Every California nonprofit public benefit corporation must have a board of at least three directors, and each director is bound by specific fiduciary duties written into the Corporations Code. The California nonprofit board of directors requirements go beyond headcount: the board sets its own size through bylaws, has to meet with proper notice and recorded minutes, must approve certain transactions under strict procedures, and must adopt policies that regulators expect to see. Directors who treat the seat as honorary can end up personally liable when something goes wrong.
Most of what follows applies to public benefit corporations, the category that covers the great majority of California charities. Mutual benefit corporations (trade associations, HOAs, social clubs) and religious corporations operate under their own rules in the Corporations Code and face lighter Attorney General oversight.
Minimum Board Size and Composition
A California public benefit corporation needs a board of directors that manages the corporation’s activities and exercises its corporate powers.1Justia Law. California Corporations Code 5210-5215 The floor is three directors. The exact number of seats, who is eligible to hold them, how long they serve, and how they are chosen or removed all live in the organization’s bylaws.
Bylaws are the internal operating rules of the corporation and must be consistent with state law. A workable set addresses term lengths, officer roles, committee structure, meeting frequency, and voting procedures. Getting the bylaws right at the start saves the board from having to improvise during a dispute.
Meetings, Notice, and Quorum
Boards are expected to meet regularly, with proper notice to every director before each meeting. A majority of authorized directors is the default quorum for conducting business. Bylaws can set a different number, but not less than one-fifth of the authorized directors or two directors, whichever is greater.1Justia Law. California Corporations Code 5210-5215
Minutes have to be kept as part of the corporation’s official records. They are the evidence of what the board actually authorized, and auditors, the Attorney General, and successor boards all rely on them.1Justia Law. California Corporations Code 5210-5215 Thin or missing minutes are a recurring problem in enforcement matters.
Fiduciary Duties Every Director Owes
The Corporations Code spells out director duties with unusual specificity. These are enforceable standards, not aspirations, and the Attorney General can sue to enforce them.
Duty of Care
Each director must act in good faith, in a manner the director believes is in the corporation’s best interests, and with the care — including reasonable inquiry — that an ordinarily prudent person in a similar position would use under similar circumstances.2California Legislative Information. California Corporations Code 5231 “Reasonable inquiry” is the part most boards underestimate. Attendance is not enough. Directors are expected to read the financials, ask questions when numbers look off, and understand the matters they vote on.
Duty of Loyalty and Self-Dealing
Directors must put the organization’s interests ahead of their own. Section 5233 presumes a transaction in which a director has a material financial interest to be a self-dealing transaction unless it fits a statutory safe harbor.3California Legislative Information. California Corporations Code 5233
To protect a self-dealing transaction from being unwound, the board generally needs all of the following: the corporation entered into the transaction for its own benefit; the transaction was fair and reasonable at the time; a majority of disinterested directors approved it in good faith with knowledge of the material facts; and the board determined after reasonable investigation that no more advantageous arrangement could be obtained with reasonable effort.3California Legislative Information. California Corporations Code 5233 The interested director cannot vote. Getting the process wrong exposes that director to personal liability and lets the Attorney General seek to void the deal.
Federal tax law layers on another penalty for insider deals. If a board approves unreasonable compensation or a below-market transfer to a “disqualified person” (officers, directors, or anyone with substantial influence), the insider owes a 25% excise tax on the excess benefit, rising to 200% if the transaction is not corrected within the taxable period. Board members who knowingly approve the transaction without reasonable cause face their own 10% excise tax on the excess benefit, capped at $20,000 per transaction.4Internal Revenue Service. Intermediate Sanctions – Excise Taxes The practical defense: document the comparability data behind executive compensation and have disinterested directors sign off.
Investment Standards
When managing investment assets, directors must avoid speculation, focus on the long-term safety of capital, and consider probable income. The standard applies to assets held for investment, not to property the nonprofit uses directly in its programs.5California Legislative Information. California Corporations Code 5240
Policies the Board Is Expected to Adopt
Beyond the statute, some policies are legally required and others are expected by regulators and asked about on IRS Form 990.
Conflict of Interest Policy
Section 5233 is the legal framework, but the IRS expects a written conflict of interest policy on top of it. Form 990 asks whether the organization has one, how conflicts are identified, and how they are managed. A workable policy requires directors and officers to disclose potential conflicts and bars an interested director from voting on any matter where the conflict exists. The board should revisit the policy periodically.
Whistleblower Protection
Two provisions of the Sarbanes-Oxley Act apply to all organizations, including nonprofits. It is a federal crime to retaliate against an employee who reports suspected illegal activity. Retaliation includes firing, demotion, suspension, harassment, or any other adverse action. The employee does not have to prove misconduct actually occurred; a reasonable belief that fraud or illegal activity exists is enough. The board should adopt a written complaint-handling process and a no-retaliation rule.
Document Retention and Destruction
Also under Sarbanes-Oxley, it is a federal crime to alter, destroy, or falsify documents to obstruct an official proceeding. If an investigation is underway or even suspected, routine purging must stop. Every nonprofit should maintain a written retention policy covering financial records, contracts, employment files, fundraising records, and electronic communications, specifying retention periods and destruction procedures for the ordinary course of business.
When the Board Must Order an Audit
Under California’s Nonprofit Integrity Act, any charitable organization that accrues $2 million or more in gross revenue in a fiscal year must have its annual financial statements audited by an independent CPA. The requirement applies to charitable corporations, unincorporated associations, and trustees registered with the Attorney General.6State of California – Department of Justice – Office of the Attorney General. Audit Requirements Under the Nonprofit Integrity Act Below that threshold, the audit is not mandatory, but the Attorney General can still request financial information from any registered charity.
Removing Directors and Filling Vacancies
Section 5222 controls director removal, and the procedure depends on whether the nonprofit has members. For a nonprofit with no members, a director can be removed by a majority vote of the directors then in office. For a nonprofit with fewer than 50 members, removal generally runs through the member-approval procedures. For those with 50 or more members, removal must be approved by the members through a formal vote.7California Legislative Information. California Corporations Code 5222
A director generally cannot be removed before the term expires except through the statute’s procedures. If a director was designated by a particular person or entity rather than elected, that designator usually has the right to remove the director without cause, unless the bylaws say otherwise.7California Legislative Information. California Corporations Code 5222
Vacancies should be filled through whatever mechanism the bylaws set, often a nominating committee or a vote of the remaining directors. Filling them promptly matters because a board that drops below quorum cannot conduct business, and that failure cascades into missed filings and missed approvals.
Personal Liability and the Protections Against It
Board service carries real exposure, and California and federal law both provide protection for directors who act responsibly.
Indemnification
Corporations Code Section 5238 lets a nonprofit indemnify directors and officers for expenses and liabilities incurred in their official capacity, provided they acted in good faith, believed their conduct was in the corporation’s best interests, and used the care an ordinarily prudent person would use.8California Legislative Information. California Code, Corporations Code CORP 5238 Indemnification is not available when a director is found liable to the corporation for breach of duty. Many organizations write mandatory indemnification into their bylaws so a director does not have to rely on a future board to reimburse them.
Federal Volunteer Protection Act
The federal Volunteer Protection Act limits personal liability for volunteers of nonprofit organizations, including unpaid directors, for harm caused while acting within the scope of their responsibilities. The protection does not apply when conduct involved willful or criminal misconduct, gross negligence, reckless behavior, or conscious indifference to the rights or safety of the person harmed. It also does not cover harm caused while operating a motor vehicle or other vehicle requiring a license or insurance.9Office of the Law Revision Counsel. 42 USC 14503 – Limitation on Liability for Volunteers
D&O Insurance
Many nonprofits buy Directors and Officers liability insurance. Typical policies cover defense costs and settlements for claims against directors arising from decisions made in their official capacity. The exclusions matter: fraud or criminal conduct, personal financial gain, disputes between directors at the same organization, and claims based on conduct the director knew about before the policy was purchased are commonly carved out. Review the exclusions with the broker each year.
Payroll Tax Liability
One trap catches board members who assume volunteer status means no personal exposure. Under 26 U.S.C. 6672, any person responsible for collecting and paying over employment taxes who willfully fails to do so can be personally liable for the full amount of unpaid taxes. There is an exception for unpaid, volunteer directors, but only if they serve in a purely honorary capacity, do not participate in day-to-day or financial operations, and have no actual knowledge of the failure to pay. Miss any one of those conditions and the exception falls away.10Office of the Law Revision Counsel. 26 U.S. Code 6672 – Failure to Collect and Pay Over Tax, or Attempt to Evade or Defeat Tax Directors who sign checks, approve budgets, or have authority over financial accounts are the ones most often reached by this rule.
Taken together, the California requirements for a nonprofit board are structural, procedural, and personal. Three directors is the starting point. What keeps the board — and each individual on it — out of trouble is the written record: bylaws that match the statute, minutes that show the reasoning, a conflict policy that is actually followed, and documentation of the comparability data behind compensation and insider transactions.
