How to Buy Accounting & CPA Firm Insurance
A step-by-step guide to building the right coverage stack for your accounting & cpa firm business — in the right order.
Start with a Business Owners Policy (BOP)
A BOP bundles general liability + commercial property into one discounted package — typically 20–30% cheaper than buying them separately. For most accounting & cpa firm businesses with a physical location or equipment, this is your foundation.
Add Professional Liability (E&O)
General liability doesn't cover claims that your professional advice or services caused financial harm. Professional liability (also called E&O) fills that gap. Most professional accounting & cpa firm contracts require it. It's almost always a claims-made policy — so understand your retroactive date before switching carriers.
Add Cyber Liability
If your accounting & cpa firm business stores client data, processes payments, or uses cloud software, you have cyber exposure. A breach or ransomware attack costs an average of $200,000+ for small businesses — far more than the annual premium. Cyber liability covers breach response, notification costs, ransomware, and client claims.
Review Your Policy Annually
Business insurance should evolve as your accounting & cpa firm business grows. Review your coverage every year — or whenever you hire employees, buy equipment, add a vehicle, take on larger contracts, or expand to new locations. Underinsurance is as costly as no insurance when a real claim hits.
How to Save on Accounting & CPA Firm Insurance
Proven strategies to reduce your premium without sacrificing the coverage your accounting & cpa firm business actually needs.
💡 Bundle your coverages into a BOP
A Business Owners Policy bundles general liability and commercial property at a 20–30% discount compared to buying them separately. Most accounting & cpa firm businesses qualify. Ask your carrier if you can add specialty coverages as endorsements to keep everything under one policy.
💡 Pay annually instead of monthly
Most carriers charge a 3–8% installment fee if you pay monthly. Paying your premium annually eliminates this fee. On a $2,880/year policy, that's $144+ back in your pocket.
💡 Choose the right deductible
Raising your deductible from $500 to $1,000 or $2,500 typically reduces your GL premium by 10–20%. If your accounting & cpa firm business has cash reserves to cover a moderate out-of-pocket expense, a higher deductible can meaningfully reduce your annual cost.
💡 Maintain a clean claims history
A single claim in the past 5 years can raise your premiums 20–35%. For minor property damage losses you can afford to absorb, paying out-of-pocket protects your claims record. However, always report liability incidents (third-party injury or property damage) and employee injuries to your carrier promptly — these have legal reporting requirements regardless of whether you file a claim. Implement systems to prevent the most common incidents in your industry.
💡 Shop the market every 2–3 years
Insurance carriers reprice risk regularly. A policy that was competitive 3 years ago may not be today — and new carriers may offer better rates for your accounting & cpa firm industry. Working with an independent agent who has access to multiple carriers ensures you're always getting the best available rate.
