McKesson’s former head of tax joins Vertex

Vertex, the corporate enterprise tax software and services provider, has hired an executive with more than 30 years experience as its new chief taxation officer.

William “Bill” Brennan was formerly vice president of tax for McKesson Corporation, a Fortune 500 corporation that develops and sells healthcare services and information technology. He has also had stints as director of taxes for GE Capital, the world’s largest non-bank financial institution, Con-Way, a freight and logistics company, and MagneTek, a digital power and motion control systems supplier. He is a certified public accountant who has practised at Deloitte and Ernst & Young.

His new company says Brennan “will provide insight and thought leadership” around tax department operations, global tax regulations and policies, and emerging tax industry trends, and will advise Vertex’s board of directors and senior management on the development of the company’s corporate enterprise tax solutions under Vertex® Enterprise.
