Your tax prep business runs smoothly until it doesn't. A missed deadline. A miscalculated deduction. A client who failed to make a payment because you didn't catch it. Suddenly, you're facing a malpractice claim that could destroy everything you've built.

That's where E&O insurance comes in.

Professional liability insurance (also called Errors & Omissions or E&O) protects your practice if a client claims you made a mistake. It covers legal fees, settlements, and judgments — costs that can easily reach six figures. Without it, you're personally liable for the full amount.

If you're running a solo practice or building a tax prep firm, E&O isn't optional thinking anymore. Here's what you need to know.

───

What E&O Insurance Actually Covers
E&O insurance covers claims alleging failure to perform professional duties or that your work caused financial harm to a client. In tax preparation, that typically means:
• Missed filing deadlines that resulted in penalties
• Calculation errors that led to underpayment or overpayment
• Omitted deductions or credits you should have claimed
• Incorrect tax positions that triggered an audit
• Inadequate representation during an IRS dispute
• Advice related to your professional services that caused a loss

The policy covers your legal defense costs, court costs, settlements, and judgments up to your coverage limit.

What It Does NOT Cover

Know the limits. E&O insurance won't cover:

• Fraud or intentional misconduct — If you knowingly help a client evade taxes or falsify documents, you're on your own
• Criminal acts — Insurance doesn't cover criminal liability
• Bodily injury or property damage — That's general liability (a separate policy)
• Tax transactions outside your scope — Coverage may not apply to non-tax business advice
• Dishonest or fraudulent conduct — Most policies exclude this outright

If you're doing the work honestly and making a good-faith mistake, you're covered. If you're cutting corners or worse, you're not.

Claims-Made vs. Occurrence Policies

Claims-made policies cover incidents that occur AND are reported while the policy is active. You need continuous coverage—if your policy lapses, you're exposed for past work. Most tax-prep E&O is claims-made.

Occurrence policies cover incidents that occur during the policy period, regardless of when they're reported. They cost more but don't require tail coverage when you retire or sell your practice.

For a solo preparer starting out, claims-made is fine and cheaper. As you grow, talk to your agent about tail coverage.

Why E&O Matters — Even If It's Not Required

While most states don't legally require E&O insurance for tax preparers, some professional certifications and industry partnerships increasingly recommend or require it.

But the real reason to carry it isn't a legal requirement — it's risk management.

A single malpractice claim can cost $25,000 to defend, even if you win. Add a settlement or judgment, and you're looking at $100,000+ in liability. That's not a business expense. That's a business-ending event if you're uninsured.

How to Get Quotes

  1. Start with specialists — CPE Insurance, CPAinsure, and ProAssurance process tax-specific applications fastest
  2. Have your practice structure, years in business, and annual revenue ready
  3. Compare coverage limits — solo preparers need a $500K/$1M minimum
  4. Ask about tail coverage upfront
  5. Ask about multi-year discounts once you have quotes in hand

The whole process takes 2–3 weeks. Plan ahead.

E&O insurance isn't something you buy because you're paranoid. You buy it because you're professional. It signals to clients that you take your obligations seriously. It costs less than a single tax research tool. And it protects everything you've built from a single bad claim.

If you're building a real practice — not a side gig — this is table stakes.
