Timothy G. Schally

Practice Group Chair, Tax


Tim provides strategic counsel on tax matters contested by the Internal Revenue Service, the Wisconsin Department of Revenue, and the taxing authorities of other state and local jurisdictions. Contested matters, for Fortune 1000 and other clients, include:

  • Federal income taxation of banks, insurance companies, and manufacturers
  • Multistate apportionment and allocation of income
  • Transfer pricing among affiliated entities
  • Sales and use tax for retailers, manufacturers, and construction contractors

Tim has long been considered a “go-to” attorney on Wisconsin tax matters, both for out-of-state and Wisconsin-based companies. He regularly represents taxpayers with complex tax matters in administrative appeals, and in litigation before the Tax Appeals Commission and the Wisconsin appellate courts. It can be said that Tim “wrote the book” on Wisconsin taxes, as he is a principal author of The Complete Guide to Wisconsin Sales & Use Taxes, a treatise covering all aspects of the Wisconsin sales and use tax system, and the author of Wisconsin Business Taxes, an extensive examination of all Wisconsin business taxes.


Tim is also a highly regarded adviser on tax planning, for both federal and state tax matters. His counsel enables maximum tax efficiency for client mergers, acquisitions, and joint ventures. Representative transactions include taxable and tax-free reorganizations, restructurings, recapitalizations, and spin-offs of both public and private companies. Tim’s representation also regularly includes tax planning and structuring with respect to sales involving S corporations, partnerships and LLCs, transactions on which Tim also has lectured and written extensively. In the mergers and acquisition area, Tim is a noted expert on transactions involving deferred and contingent consideration and liabilities, having published a leading treatise on the subject.

Tim is a former Chair of the State Bar of Wisconsin’s Taxation Section. A thought leader on tax issues, he is a frequent speaker to legal and accounting groups across the country and served as an adjunct professor in federal income taxation for many years at the University of Wisconsin Law School. Tim also regularly advises taxpayers and trade industry groups with respect to developing tax policy, including the drafting and development of Wisconsin tax statutes and regulations, and has testified before state legislative committees concerning tax matters. 


In recent engagements, Tim has:

  • Successfully represented an online travel company in sales and use tax litigation before the Wisconsin Tax Appeals Commission, the Dane County Circuit Court and the Wisconsin Court of Appeals
  • Successfully represented a technology company in litigation before the Wisconsin Tax Appeals Commission with respect to the sales and use tax treatment of certain location and tracking services and related equipment

  • Structured the $500 million-plus sale of a subsidiary LLC for a medical and pharmaceutical services consulting firm
  • Structured the $100 million sale offer for a hospitality industry firm to a prospective buyer outside the U.S, so that the target U.S. shareholders would be afforded optimum tax deferrals
