This article focuses on three questions of state sales’ tax:

(1) What is the basic structure of states’ sales tax laws and how do these laws apply to electronic commerce?

(2) What are the existing federal constitutional restraints on the states’ power to impose sales taxes and how do those restraints limit the states’ ability to apply their laws to electronic commerce?

(3) What are the restraints on Congress – to whom this commission’s recommendations will be directed – in legislating to limit or expand state taxing power, or otherwise enact rules governing taxation of electronic commerce?
