What CPA Insurance Typically Includes

We partner with top-rated carriers to develop insurance plans that support CPAs across all practice areas.

Your coverage may include:

Professional Liability (Errors & Omissions)

Also known as CPA professional liability insurance, this coverage protects you if a client claims that your services have caused them financial harm. It's the core of any CPA insurance plan and applies regardless of whether you're doing tax preparation, auditing, or consulting. Many clients will require proof of this before working with you.

Cyber Liability Coverage

Even small firms handle personal and financial data. If your network is hacked or client files are compromised, cyber liability insurance helps cover response costs, notification expenses, legal fees, and more. With data protection laws tightening, this coverage is becoming essential.

General Liability Insurance

This covers physical risks, such as client injuries at your office or accidental damage to another person’s property. Even if you don’t have a storefront, general liability may be required for leases or contracts.

Business Owner’s Policy (BOP)

A BOP bundles general liability and property coverage into one policy. This is a cost-effective way to protect your office space, equipment, and day-to-day operations. We customize your plan based on how and where you work.

Workers’ Compensation

If you have employees, Wisconsin law requires you to carry workers' compensation insurance. It covers medical costs and lost wages in the event of on-the-job injuries or illnesses.

Employment Practices Liability

If you’re managing a team, this coverage can protect you from claims related to wrongful termination, discrimination, or harassment. It provides an additional layer of legal support for your firm.

Why CPAs Need Specialized Insurance Coverage

Accounting is about trust. When you handle sensitive data, file financial documents, or advise on tax and audit matters, even a small oversight can result in a claim.

CPA insurance is built to cover:

Professional mistakes or advice that results in financial loss
Allegations of negligence or omissions
Data breaches and cybersecurity events
Client disputes over deliverables
Workplace or property-related incidents

Your clients rely on you to get things right. However, if something goes wrong, your insurance coverage steps in, helping to cover legal costs, settlement expenses, and potential damages, so your business remains stable.

Tailored Coverage For Every Stage Of Your Practice

Whether you’re newly licensed or have decades of experience, we adjust your CPA insurance to match your specific needs. We can provide scalable coverage as you grow, from a single professional working remotely to a multi-employee firm managing corporate accounts.

Our team helps you evaluate:

Current and future client contract requirements
Risks related to audits, advisory services, and bookkeeping
On-site versus remote operations
Staff structure and payroll
Local and state legal requirements

You don’t need to be an insurance expert. We’ll explain the options clearly and help you choose what’s appropriate without over-insuring.

Why Liability Insurance Isn’t Optional For CPAs

Even if you run a small, careful practice, claims can still happen. Misunderstandings over tax filings, missed deadlines, or data issues can quickly turn into expensive legal battles. CPA liability insurance ensures you’re not footing the bill out of pocket.

Some CPAs wonder, “do I need business insurance if I have an llc?” The answer is yes. While an LLC limits personal liability in many cases, it doesn’t protect your business from client claims, lawsuits, or operational risks. Business insurance adds that essential layer of security that your legal structure alone can’t provide.

You can learn more about the limits of LLC protection in our guide: Do I need business insurance if I have an LLC?

Understanding The Role Of Commercial Insurance In Accounting

Many CPAs think they’re too small for commercial coverage, but that’s not the case. Insurance doesn’t just protect against lawsuits. It can cover lost data, broken equipment, and even interrupted income due to covered incidents.

If you’re unsure how insurance works in a business context, we break it down in our overview of what is commercial insurance, including what coverage types are relevant for service-based businesses like yours.

Frequently Asked Questions

What types of insurance should a CPA carry?

Most CPAs need professional liability, general liability, and cyber liability. Depending on your practice, you may also need property, workers’ comp, or employment practices coverage.

Does Wisconsin law require CPA insurance?

Not always legally required, but many clients, contracts, and licensing boards expect or mandate it. It’s also strongly recommended to protect against lawsuits and claims.

How much does CPA insurance cost?

Premiums vary based on firm size, services offered, revenue, and coverage limits. We help you compare options and apply every relevant discount.

Does professional liability insurance for CPAs cover data breaches?

Not typically. You’d need a separate cyber liability policy. We can combine both into a single plan for convenience and cost savings.

Yes. We offer flexible plans for remote CPAs, part-time consultants, and small firms. You’ll only pay for the protection you actually need.
