Need more information about managing your business risks?

With more than 23,000 CPA firms insured nationwide, CNA is the number one provider of Accountants Professional Liability (APL) insurance in the U.S. Since 1993, we have been the exclusive Accountants Professional Liability underwriter for the American Institute of CPAs (AICPA) through our managing general underwriter (MGU) partner, Aon Affinity.


We offer a superior customer experience driven by our expert underwriting, world-class claims service and industry-leading risk control capabilities. Our simplified process includes online quotations and a short-form renewal process for small and mid-sized firms.

Accessing our Accountants Program

Our program is mutually exclusive with our MGU partner, Aon Affinity, and 15 exclusive Territorial Administrators (TAs) for local access. While TAs and Aon Affinity do not typically accept sub-produced business, they may engage depending on the account and circumstances. Our team of underwriters is here to help navigate this conversation.
