Average Accountants Business Insurance Cost (2026 Report)

Accountant and CPA business insurance averages $59 per month, or $707 per year, across the six most common coverage types. Our analysis modeled businesses with one to four employees across all 50 states and Washington, D.C., using policy limits of $1 million per occurrence and $2 million aggregate.

Individual coverage costs range from $15 to $93 per month, with workers' compensation pricing lowest because desk-based accounting carries a low injury-risk class. Cyber insurance anchors the high end, driven by the tax returns, payroll records and financials accounting firms hold. You likely expect professional liability to be your largest cost since it's the coverage the profession is built around. Our data, however, says otherwise: cyber insurance prices above professional liability for a practice like yours. That reflects how much data density shapes financial services business insurance costs alongside professional risk.

Professional liability covers claims tied to the work itself: a missed deduction, a filing error, a financial projection your client disputes or advice that leads to a loss. Most accountants know this coverage by its shorthand, errors and omissions insurance. For your firm, it's the most direct coverage for the risk that defines the profession, and many client contracts will require it before an engagement letter is signed.

Our analysis shows professional liability costs ranging from $61 a month in North Carolina to $82 in Washington, D.C., a $21 monthly gap. The spread is narrower than most other coverage types we analyzed because professional liability pricing for accountants is driven more by your firm's revenue, service mix and claims history than by geography. If your firm offers tax planning or investment-adjacent advisory services, expect your rate to sit toward the higher end of this range regardless of which state you're in.

Cyber insurance covers the response costs, regulatory exposure and client notification obligations that follow a data breach or network incident. Your firm holds some of the most sensitive client data in any profession: Social Security numbers, tax records, bank account information and financial statements. That combination makes accounting firms a target for both opportunistic breaches and targeted attacks on high-value financial data.

We found cyber insurance costs ranging from $79 a month in Alaska to $116 in Washington, D.C., about 1.5 times higher at the top. Several states in our dataset cluster near the low end, which points to a pricing floor rather than a meaningful geographic advantage for your firm. The more consequential variable is your security posture: firms without multi-factor authentication, documented incident response plans or encrypted file storage routinely quote above the national average regardless of which state they operate in.

General liability covers the third-party claims that can surface even in a profession built around paperwork. A client injured in your conference room, damage to a client's property while on your premises, a dispute over something said in a client communication are some of the scenarios general liability is built for. It's also the baseline policy most commercial leases and client contracts will require before your work begins.

Our analysis shows general liability costs for accounting firms ranging from $39 a month in West Virginia to $99 in Washington, D.C., a $60 monthly gap that reflects population density, litigation frequency and local court cost environments rather than anything specific to how your firm operates. If you're in an urban market, signing a commercial lease or serving institutional clients, expect your rate to land toward the higher end regardless of firm size.

Workers' compensation covers the injury and illness claims that arise when your employees are hurt on the job, including repetitive strain injuries, slip-and-fall incidents and stress-related conditions that can occur in an office setting. Most states require it the moment you bring on your first employee, regardless of whether the work is physical.

Our data shows workers' comp costs running from $12 per employee per month in Indiana to $18 in California, about 43% higher at the top of the range. State classification systems and benefit structures account for most of that gap. Accounting work carries a lower injury rate than most industries, so the difference reflects regulatory differences more than occupational risk. If you're planning to hire across multiple states, check each state's rate individually because the spread across the middle of the distribution is narrower than the endpoints suggest.

Commercial property covers the physical assets your firm depends on: office furniture, computers, servers, filing systems and any tenant improvements. The policy pays out against losses from fire, theft, vandalism and certain other events. If you're leasing office space, your landlord will likely require it as a condition of the lease, separate from what the building policy covers.

Our data shows commercial property running from $25 a month in North Dakota to $35 in New York, about 37% higher. Property replacement costs, local construction labor rates and weather-related loss frequency drive most of that difference, so firms in dense urban markets or flood-prone areas tend to quote toward the higher end, while a newer build-out in a lower-cost market is one of the few factors that reliably pulls the rate down.

Commercial auto covers vehicles you use for business purposes: client site visits, IRS office trips, bank runs or any drive where the vehicle is operating in a business capacity rather than personal use. Your personal auto policy typically excludes business-use claims, which makes this coverage relevant if you regularly drive to client locations.

We found commercial auto costs ranging from $47 a month for firms in Iowa to $77 in Washington, D.C., roughly 1.6 times higher at the top. Urban traffic density, accident frequency and state liability minimums account for most of that difference, not how often your firm uses vehicles. If you only drive to client sites occasionally, the exposure is real either way because your personal policy's business-use exclusion applies the moment you're in an accident on a client trip.

Accountants business insurance costs around $59 per month, but treat it as a reference point since your actual premium depends on your credentials, services and location. In accounting, the nature of your work and your client profile shape your premium more than your firm's size.

These questions help you put your quote in context.

1. Where do you fall in the distribution? Your credential type and service scope determine where your firm sits in the distribution. A tax-only EA and a CPA practice running audits can both fall above or below the benchmark for reasons specific to each.
2. Is your quote consistent with your risk profile? Attest services, corporate clients or high limits can push your quote above the benchmark, while narrower terms or a retroactive date that doesn't cover your full history can pull it below. For your firm, that factor matters more than the direction.
3. Which cost drivers apply to your business? Your practice doesn't share the same pricing variables as a solo bookkeeper or a staffed CPA firm. Identifying which apply to your situation, from services and clients to headcount and location, matters more than measuring your distance from the average.

The benchmarks on this page are calibration tools, not targets. What they reveal isn't whether your quote is right or wrong. It's whether the gap has a clear explanation. When it does, you can evaluate it. When it doesn't, that's the question worth investigating.

If you're still working out which coverage types apply to your practice, what your exposure looks like or whether any coverage is legally required, resolve that before focusing on cost. Once you know what applies, cost comparisons become more meaningful.

If you're ready to focus on lowering what you pay, the next step is comparing providers on pricing for your specific profile, from credential type and services to employee count, and identifying which cost levers fit how your firm operates.
