Missouri nonprofit board requirements

What the Missouri Nonprofit Corporation Act requires of a Missouri nonprofit board: how many directors you need, how long they serve, what counts as a quorum, and what has to be filed. Every fact below is cited to the statute.

The short answer

A Missouri nonprofit needs at least 3 directors.

Section 355.321.2 says a board of directors "must consist of three or more persons," with the number set in or fixed in accordance with the articles or bylaws. Section 355.321.3 lets the number go up or down over time but never below three. All directors must be natural persons. This is a single uniform floor: Missouri does not set a different minimum for public benefit corporations, mutual benefit corporations, or corporations without members.

What the statute requires

Governing statute
Missouri Nonprofit Corporation Act, Mo. Rev. Stat. sections 355.001 to 355.881
Minimum directors
3. Section 355.321.2 says a board of directors "must consist of three or more persons," with the number set in or fixed in accordance with the articles or bylaws. Section 355.321.3 lets the number go up or down over time but never below three. All directors must be natural persons. This is a single uniform floor: Missouri does not set a different minimum for public benefit corporations, mutual benefit corporations, or corporations without members.
Term length
The articles or bylaws set the terms, and except for designated or appointed directors, a term may not exceed six years. If no term is specified, each director's term is one year, and directors may be elected for successive terms (section 355.331.1). A director keeps serving after a term expires until a successor is elected, designated, or appointed and qualifies (section 355.331.4).
Term limits
Not specified by statute.
Quorum
Unless the chapter, the articles, or the bylaws say otherwise, a quorum is a majority of the directors in office immediately before the meeting begins. The articles or bylaws may change that number, but they can never set a quorum below the greater of one-third of the directors in office or two directors (section 355.401.1). On a three-member board that floor works out to two. If a quorum is present, a majority of the directors present is the act of the board.
Annual meeting
A corporation with members must hold a membership meeting annually at a time stated in or fixed in accordance with the bylaws, and at that meeting the president and chief financial officer report on the corporation's activities and financial condition (section 355.231). Failing to hold it does not affect the validity of any corporate action. A corporation with no members has no statutory annual meeting, and the chapter sets no minimum number of board meetings for anyone.
Conflict of interest
Section 355.416 defines a conflict of interest transaction as one in which a director has a material interest. For a public benefit corporation, such a transaction involving a noncompensated director is not voidable and is not a basis for liability if it was not unfair to the corporation when entered into, or if the board or a committee approved it in advance after the material facts and the director's interest were disclosed and the approving directors reasonably believed in good faith that it was not unfair. Approval by the Attorney General, or by a circuit court with the Attorney General joined, also works. Approval takes a majority of the directors with no direct or indirect interest, and section 355.416.4 says a transaction may not be approved under this section by a single director.
Removing a director
Members may remove a director they elected without cause, but only if the votes cast to remove would have been enough to elect that director, and only at a meeting whose notice says removal is a purpose (section 355.346). A director elected by the board may be removed without cause by a two-thirds vote of the directors then in office. If the articles or bylaws said so at the start of the term, the board may also remove a director by majority vote for missing a set number of meetings. An appointed director may be removed by whoever appointed them (section 355.351). A circuit court may remove a director for fraudulent or dishonest conduct or gross abuse of authority, on a petition from the corporation, members holding 10 percent of the voting power, or the Attorney General (section 355.356).
Recurring state filing
A corporate registration report goes to the Secretary of State listing the registered agent and office, the principal office, and the names and addresses of the directors and principal officers. The first one is due by August 31 of the year following incorporation, and by August 31 each year after that (section 355.856). A late report is only accepted with an added $15 fee, and not filing within 90 days of the due date is grounds for administrative dissolution (section 355.706). Section 355.857 lets a corporation file biennially instead. Most Missouri charities do not register with the Attorney General, because organizations exempt under section 501(c)(3), 501(c)(7), or 501(c)(8) are exempt from charitable registration (section 407.456.2).

What's particular to Missouri

Missouri is one of the few states that caps how long a single board term can run. Section 355.331.1 says that except for designated or appointed directors, "the terms of directors may not exceed six years." Read it carefully, because it limits the length of one term, not the number of terms. A director can be re-elected to six-year terms indefinitely, since the same sentence block says directors may be elected for successive terms.

Missouri expressly allows loans to board members, which many state nonprofit acts flatly prohibit. Section 355.421 says a corporation exempt under section 501(c) may lend money to or guarantee the obligation of a director or officer, so long as the loan does not exceed the lesser of 25 percent of the corporation's total assets or $250,000. Federal rules on self-dealing and excess benefit transactions still apply on their own terms, so state permission is not the end of the analysis.

The recurring filing has an unusual opt-in. Section 355.857 lets a nonprofit switch from the annual registration report to a biennial one, but the year it may file in is locked to the parity of the year it was incorporated: a corporation formed in an even-numbered year may only file biennially in even-numbered years, and the same for odd. Once you choose biennial you are committed for the full 24 months.

Most Missouri charities never register with the Attorney General at all. Section 407.456.2(6) exempts any organization holding a federal exemption under section 501(c)(3), 501(c)(7), or 501(c)(8), provided no part of net earnings benefits a private party. That is a much broader exemption than the narrow religious or small-revenue carve-outs most registration states use, and it means the Secretary of State report is usually the only recurring state filing a Missouri nonprofit has.

This is a summary, not legal advice.

We cite the statute so you can read it yourself, and we last checked these on September 2, 2026. Statutes change, courts interpret them, and your own bylaws may impose stricter rules than the state does. Before you rely on any of this for a decision that matters, have a lawyer licensed in Missouri review it.

Knowing the rule is the easy part.

Staying compliant means knowing whose term ends in March, whether you'll still have quorum after it does, and who hasn't signed this year's conflict of interest form. Board Manager tracks all three and tells you before they become a problem.
