The Illinois Supreme Court has become the first court in the country to find a federal law preempts a state law requiring sales taxes be paid on Internet sales, USA Today reports. The paper also reports: "the court determined that Illinois' 2011 'Main Street Fairness Act' was superseded by the federal law, which prohibits imposing a tax on 'electronic commerce' and obligates collection that's not required of transactions by other means, such as print or television." The issue might be primed for the U.S. Supreme Court as New York upheld its Internet sales tax-law and Amazon is appealing.
