Do bookkeepers need professional liability insurance?
Yes, bookkeepers also need professional liability insurance due to common errors such as QuickBooks data entry issues, payroll miscalculations, and multi-client systematic mistakes. Each of these errors can cause clients significant financial harm and possibly other losses.

Be sure to ask an independent insurance agent to help you find the right bookkeeper E&O insurance.
Do tax preparers need professional liability insurance?
Yes, tax preparers can benefit from having professional liability insurance. However, only seven states (i.e., CA, MD, NY, OR, CT, IL, and NV) license tax preparers, and none of them mandate this coverage. Still, tax preparation work comes with the highest claim frequency for E&O insurance.

- Legal defense costs
- Court settlements
- GAAP/GAAS non-compliance
- Failure to detect fraud

What's Not Covered by Accountants Professional Liability Insurance?

- Intentional errors and omissions
- Criminal acts
- Employment practices claims
- Bodily injury to clients
- Personal property damage to clients
Some of these risks are covered by other types of insurance, such as employment practices liability insurance (EPLI). Bodily injury or personal property damage to clients and other third parties would be covered under your business's general liability insurance.
Additionally, data breaches involving client tax records require a separate cyber liability insurance policy. However, it's unlikely that any type of insurance will cover your intentional harm to others or criminal acts.
Key Benefits of Having Accountants Professional Liability Coverage
Besides offering financial protection for you and your accounting firm, accountants professional liability insurance also offers a couple of additional benefits. This coverage can help you and your firm attract clients who require proof that accountants are insured before agreeing to their services.
Some state CPA boards and large corporate clients contractually require proof of E&O coverage before you can begin work. Further, this coverage can grant your firm access to risk management resources, such as consultation and education, depending on the carrier issuing your policy.
Types of Professional Liability Policies
There are two main types of professional liability insurance that accountants can choose from:
- Claims-made policies: These cover claims made during the policy period.
- Occurrence policies: These cover incidents that occur during the policy period, regardless of when the claim is filed.
Occurrence policies can offer your firm greater protection because they still provide financial reimbursement for incidents that occurred during the policy term, even if a client doesn't file a claim until much later. This can be helpful because certain types of errors may not cause obvious harm right away, leading to a claim filed several months later. A local independent insurance agent can help you choose between a claims-made vs. occurrence policy for accounts.
Additionally, you may want to consider adding tail coverage to your policy, which extends the reporting period for claims-made policies. In other words, tail coverage protects professionals against claims filed after the claims-made policy term ends. Retiring accountants, especially, can benefit from tail coverage, as clients can still file claims after the professional has stopped working.
Additional Coverages Accountants Should Consider
Some accountants professional liability insurance policies offer additional coverage options, such as network security coverage, breach response services, investment advisor coverage, and crisis expense reimbursement tailored to evolving business risks. These additional coverages can help protect your firm from network security breaches that may expose your clients' personal and sensitive data to hackers and other unauthorized parties. They can also reimburse your firm for professional services necessary to help your firm recover from a related incident.
Accountants may also want to consider fidelity bonds, which are often required by client contracts. Commercial umbrella insurance is also a good choice for many accountants, because this coverage increases your liability protection beyond the limits in an underlying professional liability policy. Ask your independent insurance agent if any of these coverage endorsements are a good fit for your accounting business.
Why Accountants Professional Liability Insurance Matters for CPA Firms
Having the right type of professional liability insurance tailored to your industry can help protect your firm's reputation and finances from the possibility of an unexpected, costly lawsuit. Even frivolous claims for which you are ultimately not found liable can still be expensive for your business, especially if you must defend yourself in court. Just one of these claims can result in $15,000 to $50,000 in defense costs before it's resolved.
Despite your firm's high professional standards and attention to detail when carrying out professional services, mistakes can still happen. Without the right coverage, just one lawsuit could set your firm back thousands of dollars or even more. That's why it's critical to work with an independent insurance agent to get set up with the right policy tailored to your unique firm before ever opening for business to the public.

- Policy exclusions: Review your policy options to choose one that doesn't exclude coverage for something your firm really needs.
