Accounting Firm Insurance: What You Need to Know

Accountants handle their clients' most sensitive financial data — from tax returns to payroll records to financial statements. A missed filing deadline, tax preparation error, or data breach can lead to significant client losses and expensive lawsuits. The right insurance protects your practice and your reputation.

Essential Accounting Firm Coverages

Professional Liability (E&O) — tax errors, missed deadlines, bad financial advice
Cyber Liability — client data breaches, ransomware, identity theft
General Liability — client injuries at your office, property damage
Workers' Compensation — employee injuries (required with employees)
Business Owner's Policy (BOP) — bundled property + liability for office-based firms
Employment Practices Liability — wrongful termination, discrimination claims

How Much Does Accounting Insurance Cost?

Firm Size	Annual Cost Range
Solo CPA / Bookkeeper	$800-$2,500
Small Firm (2-5 CPAs)	$2,500-$8,000
Mid-size Firm (5-20 professionals)	$8,000-$25,000
Large Firm (20+ professionals)	$25,000-$75,000+

E&O premiums depend heavily on the services you offer (audit vs tax prep vs advisory), your client base size, and your claims history. Firms providing audit and attestation services pay significantly more.

Why E&O Insurance Is Essential for Accountants

Tax errors can cost clients thousands in penalties and interest. Missed filing deadlines trigger IRS penalties your client didn't expect. Even accurate work can lead to claims if a client suffers losses and looks for someone to blame. E&O insurance covers your legal defense and any settlements — even for baseless claims.
