  • Provides assurance of ethical and effective fund utilization.
  • Identifies internal control weaknesses, safeguarding assets.
  • Improves eligibility for grants and funding.
  • Ensures adherence to laws and regulations, preserving public standing.
  • Audit triggers: revenue thresholds, funder requirements, internal policies, or voluntary for credibility.

Single Audit Threshold Change

The Single Audit, required for entities expending significant federal funds, has an upcoming threshold change. Understanding this is vital for compliance.

Overview of Applicable Auditing Standards

CPAs must navigate a complex framework of standards. Click on each standard to learn more. This diagram illustrates their general relationship:

Uniform Guidance (2 CFR Part 200) - For federal award recipients (Single Audit)
Government Auditing Standards (GAGAS / Yellow Book) - For government entities & fund recipients
Generally Accepted Auditing Standards (GAAS) - Foundational for all U.S. audits

Issuing Body: AICPA

Primary Focus: Fundamental audit principles for all entities.

Applicability: All nonprofits in the U.S.

Key Characteristics: Guidance on conducting audits, documentation, opinion types. Ensures high assurance. Categories: General, Field Work, Reporting.

Issuing Body: GAO

Primary Focus: Audits of government entities & recipients of government awards.

Applicability: Nonprofits receiving government funding/grants, or where required by law/regulation.

Key Characteristics: Builds on GAAS. Additional independence & reporting requirements. New (2024 revision) risk-based quality management focus (effective Dec 15, 2025).

Issuing Body: OMB

Primary Focus: Federal award management & audit requirements.

Applicability: Nonprofits expending $750K+ (soon $1M+) in federal funds (triggers Single Audit).

Key Characteristics: Rules on cost principles, administrative requirements, audit obligations. Requires GAAS & GAGAS adherence for Single Audits.

Note on Evolving Standards: The regulatory environment is dynamic. CPAs must stay current, especially with GAGAS quality management changes and Single Audit threshold adjustments, adapting firm processes and training accordingly.

Key Accounting Principles for Nonprofits

Nonprofit accounting has unique principles. Click each to explore:

Issuing Body: FASB

Primary Focus: Framework for financial statement preparation for all non-governmental entities.

Auditor Role: Determine if financial statements adhere to GAAP; note non-adherence in audit report.

Primary Focus: Dictates how nonprofits recognize and report contributions. Crucial for distinguishing between contributions with and without donor restrictions.

Revenue Recognition (Contributions): Recognized when donation is made. Timing depends on whether restricted or unrestricted. Conditional grants recognized when conditions are met (e.g., report delivery, program launch).

Applicability: Applies to nonprofits for exchange transactions (grantor expects direct benefit of equal value).

Revenue Recognition (Exchange): Recognized when performance obligations are satisfied (promised goods/services delivered, control transferred).

Requirement: Mandates all NFPs present the relationship between functional expenses (program services, management/general, fundraising) and natural expenses (salaries, rent).

Purpose: Provides a detailed view of how nonprofits allocate resources towards their missions. Requires careful consideration of expense allocation methods.

Illustrative Example of Functional Expense Allocation (Hypothetical):

Mission Alignment: Unique NFP reporting requirements are tied to their mission and accountability. Audits must ensure financial reporting transparently shows how funds achieve the mission, impacting trust and funding.

I. Pre-Engagement and Planning: Laying the Foundation

The initial phases of a nonprofit audit are crucial for establishing a solid framework. This section covers client acceptance, crafting the engagement letter, understanding the nonprofit's unique context, conducting a comprehensive risk assessment, determining materiality, and developing a tailored audit plan. Effective planning here ensures an efficient and successful audit.

Client Acceptance and Continuance

Formal acceptance (via engagement letter) is the first step. Procedures ensure association with clients of integrity and engagements within firm competence.

  • Assessment: Inquiries of management, financial statement scrutiny, online research, background checks (CEO, CFO).
  • Initial Audits: Critical to communicate with predecessor auditors *before* acceptance (management integrity, disagreements, reasons for change).
  • Post-Acceptance: Inspect predecessor's workpapers, understand related-party transactions.
  • Leading Practice: Rigorous background checks and integrity analysis, especially for public-facing nonprofits. Document all procedures.
  • CPA's Dual Imperative: Ensure firm competence AND assess client integrity to protect firm reputation.

Crafting the Engagement Letter

The foundational document defining scope, responsibilities, and execution. Key for transparency and expectation management.

Key Elements:

  • Parties, audit objective & scope, period under review.
  • Auditor responsibilities (GAAS, independence, opinion, fraud detection limitations).
  • Management responsibilities (documentation, current/accurate records, fieldwork prep, "prep packet").
  • Applicable standards, timeline, communication, fees, confidentiality, termination.

Best Practices:

  • Use plain language, be explicit about exclusions.
  • Tailor to client (industry specifics, special timelines). Review/update annually.
  • Strategic Tool for CPAs: Clearly outlining client responsibilities can reduce audit time/fees and foster collaboration.

Understanding the Nonprofit's Mission, Operations, and Funding

  • Mission Focus: Materiality measures should revolve around the mission; ability to provide services is key for donors.
  • Funding Model: Understand reliance on donations/grants (often with restrictions). Assess diversity vs. single-source reliance for financial risk.
  • Expense Management: Comprehend how expenses are managed with limited resources (operational efficiency, sustainability).
  • Operational Objectives: Familiarity with programs and their relation to financial performance is vital (for performance audits, functional expense allocation).

Comprehensive Risk Assessment

Mandated by standards to assess general business, industry, and company-specific risks. Forms basis for audit procedures.

Key Risk Areas for Nonprofits (Click to expand):

Clarity of board roles, conflicts of interest, outdated bylaws/policies.
Inadequate reserves, undiversified funding, weak internal controls, budget variances.
Insufficient staff/volunteers, lack of succession plans, workplace safety issues.
Non-adherence to regulations, tax-exempt status issues, improper record-keeping, incorrect cost allocation.
Economic/funding trends, political/regulatory changes, crisis preparedness (reputation, cybersecurity).

Risk Management Process:

  • Evaluate likelihood & impact (Low, Medium, High) for prioritization.
  • Strategies: Avoid, retain, share/transfer (outsourcing, insurance).
  • Develop action plan with resources and funding. Revisit annually.
  • Mission-Centric Risk for CPAs: Integrate mission impact. Reputational risk or failure to meet donor expectations can be critical. Assessment should cover threats to mission viability and public trust.

Determining Materiality in a Nonprofit Context

Materiality: Threshold at which misreported info could influence user decisions. Abstract concept requiring specific metrics.

  • Mission-Centered: For nonprofits, materiality measures should center on the organization's unique mission statement. Ability to provide goods/services is paramount for donors.
  • Professional Judgment: Auditors determine if a control deficiency is a material weakness or significant deficiency based on its impact on financial statement accuracy.
  • Higher-Risk Areas: Material weaknesses often appear in complex areas, high-volume/high-value transaction areas (e.g., incorrect recording of conditional contributions/grants).

Developing a Tailored Audit Plan

Follows risk assessment. Outlines specific procedures to test internal controls and investigate financial statement line item accuracy.

  • Audit partner assigns team members strategically.
  • Planning Meeting (Pre-Fieldwork): Discuss items of audit significance, establish clear timeline. Auditor articulates timeline and required items.
  • "Audit Prep Packet": CPA firm may provide details of requested documentation. Nonprofits should inquire about preferred format (e.g., electronic) to save time/cost.
  • Nonprofit audit oversight group should attend to develop submission timeline and seek guidance.

II. Executing the Audit: Fieldwork and Key Areas of Focus

The execution phase, or fieldwork, is the core of the audit. It involves substantive testing and verification procedures tailored to nonprofits. This section details evaluating internal controls, revenue recognition, grant compliance, functional expense classification, specific audit procedures for key accounts, and ensuring compliance with federal and state regulations.

Evaluating and Testing Internal Controls

Internal controls are policies/procedures to safeguard resources, ensure accurate recording, and maintain efficiency. Crucial for NFP reliance on donations/grants.

Benefits of Strong Controls: Protect assets, ensure funds used as intended, promote transparency, facilitate compliance, streamline operations, reduce errors, aid risk mitigation, smoother audit.

Key Control Types (Click to expand):

Designed to deter errors or irregularities from occurring initially.
Aimed at identifying errors or irregularities that have already occurred.
Implemented to remedy detected errors or irregularities.

CPA's Role: Assess risk landscape, inform development of policies/procedures, ensure staff training.

Key Areas for Testing Internal Controls:

  • Segregation of Duties: No single individual controls all aspects of a financial transaction (authorization, recording, reconciliation).
  • Cash Management: Controls over cash handling (authorization, bank reconciliations, surprise counts).
  • Payroll: Accurate processing, timesheet authorization, employee info verification, tax filings.
  • Program Expenditures: Review processes for financial transactions (approval, risk management), verify invoices/receipts.
  • Donor Management: Proper recording/categorization of revenue (restricted/unrestricted), secure technology.
  • Financial Reporting: Accurate, timely, compliant reports; management/board review.
  • Board Oversight: Critical role in overseeing internal control system effectiveness.

Shift in Emphasis: From error detection to proactive prevention, strengthening overall financial health.

Revenue Recognition and Grant Compliance

Accurate revenue recognition is fundamental for transparent reporting and resource management.

Key Standards:

  • FASB ASC 958: For contributions. Differentiates restricted/unrestricted. Unconditional recognized when awarded (if reasonably assured). Conditional recognized when conditions met.
  • FASB ASC 606: For exchange transactions (grantor expects equal value). Recognized when performance obligations satisfied.

Grant Compliance: Ensuring proper use and reporting of grants (state, federal, private). Non-compliance can lead to penalties, funding loss.

CPA Verification Areas:

  • Accurate documentation of donor restrictions (gift instruments).
  • Proper fund allocation per designated purposes.
  • Compliance with reporting obligations to grantors.
  • Detailed financial records (separate restricted funds, program codes, multi-year grant tracking).

Auditor's Scrutiny: Granular examination is vital. Misclassification or improper recognition can lead to audit findings, jeopardize funding, and erode trust. Involves tracing transactions, analyzing agreements, verifying performance obligations.

Functional Expense Classification and Program Expenditure Tracking

Statement of Functional Expenses (SFE) is standard. FASB ASC 958 mandates presenting relationship between functional (program, supporting) and natural (salaries, rent) expenses.

  • Purpose: Offers insight into how NFP allocates spending to mission. Requires careful allocation/reporting.
  • Reporting: All expenses in one location (statement of activities, notes, or separate statement), disaggregated by natural classification.
  • Major Programs: NFPs have latitude. Factors: objectives, services, constituents, magnitude, budget, compliance.
  • Clarifications: Some costs are supporting (e.g., symphony advertising = M&G). Fundraising activities always fundraising expenses.

Programmatic Accountability: CPA's audit ensures financial statements accurately reflect resource deployment to mission, impacting stakeholder perception of efficiency/effectiveness.

Specific Audit Procedures for Key Accounts

Auditors gather evidence via testing internal controls and substantive procedures. Click account types for typical procedures:

Request bank reconciliations (outstanding checks, deposits in transit), subsequent month's statements. Reconciliation for cash held for others.
Review reconciliations of balances, income, gains/losses, purchases, distributions. Annual summary statements. Donated securities documentation.
List of year-end promises, confirm with donors. Review discount to NPV and allowance for uncollectible. Aging of receivables. GAAP: recognize revenue when pledge made, not when cash received (critical for NFP reporting/audit triggers).
Review listings of year-end AP and accrued expenses (payroll tax, paid leave).
Review fixed asset/depreciation schedule, donated asset documentation. Verify physical existence (deeds, appraisals).
Verify proper authorization (budgets, board minutes). Test transactions for compliance with charter/bylaws, proper functional assignment. Review manual journal entries, unusual activity.

Other procedures: Contact third parties (suppliers, customers) for confirmations. Interview staff/board. Ensure all documentation is compiled and available.

Compliance with Federal and State Regulations

Nonprofits operate in a complex regulatory web. Ensuring compliance is a significant audit component.

Trigger: Expending $750K+ in federal funds/year (increasing to $1M for fiscal periods on/after Oct 1, 2024).

Scope: More rigorous than standard audit; reviews financials AND compliance with federal regulations.

Standards: Adheres to GAAS, GAGAS (Yellow Book), and Uniform Guidance (2 CFR Part 200).

GAGAS Adds: Specific independence rules, reporting on internal control, compliance with laws/regs/contracts. Auditors evaluate corrective action on prior findings, inquire about investigations, develop finding elements (criteria, condition, cause, effect).

Tax-exempt orgs file annual info return (Form 990, 990-EZ, 990-PF).

IRS Tool: Gathers info, educates, promotes compliance. Used by states for oversight.

Audit Triggers: Incomplete/inaccurate info. Governance issues. Disproportionate fundraising expenses, unusual executive compensation, substantial UBI without tax payment.

CPA Role: Ensure accurate completion/filing to mitigate IRS examination risk.

Many states require registration/annual reports if soliciting contributions or meeting revenue thresholds (vary significantly).

Some states mandate independent audit based on revenue/expenses (e.g., NM >$750K expenses, GA >$1M revenue).

Audited financials often required for registration/renewal. Non-compliance can lead to penalties.

Navigating Complexity: CPAs must monitor interconnected regulatory shifts (GAAS, GAGAS, Uniform Guidance, IRS, State) and their cumulative effect on NFP reporting and audit procedures. This is key for compliance and strategic advice.

III. Reporting and Post-Audit Responsibilities

The audit culminates in the auditor's report. This section covers the types of audit opinions, reporting requirements, how nonprofits should address findings, ethical considerations like auditor independence, and the potential for an ongoing advisory relationship with the CPA.

Audit Opinions and Reporting Requirements

CPA firm issues an "opinion" on financial statement accuracy, based on quantitative and qualitative data. The auditor's report (management letter) outlines findings and recommendations.

Four Primary Types of Audit Opinions (Click to learn more):

Unqualified Opinion

Qualified Opinion

Adverse Opinion

Disclaimer of Opinion

Report also details material internal control issues and operating inefficiencies.

Strategic Communication: Report influences stakeholder perception. Unqualified enhances credibility. Others can damage reputation/funding. Clear CPA communication is paramount.

Addressing Audit Findings and Recommendations

  • Board (audit/finance committees) has fiduciary duty to review findings and act.
  • Governance letter outlines issues and recommendations.
  • Material Weaknesses/Significant Deficiencies: Failures in internal controls. Diagnose and address promptly. Can lead to fraud/errors, increase future audit fees.
  • Board should provide written responses to management letter recommendations.
  • Implement improvements (training, software, policies). Track progress; repeat issues are red flags.
  • Conduct quarterly internal reviews for ongoing audit readiness.

Ethical Considerations and Auditor Independence

Independence is cornerstone for reliable/trustworthy statements. CPAs bound by AICPA Code of Professional Conduct (integrity, objectivity, due care, competence, confidentiality).

  • Independence Defined: State of mind permitting attest service without compromised professional judgment.
  • In Practice: Auditors can't perform management responsibilities for client. Avoid relationships compromising objectivity, auditing own work, self-dealing, conflicts, advocacy.
  • Conceptual Framework (AICPA): Identify threats to independence, evaluate significance, apply safeguards.

Upholding Public Trust: For NFPs, auditor ethics/independence are fundamental to credibility. Perceived compromise damages stakeholder confidence. Demonstrate independence in fact and appearance.

Ongoing Client Relationship and Value-Add

  • CPA role extends beyond annual audit; can become trusted advisor.
  • Advise on continuous improvement of internal controls.
  • Assist with financial planning and refining risk management.
  • Help implement robust controls (segregation of duties, cash management, grant tracking).
  • Guide development of financial policies/procedures.

Partnership Benefits: Strengthens operational efficiency, reduces future findings, safeguards assets, allowing NFP to focus on mission.

Conclusion: Elevating Nonprofit Financial Stewardship

Performing a nonprofit financial audit as a CPA is a complex undertaking requiring specialized knowledge, adherence to standards, and an understanding of the mission-driven nature of these organizations. The audit is a dynamic engagement, not a static compliance exercise, influenced by evolving regulations and the need for public trust.

CPAs must navigate a hierarchy of standards (GAAS, GAGAS, Uniform Guidance), staying current with updates like GAGAS quality management and Single Audit thresholds. Rigorous pre-engagement procedures, especially integrity assessment, are vital. A mission-centric risk assessment is key, recognizing threats to public trust and programmatic viability.

During fieldwork, focus extends beyond transactional accuracy to internal controls, revenue recognition (especially restricted funds/grants), functional expense classification, and regulatory compliance (IRS Form 990, state charity rules). The auditor's report is a powerful tool; clear communication of findings and actionable recommendations are crucial. Ethical conduct and independence are non-negotiable.

Ultimately, the CPA specializing in nonprofit audits evolves into a trusted advisor. By integrating technical expertise with a deep understanding of the nonprofit's mission, CPAs contribute significantly to the financial health, transparency, and sustainability of these vital organizations, reinforcing public trust and enabling them to fulfill their societal roles.
