KPMG vs Deloitte: overview

KPMG

KPMG was formed in 1987 through the merger of Peat Marwick International and Klynveld Main Goerdeler, and its member firms employ around 275,000 people. In December 2025 KPMG International announced ISO/IEC 42001 certification for its own AI management system, audited by Schellman; member firms in Australia, Spain, India, and the US had certified earlier. Its Trusted AI approach covers governance design, risk classification under the EU AI Act, controls testing, and assurance. For a CFO or chief risk officer who needs advice that an audit committee will accept, few firms have a larger bench. Auditor-independence rules can bar it from advising its own audit clients. Check that first.

Deloitte

With more than 460,000 people and roots in an 1845 London accounting practice, Deloitte has the widest reach of any firm on this list. Its AI advisory sits next to risk and regulatory teams, which helps banks, insurers, and health systems that must document how each model is governed. Deliverables tend to be thorough and heavy. Expect large teams, long timelines, and a natural path into Deloitte's own implementation work.
