The Streamlined Sales Tax Project may sound to some like the states are getting ready to start charging state <A HREF="http://www.eweek.com/article2/0,1895,1866715,00.asp">sales tax on all e-commerce purchases,</A> but the reality is that simple. What the SSTA (Streamlined Sales Tax Project), a group of U.S. states united in trying to simplify state and local tax collection, is doing is setting up a system by which Internet e-commerce companies can voluntarily pay state taxes to the states in which their customers reside. The carrot that the SSTA is offering companies that agree to do this is that, rather than try to work out how much tax a company owes for each locality they can instead use a CSP (certified service providers).
