A Reminder About The State Tax Implications of Passive Partnership Interests: U.S. Supreme Court Declines To Review State Court Ruling That Mere Partnership Interest Creates Income Tax Nexus

E-commerce companies that have affiliates doing business as (or even just investment interests in) partnerships or other pass-through entities in states in which the e-commerce company has no direct presence should be aware that such partnership interests may be deemed to create income tax nexus for the company.  A number of state laws and regulations provide that ownership in a pass-through entity establishes nexus for the owner.  See, e.g., 34 TAC Sec. 3.586(c)(13) [Texas]; 830 CMR 63.39.1(8) [Massachusetts]. To date, state tax tribunals have agreed. See, e.g., Shell Gas Gathering Corp. #2, N.Y. Tax Appeals Tribunal, DTA Nos. 821569 and 921570 (Sept. 23, 2010).
