Compliance
Who requires Accounting & Tax Preparation Practices
- Accounting and tax preparation practice insurance is required by the businesses, individuals, and institutions that rely on financial statements and tax filings and embed professional liability minimums in engagement letters.
- Lenders and investors relying on audited or prepared financials expect the firm to carry E&O.
- State boards of accountancy that license CPAs expect coverage behind the license, and professional networks and franchisors may require it.
- Banks reviewing financials, and clients in disputes, expect the firm to stand behind its work, and cyber assurances are increasingly demanded given the sensitive financial data handled, making accounting and tax practice insurance a condition of engagements and licensure.
Carrier standard. Carrier must have an AM Best Rating that meets the required Letter and Financial Size ratings.
Advocate runs these checks automatically for the brokers who place professional & business services coverage.
Exclusions
What Accounting & Tax Preparation Practices does not cover
- In its current form, the accounting firm program brings together Auto Liability, General Liability, Professional Liability, Cyber Liability, Cyber Business Interruption, Worker's Compensation, a Fidelity Bond, and property lines.
- Neither Directors and Officers Liability nor Employment Practices Liability is included.
- Because the Professional and Cyber Liability policies are written on a claims-made basis, engagements and incidents predating the retroactive date, claims first reported after expiration without tail coverage, and matters known before inception are excluded.
- Client financial losses beyond the firm's own negligence, penalties and interest a client owes tax authorities except where specifically covered, fraudulent or dishonest acts, and contractual liability assumed beyond the firm's own negligence generally fall outside coverage.
Risk advisory
Typical coverage gaps in Professional & Business Services
Accounting firms carry professional liability as their defining exposure, with claims involving malpractice, negligence, errors and omissions, and breach of contract in tax and financial work.
- Tax and audit errors can surface after filing deadlines and audits, so align the E&O retroactive date with the firm's history and buy tail coverage before switching carriers or retiring partners.
- Accounting and tax preparation practice insurance includes Cyber Liability, which is important given the sensitive financial data handled; confirm it responds to breaches, ransomware, and social-engineering fraud, and that funds-transfer fraud is addressed under crime coverage, since accounting firms are frequent targets of payment-diversion schemes.
- Verify whether penalties-and-interest coverage is included for qualifying errors.
- As the firm grows and adds partners, add Directors and Officers and Employment Practices Liability, and confirm engagement-letter indemnities align with available limits.
FAQ
Frequently asked questions
What insurance do accounting and tax firms need?
Accounting and tax preparation firms need professional liability, cyber liability, a fidelity bond with crime coverage, general liability, and workers' compensation. Professional liability addresses malpractice and errors, cyber protects sensitive client financial data, and crime and social-engineering coverage guard against payment-diversion fraud these firms frequently face.
Why do accounting firms need professional liability insurance?
Accounting firms need professional liability insurance because their reliance on precise financial and tax work exposes them to malpractice, negligence, errors and omissions, and breach-of-contract claims. E&O funds defense and damages when a client alleges a filing, audit, or financial statement was wrong, an exposure general liability does not cover.
Do accounting firms need cyber insurance?
Yes. Accounting firms hold extensive sensitive financial and personal data and are frequent targets of phishing and payment-diversion fraud. Cyber liability funds breach response, notification, and ransomware, and firms should confirm social-engineering and funds-transfer fraud are addressed under crime coverage, since these losses fall outside professional liability.
Does accountant E&O cover tax penalties owed by a client?
Accountant professional liability may cover penalties and interest a client incurs due to the firm's error, but this is often limited or endorsed rather than automatic. Accounting firms should confirm whether their E&O includes penalties-and-interest coverage, since clients frequently seek recovery of those amounts after a filing mistake.
