Retired Partner Tax


Bill Welke focused his practice on the tax aspects of complex business transactions and entities, including: mergers, acquisitions, and leveraged buyouts; venture capital and other private equity investments; formation of private equity funds; joint ventures and partnerships; workouts and restructurings; tax contests and controversies.

Described as having “encyclopedic knowledge of tax structuring strategies” and “adept at cross-border international tax planning in the context of M&A,” one client said that Bill’s “uniquely tailored ideas are nuggets of gold that allow us to differentiate ourselves from competitors,” according to Chambers USA, in which Bill was selected as one of America’s Leading Lawyers for Business in Tax every year from 2003–2019. Bill was also listed as one of The World’s Leading Lawyers for Business in Tax in the 2002 and 2003 editions. Bill has been recognized in The Legal 500 U.S. as well.
