$2M Professional Liability (E&O) Insurance for Sales Tax and Tax Compliance Consultants

A client asking your sales tax practice for $2M in Professional Liability wants a policy that pays up to $2M for each claim, often as one $2M policy or two layers.

What does a $2M 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 work cost a client money. A $2M clause may read like this (nexus means enough ties to a state that a business must collect its sales tax):

• Each claim and aggregate: the most the policy pays for one claim, and for all claims in one policy year.
• The common mix-up: $2M/$2M and $1M/$2M look alike on a certificate. See Professional Liability 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 work date covered). State audits may look back several years. See retroactive dates.
• After the work ends: a clause like this one may require coverage for three years after the final return. You may need to renew or buy a tail (extra time to report claims).

Who asks sales tax and tax compliance consultants for $2M?

Many smaller practices start with $1M (see $1M Professional Liability for sales tax and tax compliance consultants). $2M tends to appear when one error could touch many states:

• Large online sellers that hand you returns in dozens of states.
• Software and subscription companies that rely on your taxability calls.
• Private equity buyers and lenders that rely on your review before a deal.
• Mid-sized companies outsourcing all indirect tax work under a master services agreement (the main contract for ongoing work).

How is $2M built?

In many cases, $2M is one primary policy (the policy that pays first) with a $2M per claim and $2M aggregate limit. Or a $1M primary plus a $1M excess layer (an extra policy that pays after the primary). The excess should follow form, meaning it uses the primary's terms. If the clause is silent on layers, confirm with the client that primary plus follow-form excess meets it.

CPA firms usually buy accountants Professional Liability. Non-CPA sales tax consultants usually buy Miscellaneous Professional Liability, a general form for service businesses. A commercial umbrella almost never covers Professional Liability.

What will underwriters ask for?

An underwriter is the person at the insurer who decides whether to offer coverage and on what terms. Expect sharper questions at $2M:

• Revenue by service: nexus studies, taxability research, return filing, voluntary disclosures (coming forward to a state to fix missed filings), audit support and deal reviews.
• Your largest clients and the states you file in for each.
• Whether you send tax payments, hold client funds or use client bank or state accounts.
• Whether you map product tax codes or set up tax software.
• Whether buyers or lenders rely on your reports, and whether fees depend on refunds you recover.
• Engagement letters, review steps, prior claims and your retroactive date.

What affects the cost?

• Client size and state count. More states and sales make errors larger.
• Service mix. Deal reviews, taxability advice and software setup usually cost more to cover than registrations.
• Controls and history. Engagement letters, second reviews and clean claims often help.
• Policy terms. $2M/$2M usually costs more than $1M/$2M. A higher retention (the amount you pay on each claim) usually lowers the premium.

Frequently asked questions

Do I need $2M Professional Liability as a sales tax consultant?

Only if your contract or client asks for it. Hypothetically, a nexus study that misses states, or a software setup that codes a taxable service as exempt, could create a $2M claim. Some policies may pay certain penalties or interest a client owes because of your error, usually with a sublimit (a lower cap inside the policy). The tax itself is generally not covered, and wording varies by policy.

Is $1M/$2M enough if my contract says $2M?

Usually not. A $1M/$2M policy pays up to $1M for any one claim, and $2M is the yearly total. If the clause asks for $2M each claim, you usually need $2M/$2M, or a $1M primary plus a $1M follow-form excess layer. Confirm with the client that your setup meets the clause.

I am a sales tax consultant with $1M today. How do I get $2M Professional Liability?

Request new quotes for a $2M policy through Morrow, which can ask carriers to keep your retroactive date and prior acts coverage (coverage for work done before the new policy starts) where the market allows. Keep your current policy until the new one starts, and report anything that could become a claim to your current carrier first.

Will the policy cover a contract where I promised to pay the client's penalties?

Maybe not. Many policies exclude duties you take on by contract beyond what you would owe anyway.
