The penalty was the client’s. The claim is yours.

Accountants professional liability

Negligent preparation, advice, audit failure and missed filings.

Without it — Penalties, interest and consequential loss follow an error into the client’s business.

Regulatory defense

Costs of responding to a board, IRS or state investigation.

Without it — A licensing complaint costs real money to answer even when you are right.

Employment practices

Staff claims, in a profession with severe seasonal workload.

Without it — Busy-season overtime and classification disputes are the common pattern.

Does professional liability cover the client’s tax penalty?

The penalty and interest arising from your error, usually yes. The TAX ITSELF, generally no — that is money the client always owed and would have paid anyway, so paying it would put them in a better position than if you had been right. That distinction is where most accountant claims are actually argued, and it is worth being able to explain it to a client before it comes up rather than during. Some forms differ, so it is a wording question worth asking at quote.

We do bookkeeping and payroll as well. Does that change anything?

Yes, and it needs disclosing. Bookkeeping and payroll put you in the client’s money — direct access to accounts, payment runs, tax deposits — which adds a crime and social engineering exposure that a pure compliance practice does not have. It also adds a specific failure mode: missed payroll tax deposits generate penalties that accumulate fast and are attributed to whoever was running the process. Make sure the services you actually perform match what the policy describes.

What about audit and attest work?

It rates well above compliance and tax work, because audit claims are large and are brought by third parties who relied on the opinion — lenders, investors, buyers — rather than only by the client. Firms that perform even occasional attest engagements should say so explicitly; an accountant insured as a tax practice who signs an audit opinion has a coverage problem that only appears when the opinion is challenged.

Is a tax preparer or bookkeeper without a CPA license still insurable?

Yes, readily, and it is a different and cheaper market. Enrolled agents, tax preparers and bookkeepers all get professional liability written for the services they actually provide, and the exposure is real regardless of licensure — a client suing over a botched return does not care whether you held a CPA. What matters is describing the scope honestly, particularly whether you give advice or only process what you are given, since those price differently.
