Accountant Business Insurance
Accountant business insurance protects CPAs, tax preparers, bookkeepers, and accounting firms from the cost of a client lawsuit, a data breach, an injured office visitor, or an employee claim. Your largest exposure usually is not a slip in the lobby. It is the missed election, the transposed figure, or the piece of advice that costs a client money.
This guide is written for solo preparers and multi-partner firms doing attest and non-attest work, tax prep under Circular 230, audit and assurance, payroll, and advisory. If you sign engagement letters, hold a PTIN, sit for peer review, or issue SOC reports, the coverages below apply to you.
Here is what most accounting practices carry or are asked to show proof of:
- Professional liability (errors and omissions), the core coverage for any tax or accounting work
- General liability, usually packaged with your office property in a business owner's policy
- Workers' compensation once you hire employees, with rules that vary by state
- Cyber liability, increasingly required by clients, banks, and your own data-security duties
- An ERISA fidelity bond if you handle a client's retirement plan funds
General Liability Insurance for Accountants
General liability insurance covers third-party bodily injury and property damage, such as a client tripping in your office or a staff member damaging a client's equipment during an on-site visit.
FAQ: Does general liability cover a tax mistake? No. Financial losses from your professional work fall under errors and omissions coverage, not general liability.
Expert insight: Watch the "personal and advertising injury" part of the policy. A disparaging comment about a competing firm, or a marketing claim that crosses a line, can trigger a defense here. If you lease space, confirm "damage to premises rented to you" matches your landlord's lease language.
Business Owner's Policy (BOP) for Accountants
A business owner's policy bundles general liability with property coverage for your office, computers, furniture, and records, and usually adds business income coverage if a covered event shuts you down.
FAQ: Do I need a BOP if I work from home? Often yes. Homeowners policies typically exclude business property and client liability, so a BOP or a home-based business endorsement fills that gap.
Expert insight: Standard BOP forms cap "valuable papers and records" and "electronic data" at low sublimits. For a firm storing years of client files and software, ask your agent to raise those limits and to add business income with extra expense, which keeps payroll moving if you relocate after a loss.
Commercial Auto Insurance for Accountants
Most accountants do not own a fleet, but they drive. Commercial and hired or non-owned auto coverage responds when you, or an employee using a personal car for work, cause an accident while running client errands.
FAQ: Will my personal auto policy cover a work drive? Often not. Personal auto carriers may deny a claim that happened during business use, which is why hired and non-owned auto coverage matters.
Expert insight: If staff drop off returns or visit clients in their own vehicles, add a hired and non-owned auto (HNOA) endorsement, frequently attached to the BOP. It protects the firm's assets when an employee's personal limits run out after an at-fault crash.
Excess Liability Insurance for Accountants
Excess liability, sometimes sold as an umbrella, adds a layer of limits on top of your underlying general liability, auto, and, in some cases, professional liability, for large claims that blow through the base policy.
FAQ: Does an umbrella extend my E&O limit? Not automatically. Many umbrellas exclude professional services, so confirm whether you need a dedicated excess professional liability layer.
Claim example: An Illinois firm faced a malpractice suit after a flawed valuation in a partnership buyout. Damages and defense climbed past the $1 million primary E&O limit. Because we had placed a matching excess professional liability layer, the additional $1.2 million in exposure was covered rather than landing on the partners personally.
Professional Liability Insurance (E&O) for Accountants
Professional liability insurance, also called errors and omissions or E&O, is the coverage accountants need most. It pays defense costs and damages when a client alleges negligence, a calculation error, a missed deadline, or bad advice. See our accountant professional liability page for a deeper breakdown.
FAQ: Is E&O required for accountants? Statute rarely requires it, but clients, lenders, and many engagement contracts do, and some state boards ask you to disclose whether you carry it.
Claim example: A California CPA missed an S-corporation election window for a new client, triggering IRS penalties and a higher tax bill. The client sued for the difference. Defense plus settlement came to roughly $95,000. The claims-made E&O responded because the work fell after the policy's retroactive date and the claim was reported on time.
Workers' Compensation Insurance for Accountants
Workers' compensation pays medical bills and lost wages when an employee is hurt or becomes ill on the job. For office-based staff, payroll typically rates under a clerical class, and our professional services workers' comp page covers the basics.
FAQ: Do I need it for one employee? In most states, coverage is required once you have any employees, though triggers and owner rules differ.
Expert insight: Accounting staff usually fall under NCCI class code 8810 (Clerical Office Employees), one of the lower-cost workers' comp classifications. If a client contract demands a waiver of subrogation, your carrier can add that endorsement. Owners and officers can often elect in or out, which changes your premium and your own protection.
Surety and Fidelity Bonds for Accountants
Most accountants do not need a construction-style surety bond, but bonding matters if you touch other people's money. The common one is an ERISA fidelity bond, required when your firm handles funds for a client's retirement plan. Our bonds page explains the categories.
FAQ: How big does an ERISA bond have to be? Generally at least 10% of the plan funds handled, with a $1,000 minimum and a $500,000 maximum, or $1,000,000 for plans holding employer securities.
Expert insight: An ERISA fidelity bond is not the same as fiduciary liability insurance. The bond protects the plan against fraud or dishonesty by people who handle its funds, while fiduciary coverage defends against mismanagement claims. Add an inflation guard provision so the bond keeps pace as plan assets grow, and make sure the plan is named on the bond.
Other Coverage Accountants Often Need
The eight core lines rarely cover every modern exposure. For accounting firms, these add-ons close the most common gaps:
- Cyber liability: Pays for ransomware, breach notification, credit monitoring, and funds-transfer fraud. Because the IRS and FTC treat tax preparers as data custodians, most underwriters now expect multi-factor authentication and a written security plan before they bind. A Georgia firm we insure had tax-season files encrypted by ransomware; cyber coverage handled restoration and client notice at about $70,000.
- Employment practices liability (EPLI): Defends claims of wrongful termination, discrimination, or harassment by employees, an exposure that grows with every hire.
- Directors and officers (D&O): Protects firm leadership against claims tied to management decisions, relevant once you take on partners or a board.
- Crime and employee dishonesty: Covers theft of your own or client money by an employee, separate from the plan-specific ERISA bond.
- Valuable papers, data restoration, and equipment breakdown: Higher sublimits or standalone coverage for the records and hardware your practice runs on.
State Requirements for Accountant Insurance
Two things drive what you are legally required to carry, and both vary by state. Verify specifics with your state agency before relying on any general rule.
- Workers' compensation: Required in nearly every state once you have employees. Texas lets most private employers opt out. North Dakota, Ohio, Washington, and Wyoming require coverage through a state fund rather than a private carrier. A few states set a minimum employee count or treat owners and officers differently.
- Professional liability (E&O): Generally not mandated by statute for accountants, but often required by clients, lenders, franchise or network agreements, and some state boards of accountancy, which may ask you to disclose whether you carry it.
- Cyber and data security: Not a state insurance mandate, but federal rules under the Gramm-Leach-Bliley Act and FTC Safeguards Rule require tax preparers to maintain a written information security plan, and several states layer additional duties on top.
Sources to confirm your state's rules: your state Department of Insurance, your state Board of Accountancy (via NASBA), and your state workers' comp agency.
