Comprehensive vs. Light Fiscal Sponsorship (Model A vs. Model C): Which Fits Your Project?

A Practical Guide for Social Entrepreneurs, Nonprofit Leaders & Mission-Driven Innovators

Launching a social enterprise or nonprofit initiative is one of the most courageous and impactful things you can do. But after the excitement of your idea, the reality sets in: the administrative, legal, financial, and compliance requirements of running a charitable organization can be overwhelming — especially in the early stages.

That’s where fiscal sponsorship becomes one of the most strategic tools available to mission-driven founders. It helps you launch faster, reduce risk, and operate under the umbrella of an established 501(c)(3) rather than waiting months (or a year or more) to obtain tax-exempt status yourself.

But fiscal sponsorship isn’t one-size-fits-all.

Two of the most common models — Model A (“Comprehensive”) and Model C (“Pre-Approved Grant Relationship” or “Light”) — offer different structures, responsibilities, freedoms, and risks.

Understanding the difference isn’t just a legal technicality — it determines how your project operates, raises funds, hires people, and grows.

This guide breaks down both models to help you make the best decision for your project — and to illustrate how Angels for Angels supports mission-driven founders through either path.

What Is Fiscal Sponsorship? (Quick Overview)

Fiscal sponsorship allows a project without its own 501(c)(3) status to operate under the umbrella of an established nonprofit. The sponsor receives tax-deductible donations and provides financial oversight, legal compliance, and other administrative support while the project focuses on impact.

But the relationship structure — and how much control the sponsor has — varies dramatically between different models.

Model A: Comprehensive Fiscal Sponsorship

“The sponsor operates the project.”

Model A is the gold standard for initiatives that want deep support, risk management, and operational simplicity.

Under Model A:

How It Works

• The project becomes a program of the fiscal sponsor

• The sponsor is responsible for:

  • Financial management

  • Accounting & bookkeeping

  • HR & payroll

  • Legal compliance

  • Grants & contracts

  • Insurance & risk management

• The project’s staff, contractors, and assets legally belong to the sponsor.

Best For Projects That…

• Want to launch quickly with fully operational infrastructure

• Need administrative support (e.g., HR, grant management, payroll)

• Prefer to focus on mission, not back-office work

• Plan to hire staff or manage significant funds

• Need risk management and compliance built in

• Want to attract foundations that insist on strong oversight

Advantages

• Fast launch: Start fundraising immediately

• Strong funder credibility: Sponsors bring compliance + trust

• No need to build infrastructure: Everything exists already

• Lower legal & financial risk: Sponsor manages compliance

• Operational support: HR, payroll, benefits, accounting

Potential Limitations

• Less operational independence — the sponsor must formally approve budgets, hires, and agreements

• Project must operate under sponsor policies

• The sponsor is ultimately legally responsible

Who Typically Chooses Model A?

• Growing social enterprises

• Community-based programs

• Health, education, and human-services initiatives

• International development projects

• Grant-funded programs with strict compliance

• Founders who want to avoid administrative burdens

In short, Model A is ideal if you want to focus on your mission while a trusted partner handles the rest.

Model C: “Light” Fiscal Sponsorship

“The sponsor grants funds to an independent entity.”

Model C is better for founders who want independence and are capable of managing their own finances, operations, and compliance — while still accessing tax-deductible donations.

How It Works

• The project is operated by a separate legal entity (LLC or unincorporated group)

• The fiscal sponsor receives donations and grants

• The sponsor re-grants funds to the project

• The project handles:

  • Operations

  • Financials

  • Contracts

  • HR

  • Compliance

• The sponsor must ensure funds are used for charitable purposes.

Best For Projects That…

• Already have operational capacity

• Want maximum independence

• Have separate business structures or for-profit components

• Need fiscal sponsorship only to receive charitable funds

• Are short-term, event-based, or hyper-focused

Advantages

• More autonomy in day-to-day operations

• Lower fee structure than comprehensive sponsorship

• The project can operate with entrepreneurial flexibility

• Good for hybrid or for-profit social enterprise models

Potential Limitations

• More administrative burden for the project

• The project carries legal and compliance risks

• Less funder trust (compared to Model A)

• Can't use sponsor HR or payroll

• Requires more sophisticated founders

Who Typically Chooses Model C?

• Experienced founders are comfortable managing operations

• Event-based initiatives

• Film/documentary projects

• Short-term programs

• Social enterprises blending charitable and business activities

In short, Model C is ideal for independent founders who want fiscal sponsorship without operational oversight.

How to Choose the Right Model for Your Project

Ask yourself the following questions:

1. What is my operational capacity?

If you lack accounting, HR, or compliance expertise, Model A is safer.

2. How fast do I need to launch?

Model A allows a near-instant start.

3. Who are my funders?

Foundations generally prefer Model A for oversight.

4. Do I need to hire staff?

Model A simplifies this dramatically.

5. Do I want independence above all?

Model C gives full autonomy.

6. Am I building something long-term?

Model A supports scale more easily.
