This week the U.S. Supreme Court heard oral arguments for South Dakota v. Wayfair, regarding whether physical presence is required within a state for sales and use tax purposes, specifically addressing internet sellers. The case is challenging the Court’s 1992 decision in Quill v. North Dakota, 504 US 298, which upheld a decision from 1967 (National Bellas Hess v. Illinois, 386 US 753) and requires physical presence within a state in order to impose an obligation to collect sales and use tax on a vendor.
