Has the growth of tax-free Internet sales hurt state revenues or education funding? Is it "unfair" for sales over the Internet not to be taxed while other sales are taxed? Would imposing new taxes on the Internet do serious damage to the ability of this new form of commerce to thrive? Does the growth of tax-free online shopping pose a threat to traditional "bricks-and-mortar" retailers? This study addresses these and other questions in order to provide state, local, and federal policy-makers with the intellectual and empirical ammunition they need to keep the taxman at bay.
