The core coverage for an accountant, bookkeeper, or tax preparer is Errors and Omissions (E and O) — it responds when a filing error, a missed deadline, bad tax advice, or a math mistake causes a client a financial loss or penalty. Because you hold sensitive client financial data, Cyber is important, and a fidelity bond covers theft when you handle client funds. General liability and a BOP round out the stack. There is usually no license mandate — the driver is your exposure and client expectations.
Accounting and tax work is dense with financial-error exposure: one mistake on a return or in the books can cost a client real money, and the claim lands on you. This guide covers the E and O-centered stack, the cyber and fidelity add-ons, and the differences across CPAs, bookkeepers, and tax preparers. It is general education, not advice for your specific firm.
Errors and omissions — the core coverage
E and O (professional liability) responds to claims that your professional work caused a client a financial loss:
- Filing error — a mistake on a return that triggers an IRS penalty or interest.
- Missed deadline — a late filing that costs the client.
- Bad tax advice — a recommendation that leads to a loss or penalty.
- Bookkeeping/math error — an inaccuracy that flows into financials or a filing.
General liability does not cover these; it covers physical injury and property damage. See GL vs professional liability.
The rest of the stack
Cyber Liability
You hold SSNs, financials, and tax data. Cyber responds to a breach: notification, forensics, and third-party claims — a serious exposure in tax season.
Fidelity Bond / Crime
Covers theft when you or an employee handle client funds (payroll, bill-pay, trust). Often required to win engagements involving client money.
General Liability / BOP
Third-party injury and property damage, plus office property. A BOP bundles GL with property.
Workers Comp
Required in almost every state once you have employees.

Common claims
Accounting sub-niches
CPA, bookkeeper, tax preparer (with a PTIN; seasonal exposure spikes in tax season), enrolled agent, and payroll service. Bookkeepers and independent tax preparers are a large, under-served group — the coverage need is the same E and O + cyber core. Because E and O is usually claims-made, protect your retroactive date and tail. See occurrence vs claims-made.
Frequently Asked Questions
Do accountants and bookkeepers need E and O insurance?
Yes — it is the core coverage. E and O responds when a filing error, missed deadline, bad tax advice, or bookkeeping mistake causes a client a financial loss or penalty. General liability does not cover these professional errors.
Do bookkeepers need insurance too?
Yes. Bookkeepers face the same professional-error exposure — a mistake that flows into financials or a filing — plus cyber exposure from client data. The E and O plus cyber core applies just as it does for CPAs.
Why do tax preparers need cyber insurance?
Because they hold SSNs and financial data, and tax season concentrates the exposure. Cyber responds to a breach with notification, forensics, and third-party claims.
What is a fidelity bond for an accounting firm?
It covers theft of client funds by you or an employee — important when you handle payroll, bill-pay, or client trust funds, and often required to win those engagements.
Is accountant E and O claims-made?
Usually yes. Protect your retroactive date and buy tail coverage when you switch carriers so prior engagements stay covered.
Is insurance required to prepare taxes?
There is generally no state insurance mandate to prepare taxes, though you need a PTIN from the IRS. Insurance is driven by your exposure and client expectations, and many engagements effectively require E and O.
