Fiduciary Duty 101: A Beginner’s Guide to Mastering Your Role for Another Org

Fiduciary Duties in Fiscal Sponsorship

If your nonprofit is serving as a fiscal sponsor, your board’s responsibilities go far beyond approving a good idea and moving on. Fiscal sponsorship can be a powerful way to support community-led work, but it only works well when the sponsoring organization maintains clear oversight, strong systems, and a deep commitment to its mission.

That is where fiduciary duty comes in.

Every nonprofit board has three core fiduciary duties: care, loyalty, and obedience. These duties shape how board members make decisions, manage risk, and protect the organization. In a fiscal sponsorship arrangement, they also help ensure the sponsor meets the IRS expectation that it retains full “control and discretion” over charitable funds.

Why Fiduciary Duties Matter

Board service is not just honorary. It comes with legal and ethical responsibility.

When a nonprofit board understands its fiduciary role, it is better equipped to make sound decisions, ask the right questions, and protect the organization from avoidable compliance issues. In fiscal sponsorship, that matters because the sponsor is not simply holding funds for someone else. The sponsor is responsible for making sure those funds are used in a way that aligns with its own charitable purpose and applicable law.

In other words, fiscal sponsorship is not passive. It requires active governance.

The Three Fiduciary Duties

Duty of Care

The duty of care means board members should act with reasonable care, good faith, and sound judgment. They are expected to stay informed and take their role seriously.

In practical terms, this usually means:

Attending board and committee meetings

Reviewing budgets, financial statements, and key agreements

Paying attention to legal, financial, and reputational risks

Making sure financial controls and approval processes are in place

For smaller nonprofits, this duty can feel especially important because there may be limited staff capacity. Even so, the board cannot afford to operate on assumptions. Asking questions, reviewing reports, and understanding how funds move through the organization are all part of good governance.

Duty of Loyalty

The duty of loyalty means board members must put the organization’s best interests first. Personal relationships, outside roles, and donor preferences should never outweigh what is best for the nonprofit and its mission.

This includes:

Disclosing conflicts of interest

Avoiding personal gain from board service

Protecting confidential information

Preventing improper private benefit or inurement

This duty becomes especially relevant in community-based work, where leaders often wear multiple hats. A board member may also be connected to a sponsored project, a donor, or a partner organization. That does not automatically create a problem, but it does require transparency and proper boundaries.

Duty of Obedience

The duty of obedience means the board must make sure the organization follows the law, honors its governing documents, and stays aligned with its stated mission.

That includes making sure the nonprofit:

Complies with applicable laws and regulations

Follows its bylaws, policies, and internal procedures

Operates within its charitable purpose

Uses donor-restricted funds as promised

This duty is often overlooked, but it is essential. A nonprofit cannot say yes to every good cause if that work falls outside its legal or mission-based scope.

What “Control and Discretion” Means in Fiscal Sponsorship

When a 501(c)(3) acts as a fiscal sponsor, donors often give with the understanding that the funds will support a specific project. But for those contributions to remain charitable donations to the sponsor, the sponsor must maintain full control and discretion over how the funds are used.

That means the sponsor must do more than receive money and pass it through.

The sponsor should:

Decide how funds are used in alignment with its exempt purpose

Maintain oversight of project budgets, spending, and activities

Require reports and documentation

Retain the authority to withhold, redirect, or stop funding if needed

If the sponsor simply acts as a pass-through based on donor instruction or project demands, the arrangement can create serious legal and tax concerns. Put simply, the sponsor must remain the decision-maker.

How the Three Duties Apply to Fiscal Sponsorship

Duty of Care in Fiscal Sponsorship

In a fiscal sponsorship relationship, the duty of care calls the board to build and monitor a structure that actually works.

That may include:

Approving the organization’s fiscal sponsorship policy

Deciding which sponsorship model the organization will use

Reviewing sponsorship agreements or setting approval thresholds

Evaluating whether a project fits the mission and capacity of the sponsor

Monitoring budgets, reporting, and financial controls for each sponsored project

This is what real oversight looks like. If the board is not reviewing risks, understanding how funds are being spent, and checking whether systems are being followed, it is not fully meeting its duty of care.

Duty of Loyalty in Fiscal Sponsorship

The duty of loyalty helps the board stay clear about whose interests come first.

In fiscal sponsorship, that means the board must prioritize the sponsoring organization’s mission and legal responsibilities, even when a donor, project leader, or partner wants something different.

This may involve:

Managing conflicts when board or staff members are connected to a sponsored project

Requiring disclosures and recusals when needed

Making sure payments to project leaders or related parties are reasonable and documented

Avoiding donor arrangements that give outside parties too much control over charitable funds

This matters because fiscal sponsorship can easily become blurry if boundaries are not clear. Loyalty helps the board stay grounded.

Duty of Obedience in Fiscal Sponsorship

The duty of obedience is often the clearest link between governance and compliance.

In a sponsorship arrangement, the board should make sure:

The project fits within the sponsor’s charitable purpose

Activities follow applicable laws, including rules around employment, fundraising, advocacy, and charitable solicitation

Internal policies apply to sponsored projects, not just to core operations

Noncompliant projects are corrected, paused, or ended when necessary

If a project starts drifting away from the sponsor’s mission or refuses to follow required procedures, the board cannot ignore it. Obedience requires action.

Practical Steps for Boards

If your organization is acting as a fiscal sponsor or thinking about it, here are a few practical steps that can strengthen both governance and compliance:

Adopt a written fiscal sponsorship policy

Make it clear how projects are approved, supervised, and, if necessary, closed.

Use a strong fiscal sponsorship agreement

The agreement should clearly state that the sponsor retains control and discretion over funds and outline reporting, spending, and compliance expectations.

Keep project finances clearly tracked

Separate accounting helps the board and staff monitor each project responsibly.

Apply conflict-of-interest procedures consistently

Disclosures and recusals should be documented when relationships overlap.

Put fiscal sponsorship on the board agenda

Regular reporting keeps the board informed and helps catch issues early.

Final Thought

Fiscal sponsorship can be a meaningful tool for supporting new ideas, emerging leaders, and community-based work. But it should never be treated casually. Strong fiscal sponsorship depends on strong governance.

When a board understands the duties of care, loyalty, and obedience, it is in a much better position to protect the organization, support sponsored projects responsibly, and stay compliant with IRS expectations.
