Tax Preparer Insurance Cost: Ranges + Calculator
Our own quote data shows tax-preparation firms most request two coverages a generic business policy never leads with: errors and omissions (professional liability) and cyber. E&O responds when a mistake on a return or a missed deadline leaves a client facing penalties and interest; cyber matters because preparers hold Social Security numbers and financial data — and under the FTC Safeguards Rule, tax preparers are treated as "financial institutions" legally required to maintain a written information-security program. Cyber insurance is the financial backstop to that duty.
As an industry-typical estimate, a small tax-prep firm runs roughly $1,000–$4,000+/year across errors & omissions, cyber, a BOP or general liability, and payroll-rated workers' compensation — more with more preparers or year-round advisory work. No insurance bureau publishes tax-prep premiums, so every dollar here is an estimate; each coverage fact is sourced to a named authority (III, FTC).

Industry-typical market ranges
Sourced from III, NCCI, ISO, NAIC, BLS, FMCSA, FDA, NRA — government and bureau publications, not from our quote form
Coverage lines a tax-preparation firm typically carries (industry-typical estimates):
- Errors and omissions (professional liability): the co-defining line — defends a mistake on a client's return, a missed filing deadline, or the resulting penalties and interest. III professional liability.
- Cyber: preparers hold SSNs and financial data; the FTC Safeguards Rule requires a written security program, and cyber covers breach response and notification. FTC Safeguards Rule, III cyber liability.
- General liability / BOP: third-party injury and property damage, bundled with office property. III commercial general liability.
- Workers' compensation: required in most states once the firm hires (seasonal preparers count). III workers comp.
Number of preparers, advisory vs. seasonal mix, and volume of client PII are primary rating factors.
