$3M Professional Liability (E&O) Insurance for Non-CPA Accountants

For non-CPA accountants, a $3M Professional Liability requirement means a client wants your bookkeeping, payroll or tax work covered up to $3M per claim, often with a primary policy plus follow-form excess.

What does a $3M requirement mean for non-CPA accountants?

Professional Liability (E&O, short for Errors and Omissions) covers claims that a mistake in your professional work caused a client a financial loss. A $3M clause might read like this:

• Per claim and aggregate: the most paid for one claim, and for all claims in a policy year. See limits explained.
• Claims-made: the policy covers claims made and reported while it is active, for work done on or after the retroactive date (the earliest date of work covered).
• Primary plus excess: the last sentence allows stacked policies. If your clause is silent, confirm with the client that primary plus follow-form excess meets the clause.

Who asks non-CPA accountants for $3M?

Most small practices are asked for $1M or $2M. A $3M clause usually appears when the client's money at risk is larger, and some clients ask for $5M. It often comes from:

• Larger companies outsourcing finance work, such as month-end close or controller work.
• Lenders and investor-backed companies that rely on your books for loan reporting or owner updates.
• Multi-location groups, such as franchise owners or medical groups, where you run payroll for many entities.
• CPA firms or outsourcing providers that pass their own client's limit down to you as a subcontractor.

How is $3M built?

A primary policy pays first. An excess policy pays only after the primary limit is used up. "$2M xs $1M" means a $2M layer that sits above the first $1M.

The excess should follow form, meaning it adopts the primary policy's terms. Every layer should share the same retroactive date, policy period and named insured (the business listed on the policy). CPA firms usually buy Accountants Professional Liability, often from dedicated programs. Non-CPA bookkeepers, tax preparers and accountants are often placed on a Miscellaneous Professional Liability form or a carrier's own bookkeeper or tax-preparer form. Payroll-heavy or funds-handling practices may need a payroll-service form and separate crime coverage (cover for theft of money). The excess layer should follow whichever primary form is used.

What will underwriters ask for?

An underwriter decides whether to offer coverage. At $3M, underwriters may ask for:

• Revenue split by service: bookkeeping, individual tax, business tax, payroll, sales tax filings, outsourced controller work and advisory.
• The client requiring $3M: its size, industry, the services you provide and the contract value.
• Whether you sign checks, move client money or remit payroll taxes, and the controls you use (such as dual approval).
• Return volume and how you track deadlines and extensions.
• Review steps before filing, and confirmation that you do not issue audit or review reports.
• Signed engagement letters, loss runs (a report of past claims) and your current policy with its retroactive date.

What affects the cost?

• Service mix. Payroll, outsourced controller and business tax work usually cost more to insure than basic bookkeeping.
• Control of client funds. Paying bills or remitting taxes for clients adds risk underwriters weigh closely.
• How the $3M is built. The primary layer often costs the most per $1M of limit.
• Revenue, client size and claims history. Bigger engagements and prior claims usually raise the price of each layer.
• Retention and defense terms. Retention works like a deductible. A higher one usually lowers premium. Defense outside the limit usually costs more.

Frequently asked questions

Do I need $3M Professional Liability as a non-CPA accountant?

Only if your contract or client requires it. Most small practices are asked for $1M or $2M.

I have a $1M policy. How do I get to $3M as a non-CPA accountant?

Request new quotes through Morrow, either for a new $3M primary policy or for excess layers above a primary. Morrow can ask carriers to keep your retroactive date and prior acts coverage (cover for past work done before the new policy starts) where the market allows. A commercial umbrella almost never helps, because it usually excludes accounting, payroll and tax services. See does an umbrella cover Professional Liability. Report known incidents to your current carrier before that policy ends.

Can a client be added as additional insured on my $3M Professional Liability policy?

Usually not on Professional Liability. Many clients accept a certificate of insurance (a one-page proof of coverage) that lists every layer. Check what your contract asks for.

What kind of claim could reach $3M for a non-CPA accountant?

A hypothetical example: a payroll provider for a multi-location group misses tax deposits for several quarters, and the client faces penalties and interest across many entities. Policies differ on penalties and interest, so have that wording reviewed.
