Understanding California Nonprofit Integrity Act & Nonprofit Audit Requirements

You run a nonprofit organization because you care about making a difference. But the reality is good intentions aren’t enough to maintain public trust or secure funding. In California, if your organization brings in $2 million or more annually, you’re operating under some of the strictest financial oversight requirements in the nation.

The California Nonprofit Integrity Act changed everything in 2005. It transformed how nonprofits handle audits, established mandatory audit committees, and created transparency requirements that can make or break your organization’s reputation. Miss these requirements? You’re looking at legal penalties, damaged credibility, and potentially losing your tax-exempt status.

But here’s what many nonprofit leaders don’t realize: these requirements aren’t just bureaucratic hurdles. They’re your organization’s pathway to building unshakeable trust with donors, securing major grants, and establishing the kind of financial credibility that attracts serious funding. When done right, nonprofit audit requirements become your competitive advantage.

This guide will walk you through everything you need to know about the California Nonprofit Integrity Act, from mandatory audit thresholds to establishing compliant audit committees. Whether you’re approaching the $2 million mark or already there, understanding these requirements is about positioning your nonprofit for sustainable growth.

Background & Purpose Of The California Nonprofit Integrity Act

Remember Enron? WorldCom? Those corporate scandals didn’t just rock the business world, they sent shockwaves through the nonprofit sector too. When public trust in organizational transparency hit rock bottom in the early 2000s, California responded with legislation that would forever change how nonprofits operate.

Governor Arnold Schwarzenegger signed the California Nonprofit Integrity Act into law on September 29, 2004, with an effective date of January 1, 2005. This wasn’t just another piece of regulatory paperwork. The Act was intended in part to be an analog to the federal Sarbanes-Oxley Act of 2002, which addresses the financial accountability of for-profit corporations.

The Act focuses on three critical areas:

• Financial audits for larger nonprofits – Organizations with gross revenues of $2 million or more must undergo independent audits
• Governance reforms – Mandatory audit committees with specific composition requirements
• Public accountability – Enhanced disclosure and transparency obligations

The driving force behind this legislation? Simple: public trust. The Act focuses on the financial practices and governance of nonprofit organizations in an effort to ensure that adequate accountability exists. When donors write checks or foundations award grants, they need confidence that their money is being managed responsibly.

Why this matters for your nonprofit:

The Act applies to charitable corporations, unincorporated associations, and charitable trusts required to register with the California Attorney General’s Registry of Charitable Trusts. If you’re raising funds in California or incorporated here, you’re likely subject to these requirements.

But here’s the thing—compliance isn’t just about avoiding penalties. Organizations that embrace these requirements often find they gain a significant competitive advantage when applying for grants or courting major donors. Audited financial statements and strong governance structures signal professionalism and accountability that funders actively seek.

The California Registry of Charitable Trusts oversees compliance, and they’re not just checking boxes. They’re making sure that charitable assets are protected and that organizations operate with the transparency the public deserves. This oversight creates a framework where responsible nonprofits thrive while poorly managed organizations are held accountable.

Nonprofit Audit Requirements Under The California Nonprofit Integrity Act

Let’s get right to it: if your nonprofit’s gross revenues hit $2 million or more in any fiscal year, you need an independent audit. No exceptions, no excuses, no “we’ll get to it next year.”

Here’s exactly what triggers the audit requirement:

Only a charitable organization with annual gross revenues of $2 million or more is subject to the audit requirement. But there’s an important exception: Grant or contract income from the government is not included in gross revenue so long as the governmental entity requires an accounting of those funds.

This means if you receive a $500,000 government grant that requires separate accounting, that money doesn’t count toward your $2 million threshold. Smart exemption, the state recognizes that government grants already come with their own accountability measures.

What exactly is required?

Your annual financial statements must be:

• Audited by an independent certified public accountant (CPA)
• Prepared using Generally Accepted Accounting Principles (GAAP)
• Conducted following Generally Accepted Auditing Standards (GAAS)

Independence standards are crucial. If your CPA firm also provides non-audit services like bookkeeping or consulting, they must follow independence standards outlined in the Yellow Book issued by the U.S. Comptroller General. This prevents conflicts of interest that could compromise audit objectivity.

Timeline requirements you can’t ignore:

The audited financial statements must be made available for inspection by the Attorney General and the public no later than nine months after the close of the fiscal year covered by the financial statement. Miss this deadline? You’re in violation.

Organizations covered include:

• Charitable corporations (regardless of 501(c)(3) status)
• Unincorporated associations holding charitable assets
• Charitable trusts
• Out-of-state organizations operating in California

Common misconceptions to avoid:

Many nonprofit leaders think they can get around the requirement by restructuring their revenue or delaying income recognition. Don’t try it. The office of the Attorney General has seen every creative financial trick there is, and they take attempts to avoid following the rules very seriously.

Technology considerations:

Modern nonprofits using platforms like QuickBooks, Sage, or NetSuite for financial management often find the audit process smoother. These systems provide the detailed transaction histories and internal controls that auditors need to complete their work efficiently.

Consequences of non-compliance:

Beyond legal penalties, non-compliance damages your organization’s reputation irreparably. Donors research nonprofits before giving, and missing audit requirements signals poor management. Grant-making foundations routinely exclude non-compliant organizations from consideration.

The bottom line: If you’re approaching the $2 million threshold, start planning for audit compliance now. Don’t wait until you’re over the line. Preparation takes time, and rushing to comply after the fact often results in costly mistakes or delays that can harm your operations.

Working with experienced CPA firms that understand nonprofit complexities ensures your audit process runs smoothly and positions your organization for continued growth and donor confidence.

The Role And Requirements Of The Audit Committee

Creating an audit committee isn’t just about checking a compliance box. It’s about building a governance structure that protects your organization and enhances its credibility. If your nonprofit meets the $2 million revenue threshold, an audit committee isn’t optional.

Who must establish an audit committee?

Charitable corporations that meet the revenue threshold and must register and file reports with the California Attorney General.

Composition rules that matter:

The law is specific about who can and cannot serve on your audit committee:

Prohibited members:

• Staff members (including volunteers in staff roles)
• President or chief executive officer
• Treasurer or chief financial officer
• Anyone with a material financial interest in entities doing business with your organization

Special finance committee considerations: 

• Members of the finance committee may serve on the audit committee but must constitute less than 50% of its members.
• The audit committee chair cannot be a member of the finance committee.

Unique flexibility: The audit committee may include non-board members and can even consist of a single person to bring in needed financial expertise.

Core responsibilities your audit committee must handle:

1. Auditor selection and management

• Recommending hiring and firing of independent CPAs to the board
• Negotiating auditor compensation on behalf of the governing board
• Ensuring auditor independence and qualifications

2. Audit oversight

• Consult with the auditor to satisfy committee members that the financial affairs of the nonprofit organization are in order
• Review audit findings and determine whether to accept audit results
• Address management letter recommendations and internal control deficiencies

3. Non-audit services approval 

• Approve non-audit services provided by the CPA firm
• Ensure such services conform to standards in the Yellow Book issued by the U.S. Comptroller General

Best practices for effective audit committees:

• Make sure at least one member is a financial expert, ideally a CPA unaffiliated with the audit firm
• Hold regular meetings (three to six times per year) for ongoing oversight
• Provide committee members with comprehensive information well in advance of meetings
• Maintain open communication with management and external auditors
• Preserve committee independence while allowing management to provide information as needed

Independence preservation:

Your audit committee’s independence allows objective assessment of financial procedures, staff performance, and auditor effectiveness. While the CFO and executive director can’t serve on the committee, they should attend meetings when requested to provide information and answer questions.

Common implementation challenges:

Many nonprofits struggle to find qualified volunteers willing to serve on audit committees. Consider reaching out to:

• Retired CPAs or financial professionals
• Corporate volunteers through community partnership programs
• Board members from other nonprofits with relevant experience
• University accounting faculty who support community organizations

Working with your CPA firm:

Your audit committee should establish clear expectations with your chosen CPA firm about communication, timelines, and deliverables. Experienced firms can guide your committee through best practices and help establish efficient processes.

The audit committee serves as your organization’s financial watchdog, providing oversight that protects against errors, fraud, and poor financial management while ensuring compliance with legal requirements.

Public Disclosure & Transparency Obligations

Once your nonprofit completes its required audit, those financial statements become public documents that anyone can access and review.

Mandatory disclosure requirements:

Audited statements must be made available to the public for a period of three years, both (1) at the charitable organization’s principal and any regional or district office during regular business hours, and (2) by mailing a copy to any person who so requests in person or in writing.

You have options for compliance:

• Physical copies available at your offices during business hours
• Mailing copies to requesters (you can charge reasonable copying and mailing fees)
• Posting the audited statements on the charitable organization’s website

Why transparency builds trust:

When potential donors can easily access your audited financial statements, it demonstrates confidence in your financial management. Organizations that hide their financials or make them difficult to obtain raise immediate red flags with sophisticated donors and grant-makers.

Strategic advantages of proactive disclosure:

Smart nonprofits proactively publish audited statements on their websites. This approach:

• Demonstrates transparency and builds donor confidence
• Reduces administrative burden of responding to individual requests
• Shows prospective funders that you have nothing to hide
• Differentiates your organization from less transparent competitors

Best practices for disclosure:

• Website posting: Create a dedicated “Financial Information” or “Transparency” section on your website where stakeholders can easily find current and past audited statements.
• Format considerations: Post statements in searchable PDF format, making it easy for reviewers to find specific information they need.
• Additional documentation: Consider posting your IRS Form 990 alongside audited statements for complete transparency.
• Communication strategy: Don’t just post documents and hope people find them. Announce availability in newsletters, annual reports, and donor communications.

Supporting fundraising efforts:

Transparent financial reporting directly supports fundraising in several ways:

• Grant applications often require audited statements and having them readily available streamlines the application process
• Major donors frequently request financial information before making significant gifts
• Foundation program officers appreciate organizations that make due diligence easy
• Transparent reporting demonstrates the kind of accountability that attracts serious philanthropic investment

Managing potential concerns:

Some nonprofit leaders worry that public financial disclosure might reveal competitive information or donor details. Properly prepared audited statements protect sensitive information while providing the transparency required by law and expected by stakeholders.

Remember: The Act adopts the same rules for public disclosure already applicable to IRS Form 990. If you’re already comfortable with Form 990 transparency requirements, audited statement disclosure follows the same principles.

The organizations that thrive under these transparency requirements are those that view disclosure as an opportunity to showcase their financial responsibility rather than an obligation to fulfill reluctantly.

Practical Steps For Nonprofits To Comply With The California Nonprofit Integrity Act

Compliance doesn’t happen overnight. Smart nonprofit leaders start preparing well before they hit the $2 million threshold, because scrambling to meet requirements after the fact often results in costly mistakes and delays.

Step 1: Assess your revenue trajectory

Track your organization’s gross revenue trends carefully. The Attorney General interprets the term “gross revenues” in the NIA to be the same as “total revenue” used by the IRS on line 12 of Form 990 and line 12 column (a) of Form 990-PF.

Don’t forget the government grant exclusion: grants requiring separate accounting to the governmental entity don’t count toward your threshold. Calculate both your total revenue and your revenue subject to the Act to understand where you stand.

Step 2: Prepare for independent audit requirements

Choose your CPA firm strategically:

• Look for firms with extensive nonprofit audit experience
• Verify their independence from any services you currently use
• Ensure they understand California Nonprofit Integrity Act requirements specifically
• Ask for references from similar-sized nonprofits they serve

Organize your financial systems: Modern accounting platforms like QuickBooks, Sage, and NetSuite can streamline audit preparation significantly. These systems provide:

• Detailed transaction histories auditors need
• Internal control documentation and segregation of duties
• Automated reporting that reduces manual errors
• Digital document storage for supporting documentation

Internal controls assessment: Before your first audit, evaluate your organization’s internal controls:

• Who can approve expenditures at different dollar levels?
• How are cash receipts handled and recorded?
• What documentation requirements exist for different transaction types?
• How are conflicts of interest managed and disclosed?

Addressing internal control weaknesses before your audit begins prevents embarrassing findings and demonstrates proactive management.

Step 3: Establish your audit committee

Recruitment strategy: Finding qualified audit committee members requires intentional outreach:

• Retired professionals: Former CPAs, CFOs, and financial managers often welcome meaningful volunteer opportunities
• Corporate partnerships: Many companies encourage employees to serve on nonprofit boards and committees
• Professional networks: CPA societies and financial professional associations often maintain volunteer databases
• University connections: Business school faculty frequently support community organizations

Committee charter development: Create a written charter defining:

• Committee composition and member qualifications
• Meeting frequency and procedures
• Specific responsibilities and authority
• Relationship to the full board
• Auditor selection and oversight processes

Step 4: Technology implementation

Financial management systems: Solid financial systems aren’t bonuses; they’re required for audit compliance. Consider upgrading to:

• Cloud-based platforms that provide real-time access for committee members and auditors
• Integrated systems that connect financial data with program tracking
• Automated controls that prevent common errors and enforce approval workflows

Document management: Implement systems for storing and organizing:

• Board resolutions and meeting minutes
• Financial policies and procedures
• Grant agreements and compliance documentation
• Vendor contracts and supporting documentation

Step 5: Annual planning and timeline management

Create audit calendar: Successful compliance requires planning audit activities throughout the year:

• Quarterly internal reviews to identify issues early
• Mid-year audit committee meetings to review interim financials
• Pre-audit preparation starting 3-4 months before fiscal year-end
• Post-audit implementation of auditor recommendations

Board governance integration: Make sure your board understands their oversight responsibilities:

• Regular financial statement review at board meetings
• Annual board education on fiduciary responsibilities
• Clear policies for addressing audit findings and recommendations

Professional partnership approach:

Working with experienced professionals who understand nonprofit complexities guarantees your compliance efforts succeed. Look for CPA firms that:

• Provide year-round support, not just audit services
• Help implement systems that support ongoing compliance
• Offer training for board and staff on best practices
• Stay current on evolving regulatory requirements

Avoiding common mistakes:

Don’t wait until December to start planning your audit if you have a December fiscal year-end. Quality audits require preparation, and rushing the process often results in higher costs and compliance problems.

Never view audit preparation as a once-yearly event. Organizations with strong ongoing financial management find audits straightforward and cost-effective, while those that scramble annually face unnecessary stress and expense.

The nonprofits that handle these requirements most successfully treat compliance as an integral Part Of Their Operational Excellence, Not An Add-On Obligation.
