What is Accounting, Audit and Bookkeeping Insurance?
Accounting, audit and bookkeeping insurance (often marketed as professional liability or E&O) helps cover claims arising from errors, omissions, or negligent acts in financial services. Coverage may respond to client demands for damages, defense costs, and settlements tied to accounting mistakes, faulty audits, or bad tax advice.
Who needs it
Typical buyers include CPA firms, independent accountants, auditors, small bookkeeping companies and freelance bookkeepers. Organizations that provide payroll processing, tax preparation, or outsourced finance functions also commonly purchase this coverage, often alongside commercial liability and cyber liability protections.
What it typically covers
- Alleged negligence in financial reporting, auditing opinions, or tax filings.
- Claims of breach of fiduciary duty or contract tied to financial services.
- Defense costs for legal representation and settlement expenses.
- Cyber incidents that lead to client financial loss when cyber liability is included or purchased as a separate add-on.

Common exclusions or limitations
Policies often exclude intentional wrongdoing, criminal acts, or claims covered by other specific policies. Typical limitations relate to prior-acts, contractually assumed liabilities, and certain regulatory fines. Underwriting factors and specific policy language determine whether a claim is covered, so review exclusions carefully.
Factors that influence cost
Premiums depend on firm size, revenue, scope of services, claims history, staff qualifications, and the amount of limits and deductibles chosen. Risk management practices—such as peer reviews, documented procedures, and cybersecurity controls—can lower underwriting risk and influence pricing.
Proof of insurance & compliance
Clients and contracting parties may request certificates of insurance or specific endorsements (for example, additional insured status or a professional services endorsement). Maintaining up-to-date proof of insurance helps meet contractual obligations and shows practical risk controls.
