Does general liability cover a bad tax return?

No. General liability covers third-party bodily injury or property damage, not financial harm from professional advice. Errors in tax preparation or financial consulting typically fall under professional liability insurance instead.

How much professional liability coverage should a small firm carry?

This depends on the size of client accounts and the complexity of services offered. Firms handling larger client revenues or audit work generally carry higher limits, and an agent can help match limits to typical claim sizes in your practice area.

Are seasonal or part-time staff covered under workers' comp?

In most states, workers' compensation requirements apply once a firm has employees, including seasonal tax-season hires, though rules vary by state and worker classification. Misclassifying seasonal staff as contractors can create gaps in coverage.

What happens if a client's data is stolen from our systems?

A cyber liability policy typically helps cover breach investigation, client notification, credit monitoring, and related legal costs. Without this coverage, those expenses generally come directly out of the firm's pocket.

What underwriters look at

Accountants and CPAs are trusted with clients' most sensitive financial information, and a calculation error, missed deadline, or overlooked tax filing can lead to real financial harm for a client and a liability claim against the firm. Tax season compresses a year's worth of client work into a few frantic months, raising the odds of an oversight even at well-run firms.

Accounting firms also sit on a goldmine of personal and financial data, from Social Security numbers to bank account details, making them frequent targets for phishing and ransomware attacks. A breach can be costly not just in remediation expenses but in the erosion of the client trust that the entire business is built on.

Many firms operate out of leased office space and interact with clients in person for document review and consultations, adding standard premises liability to the mix. As firms grow and add staff, employment practices exposure and payroll-related obligations also become part of the picture.

Errors in tax or financial work

A miscalculated return, missed deduction, or late filing can expose a firm to claims for the resulting penalties or financial loss suffered by the client.

Client data breaches

Firms store extensive personal and financial records, and a cyberattack can trigger notification costs, regulatory exposure, and reputational harm.

Seasonal workload pressure

Tax season concentrates workload and increases the chance of oversight, making quality-control failures a recurring source of claims industrywide.

Client premises visits

In-office meetings and document handoffs create ordinary slip-and-fall or property damage exposure common to any professional office.
