Accounting & CPA E&O Insurance
Professional liability for accounting firms is driven by the scope of services, the engagement, and the financial consequences alleged when work is missed, misstated, delayed, or outside the client’s expectations.
Start with the policy
- Is coverage claims-made or claims-made-and-reported?
- What retroactive date applies?
- What services are included in “professional services”?
- Do claim expenses reduce the limit?
- What deductible or retention applies?
Claims-made
The reporting trigger matters.
Prior acts
Continuity can preserve earlier work.
Engagement scope
Policy wording should match actual services.
Where claims start
The engagement and the service mix matter.
A CPA firm preparing tax returns, a bookkeeping practice, and a firm performing attest or advisory work do not present the same professional liability exposure. Underwriters typically look closely at the percentage of revenue by service, client industries, engagement controls, prior claims, disciplinary history, and higher-risk engagements.
- Tax preparation and filing
- Bookkeeping and payroll
- Compilation and review work
- Audit and attest services
- Business and management advisory
- Trust or fiduciary services
- Valuation and forensic work
- Investment-related or referral activities
Read the policy
Coverage provisions worth comparing.
- Definition of professional services and whether all current service lines are scheduled or contemplated
- Retroactive date and continuity of prior-acts coverage
- Claim-expense treatment: within limits, outside limits, or subject to a separate sublimit
- Deductible or self-insured retention, including whether defense expense erodes it
- Who qualifies as an insured: firm, partners, members, employees, temporary staff, and predecessor entities
- Extended reporting period options after cancellation or nonrenewal
- Subpoena assistance, disciplinary proceedings, regulatory inquiries, or crisis-response extensions where available
- Exclusions affecting investment activity, fiduciary services, owned entities, commingling, dishonesty, or prior knowledge
Common allegation patterns
Claims usually arise from an engagement, deadline, statement, or advice.
- Missed tax elections, filing deadlines, or extensions
- Alleged errors in returns, financial statements, or reconciliations
- Failure to identify or communicate an issue within the agreed scope
- Advice alleged to have caused a financial loss
- Disputes over the scope of services or responsibility for management decisions
Underwriting file
Applications often drill into higher-risk services.
Beyond revenue and years in business, applications may request revenue by service class, the percentage of public-company or financial-institution work, prior claims or incidents, licensing and disciplinary history, engagement-letter practices, peer review, client concentration, mergers or acquisitions, and whether the firm performs investment, fiduciary, trustee, valuation, or other specialized services.
A lower premium does not mean the same coverage.
When comparing accountants professional liability proposals, review the retroactive date, service definition, defense-cost treatment, retention, exclusions, and any profession-specific endorsements before focusing on price.
