Accountants Errors and Omissions Insurance
Accountants Errors and Omissions Insurance
Professional liability coverage for CPAs, bookkeepers, and accounting firms.
Accountants errors and omissions insurance protects certified public accountants, bookkeepers, and accounting firms against claims alleging negligence in tax preparation, audit work, financial statement preparation, or advisory services. It typically responds to defense costs as well as any settlement or judgment arising from a client's allegation that accounting work was performed incorrectly or incompletely.
Why accountants face concentrated liability
Clients rely on accountants for tax filings, audited financial statements, and advisory work that often has direct financial and legal consequences, from a missed tax deadline generating penalties to an audit opinion that a lender or investor later relies on. When outcomes disappoint a client or a third party who relied on the accountant's work, the accountant is a natural target for a claim even when the underlying business decision was the client's own.
Third-party reliance is a particular concern in this profession because lenders, investors, and regulators may rely on audited or reviewed financial statements without a direct contractual relationship with the accountant, which can expose the firm to claims from parties beyond the immediate client.
Common claim triggers
Frequent allegations include errors in tax return preparation that generate penalties or missed deductions, failure to detect fraud or material misstatement during an audit or review engagement, negligent financial statement preparation, and advisory errors related to business valuation, mergers, or entity structuring.
Claims can also arise from a bookkeeper's data entry errors that cascade into inaccurate financial reporting relied on by a business owner, lender, or buyer during a transaction.
How service type affects exposure
Audit and attestation engagements typically carry higher severity potential than compilation or bookkeeping work because third parties often rely directly on the accountant's opinion, while tax preparation exposure tends to be driven by volume and the complexity of the returns handled.
Firms offering advisory services such as valuation, forensic accounting, or transaction support take on exposure closer to that of a financial consultant, and underwriters typically evaluate each service line separately when pricing the account.
Structuring the coverage
This coverage is typically written on a claims-made basis, so firms should maintain continuous coverage and consider an extended reporting period when retiring a partner, closing a practice, or merging with another firm.
Limits are typically selected based on firm revenue, the mix of audit versus tax versus advisory work, and the size of the largest engagements handled, since a single flawed audit opinion on a larger client can generate outsized exposure relative to routine tax work.
What it typically responds to
- Tax preparation errors. Claims alleging mistakes in filed returns that generated penalties or lost benefits.
- Audit and review failures. Allegations of a failure to detect fraud or material misstatement.
- Financial statement errors. Claims tied to negligent compilation or preparation of financial statements.
- Advisory service errors. Errors in valuation, transaction support, or entity structuring advice.
- Defense costs. Legal expenses defending a covered claim, typically within policy limits.
Common exclusions
- Dishonest or fraudulent acts. Deliberate misrepresentation by the accountant is typically excluded.
- Client's own business decisions. Losses tied purely to a client's independent business judgment are typically excluded.
- Known prior errors. Issues known to the firm before the policy incepted are typically excluded.
- Nonpayment of fees disputes. A standalone fee collection dispute is typically not treated as a covered claim.
