AI compliance has moved from IT's backlog to finance's front page. With the EU AI Act enforcing high-risk AI obligations from August 2026, GDPR already applying to every AI tool processing personal data, and US states like Colorado, Texas, and California enacting their own AI laws, finance teams need a structured compliance framework now. This guide breaks down the five AI compliance risks that matter most to mid-market companies (30 to 500 employees): data leakage from employees pasting sensitive information into AI tools, shadow AI operating outside governance, vendor compliance gaps, data residency concerns, and missing audit trails. It then provides a practical five-step framework for building AI compliance without a dedicated GRC team, covering AI tool discovery, risk classification, vendor certification verification, approval workflows, and ongoing monitoring. The post includes a detailed AI compliance checklist covering pre-purchase due diligence, ongoing monitoring requirements, and annual audit preparation, designed to be useful in real auditor conversations.
