Accounting Firms Insurance Requirements
Accounting Firms face specific insurance requirements from clients, regulators, and licensing authorities. We help you understand what coverage is required, what limits you need, and how to get compliant quickly.
Check Requirements →Insurance Requirements for Accounting Firms
Insurance requirements for accounting firms come from three overlapping sources: state and federal regulations, client contracts, and industry licensing standards. Missing any one creates gaps that can cost you contracts, licenses, or operating authority.
Key regulatory standard: OSHA general office standards apply (29 CFR 1910.22 walking-working surfaces, 1910.303 electrical). State CPA licensing boards mandate professional liability coverage as a condition of practice in many states
What Are the Required Coverages and Minimum Limits?
General Liability — classified under ISO GL class code 41675 (Accounting/CPA firms), required at $1M/$2M minimum. Additional insured endorsements (CG 20 10 (Additional Insured — Owners, Lessees or Contractors — Scheduled), CG 20 37 (Additional Insured — Owners, Lessees or Contractors — Completed Operations), and CG 20 26 (Additional Insured — Designated Person or Organization)) required by most contracts. (Source: ISO)
Workers Compensation — classified under NCCI 8810 (Clerical office employees — CPA/accounting firms), mandatory in nearly all states. Employers liability $500K/$500K/$500K standard; many contracts require $1M. (Source: NCCI)
Commercial Auto — $1M CSL on ISO CA 00 01 with hired and non-owned coverage for accounting firms operating business vehicles.
Umbrella/Excess — $1M–$5M depending on contract requirements and risk exposure.
Required endorsements: Waiver of subrogation (CG 24 04 (Waiver of Transfer of Rights of Recovery Against Others to Us)), primary and noncontributory (CG 20 01 (Primary and Noncontributory — Other Insurance Condition)). (Source: ISO Commercial Lines Program)
What regulatory standards apply to Accounting Firms?
Key regulatory framework: OSHA general office standards apply (29 CFR 1910.22 walking-working surfaces, 1910.303 electrical). State CPA licensing boards mandate professional liability coverage as a condition of practice in many states
Insurance compliance and regulatory compliance are linked for accounting firms. OSHA violations can trigger carrier audits, premium adjustments, and in severe cases, policy cancellation. Maintaining documented compliance is both a legal obligation and an insurance cost control strategy.
What Do the Numbers Say About Accounting Firms Insurance?
Accounting firms have one of the lowest physical injury rates at 0.4 per 100 FTE, but face professional liability claims averaging $150,000+ per incident from audit failures, tax preparation errors, and financial reporting mistakes (Source: BLS SOII, CNA Professional Liability)
Professional liability from audit opinions, tax preparation errors, and financial advisory mistakes is the dominant risk — physical injuries limited to ergonomic strain and office slip-and-fall. Average claim severity: Average CPA E&O claim: $148,000 including defense costs (Source: AICPA/CNA Professional Liability data). Carriers use this data to set base rates for accounting firms — businesses with documented safety programs and clean claims histories access rates 15–30% below the standard.
Classification detail: Workers compensation under NCCI 8810 (Clerical office employees — CPA/accounting firms) at base rates of $0.15–$0.40 per $100 of payroll. General liability under ISO GL class code 41675 (Accounting/CPA firms). (Source: NCCI, ISO)

Required Coverage
General Liability Insurance
Required by office lease agreements and client contracts. Professional service GL limits of $1M/$2M are standard. Landlord additional insured endorsements are required in virtually every commercial lease. While professional firms face lower GL exposure than manual trades, slip-and-fall claims at offices and client property damage (including data loss treated as property damage) are covered under GL. Some firms combine GL with professional liability through a Management Liability package.
Directors & Officers (D&O) Insurance
Required for firms with outside investors, advisory boards, or partnership structures. D&O coverage protects firm leaders from claims alleging mismanagement, breach of fiduciary duty, or regulatory violations. Employment Practices Liability (EPLI) is typically bundled with D&O for professional firms, covering wrongful termination, discrimination, and harassment claims. Partnership disputes, shareholder derivative actions, and regulatory investigations are covered under D&O policies.
Workers Compensation Insurance
Required in all states for firms with employees. Professional service WC classification codes (8810 — Clerical, 8742 — Outside Sales) carry low rates compared to manual trades, but coverage is mandatory. Remote work arrangements create multi-state WC compliance obligations as employees work from different jurisdictions. Firms using 1099 contractors face misclassification risk — if a contractor is reclassified as an employee, WC coverage gaps create significant liability.
Cyber Liability Insurance
Increasingly required by clients whose data professional firms access or process. Firms handling client financial data, personal information, or intellectual property face contractual cyber coverage mandates of $1M-$5M. SOC 2 Type II certification — now required by many enterprise clients — incorporates cyber insurance as a complementary control. Privacy regulations including CCPA, GDPR, and state breach notification laws create liability exposure that drives cyber coverage requirements.
Professional Liability (E&O) Insurance
The primary insurance requirement for professional service firms. Client contracts require E&O coverage at limits ranging from $1M to $10M depending on engagement size and industry. State licensing boards for architects, engineers, CPAs, and attorneys may require proof of E&O coverage for license renewal. Claims-made policy forms are standard for professional liability — firms must understand retroactive dates and tail coverage obligations. SOC 2 and ISO 27001 compliance frameworks reference E&O coverage as a risk management control.
