California Nonprofit Law: Board of Directors Requirements

California law requires every nonprofit public benefit corporation to have a board of directors of at least three people, and the Corporations Code sets specific requirements for how those directors are chosen, how they must act, and what happens when they don’t. The board runs the organization: it manages activities, exercises corporate powers, approves major transactions, and answers to the Attorney General for how charitable assets are handled. Treating a seat as honorary doesn’t reduce the legal exposure that comes with it.

What follows covers the board rules for California public benefit corporations, the type most charitable nonprofits use. Mutual benefit corporations (trade groups, HOAs, social clubs) and religious corporations operate under related but distinct provisions of the Corporations Code and face lighter Attorney General oversight.

Minimum Board Size and Structure

A California public benefit corporation must have at least three directors.¹ The organization’s bylaws set the exact number of seats above that floor, the qualifications for serving, and the process for electing and removing directors. Bylaws function as the internal operating rules of the corporation and must be consistent with state law.

A majority of authorized directors constitutes a quorum for board business. Bylaws can adjust that number, but not below one-fifth of authorized directors or two, whichever is greater. Boards are expected to meet regularly, notice must be given to all directors before meetings, and minutes must be recorded and kept as part of the corporation’s official records. Those minutes are the evidence of what the board authorized and are routinely pulled during audits and regulatory reviews.¹

Fiduciary Duties Directors Owe the Organization

The Corporations Code spells out what directors owe the nonprofit with unusual specificity. These are enforceable legal standards, and the Attorney General can sue directors who ignore them.

Duty of Care

Each director must act in good faith, in a manner the director believes is in the organization’s best interests, and with the care, including reasonable inquiry, that an ordinarily prudent person in a similar position would use under similar circumstances.² “Reasonable inquiry” is where most boards fall short. Attending meetings isn’t enough. Directors need to read the financial reports, ask questions when numbers don’t look right, and understand what they’re voting on before they vote.

Duty of Loyalty and Self-Dealing

Directors must put the corporation’s interests ahead of their own. Corporations Code Section 5233 governs self-dealing transactions—any deal in which a director has a material financial interest. A self-dealing transaction is presumed invalid unless the board follows a specific procedure.³

To protect the transaction, all of the following typically must be true: the corporation entered the transaction for its own benefit; the deal 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 better alternative was reasonably available.³ The interested director cannot vote. Skip any step and the Attorney General can seek to unwind the transaction and hold the director personally liable.

Investment Standards

When directors manage the corporation’s investment assets, they must avoid speculation, focus on the long-term safety of the corporation’s capital, and consider the probable income from investments. These standards apply to assets held for investment, not to property used directly in the nonprofit’s charitable programs.⁴

Excess Benefit Transactions and Compensation

Federal law adds another layer over the state loyalty rules. The IRS imposes excise taxes on “excess benefit transactions”—deals where a disqualified person (typically an officer, director, or someone with substantial influence) receives more than fair market value from the organization. The insider owes a 25% excise tax on the excess benefit, rising to an additional 200% if the transaction isn’t corrected within the taxable period.⁵

Board members who knowingly approve the transaction face a 10% excise tax on the excess benefit, capped at $20,000 per transaction, when their participation was willful and not due to reasonable cause.⁵ For executive compensation and any deal with an insider, the board should gather comparability data, have disinterested directors approve the terms, and document its reasoning in the minutes.

Required Written Policies

Some policies are legally required; others are asked about directly on IRS Form 990 and are effectively expected of any serious board.

Conflict of Interest Policy

California’s self-dealing statute sets the legal baseline, but the IRS expects nonprofits to adopt a written conflict of interest policy on top of it. Form 990 asks whether the organization has one, how conflicts are managed, and how the organization identifies conflicting interests among directors and officers. A workable policy requires annual disclosure of potential conflicts and bars interested directors from voting on matters where a conflict exists.

Whistleblower Protection

Under provisions of the Sarbanes-Oxley Act that apply to all entities including nonprofits, it is a federal crime to retaliate against an employee who reports suspected illegal activity. Retaliation includes firing, demotion, suspension, harassment, and other forms of discrimination. An employee doesn’t need to prove misconduct actually occurred; a reasonable belief that fraud or illegal activity exists is enough to trigger protection. Boards should adopt a formal complaint-handling process and a written anti-retaliation policy.

Document Retention and Destruction

Sarbanes-Oxley also makes it a federal crime to alter, destroy, or falsify documents to obstruct an official proceeding. If an investigation is underway or even suspected, the organization must immediately halt any routine document purging. A written document retention policy should cover financial records, contracts, employment files, fundraising records, and electronic communications, with retention periods and destruction procedures for each category.

Filings the Board Is Responsible For

The board is the body that answers when filings are missed. Three state agencies and the IRS all have recurring requirements.

The Secretary of State requires the Statement of Information (Form SI-100) every two years after incorporation. Missing it can lead to entity suspension.⁶

The Franchise Tax Board requires an annual return. Organizations with gross receipts over $50,000 file Form 199; those normally at or below $50,000 can file the FTB 199N e-Postcard. Private foundations file Form 199 regardless of size. Form 199 is due by the 15th day of the fifth month after the accounting period closes.⁷⁸

The Attorney General’s Registry of Charities and Fundraisers requires initial registration within 30 days of first receiving charitable assets, then an annual Form RRF-1 with financial statements and governance information.⁹

Federally, the IRS uses a tiered Form 990 system:

Gross receipts normally $50,000 or less: Form 990-N (e-Postcard).
Gross receipts under $200,000 and total assets under $500,000: Form 990-EZ or the full Form 990.
Gross receipts of $200,000 or more, or total assets of $500,000 or more: full Form 990.

Missing three consecutive years of these filings costs the organization its federal tax-exempt status automatically, effective on the third year’s filing due date.¹⁰ The FTB revokes state exemption when the IRS revokes the federal one.⁸

Audit Threshold

California’s Nonprofit Integrity Act requires an independent audit of annual financial statements for any charitable organization that accrues $2 million or more in gross revenue in a fiscal year. The rule applies to charitable corporations, unincorporated associations, and trustees registered with the Attorney General.¹¹ Below that threshold, an audit isn’t required, but the Attorney General can request financial information from any registered charity at any time.

Personal Liability and How Directors Are Protected

Board service carries genuine exposure, and both California and federal law create meaningful protections for directors who act responsibly.

Indemnification

Corporations Code Section 5238 allows nonprofits to indemnify directors and officers for expenses and liabilities incurred in their official capacity, provided the director acted in good faith, believed the conduct was in the organization’s best interests, and used the care an ordinarily prudent person would use.¹² Indemnification isn’t available when a director is found liable to the corporation for breaching duties. Many organizations write mandatory indemnification into the bylaws so directors aren’t left depending on a future board’s discretion.

Federal Volunteer Protection Act

The federal Volunteer Protection Act limits personal liability for volunteers of nonprofit organizations, including unpaid board members, for harm caused within the scope of their responsibilities. The protection falls away for willful or criminal misconduct, gross negligence, reckless behavior, or conscious indifference to the rights or safety of the person harmed. It also doesn’t cover harm caused while operating a motor vehicle or other vehicle requiring a license or insurance.¹³

Directors and Officers Insurance

D&O policies typically cover defense costs and settlements arising from claims against directors for decisions made in their official capacity. Common exclusions carve out 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. Review those exclusions with your broker before assuming you’re covered.

The Payroll Tax Trap

The exposure that surprises board members most often is unpaid payroll taxes. Under 26 U.S.C. Section 6672, any person responsible for collecting and paying over employment taxes who willfully fails to do so can be personally liable for the full unpaid amount. There is an exception for unpaid, volunteer board members, but it applies only if the director serves in a purely honorary capacity, doesn’t participate in day-to-day or financial operations, and has no actual knowledge of the failure to pay.¹⁴ Miss any one condition and the exception is gone. Directors who sign checks, approve budgets, or have signing authority on financial accounts are the most exposed.

Removing and Replacing Directors

Removal procedures are set by Corporations Code Section 5222 and depend on whether the nonprofit has members.¹⁵

No members: a director can be removed by a majority vote of the directors then in office.
Fewer than 50 members: removal generally requires approval under the organization’s member-approval procedures.
50 or more members: removal must be approved by the members through a formal vote.

A director generally cannot be removed before the term expires except through the statutory procedures. If a director was designated by a specific person or entity rather than elected, that designator typically has the right to remove the director without cause unless the bylaws say otherwise.¹⁵ Bylaws should specify how vacancies are filled—usually by the remaining directors or a nominating committee. Fill vacancies promptly. A board that drops below quorum can’t conduct business, and that failure cascades into missed filings, delayed decisions, and the compliance problems that follow.
