The U.S. House Judiciary Committee held an oversight hearing November 30, 2011 on the constitutional limitations on states' authority to collect sales taxes in e-commerce. The hearing was set as Congress considers three remote sales tax proposals: the Main Street Fairness Act (S. 1452 and H.R. 2701), the Marketplace Equity Act (H.R. 3179), and the Marketplace Fairness Act (S. 1832) (click here for a summary of these proposals). The standing-room only hearing, which lasted nearly three hours, reflected increased interest in these proposals and hopes that a "breakthrough" could be reached after years of effort.
