What Affects Your Professional Liability Insurance Premium?
Professional liability insurance for accountants is not one-size-fits-all. Here is what moves your premium up or down:
1. Number of employees Adding employees pushes up your rates because more people can make expensive mistakes. A solo accountant pays $1,437 annually, while a two-employee firm pays $315 more.
2. Your specialty area Tax accountants and auditors pay more than bookkeepers because the financial stakes of their errors are higher.
3. Annual revenue Accountants professional liability insurance typically costs about 0.5% to 1% of a firm’s annual revenue. An accounting firm with annual revenue of $200,000 can expect to pay around $1,000 annually.
