Permanent Establishment Versus Nexus - Digital Economy Taxation


This is a virtual event, accessible over the phone. Access instructions will be provided after registration.


With widespread digitization of our economy, traditional models of nexus and permanent establishment are dissolving. Multinational companies may be expected to pay income, gross receipts, or net worth taxes to various jurisdictions. Our panel will evaluate where these developments will go in the future and how companies should plan for them.    

Educational Objectives:

• Understand the fundamental implications of South Dakota v. Wayfair on long-established standards of nexus and physical presence
• Learn how the Wayfair decision has impacted company’s tax planning and bottom line
• Gain insights into parallels between Wayfair and the allocation of taxing rights as part of BEPS 2.0
• Understand the position of U.S. Congress and U.S. Treasury in the OECD negotiations
• Evaluate how an OECD outcome on pillar one might affect different businesses

Moderator: Stuart Gibson
  • Director, International Tax
  • Bloomberg Tax & Accounting

Stuart Gibson joined Bloomberg Industry Group earlier this year after a 30-year career as a senior litigator in the tax division of the U.S. Department of Justice, where he handled high-profile matters such as the first tax shelter promoter summons cases, “Son of BOSS” tax shelter trials, and successful efforts to enforce “John Doe” summonses against large foreign banks. (If you ask, he will tell you he considers himself the illegitimate uncle of FATCA.) After leaving the government, Stuart wrote the chapter on IRS summonses for the current edition of Saltzman & Book on IRS Practice & Procedure. That gig led, in turn, to his nearly 3-year stint as editor at Tax Analyst where Stuart wrote, edited, blogged, and spoke at conferences in the U.S., Canada, and Europe on developments in international tax law. Immediately before joining Bloomberg Tax, Stuart worked in private practice in the Washington, DC office of Chicago-based Schiff Hardin LLP, where he represented taxpayers before the IRS and in court.
