$1M Professional Liability (E&O) Insurance for Sales Tax and Tax Compliance Consultants

In this guide

For sales tax and tax compliance consultants asked for $1M: Professional Liability (E&O) may pay up to $1M on a covered claim that a mistake in your tax work caused a client.

The short answer

  • A $1M requirement means your Professional Liability (E&O) policy should pay up to $1M for a covered claim that a mistake in your sales tax work caused a client. Many contracts also set an annual aggregate.
  • Check whether the contract asks for $1M/$1M or $1M/$2M. The second number is the aggregate (the most the policy pays for all claims in a year).
  • Morrow can review the contract and your policy, including whether services such as return filing or tax software setup are described on the policy, and help you find $1M in Professional Liability.

What does a $1M requirement mean for sales tax and tax compliance consultants?

Professional Liability (E&O, short for Errors and Omissions) covers claims that a mistake in your advice or work caused a client a financial loss. A typical clause looks like this:

Illustrative contract wording

Consultant shall maintain Professional Liability (Errors and Omissions) insurance covering the sales and use tax compliance, nexus review and return filing services under this Agreement, with limits of not less than $1,000,000 per claim and $2,000,000 in the annual aggregate. If written on a claims-made basis, coverage shall remain in force for three (3) years after this Agreement ends.

Sample wording for illustration only. Your contract's wording controls.

  • Per claim: the most the policy pays for any one claim.
  • Aggregate: the most the policy pays for all claims in a year. Here, $2M, so a $1M/$1M policy falls short.
  • 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 the policy covers). A sales tax error may surface years later. See claims-made vs occurrence.
  • The listed services: check that your policy describes every service the clause names, not just "tax consulting."

Who asks sales tax and tax compliance consultants for $1M?

A $1M request often comes from:

  • Online sellers that sell into many states and hand you recurring returns.
  • Software companies that need help deciding where products are taxable.
  • Manufacturers and distributors with many exempt sales and exemption certificates (forms a buyer gives to show a sale is not taxable) to manage.
  • CPA firms that send sales tax work to outside consultants.
  • Buyers and investors reviewing a target company's sales tax exposure before a deal.
  • Larger companies outsourcing multi-state compliance. Some ask for more (see $2M or $3M).

How is $1M built?

At $1M, the limit is usually one primary policy (the policy that pays first), with no excess layers. A $2M limit mainly gives a larger pool for one claim, which some multi-state sellers ask for. CPA firms usually buy Accountants Professional Liability. Non-CPA consultants often buy Miscellaneous Professional Liability (a form for service businesses without their own policy type) or a tax preparer form. Confirm the form does not exclude tax preparation, return filing or accounting services. Advisory-only work usually fits Miscellaneous more easily.

A commercial umbrella almost never covers Professional Liability. Clients usually cannot be added as an additional insured (a named party on your policy). Where a carrier allows it, it covers only liability from your work. Many clients accept a certificate of insurance (a one-page proof of coverage) instead. It only shows the coverage exists and gives the client no rights under the policy.

Good to know

Defense costs can use up the limit. Many Professional Liability policies pay defense costs inside the limit. On a $1M policy, every dollar spent on lawyers leaves less to pay a settlement.

What will underwriters ask for?

An underwriter is the insurer's decision maker on whether to offer coverage and on what terms. For a sales tax practice, they usually ask for:

  • Revenue by service: nexus reviews (checking where a client has enough ties to a state to owe tax), registrations, return filing, voluntary disclosures (coming forward to a state to settle past unpaid tax) and audit support.
  • How many clients, states and returns you handle, and how you track due dates.
  • Whether you send tax payments for clients or can access their bank accounts.
  • Whether you set up tax software or product tax codes (labels that tell software how each product is taxed).
  • Whether work is paid as a share of refunds you recover.
  • Engagement letters, prior and possible claims, and your retroactive date.

What affects the cost?

  • Service mix. Multi-state filing, deal reviews and software setup usually cost more to cover than one-time registrations.
  • Revenue and client size. Bigger clients can mean bigger losses.
  • Controls. A filing calendar and a second review before returns go out may help.
  • Claims history. Prior claims can raise the price or narrow your options.
  • Aggregate and retention. $1M/$2M usually costs more than $1M/$1M. A higher retention (what you pay on each claim before the policy pays) usually lowers the premium.

Frequently asked questions

Do I need $1M Professional Liability as a sales tax consultant?

Often yes if a client contract asks for it. Check the clause for the limit, the aggregate and the listed services. Hypothetical claim: a nexus review misses a state where an online seller crossed the sales threshold, and a later audit adds penalties and interest.

Will the policy pay the tax my client should have collected?

Often not. Many policies cover a client's claim for penalties, interest and other added costs from your error, but tax owed is often excluded, and some policies limit penalties too.

Is $1M/$1M enough if my contract asks for $1M/$2M?

No, a $1M/$1M policy falls short of a $1M/$2M clause because the aggregate is lower. Request new quotes for a $1M/$2M policy through Morrow, which can ask carriers to keep your retroactive date and prior acts coverage (cover for past work before the new policy starts) where the market allows. Report anything that could become a claim to your current carrier before that policy ends.
