority	Your own board sets strategy and spending
Who files Form 990	The sponsor	Your organization
Legal liability	Sponsor (comprehensive model)	Your organization
Ongoing administration	Sponsor handles accounting and reporting	Your team owns compliance

Factors That Favor Fiscal Sponsorship

• Speed: A project can often begin accepting deductible gifts once the sponsorship agreement is signed, instead of waiting on an IRS determination letter.
• Testing an idea: Sponsorship works well for pilot programs, time-limited campaigns, and projects still proving their model.
• Limited administrative capacity: If you don’t yet have a board, bookkeeping, or someone to own compliance, a sponsor provides that infrastructure.
• Startup costs: You avoid incorporation fees, the Form 1023 user fee, and annual state registrations until you’re ready for them.

Factors That Favor Forming an Independent Nonprofit

• A long-term, growing program: As your budget grows, a percentage-based fee grows with it, and independence may cost less over time.
• Governance control: An independent organization has its own governing body, which sets strategy and makes final spending decisions.
• Funder expectations: Some grantmakers prefer, or require, applicants to hold their own IRS determination letter.
• Building your own record: Independence lets your organization develop its own public support history and financial track record under its own EIN.

What Changes When Your Organization Files Independently

Leaving sponsorship means taking on the responsibilities your sponsor used to carry. Most organizations will need to incorporate at the state level, obtain an EIN, and apply for recognition of exemption on Form 1023 or Form 1023-EZ. Once the IRS approves your application, learn how to read your IRS determination letter so you know your classification and filing requirements.

After recognition, your organization files an annual return based on its size. 

Form	Gross receipts	Total assets
Form 990-N (e-Postcard)	Normally $50,000 or less	Not applicable
Form 990-EZ	Under $200,000	Under $500,000
Form 990	$200,000 or more	Or $500,000 or more

Filing every year matters. An organization that doesn’t file for three consecutive years automatically loses its tax-exempt status. Check the Form 990 filing due date for your fiscal year to plan your first filing season.

Frequently Asked Questions About Fiscal Sponsorship

Does a Fiscally Sponsored Project File Its Own Form 990?

Not under a comprehensive sponsorship. The sponsor reports the project’s activity on its own return. Under a preapproved grant relationship, the sponsor reports the grants it makes, and the project may have separate obligations depending on its legal status.

Does a Fiscally Sponsored Project Need Its Own EIN?

A comprehensive project usually operates under the sponsor’s EIN because it’s legally part of the sponsor. A project in a preapproved grant relationship is its own entity, so it typically has its own EIN. 

What Happens to the Funds When a Project Leaves Its Sponsor?

The funds legally belong to the sponsor, so the sponsorship agreement governs what happens next. A common approach is for the sponsor to grant remaining funds to the new 501(c)(3) once it receives recognition of exemption.
