MCKESSON CORP · 2026-08-05 · Importance 38 · Surprise 24

McKesson files tax returns in U.S. federal, U.S. state, and foreign jurisdictions and had $1.6 billion of unrecognized tax benefits as of June 30, 2026. Of that amount, $1.5 billion would reduce income tax expense and the effective tax rate if recognized. The balance represents material exposure to tax authority examinations and changes in the company’s tax position across multiple jurisdictions.
