The most important SOC 2 AI governance lesson for 2026 is counterintuitive: waiting for the proposed criteria to become mandatory is itself an audit risk. The AICPA SOC 2 Working Group is seeking public comment on proposed 2027 SOC 2 Trust Services Criteria and Description Criteria, with comments open through Jan. 15, 2027 and an expected effective date for engagements beginning on or after Dec. 31, 2027 if approved, with early adoption permitted AICPA & CIMA, SOC Suite of Services.
