A board of trustees is the governing body that holds legal title to a nonprofit, foundation, or institution’s assets and manages them for the organization’s beneficiaries rather than for personal gain. The board of trustees roles and responsibilities fall into a few concrete categories: three fiduciary duties enforced by courts and the IRS, oversight of the chief executive, financial stewardship, compliance with federal reporting rules, and management of the organization’s beginning, direction, and eventual end. Trustees can be held personally liable when they fall short, and federal tax law can impose excise taxes of 25 to 200 percent on individuals involved in self-dealing.
The Three Fiduciary Duties
Every trustee owes the organization three fiduciary duties. These are legal obligations, not aspirations, and breaching any one of them can lead to personal liability.
Duty of Care
You have to make decisions the way a reasonably careful person would in your position. That means attending meetings, reading financial reports before voting on them, and asking questions when something looks wrong. Rubber-stamping decisions without reviewing the underlying information is a breach. Courts that find gross negligence can hold a trustee personally responsible for the resulting losses.
Duty of Loyalty
The organization’s interests come before yours. If a transaction could benefit you personally, you disclose the conflict and step out of the vote. Federal tax law enforces this with real penalties: when a “disqualified person” such as a board member or executive receives an excessive benefit from the organization, the IRS can impose an excise tax of 25 percent of that benefit, rising to 200 percent if the transaction isn’t corrected within the allowed period.1Office of the Law Revision Counsel. 26 U.S. Code 4958 – Taxes on Excess Benefit Transactions
Duty of Obedience
Trustees must keep the organization tied to its stated charitable purpose and governing documents. You can’t redirect resources toward activities outside the articles of incorporation, no matter how worthwhile they seem. Straying from the mission can trigger IRS review that leads to loss of tax-exempt status, or a state attorney general investigation into misuse of charitable assets.
Hiring, Evaluating, and Paying the Executive
The board sets long-term direction, but it does not run day-to-day operations. This is where new trustees often overreach. Your job is to hire and evaluate the chief executive, not to manage staff or make project-level decisions.
Setting executive compensation is one of the board’s most consequential recurring tasks. Federal tax law penalizes organizations that pay leaders unreasonably. The IRS looks more favorably on compensation decisions made through what’s called the rebuttable presumption of reasonableness: the board or an independent committee reviews comparable salary data, deliberates without the executive present, and documents the decision in the meeting minutes. Following the process doesn’t guarantee IRS agreement on the amount, but it shifts the burden of proof to the IRS to show the compensation was excessive.2Internal Revenue Service.

Boards also periodically reassess the mission statement so the organization can adapt to changing needs without drifting into activities the IRS may view as inconsistent with its exempt status.
Financial Oversight
The board approves the annual operating budget and monitors financial performance through the year. Organizations that hold endowments manage those funds under the Uniform Prudent Management of Institutional Funds Act, adopted in most states, which requires investment decisions made in good faith and with the care a prudent person would exercise.
Strong internal controls are where most fraud prevention actually happens. Requiring dual signatures on checks above a set threshold, separating the people who authorize payments from those who process them, and commissioning annual independent audits all reduce embezzlement risk. When someone steals from a nonprofit receiving federal funds, federal law provides for a prison sentence of up to 10 years and substantial fines.3Office of the Law Revision Counsel. 18 U.S. Code 666 – Theft or Bribery Concerning Programs Receiving Federal Funds
Fundraising is often part of the role. Many boards expect trustees to contribute personally and to open their networks to donors. Those expectations should be spelled out during recruitment.
Managing Conflicts of Interest
The IRS asks every organization on its annual Form 990 whether it has a written conflict of interest policy. The tax code doesn’t technically require one, but operating without a policy is a red flag. The IRS publishes a sample policy that most organizations adapt.
An effective policy covers:
- Disclosure of any financial interest in a proposed transaction, along with all material facts, before the board discusses the matter.
- Recusal of the interested trustee from both the discussion about whether a conflict exists and the vote itself.
- Investigation of alternatives from someone who doesn’t present a conflict. If none exists, a majority of disinterested members must vote that the arrangement is fair and reasonable.
- Documentation in meeting minutes of who disclosed a conflict, what alternatives were considered, who voted, and the outcome.
- Annual written affirmation from each trustee confirming they’ve read, understood, and agreed to follow the policy.
Boards that skip these steps lose the procedural protection that helps defend against excess-benefit claims under federal tax law.
Tax Filings and Public Disclosure
The board is responsible for making sure the organization files its annual return with the IRS. Which form applies depends on size. Private foundations file Form 990-PF regardless of revenue. Among other exempt organizations, the smallest (generally with gross receipts of $50,000 or less) file the electronic 990-N notice; mid-size organizations file Form 990-EZ; and organizations with gross receipts of $200,000 or more, or total assets of $500,000 or more, file the full Form 990.4Internal Revenue Service.

Missing this filing for three consecutive years triggers automatic revocation of tax-exempt status. Revocation takes effect on the filing due date of the third missed return, and the organization must reapply for exemption from scratch. Churches and their integrated auxiliaries are exempt from the filing requirement; almost every other 501(c)(3) is not.5Internal Revenue Service.

Federal law also requires nonprofits to make their three most recent annual returns and their original exemption application (Form 1023) available on request. In-person requests must be fulfilled immediately; written requests within 30 days. The organization may charge only a reasonable fee for photocopying and postage.
How Trustees Are Chosen and How Long They Serve
How trustees come onto a board depends on the type of organization. Self-perpetuating boards, common at private nonprofits and foundations, elect their own replacements, with current members recruiting people who bring complementary skills in finance, law, or the organization’s area of service. Public university boards work differently: in most public systems, the governor appoints trustees and the state senate confirms them.
Term lengths vary. Private nonprofit boards often set three- or four-year terms in their bylaws. Public university trustees tend to serve longer, with terms at some systems reaching 12 years. Many organizations impose term limits to prevent entrenchment; others resist limits because long-serving members carry institutional memory that’s hard to replace.
Board composition matters as much as individual credentials. A board weighted toward finance professionals but lacking anyone who understands the population the organization serves will make technically sound decisions that miss the point.
Closing the Organization Down
When an organization shuts down, the board manages the process and bears legal responsibility for doing it correctly. Federal tax law requires 501(c)(3) organizations to include a dissolution clause in their governing documents directing remaining assets to another exempt purpose, another 501(c)(3), or a federal, state, or local government for a public purpose.6Internal Revenue Service. Does the Organizing Document Contain the Dissolution Provision Required Under Section 501(c)(3)
No trustee or private individual can pocket what’s left. The board must settle outstanding liabilities first, then distribute remaining assets according to the dissolution clause. The IRS requires a dissolved organization to file a final Form 990, including Schedule N, which details what assets were distributed, their fair market value, and who received them. Most states also require notification or approval from the state attorney general before dissolution is finalized, particularly when charitable assets are involved. Skipping any of these steps can expose individual trustees to liability long after the organization has ceased to exist.
Personal Liability and How Trustees Are Protected
The exposure that comes with board service is real, but federal and state law offer meaningful protection for trustees who act in good faith.
The federal Volunteer Protection Act of 1997 provides qualified immunity to uncompensated volunteers serving nonprofits. If you’re not paid for your service and you act within the scope of your responsibilities, you generally cannot be held personally liable for ordinary negligence. That protection disappears for gross negligence, willful misconduct, or reckless indifference to someone’s safety. Some states also require the nonprofit to carry liability insurance before the immunity applies.
Most well-run organizations carry Directors and Officers (D&O) insurance, which covers defense costs and settlements when board members face claims arising from governance decisions. Coverage typically extends to current and former trustees, officers, employees, and volunteers. Going without it leaves every board member exposed to out-of-pocket legal costs even when they’ve done nothing wrong.
