Board duties

Nonprofit board duties, explained

What state law expects of directors, how the IRS asks about governance on Form 990, and how to split the work between the board, the officers and the staff.

Six nonprofit board members of varied ages talking around a table in a library meeting room.

A nonprofit corporation has no owners. The board of directors is the group the law holds responsible for making sure the organization's money and property are used for its mission. That responsibility is real even when every director is an unpaid volunteer and the organization has a budget of a few thousand dollars.

This guide covers what directors owe the organization, how big and how independent a board should be, what the IRS asks about governance each year, and how to keep the board's job separate from the staff's.

Where board duties come from

State law, not the IRS. Your nonprofit is a corporation formed under the law of one state (see articles of incorporation). That state's nonprofit corporation statute, its court decisions and its attorney general set the standards for directors. The IRS cares about governance because weak oversight leads to tax problems, but it does not define fiduciary duties.

A fiduciary is a person in a position of trust who must act for someone else's benefit. Directors are fiduciaries of the corporation. State attorneys general commonly describe three duties. The Minnesota Attorney General's guide for board members, for example, lists the duties of care, loyalty and obedience to the law. Other states use similar words but differ on details, such as who can sue a director or how conflicts must be approved.

Duty of care

The duty of care asks you to act in good faith, in a way you reasonably believe is in the organization's best interest, and with the care an ordinarily prudent person would use in a similar position. In practice:

  • Attend meetings and read the materials before you arrive.
  • Review financial statements and ask questions until you understand them.
  • Make sure there are basic internal controls, such as two people involved in approving and paying bills.
  • Follow up on warning signs, such as a missed payroll tax deposit or a complaint about misuse of funds.

You can rely on reports from officers, committees and outside professionals, but you still have to oversee them.

Duty of loyalty

The duty of loyalty means you put the organization's interests ahead of your own. You do not use your position, or the organization's property, for personal gain or to benefit your family or your business. When a decision could benefit you, you disclose it and step back from the vote. A written conflict of interest policy turns this duty into a routine.

Loyalty is also where federal tax law adds teeth. Paying an insider more than fair value can be an excess benefit transaction with excise taxes on the insider and on the managers who approved it. See private benefit and excess benefit.

Duty of obedience

The duty of obedience means following the organization's governing documents, staying within its stated mission, and complying with the law. That includes filing the annual IRS return, keeping state registrations current and spending restricted gifts as the donor directed. Minnesota's guide notes that directors also have a duty to keep the corporation in good standing with the secretary of state.

Board size and independence

Federal law sets no minimum. The IRS does not require a particular number of directors. Some states do. New York's Not-for-Profit Corporation Law section 702 says the board must have at least three directors. Check your state's statute before you write the number into your bylaws.

More than the minimum is often wiser. A board of three can work for a very small organization, but it leaves little room for a director to step out of a vote when there is a conflict. A board of five to nine directors is easier to run well: it can still act when one or two people are unavailable or have to step out of a vote.

Independence matters to the IRS. Publication 4221-PC says the board should include independent members and should not be dominated by employees or by people who are not independent because of business or family relationships. On Form 990, a voting member counts as "independent" only if, for the whole tax year:

  1. They were not paid as an officer or employee of the organization or a related organization.
  2. They did not receive more than $10,000 as an independent contractor (other than reasonable pay for serving as a director).
  3. Neither they nor a family member had a transaction with the organization that must be reported on Schedule L.
  4. Neither they nor a family member had a similar reportable transaction with a related organization.

Being a donor, even a large one, does not by itself make a director non-independent.

What Form 990 asks about governance

Organizations that file the full Form 990 answer Part VI, "Governance, Management, and Disclosure." (Organizations that file Form 990-EZ or 990-N do not complete Part VI; see annual filing requirements for which return applies.) Section B of Part VI says it asks about policies that the Internal Revenue Code does not require. You can answer "No" without breaking a rule, but the answers are public, and donors, grantmakers and state regulators read them.

Part VI question What it is asking
Lines 1a and 1b Number of voting directors, and how many are independent
Line 2 Family or business relationships among officers, directors and key employees
Line 4 Significant changes to governing documents since the last return
Line 5 Whether you learned of a significant diversion of assets
Lines 8a and 8b Whether board and committee meetings were documented at the time
Line 11a Whether the board received a copy of the Form 990 before filing
Lines 12a to 12c Written conflict of interest policy, annual disclosures, and monitoring
Lines 13 and 14 Written whistleblower and document retention policies
Line 15 Whether pay for the top official and other officers was set using independent review, comparability data and written records
Line 19 Whether governing documents, the conflict policy and financial statements are available to the public

A board that holds documented meetings, adopts the three common policies and reviews the return before it is filed can answer most of these questions with a plain "Yes." For a walk-through of the full return, see Form 990, explained on our sister site.

Officers and what they do

Officers are the people the board appoints to carry out specific roles. Your bylaws name them and describe their duties. The usual set is:

  • President or chair: runs board meetings and often acts as the organization's main signer. Some organizations split this into a board chair and a separately titled chief executive.
  • Secretary: keeps minutes, notices of meetings and the corporate records. See nonprofit recordkeeping.
  • Treasurer: oversees finances, presents financial reports to the board and makes sure tax filings happen.

State law may limit how offices are combined. New York, for example, allows one person to hold two or more offices but not both president and secretary. New York also bars an employee from serving as board chair unless two-thirds of the entire board approves and the basis is documented in writing.

Board versus staff

The board governs; the staff manages. The board adopts the budget, sets policy, hires and evaluates the executive director, approves major contracts and checks results. The executive director and staff run programs, hire other staff, and make daily decisions within the budget and policies.

Founders who stay on the board need extra care here. A founder who is also the paid executive director reports to a board on which they also vote. That arrangement is common and is permitted in many states (New York, for example, lets the bylaws make officers ex-officio board members), but it weakens oversight unless the other directors are genuinely independent and the founder steps out of decisions about their own pay. See paying founders and staff.

When one person holds all the knowledge

A common pattern in young nonprofits is that the founder knows the donors, the bank login, the program details and the history, and the board defers on everything. It usually comes from good intentions, but it creates real risk: no one else can step in during an illness, and no one is positioned to question a decision. A few habits help:

  • Put bank accounts, the domain name, and online accounts in the organization's name, with at least two people holding access.
  • Have the treasurer, not the executive director, present the financial report.
  • Hold a short closed session of independent directors at least once a year to review the executive director's performance.
  • Write down key procedures so they survive a change in leadership.

Frequently asked questions

Can a board member be held personally liable?

Liability rules come from state law, so check your state's nonprofit statute for any protection it gives volunteer directors. Acting in good faith, staying informed and documenting decisions is the best protection in any state; self-dealing is not protected. Some federal taxes reach individuals directly, such as the 10% excise tax on managers who knowingly approve an excess benefit transaction. Directors and officers (D&O) insurance is another layer worth pricing.

Can family members serve on the same board?

Federal law does not prohibit it, but Form 990, Part VI, line 2 asks about family relationships among officers, directors and key employees, and family relationships can affect independence. A board made up mostly of one family is weak on oversight and may draw extra questions on your exemption application.

Do directors have to be paid or unpaid?

Check your state's law and your bylaws. Federal tax law does not forbid paying directors, but any pay must be reasonable, should be approved by directors without a conflict, and is reported on Form 990, Part VII. Paying a director for services beyond board work can also cost them their "independent" status on Part VI.

How often should the board meet?

Your bylaws set the minimum. Many small boards meet quarterly, with an annual meeting to elect officers. Whatever the schedule, keep written minutes; Part VI, line 8a asks whether you did. Our guide to the first board meeting covers the opening agenda.
